THE THOMIST A SPECULATIVE QUARTERLY REVIEW OF THEOLOGY AND PHILOSOPHY EmToRs: THE DoMINICAN FATHERS OF THE PRoVINCE oF ST. JosEPH Publishers: The Thomist Press, Washington 17, D. C. VoL. X OCTOBER, 1947 No.4 THE INCONSISTENCY OF JEAN PAUL SARTRE'S LOGIC I F, in view of the public interest which has been centered about the novels and plays of Jean Paul Sartre by a sensational advertising campaign, we ask ourselves what will remain--or, indeed, what remains now-of his apparently subtle and new philosophy, we come to realize that its novelty has grown old very quickly and that existentialist psychoanalysis disintegrates thought more than it promotes or enriches it. In order for an idea to retain the attention of the public, it must be new in a much clearer and more real sense. Moreover, critiques have been written that are considerably subtler than those found in the analyses and audacities of works that are subtly paralogical. It would be interesting to gather together these studies that negate the most positive assertions of a writer whose logic ends up by destroying itself. An excellent example of this form of critique is the argument of Pierre Ayraud in his Reflexions 8Ur l' Etrre et le N eant, one of 393 894 MAURICE BLONDEL the essays m Temoignages (Cahiers de la Pierre-qui-Vire, August 1946). This study begins as follows: "A reading of l' Etre et le N eant makes one wonder if it is really necessary to refute Sartre. He has organised his system in such a fashion that acceptance of the initial premises of the book leads, little by little, to acceptance of the whole book. To the rejections of these premises the author will certainly object that it is unfair to criticize his philosophy on the basis of principles other than his own. Besides, Sartre is a subtle thinker, indeed, too subtle. Armed with his existentialist psychoanalysis, he quickly destroys his opponent's thought, reducing it to that game of mirrors in which the " pour soi " 1 triumphs only to perish more completely. It has to be said: A philosopher who considers serious-mindedness the supreme illusion of human consciousness is a priori not even worthy of criticism. Therefore, we shall not try to find out whether Sartre is right or wrong, whether he is a charlatan of genius or a poor fellow caught in the trap of his own dialectics. We shall try only to prove that his philosophy constitutes no threat whatsoever to our own basic theses. More than that, realism correctly understood permits us to perceive more clearly the hidden flaws in this phenomenological ontology that is neither ontological nor phenomenological. How explain the fact that Sartrian existentialism, expressing itself in a whole series of morbid literary works, was born and developed in the land of Descartes, although part of it came to France " in the baggage train of foreigners? " Is it simply a reaction against the rationalistic and idealistic trends which too long dominated philosophical thought in the nineteenth and at the beginning of the twentieth century, cutting that thought off from reality and life and making it sterile? Must we not recognize that this noisy explosion of existentialism has emotional roots and arose out of the frightful cataclysm of world war? 1 Sartre recognizes two kinds of being, "l'etre pour-soi" and "l'etre en-soi." The latter is the thick " viscous " impenetrable being of inanimate things and of man's past. The former is man's present being in which consciousness, "nothingness," and "choice " play the major role. INCONSISTENCY OF JEAN PAUL SARTRE's LOGIC 395 Certainly, philosophy must raise the question of the meaning of human existence, and all reflection should take into account the destiny of man himself. Philosophy is not only a scheme of ideas; it is the establishment of a position with regard to the Absolute and each one of us, at every moment, irrevocably stakes infinite values. But we must not allow the abuse of deadening abstractions to throw us into the sticky subjectivity of the hard existent, as the exaggerated systematization of Hegel drove Kierkegaard to clench his fists in a fideism of despair. Philosophy, which is an understanding of reality, is not based upon the particular, sunk or "stuck" in itself, nor upon bloodless generalities. When, with regard to action's internal springs, I try to describe the interlocking links of action, I never do it as if analysis were sufficient of itself, or as if description could be gratuitous. There are over-all structures, supra-individual standards, organic wholes, and intelligible syntheses. In short, there are regulative and judicative truths without which we would not realize that physical being constantly becomes stickier, like a homogeneous mass, nor that consciousness expands like a fullness overflowing, nor, above all, that the two oppose each other, either painfully to prolong their separation, or to project themselves, discovering in the unexpectedness of this leap forward the very essence of freedom from any value. If phenomenology continues to develop contradictory dialectics, it is because the modern phenomenologists have revived the divorce between the individual and the universal. They start by making sacrosanct one point of perspective, chosen arbitrarily, and then try to bring all the facets and values of existence into this perspective, cost what it may. This is the worst of all abstractions: to seek to reduce to an identical norm-arbitrarily conceived-the diverse reactions and needs of human beings which can be integrated only in a hierarchy of principles and values. If Sartrianism is only true for M. Sartre, we may say that it is no longer true, even for him; truth and universality are one. Once the initial perspective is distorted, the vision of the whole remains disturbed. What are these notions of "facti- 896 MAURICE BLONDEL tiousness," "utility," "existential choice," and even, of equivocal "transcendence?" The simple statement of a" pure" fact is unintelligible; the most elementary fact is always in some degree elaborated so that the penetration of the object by the subject began long before anyone declared that it was impossible. Similarly, what clear-cut idea are we to understand when the existentialists, in the mode of pragmatism, speak of the artificiality of the world? This notion turns back upon its creators to prove to them that, if the world is relative to their ability to construct it, far from being enslaved by " mundane:ness," they can dominate " mundaneness " by the absoluteness of the spirit. As for the idea of " pure choice," identified with the blind existential urge, it means only an obscure tendency, radically biological, with utilitarian or hedonistic fruits. If no coherent science can be worked out concerning existence, and freedom is conceived without an inwardness that is both demanding and sanctioning, not only does all metaphysics or morality become impossible, but all reason becomes impossible too. Finally, what shall we say of the caricature of transcendence that is offered us to designate in tum the exterior position of the existent with regard to himself, his primacy over nothingness, his very precarious control of the world and his anomite-like " project " within an illusory freedom. Now here is the authentic transcendence of the immanent and demanding Absolute discussed. And, fundamentally, it is logical that this system which has brought the mind down to the level of the irrational should bring transcendence down to the level of the unreal. From existentialism in the best sense of the word, the idea to be retained is that a practical and militant philosophy is necessary, since in the question: "What is being?" I am included and compromised to the point where I can no longer answer objectively without taking a stand for or against my own existence. It has been the goal of all philosophical effort to show that our idea of an act and the act itself are not the same in philosophy must be given to thing and that a proper that which until now seemed impossible to identify in the ex- INCONSISTENCY OF JEAN PAUL SARTRE'S LOGIC 397 treme diversity of the elusive contingency which attends concrete existences. But what can we retain of the negative existentialism? Its psychoanalytical explorations have revealed as yet unplumbed depths of egoism and perversity in man, rather than treasures of generosity. Can the existentialists be said to have enriched our knowledge of humanity by their contribution of cynical " totalism? " Definitely not, for the truth is always of the spirit. It disintegrates in descriptive complacency and the workings of an unhealthy imagination disturbed by animal cravings. Indeed, I have known this black existentialism so long, that I am eminently entitled to give my opinion of it. As early as 1880, the dilettantism then la mode advocated perverse experimentalism, and pessimism, which was widespread, glorified nothingness. None of this has changed. The modern existentialists do not really wish to solve the problem of existence; they wish to curb our right to raise the real problem. That is why they destroy, a priori, any relationship between the subject and the object, between the subject and himself, between the subject and other subject. But whom will they convince that man lives only for this disgusting "mess" and that he dies, if one dare say it, to prove the absurdity of life? Why must the irrational be the favorite food of man's reason, rather than that which transcends it and fulfills it? Doubtless, because reason can juggle with the unreasonable, while it must show itself humble before standards that go beyond it. It is high time that the French spirit and the French mind reaffirmed their rights to universality and inwardness, instead of allowing themselves to be deceived by an overly visceral imagination. a MAURICE .BLONDEL Unive'T'sity of Aix, Aix-en-Provence, France. THE PLACE OF HOLY SCRIPTURE IN THE THEOLOGY OF ST. THOMAS X CORDING to Pope Leo XIII, St. Thomas Aquinas was the leading exegete of Holy Scripture among the theologians of the Scholastic age. 1 It may therefore be of interest to study the place the Bible occupies in his works and in his theological system. The nature of theological science has always _been much discussed. Even in the time of St. Thomas there were differences of opinion on this subject/ and after having rested some centuries, the discussion has been reopened in modern times with more acuteness and more far-reaching consequences than before. The school of St. Thomas has always based its teaching on the explanation of the word "theology"; theology is the knowledge of God, and of created things in so far as they are related to God. The knowledge of God is a double one, natural and supernatural, and so there are today two kinds of theology, natural theology, called theodicy, and theology strictly so called, which is based on revelation. 3 Although essentially one, because God is one, theology has been divided into several sub-divisions. This is due to the ever increasing extension of theological knowledge, as well as to the different angles from which the fact of revelation may be considered. Revelation may be considered as something whose credibility must be proved and even defined against those who deny it; so originates the initial phase of theological science, called apologetics, or fundamental theology. Revelation, however, may also be considered from a speculative standpoint, in as much as one tries to penetrate it with the aid of speculative human 1 " Thomas Aquinas inter eos habuit palmam," in the Encyclical, Providentissimm Deus (Enchiridion Biblicum, no. SI). • Summa Theol., I, q. I, a. 8. • Ibid., a. I, ad 398 HOLY SCRIPTURE IN THE THEOLOGY OF ST. THOMAS 899 science. This gives origin to speculative theology, which tends to be considered by many of its students as the whole of theology; it deals with the truths of faith as they are found in the sources of revelation, and it .pursues a threefold aim. First, and principally, the speculative theologian seeks to understand and to penetrate into the terms in which the truths of faith are proposed to him. Secondly, he draws conclusions from the articles of faith with the aid of human knowledge and human reasoning. Thirdly, he has to invalidate the arguments which are brought against the articles of faith by those who consider those articles absurd. Besides speculative theology there is also what has been called positive theology. This does not try to penetrate the revealed truths, or the terms in which they have been revealed, by speculative thinking; its task is to indicate the revealed truth in its sources, and to explain these sources as far as they' are obscure or not fully understood. Holy Scripture is the word of God, not in the sense that it is identical with revelation, but in the sense that it has been inspired by the Holy Ghost and contains revelation. But although it is God's word," written for our instruction" (Rom. xv, 4), "that the man of God may be perfoct, prepared unto every good work " (II Tim. iii, 17) , it is not clear to everyone. The Bible ofte., reminds one of the book with the seven seals of the Revelation of Saint John. Often its sense is discovered only with difficulty, and not without the assistance of the Holy Ghost, which may be given to the individual believer, but which is before all given to the Church. The exegete tries to determine the sense of Scripture; he opens the seals of the closed book and tries to make clear what is obscure. In so doing he may use every human means: philology, history, anthropology, sociology, etc., but his work is theological, just as much as it is the work of theology to penetrate into the revealed truth with the aid of profane philosophy. The same must be said, with the proper adjustments, of positive theology which has tradition, considered as a source of revelation, as an object. Besides this, positive the- 400 J. VAN DER PLOEG ology has a defensive function. It defends Holy Scripture against those who deny its truth. It proves that the articles of faith which are not contained in the Bible, proceed from true divine and apostolic tradition. In the last seventeen years of his life, from his graduation as a Master of Theology in 1256 until his death in 1273, St. Thomas wrote commentaries on a number of biblical books: Isaiah, the Canticles, Lamentations, Jeremiah, Job, the Psalms, the Gospel of Matthew, the Epistles of St. Paul, and the Gospel of St. John. To these commentaries must be added the Catena Aurea or Golden Chain called by St. Thomas himself Glossae in Quatuor Evangelia. This is not a commentary written by the saint himself, but one continuous concatenation of texts of the Fathers, which explain the Gospels. Of all these works, only the commentary on the Canticles has not come down to us; the two commentaries on this book ascribed to St. Thomas and found in some editions of his work are now commonly considered to be spurious. The material extent of all these commentaries is as large as that of the Summa, and from this point of view they occupy an important place among the theological works of the doctor of the Church. St. Thomas' commentaries were written, either by his own hand, or by others who wrote them down during his lectures. The commentaries on the most difficult books, those of the Old Testament, were written by himself; most of those on the New Testament were taken down by his disciples. An exception must be made for the commentary on the Psalms and the commentary on the Epistles of St. Paul. It seems that St. Thomas explained the Psalms at the same time as he explained Romans and I Cor. i-x. The Epistles of St. Paul were considered more important and more difficult than the Psalms; therefore St. Thomas himself wrote the commentary on the above mentioned letters of St. Paul, but had the other ones written by one of his disciples. The Catena Aurea is wholly the personal work of St. Thomas. In many respects the medieval student did not differ from his HOLY SCRIPTURE IN THE THEOLOGY OF ST. THOMAS 401 modern colleague; taking good dictation and reproducing the words of the professor without mistake was not the accomplishment of every student. To take down his orally delivered commentaries, St. Thomas always chose someone whom he thought to be most capable of the work. During his first stay in Paris, those thus elected were a certain Peter of Andria, a Dominican, and a secular cleric whose name is unknown. From 1259 until his death, his confrere, Reinald of Piperno, who edited the spiritual heritage of the Master, functioned as his secretary. A commentary written by the professor himself was called expositio; one taken down by a disciple was given the name of lectura. Between the lectura and the expositio of St. Thomas there is hardly any difference of style, which may be an indication that he spoke very slowly in his lessons, or even dictated them. 4 In his other theological works St. Thomas cited a great number of scripture-texts and has interpreted separately very many of them, for example, the first chapter of Genesis as interpreted in the Summa. 5 St. Thomas also dealt with questions of introduction, but he never wrote a treatise on inspiratipn; his opinions on this subject may be gathered especially from his treatise& on prophecy 6 and from dispersed texts. The question of the sense of Scripture was dealt with by him several times. 7 In the beginning of his career as a teacher he treated the question of the canon, which was no problem in the middle ages,S although some fathers and doctors followed the dissentient view of St. Jerome. In his first public lecture, or principium as it was called in the middle ages, he gives a short survey of the books of both Old and New Testament. From the works of St. Jerome he knew the existence of varying texts of Holy Scripture, and it did not escape him that even the 0.

VAN DER PLOEG manuscripts of the Vulgate did not present identical texts. 9 Each of his commentaries is preceded by a short special introduction. H we wish to know why St. Thomas wrote commentaries on Holy Scripture and compiled such a work as the Catena Aurea, it is necessary to know the method of theological instruction in the 18th century and even earlier. In the time St. Thomas and in the early middle ages, every instruction was given on the basis of a standard-text. At present every professor is free in the choice of a handbook, and when he does not find one which pleases him, he reads or dictates a text of his own. In the middle ages this liberty did not exist. It was customary for every faculty to have its own fixed textbook or handbook, on the basis of which the lectures were delivered and which was discussed and explained by the professor. In connection with this text the professor could treat aH kinds of other questions, as the occasion offered itself. The difficulty of this method was that there could be no question of an orderly and systematic treatment of the subject-matter, which caused numerous repetitions in the lecture, disgust for learning and confused ideas for the as St. Thomas testifies. 10 At the faculties of theology and at all the schools where theological instruction was given, i. e. in monasteries and cathedral-schools, the Bible was already in the early middle ages the textbook. The professor bore the title of doctor or magister, or magister sacrae paginae, master of Holy Scripture, a title which became an academic degree given by the Church through the authorities to whom she had given a right to confer it. This title originally conferred a double right, just as it imposed a double obligation: to preach in the church and to explain publicly the Holy Writ, two functions and two duties which were closely connected. Soon a third duty was joined to the preceding ones, to hold and to lead public disputations, in • Cf., e. g., In Epist. ad Romanoa i, lect. 6 (Vives edition, XX, 897a); In Psalmoa, Proemium (Vives edition, XVIll, 280a). 10 Summa Tkeol., ·Prologua. HOLY SCRIPTURE IN THE THEOLOGY OF ST. THOMAS 408 which the master always had the last word. This right of the last word was exercised by him, at least in the 18th century, in the solemn, public, so called detenninatio or diffinitio of the magister, who held it the day after the disputation. In this the objections made against the thesis were considered in order and refuted by the master, and the disputed question thus settled. In the principium or inaugural address pronounced by St. Thomas on the occasion of his graduation as a master of theology, and which in many manuscripts bears the title of Commendatio Sacral Scripturae, the newly promoted says: " the doctors of Holy Scripture must excell by their excellent conduct in life, to be apt to preach with good success; they must be illuminated, to be able to instruct well; they must be well instructed to be able to refute errors in their disputations, in accordance with the words of the Apostle, who says that the ecclesiastical authority must be able to admonish with sane doctrine and to refute adversaries." 11 It is clear that the newly created master was considered a doctor of Holy Scripture; he must, first of all, preach Sacred Scripture to the faithful, because the revelation it contains has been given for the spiritual welfare of all; then he must explain it to those who can penetrate into its deeper sense, i.e. to the clergy; finally, he must defend it against those who attack it, or draw false conclusions from it. The disputations arose from the questions or difficulties put to a master on the occasion of a lecture on a special text of Scripture. Gradually the disputation disengaged itself from the normal instruction and became a separated actus scholasticus. In the 18th century it had in many places become the most solemn or even most important actus scholasticus, which lasted several hours and superseded the other lectures of the faculty which would have been held that day and the following one. The whole faculty could participate in it, with all the professors, the lower teachers and the students. It was what has been 11 Optuc. 40. 404 J. VAN DER PLOEG called by Father Mandonnet, whom we follow here, le tournai des clercs, the tournament of the clerks, 12 who went at one another, not with arms of iron and steel, but with the doubleedged sword of the spirit. Very early in the middle ages there appeared comments on Holy Scripture, first in the form of short glosses between the lines of the text, the so called glossa interlinearis, later in the form of more continuous explanations, often citations from the Fathers, and called glossa ordinaria or marginalia, because it was written on the margin of the sacred text. A great event for theological science was the appearance, in the middle of the 12th century, of the Liber Sententiarum of Peter the Lombard, in which for the first time in history a great number of the patristic texts were arranged systematically, and not according to the order of the sacred books of the canon. In the thirteenth century this book was used as a text book, not supplanting Holy Scripture, but in addition to it and subservient to it. Its purpose was only to help the student to a better understanding of the richness of Holy Writ. The interpretation of the latter remained the principal duty of the magister in his own lectures. Most masters found little satisfaction in delivering lengthy lectures, especially when the instruction was elementary and for which there was no remuneration. They shifted a part of the burden which rested on their shoulders to those of· subordinate teachers, well instructed and talented students, who aspired to the degree of master. In the time of St. Thomas, every master at the university of Paris could have two teachers of this kind who, under his direction, gave the elementary instruction. Both were called baccalarei or baccalaurei, although only the second had a right to this title. 13 The first was the so-called biblicus, also called biblicus ordinarius cursor 14 12 P. Mandonnet, 0. P., in S. Thomae Aquinatis Quaestiones Disputatae (Paris: 1925) , p. 8 (Introduction) and elsewhere. 13 For the original meaning of this word, see A. Kleinhans, 0. F. M., in Biblica, 1933, p. 391. u Mandonnet thinks that the cursor is not to be mistaken for the biblicus. Cf. HOLY SCRIPTURE IN THE THEOLOGY OF ST. THOMAS 405 or baccalaureus biblicus. His duty was to "read" the text of the Bible to his pupils and to explain it in a few words, cursorie, that is, without insisting on special questions, on the basis of the glosses or of parallel biblical texts. AmL.r.5 the Dominicans such a biblicus lectured every day, except on Sundays and church holidays; he had to finish the whole Bible in three years. 15 This method of teaching was called legere bibliam biblice, or textualiter, i.e., explaining only the letter of the text. It served to instill into the minds of the students first of all the knowledge of the biblical text; in the middle ages this took the place of our general and special introduction to Holy Scripture. Because the method had first been introduced in Paris and was later imitated everywhere else, it was also called legere bibliam secundum modum parisiensem (according to the Paris method.) After having studied seven years under the direction of Albert the Great, St. Thomas was appointed baccalareus biblicus at Paris in 1252; he performed this duty for two years. He began his first public lecture with the text of the book of Baruch: " This is the book of the commandments of God; all who observe them, shall come to life." 16 Of a higher rank was the baccalareus sententiarum, whose duty it was to read, and to explain if necessary, the Sententiae of the Lombard. His instruction was less elementary than that of the biblicus. St. Thomas was baccalareus sententiarum from 1254 to 1256, when he was promoted magister. Above the baccalaurei stood the magister. The best lessonhour of the day was reserved for him, viz. the first hour of the day, the hour when the spirit is freshest, after the night's rest. His title of magister sacrae paginae was changed in the first hal£ of the thirteenth century to magister sacrae theologiae, except, of course, in conservative England, which because of its insular character was more or less cut off from the outer world, Revue Thomiste, p. 503 ff.; Cardinal Ehrle was not of this opinion; cf. Kleinhans, op. cit., p. •• For this and the following, see Mandonnet, loc. cit. 16 Baruch, iv, 1; St. Thomas, Opusc. 89. 406 J. VAN DER PLOEG and where the title of magister sacrae paginae was kept at least a hundred years longer. The change of name was not without meaning, because it was connected with the influence of the Sententiae of Peter the Lombard and the rise of a systematic theology, which began to loosen itself from the text and the order of the Bible books, but not, of course, from their content. In spite of the change of name, the interpretation of Scripture remained the principal task and duty of the master; the textbook of his ordinary lectures was and remained the Bible. This is absolutely certain and the investigations of Denifle and Mandonnet have not left the slightest doubt in respect to it. 17 The magister sacrae paginae or theologiae did not explain the biblical text cursorie, that is, in a few words. He often entered deeply into its sense and consequences, especially as these offered difficulties or afforded an opportunity to speculative considerations. The master delivered none but the biblical lectures, at least if he was assisted by baccalaurei. If he had none, he took to himself the reading and explaining of the Sententiae at hand, or of another famous book. Because of the growing necessity of combatting false doctrines or opinions, the disputation was often considered more important than the ordinary lessons, which, therefore, were suppressed on the days when a master of the faculty led a disputatio or gave the determinatio which followed it. This was not a result of a diminished appreciation for Scripture, but was a pedagogical necessity. The masters of the university of Paris normally disputed only a few times a year. St. Thomas had a totally different idea of his duty as a professor and, probably to erect a barrier against the pernicious Averroism and the other vicious currents of thought which found many adherents at the university of Paris and elsewhere, he disputed two times a week during his last two stays at Paris (1256-59 Cf. P. Mandonnet, "Chronologie des ecrits scripturaires deS. Thomas d'Aquin," H. Denifle, "Que! livre servait de base a l'enseignement des maitres en theologie dans l'universite de Paris," Revue Thomiste, 1894, pp. 149-161. 17 Revue Thomiste, 1928 and 1929 (edited also separately); HOLY SCRIPTURE IN THE THEOLOGY OF ST. THOMAS 407 and 1269-72) , a thing unheard-of in that time. The determinationes included, every week four lessons of Holy Scripture had to be left out; Mandonnet has calculated that the total number of these lessons in the whole year was about sixty five, for there were many holidays and vacations. 18 During his stay in the Pontifical States of central Italy (1259-1269), St. Thomas conducted a dispute every fortnight, which brought the average number of his Scripture lessons to four a week.19 At Naples the Saint conducted no disputations during the year and few months he spent there at the end of his life, but he lectured on Holy Scripture about five times a week.20 The reason for this was most probably the fact that the university of Naples had not been founded, or approved by, the ecclesiastical authority, and therefore the theological faculty had no right to confer degrees, for which the assistance at disputations would have been necessary. 21 St. Thomas made up for the lack of disputations, not only by teaching Scripture every day, which was only his normal duty, but also by fulfilling the first, and too often neglected, task of the magistripreaching. During the whole of Lent, 1278, he sermonized daily to the students of Naples and the people of the town. 22 The commentaries St. Thomas wrote on different books of the Bible are nothing but the text of the lectures he delivered during the time he was magister sacrae paginae, from 1256 to 1278. St. Thomas was an ideal teacher, "the most complete type of the professor of the middle ages," as Mandonnet has typified him. 23 He delivered more lectures and disputations than any other professor of the university of Paris. He took care also to finish the annual matter of his course in the fixed Revue Thomiste, 19!l9, pp. 58-:11.; p. 68. Mandonnet, loc. cit., p. 187. •• Ibid., p. 185. 21 Ibid., p. 186. ucf.

VAN DER PLOEG time, except when he was transferred, in the midst of the academic year, from one place to another. So only two, or more properly three, of his commentaries are incomplete, viz. that on Jeremiah, which he left unfinished when he was unexpectedly called to Paris in 1269, and the commentary on the Psalms, during the writing of which he was surprised by death. He treated the Psalms and the Epistles of St. Paul at the same time, and so the commentary on the Epistles is also unfinished. But because he had already once treated the fourteen Epistles of St. Paul, Reinald of Piperno, who had written down this first commentary, combined both texts, making one of them, omitting the first part of the earlier lectura. 24 It seems that St. Thomas treated first a book of the Old Testament and then one of the New. At Naples he departed from this custom and dealt every other day with a book of the Old and of the New Testament respectively. In his choice of the biblical books he did not proceed arbitrarily. After his graduation he chose as lecture-matter the books of Isaiah and Matthew, which were often treated together in the middle ages. Of the four Gospels, St. Matthew was the most in favour, while the prophet Isaiah was considered a precursor of the evangelists, or almost as one of them, because of his many predictions of Christ and his work. 25 During his second stay at Paris, ten years later, St. Thomas chose the Gospel of St. John, in his flight of thoughts the loftiest and profoundest of the four. Amongst the books of the Old Testament he chose Job, in which the problem of Providence is discussed in such a thrilling manner. The great influence of Averroism, which the Saint came to combat, and which denied the existence of Providence, undoubtedly determined this choice. At Anagni, the place where the papal court was residing and where the central administration of the Church was established, St. Thomas explained the Canticles. •• Revue Thomiste, 1928, pp. 222 ff. •• Thus already St. Jerome; see St. Thomas, In Isaiam, In Prologum Hieronymi (Vives edition, XVIII, 670-671). HOLY SCRIPTURE IN THE THEOLOGY OF ST. THOMAS 409 The bride in the Song of Songs was generally considered to be a personification of the Church, and this may have influenced the Saint's choice. Why he has treated Jeremiah is not clear; perhaps simply because has was the second of the great Prophets. But it seems to be clear why he has treated the Psalms and the Epistles of St. Paul, the latter twice. Both books were the two most used biblical texts, and since the time of the early Fathers, a great many commentaries had been written on them. The Catena Aurea was compiled by St. Thomas at the request, or the order, of Pope Urban IV, who lived just long enough to receive the catena on Matthew. Two famous masters, Gilbert de la Porraye and Peter the Lombard, had compiled a similar collection of glosses on the Psalms and on the Epistles of St. Paul. Thomas, who as a true scholar knew that he was second to none of them, compiled a glossa on the four Gospels, for which he used a number of works of Greek Fathers hitherto unknown in the West, and some of which he had had especially translated for this purpose. This was a time when great endeavours were afoot for the reunion of the Greek and Latin Churches, and St .Thomas related his work to the actuality of the moment. He composed it from obedience, but it was so dear to him that he continued it and finished it off even after the death of Adrian. The work soon became famous and was given the name of " The Golden Chain." It is not impossible that St. Thomas used the text of it in his lessons, during the time he was working on it. If so, those lectures had more the character of the lessons of a baccalareus than of those of a magister. The form of the commentaries was prescribed by custom. To us it may seem somewhat artificial with its many divisions and subdivisions, but these were deemed necessary in that time, since the good teacher was he who made good distinctions (qui bene distinguit, bene docet.) Moreover, St. Thomas knew how to free himself from the scholastic method of exegesis, as, for instance, in his adinirable commentary on Job, called by a 2 410 J. VAN DER PLOEG medieval scholar a mirabile opus. 211 The first exegetical rule of St. Thomas was, apparently, to explain the Bible by the Bible, and therefore many passages of his exegetical works, especially of the earlier ones, in which one still tastes the baccalareus biblicus, consist more of biblical texts than of the text of the author. And if one considers that a part of these texts were not written down by St. Thomas himself, but by others, one cannot but admire the memory of the Saint, and understand why it was said of him that he knew the whole Bible by heart. In comparison with the citations from Holy Scripture, the Fathers are not cited so often. With regard to the sense of Scripture, St. Thomas gives first the literal one and then the " higher," or spiritual sense. In the latter he is rather sober, when compared with some of his contemporaries. In his commentary on Job he follows only the literal sense, because, so he informs his readers, there is nothing new to be said on the spiritual sense since the commentary of Pope Gregory! In his commentaries he tries to be exact and accurate and to omit nothing, rightly judging that everything in the sacred text deserves the full attention of the exegete. It should not be thought that the great thinker, as a speculative theologian, gave attention only to that which, in his eyes, was of "theological " importance, that is, of importance for his theological system. His reverence for the word of God was too great to do this. As a true exegete, he took notice of the smallest details 'of the text, of the names of persons and places, of the mysterious" titles" (headings) of the Psalms. He would leave nothing obscure or undiscussed. Thus he was fully what an exegete of those days and, mutatis mutandis, also of our days should be. After this historical discussion of the place which the interpretation of the Bible occupied in the theological work of St. Thomas, the question arises as to the place Holy Scripture holds in his theological system. St. Thomas deals with this problem in the first question of his theological handbook, the •• Thus John of Colonna; cf. Mandonnet, Revue Thomiate, 1928, p. 149. HOLY SCRIPTURE IN THE THEOLOGY OF ST. THOMAS 411 Summa. It has been explained above that in the middle ages the science of theology arose from the interpretation of Holy Scripture and that its higher form, its scope was to provide a deeper insight into the Bible's revealed truths. Now it is very remarkable that St. Thomas, when he speaks in the first question of the Summa on the nature of theology, uses the terms sacra doctrina, sacra scriptura, scientia divinitus inspirata, divina revelatio, apparently indiscriminately. This occurs in the first article, and again at the end of the second. Holy Scripture and sacra doctrina are even equalized by the word seu (sacra scriptura seu doctrina.) Remarkably enough the word theologia is used only a few times. At the end of the first article it is said that theology " belongs to sacra doctrina " (theologia quae ad sacram doctrinam pertinet); this gives the impression that according to St. Thomas, theology is only a part of sacra doctrina. But in article seven, " this science," viz., the science of which he has been speaking, consequently sacra doctrina, is called theology: " In this science God is spoken of, for it is called theologia, quasi sermo de Deo." Elsewhere St. Thomas is still more explicit, as he says in the preface of his commentary on St. Paul, when speaking of the Psalms and the Epistles of the great Apostle: " These writings contain nearly the whole doctrine of theology." And in the same preface, written at Naples at the end of his life, he says: "In the New Testament one reads, after the Gospels, the doctrine (doctrina) of the apostles." In the second difficulty, made in article seven, against the thesis that God is the object of the sacred science, he says: "all that which is spoken of in a science belongs to the subject (St. Thomas does not say object, as we do) of it; but in Holy Scripture much is said of things other than God; therefore God cannot be the subject of this science." And the answer runs: " all which is spoken of in Holy Scripture is spoken of God; the objection, therefore, is worthless." It is clear that in this argument St. Thomas identifies Holy Scripture and sacred science. In article eight he asks whether the sacra 412 J. VAN DER PLOEG doctrina is argumentativa or not, which is to ask whether it reasons, whether it concludes, etc. His answer is that the sacred doctrine does not argue to prove its principles, that is, the articles of faith. And somewhat further he continues: "Holy Scripture, which has no (science) above it, disputes with him who denies its principles, and argues if ... " etc. In article nine he answers the question, " Should Holy Scripture use metaphors? " by saying: ". . . the sacra doctrina must use metaphors." It cannot be doubted: Holy Scripture contains, or rather is sacra doctrina and a science. How is this possible? That one may call Holy Scripture a doctrine, may readily be understood, since it teaches us so many things. But for St. Thomas a science is something else, that is, a cognitio per causas. Can Holy Scripture be spoken of thus? The answer to this question is threefold. In the first place, sacra doctrina is a different kind of science from the profane sciences. These are ultimately based on human experience, human understanding; theology,. however, is based on the science which God has from Himself, and this is also the ultimate reason why we believe in the truth of the Bible, inspired by God, who is Himself nothing but truth. Secondly, Holy Scripture contains reasonings; St. Paul, for instance, concludes from the resurrection of Christ to the resurrection of all men (I Cor. xv, 12.) But this is no complete answer. St. Thomas asks himself too, if theology is one single science; the difficulty is obvious, since theology seems to deal with a great many things which belong to the realm of other sciences, especially philosophy. He answers that theology refers all these things to God in so far as they are revelabilia. The sense of this word is not immediately clear, but it can be obtained from the context. 27 The object of the common sense (sensus communis), so he says some lines before, is that which can be perceived by the a full discussion, cf. E. Gilson, Le Thomisme, Introduction a la philosophie de S. Thomas d'Aquin, 4th edition (Paris: Introduction (" Le Revelable "), pp. 8-40. HOLY SCRIPTURE IN THE THEOLOGY OF ST. THOMAS 413 senses (the sensibile); this includes the visibile and the audibile. It seems therefore that the strange word revelabile has been formed in the same way and indicates the object of sacred science. The ear does not perceive the audible before there is sound; thus the revelabile is only the object of sacred science when there has been revelation, and therefore Sertillanges translates it as " objet de la revelation." 28 So theology considers everything which is contained in the revealed object. When we know from revelation that Christ is man, or that man must serve God, the idea " man " has become the object of revelation. Therefore St. Thomas analyses it and many other ideas in order that we might better understand the sense of the revealed truth. This understanding is, of course, human, fallible, and not to be identified with faith. It is the product of theological thinking. But this thinking would not be theological, if it did not find its origin in the revealed truths, which have been written down for us in Holy Scripture. Thus we find in Holy Scripture the principles of sacred doctrine, that is, the articles of faith, which are short summaries of the revealed truths; we find in it argumentations and reasonings and the refutation of errors. The theologian continues this work, making use of every human science, especially philosophy. This makes it clear why, according to St. Thomas, Holy Scripture, sacred doctrine, revealed science, and theology are one and are not essentially distinguished. Holy Scripture and (human) theology are organically tied together and can never be separated. St. Thomas would emphatically deny the modern saying of some theologians, that (literal) biblical exegesis is no theology, and the exegete of the Bible no theologian. But to be able to be used in sacra dootrina, the sense of Holy Scripture must be clearly defined. According to St. Thomas, and to the medieval theologians commonly, the text of Holy •• Cf. the French translation of the Summa; Saint Thomas d'Aquin, Sommd Theologique, Dieu, (Paris: I, on p. 80, Father Sertillanges translates " divinitus revelabilia" by " tout ce que peut reveler Dieu." 414 J. VAN DER PLOEG Scripture may have more than one sense: a literal or historical, and a spiritual, higher, sense. The doctrine of the plurality of the senses of the Bible is old and occurs in the Epistles of St. Paul. From then up to the present time, there is an uninterrupted chain of " spiritual " interpreters of Scriptures. Many people do not understand this and think that the attributing to Scripture of a " spiritual " sense was only a remarkable or odd use of the ancient Church, taken over from Alexandrian Judaism. One needs only to read Origen, the greatest allegorizer of Scripture of all times, and also one of the greatest Christian scholars, to know that allegorizing was for him no vain game of the spirit, but the bitter earnestness of a profound Christian, who had too high an idea of Holy Scripture, of which God was the Author, to admit that the many commonnesses which occur in it had not a higher, spiritual, mystic sense, hidden from the eye of the carnal man, but open, under the light of grace, for the spiritual one. The allegorizing interpretation of Scripture was in the old Church an attempt to take the whole Bible, with all its details, into the service of the preaching of the word of God and of Christian life. Origen, and the Alexandrians generally, went too far. The school of Antioch, with Theodore of Mopsuestia and John Chrysostom as its most prominent representatives, tried to readjust the exegetical balance by the doctrine of the theoria 29 and the types. The first occurs also in St. Thomas, although not under the same name. Theodore went too far and in 553, more than a century after his death, was condemned by an oecumenical council, at the instance of the Greeks. But the more moderate doctrine of Antioch stood firm, and at Alexandria the purely allegorical exegesis was gradually pressed back into the domain of the homiletical, the devotional, whilst in the dogmatical controversy literal exegesis prevailed. St. Thomas, in his doctrine on the plurality of senses of Holy Scripture, is a disciple of Antioch. Practically he distinguishes a double sense of Scripture only, not a fourfold 29 For the sense of this word, see A. Vaccari, S. J., in Biblica, 1920, pp. 3-36. HOLY SCRIPTURE IN THE THEOLOGY OF ST. THOMAS 415 sense as others did: a sense of words and one of things, events. The first is the literal or historical sense, and has been given to the text by God as well as by the inspired writer; the latter is the spiritual sense, and has been attached by God, not to words, but to things, facts, or persons, which became thus figures, types, of the future. With certainty this sense can only be known from revelation, that is, from Scripture itself or from divine Tradition; it may be surmised when there is a great resemblance between the figures of the Old Testament and the realities of the New. 80 In so far as it is not explicitly revealed, the spiritual sense is always uncertain and therefore cannot be used in sacra doctrina. But by this nothing is lost from the revealed truth, since, as one reads in the Summa, " Scripture does not contain in the spiritual sense anything necessary for faith which it does not clearly teach elsewhere in the literal sense." 81 And in Quodlibetum (VII, art. 15, ad 3) it is said: "Nothing is taught mysteriously (occulte) in any place of Scripture which is not explained clearly elsewhere; therefore, the spiritual explanation must always be based on the literal." But is the literal sense itself manifold? St. Augustine in two texts deemed this possible, and it seems clear that St. Thomas, who cites the words of the famous doctor and who deals with the problem three times, 32 did not dare to contradict this flatly. In one place the opinion of the great doctor of the old Church is called by him " not incredible " 33 and in the Summa he calls it " not inconvenient." 34 God, indeed, is the principal Author of Holy Scripture; He knows better than we the various senses a word may have, and therefore it is not impossible that in His Wisdom He has given the words of the Bible more than one sense. It is possible that the sacred authors knew this sometimes and, to illustrate this, St. Thomas cites •• Quaes. Quod., VII, a. 14, ad 4um. 11 Summa Theol., I, q. 1, a. 10, ad 1um. •• Ibid., a. 10; Quaes. Quod., VII, a. 14, ad 5um; Q. D. de Pot., q. 8, a. 1. •• Q. D. de Pot., loc. cit. u Ibid. 416 J. VAN DER PLOEG the example of the prophets, who, speaking of figures, also intended to speak of their ful:filment.85 Sometimes the sacred writers of the Old Testament knew the prophetic signification of persons or things and made use of this knowledge in their words or writings. 36 In these cases their words may have a double literal sense. In the second and twenty-first Psalms, for instance, David speaks first of himself when he says: "The princes came together against the Lord and against his Anointed," or " God, my God, look upon me, far from my salvation the words of my misdeeds," but he chiefly intends to speak of the passion of Christ of which his own passion was but a figure. This is evident because in both Psalms David says things which can be applied only to Christ, such as: " The Lord hath said to me: Thou art my son, this day I have. begotten Thee," or "they have pierced my hands and my feet; they have numbered all my bones." 87 The last method of interpretation is wholly that of the school of Antioch and supposes with the prophets what was called by the Antiochians 6ewpla, which means the beholding of persons or things of the future in persons or things of the present. 88 St. Thomas gives no other examples of the plurality of the literal sense, and in the well-known text of De Potentia (IV, I) he concedes the " non-incredibility" of the opinion of St. Augustine. Here he considers the interpretation of the words of Moses-" and the earth was waste and empty," that is, whether he is speaking of " formed " matter or of matter which was yet to receive its forms in the work of the six days. Both interpretations are possible, he says, both can be "adapted" to the text (aptari possunt) . No one has a right to claim a monopoly for his personal exegesis. In this case, Scripture uses abstract terms which mean something concrete; two •• Quaea. Quod., VII, a. 1. •• Cf. Quaea. Quod., VII, a. 14, ad 5um; In Paalmoa, Proemium (Vives edition, XVIII, 280b). •• In Paalmo8, 8'UM locia. 38 In his commentary on the Psalms, Proemium, St. Thomaa attributes this opinion to St. Jerome. HOLY SCRIPTURE IN THE THEOLOGY OF ST. THOMAS 417 concreta are possible, and i£ God had intended both, one could say that Genesis (i, 1) would have a double literal sense. The. latter is not a conclusion of St. Thomas, who never says anything of the kind, although he often gives more than one explanation of difficult texts. From this silence it may be inferred that in cases like this he did not admit the existence of more than one literal sense as intended by God or by the sacred author. In the question of prophecy, there is never a plurality of totally inadequate literal sense, there is only what has been called a virtual plurality; in the cases of the second and twenty-first Psalms, for instance, the historical and the messianic interpretations are connected as figura and figuratum. Practically St. Thomas recognized the existence of one, adequate, literal sense. St. Thomas agrees with this conclusion in the answer he gives to the difficulty: " When Scripture has more than one sense, it cannot be used as a basis of argumentation." In this answer one reads, among other things: "The senses (of Holy Scripture) are not manifold because one word would have many senses . . . all the senses are based on one, namely the literal." 39 By ascertaining this and practising it, St. Thomas has maintained the usableness of the sacra doctrina, which would necessarily be endangered if one word, one single expression had many not adequate or subordinated literal senses. In connection with what has been said, a difficulty of a totally different character arises. Reading what St. Thomas writes on the relation between Scripture and revelation, one gets the impression that both are put by him on a par, or at least that he considers Holy Scripture as the only existing source of revelation. In this he seems not to be alone; a certain number of texts of Fathers of the Church give the same impression and the reformers of the sixteenth century cited them in confirmation of their doctrine of the sufficientia Sacrae Scripturae. Moreover, does not St. Thomas say explicitly that all that is necessary for faith can be read clearly and in the literal •• Summa Tkeol., I, q. 1, a. 10, ad 1um. 418 J. VAN DER PLOEG sense in the Bible? Is this not the Protestant doctrine of the perspicuitas of Holy Scripture, and does this not practically exclude tradition as a source of revelation? One must concede that St. Thomas rarely mentions tradition as a separate source of revelation. But this does not mean at all that he did not know it. A locus classicus used by every ecclesiastical writer is his commentary on II Thess. (ii, 15.) Saint Paul wrote: " Brethren, stand fast and hold the traditions which you were taught, whether by word or by epistle of ours." In his commentary on this text, St. Thomas remarks: " So it is clear that much has not been written in the Church which has been taught by the apostles and which, therefore, must be observed (servanda) because, according to the judgment of the apostles, it was better to hide much, as Dionysius says. Therefore the apostle says in I Cor. (xi, 34): The rest I shall order when I come." 40 St. Thomas refers to the apostolic tradition especially and principally in the doctrine of the Sacraments. Here he often cites the above mentioned Dionysius, who was for him a disciple of the apostles and who, therefore, would be better acquainted with their doctrine than the later doctors. The form of the Sacrament of Confirmation, instituted by Christ, is known to us only from the doctrine of the apostles. 41 In his commentary on Job, St. Thomas says that the opinion that the devil is a fallen angel belongs to the tradition of the Church (ecclesiastica traditio) ,42 thus using explicitly the word "tradition." But in spite of all this, Holy Scripture was for him by far the principal source of faith, especially with regard to the more speculative doctrines. The " necessary " truths of faith, so he says, following St. Augustine, are all clearly formulated in Holy Scripture. The meaning of this term " necessary truths " is at first not very obvious. From what has been said above it appears, for instance, that the form of the Sacrament of Confirmation (the •• In II Thess. ii, lect. 8 (Vives edition, XXI, 446b). u Summa Theol., III, q. 72, a. 1, ad I urn; see also q. 74, a. 4, ad I urn. •• In Job i, lect. 2 (Vives edition, XVIII, 6). HOLY SCRIPTURE IN THE THEOLOGY OF ST. THOMAS 419 necessary ceremonies to administer it validly) is not included in it. For all that, it is in a certain sense necessary to know it. On the other hand, it seems not to be sufficient to include in these " necessary truths " only the four principal articles of faith: existence of God and Providence, Salvation, and the Trinity, because if only this could be read clearly in Holy Scripture, it would not be very much. Perhaps St. Thomas was thinking of the principal symbola/ 3 or perhaps he left to St. Augustine the determination of the term " necessary." It should be borne in mind that the Bible, as Holy Writ, as a book, can easily be consulted, whilst it is often very difficult to deal with the data of tradition in as much as this does not appear from the statements of Councils, or from the universally accepted belief of the Church. This fully accounts for the general custom of the Fathers and also of St. Thomas of appealing to Scripture for proof of the truths of faith, or for proof of their own opinions. There is one form of tradition, however, on which St. Thomas often depends, even unconsciously. This is the traditional interpretation of many passages of both Old and New Testament-interpretations hallowed by tradition, confirmed by the verdicts of Councils or Popes. According to St. Thomas the general Councils of the Church only explain the teaching of the Scripture to which they appeal. Illuminated by the Spirit of God they explain to us infallibly the sense of the sacred text. The Fathers also have interpreted Holy Scripture, but in this they were not infallible. The idea and the term " unanimous opinion of the Fathers" (unanimis consensus Patrum), which occurs so often in Catholic theology since the Council of Trent, is not met with in the works of St. Thomas, who speaks nevertheless of " the faith of the whole Church," 44 which is much the same idea. •• In his Expositio super Symbolo Apostolorum (Opusc. 33), St. Thomas repeatedly speaks of " necessary " truths of faith. u G. Geenen, 0. P., "De Opvatting en houding van den H. Thomas van Aquino bij het gebruiken der bronnen zijner theo!ogie,"-Bijdragen der Nederlandschl! Jezuieten, IV (1938), 144. 420 J. VAN DER PLOEG This leads to a last question. Has St. Thomas as an exegete made a good and fair use of Holy Scripture, has he interpreted it faithfully and has he taken it objectively as a base for his theological speculations, or has he tried to force upon the Scripture a sense in accordance with his own views? Has he tried to shelter in his commentaries, with all their Scholastic distinctions and subdistinctions, his own Scholastic system, heavily drenched with the theories of Aristotle instead of with the spirit of the Gospel? One example out of many! It is well known that St. Augustine distinguished three kinds of sins: sins against the neighbor, against God, against oneself. In the text of the Vulgate, the first verse of the book of Job, it is said that Job was a simple and upright man, who feared God and kept from evil. To this St. Thomas applies St. Augustine's threefold division of sins; he says that the words "Job was an upright man " mean that he did not sin against the neighbor; " he feared God" means that he did not sin against God; "he kept from evil" means that he did not sin against himself. No modern exegete would borrow from St. Thomas this interpretation, and rightly so. One thing is certain. In his exegesis St. Thomas never had the intention of forcing upon Scripture a sense it does not have. "We must keep to that which has been written in Scripture," he says, " as to an excellent rule of faith, so that we must add nothing to it, detract nothing, and change nothing by interpreting it badly." 45 After St. Thomas there have been theologians for whom the Scholastic system was (practically) the principal matter and the interpretation of Scripture a secondary matter, but such a mentality is far from the mind of St. Thomas. That he interpreted Scripture in accordance with the ideas of his time is understandable but for this he is not to be reproached. In point of fact, every exegete explains Scripture thus. That he explained it in accordance with the authority and the common opinion of the Church was his good right. So far as the clear passages are concerned, which have always been •• St. Thomas, In De Divinia Nominibua, Chap. II, lect. I. HOLY SCRIPTURE IN THE THEOLOGY OF ST. THOMAS 421 rightly interpreted by tradition, this is self-evident. With regard to the less clear passages, these must be interpreted as much as possible under the guidance of the same Spirit which has inspired them, 46 but this is guaranteed to the Church in such a manner that everyone has to submit himself to her judgment. 47 As far as the many Scholastic distinctions are concerned, St. Thomas, using them as was customary in his time, had no intention whatsoever of doing violence to the text. To be brief, let us only examine the example from the commentary on Job. St. Thomas had inherited from the Fathers a great respect for Holy Scripture. In it everything is full of sense, nothing is superfluous. Therefore it could not be without sense, and without a special sense, that it was said of Job that he kept from evil, after it had been said that he did not sin against God and against his neighbor. Could not that be an indication that sins of Job against himself were meant? Certainly the inspired writer meant that Job did not sin at all, which, theologically interpreted, included the fact that he did not sin against himself. We may, therefore, say that the interpretation of Job (i, 1) by St. Thomas gives something more than the bare rendering of the ideas of the inspired author; it goes deeper; it may be called a "theological" rendering.· The modern exegete would certainly not go so far. As far as the present case is concerned, he knows better than St. Thomas that the Orientals have a way of speaking and of writing which is different from ours, that they are often prolix and that they like using synonyms and parallel expressions. But can one reproach St. Thomas for being less fully aware of this than we are? Thus the unity of sacred doctrine is perfectly clear with St. Thomas, and also the highest place Holy Scripture occupies in it. He did not spend all his time in explaining the letter of Sacred Scripture, although he did nothing else in his ordinary lectures after his graduation as a master. But he spent his •• Quaea.

Theology is one science; it is like a stream whose waters move forward in various branches; it is like a body with many limbs; all are necessary for the welfare of the whole and none has the right to extol itself above others. May the modem theologian and exegete understand this. Not everyone can be a specialist of biblical exegesis as it has been developed today, but every theologian needs to see that his science is always in a permanent, living contact with Holy Scripture, under the penalty of becoming sterile, or worse. If he does so, he only follows the example of the great Master. J. VAN DER PLOEG, 0. P. Ecole Biblique, Couvent de St. Etienne, J eru8alem, Palutine. THE EFFECT OF BODILY TEMPERAMENT ON PSYCHICAL CHARACTERISTICS M UCH INTEREST centers to-day in the study of what modern psychologists call" personality." Hardly any two of these psychologists agree as to what, precisely, constitutes "personality," but there is a more or less general agreement among them that it has to do with all the individual psychical and even physical characteristics which distinguish one man from another. But since there is no agreement among them as to just what the " characteristics " of man are, one writer will discuss personality from the viewpoint of one group of characteristics, another from the viewpoint of an entirely different or perhaps overlapping group. As Gates says, the term "personality," ... is likely to be misleading. It is sometimes used to imply a specific human trait or a small number of traits. Thus one author states that personality consists of physical appearance, social attitudes, and intelligence; another that it comprises intellect, character and temperament; another that it involves intelligence, emotionality, sociability, volition and morality ... The statement that personality depends upon two or three or some other number of traits means merely that the author has arbitrarily classified the whole series of reaction tendencies in two or three or some other number of groups.• The difficulty lies not so much in the arbitrariness of the classifications, as in the fact that none of the classifications includes all the characteristics which pertain to individual differentiation. Realizing the impossibility of arriving at an adequate knowledge of the individual person by considering only one or two or three of his characteristics, another group of moderns-physi1 A. I. Gates, Elemtmtary Peyckology (New York, 1928), pp. 518-19. (By permission of the Macmillan Company, publishers.) 428 LEO M. BOND cians, psychiatrists, anthropologists, mostly Italian, French, German and American-has undertaken the study of the individual with a view to determining by accurate empirical observation everything that is knowable about him, the proportions of his body, the structure and function of his organs, the quality of his mental and emotional reactions, etc. They seem to be under the impression that once they have catalogued all the phenomena exhibited by man, they not only will have accounted for his personality, but will have arrived at a knowledge of everything that can be known with certainty about the " whole " man, including his very nature. To attempt such a study, is, to be sure, a great undertaking, and, as might have been expected, it has not escaped the consequences of the tendency of specialists to be influenced in their interpretation of the whole by their particular knowledge of a part, to say nothing of the basic fallacy upon which such a study rests, namely, that everything knowable about man and his nature can be learned from empirical observation alone. However, these men have taken a step in the right direction, for the very fact that they attempt to arrive at a knowledge of man as a " whole " indicates that they have some appreciation of the fact that man is a whole and functions as a whole and must be studied from a "whole-making" point of view. But more important than their notions as to what constitutes the " whole " man is the very valuable data which this group of investigators has accumulated with regard to the actual observable effects of organic conditions upon psychical activities, information which contributes more than a little to a better understanding and appreciation of a primary psychological question-the bodysoul relationship. When we speak of these investigators as a " group," we do not intend to imply that they have, in all instances, been working in pre-determined or conscious collaboration, with one specific object in mind, for, although they are all more or less contemporaries and have undoubtedly been familiar with and have even used and built upon each other's data and conclusions, their disagreement in terminology and the variance in EFFECT OF BODILY TEMPERAMENT emphasis which some have placed upon this or that aspect of the question would indicate that their grouping together is justifiable only on the basis of a common general viewpoint and purpose, the study of man as a unit, beginning with his physiological constitution-particularly his endocrine glandular pattern-and arriving ultimately at a knowledge of all his individual characteristics. The work of this group, at least as to systematic investigation, may be considered as beginning in 1890 with the founding by Achille de Giovanni of a school of clinical anthropology in Padua. The observations reported by de Giovanni as to the correlation between the morphology of the body and the individual psychical characteristics aroused considerable interest and became the starting point for a series of further investigations and studies along the same lines, the most important of which, at least in the Italian School, have been conducted by Nicola Pende in his institute for the study of the human individual. In two books: Endocrinologia; Patologia e Clinica Delle Glandole A Secrezione lnterna, and Le Debolezze di Constituzione, Pende made a detailed study attempting to show the correlation between the physique, temperament, and character of an individual as determined by the interbalance of the secretions of his endocrine glands. These and two other books, La Biotipologie Humaine, and Biotipologia Umana ed Ortogenesi, are considered the outstanding contributions of the Italian School to the study of what has been recently christened " Constitutional Psychology," which for the endocrinologists is practically synonymous with "Endocrine Psychology." Other important contributors are Le Legge de Correlzazione Morfologia dei Tippa Individuali, by Giacinto Viola, and Endocrinologia, by S. Distefano. In France, Sigaud, a physician and contemporary of Di Giovanni, undertook a series of experiments to establish the correlation between temperament, morphology, and psychical qualities. He and his followers concluded that temperament was the primary determinant of morphological and psychical individual differences. Sigaud expresses his views on tempera3 426 LEO M. BOND ment in his Traite Clinique de la Digestion, and in a second work, La Forme Humaine, correlated temperament with the morphology of the human body. His most outstanding disciple was Leon MacAuliffe who later, however, departed somewhat from his master's doctrine on temperament. In Germany, the most outstanding contribution to the subject was made by Ernst Kretschmer in his Koperbau und Charackter published first in 1911 in Berlin and since then many times reprinted and translated into other languages. Kretschmer was primarily a psychiatrist, but from his observations on the correlation between bodily structure and the two forms of insanity known as schizophrenia and manic-depression, he evolved a theory of personality which he considered applicable to normal people also. He too conceived of personality as the total product of bodily constitution, temperament, and character. His classification of morphological types into " pyknic," " athletic " and " asthenic " (later reduced to " pyknic " and " leptosome ") , and of psychical types into " schizothymes " and " cyclothymes " has become famous and is widely used by psychologists and psychiatrists. Most of these men are, as we have already noted, primarily physicians, anthropologists, or psychiatrists, but in the course of investigation in their various fields, so striking was the correlation observed between physiological states of the human body and mental and emotional characteristics, that they were forced, so to speak, into the field of psychology. The physicians soon realized that a knowledge of their patient's psychical make-up was a valuable aid in the diagnosis of his physical maladies; the psychiatrists found that various types of mental abnormality could be more easily determined through correlated constitutional inadequacies. Interested first in abnormalities of body and mind, these investigators soon inclined to the view that the distinction between " abnormal " and " normal," on the· mental side as well as the physical, was simply a difference of degree, not of kind, so much so that every person by reason of his own peculiar, individual, constitutional make-up, had tendencies toward certain types of physical and mental EFFECT OF BODILY TEMPERAMENT 427 abnormality, in such a way that, were he to become sick at all, it would probably be with definite, predictable diseases, and were he to become mentally deranged at all, he would develop a certain type of insanity. Thus the clinical observation of abnormalities threw much light upon the nature and causes of the individual physical and psychical differences so obvious among ordinary normal people. Many of these investigators were particularly impressed with the role played by the glands of internal secretion or endocrine glands-the thyroid, pituitary, adrenals, etc.-in the determination of individual physical and psychical characteristics. Many of them are convinced that the endocrine glands are the primary cause of all individual differences; some say "probably," a few, only "possibly." In America, many medical men specializing in the study of endocrine glands are becoming more and more interested in the psychological aspect of the question and are already using somatic and psychical characteristics as diagnostics in the determination of endocrine disorders. Most of these physicians are, however, still primarily concerned with pathologies of the endocrine glands and how to cure them. But some have become so fascinated by the prospect of a "new psychology" of the endocrine glands, that they have stepped out of their clinics long enough to write books about it. Perhaps the most enthusiastic of this latter group, on the American front, is Dr. Louis Berman, of New York, who, in his work, "The Glands Regulating Personality," becomes almost lyrical in his enthusiasm for the glands of internal secretion as the " Open Sesame " to all the mysteries of human nature. Another enthusiastic student of the subject, in America, is Sante N accarati, the American spokesman of Pende and the translator of his works, who himself has contributed considerably to the literature on the subject, especially by his articles in various Journals of Psychology. 2 2 " The Morphological Aspect of Intelligence," Archives of Psychology, XLV (1921). "The Influence of Constitutional Factors on Behavior," Journal of ExpMimental Psychology, VI (1928), 257. "The Relation of Morphology to Temperament," Journal of Abnormal and Social Psychology, XIX (1924), 268. 428 LEO M. BOND These are but a few of the more outstanding proponents of what might be called the "endocrinal theory of personality" or, more precisely, the "endocrinal theory of temperament," since temperament is for them the basis of personality. They have, in their writings, dealt with the subject from the" whole·making" point of view. The literature on various and particular phases of the question is inexhaustable. By profession these men are scientists. They claim to be concerned with the study of man only from the viewpoint of the " facts " about him, which, they say, can be determined only by accurate empirical observation. They deny any intention of entangling themselves in " metaphysics," or concerning themselves with the " dreams of philosophers." But, despite their protestations, they do not adhere to their promise of confining themselves to the microscope, the X-ray, the clinical couch, and the questionnaire. The temptation to " philosophize" becomes too irresistible. Seeking to explain the individual " as a whole," they soon discover that there are certain things about man that are obviously a part of the "whole," yet which do not show up on the X-ray plates, the process of his thinking, for instance. So they begin to talk about those parts of man which they cannot see; they speak of his " mind " as something somehow distinct from his observable mental reactions. They observe that their patient does not always follow the course of action that various visceral pressures and nervous tensions would indicate that he is inclined to follow; so they begin to discuss his" will-power," as something different from his "physical" emotions. All this is against their thesis, for they started out with the premise that everything knowable about inan would yield to empirical observation. So they seek a way out of the dilemma. A loop-hole presents itself in the fact that there is obviously some sort of close relationship between a man's organic functions and his psychical reactions. They observe, for instance, that a pathological decrease in thyroid secretion is usually accompanied by a dulling of mental acumen, that an excessive secretion of adrenalin by the adrenal glands is conducive to increased emotional excitability. They "save EFFECT OF BODILY TEMPERAMENT 429 face " by proclaiming that thinking and willing, are functions of bodily organs, comparable to digestion, respiration or circulation, but functions which science has not yet advanced sufficiently to clearly analyze and determine. With better X-rays we will be able to photograph man's thoughts and feelings. We must look forward confidently to the day when more powerful microscopes will prove thought to be simply thinned out matter and the "soul" a mere product, perhaps, of radio-activity. Some of them maintain, apparently, that even now we have sufficient evidence to prove the complete materiality of man. Says Berman: One of the great achievements of modern science has been the release of thought from the theological dogma, even now accepted as gospel truth by hundreds of millions, that the personality consists of the manifestations of a "soul," a reality which is made up of " spirit," opposed in its nature and activities to " matter," and consequently to the "body " palpably flesh and blood. In the past the scientific attitude has done good destructive work and paved the way for more rational conceptions. Not until quite recently, however, has it substituted any really satisfactory and useful data for those it demolished" (i.e. the data of endocrinology) .3 Yet Dr. Berman is an authority on endocrine glands and will be quoted often in this paper as a reliable source of empirical endocrine data. Not all workers in the field have, however, gone to such extremes as the author of the above quotation. Many admit the existence in man of some sort of immaterial force, call it " soul " if you will, somehow distinguishable from his body. These have altered the propositum somewhat; they do not intend to formulate a complete explanation of the whole man from empirical data, but rather to explain as much of the whole as can be determined by empirical observation. Some too are restrained from extravagant conclusions by reason, no doubt, of their belief in a spiritual, immortal soul. Others seem to 8 Louis Berman, "Anthropology and the Endocrine Glands," Scientific Monthly, XXI (1925), 2. (By permission of the Editors, The Scientific Monthly.) 480 LEO M. BOND manifest a sort of groping attitude, as though they realize the need for solid principles to give support to their data. Perhaps the majority of the endocrinologists, if they are not already out and out materialists, at least show a definitely materialistic trend of mind, with all its ugly consequences. One reason for this is the fact that the data of endocrinology is peculiarly susceptible to materialistic interpretation, unless one is protected by true principles with regard to the nature of the soul and its powers, the nature of the body-soul union and the body-soul interdependence, a protection which most of the endocrine workers lack. It is evident that a knowledge and acceptance of sound principles would be of inestimable value to them. It would give a firm basis, direction, and orientation to their work and would render their research easier and more fruitful. H some of them do realize the need for such principles, they do not know where to turn. They are sceptical, because, as they say, history has shown that philosophies come and go; principles considered true to-day are discarded tomorrow. If each succeeding system of thought has been displaced by a subsequent one, how can any of them be depended upon? Such an attitude is, of course, based on the false assumption that all philosophies have been displaced by later ones, whereas only the false ones have failed to stand the test of time, precisely because they were false. One might suggest to them, of course, that the Aristotelian philosophy, for instance, has never been discarded, but only temporarily forgotten or misinterpreted or obscured by current false philosophies. Or one might mention to them the work of St. Thomas in the field of philosophy. Undoubtedly this would be dismissed as " religious "philosophy. H some were to become interested, they would probably smile when they came across some of the medical opinions of Aristotle and St. Thomas, not adverting to the fact, of course, that these men were not doctors of medicine but were merely basing their observations upon the medical opinions of the day, which though crude and now antiquated, were, nevertheless, the embryo from which modern medicine has developed, and were, EFFECT OF BODILY 481 in their broad outlines, not fundamentally different from the more refined doctrines of modern medical science. Nor do they realize that those opinions had a basis of truth sufficient for the rearing upon them of a sturdy edifice of true psychology, which, with the aid of careful introspection and logical reasoning, can and has been built up even from the data of common experience and common observation, having no essential need of the highly precise analyses and superfine calculations of modern medicine. As a matter of fact, the endocrinal theory of temperament exhibits a very notable fundamental similarity to the ancient-medieval theory of the " humors " as the chief determinant of individual somatic and psychical characteristics, and its proven data is particularly compatible with principles of Aristotelian-Thomistic psychology. It would seem of value, then, to point out the essential similarity of the psysiological bases upon which the two theories are built, with a view to establishing their compatibility from the viewpoint of psychology. This we will attempt to do in this paper. With this latter objective in mind, however, we will confine ourselves chiefly to that phase of the question with which psychology is most concerned, i. e. the influence exerted by · bodily temperament upon the psychical characteristics, treating the morphological aspects of the question only insofar as is necessary for an understanding of the endncrinal theory as a whole. Since bodily temperament may be considered, in both theories, as the point of departure for the determination of psychical differences, such a discussion will involve a step by step comparison between the two theories as to the nature and causes of temperament, the division of temperament into various "types" and the P:Sychical characteristics accompanying each type. We will then attempt to indicate how the principles of Aristotelian-Thomistic psychology render the endocrine data intelligible. The importance of such a subject is indicated by two facts: first, the great progress made in the study and knowledge of endocrinology in recent years, together with the great interest aroused as to its future possibilities, and, second, the tragic LEO M. BOND trend which the endocrinal theory of personality is taking in the field of psychology and ethics. As to the first fact, although endocrinologists admit that comparatively little is yet known about the function of endocrine glands, enough data has been established to arouse a feverish excitement as to the influence which the doctrine of the glands as the determinant of personality will exert upon education, sociology, eugenics, criminology, and morality. As Jane Stafford says, "With increased knowledge, interest in this subject has grown into a mighty crescendo till at the present time endocrine research is going on at a furious pace all over the world and with breath-taking results." 4 As to the second fact, even more "breath-taking" is the " philosophy " which some of the endocrinologists are spinning out of their clinical findings. The following quotations are an example of that strange confusion of fact and fiction which a lack of sound philosophical principles can beget. Mind, still regarded by most of mankind as something distinct and apart from the body, is thus exhibited as but part and parcel of it . . . . The sense organs of the body mediate the primary mind stuff. Without internal secretions and a vegetative system there could be no soul ... The internal secretions mediate the primary soul stuff. Mind is thus emulsified with body as a matter of cold literal fact. The soul was once a subtlety of metaphysics. Now, when mind appears soaked in matter saturated with chemicals like the hormones, therefore woven out of material threads, the independent entity created out of intangible spirit flies like a ghost at dawn. 5 Behavior may be defined as the resultant of the organism's pressure against the environment's counter pressure until there is a sufficient reduction of the specifically exciting intravisceral pressure. Just as water flows to its own level, so will conduct flow to reduce intravisceral pressure to its own level. A physics of the soul comes into prospect in which a mathematical analysis will state the process quantitatively in terms of some common unit of pressure. Not only conduct, but also character, because it is past conduct repeated, learned, and fixed, will be so statable. For intravisceral tonus or pressure is not simply or only an acute or passing affair.

EFFECT OF BODILY TEMPERAMENT 433 There is for it a persistent or average figure, the so-called normal for it, below which or above which the acute situation will bring it. Character becomes then a matter of standards in the vegetative system. Character, indeed, is created by different standard intravisceral pressures of the organism. 6 The poetic genius within him (man), as Blake called it, struggled on from one dogma concerning his nature to another. Behavior malignant or beneficial, horrible in its tragedy and pitiable in its comedy, flowed inevitably on. Witchcraft, trials, and ,the tortures of the Spanish Inquisition belong among the more mentionable consequences of some of man's theories about his own nature and its requirements. Heretofore the imaginative spirit has had its day in the matter. And, curiously enough, an obsession to subjugate the natural has made it exalt the supernatural. . . . But now for a couple of centuries the critical spirit, which is the spirit of science, has been invading the affairs of men. Humble but persistent corrosive of delusion, it has infiltrated the furthest bounds of ignorance and superstition. It has not dared to assert the supremacy of its fundamental views upon the everyday problems of human life because it was without concrete means of vindicating its claims. That lack is now supplied by the growing understanding of the chemical factors as the controllers and dictators of all the legion aspects of life. The profoundest achievement of the biochemist will be the change his teachings and discoveries will bring about in man's attitude toward himself. When he comes to realize himself as a chemical machine that can, within limits, be remodeled, overhauled and repaired, as an automobile can be, within limits, when he becomes saturated with the significance of his endocrine-vegetative system at every turn and move of his life, and when sympathy and pity informed by knowledge and understanding will come to regulate his relationships with the lowest and most despised of the men, women, and children about him, the era of the first real civilization will properly be said to be born. Morality, as society's code of conduct for its members, will change in the direction of a greater flexibility with the establishment of organic differences in human types. 7 All of which is very sad, and makes it clear how much the new " child of science," endocrinology, is destined to contribute to the already almost totally materialistic trend of modern • Ibid., p. 14!!. • Ibid., pp. 827-28. 434 LEO M. BOND thought, unless it can be saved from itself and put back on the right track. This is an accomplishment which would necessitate an acceptance by the endocrinologists of true principles of philosophy. Perhaps this is too much to be hoped for, at least until they themselves have learned, by experience, the necessity for such principles. But at least we can indicate certain points of contact, and point out certain lines along which the endocrinologists might be approached. That is all this paper professes to do. I. THE NATURE OF TEMPERAMENT 1. The Teaching of the Moderns. In common parlance, a " temperamental " person is one given to violent outbursts of emotion on slight provocation. The term has come to be associated with artists of various kinds, who are supposed to be emotionally unstable and highly excitable. Perhaps this popular notion has had some influence upon a large number of modern psychologists who conceive of temperament as the sum-total of a person's "affective" qualities (the "affective organization," as Bridges calls it, 8 "emotional traits and tendencies," according to Gates, 9 or "affective forms of action which depend on the co-operation of innate affective and volitional dispositions," according to Meumann) .10 Whether the popular notion of temperament has influenced the psychologists' conception of it or the psychologists' conception is responsible for the popular notion, both have two things in common: a placing of the emphasis on the observable psychical manifestations themselves rather than on any physiological substratum which might underlie these manifestations, and a confining of the term to emotional qualities, to the exclu8 James W. Bridges, An Outline of Abnormal Psychology (Columbus, 0., 1925), p. 117. • A. I. Gates, op. cit., pp. 518-19. 10 A. A. Roback, Psychology of Character (New York, 1927), p. 81. (Quotations from this work are printed by special permission of the publishers, Harcourt, Brace and Company, Inc.) EFFECT OF BODILY TEMPERAMENT 485 sion'-apparently, of intellectual qualities. As to the first point, such a view certainly represents a departure from the meaning of the Latin original of the word, temperamentum, which signifies a " mixture in due proportion," " the proper or natural quality of a thing, when it is not too great, not too cold, etc.," which reduces the term as it pertains to the human species to a physiological disposition. Though it is more or less generally admitted by the· moderns that individual psychical characteristics are in some way affected by physiological conditions, the term " temperament " is used by most of them to indicate the psychic characteristics themselves. This represents, in relation to the meaning of the Latin original of the word, an inversion of viewpoint. The proper primary meaning of the English word "temperament" is still, according to Webster, internal constitution with respect to balance or mixture of qualities or parts. As to the second point, the moderns' exclusion of intellectual qualities from the realm of influence exerted by temperament is from traditional notions, as we shall see later. Among the endocrinologists, there is, as already noted, an agreement that the constituent elements of empiriological personality are morphology, temperament, and character. They might also be said to agree, in general, that temperament, properly so-called, is the physiological disposition of the human body, viewed as the basis of all psychical characteristics, including intellectual, in which view they depart from the notions of perhaps the majority of modern psychologists. Pende, for instance, says " it is evident that we have no reason for making a sharp distinction between temperament and constitution, the former being simply the dynamic-humoral aspect of the latter," 11 which places temperament on a physiological level. The following passage might suggest, at first sight, that he considers temperament as something entirely unrelated to psychical qualities: 11 Nicola Pende, Constitutional Inadequacies, Translated from the Italian by Sante Naccarati (Philadelphia, 1928), p. 25. (Quotations from this work are printed by special permission of the publishers, Lea & Febiger.) 486 LEO M. BOND We may graphically represent the constitution as a triangular pyramid, the base of which encloses the patrimony of the individual's characteristics and the variations occuring during the evolutionary stages. From the base three faces rise with sides joined one to another, the morphological, the dynamic-humoral (temperament) and the psychological (character, intelligence). The synthesis of the three faces is the apex of the pyramid, that is the synthesis of the individual's vital properties, his resistance to his environment and his complete dynamic output.U But here he is simply stressing the fact that the term " temperament" applies properly and primarily to the physiological side of the constitution, but to the physiological side considered as the determining factor in all the individual psychical characteristics, for he says that the constitution . . . is governed by what we may term a correlational principle, according to which the various combinations of organs and organic fluids and the special relationships or anatomical and functional correlations between the parts of the body which determine the different physical and mental constitutions vary according to the characteristics that are dominant in the inter-organic equilibrium. Hence the two terms and concepts " constitution " and " temperament" are even now coupled together. The latter is still regarded as the dominant psycho-physiological note in a given individual, due to a predominance or deficiency of a function and, especially, of a humoral state, in the general dynamic balance .... 3 Hence temperament is for him the physiological make-up viewed from the aspect of its relation to the psychical make-up, of which it forms the basis. The characteristics considered in themselves, abstracting from their basis, constitutes the purely "psychological" side of the constitution, i.e. "character, intelligence," both of which are basically conditioned by the physiological temperament. Thus he does not exclude intellectual characteristics from the realm of temperament; they are the effects of temperament, along with all the other psychical characteristics. It is also clear how character is intimately connected with the constitution through the path of temperament. 12 Ibid., p. 18 Ibid., p. 18. EFFECT OF BODILY TEMPERAMENT 437 In view of the results of modern psycho-physiological investigation conducted along constitutional lines, we can no longer doubt that intelligence varies in quality as well as in degree in different individuals nor that it is related to the general constitution of the subject .... 14 Kretschmer, at one point in his book Physique and Character would apparently attach the term "temperament" to the " psycho- " end of the psycho-physiological apparatus, for he says: The temperament. It is as we know certainly from empirical observation, co-determined by the chemistry of the blood and the humors of the body. Its physical correlate is the brain-glandular apparatus. The temperament is that group of mental events which is correlated with the physical structure .... 15 However, at another point in the same book he admits that he has not decided at which end it belongs. He calls it a " heuristic " notion, i. e., one yet to be sufficiently investigated. "And finally the expression ' temperament ' has for us no welldefined meaning, but it is a heuristic notion, the breadth of whose field of reference we have not yet determined." 16 Nevertheless he proceeds to use the word as though he would indicate by· it that part of the psycho-physiological apparatus which influences the psychical qualities, which could be only their physical correlate, the "physical structure," according to his above quoted passage. The following quotation will exemplify this, and make clear the fact that he considers intellectual characteristics also as coming within the influence of temperament, together with all the other psychical qualities. The temperament, so far as our empirical investigations go, has a clear influence on the following psychic qualities: (I) On the psychaesthesia, abnormal sensitivity or insensitivity to psychic stimulation; (2) on the mood-coloring, the pleasure or pain coloring of the psychic content, particularly on the scale which lies between gay Ibid., p. 25.

BOND and sorrowful; (3) on the' psychic tempo, the acceleration or retardation of the psychic processes in general, as regards their particular rhythm (tenaciously holding back, suddenly darting forward, inhibition, formation of complexes); (4) on the psychomotility; on the general movement-tempo (mobile or comfortable) as well as on the special character of psychic activity (lame, stiff, hasty, vigorous, smooth, rounded, etc.) In addition it may be empirically established that the forces which influence all these factors play an important part in the determination of the types of perception and imagination, in what is called intelligence or mental disposition. . . Y His conception of " character " is practically the same as Pende's, i. e. the sum-total of an individual's psychical qualities considered in themselves, abstracting from their " bodily correlates " or physiological basis. He would include in character, however, certain modification brought about in the innate psychical characteristics by such external influences as education, environment, etc. The notion of " constitution " is essentially psycho-physical, and general-biological and has to do with the interrelations of body and mind. The concept of " character," however, is a purely psychological one. By " character" we understand the totality of all possibilities of affective and voluntary reaction of any given individual, as they come out in the course of his development, that is to say what he inherits plus the following exogenous factors: bodily influence, psychic education, milieu, and experience. By " character " we understand the totality of all possibilities of affective and voluntary reaction of any given individual, as they come out in the course of his development, that is to say what he inherits plus the following exogenous factors: bodily influence, psychic education, milieu, and experience. The expression " character " lays the accent on the affective side of the total personality, without, of course, the intelligence being separated from it at any given point. The notion of "character" has a great deal in common with the notion of constitution, namely such psychic qualities as are inherited; it eliminates, however, the bodily correlates, which the notion of constitution includes, while on the other hand it includes exogenous factors, the result of 17 Ibid., pp. EFFECT OF BODILY TEMPERAMENT 439 education and environment in particular, as important elements, which are left out of the notion of constitution. Outside this exactly defined sphere of reference one can use the expression " character '' for the general structure of the personality, without laying any particular stress on the differences between constitutional factors and those which are exogenously developed. 18 Here again, by eliminating the " bodily correlates " from " character," and yet including them in " constitution," which is " essentially psychophysical," he leaves no other " field of reference " for temperament but the " bodily correlates " themselves. This, no doubt, is what Dr. Strauss has in mind when he says, in the introduction to Aller's "Psychology of Character," "in my opinion, his (Kretschmer's, great work " Physique and Character," should rather have been entitled " Temperament and Character." 19 The French School has done away with all discussions as to what they mean by " temperament " by simply substituting for it the term " constitution," constitution being for them the general physiological condition resulting from the predominance of some particular system in the organism and serving as a basis for individual psychical characteristics. As Roback says: Rostan, following the line of this systematic school to its logical conclusion, substituted the term " constitution " for that of " temperament " and derived his six kinds of constitutions from the predominance of the various systems in the economy of the organism. 20 In emphasizing the predominance of some one physiological system in the development of the organism as a basis of classification of types, Sigaud of course made no departure from his predecessors in France who had adopted the term " constitution " to replace the word "temperament" .... 21 There can be no question, then, as to where this school places the emphasis in the signification of " temperament," namely, on the physiological basis of psychical characteristics rather Ibid., pp. fl58-59. R. Allers, Psychology of Character (New York, 1939), Int. 21 Ibid., p. 89. 20 Roback, op. cit., p. 58, 18 19 440 LEO M. BOND than on the characteristics themselves. Nor do they exclude intellectual qualities as resultants of this basis, for in describing the psychical "types" of individuals corresponding to the various constitutions or temperaments, they include intellectual as well as affective characteristics. From all this, then, we might formulate a definition of temperament which would represent, basically, the general notion of that group of scientists whom we have classified under the general designation of " endocrinologists," by saying that temperament is the innate, characteristic, physiological structure and functional disposition of certain bodily organs and tissues, regarded particularly from the viewpoint of the influence which such structure and disposition exert upon the characteristic sensational, emotional, intellectual and volitional reactions of an individual throughout life, as well as upon his somatic or morphological characteristics. We say "innate" rather than "hereditary" structure and functional disposition, for while the endocrinologists frequently use the term" hereditary" in a broad sense, geneticists limit it to those characteristics which an individual receives from his ancestors at the time of conception, through the chromosomal genes, whereas " innate " includes various modifications of the embryonic organs not due to " heredity " in the technical sense of the word, but resulting rather from intra-uterine influences such as inadequate or excessive supply of various formative and nutritive substances by the body of the mother, pre-natal accidents, disadvantages arising from the simultaneous presence of other fetuses in the. womb, general intra-uterine environment, etc., all of which might profoundly influence an individual's entire physiological and psychical future. By the word " characteristic," in both places in the definition, is meant "characteristic of the individual" rather than of the species, for while it is presupposed that all human beings have specifically the same physiological and psychical constitutionallowing, of course, in the physiological order, for the differences due to sex-it is generally held that no two individuals are ever born with exactly the same condition of their physio- EFFECT OF BODILY TEMPERAMENT 441 logical and psychical constitution, not even identical twins, although they are presumed to have received exactly the same kind of genes and to have been subject to approximately the same intra-uterine influences. Moreover, we say " certain " organs and tissues, for while there is a growing tendency among modern biologists, psychologists, etc., to consider all the bodily structures as in some way contributing to psychical characteristics, little evidence has been produced to show that this is true, whereas the effect of the condition of such organs as the brain, the nervous system, the endocrine glands, etc., upon the psychical activities has been well established. Under "organs" we include not only the organs themselves but the fluid media in which many of them are immersed and which are essential to their normal functioning, as well, of course, as the fluids contained within some of the organs as an essential part of them, as, for instance, the spinal fluid of the nervous system, the interstitial brain fluids, etc. Under "tissues " we include the blood, following many leading medical authorities. By "sensational" reactions we refer here chiefly to cognitive reactions of the internal senses, for while the condition of the external sense organs may be considered, to some degree, as a phase of temperamental disposition, the reactions of the external senses cannot properly be called " psychical " until perception takes place, which involves the internal senses. " sensational reactions " refers, therefore, chiefly to an individual's better or worse powers of memory, imagination, common sense, etc. By characteristic " intellectual " reactions is meant primarily an individual's innate qualities of intellect, better or worse as the case may be, insofar as they can be judged from the quality of its functions. We might also include under characteristic intellectual reactions, the possibly innate aptitude for particular kinds of mental activity, speculative, practical, scientific, and artistic, although little is known as to the influence, if any, of physiological dispositions on particular intellectual talents. 4 442 LEO M. BOND Characteristic " volitional " reactions refers chiefly to strength or weakness of will, tendency of individual wills to choose certain kinds of particular goods in preference to others. The phrase " throughout life " in the definition is very significant. Innate structural and functional peculiarities of organs and tissues are more or less only "potential" at the time of birth, i. e. they are tendencies inherent in the embryonic organs which destine them for development, under normal conditions, along certain predetermined lines. The organic modifications attendant upon the advent of puberty, maturity and senescence and, in women, of pregnancy, child-birth and menopause, may be merely as phases of this normal predetermined development. But any number of accidental circumstances and events may come about throughout life which will profoundly interfere with the normal condition and functioning of the organism. Physical environment '(food, climate, etc.) , diseases, accidents, may effect temporary or even permanent changes in the physiological economy, but only down to the level of and in proportion to the basic, innate, more or less permanent organic structure and disposition. Temperament, properly speaking, is confined to the basic, inborn structure and dispositional qualities of the organism and abstracts from the temporary or even permanent permutations brought about in the course of life by accidental circumstances. Strictly, the only change which temperament undergoes is that connected with the normal development and decline of the organism throughout the life span. The same is true to some extent of the psychical characteristics correlated with the bodily temperament, i. e., they are only " potentialities " at birth, differing in degree with each individual born and destined for a normal development along certain lines, within the limits set by the basic physiology. Throughout life, these characteristics are subject, even more so, perhaps, than are the physical organs, to countless changes and modifications arising from both internal influences such as pathological changes in the body, personal effort, ·volitional control, etc., and external influences such as psychical environ- EFFECT OF BODILY TEMPERAMENT 443 ment, education, opportunity, occupation, but again even here ordinarily only down to the level of and in proportion to the basic temperament. These changes in the psychical characteristics themselves pertain more to character than to temperament, since character, as the endocrinologists conceive it, is, as we have seen, the complexus of individual psychical qualities themselves at any given point in life, resulting from the bodily temperament plus modifications introduced by both internal and external influences. Character so considered might be called psychological character, as distinguished, to some extent, from moral character. Moral character introduces elements extraneous to character considered as a purely psychological entity. It involves the conformity or non-conformity of psychical acts to norms of morality, the cultivation of vices and virtues, etc., all of which involve partially exogenous influences brought to bear upon the native psychical characteristics but which do, nevertheless, affect these characteristics even from a purely psychological aspect. Thus, moral character, while under some aspects distinguishable from psychological character, is, nevertheless, intimately connected with it and, like psychological character, is correlated to some extent with the physiological temperament. A person, for instance, who is especially prone to incontinence or anger by reason of his characteristic physiological and psychical make-up will have much more difficulty, and, in the supernatural order, will require more grace, in practicing the virtues of chastity and meekness than will the individual who is not so inclined physiologically and psychically. Also " fixations," " complexes," " inhibitions," etc., to use modern terminology, resulting from any number of physiological and psychical conditions even in what are considered normal persons, may exert a very definite influence upon moral character. In this paper, however, we will confine" character" to its purely psychological aspect. Moreover when we speak of the " psychical characteristics of temperament," we refer to those individual characteristic ways of reacting psychically to which a person is prone by reason of his bodily temperament, 444 LEO M. BOND without implying, as some of the endocrinologists do, that he always or of necessity must so react. We have concluded the definition of temperament with the phrase " as well as upon his somatic or morphological characteristics," for while we have excluded this aspect of temperament from our present discussion and have therefore not considered the endocrinologists' notions of this phase of temperament, nevertheless it might be said that in general most of them consider the characteristic morphological structure of an individual as also resulting from his temperamental pattern, i. e. from the innate structure and functional disposition of certain organs and tissues, in such a way that individuals endowed with a particular group of psychical characteristics will generally have also, they say, a corresponding somatic make-up as to height, weight, bone structure, etc. This aspect of temperament has been stressed particularly by Kretschmer. However this phase of temperament pertains more to medicine and anthropology than to psychology. Finally, we have said in the definition that temperament is the physiological disposition " particularly " from the viewpoint of its effect on the psychical and morphological characteristics, because the same structure and functional disposition of the organs and tissues that affects these characteristics also frequently produces tendencies towards certain diseases. Consequently some endocrinologists speak of such tendencies as also coming from "temperament"; usually, however, the term is not employed in connection with this aspect of human physiology, but only in relation to psychical characteristics. Few of the endocrinologists admit all of the distinctions or use all of the terms we have employed in enumerating psychical activities. Nevertheless, this is, in scholastic language, fundamentally what they mean in their language. The possibilities of mutual influence and interplay among all these reactions of which we have been speaking, involving as they do the as yet comparatively little known intricacies of the human body as well as the unfathomed complexities of the human soul, make it evident that the question of temperament EFFECT OF BODILY TEMPERAMENT 445 is anything but a simple one. It involves matters that have been perplexing great minds for centuries and only a few of the greatest minds in history have succeded in unraveling some of its mysteries. The most important point with regard to the endocrinologists' ideas of the nature of temperament is, at the present stage of our consideration, the fact that they consider temperament as the physiological basis of all the individual psychical characteristics, including the intellectual, in which they depart from the views held by perhaps the majority of modern psychologists. 2. The Teaching of Aristotle and St. Thomas. That Aristotle and St. Thomas considered temperament a matter of the structure and functional disposition of the bodily organs themselves, is evident from the fact that they accepted the theory current in their respective days as to the composition of human bodies. In the following chapter we will consider this theory more in detail. Substantially it was this: the human body was derived, ultimately, from the four inorganic elements -earth, fire, air, and water. The process was as follows: from the mixture of the four elements were generated four humorsthe blood, the phlegma or pituita, the bile or cholera, and the atra-bile or melancholia which were the primary· organic compounds. In the humors the four elements remained only virtually, by reason of their respective qualities, i.e., the coldness of the earth, the warmth of the fire, the dryness of the air, and the wetness of the water. In each humor were various combinations of these qualities. The blood was warm and moist; the phlegma, cold and moist; the bile, warm and dry; the atra-bile, cold and dry. The four humors combined to form various types of organic tissue, such as bone, nerve, and muscle; and these various types of tissue combined to form the particular organs required by the human body. In the organs, the four qualities derived from the humors were in more or less of an equilibrium. The more closely this equilibrium approached perfect evenness, the better would be the structure and functional disposition of the bodily organs, and consequently, of the body as a whole. 446 LEO M. BOND Once the body was formed and the organs functioning, the liver manufactured the four humors from the digested food.22 These were carried by the blood, itself one of the humors, to all the parts of the body, and were absorbed from the blood stream by the various organs, for their nutrition. While in the organs of the human body the equilibrium of the humoral qualities was, in general, much more even than in the ·bodies of animals, within the human species the degree of equilibrium varied with each individual according to the predominance in his cold blood of one of the four humors, which would affect the equilibrium in his organs and consequently their structure and functional disposition, which would thus vary in different individuals. For the equilibrium of the four humoral qualities in the bodily organs and the organic disposition resulting therefrom, the Latin writers used the word complexio, which means, primarily, " a close conjunction, " and secondarily " a habit of body." They preferred complexio to temperamentum, probably because it was closer to the Greek. T emperamentum means primarily "mixture in due proportion" and secondarily, "the proper or natural quality of a thing when it has its proper measure," and therefore expresses the same idea contained in complexio, according to the above described theory. Early English translators of the Latin writers, however, rendered complexio sometimes into "temperament," sometimes into "complexion," but usually into " temperament," when it was a question of human ·bodies. The same is done by the best modern translators, e. g. in the English rendition of St. Thomas' Summa Theologica and Summa Contra Gentiles, by the English Dominicans. In translating passages from Latin works, therefore, we will render complexio as " temperament." For passages from the two Summas of St. Thomas, we will use the translations of the English Dominicans. That St. Thomas, following Aristotle, accepted the theory of physiological composition of bodies described above and conn Hippocrates (B. C. 859?) thought that the blood was produced in the heart; the phlegma; in the head; the atra-bile, in the spleen; the bile, in the liver. After Galen (A. D. 200?), the liver was considered the factory of all the humors. EFFECT OF BODILY TEMPERAMENT 447 sidered temperament as the disposition of bodily organs, differing with different individuals, can be seen in the following passages, a few among many: Whence it is apparent that the whole activity of inferior nature terminates in man as its most perfect being. For we see that the operation of nature proceeds gradually from simple elements, by mixing them, until it arrives at the most perfect kind of mixture which is in the human body. 23 There is one kind of humidity which has some definite form according to which it is included among the parts of the body, as are blood and the other three humors, which nature has ordained to the members, which are generated from them. 24 To the third objection, I say that just as the elements are on the way to generating with respect to mixed bodies, since they are their matter, not however, in such a way that they are always in a state of transition in the mixed body, so also are the humors in relation to the members. 25 For touch perceives those things of which it is necessary that the animal body be composed, namely, heat, cold, moistness and dryness. 26 Seeing that the temperament is something set up by contrary qualities as a kind of mean between them, it cannot possibly be a substantial form; because substance has no contrary, nor is it a recipient of more or less. 27 A body is not necessary to the intellectual soul by reason of its intellectual operation considered as such; but on account of the sensitive power, which requires an organ of equable temperament. Therefore the intellectual soul had to be united to such a body and not to a simple element, or to a mixed body in which fire was in excess; because otherwise there could not be an equability of temperament. And this body of an equable temperament has a dignity of its own by reason of its being remote from contraries. 28 This therefore must be the disposition of the body to which the rational soul is united, namely that it should be of the most even temperament. 29 For there is a certain natural disposition demanded by the human species, so that no man can be without it. And this disposition is natural in respect of the specific nature. But since such a disposition •• Q. D. De Anima, a. 8. .. IV Sent., d. xliv, q. I, a. !'l. •• Ibid. •• De Anima, loc. cit. Summa Contra Gentiles, II, bciii. Summa Theol., I, q. lxxvi, a. 5, ad !'lum. 29 De Anima., loc. cit. 27 28 448 LEO M. BOND has a certain latitude, it happens that different grades of this disposition are becoming to different men in respect of the individual nature. 30 It is not possible that the diversity of souls be explained in the same way we explain the different degrees of the angelic nature, since all the rational souls are of the same species, and do not differ except numerically. Now all such diversity comes from matter and therefore since the soul does not contain intrinsically any matter, it is necessary that the diversity and distinction of souls be caused by the diversity of their bodies; so that as the temperament of the body would be more perfect, a more noble soul would be imparted to it, since everything is received according to the disposition of the receiver. 31 For mixture, the activity of active and passive qualities is required; and according to the predominance of one or the other, mixed bodies have a different temperament; which must be said of the body. 32 To define temperament as the disposition of bodily organs particularly from the viewpoint of the effect on the individual psychical and morphological characteristics is somewhat of a concession to the modern acceptation of the word. The older writers used the word complexio to signify the disposition of the organs in themselves without regard to any particular viewpoint. But most frequently, perhaps, it was used in connection with psychical characteristics. The point of interest is that the older writers did actually consider complexio as having a determining effect upon the individual psychical characteristics, and as being the dispositive cause of all such characteristics, intellectual as well as sensitive. That St. Thomas, following Aristotle, considered it as such is apparent from the following passages, again, only a few among many. Later we shall consider some of St. Thomas' ideas as to the effect of particular types of temperament upon psychical characteristics; here we will glance at his more general views. In general, all individual psychical dispositions depended upon the individual bodily disposition: " . . . the diverse dispositions of men toward the operations of the soul come from 30 31 Summa Theol., I-II, q. li. a. I. II Sent., d. xxxii, q. II, a. 3. 32 IV Sent., d. xliv, q. II, a. 1. EFFECT OF BODILY TEMPERAMENT 449 the diverse disposition of the body." More in particular, the perfection of the whole sensitive nature depended upon the perfection of the temperament, by the following process of reasoning. Since touch is the foundation of all the other senses, the perfection of the whole sensitive nature depends upon the perfection of touch. " While there are many senses, there is one, however, which is the foundation of the others, namely, touch, in which the whole sensitive nature principally consists." 84 " Hence from the fact that one has a better sense of touch, it follows that he has in general a better sensitive nature." 35 But the perfection of touch depends upon the equability or perfection of temperament. " Goodness of touch depends upon the equability of the temperament." 36 Therefore the perfection of the whole sensitive nature depends upon the perfection of temperament. The quality of the internal senses depended upon the temperamental disposition of the brain: " . . . for the good quality of the internal sense faculties such as imagination, memory and the cogitative power, a good disposition of the brain is necessary." 37 The characteristic affective or emotional tendencies flowed, on the material side, from the individual temperament: " . . . by temperament, some are more prone than others to desire or anger." 38 For they (the passions) are ascribed to the temperament as causing a disposition, and in respect of that which is material in the passions, for instance the heat of the blood and the like. 39 And if we consider the nature of the individual, in respect to his particular temperament, thus anger is more natural than desire; for the reason that anger is prone to ensue from the natural tendency to anger, more than desire, or any other passion, is to ensue from a natural tendency to desire, which tendencies result from a man's individual temperament. 40 But on the part of the body, in respect of the individual nature, there are some appetitive habits by way of natural beginnings.

BOND some are disposed from their own bodily temperament to chastity or meekness or suchlikeY The intellectual qualities characteristic of an individual depended upon the better or worse dispositions of his internal senses, which in turn depended upon his individual bodily temperament: Experience shows that some understand more profoundly than do others; as one who carries a conclusion to its first principles and ultimate causes understands it better than the one who reduces it only to its proximate causes. 42 The understanding of principles results from man's very nature, which is equally shared by afl. Nevertheless the truth of principles is more known to one than to another, according to the greater capacity of intellect. 43 . . . and the fact that men understand unequally comes from the diversity of the sensitive faculties from which the species are abstracted; and this likewise comes from the diverse disposition of bodies. 44 . . . men are observed to be more or less apt for the considerations of sciences according to the various dispositions of the cogitative and imaginative powers. But this aptitude depends on these powers as on remote dispositions, in the same way as it depends on perfection of touch and bodily . . . the diversity of temperaments causes a better or less good faculty of understanding by reason of the faculties from which the intellect abstracts; which are faculties using corporal organs, as imagination, memory and the like. 46 ... thus because some men have bodies of better disposition, their souls have a greater power of understanding ... for those in whom imaginative, cogitative and memorative powers are of better disposition, are better disposed to understand. 47 . . . and thus, physicians are able to judge of a man's intelligence from his bodily temperament, as a proximate disposition thereto. 47 " *'Ibid., q. 51, a. 6. •• Summa Theol., I, q. 84, a. 7. •• Ibid., q. 98, a. 1.

EFFECT OF BODILY TEMPERAMENT 451 As to individual volitional characteristics, since according to St. Thomas the will is simply the appetitive quality of the intellect, it would follow that volitional qualities would also be influenced to some degree by the intellectual qualities; hence also by the sensitive and affective dispositions, hence by the individual temperament. Most of the above expressed ideas of St. Thomas were based upon the doctrines of Aristotle, of which we will see more later. Hence it is clear that for both Aristotle and St. Thomas temperament was the innate, characteristic structure and functional disposition of the bodily organs and tissues and that this disposition, differing in different men, exercised a profound determining effect upon all the characteristic sensational, emotional, intellectual and volitional qualities of an individual. That they also considered morphological characteristics as stemming from the individual temperament follows from their notions as to the effect of complexio upon the bone structures, limbs, etc., and passages may be found in their writings dealing with this aspect of temperament. For the complexus of psychical characteristics considered in themselves, the older writers used no one word such as "character," but spoke simply of better or worse powers of imagining, remembering, understanding, different dispositions in the faculties of the soul, etc. It is evident, then, that the notions as to the nature of temperament presented in recent years by the endocrinologists are by no means new " discoveries of science," but merely represent a return to the fundamental ideas of ancient and medieval scholars such as Aristotle and St. Thomas, with whom they are, at least basically, in close accord on this point. II. THE CAUSES OF TEMPERAMENT In a sense, the above title is, to say the least, a presumptuous one. If temperament is a matter of the structure and functional disposition of the organs of the human body as they affect psychical characteristics, and if by" causes" we have in mind a complete synthesis of all the material, formal, efficient and 452 LEO M. BOND final causes, to answer adequately the question," What are the causes of temperament? " would be a feat requiring the combined efforts of all the disciplines of chemistry, biology, anatomy, medicine, philosophy, and, for that matter, theology. If we restrict the question to its purely chemical and biological aspect and ask," What is the exact chemical formula of each of the bodily organs, what are all the functions of each and how and why and when does each one function? " we would be asking something about which even these sciences know comparatively little. If we limit the enquiry still further and ask, "What are the chief chemical and biological factors in the differentiation of one individual's physiological and psychical make-up from that of another?" we are restricting the issue somewhat but at the same time greatly complicating it by extending our enquiry to the psychological aspects of the question. But if we ask this same question, as we must, from the viewpoint of chemistry, biology and psychology, the answer would have to be somewhat along these lines: " There are probably many such factors. Some are fairly demonstrable, others much less so: some are only suspected and still others perhaps, which are as yet completely unknown." Of the " fairly demonstrable " group we might ask, " Which, if any, is the factor that empirical investigation has indicated as probably the most influential single physiological faetor in the differentiation of individual organic dispositions as they affect individual psychical characteristics?" To this question the endocrinologists answersome confidently, some hesitatingly-" The secretions of the endocrine glands." To the same question, the ancients and medievalists answered, centuries ago, " The four humors of the body." A consideration of these respective answers forms the subject matter of the present discussion and indicates the sense in which its title is to be taken. 1. The Teaching of the Endocrinologists. A gland is defined by Wolfe as " an aggregate of cells which has for its purpose the transformation of substances abstracted from the surrounding blood or lymph, into specific compounds, EFFECT OF BODILY TEMPERAMENT 458 generally useful in allowing some part of the body to perform one or more functions adequately." 48 Glands are of two kinds: duct glands, which dispose of the compounds they have manufactured by pouring them out onto some body surface by way of a duct; and ductless or endocrine glands, which deliver their manufactured secretions directly into the blood stream, or the lymph, which distribute them to the bodily organs as they are needed. Examples of duct glands are the sweat glands, secreting perspiration, and the lachrymal glands, manufacturing tears. The principle ductless or endocrine glands, also called glands of internal secretion (hence the name " endocrine," from the Greek "endo " (within) , and "krenein" (to separate), are the pituitary, located on the undersurface of the brain; the thyroid, situated in the lowermost portion of the anterior neck; the parathyroids, immediately behind and connected with the thyroid; the pancreas, in the abdomen, close to the posterior wall; the adrenals, just above the kidneys; and the gonads, in the sexual organs. (These last, the gonads, in addition to their endocrine function have also a duct gland function required for reproduction. The pancreas also elaborates an external secretion, the pancreatic juice.) There are a number of other glands about whose classification as " endocrines " authorities disagree, since little is known about their precise secreting function. Of these we will see more later. The particular functions of some of the major endocrine glands we will discuss more in detail. Here we will simply note some general aspects of their function. Each endocrine gland elaborates at least one secretion; some, e. g., the pituitary and the gonads, elaborate several different secretions. While a particular name has been assigned to most of the endocrine secretions, the generic name applied to all of them is " hormone," a term proposed by two English physiologists, Bayless and Starling, in 1902. The term was accepted by the medical profession as most descriptive of the general •• William Wolfe, M.D., Endocrinology in Modern Practice (Philadelphia, 1939), p. 18. (Quotations from this work are printed by special permission of the publishers, W. B. Saunders Company.) 454 LEO M. BOND function of the endocrine secretions, which is to set in motion and regulate the functioning of all the cells, tissues, and organs of the body by stimulating their proper activity here or retarding it there, as necessity demands, thus maintaining a proper balance or coordination among the functions of all the various parts of the organism. As Dr. Wolfe says: In the body the different degrees of life activity and capacity for work of the various cells can be utilized only if a carefully planned system of controlling influences accelerates activity here and retards it there thus keeping the machinery running smoothly. It is true that the individual organs are capable of independent life and action of their own, as seen in experimentally extirpated tissues. A human being is not, however, a conglomeration of organs but an intricate system of interactions between these components, each supplying certain needs to the others. It is the endocrine glands which are charged with the task of coordinating the speed with which every cell in the body performs its duty. These little organs can sense any change of environment which requires tissue response, and they react immediately by sending out impulses or hormones to the appropriate organs whose functions must be accelerated. The hormone reaches a specific tissue and there assists in the occurranee of certain biochemical or biological phenomena. 49 Thus the hormones, which are themselves chemical compounds, perform their regulating and balancing function by stimulating "chemical changes in all the cells of the body." 50 Hence their influence is widespread and dominant. " The products of each gland are taken up directly by the circulation and carried to all the parts of the body where they exert specific influences upon all its structures and most of its functions." 51 " Their effects are so widespread that no organ or even part of an organ can escape their dominating influence." 52 They "influence the vital and fundamental processes of life such as reproduction, growth and metabolism." 53 •• Ibid., p. 19. •• Samuel A. Loewenberg, M.D., Clinical Endocrinology (Philadelphia, 1941), p. 821. (Quotations from this work are printed by special permission of the publishers, F. A. Davis Company.) 61 Ibid., p. 19. "" Wolfe, op. cit., p. 15. •• Loewenberg, op. cit., p. 18. EFFECT OF BODILY TEMPERAMENT 455 It is chiefly through their control of the metabolic processes that the hormones affect the structural disposition of the organs, since it is by reason of metabolic activity that the various cells, tissues, and organs are enabled to assimilate properly the nutrient elements essential to their formation and determinative of their structure and growth, both in utero and throughout life. It is in the intra-uterine formative stages that the hormones exert their greatest influence upon the innate structure of the organs and tissues upon which their whole physiological future depends to a great extent. As Berman says: . . . . . . We know that the endocrines rule over growth and nutrition, a vast dominion which incorporates every organ and every tissue. By enhancing or retarding the nutritional changes, the growth of the organ or tissue is favored or restricted. 54 ... undoubtedly they (the endocrine secretions), initiate the marvelous unfolding of tissues and functions, organs, and faculties summed up as development or differentiation. 55 In their ensemble, the glands of internal secretion wield a determining influence upon the development of the individual from his very inception. If his various powers may be conceived of as an orchestra, they may be said to conduct it from the very beginning of its movements, and to cease only with its termination. From the moment when the spermatozoon penetrates and fecundates the ovum, the fate of the future being is settled by their disposition. The seal of his destiny is soaked with their substance. They act before he is born as well as after. 56 Every human body starts out as a single cell, the fertilized ovum, capable of carrying on in itself all the processes necessary for its continued existence and reproduction. This single cell divides and becomes two cells; each one of which again divides into two more cells, and so on. As this process of division and multiplication continues, the groups of cells ... organize themselves in such a manner that they delegate certain activities to other cells, assuming in exchange the burden of •• Berman, op. cit., p. 161. •• Ibid., pp. 59-60. 18 Ibid., p. 147. 456 LEO M. BOND carrying out other functions for their coworkers. This process of specialization continues to a greater and greater extent, until all the cells lose their capacity to carry on certain of the activities essential to life, but become infinitely more efficient in others. They lose their capability of independent existence, although potentially they are still endowed with all the attributes necessary for independent life.57 In this way, the various organs and tissues of the body are formed from the numerous cell groups and when sufficiently formed, begin to carry on their own individual functioning. This process is controlled and influenced to a great extent by the amount and quality of the nutriment received from the mother's body by osmosis or absorption through the wall of the uterus and passed to the embryo through the umbilical cord by which it is attached to the placenta. The quantity and quality of the endocrine secretions received by the embryo from the mother's body exert a dominant influence on the multiplying and group-organizing activities of the cells and upon the formation of the embryonic organs. Any undue over- or undersupply of any of these secretions has a profound effect upon the cellular activity and thus upon the structures of the cells and organs formed thereby, especially upon the formation of the endocrine glands of the embryo itself. When these latter have reached the functioning stage, their future has already been determined to a great extent not only by the predispositions inherited from the parents through the genes, but also by the amount and quality of the secretions received from the mother's body after conception. When the first endocrine glands of the fetus begin to function, they themselves commence to exercise a determining influence upon the other embryonic glands, organs, and tissues. It is easy to see here the important role played by the hormones in the determination of the peculiar organic structure and functional dispositions characteristic of an individual. It is particularly at this stage that, according to the endocrinologists, the various physiological " types " are determined, chiefly by an over- or undersupply of 67 Wolfe, op. cit., pp. 18-19. EFFECT OF BODILY TEMPERAMENT 457 one. or more particular hormones, with its resulting effect upon the physical characteristics of the whole organism. The thyroid, for instance. . . . determines the embryonic etchings of the different organs which in their totality comprise the unique and individual. Every human being, like every multicellular animal, must first have existed as a single cell, the impregnated ovum. With the body and personality of the ovum, the creature is one and continuous, literally something the single cell has made of itself by subdividing and differentiating . . . we know that there is an orderly progression of events, a propagation of cells, a forward going arrangement of chemical reactions that results in expansion and intricate complication of the organism. 58 A vast number of observations gathered by laboratory experimentalists as well as by those naturalists of the abnormal, physicians in active practice, prove that the construction of the individual both during development before maturity, and maintenance during maturity, his constitution, in short, is directed by the endocrine glands. It is possible now to present an explanation of the individuality of the individual. To assert that variation is responsible for the individual, that it is the mechanism which isolates him as a being like none other of his fellows, not even his parents, brothers and sisters, is merely to beg the question. What is variation? The internal secretion theory of certain variants is an explanation that is coherent and comprehensive, based upon concrete and detailed observations. It provides an adequate interpretation of numberless hereditary gradations and transitions, blendings and mixtures. In the pure types, only one gland, either by being present in great excess above the average, or by being pretty well below the average, comes to exercise the dominating influence upon the traits of the organism. As the strongest link in the chain, or as the weakest, it rules. The others must accommodate themselves to it. Among them as commanders of growth, development, and normal function, it holds the balance of power. In every emergency it stands out by its strength or by its weakness. It thus creates its own types of man or woman, with attributes and characteristics peculiar to itself. 59 The endocrine system as a whole is a very complicated affair. Beside the manifold functions of each gland and each hormone, •• Berman, op. cit., pp. 59-60. 5 •• Ibid., pp. 148-149. 458 LEO M. BOND there is an intricate interplay between the hormones of one gland and those of another. Some are synergistic to others, some antagonistic; some accelerate the activity of others, some retard it; some compensate for the deficiency of others, etc., so that an almost infinite number of combinations, " blendings and mixtures," are possible. Hence while one gland may dominate an individual's physiology and determine his "type," nevertheless, within each " type " countless degrees and gradations are possible, even within the range of " normal." Moreover the " pure types " spoken of by Berman, are actually rarely found. Most individuals represent a combination of various types, due most probably to the relative predominance of several glands in their physiological economy. However, in each individual there is usually a sufficient predominance of the characteristics of one type to enable trained observers to determine his position in the type categories. The study of the glands of internal secretion, then, has led the endocrinologists to the conclusion that these glands, taken as a whole, are in all probability the most influential single factor in the determination of physiological individuality. That this physiological individuality is the basis of psychical individuality is a conclusion that has been more or less forced upon them by observation of the effects produced by the endocrine secretions on the psychical characteristics. These effects have been noted especially in endocrine pathologies where an abnormal under- or oversecretion of some particular hormone, due to congenital malfunction of the gland, gland infection, tumors, injuries, etc., has been accompanied by notable changes in psychical qualities. In confirmation of these observations innumerable experiments have been performed on both animals and human beings, in which injections of hormones, natural or synthetically manufactured, partial removal or transplantation of various glands, etc., have been found to produce psychical effects similar to those noted in endocrine malfunctions. From these observations in abnormal conditions, the endocrinologists have been led to the observation of variations in the psychical characteristics of " normal " individuals, resulting from normal EFFECT OF BODILY TEMPERAMENT 459 variations of secretion, for as Berman says, " The difference between normal and abnormal is only a matter of degree." Pende thus sums up the general means whereby these empirical data have been accumulated and applied to normal temperaments. We shall now briefly point out these various endocrine temperaments, which have been discovered for the most part by the constitutional study of endocrinopathic subjects in the period that preceded the appearance of definite glandular disease and in the period that followed its apparent clinical cure; also by the study of endocrinopathies whose families have members with all degrees of functional change of the same endocrine gland as that which is affected in the patient; by the study of hyperfunctional or hypofunctional symptoms presented by the endocrine glands under certain physiological conditions of the organism which demand greater work from certain glands, as happens at puberty, during pregnancy, in the menstrual cycle and at the menopause, under which conditions various hypoendocrine or hyperendocrine temperaments are easily revealed. Finally, these different endocrine temperaments are shown by the comparative study of the morphological and functional signs of certain constitutions, with manifestations that can be experimentally and clinically provoked by the administration of glandular extracts or by the partial functional suppression of the endocrine glands. 60 We might note, at this point, that one of the most important media through which the endocrine secretions have been found to affect the psychical qualities is the nervous system. In other words, psychical individuality, in many of its phases, has been found to be closely correlated with the individual, characteristic structure and functional dispositions of the nervous system in general, which dispositions, in tum, have been conditioned largely by the-endocrine glands, both in the formative stages in the embryo and in the post-natal maintenance, development and reactivity of the nervous system. From the viewpoint of function, the tie-up between psychical characteristics and nerves is due to the fact that most psychical activity is either stimulated by, accompanied by, conditioned by, or in some way •• Pende, op. cit., p. 2!!8. 460 LEO M. BOND depends upon some form of nervous activity. The tie-up between the nerve activity and the endocrine glands is due to the fact that the nervous system and the endocrine system are so intimately correlated as to be inseparable at any functional moment. The second fundamental criterion which we must adopt in our constitutional analysis is that of the functional examination of each separate apparatus, but most of all, that of the one great apparatus-the neuro-endocrine--which by unanimous consent of all our best modern constitutionalists serves to establish a vital neurochemical coordination, a neuro-chemical consensus between all the parts and all that is most characteristic and personal in the constitution. 61 Both when devising the fundamental problems of endocrinology in the experimental field, and when studying pathological anatomy and many endocrinopathies, it was soon observed, and time has confirmed this notion more and more, that the humoral (i. e. endocrine secretional) correlation cannot be considered as a mechanism independent of the nervous correlation, but must be considered as parallel to it and more than parallel; they are intimately interwoven for their separation is imposrible at any functional moment. 62 ... the secretions of these glands (the endocrines) influence profoundly the activities which are under control of the autonomic nerves and incidentally also those influenced by the voluntary nervous system with all its implications. A change in the hormonoautonomic mechanism must have its reciprocal effect upon those organs or tissues which are controlled by the affected gland and its related nerve mechanism. 63 It has been said that the sympathetic nervous system is the keyboard upon which the endocrines play. 64 The most ultra-microscopic activities of the molecules and atoms in the highest nerve cells and nerve tissues are dominated. The speed of their chemistry and their associations and thus the speed of thought are regulated (by the internal secretions) .65 Later we will consider some of the particular psychical characteristics attributed to particular hormones.

The terms "mind" and "mental " are often used by them in a broad sense to include all or most of the psychical functions, intellectual, emotional, imaginative, etc. It is impossible to review here in detail all the facts accumulated concerning the influence of the internal secretions upon all the processes of mind, intellectual and emotional. A volume would not suffice for their adequate consideration. Reflexes, instincts, habits, tendencies and emotions are involved in their machinery. The development and normal functioning of the intellectual and emotional functions are controlled by them. Acuteness of perception, memory, logical thought, imagination, conception, emotional expression or inhibition and the entire content of consciousness are influenced by the internal secretions. 66 The most modern study of the relations between the hormones and the degree of mental development, proves in the most convincing manner the first class regulative influence, that the harmonic pattern exercises upon the formation of what we call character, that is, upon the determinants of the different forms of feeling, thinking, and acting that characterize different men. 67 In view of the function that the hormones, in collaboration with the nervous apparatus of the vegetative life, exercise in establishing the correlations between all the parts of the organism and between the somatic and psychic aspect of the individual personality, and hence, in view of the preponderant part which these play in the determination of the somatic-psychic constitution, we can understand how congenital and hereditary inadequacies and anamolies of the endocrine system come to occupy a very high place in modern constitutional pathology. 68 The influence of the endocrine glands upon the rate of all bodily and mental processes concerns every medical specialist, but more particularly the neurologist and psychiatrist. Even before a child is born, its nervous and mental make-up is determined in great part by the endocrine factors inherited from its parents, which endow it with normal or abnormal mental power, facility in nervous reaction, etc. Throughout life, the mind and nervous system remain reflectors of the state of the endocrine glands .... S. Distefano, Endocrinologia (Turin, 1929), p. 345. Pende, op. cit., p. 222. • 6 Ibid. 67 68 462 LEO M. BOND . . . the degree of emotional stability and the mental and emotional reaction to the stimuli which bombard each individual .through every hour of the day are all, to a considerable extent, under endocrine control.69 Without going into detail, as yet, as to the anatomy of particular glands and the various functions of their respective secretions, we will give here a few typical instances to illustrate the way in which the endocrinologists explain how the endocrine secretions affect psychical activities and determine psychical characteristics. First in the emotional sphere; and,' in particular, with regard to fear and anger. When an individual comes in contact some strong fear-arousing stimulus, the medulla section of his adrenal glands immediately increases the output of its hormone," adrenalin" (sometimes called adrenin). This increased supply is picked up by the blood stream or the lymph and quickly carried to various nerve centers, nerve endings, etc., throughout the body. The perception by the "associative memory " of the sensations arising in the various organs and tissues as they react to this increased supply of adrenalin, constitutes according to Berman, the emotion of fear. Some of the internal functions affected by the increase of adrenalin are the blood pressure, heart beat, respiration, etc. The outward manifestations of these organic changes may be paleness, trembling, twitching of the limbs, quick or gasping breath, twitching of the lips, etc. Experimentally these same effects can be produced by intravenous injections of a sufficient amount of adrenalin, which, by the way, should also produce the emotion of fear, if Berman's assumption is correct that fear consists wholly in the perception of bodily changes. Apparently, however, the injected adrenalin produces only the symptoms of fear, not the emotion itself. This may be due, in the hypothesis, to a different attitude of the " associative memory " during such experiments. The various degrees of change in the organs and tissues affected, and hence, in Berman's hypothesis, in the amount of fear felt, as well as in its outward manifestations, would depend •• Wolfe, op. cit., p. 78i. EFFECT OF BODILY TEMPERAMENT 468 upon several factors: first, the amount of adrenalin released. This would depend upon the degree of susceptibility or reactivity of the adrenal glands to a stimulus of given intensity, which would be relayed to it, through the nervous system, from the organs involved in the perception of the fear-arousing object. This degree of susceptibility would depend upon the structure and functional disposition of the medulla of the adrenal gland itself, which would in turn depend upon its congenital condition, which would again depend to a great extent upon heredity, the supply of hormones furnished by the parent body, etc. Hence the degree of susceptibility or proneness to fear and the amount of fear felt in a given instance would, other things being equal, vary in different individuals according to the variations in the temperamental disposition of their adrenal glands. Another factor would be the susceptibility or reactivity of the other organs and nerves affected to the increased adrenalin supplied to them. This would depend on their structure and functional disposition, which would in tum have been conditioned congenitally by various hormones. Already we have an example of the complexity of interaction and interrelation in the endocrine system. But this is not all. An individual's characteristic way of acting when frightened interconnet!would also depend upon the adrenal glands. tion between the whole endocrine system is so close that a change in the rate of secretion .by one gland affects all the other endocrines by either inhibiting or accelerating their functioning, which results in a disturbance of the equilibrium of the whole organism. Adrenalin, e. g., disturbs the inter-muscular equilibrium in such a way as to tense the flexor muscles (the muscles of flight), and relax the extensor muscles (the muscles of attack) .70 Hence an individual secreting a large amount of adrenalin would be more inclined to flee than to attack when frightened; one secreting only a small amount might be more or less paralyzed when frightened and hence would be inclined neither to flight nor fight. However, if the cortex section of •• Berman, op. cit., p. 210. 464 LEO M. BOND the adrenals pours into the blood enough of its hormone, " cortin," to overcome the effects of the lack of medulla secretion, the inter-muscular equilibrium is disturbed in the opposite direction, i.e., for fight rather than flight, and anger results. " Or if," says Berman, " the cortical section pours in an overwhelming amount of its secretion from the first into the blood, there will be no fear but anger immediately. Habitually charging and fearless animals, like the bison, bull, tiger, or lion, possibly have relatively larger adrenal glands. Habitually fleeing and fearful animals, like the rabbit, have a small cortex and a wide medulla in their adrenals. 71 Courage, as a human trait, says Berman, is closely related to fear and anger, but involves besides an act of volition. But even to this he would give an endocrine basis. " Admitting that without the adrenals such courage would be impossible, the chief credit for courage must be ascribed to the prepituitary. It is the proper conjunction of its secretion and that of the adrenals that probably makes for true courage. A prerequisite for adequate prepituitary function is a normal secretion of the interstitial cells of the reproductive glands. Cowardice is said to be a characteristic of eunuchs." 72 An individual's mental reaction in emergency would also be influenced by the state of his adrenal glands, but particularly by the secretional disposition of his thyroid, the gland which empirical observation has established as being closely related to the speed of thought. Iodine, the chief constituent of " thyroxin," the thyroid hormone, . . . has been shown to increase the electric conductivity of the brain, that is, the rate at which electrons will fly through it. The thyroid may then be regarded as manipulating the amount of iodine brought to play upon the brain cells at a particular moment of danger or exaltation. Adrenalin increases the electric conductivity of the brain. Nerve impulses, and with them sensations and ideas, travel faster or flow more quickly through iodinized or adrenalized brain cells. In dangerous situations we think more rapidly and keenly, for in emergencies the blood floods the brain with extra thyroid and adrenal secretions. 73 n Ibid., p. 210. 71 Ibid., p. !Ul. u Ibid., p. !!00. EFFECT OF BODILY TEMPERAMENT 465 Here again the degree of brain activity in emergency would be influenced by the temperament of the adrenal and thyroid glands, by the degree of reactivity of the brain cells to these secretions, etc. Individuals with characteristically poor adrenal or thyroxin secretion might tend to "go blank " in an emergency. In the intellectual sphere in general, some mental characteristics are attributed to thyroid secretion, others to the secretion of the frontal lobe of the pituitary, i.e., the prepituitary, which is quite similar to the thyroid in regard to the effects of its hormones, one of which has an accelerating effect on the thyroid itself. Speed of perception, memory, judgment, and reasoning depends to a great extent upon thyroid secretion, says Berman; accuracy of thought and" cool'dinating ability" depend on the prepituitary secretion. There is an element of judgment, in reasoning, as in perception and memory. And as in the latter, the thyroid determines the velocity. Quick thinking, as we call it, means good thyroid action, and slow thinking deficient thyroid action. The other element in judgment, accuracy, is influenced by the prepituitary. During adolescence there is a physical growth which consumes most of the secretion of the prepituitary. After adolescence, after the early twenties, when physical growth has ceased, the pituitary secretion seems to sensitize the cells of the brain to mental growth. The reaction potential of the pituitary, that is, its inherent, latent ability to supply a maximum of its endocrine for the nerve cells of the frontal lobes, is a chemical determinant of mental genius. It makes for the greatest coordination of experience, knowledge, information, tastes, and problems into one harmonious whole. And curiously, not only does it cause a fusion of intellectual material, it creates a desire for and a love of such material. We should expect to find extraordinarily well-developed prepituitary action among eminent philosophers and men of science, and we do. Adequate action of it is present throughout the range of normals who evidence sufficiently ripened judgment as they progress through life. The ability to profit by experience, and to make more and more accurate judgments as one grows older implies at least a maximum efficiency of it. This maturation is not at all universal. Even after middle age, after forty and fifty years of reasoning, some individuals retain the juvenile mind of their youth. Like the Bourbons, they have learned nothing and forgotten nothing. Their prepituitary insufficiency, often coupled with a postpitui- 466 LEO M. BOND tary excess, and other instabilities and disequilibriums in the endocrine system, render them immature morons, compared with what might be expected of them for their years. They are people who are old enough to know better. For the same reasons inhibition and emotional control are poor in them. 74 To just what extent each individual step in such explanations has been verified by empirical observation and experiment, is difficult to say. Not all the endocrinologists would be as willing as Berman is to assert definitely that particular kinds of intellectual acts can be attributed to particular hormones. However it is quite generally admitted even outside the school of the endocrinologists that mental ability in general corresponds to the characteristic supply of tyroid secretion. Also the general activity of adrenalin in fear and anger has been quite well established by physicians and scientists other than those coming under our classification of "endocrinologists "; for instance Walter B. Cannon, who summarizes his experiments, observations and conclusions in his book, " Bodily Changes in Pain, Hunger, Fear and Rage." 75 But whatever validity such conclusions might have in the physiological and phenomenal order, to give, for instance, the speed of electrons flying through the brain cells as an adequate and complete explanation of mental ability is certainly gratuitous and must inevitably lead to materialistic interpretations of psychical phenomena, unless something more is known about the nature of the intellect and its functional relations to the organic brain. From the above accounts of the part played by the secretions in emotional and intellectual processes, one might suspect the relation considered to exist between the endocrine secretions and "character," which for the endocrinologists, includes, as we have noted, the modifications brought about in the innate psychical characteristics by extraneous influences. The number and kinds of stimuli with which an individual would most frequently come in contact would depend to a great extent upon •• Ibid., pp. !ll5-!U6. •• Walter B. Cannon, M.D., Bodily Changes in Pain, Hunger, Fear, and Rage (New York, 1929). EFFECT OF BODILY TEMPERAMENT 467 his environment, education, etc. From being frequently called upon to respond to particular kinds of stimuli, the endocrine glands themselves would become more or less habituated to reacting along certain lines; some glands would be called upon more frequently than others and to a greater extent in one individual than in another, etc., always, however, in proportion to their native temperamental dispositions. This would have its repercussions in the entire endocrine system whose characteristic equilibrium would be modified along certain definite lines. The physiological modifications might result, to some degree, in corresponding modifications of innate psychical characteristics, but again only down to the level of and in proportion to the innate, characteristic temperament. The possibility of countless combinations, interactions, and interrelations in the entire physio-psychical apparatus takes on a dizzying complexity. However, the most influential factor in the entire mechanism would ,be the over- or undersecretion characteristic of the gland most dominant in an individual's physiological make-up. Says Berman: A man's nature is chemically his endocrine nature. Primarily, when he is born, he represents a particular inherited combination of "different glands of internal secretion. They, constituting the inventory of his vital stock in trade, start his life. Afterwards food, the routine of his existence, education, disease, and misfortune, in short, environment, modify him because they modify his ductless glands and ·his vegetative apparatus as well as his brain, depressing some parts and stimulating others, and so rearranging the system. In particular will he be transformed as the gland is affected which is the center of the system to which the others adapt and accommodate themselves. The inertia of the system is very great, almost absolute, and always tends to return. 76 Choices, the psychology of selection of food, color, friends, mates, amusements also become explicable rationally. For conflicts among the different components of the vegetative system are continuous and inevitable. If the pressure within a viscus has been heightened and persists, that is, is not disturbed by some other associated factor or instinct, conduct results to lower the pressure to what it was before the instigator of the tension appeared. But if another •• Berman, op. cit., p. 468 LEO M. BOND instinct is sparked, or another associated factor comes into play, another focus of increased pressure within the vegetative system is created, with another stream of energy flowing to the brain and demanding an outlet. This clash of instincts, the struggle between different foci of the vegetative system competing for the possession of the brain, is a common everyday process in conduct. Which will win means which will will. And so we have an energetic basis for volition. Which will win appears to depend primarily upon the kind of endocrines that predominate in the make-up of the individual, secondarily with his education. For it is the endocrines that are really in conflict when there is a struggle between two instincts. And if one endocrine system conquers, it must be either because it is inherently stronger, its secretion potential, that is, the amount of secretion it can put forth as a maximum is greater (so explaining the term dominant), or because a past experience has conditioned it to respond, although the opposing endocrine system does not. The response of the ductless glands to situations varies with their congenital capacity, and acquired susceptibility. Capacity is a question of internal chemistry, modifiable by injury, disease, accident, shock, exhaustion. Susceptibility depends upon the play of the forces focusing upon them what may be summed up as associations. In the ability of one endocrine system to inhibit another we have the germ of the unconscious. Hence the modus operandi of the repressions and suppressions, compensations, and dissociations, which may unite to integrate or refuse to integrate, and so disintegrate and deteriorate a personality. As the personality develops, the vegetative system becomes susceptible to manifold associates of family, school, church and society, art, science and religion, and last but not least, sex. All the different nuances of personality are expressions of a particular relationship, transitory or permanent, between the endocrines and the viscera and muscles. Conversely, behavior shows what a person actually is chemically; that is what endocrine and vegetative factors predominate in his make-up. 77 Notice here, among other things, how the will, though admitted to be the deciding factor in the matter of choices and character, is summarily explained away by being surreptitiously reduced to a mere phase of the functioning of an individual's dominant endocrine. 77 Ibid., pp. 208-9. EFFECT OF BODILY TEMPERAMENT 469 These, then, are some of the high-lights of the endocrinal theory as to the causes of temperament, i. e. of the individual physiological disposition from the viewpoint of its effect on the psychical characteristics. The main basic features of the whole theory have been thus summarized by Berman: I. The life of every individual, in every stage, is dominated largely by his glands of internal secretion. This is, they, as a complex internal messenger and director system, control organ and function, conduct and character. The orderliness of human life, in the sequential march of its episodes, crises, successes and failures, depends, to a large extent, upon their interactions with each other and with the environment. 2. One or several of the glands possesses a controlling or superior influence above that of the others in the physiology of the individual and so becomes the central gland of his life, its dominant, indeed, so far as it casts a deciding vote or veto, in its everyday existence and incidents as well as in its high points, the climaxes and emergencies. 3. These glandular preponderances. are determining factors in the personality, creating genius and dullard, weakling and giant, Cavalier and Puritan. All human traits may be analyzed in terms of them because they are expressions of them. 4. Specific types of personality may be directly associated with pa:t;"ticular glandular prominences, so that we have the thyroidcentered types, the pituitary-centered types, the adrenal-centered types, etc. These are the prototypes in their purity most easily described and recognized. 5. Combinations of these, as well as of other glands-with joint predominance-occur and indeed form the majority of the populations. The phenomena of varieties may be thus in part explained. 6. Internal secretion traits are inherited. The variations in their heredity are essentially the structural representation of the resultant of a parallelogram of forces exerted by each of the parental prepotent glands. If they are of the same type, they may reinforce each other: if not, inhibitions and compensations will come into play. Mendelian laws may apply. 7. (Behold!) The process of evolution, as the play of natural selection upon these variations, becomes comprehensible from a new standpoint. 8. Certain diseases, and disease tendencies, both acute and constitutional, as well as traits of temperament and character, and predetermined reactions to certain recurring situations in life, are rooted in the glandular soils that compose the stuff of the individual. 470 LEO M. BOND 9. The unconscious, of which the vegetative apparatus is the physical basis, leads back to the internal secretions for the profoundest springs of its secrets. . . . 10. Given the internal secretory composition, so to speak, of an individual-his endocrine formula-and so his intravisceral pressures, one may predict, within limits, his physical and psychic make-up, the general lines of his life, diseases, tastes, idiosyncrasies and habits. 11. Within limits if the previous history of an cindividual is known, his physical appearance may be approximately described, and his future outlined. (This pertains to the morphological phase of the theory, which we have not discussed.) 12. Conversely, given the physical and psychic composition of an individual, and his past history, one may deduce the internal secretion type to which he belongs.78 This theory has been accepted by a large number of modern psychologists, at least as to its broad fundamental postulates, if not as to all the particular conclusions to which some of the endocrinologists would carry it. Most of the objections leveled against it are based on the assertion that not enough is yet known about the endocrine glands to warrant such sweeping conclusions and that the claims of the endocrinologists as to many of its more detailed features have not been sufficiently verified by scientific observation and experiment. To this the endocrinologists say that while much has yet to be learned about the endocrine glands, what has been definitely established is sufficient to serve as a basis for their conclusions. As to how far and to what degree of detail these conclusions can be carried, the endocrinologists are not all in accord. Kretschmer is probably the most restrained; Berman, the most enthusiastic, though it must be remembered that Kretschmer was only a pioneer in the field. In their writings, some of them have a way of so amalgamating what has been definitely established with what is only supposition, that it is practically impossible to detect which is which. In their objections to the theory, some of the modern psychologists have seen and pointed out the discrepancy between the material, biological premises and the immaterial, 78 Ibid., pp. 145-47. EFFECT OF BODILY TEMPERAMENT 471 psychological conclusions in the explanations of the endocrinologists. Among modern psychologists of the Thomistic school, the theory has been looked upon with favor, at least in its basic outlines, but only as to its validity on the physiological and phenomenal levels. Fr. Barbado, 0. P., the eminent experimental psychologist and publisher of many works on the subject, made, in 1926, something of a prophecy in regard to the theory. In the first place, the discoveries of the anatomical and physiological sciences demonstrate more clearly every day the influence of the nerve organs on all the psychical functions, and the work accomplished in recent years on the subject of the internal secretions leads one to hope that scientists will soon discover the decisive influence that such secretions exercise on the morphology of the organism as well as on the psychical characteristics, and, therefore, it is not being rash to think that endocrinology will furnish the key to decipher the mystery and the clue to explain the correlations of the organic world with the spiritual. 79 Writing in the "Revue Tomiste," five years later, he bears witness to at least the partial fulfilment of this prophecy even at that early date (1981). It is clearly demonstrated that a large part of the individual differences, both morphological and psychical, observed in the human species, depend on the functioning of the endocrine glands; and since these glands pour their secretions into the blood and the lymph, we may conclude that the composition of organic humors exercises a definite influence on the determination of individuating notes whether psychical or physiological. Thus it is that the condition of one's humors is an indication of the individual human personality, both in its exterior aspect and from the psychical point of view, particularly in the affective sector .... As to the action of the glands of internal secretion on the physical processes, it may be given as verified, that if not all, at least the thyroid, the pituitary and the adrenals are, without any doubt, stimulants of the superior functions, mainly of those pertaining to the affective zone, in such a way that today, with reason, a great •• P. M. Barbado, 0. P., "Correlaciones Del Entendimiento con el Organismo," La Citmeia Tomista, XXXIII (1926). 180ft. 472 LEO M. BOND importance is given to the character variables as a diagnostic of the humoral temperament. The influence of the thyroid upon the cognitive processes is decisively demonstrated. 80 For our present purposes, the main things to be noted about the theory are these: that physiological and psychical individuality is determined, on the material side, by secretions manufactured in certain glands, from the digested food, and poured immediately into the blood stream or lymph, by which they are distributed to all the parts of the body and from which each organ withdraws what is necessary for its nutrition and functional efficiency; that a balance is thus maintained in the structure and functional dispositions of each organ and of the body organism as a whole, an equilibrium which has its counterpart in the psychical characteristics, and that predominance of one or more of these secretions in the blood stream determines an individual's physiological and psychical type and is thus responsible for his individual characteristics. These are fundamental postulates of the theory. 2. The Teaching of the Ancients and Medievalists. We have seen, in a summary way, how, according to the ancient and medieval theory, the humors the structure and functional dispositions of organs and tissues characteristic of an individual and how through the medium of this physiological individuality they exerted a determining influence upon the individual psychical characteristics. Here we will glance at some of the details involved in this process, with a view to showing the striking similarity they bear, at least in fundamental points, to the modus operandi attributed by the endocrinologists to the endocrine secretions in the determination of this twofold correlated physiological and psychical individuality. A treatment of this kind must not in any way be interpreted as an attempt to defend, at least in their details, the scientific doctrines of the ancients and medievalists. That would be absurd. Theirs was definitely a pre-scientific age, in 80 Barbado, 0. P., "La Physionomie," Revue Thomiste, XXXVI (1931), p. 335. EFFECT OF BODILY TEMPERAMENT 478 the sense in which "science" is taken today, and subsequent discovery has proved the falseness of many of their more specific doctrines as to the causes of physiological structure. They had practically no knowledge of chemistry as we know it today and only a very crude notion of biology. Nevertheless from observation of the effects of what we know today to be chemical composition and activity in the human body, they arrived, with remarkable insight, at some fundamental notions of physiological functions which modern science, with all its paraphenalia, has been able to do little more than build upon, amplify, correct as to detail and place on a more solid scientific footing. If some of these older scholars had had at their disposal the accumulated knowledge of centuries and the means of precise analysis that the moderns have fallen heir to, we venture to say that they would have solved many of the problems over which modern scientists are still splitting their heads. With regard to the matters that we are presently discussing, the particular ancients and medievalists from whom we will quote in the following pages-for the most part, Aristotle, St. Albert the Great and St. Thomas-were not, we must emphasize again, ex professo doctors of medicine, but depended for much of their knowledge of biology, anatomy, etc., upon the theories offered to them by medical experts of their era, theories which the medical profession itself considered sufficiently verified to serve as a. basis for medical therapy. But meagre aud inaccurate in details as was this proferred knowledge, it was yet sufficiently sound in general principles to enable men like Aristotle, St. Albert, and St. Thomas to build upon it a sound psychological doctrine as to the body-soul relationship. The ultimate purpose, then, in pointing out the following similarities between the humors and the hormones as causes of physiological and psychical individuality is, as we have stated, to stress the fact that men like Aristotle, St. Albert, and St. Thomas had a sufficient knowledge of physiological principles upon which to construct a solid and impregnable psychology, the full significance of which the moderns have been unable even to grasp much less improve upon and which they would 6 474 LEO M, BOND yet disdain on the grounds that it was not built upon a knowledge of reality. To begin, therefore, with the hormones and humors themselves, the hormones are chemical compounds " of various types and of varying degrees of complexity. Some are simple organic compounds and can be manufactured synthetically, others are quite complex protein-like bodies." 81 As to their exact chemical composition, not too much is known. Only a comparatively few of the hormones have yet been sufficiently isolated to make chemical analysis possible. Of these only a few have been reduced to more or less accurate chemical formulae. The exact composition of even those hormones whose chemistry is sufficiently known to permit synthetic manufacture, is still open to question, as the endocrinologists admit, since the effects of these synthetic products have not always been found to be exactly parallel to those of the natural secretion. Thyroxin, the thyroid hormone, is one of those whose composition is best known, but the formula of even this hormone is given by Dr. Loewenberg as only approximately CnH1o04NI4.82 These chemically composed hormones act on the various organs and tissues with which they come in contact, to set up chemical reactions and effect chemical changes. One of the most easily observable effects of their chemical activity is the production of such sensible qualities as heat, or a lack of it, in the affected organs. With regard to the thyroid and adrenals, for instance, Berman says: If one wished to synthesize the two sets of observations, one would say that the thyroid augmented the acid and heat in the cells, the adrenal cortex diminished them and differences between individuals in these respects, with far-reaching consequences for all their well-being, would be the outcome of the thyroid-adrenal cortex ratio in them. 83 The ancients and medievalists, observing such effects of their " humors " as increased or decreased heat production in the 81 Matthew Steel, Biological and Clinical Chemistry (Philadelphia, 13-14. •• Bennan, op. cit., p. 76. •• Loewen berg, op. cit., p. 239. 1937), pp. EFFECT OF BODILY TEMPERAMENT 475 organs, and not being able to submit humors to chemical analysis, naturally concluded that they must be mixed bodies, composed, like other mixed bodies, of those things which were known to produce primarily heat and coolness, viz., fire and earth, and that the different degrees of temperature observed in the various organs and tissues were due to particular combinations in them of their component humors, the combinations differing in different organs of the same body and in the organs of different individual bodies. The same conclusions were drawn from the degree of dryness and wetness observed in various organs, namely, that these qualities were caused by the proportional mixture of their component humors, with their characteristic proportional content of the chief dryness or wetness producing elements, air and water. They had no way of knowing that the various proportions of heat, cold, dryness, and moisture observed in the body were due, not to various combinations of fire, earth, air and water, but to various combinations of some of the very same chemicals that are known today to enter into the composition of fire, earth, air, and water, and to be responsible for their characteristic heat, coolness, dryness, and moistness, viz., hydrogen, oxygen, carbon, nitrogen, etc. Had they been able to carry their observations one step further back by means of chemical analysis of the blood, they would have discovered this fact. The hormones, therefore, are composed bodies whose qualities result from various combinations of chemical elements; the humors were also composed bodies whose qualities resulted from various combinations of what were then thought to be elements, but which are known today to be not chemical elements, but various combinations of chemical elements. Modern chemists can hardly afford to scoff at this ignorance of the older scholars, when they themselves are now beginning to suspect that what they have long considered as chemical elements are in reality only combinations of simpler substances. The hormones are produced from the digested food, in the endocrine glands, whose distinctive and characteristic feature is that they distribute their products throughout the body by 476 LEO M. BOND emptying them directly into the blood stream instead of dispatching them through particular ducts. As mentioned before, Hippocrates, the Greek physician of the fourth and third centuries, B. C., considered the blood as being produced in the heart, the phlegma in the head, the atra-bile in the spleen and the bile in the liver. Galen, the Graeco-Roman physician of the first and second centuries, A. D., taught that all four humors were produced in the liver, and his doctrine became the standard one throughout the early and middle centuries of the Christian Era, in fact until comparatively recent times. St. Albert the Great (1198-1280) thus describes the manner in which the four humors were thought to be produced and distributed throughout the body, according to the Galenic theory: The digestion of food takes place in the stomach after the liquids we drink have mixed with the foodstuff. This mixture is necessary the whole mass a juice might be formed which will so that slide and flow through the veins of the liver. After digestion the stomach absorbs some of the juice, and some it dispatches through the veins to the liver, and the rest it sends through the portal vein to the intestines from which the liver draws the juice through the mesenteric veins. The vesenteric veins are narrow strong veins running throughout the intestines: and through these veins the juice passes smoothly until it disperses into the capillary veins which are in every part of the liver: nor would it ever be able to pass through such small vessels, unless it were made fluent by the liquids we drink. But the capillary veins which are interspersed through the whole body of the liver, join in the thick part of the liver, and there they form a large vein and in this a boiling down process (of the juice) takes place, and that happens which happens when any mixed juice is greatly heated. Some of it rises to the top as a foam, and this is the material of the natural cholera; and some of it sinks to the bottom as heavy earth-like substance, and this is the material of the melancholia; and some of it becomes thin and pure, and this is the matter of, the blood and some of it remains as a semi-watery liquid, and this is the matter of the phlegma. All these humors then are produced in the bulky portion of the liver under the influence of the heat coming from the heart ... and then the large vein which connects the heart with the thick section of the liver, divides in this section into two main branches, one of which extends to the upper parts of the body and the other downward and through these veins the blood (carrying the other three EFFECT OF BODILY TEMPERAMENT 477 humors with it) is carried to the members, oozing out at all the vein terminals: and when it thus oozes out it is absorbed by the members and nourishes them. It is evident then that a humor is a humid fluent body prepared by a boiling down process for the nourishment of the members. For a humor supplies the nutriment to the bloody or phlegmatic or choleric or melancholic contents of the members, i. e., since the members themselves are composed of humors, their humoral components receive their nourishment from corresponding humors. 84 The thing which strikes one most in this passage is the fact that the liver in which the humors were produced was thought of as a gland of internal secretion, an endocrine gland in every sense of the word, since it manufactured its secretions from the digested food and dispatched them directly via the blood stream to all the organs, which needed them for their maintenance and operation. The liver, then, bore a close resemblance in its characteristic functions to what are now called the endocrine glands, and its products, the humors, were closely allied in their general activity and purpose to what we now call hormones. Certainly, as we know today, no one gland produces all the hormones, nor are there only four kinds of hormones, nor is the activity of the hormones as simple as that ascribed to the humors; nevertheless the basic features, the general principles are there, and the humoral system can be rightly considered as a sort of simplified prototype of the endocrine system. Curiously enough, the whole modern notion of glands of internal secretions as distinct from those of external secretion, had its origin in observations of the activity of the liver. In 1855, a French physician, Claude Bernard, after much observation and experimentation, concluded that the liver added sugar to the blood on its way to the heart. " Extraction of the liver then revealed the presence in it of a form of starch, an animal starch, which Bernard called glycogen, the sugar maker. The origin of the sugar added to the blood on its way from the liver to the heart was thus settled. Bernard went on to hail glycogen and the sugar derivable as the internal secretions of •• Albert the Great, De Animalibus, XII, t. 1, cap. 6. 478 LEO M. BOND the liver, and to erect, and then drive home, a theory of internal secretions and their importance in the body economy." 85 It has since developed, however, that the liberation of sugar from the glycogen in the liver is not a function of the liver itself but is due to the action of adrenalin, a hormone of the adrenal glands situated above the kidneys. However, the fact remains that as late as 1855 scientists were still making mistakes as to the precise activity of the liver, though they were partially correct in their observations. Bernard was right at least as to the place where the blood sugar is elaborated and as to the substance from which it is elaborated if not as to the manner of its elaboration, and it was this observation that opened up a whole new line of thought in modern medicine. This is a significant thought when one is inclined to ridicule the value of the empirical observations of the older scientists. Even more significant is the fact that endocrinologists are returning today to the idea of the liver as having important endocrine activity along with its other activities. In fact Berman claims that " it has been demonstrated" to produce at least two hormones, to which, however, no names have yet been given. It is a curious fact that the liver, which inspired Claude Bernard to invent the words, " internal secretion," for a long time failed to be even listed as one of the major endocrine glands. Certain discoveries of the last few years have, however, restored it to its pristine position, and it has been demonstrated to be the source of at least two hormones which are of the greatest importance in maintaining the normal equilibrium of the body. It may contain many others. 86 We have noted that the general function of the hormones is primarily to regulate the functioning of all the cells, tissues, and organs of the body by stimulating or retarding their activity as necessity demands and thus to maintain a proper balance and coordination among the functions of all the various parts of the organism. One of the most important phases of their function and one through which they exert perhaps their •• Berman, op. cit., p. 116. •• Ibid. EFFECT OF BODILY TEMPERAMENT 479 greatest influence in the determination of physiological individuality is their regulation of metabolism by determining the speed and efficiency with which the· various cells, tissues, and organs assimilate the nourishment delivered to them in the blood stream for their sustenance and functional efficiency. In the embryo, before the individual's own endocrines are completely formed, this is accomplished in regard to the cell growth, multiplication, and differentiation, largely by the hormones received from the parent body, and in the fetal stages by the functioning of some of the individual's own endocrine glands. From the fetal stage on, development depends to a great extent upon the type of blood, as to hormonal content, with which the various cells, tissues, and organs come in contact. The humors were considered to produce practically the same effects on organ formation and metabolism, though in a simpler and more direct way by entering directly into the composition of the tissues and organs and later by supplying them directly with their nutriment. In the prenatal period, organ formation and differentiation was accomplished by three successive stages of composition, that namely, of the humors, the " similar members " and the organs. The " similar members " were for the older scientists the various kinds of tissue, nerve, bone, etc., from the combinations of which the different " official members" or organs were formed, though they sometimes used the general term "members" to designate both similar and official members. This process of composition is summarized by Albert the Great in the following quotation. The things here said of animal bodies in general, he considers as applying to the human body also " inasmuch as man is the most dignified of animals and has more perfect members as to number and figure, than any of the others." 87 First therefore, we may say, that in animal bodies there are three compositions. And the first of these is called " commixture " which results from the mutual alteration of the four elements and their qualities by their reduction to a mixture by means of their 87 Albert the Great, op. cit., I, t. I, cap. I. 480 LEO M. BOND primary active and passive qualities, their forms having disappeared in the process; which mixture has differences and grades according to the difference of the animal bodies. But this mixture of elements continues to undergo alteration until the four humors are formed from it, which are the blood, the phlegma, and both biles, the red (cholera) and the black (melancholia). The second composition pertains to temperament and is accomplished by the transmutation of the humors, producing from this humoral transmutation the similar members: and therefore this operation terminates with the formation of the similar members. The third composition is the formation of the official member (organ) from the similar members, and the constitution of the whole body from the similar and official members: which compositions, although they appear to be two compositions are really only one: since the similar members are not altered as to their forms in the composition of the official member: and the official members have the same mode of composition in the constitution of the whole body. The first of these compositions are prior in time and generation, the second is next and the third is the last. 88 Before the formation and functioning of the liver, the humors entering into the composition of the similar members were, presumably, those derived from the parent body, as in the case of the hormones. In the third stage of composition, that is. the composition of the organs from the similar members, some of the similar members determined the structure of the organs, others were concerned with its operation: . . . some of the members are as the material of the organic member: since each organic member is sustained by and composed of them, namely from bones, flesh and nerves and the like; in such a way that certain of the similar members are adapted to the substance of the organs, and others to its operation. 89 Hence the structure and functional dispositions of the organs, i. e. their temperament, would depend upon the temperament of the similar members. But the temperament of all the members, both similar and official, depended upon the type of nutriment they received, whether in utero or postnatally, "for •• Ibid., XII, t. 1, cap. 4. 88 Ibid., cap. 2. 481 EFFECT OF BODILY in general every member is assimilated in its natural temperament to its nutriment." 90 All nutriment was furnished by the blood, hence the type of nutriment received would depend upon the type of blood with which the members came in contact, which would in turn depend not only upon the blood itself but to a great extent upon the quantity and quality of the other humors contained in and carried by the blood stream. Any excess of one or more humors in the blood would affect all the members by disturbing their metabolic processes, which would affect, for better or for worse, their structural and functional dispositions or temperament. " The most potent factor in determining the good disposition of the members is the blood." 91 And if it (the blood) should incline toward the phlegma (i.e. by reason of an excessive phlegma content) it becomes watery: hut if to the red bile (cholera), it becomes somewhat turbid: and if to the black bile (melancholia) it becomes fetid and it undergoes many other variations (of these states) from the admixture of these humors. 92 ... humors are the nutriment for the similar members which compose the organs: for all the members receive their increase from humors. . .. But these humors have some superfluities which conduce to an improvement or deterioration of the temperament, as in the blood there are various differences when one blood is compared to another; since some blood is thinner, and some and some purer, some more turbid and some warmer (depending upon the proportional mixture of other humors in it) .93 The hormones, as we have noted, set up and maintain a balance in the functioning of the whole organism. They accomplish this, proximately, by regulating the functional speed and determining the functional efficiency of each organ in relation to the functioning of the whole body and, remotely, by their influence on the structure of the organs both in their formative stage and later as to their development and maintenance. Any excess or defect will upset the general organic balance. The resulting numerous variations in the grades of " normal " departure from perfect balance are the bases of 80 81 Ibid., cap. 4. Ibid., cap. m, t. 2. •• Ibid., XII, t. I, cap. 2. ea Ibid., 482 LEO M. BOND physiological individuality, and the general over-aU predominance of one or more kinds of hormones in the entire system determines the various " types " of individuality. The humors also regulated the functional balance necessary for the efficient operation of the organism as a whole. Balance in the whole organism depended upon the efficiency with which each organ performed its function. This efficiency depended upon the good structure and functional dispositions of the organs. Good disposition of the organs was a question of proper balance in each of the humoral qualities, heat, cold, moistness and dryness, which depended in turn upon the proper of humors in the organs themselves and in the blood stream from which they were fed. Proper balance in each organ was not a question of absolute equilibrium between all the four qualities, but of a proportional balance of qualities that was fitting for the individual organ according to the part it had to play in the functioning of the whole organism. A predominance of heat was required in some of the organs, of coolness in others, of dryness in others, etc. If the proper relative predominance of a quality was maintained in each organ, the organs would function properly and a more or less perfect equilibrium would result in the structure and functioning of the organism as a whole. Any upset in the proportional balance proper to an organ resulted in an upset of the equilibrium of the whole organism. We will give a few of the many passages from St. Albert dealing with these matters: . . . a man is not well balanced unless each member which is in him has that disposition which it ought to have according to the demands of his equilibrium, though considered in itself, it (the organ) may not be evenly balanced: for such inequality reduces the whole to equality. For the heart is very warm: but this is required for the reduction of the other (organs) to equality. 94 The seventh mode (of equilibrium) is in the members according to which mode each member according to its species has its own proper quality, whence we say that the bone should be drier than the other members, and the brain should be more humid, and likewise with the others. 95 "Ibid. •• Ibid. EFFECT OF BODILY TEMPERAMENT 483 . it (this equilibrium) has a latitude and a mean, when, namely, the member is in the best disposition in which it is able to be.96 The proportional balance proper to each organ according to its function in the organism as a whole depended upon the humors. This proportional balance in each organ was not, as we have said, an even balance, but a balance characteristic of the organ itself, which in most organs was actually an imbalance,i. e. in relation to an absolute equilibrium. In the realm of heat and cold, this imbalance was called " intemperance." And intemperance in general comes about in two ways, without matter, i.e. through the quality alone, or with matter, which is some humor. Without matter, as when something is greatly altered by something hot or cold, in such a way that only the quality is augmented in it, as things become warm near a fire, or cold near ice. But with matter, of a humor, something is called intemperate in two ways: for either that matter which causes the intemperance (i.e. the humor) penetrates into the member or it is contained in the veins and nerves. Among the intemperate organs the hottest in the body is the heart. 97 If the equality of the general temperament proper to each individual was upset within a certain range, the result would be a better or worse, although still " normal," general condition. If the upset was too great, the individual's general condition and his " life " would be abnormal or pathological. But beside the aforesaid modes there is an equality of temperament which is proper to the individual according to which he is able to live and if this equality is upset the temperament becomes unbalanced: and this also has a certain latitude and two terms: and the mean is the equality according to which the life proper to himself is best: and if the equality departs a little from this, his life is good, not best: and it can depart so much that it will be unbalanced and bad. 98 The variations of temperament within the range of " good " would determine normal types of physiological individuality. The " perfect man " would be one whose general temperament was in perfect equilibrium. But such equilibrium rarely, if •• Ibid., cap. 4. •• Ibid. •• Ibid., cap. 4. 484 LEO M. BOND ever, existed. According to the degree in which an individual approached or departed from this perfect norm, he would have a better or worse temperament. But the first mode of equality, which is according to the nature of the species in comparison with other species, has a latitude, insofar as all individuals of one species have the same (specific) equality. But there is a state which some individual might attain most absolutely and in the highest degree and other states consist in degrees of approach to that state. Therefore the most absolute mode of equality and the mode of this latitude pertains to the second mode of equality, as if we would say that some man possessed the greatest equality and the most absolute which is possible to the species and nature of man. This man says Aristotle in " First Philosophy " would be the norm of measuring all other men in that he would exhaust the possibilities of the human species, and others would participate in these possibilities according to their approach to him. Rarely, however, is perfect equilibrium of this kind found because such a man would have to have in all his members .the most perfect disposition and balance of which his nature is capable. 99 The predominance of one humor in the whole system was the basis of various types of individual temperament: . . . temperament is the quality resulting in animal bodies from the quality of contrary activities according to which the qualities themselves are altered by each other. 100 However it must be known that every man has his own individual temperament. 101 There is a diversity among men due to the fact that the (individual) nature of some follows the cholera more, and that of others, the other humors. 102 These, then, are a few of the points of similarity observable between the humors and the hormones as to their nature, production, function, and effects upon the human organism as well as to their influence in the determination of physiological individuality. They have, besides, many other points of similarity too numerous to discuss here. Now such similarities are •• Ibid. Albert the Great, op. cit., 101 Ibid., cap. !e. 100 t. 1, cap. 4. 101 Ibid., IT, t. 2, cap. s. EFFECT OF BODILY TEMPERAMENT 485 too close and too numerous to be merely accidental; they must arise from the fact that the chemical substances now known as " hormones " were known, at least as to their effects, to the ancients and medievalists and were given by them the general designation of " humors," a name, by the way, which is still applied to the endocrine secretions by some of the moderns. The fact that the older scientists arrived at their deductions as to the nature and functions of the " humors " by concluding from the effects observed that the causes must be something like this, in no way invalidates their conclusions, at least as to the general nature of those causes. Their limited knowledge of biology, anatomy, and chemistry made it impossible for them to conduct a more accurate and scientific investigation of the physiological entities whose effects they observed, nevertheless they were able to arrive at certain basic notions about them which are quite in line with what modern science now claims to have established. As a matter of fact, much of the data about the hormones presented by the endocrinologists today and purported to have been culled from "scientific" observations, represent mere conclusions drawn from the observation of various disease symptoms, etc. The comparatively few hormones that have been isolated and chemically analyzed are by no means sufficient to explain the elaborate mechanism offunction and effect attributed by the endocrinologists to the endocrine system " in toto," nor do their experiments with hormone injections, partial removal of glands, etc., by any means always prove what they are supposed to. The fact that the ancients and medievalists were never able to analyze chemically nor produce synthetically what they called " humors " does not prove that their deductions were something dreamed up out of the blue with no empirical facts as their basis. Their conclusions were based on empirical observation, albeit of a less specialized kind than is possible today. As to psychical characteristics, the ancients and medievalists arrived at the same general conclusion as have the endocrinologists, namely, psychical individuality was based upon physiological individuality. Here they had not much less to 486 LEO M. BOND go on than have the endocrinologists, for the data of psychical phenomena is more easily observable by common observation, experience, and introspection than are those of the intricate body chemistry. The principle thing that modern psychometrics has proved is the fact that they prove very little more than common observation can prove and, frequently, considerably less. The endocrinologists base most of their conclusions as to the relation of hormones to psychical characteristics upon the observance of changes in psychical qualities accompanying various sensible changes in organic dispositions known or thought to be caused by under- or oversecretion of the endocrine glands. This type of observation was open to and was in fact widely used by the ancients and medievalists. Like the endocrinologists, they too attributed these psychical changes ultimately to that which they considered as causing the said bodily changes and diseases, namely the humors. The fact that this ultimate basis has since been proved to be hormones instead of humors is of little importance in the field of psychology. The significant thing is that the older scholars recognize the fact that psychical qualities are determined to a large extent by organic dispositions. And, more important still, is the fact that they, unlike the endocrinologists, realized that the explanation of this fact does not lie wholly in the organs themselves, as we shall see later. We have noted how the endocrinologists consider the nervous system as one of the most important organic media through which the hormones affect psychical qualities. The ancients and medievalists had the same idea, at least with regard to the sensitive psychical qualities, even though their knowledge of the nervous system was very rudimentary. We say, therefore, that a nerve is a viscous substance, directed from the brain through the body, that through it sensation and motion might be given to the body. For the principle utility of the nerve, which is substantial to it is that through it as an organic medium, the whole body should receive the power of sensing and moving.103 108 Ibid., I, t. fl, cap. 18. EFFECT OF BODILY TEMPERAMENT 487 Since the nerves were one of the " similar members " entering into the composition of organs, their structure and functional dispositions were, like those of all tissues and organs, largely dependent upon the humors. The nerves in the skin, for instance, were maintained in a temperate disposition by reason of the blood with which they came in contact: " ... the cause of the temperance of the skin is that the nerve tissue which is interwoven in the skin, is tempered by the blood .... " 104 But a more proximate and important medium through which the humors influenced the psychical characteristics were those unique inventions of the ancients and medievalists, the " vital or animal spirits," which were sort of rarified forms of the humors and acted as carriers for the distribution of the various powers of the soul to the appropriate organs of the body;" very thin vapors," says St. Thomas, " through which the powers of the soul are dispersed throughout the parts of the body." 105 The " spirits " were generated at high temperature from the blood in the heart, whence they passed through the veins to the ventricles of the brain which served as a kind of store house where the spirits underwent a " cooling " process due to the coolness and humidity of the brain tissues, and whence they were dispatched throughout the body as bearers of the soul's powers. They accompanied the blood to all the parts of the body, and being products of the blood humors, their qualities varied according to the humoral content of an individual's blood. Slow-moving blood, heavy with the melancholia, produced slow-moving, cloudy spirits; clear, fast-moving blood, rich in cholera, produced speedy and clear spirits, all of which qualities were reflected in the individual's psychical characteristics due to the various effects of different kinds of spirits upon the organs through which the soul's powers were exercised. Just how the spirits functioned in some of the phychical activities we will see shortly. While the nerves were important as an organic medium of sensation, it was the spirits that acted as "go-betweens " between the brain and the nerve tissues in various parts of the body. Fantastic as all this sounds to modern ears, it is 10 ' Ibid., XII, t. 1, cap. 4. 100 I Sent., d. x, q. I, a. 4. 488 LEO M. BOND not at all unlikely that the postulation of "spirits " by the older scientists resulted from their observation of phenomena which are attributed today to that mysterious telegraph system whereby messages are relayed along the nerve tracts by means of a succession of nerve impulses. As we did with regard to the endocrinologists, we will give here a few quotations from the older writers expressive of their notions as to the effect of humors, through the medium of spirits and organs, upon the psychical characteristics in general. It must be remembered that the quality of the blood resulted from its characteristic humoral content as did also the qualities of the spirits generated from and accompanying the blood. "Fibers" or" fibrin" (fibrae) was a form of the earthy humor in the blood, i. e. the melancholia. The " watery " element was due to the phlegma. To begin with Aristotle: Some animals ... have a keener mind than others, not because of the coldness of their blood but rather because of its thinness and purity, neither of which elements are found in earthy blood: for those whose humors are lighter and purer have a more mobile sensibility ... those animals are more timid whose blood is very watery ... and so those whose heart is of this temperament are more prone to fear. Those whose blood is rich in thick fibrin, have a more earthy temperament, and habitually become angry, and are prone to rage. The nature of the blood is the cause of many modifications that are found in the characteristics and sensibility of animals. 106 Concerning Galen's notions, Roback says: In this way Galen was able to assign a definite cause for each of the four outstanding types of individuals in the preponderance of the so-called bodily humors. The sanguine person, always full of enthusiasm, was said to owe his temperament to the strength of his blood, the melancholic's sadness was supposed to be due to the over-functioning of the black bile, the choleric's irritability was attributed to the predominance of the yellow bile in the body, while the phlegmatic person's apparent slowness and apathy were traced to the influence of the phlegm. 107 Says Moses Maimonides (1135-IQOQ A. D.): 106 107 De Partibus Animalium, IT, cap. 4 (ed: Didot, pp. 285-86). Roback, op. cit., p. 11. EFFECT OF BODILY TEMPERAMENT 489 For instance, a man whose natural constitution inclines towards dryness, whose brain matter is clear and not overloaded with fluids, finds it much easier to learn, remember, and understand things than the phlegmatic man whose brain is encumbered with a great deal of humidity. 108 And St. Albert the Great: Since the structure and disposition of the members are generated and nurtured by the blood, it follows that inclinations to the passions may be kn6wn to some degree from the disposition of the organs. 109 Loxus was not so wrong when he said that the blood was the seat of the soul, if it is understood that the soul is there not in respect of its essence, but in respect to the inclinations of its affections; for the spirits, which are the vehicles of its powers, are generated from the humor of the blood; and it cannot happen that something that is carried does not follow in many respects the movements of the carrier. For we say that the melancholies are sad and grave, that they suffer from terroristic images and that they are held in this condition by the gravity, frigidity, and horror of the melancholic blood; for images received in a horrid mind become terroristic. We see that those having a sanguine temperament, because of the subtility, clarity and temperate condition of the blood, have precisely opposite affections. The cholerics are prone to anger and fervor, and in this condition apprehend fiery representations due to their light and fervid blood. And that is why we define passions in connection with the blood and say that anger is the affluence of blood against the heart. 110 Moreover intellect in man and the estimative power in other animals are more refined and better, and less refined and worse according to the of the blood and of the humor which takes the place of blood (i.e. in bloodless animals), not indeed because of coolness of the blood, but because of its greater or less thinness and clarity. Earth lacks subtility and clarity, wherefore those having an earthy blood (melancholies) are duller and slower in concepts and operations of the soul. For an animal having a more refined and purer natural humor, has a better sensibility.m And St. Thomas: 108 Moses Maimonides, Eight Chapters of Ethics (quoted by Roback, op. cit., p. 43). 109 100 Albert the Great, op. cit., I, t. 2, cap. I. 111 Ibid., Xll, t. 2, cap. I. Ibid. 7 490 LEO M. BOND But the subject of delectation and of all the passions of the soul is the animal spirit which is the proximate instrument of the soul in the operations which are exercised through the body. But for the spirit to be apt for delectation, two things are required, namely due quantity, and due quality. Due quantity refers to an abundance of spirits, for two reasons. First because a spirit abundant in quantity, abounds also in power. Secondly, because since for the passion of delectation there is required a dilation of the heart and the spirits, dilation cannot take place when the spirits are few, because nature constricts them and confines them to their source. But when the spirits are many, nature is able to retain some in their source and still pour them out in abundance for dilation. Due quality depends upon three things. First, that (the spirit) be of a moderate temperature. Second, that the spirit be clear and not cloudy; and therefore melancholies, in whom the spirits are earthy and obscure, are prone to sadness. Third, that its substance be midway between thickness and thinness. For if it is excessively thick or excessive thin, it is not adapted to delectation, because it is not easily dilatable. The greater therefore is the disposition to joy or sadness on the part of the material cause, the less is required on the part of the formal cause, and vice versa: and therefore some individuals become joyful or sad on slight provocation, but others only on great provocation.U 2 This last quotation from St. Thomas gives us some idea of the notions of the older scholars as to how the humors and spirits functioned in relation to joy and sadness and how proneness to these passions depended upon the humoral disposition of the blood. We will now glance at their theories as to humoral function in fear and anger, as compared to the endocrinologists' ideas of hormonal function in these same passions. We have noted how, according to the endocrinal theory, fear causes a release of adrenalin by the medulla section of the adrenal glands, which results in an increased blood pressure, heart beat, nerve excitation, etc. The perception by the associative memory of these various bodily changes constitutes according to Berman, the emotion of fear. It would seem from this that the greater the release of adrenalin, the greater would be the fear. But it seems that the reverse is true, for apparently the 11 " IV Sent., d. xlix, q. 3, a. 2. 491 EFFECT OF BODILY TEMPERAMENT sensations in the organs, perceived by the associative memory, are due not simply to stimulation but to the proportion which exists between the amount of stimulation demanded by the organs in a fear-arousing situation and that which is actually supplied. If the heart, nerves, muscles, etc., cannot respond adequately to a situation by reason of an insufficiency of material stimulants, the individual will be incapable of fight or flight and hence his fear will be greater. As Berman says: In the facing of crises, the adrenal functions as the gland of combat. And indeed, as I have mentioned, the more combative and pugnacious an animal, the more adrenal it has, while the timid and meek and weak have less. Of the two animals, if in one the heart should begin to beat more strongly, the blood pressure to rise, the blood to flow more rapidly through the attacking instruments .... while the other experiences none of these, the former will be the victor in fight or flight.113 Moreover, fear produces coolness in some parts of the body because the blood has a tendency to withdraw from the outer parts of the body and concentrate around the muscles and the organs which must be conditioned for fight or flight. The blood, that primary medium of life, the precious fluid that is everything, must all or nearly: all be sent to the firing line, the battle trenches, the brain and muscles, now or never. So the blood is drafted from the non-essential industries-from the skin where it serves normally to regulate the heat.U 4 This withdrawal cause coldness in the extremities, which becomes even more pronounced in persons whose adrenals are habitually insufficient. There results (from exhaustion of the reserve supply of adrenalin) a condition of temporary or chronic adrenal insufficiency, supposedly an insufficient function of the gland as a whole. In persons so afflicted there appears a fatibability, a sensitiveness to cold, cold hands and feet. 115 The inadequate response of the organs involved in fear would be due to an insufficient supply of adrenalin released into the 118 Berman, op. p. 79. 1" Ibid. 110 Ibid., p. 81. 492 LEO M. BOND blood stream. Hence a person whose supply of adrenalin was characteristically inadequate, due principally to innate defective disposition of his adrenal glands, would be more prone to fear; i. e. he would experience fright on slight provocation due to the failure of his adrenals to supply the organs with sufficient hormones to enable them to react adequately to the feararousing stimulus. Moreover, in such a case, fear would be more intense and would last longer than in the case of one whose adrenalin release was adequate to meet the situation . • Proneness to fear is a common symptom in pathologies resulting from hypofunction of the adrenals. In the humoral theory, proneness to fear was also attributed to the insufficiency of a humor in the blood, namely, the melancholia, though in a somewhat different manner. A lack of this thick earthy element would result in the blood being too watery and thus easily cqngealable by the cooling effect of fear. This would result in an insufficient production of spirits in the heart, with a resulting inability of the organs to meet the situation, an inability to the evil, an inclination to run away, or, if the fright was sufficient, a paralysis, shaking of the knees, etc., all of which would increase the fear and make it last longer. To quote Aristotle again: " . . . those animals are more timid whose blood is very watery: for water is congealed by cold: and for this reason also animals lacking blood are more timid than animals with blood . . . and when terrified they remain motionless." 116 St. Albert's teaching on the subject is as follows: Animals whose natural humor is very watery and capable of being quickly cooled, are of greater temerity, since fear cools the body on account of the transit of the blood and heat and spirit. If then the humor is congealed, the heat to dissolve it does not quickly return; therefore such animals remain frightened and motionless for a long time. Hence the animal whose heart is of such a temperament, that is, could and watery, suffers frequently from any slight cause a paroxysm of fear. For cold water is quickly congealed; wherefore an 118 Loc. cit. EFFECT OF BODILY TEMPERAMENT 498 animal without blood has greater fear than one with blood, so that such animals become motionless when frightened. 111 St. Thomas says on the matter: As to the appetitive movement of the soul, fear implies a certain contraction, the reason of which is that fear arises from the imagination of some threatening evil which is difficult to repel. But that a thing is difficult to repel is due to lack of power . . . and the weaker the power is, the fewer the things to which it extends. Wherefore from the very imagination that causes fear there ensues a certain contraction in the appetite. It is in resemblance to this contraction, which pertains to the appetite of the soul, that in fear a similar contraction of heat and vital spirits towards the inner parts takes place in regard to the body .118 As the Philosopher (Aristotle) says (De Problem., xxvii, 3), although in those who fear, the vital spirits recede from the outer to the inner parts of the body, yet the movement of vital spirits is not the same in those who are angry and those who are afraid. For in those who are angry, by reason of the heat and subtlety of the vital spirits, which result from the craving for vengeance, the inward movement has an upward direction. Wherefore the vital spirits and heat concentrate around the heart, the result being that an angry man is quick and brave in attacking. But in those who are afraid, on account of the condensation caused by the cold, the vital spirits have a downward movement, the said cold being due to the imagined lack of power. Consequently the heat and vital spirits abandon the heart instead of concentrating around it, the result being that a man who is afraid is not quick to attack, but is more inclined to run away.119 . . . in fear there takes place a certain contraction from the outward to the inner parts of the body, the result being that the outer parts become cold. For this reason trembling is occasioned in these parts, being caused by the lack of power in controlling the members, which lack of power is due to the want of heat, which is the instrument whereby the soul moves those members. 120 In fear, heat abandons the heart, with a downward movement: hence in those who are afraid the heart especially trembles, as also those members which are connected with the breast where the heart resides. Hence those who fear tremble especially in their speech, on account of the tracheal artery being near the heart. The lower n• Op. cit., XII, t. 2, cap. 1. 118 Summa Theol., I-II, q. 44, a. 1. 110 Ibid., ad 1. uo Ibid., a. S. 494 LEO M. BOND lip too, and the lower jaw tremble, through their connection with the heart, which explains the chattering of the teeth. For the same reason the arms and hands tremble, or else because the aforesaid members are more mobile. For which reason the knees tremble in those who are afraid. 121 On the part of the bodily instruments, fear, considered in itself, is always apt to hinder exterior action, on account of the outward members being deprived, though fear, of their heat. 122 With regard to anger, we noted that Berman attributes proneness to this passion to the ability of the cortex section of the adrenals to secrete a sufficient amount of its hormone, "cortin," to offset the inadequate supply of adrenalin by the medulla section. If, when an animal is subjected to some feararousing stimulus, his adrenal cortex releases an abundance of cortin, his extensor muscles-the muscles of attack-become tense, his blood pressure, heart beat, nerve impulses, etc., are sufficiently accelerated to enable him to repel the threatened evil and instead of protracted fear and an inclination to escape, there is produced anger and an impulse to face and overcome the threatening evil, which would be characteristic, as he mentions, of such animals as bulls, lions, etc. This produces a particular type of anger, a sudden, vehement anger, lasting only long enough to repel the evil. Another type of anger, a slowly mounting, but strong and long enduring one, is attributed, as we shall see later, to other hormones. In the humoral theory, this quick, vehement anger was attributed to an excess of cholera; more slowly rising, longer lasting anger was due to an excess of the melancholia in the blood as represented by the presence in the blood of small fibrous particles of melancholia which underwent in anger a gradual heating up process and a correspondingly slow cooling off process. When heated, these fibers stimulated the blood and the heart and caused an increased production of warm spirits with a corresponding rise and intensification of anger. As Aristotle says: 111 Ibid., ad 8. 12 " Ibid., a. 4. EFFECT OF BODILY TEMPERAMENT 495 Those animals whose blood is rich in fibrin, (melancholia) have a more earthy temperament, and habitually become angry and are prone to fury. Anger produces heat, but solids, once they are heated, give off more heat than do liquids. The fibrin is solid and earthy, and so acts as a sort of foment in the blood, and it causes a heating up of the blood by anger, whence it comes about that bulls and boars are wrathful and are prone to rage.l23 Albert says on this subject: Sometimes, moreover, there are in the blood of some animals small hair-like bodies (fibrin) dispersed through the blood and these animals have an earthy blood, which when it is heated, holds the heat for a long time. Therefore these animals are very prone to anger, and retain their anger a long time, for anger moves the heat because of the desire for revenge, in which the heart is enlarged, giving off heat and blood and spirits. Such· blood remains hot a long while because earthy material holds heat longer than does the humidity of water. The fibrous earthy bodies which are in the blood of such animals, become in times of anger like coals of fire; this is the reason for the common saying, that the bull and the boar are animals exceedingly prone ·to anger, and they become confused and wild when angry because they have many such fibrous bodies in their blood. 124 St. Thomas describes the quick, effervescent due to the cholera: type of anger Now the impulse to passion may arise either from its quickness, as in choleric persons or from its vehemence, as in the melancholic, who on account of their earthy temperament are most vehemently aroused. 125 ... a man is prone to become angry because of his choleric temperament, and the cholera moves more swiftly than any other humor; for it is like fire.126 Damascene says (De Fide Orth. ii, 16) that anger is fervour of the blood around the heart, resulting from an exhalation of the cholera. And because the movement of anger is not one of recoil, which corresponds to the action of cold, but one of prosecution '"" Loc. cit. cit., XII, t. 2, cap. 1. 1 .. Op. 10 " 118 Summa Theol., 11-11, q. 156, a. 1, ad 2. Ibid., 1-11, q. 46, a. 5. 496 LEO M. BOND which corresponds to the action of heat, the result is that the movement of anger produces fervour of the blood and vital spirits around the heart, which is the instrument of the soul's passions. And hence it is that, on account of the heart being disturbed by anger, those chiefly who are angry betray signs thereof in their outer members. For as Gregory says (Moral, v. 80) the heart that is inflamed with the stings of its own anger beats quick, the body trembles, the tongue stammers, the countenance takes fire, the eyes grow fierce, they tha.t are well known are not recognized.127 There are, naturally, many differences in detail between the precise manner of functioning ascribed to the hormones in the physiology of the passions and that attributed to humors, but in fundamental notions, the likenesses are substantial and striking: e. g. the nature of the blood as the chief determinant of inclinations to passions, due, in the endocrinal theory, to its hormonal content, in the humoral theory to its humoral content; the physiological functions through the medium of which both hormones and humors are considered to exert their influence on the passions, viz., blood pressure, heart action, muscle tension, nerve excitation, etc.: and in a general way, the manner in which the hormones and humors function in this mediation; the notion of physiological speed and heat and expansion in the " warm " passions such as anger, and lack of heat, contraction, etc., in the" cold" passions like fear. With regard to the actual manner of functioning of the hormones in intellectual activity, the endocrinologists are, as we have seen, very vague. They know from observation that greater or less mental ability, speed of mental reaction, etc., are in way dependent upon and correlated with over- or undersecretion of such hormones as thyroxin and adrenalin, but as to just how or why this is so, only a few of them even venture an explanation. Berman, as already noted, would attribute the intensification of mental activity in dangerous situations to an increased electrical conductivity of the brain cells, brought about by an increase in thyroxin and adrenalin secretion, which would result in an increase of speed with which the 111 Ibid., q ..48, a. ft. EFFECT OF BODILY TEMPERAMENT 497 electrons would fly through the cells, from which would result in turn an increased speed in sensation and ideas. As to the functioning of the pituitary secretions in determining such mental qualities as soundness and accuracy of judgment, ability to coordinate knowledge, etc., he is silent. He simply states the fact, presumably arrived at by observation of mental phenomena accompanying hypo- or hyperfunction of the pituitary. Actually, little more is known than the fact that under- or oversecretion of certain hormones creates some· sort of disposition in the chemistry of the brain which influences the quality and type of mental reactions. 'Jrhe ancients and medievalists knew this much and some of them, a good deal more besides. For Aristotle and his followers, the data which the mind used in forming its concepts were tihe sensible images impressed upon the internal sense organs of memory, imagination, etc., from which they were abstractexclusivel., upon the principal " loci theologici," Sacred Scripture and the dogmatic definitions of the Church, he coordinates the essential truths of the Catholic Faith under the three-fold heading of God, Creation, Oneself. The exposition of Dogma and Moral is very simply unified, yet Mr. Sheed's treatment of detail is exquisite. He teaches but does not fatigue. He makes no promises of explaining away mystery, or of freeing the reader from any mental effort, but he does very emphatically help the willing reader to see more clearly the light and beauty and the wonder of the revelation of God. This reviewer was especially impressed by the first two sections. It seems to him that the recession in the third section from the very high standard of the first two parts stems principally from the magnitude of the task undertaken by the author. The very extensiveness of the virtues and gifts of the Holy Ghost is apt to impair the unity and simplicity of exposition and also occasion more opportunities for statements not in keeping with the Thomistic tradition which Mr. Sheed implicitly reveres. Precisely because of our intense admiration for and express commendation of this work and me'l"ely to clarify and not to criticize, a few observations are in order. Defining goodness (p. 100), Mr. Sheed seems to impose some form of creation as absolutely incumbent upon divinity by using the words "spread outwards." He infers in an illustration (p. 159) that Adam and Eve by reason of the fall lost their freedom of will, in face of passion; yet he takes pains in the following paragraph to assert that freedom. He says that " with Faith there enters the soul the whole of our supernatural 530 BOOK REVIEWS equipment " (p. 355) , rather than with sanctifying grace. He places Temperance and Fortitude (p. 360) in the will rather than in the concupiscible and irascible appetites. In discussing law (p. 369) , it becomes a matter of will, not reason, and generally throughout this section there is a looseness of expression implying Voluntarism though the explanations invariably are couched in terms of reason and intellect. There is definite contradiction in countenancing the co-existence of a natural habit of sin with the supernatural habits of grace and virtue in one and the same faculty (p. 394.) Finally, the virtue of chastity (p. 400) is identified with mere physical virginity. Even with these reservations we most heartily recomme11d " Theology and Sanity " not only to priests and seminarians but to all who are looking for an illuminating exposition of central Catholic thought above the simple level of the Catechism. CLEMENT KEARNEY, Dominican House of Studies. Washington, D. C. 0. P. BRIEF NOTICES Eve and the Gryphon. By GERALD VANN, O.P. Oxford: Blackfriars Publications, 1946. Pp. 71. 6/-. The Gryphon is defined as a fabulous creature half lion, half eagle. In these conferences given by Father Vann, 0. P. to St. Joan's Alliance, Oxford, on the vocation of woman in the modern world, the inspiration that women must be to men is brought forth with this underlying current that while " the lips are the lips of a woman, the smile is the smile of Christ." In other words, a woman's vocation as a wife and a mother, is to lead men to Christ. Through prayer and detachment women must learn to love the world in God and desire to serve it. They must fulfill in themselves the vocation of tears for if they have the heart of Christ they will have the compassion of Christ. Four conferences are contained in this brief but most provocative study. Through St. Catherine of Sienna women can learn of prayer, detachment, and what it means to have the heart of Christ. Through St. Monica they learn the secret of tears and compassion. The Mother of God will tell them of the vocation of Motherhood, and Eve who turned things to herself through selfishness will tell the modern woman that she must turn things to Christ, that her eyes must be fastened on the Gryphon, Christ, Who in loving the world died for it. No woman, eager to fulfill her role as wife and mother, can read these talks of Father Vann without being moved to the sublimity of her vocation. The lay apostolate will open up to her the necessity of a detachment whereby the more she loves God the more will she love others because the more will she share in God's love of others. False love will be stripped away and in the true love of others, because of the love of God, women will achieve their vocation. Our contemporary world in seeking the emancipation of women has been led into strange and erroneous interpretations of the role married women must play in life. This book is an exhilarating breath of the role theology plays not with the facts of married life but with the theological principles of marriage. It contains a vital spiritual message and uplift for all married women. The Meaning of Existence. By CHARLES DUELL KEAN. New York: Harper, 1947. Pp. 222, with index. $3.00. This work, which the author acknowledges to be written in the tradition of Kierkegaard, is an appeal for the reconstruction of the modern world 531 532 BRIEF NOTICES through a return to the meaning of existence exemplified in the Gospels. The factors in such a reconstruction, according to the author, are on three levels: history, intellect, and existence. History, where man meets nature and his fellow-men, is taken as it " properly refers to the institutional nature of human affairs." (p. 38) Here man finds himself a servant, formed by fate and responding by necessity. The intellect attempts to transcend history by the categories of memory, anticipation, critical judgment, and creativity. But in the end, the struggle to dominate history only overlays it with intellectual categories that, like Kantian forms, do not meet historical r-, Francis de, International Community According to --.
