The Thomist 63 (1999): 343-401 THE NATURE AND GRACE OF SACRA DOCTRINA IN ST. THOMAS'S SUPER BOETIUM DE TRINITATE l.AWRENCEJ. DONOHOO, 0.P. Dominican House of Studies Washington, D.C. I NQUIRIES INTO THE meaning and function of sacra doctrina in St. Thomas's thought have long centered on the pregnant yet cryptic opening question of the Summa Theologiae. Relatively little attention has been devoted to its treatment in his exposition of Boethius's De Sancta Trinitate. 1 Yet this early text, devoted to questions of theological and philosophical method, explores with unusual sophistication the various dimensions and tasks of sacra doctrina: a knowledge dependent on revelation and reason; the relationship between faith and reason; the work of reason within and apart from faith; justifications for belief; and the psychological, epistemological, and theological grounds for the complementarity between faith and reason. This study will explore these various facets of sacra doctrina in the De Trinitate in order to establish how Thomas, toward the beginning of his career, laid down an intermeshing foundation for philosophy and theology in a work all the more valuable for 1 All references to St. Thomas's opusculum on the De Sancta Trinitate (hereafter De Trinitate or In Boet. de Trin.) depend on the critical edition of the Leonine Commission, SuperBoetium deTrinitate (Rome: Commissio Leonina, 1992).

Translations and paraphrases of the last two questions rely on Armand Maurer, St. Thomas Aquinas: The Division and Methods of the Sciences.

DONOHOO being the sole thirteenth-century commentary on Boethius's text. 2 What emerges in this daring exposition, which supported the edifice of his thought to the end, is the construction of an overarching science-a wisdom-that embraces a "meta-philosophy" and a "meta-theology," in which neither component, while retaining its own identity and its own acts, can be understood without the other. A study of this text also reveals that much of the teaching on sacra doctrina in the Summa Theologiae is simply a borrowing or rearrangement of ideas already advanced in this early opusculum. 3 In question 1, Thomas examines theology's contribution to philosophy. 4 How does a thinking steeped in faith know the 2 Jean-Pierre Torrell, Saint Thomas Aquinas, vol. 1: The Person and His Work, trans.

Brill, 1992), is especially helpful for studying the relationship of the De Trinitate to the Commentary on the Sentences (39-40; 48-49, 55-58). For an extensive list of texts in the Thomistic corpus treating the question of theological method, see Yves Congar,A History of Theology, trans. Hunter Guthrie (Garden City, N.Y.: Doubleday, 1968), 91-92. 3 For an alternative approach that detects a gradual development in Thomas's concept of sacradoctrina from the Sentences through De Trinitate and the Summa contra Gentiles to the Summa Theologiae, see Corbin, Le chemin de la theologie, 64-107. A textual-systematic approach is in any case recommended in the presence of the quaestio which, shaped by discrete arguments and responses, lends itself to the interpreter's toil of reworking its parts into a systematic whole. 4 The structure of the Super Boetium de Trinitate is simple and meticulous, if incomplete. Following Boethius's text (preface and two chapters), Thomas's opusculum is comprised of an introduction (pro/ogus), three brief commentaries (expositio prohemii, expositio capituli primi, and expositio capituli secund1), and six questions marked off in three groups of two questions which follow each expositio. The literal commentaries closely follow Boethius's SACRA DOCTRINA IN THE DE TRINIT'ATE 345 limits and limitations of philosophy in a way hidden from philosophy itself? Furthermore, how does theology clarify the nature of philosophical thinking by situating human knowing in a larger field of knowers? Theology, reaching over to interpret philosophy from a revelatory perspective, finds that its own self-understanding is broadened in the process. In question 2, Thomas examines philosophy's contribution to theology. How does knowledge that arises solely from reason and that is placed before, within, and alongside the knowledge that proceeds from faith contribute to building up a body of knowledge whose content represents a human assimilation of divine truth? Moreover, how can this knowledge assist theology even as it retains its own nature and methods? 5 In its task of converting belief into sacra doctrina, philosophy both becomes something else and remains itself as theology's companion, counterpart, and competitor. Question 3 plumbs yet deeper to uncover the principles and nature of sacra doctrina embedded in faith, along with offering a "theology" of philosophy that places both sacred science and secular knowledge within the ambit of the natural desire for God. Finally, question 5, within the context of sorting out the various sciences of natural reason, articulates the basis of faith, itself the basis of sacra doctrina, in God's revelation. The major issues introduced in the prologue are largely raised and resolved in these four interrelated questions. We cannot do better than to trace Thomas's argument textually, for he arranged his work to unfold in accordance with the nature of the subject matter as well as with Boethius's text. 6 However, while Boethius employed a recondite style in order to exclude unworthy readers, text, while the six questions probe more fully issues raised in the expositiones, as the introductory remarks to questions 1, 3, and 5 indicate. 5 Unless otherwise indicated, "theology," "divine science," and "sacred doctrine" are used interchangeably in this study in both their Latin and English forms to refer to the discipline which, following upon revelation and presupposing faith, investigates God and his creation as it is related to him. "Theology" is to be distinguished particularly from theology as a branch or dimension of metaphysics, and "divine science" is to be contrasted with God's own science or knowledge. 6 The coincidence of systematic and textual order is helped by Thomas's recognition that Boethius proceeds theologically, that is, he begins with the absolute starting point of the Trinity, which only faith reveals (In Boet. de Trin., prol. [75; 3-4]). 346 LAWRENCE]. DONOHOO Thomas's work, by its very nature as exposition and commentary, seeks to illuminate and develop Boethius's teachings even to the point of clarifying the character of his veiled and obscure style.7 The result is an exposition, concise yet comprehensive, that skillfully images its prototype because a master is commenting on a master. 8 I. THE PROLOGUE: A QUEST FOR THEOLOGICAL METHOD First statements are usually important in works that treat of first things, and De Trinitate is no exception: "The natural gaze of the human mind, burdened by the weight of a perishable body, cannot fix itself in the first light of truth, by which everything can be easily known." 9 Presuming Thomas's Aristotelian psychology of powers and nature, his relatively optimistic assessment of human nature, and above all his fleshly anthropology, one might well be startled by the spiritualist cast of this statement and its propensity to judge human nature by angelic or divine standards. Since an interpretation that finds Thomas succumbing to angelicism or so-called Platonism must be excluded by the most rudimentary familiarity with his epistemology and anthropology, we must look for other explanations. Textually, the opening statement anticipates Boethius's preface, which expresses disquiet in the face of the awesome mystery being approached. It provides a counterpoise to the optimism, absent in Boethius, which is expressed in the epigraph quoting Wisdom 6:22: "I will seek her out from the beginning of her 7 In Boet. de Trin. (69; 7); pro!. (75-76; 3-6); exp. proh. (79; 11). For Thomas's discussion of the prudent use of obscure speech in theological writing, see In Boet. de Trin., q. 2, a. 4 (100-102; 51-55). 8 Thomas's work as exposition and commentary is itself an image of Boethius's text, which Thomas understands as purporting to image God's own knowledge. For he interprets Boethius's opening statement as identifying the efficient cause of the text as principally God's divine light and secondarily the author's mind (In Boet. de Trin., exp. proh. [77; 8]). Thus the De Trinitate as text images what it teaches, namely, a sacred teaching rooted in God's revelation and transmitted in a tradition. 9 "Naturalis mentis humane intuitus, pondere corruptibilis corporis aggrauatus, in prime ueritatis luce, ex qua omnia sunt facile cognoscibilia, defigi non potest" (In Boet. de Trin., pro!. [75; 3]; see also ibid., q. 1, a. 1, ad 4). 347 SACRA DOCTRINA IN THE DE 7RINITATE ° birth, and will bring the knowledge of her to light." 1 Further, it responds to Sacred Scripture by paraphrasing the anthropology of Wisdom 9: 15: "For the corruptible body is a load upon the soul, and the earthly habitation presseth down the mind that museth upon many things. " 11 In this way Boethius's apprehension is both acknowledged and balanced by two scriptural texts respectively concerned with the light of human wisdom and the weight of our corporeal nature. This juxtaposition is reinforced rhetorically through a series of contrasts: aggrauatus and luce, facile and non po test, naturalis intuitus and corruptibilis corporis.12 Systematically, the contrast presents the two poles that govern all six questions of the De Trinitate: the lowly human mind and the human nature it illumines, and the transcendence of the Trinity as ultimate object and end of the graced human intellect's desire. The brilliance of Thomas's opening remark appears more clearly when understood as not simply confirming a source of revelation, but also as interpreting the opening statement of Aristotle'sMetaphysics-the text on first principles which likely represented for Thomas the finest achievement of human reason. As a commentary on Aristotle's bold assertion that all human beings desire to know, the opening statement of the De Trinitate, without denying the doctrine of desire, inscribes the believer's experience of epistemological disappointment in the capacity of the human intellect to know the highest truths by its own power. This initial declaration, then, not only balances the epigraph by tempering Scripture with Scripture, it also mediates between Jerusalem and Athens by moderating the optimism of human thinking with a sobriety that leans on divine wisdom. We know from faith that we do not know from nature the first truths except as through a mirror darkly. In an imbrication of the Socratic mood, God's word gives us knowledge of our ignorance 10 "Ab initio natiuitatis inuestigabo et ponam in lucem scientiam illius" (In Boet. de Trin., pro!. [75; 3]). 11 Douay Rheims version. "[C]orpus enim quod corrumpitur adgravat animam et deprimit terrena inhabitatio sensum multa cogitantem" (Biblia Sacra: Iuxta Vulgatam Versionem, vol. 2 [Stuttgart: Wiirttembergische Bibelanstalt, 1969]). 12 See Thomas's discussion of the necessity of veiling theological discourse as evidence of his rhetorical sensitivities (In Boet. de Trin., q. 2, a. 4 [100-102; 51-55]). 348 LAWRENCE). DONOHOO in a way and to a depth unknown to philosophy. Hence the De Trinitate, as a query into our ignorance, attempts to bridge the gap between the infinite and finite in the realm of knowledge and to set this knowledge against the enlightening matrices of divine and angelic knowledge, human participation in this knowledge, and other kinds of human knowing. In this pursuit of somehow knowing what it cannot know and in ways it cannot know, the human mind is directed both into itself in the reflective analysis that ponders its own act and above itself to the highest Knower for whom we are partly suited in our nature and our knowledge, both by nature and by grace, already now and forever in glory. 13 The opening statement of the prologue introduces an argument that points to the natural limitations of the human mind ascending to a knowledge of God through knowledge of creatures. God compensates for the human incapacity to know him adequately by providing "another, safe way of knowing ... through faith. " 14 Although this passage does not conclusively establish that per {idem means "through the mediation of faith" rather than "through faith itself," a subsequent statement clarifies that this knowledge is based on faith but not identical to it. 15 A basic distinction between philosophical and theological knowing follows: philosophers consider creatures before the Creator, presumably in their ascent to him, while theologians first consider the Creator by virtue of God's revelation. This distinction punctuates the De Trinitate's major theme of the limits and possibilities of knowledge variously addressed in the following six 13 "From the Vlth century text [of Boethius], we pass to the XIIIth century commentary [of Thomas] in which the questions dealt with reveal perhaps the topmost point reached by XIII th century's critical reflexion upon itself" (Chenu, Toward UnderstandingSaintThomas, 278). 14 "Et ideo Deus humano generi aliam tutam uiam cognitionis prouidit, suam notitiam mentibus hominum per fidem infundens" (In Boet. ck Trin., pro!. [75; 3]). For a similar argument, see ibid., q. 3, a. 1 (107-8; 65-67). The use of via, when compared with its pivotal use in the arguments for God's existence (STh I, q. 2, a. 3), suggests that Creator and creatures share a common task in bridging the chasm that separates them. 15 "[C]ognitionis desuper date principium est prime ueritatis notitia per fidem infusa" (In Boet. ck Trin., pro!. [75; 3]). Like the opening article of the Summa Theologiae,the prologus thus distinguishes, if not sharply, between truths of faith and theological reflection following upon them. However, the emphasis here, in contrast to the Summa, is on knowledge of God rather than salvation. SACRA DOCI'RINA IN THE DE TRINITATE 349 questions.16 More immediately, it elucidates Boethius's theological method whose point of departure is "the supreme source of things, namely the Trinity of the one God," and so establishes this knowledge as a pursuit of divine knowledge dependent on faith, rather than the knowledge of faith itself.17 Finally, this architectonic distinction between theology and philosophy introduces a "meta-theology" or wisdom that overarches both knowledge based in faith and natural knowledge by defining each in opposition to the other, but in such a way that their mutual assistance is implied in their passing trajectories between God and creation. 18 Such in fact appears at once in reflection on the loftiest and most abstruse mystery of the faith. Thomas follows Boethius's example of comparing and contrasting the divine processions with created ones. Is this analogy a divine teaching or a human one? It appears to be both: certain scriptural texts are cited to indicate its revelatory lineage,19 yet these analogies also serve as concepts for ordering human thinking that Thomas finds at the core of Boethius's own theological vision. In a prefiguration of the Summa Theologiae'sown structure, Boethius's consideration of uncreated and created processions is seen by his commentator as the key for opening up his entire theological scheme of procession and restoration. 20 The rapid path from reflection on the highest to reflection on the whole in order to understand the highest suggests that both thinkers understand that speech about 16 Even a question as metaphysically abstruse as whether two bodies can exist in the same place is the locus of a teaching on the limits of reason (In Boet. de Trin., q. 4, a. 3, ad 1 [129-30; 105-6]). 17 "Hunc ergo ordinem sequtus Boetius, ea que sunt fidei tractare intendens, in ipsa summa rerum origine principium sue considerationis instituit, scilicet trinitate uni us simplicis Dei" (In Boet. de Trin., pro!. [75; 4]). 18 Thomas may have been prompted here by Aristotle's deployment of a meta-wisdom in the philosophical domain that, by defining the subject matter of first philosophy, is situated both within and beyond it. See Aristotle, Post. Anal. 1.9-12; and Aquinas, I Post. Anal., lect. 17-21; Aristotle, Metaphys. 1.2; 6.1; and Aquinas, In Metaphys., prooemium. 19 Thomas cites Ephesians 3:15; Colossians 1:15; and Proverbs 8:22. 20 In Boet. de Trin., pro!. (76; 5). As presented in the De Trinitate, Boethius's tripartite scheme is the Trinitarian God, the procession of good creatures from the good God, and the renewal of creatures through Christ. The Summa Theologiaecombines Boethius's first two parts in the Prima Pars, and then divides his last part into the "renewal of creatures" (Secunda Pars) and "through Christ" (Tertia Pars). All of this is prefaced by a preliminary treatment of sacra doctrina (STh I, q. 1, a. 1) that parallels Boethius's preface. 350 LAWRENCE J. DONOHOO the Creator presupposes speech about the created. For this reason, the statement that God is treated first in theology must be interpreted with a certain elasticity. Turning to the question of method, Thomas leans on the unimpeachable authority of St. Augustine to introduce the distinction between leaning on authorities and following reason. Boethius's preference is reason: "The aim of the present treatise is to clarify the mysteries of faith, as far as this is possible in the present life." 21 Thomas emphasizes that this rational quest for understanding the highest things presupposes faith by fortifying Augustine's authority with Scripture: the way of reason is reserved to the wise individual who investigates knowledge of the Trinity "which men of former times accepted on authority alone." 22 Depending on a kind of thinking of which only the few are capable, the method of reason embodies a special kind of knowing conversant with the created order that transposes its insights into understanding of divine matters. 23 The argument clearly implies that those who take the truths of faith further along the path of understanding are to be praised above those who simply believe on the basis of authority. This suggests that divine revelation not only allows for but actively reveals the truth that the deepening of one's knowledge of revealed truths by enlisting human reason is to be encouraged. Such a conclusion is reinforced by the prologue's closing image of the wise man, borrowed from Job, that makes for a fitting inclusion with the epigraph: "He has searched the depths of rivers, and hidden things he has brought forth to light." 24 It is also braced on the level of human reason by a shrewd observation on Boethius's writing for the understanding few. The difficulties 21 "Finis uero huius operis est ut occulta fidei manifestentur quantum in uia possibile est" (In Boet. de Trin., pro!. [76; 6]). 22 "quam antiqui sola actoritate asseruerunt" (In Boet. de Trin., pro!. [76; 6]). Ecdesiasticus 39: 1 is cited. 23 The following brief commentary on the preface to De Sancta Trinitate provides evidence of this by employing the doctrine of fourfold causality, unfolding various forms of argumentation, and acknowledging the limitations of its own human reasoning (In Boet. de Trin., exp. proh. [77-79; 8-12]). 24 "Profunda fluuiorum scrutatus est et abscondita produxit in lucem" (In Boet. de Trin., pro!. [76; 6]). Job 28:11 is cited. SACRA DOCTRINA IN THE DE TRINITATE 351 set before the reader are the locks that either bar him from reading the text, or the occasion for summoning ingenuity and patience so as to release them. 25 In fact, Thomas has made the reader's task less arduous by sounding all the major themes of his text in his sparse introductory remarks. Both in his brevity and in his clarity he continues along the path Boethius marked out in the human quest for understanding the deep 'things of God and his creation. Already Thomas has given the major outlines of what he will soon call sacra doctrina: a faith-based inquiry into the highest cause, and the implications of this cause for everything else. II. QUESTION 1: HUMAN KNOWLEDGE AND ITS LIMITS In continuity with the theme of the prologue, the first article of the De Trinitate shows that the human mind's resources are sufficient for it to know the truth without a new divine illumination. The nature of the human mind is elucidated as the power that is principally engaged with the acts of believing, thinking, and theologizing. In the first part of the responsio, reason and revelation, represented by Aristotle and Scripture (Ps 4:7), respectively, join together to establish against Avicenna that the agent intellect is a power of the soul. 26 The conclusion that the active and passive powers working together are adequate for the intellect to perceive the truth leads to the second subargument, which demonstrates that the intellect's power extends to certain intelligible truths that fall within its proper domain. This judgment about natural truths is apparently made by reason. But the companion claim that other truths-among them the truths of faith-lie beyond the capacity of reason and are only known by a divine illumination "supplementing the natural light," obviously depends on premises that arise from 25 "ut ea que in hoc libro scribuntur tantum sapientibus colloquantur, qui hec intelligere poterunt, sicut est auctor ipse et ille ad quern liber conscribitur, alii uero, qui capere intellectu non possunt, a lectione excludantur: non enim libenter leguntur que non intelliguntur" (In Boet. de Trin., exp. proh. [79; 11)). The argument of ibid., q. 2, a. 4 (100-102; 51-55) is also pertinent to this discussion. 26 Thomas's awareness of Aristotle's ambiguity on this question, which occasioned Avicenna's position in the first place, is captured in his careful formulation: "uerba Philosophi ... magis uidentur sonare" (In Boet. de Trin., q. 1, a. 1 [82; 16)). 352 LAWRENCE J. DONOHOO faith. 27 Finally, a concluding subargument, also relying on revealed principles, shows that divine Providence offers ordinary guidance to all created natures by directing their powers to their respective acts, and that the human mind therefore requires this divine activity for its natural functions as well. 28 To varying degrees, then, the various subarguments enlist both revelation and reason to defend the human intellect's capacity to know truth on the strength of its own nature, albeit a nature dependent on God's creative and providential causality. Clearly, a special divine illumination is assumed here for demonstrating the naturalness of human knowing inasmuch as the argument depends in large part on principles that derive from faith. Revelation offers reason its resources to help it to understand its own nature as well as its limitations as a self-possessed power. For only in a theology of creation that points back to the intentions of the Creator who makes, shapes, and guides it in its acts does human reason find its ultimate articulation. To this end, Thomas intricately weaves an inductive argument of reason, working backward from activities to the nature and functions of the human intellect, with deductive arguments rooted in doctrines concerning the truths of faith and secondary causality. At first glance the argument's dependence on theological premises suggests that reason is inadequate to the task of accounting for itself. To be sure, Thomas joins revelatory principles to principles taken from natural psychology, anthropology, and epistemology in part because of the difficulty of the subject matter, 29 but his intention is also to advance a "theological psychology" that offers far more than reason can provide on its own. No contradiction is involved in the implication that the human mind needs a supernatural illumination to know adequately that it does not need a new illumination to know truth, for a more comprehensive theological approach to the argument does not negate its strictly philosophi27 "superaddito lumini naturali" (In Boet. de Trin., q. 1, a. 1 [82; 17]). 28 For a discussion of the agent intellect as an immediate participation in God's own light, see Jan H. Walgrave, "Die Erkenntnislehre des hi. Thomas von Aquin," in Aktua/itiit der Scholastik?, ed. Joseph Ratzinger (Regensburg: Friedrich Pustet, 1975), 30. 29 "multa inquisitione indigeat ad cognoscendum quid est intellectus" (In Boet. de Trin., 1, q. a. 3 [87; 27]). SACRA DOCIRINA IN THE DE TRINITAIE 353 cal conclusions. Unable to account thoroughly for its own capacities and limitations, reason transcends itself by merging with faith in order to learn more about its nature than it can gain on its own. Hence the question of whether the human mind is adequate for its own act can be clarified more satisfactorily with the aid of faith, even if reason is taken beyond its own horizon. Paradoxically, reason comes to understand more adequately that it is self-standing by way of a meta-theology which, without calling attention to itself, sheds light on the human intellect by pointing to the radical conditions of its exercise and the limitations of its power. In other words, faith helps reason to see to what extent reason does not need faith-and to what extent it does. Asking whether the human mind can arrive at a knowledge of God, article 2 addresses the issue of human knowledge of divine matters. It follows the example of the preceding article both methodologically, by engaging faith and reason, and substantively, by clarifying the natural limits of human knowing in its pursuit of the ultimate cause of all things. This clarification is achieved by contrasting the human intellect to the divine intellect and angelic intellects with respect to the way one knows oneself and other beings. The argument centers around knowledge as possession of the form known. Something can be known either through its own form or through the form of something similar to itself. Further, there are two ways that something is known through its own form: either through the form which is the being itself (as God knows himself through his essence) or through a form derived from the reality (as the human intellect knows the stone through its abstracted form). Neither of these ways, however, applies to the human intellect's knowledge of God in our present state. For knowing God through the form that is his essence, which constitutes the beatific vision, is unavailable to an intellect that for now can only know anything by abstracting its form from the senses. As for knowing something through a form that is derived from it, any likeness imprinted by God in the intellect would be created and hence inadequate for reflecting his infinite essence. Finally, knowing God through purely intelligible forms is also ruled out because the human intellect in this world is naturally related to images. Hence God can only be known 354 LAWRENCE J. DONOHOO through the form of something similar to himself, namely through the form of his effect. Some effects are equal to the power of their causes, and provide knowledge of the cause's essence; other effects are unequal, and can only provide knowledge of the existence of the cause. Since all effects fall short of God, the human intellect is only able to conclude that God exists. However, Thomas turns from Aristotle to Dionysius to widen access to knowledge of God through the three ways of causality, supereminence, and negation. As with the first article, principles arising from faith are indispensable for this argument's attemptto investigate the power and limits of reason. Even in the terms in which it is framed, the primary question of whether the human mind can know God presupposes knowledge of him not available to human reason. Reason contributes epistemological and psychological principles borrowed from Aristotle;30 faith provides doctrines which support an intellectual penetration of mysteries concerning the beatific vision and the nature of God and of angels. By situating the human intellect within a larger field of suprahuman and human knowers enjoying the vision of God's essence, Thomas presents a theological epistemology of the human mind that provides knowledge of ways of knowing that do not or do not yet apply to us. The net effect is a complex interpenetration of philosophy, faith, and theology that establishes limits for the operations of reason in this world. 31 But can the truths of faith provide the human intellect with a knowledge that transcends the capacities of reason? For knowing the limits that are naturally set for human reason is already in some sense to have transcended these limits in order to know them as such. Thomas addresses this question toward the end of the responsio in the affirmative, but in a way that accents the via negativa: directs our attention, among other references, to De Anima 3.7; Post. Anal. 2. 7-10. Here, as throughout the work, he provides an extensive list of sources (Faith, Reason, and Theology, 21-22). 31 This argument is not complete, for Thomas will later show that revelation, in the act of revealing the need for it, instructs natural reason in the limits of its intellectual powers (In Boet. de Trin., q. 3, a. 1 [106-9; 63-70]). See also SI'h I, q. 1, a. 1, and ScG I, c. 5. 30 Maurer SACRA DOCIRINA IN THE DE TRINITATE 355 The human mind receives its greatest help in this advance of knowledge when its natural light is strengthened by a new illumination, like the light of faith and the gifts of wisdom and understanding, through which the mind is said to be raised above itself in contemplation, inasmuch as it knows that God is above everything it naturally comprehends. But because it is not competent to penetrate to a vision of his essence, it is said in a way to be turned back upon itself by a superior light. 32 As splendid and far-reaching as the teachings derived from faith may be, even they cannot circumvent the human intellect's present inability to attain to a knowledge of God through the divine form or through purely intelligible forms that bear a likeness to him. By means of the illumination of faith, however, the believing mind transcends itself by learning that God in himself remains unknowable to it in via. Reason, when elevated by the light of faith, "is raised above itself'' insofar as it breaks out of its own boundaries to learn that its natural boundaries are not exceeded by this new illumination. Whereas the first argument presented a theology based in faith showing reason its own limits, here a comparison of various knowers enables theology to know what limits even a supernaturally illumined human intellect encounters-and to know them precisely as limits. Article 3, investigating whether the intellect knows God before everything else, continues the exercise of applying insights rooted in both reason and faith to understand the nature and limits of the mind. Human unhappiness and disagreement about the nature of God provide initial evidence for a negative answer. The hypothesis that proposes that the human intellect first knows the divine light implanted within it is rejected, but this response requires a more extended analysis of what in fact the intellect first grasps by rneans of an inquiry into the mind's own act of knowing. In contrast to the first two articles, which borrow heavily from insights that depend on faith, article 3 relies largely on premises available to reason to bring the intellect to a 32 "In hoc autem profectu cognitionis maxime iuuatur mens humana cum lumen eius naturale noua illustratione confortatur, sicut est lumen fidei et doni sapientie et intellectus, per quod mens in contemplatione supra se eleuari dicitur, in quantum cognoscit Deum esse supra omne id quod naturaliter compreendit. Set quia ad eius essentiam uidendam penetrare non sufficit, dicitur in se ipsam quodarnmodo ab excellenti lumine reflecti" (In Boet. de Trin., q. 1, a. 2 [85; 22-23]). 356 LAWRENCE]. DONOHOO heightened self-awareness of what it need not know in order to know. 33 Knowledge begins with the object known; only then does the mind reflect on its act, and by means of the act reflect on its nature. Since reflexive knowledge presupposes simple knowledge of objects, the natural intelligible light which bestows the power of understanding need not itself be first understood. 34 A rather involved epistemology justifies this claim, which not only illuminates human knowledge of God but helps to preserve human knowledge from needless complexity. 35 Explicitly returning to Boethius's Trinitarian theology, article 4 argues for the impotence of reason in coming to a knowledge of the Trinity. Arguments from divine causality lead back only to the one God, who faith alone knows is the three Persons who mutually share in the work of creation. 36 This conclusion appears as the consummation of the entire question insofar as it directs all of its epistemological efforts toward the most sublime mystery of faith. Though the emphasis is on reason being taught its absolute boundary with respect to knowledge of God's intimate nature, we should observe what is doing the teaching: the faith-infused intellect which alone possesses knowledge of the Trinity. Hence article 4 points in two directions. On the one hand, by showing that natural reason is ignorant of God's innermost nature, it confirms the teaching of article 2 that inquiry based in faith deepens one's knowledge of God's utter transcendence as well as the human incapacity to penetrate to the vision of his essence or even grasp the conditions of its exercise. On the other hand, the intellect infused with faith, informing the natural intellect of what it alone knows of the Trinity, shows to what extent truths of faith 33 To be sure, theological reasoning also comes into play in accounting for the general knowledge of and desire for God present in everyone from the start, but this is secondary: "non ... oportet quod [Deus] sit primus in cognitione mentis humane, que ordinatur in finem, sed in cognitione ordinantis; sicut et in aliis que naturali appetitu tendunt in finem suum. Cognoscitur tamen a principio, et intenditur in quadam generalitate, prout mens appetit se bene esse et bene uiuere; quod tune solum est ei cum Deum habet" (In Boet. de Trin., q. 1, a. 3, ad 4 [88; 29]). 34 In Boet. de Trin., q. 1, a. 3, ad 1 (88; 28). 35 See Walgrave's excellent treatment of theology's contribution to epistemology in "Erkenntnislehre," 23-30. 36 In Boet. de Trin., q. 1, a. 4 (89-90; 31-32). SACRA DOCTRINA IN THE DE 1RINITATE 357 offer the believer an intimate and exclusive knowledge of God's nature. 37 Natural reason, however, is not simply on the receiving end. Alongside the double-edged growth in knowledge of God and knowledge of natural and faith-based ignorance of God is the contribution that reason makes to theology. For inquiry based in faith must know what reason can know by itself in order to distinguish such knowledge from what reason can know only through faith as well as what reason cannot know even with it. To begin with, natural knowledge of God varies from person to person relative to the capacity to apprehend adequately the relationship of causes to effects.38 Since this knowledge pertains to metaphysics, which in turn presupposes familiarity with the other theoretical disciplines, knowledge of God and of the character and limits of human knowledge presumes facility in the human sciences.39 While these disciplines do not pertain to theology per se, the kind of fundamental theological inquiry undertaken in these articles presupposes considerable knowledge of material logic, anthropology, psychology, physics, and metaphysics insofar as these disciplines help to identify the capacities and limits of the human intellect, especially concerning the highest truths. 40 In this way all human disciplines can assist natural reason in presenting the breadth of its capacities to faith. 37 For a discussion of the historical context of the question of the function and limits of reason and revelation in the debate over whether and to what degree human reason can aspire to natural knowledge of the Trinity, see Jarislav Pelikan, The Christian Tradition: A History of the Development of Doctrine, vol. 3, The Growth of Medieval Theology (600-1300) (Chicago: University of Chicago Press, 1978), 284-88. 38 "Et tamen unus cognoscentium quia est, alio perfectius cognoscit: quia causa tanto ex effectu perfectius cognoscitur, quanta per effectum magis appreenditur habitudo cause ad effectum" (In Boet. de Trin., q. 1, a. 2 [84; 22]). 39 "Human sciences" refers to disciplines dependent on natural reasoning in contrast to sacred science based on faith. 40 In Boet. de Trin., q. 3, a. 1 will later confirm this. There the third among five reasons for the necessity of faith is to make certain truths available to all: "propter multa preambula que exiguntur ad habendam cognitionem de Deo secundum uiam rationis: requiritur enim ad hoc fere omnium scientiarum cognitio, cum omnium finis sit cognitio diuinorum, que quidem preambula paucissimi consequntur; unde, ne multitudo hominum a diuina cognitione uacua remaneret, prouisa est ei diuinitus uia fidei" (108; 67). See also ibid., q. 6, a. 1, ad 2 (third part) (163; 65); and ScG II, cc. 2-4. 358 LAWRENCE]. DONOHOO In sum, question 1 offers a balanced assessment of the power and limits of human reason in general and especially in its investigation of first principles. Rejecting from the start the need for a special divine illumination for the functioning of natural reason, Thomas enlists conclusions of both faith and reason to set reason on its own two feet by defending its capacity-in one sense a tautology that supports his case-to accomplish what it has been empowered to do. But the following articles put a halt to a natural power that would aspire to an adequate knowledge of God, whether through his own essence (art. 2), or as the first truth known (art. 3 ), or in the form of a rational deduction of the Trinity (art. 4). At the same time, knowledge that is infused by faith helps the intellect to come to a deeper self-understanding of what it can naturally know and what it cannot, what its limitations are within the larger arena of divine and angelic knowing, the genesis of its own act of knowing, and its radical circumscription by faith's exclusive access to God's revelation. Theology's analytical forays into philosophical psychology, while remaining eminently theological, serve to clarify both the supernatural and the natural. Grounded in principles derived from God's revelation, the reflecting mind, infused by faith, is able to know what reason cannot know without the benefit of faith, and even to "know" something of what transcends reason illumined by faith. By reflection, illumined by revelation, the believer is able to look at his intellect, as it were, from the outside. III. QUESTION 2: MANIFESTING THE DMNE KNOWLEDGE The following sources of knowledge have been introduced in the first question: natural reason, particularly as it is exercised by the learned; the light of faith; the gifts of wisdom and understanding; and reason illumined by faith. These principles, which have explored the nature and limits of human reason, are directed in question 2 to examining the divine science rooted in revelation and pursued by the reflective human intellect insofar as it is illumined by faith and the gifts of the Holy Spirit. The thematic sequence from reason to divine science follows the logic that reason's nature and limitations must be probed before its SACRA DOCTRINA IN THE DE TRINITATE 359 resources can be applied to matters of faith. There is, to be sure, the suggestion of circular reasoning in this order of presentation: question 2 formally investigates, with reason's assistance, the nature of a theological science that has already served in question 1 as a source for examining human reason. But circularity is avoided if the arguments of question 1 defining nature and reason are understood as critical moments in divine science's work of distinguishing itself from natural reason in its quest for self-understanding. 41 A) Article 1: The Divine Permission for Human Inquiry into Divine Matters The fundamentally different perspective introduced by the second question can be appreciated by contrasting the issues raised in question 1, article 2 ("Whether one can attain to a knowledge of God") and question 2, article 1 ("Whether one should consider divine things by way of investigation"). 42 The earlier question, inquiring into the capacities of human reason to probe the highest cause, bypasses the issue of whether such questioning is permissible. Instead, it concludes that human reason requires the assistance of the new illumination of faith to arrive at an adequate knowledge of God. The second question, framed within the ambit of faith, asks the more basic "moral" question of whether revealed truths should be investigated. At the same time, this argument builds on the conclusions of question 1 insofar as the proposal that the mind should seek knowledge of God in the manner proper to it presupposes philosophical and theological insights into the nature and limits of human knowing. If the earlier question examined the possibilities of human knowing from the human perspective, the present question approaches the issue of limitations from God's viewpoint. More simply, the movement is from what we can know to what we 41 Or to paraphrase the teaching of In Boet. de Trin., q. 1, a. 1, the science by which we know is not that which we first know. 42 "utrum possit ad Dei notitiam peruenire" (80; 13) and "utrum diuina liceat inuestigando tractare" (92; 35) (my translation). 360 LAWRENCE]. DONOHOO should know. 43 However, by inquiring into God's will with respect to the human aspiration to know him, the question obliquely points to the paradox that its resolution presupposes sufficient knowledge of God's wishes. Thomas strategically places the moral question before the major epistemological concern of the following article: whether a divine science is possible. 44 This sequence indicates his departure from Aristotelian methodology, in which the first question to be asked would be an sit-in this case, whether a science of the particular matter at hand is possible. 45 However, that question can be deferred until article 2, because no matter what an inquiry into the precise nature of divine science yields, the revealed truths which ground any such knowledge cannot be denied. It is this prior faith which bids any investigation to reflect an antecedent reverence for God at the outset. For any inquiry arising from God's revelation is foremost a personal inquiry into the mode of response due him, a "person-to-person" encounter that appreciates the possibility of God's desire for privacy and searches natural wisdom, Christian teachers, and God's word itself for an answer. 46 43 Hall, The Trinity, 71-72; Elders, Faith, 43. In fact, the answer to the question this article poses was already adumbrated in In Boet. de Trin., q. 1, a. 2, which favors the human mind's advance in knowledge by the illuminations of faith, wisdom, and understanding. However, reason must also be aware of its limits; see, e.g., ibid., q. 4, a. 3, ad 1 (129-30; 105). 44 Only the last of seven objections in In Boet. de Trin., q. 2, a. 1 (92; 36) raises an epistemological objection to inquiring into divine matters. 45 Aristotle, Post. Anal. 1.1; Aquinas, I Post. Anal., lect. 2. For a helpful elucidation of the application of Aristotle's and Thomas's teaching to the postulation of a science, see William A. Wallace, The Role of Demonstrationin Moral Theology (Washington, D.C.: The Thomist Press, 1962), 17-20. Boethius is not cited here in support of Thomas's position, most likely because he was recognized as one of the tradition's strongest proponents of the use of reason in theology. His admonition, "si poterit rationemque coniunge," may be taken as the motto of his thought (Tractate 2, "Utrum Pater et Filius et Spiritus Sanctus," in Theological Tractates, ed. and trans. H. Stewart, E. Rand, and S. Tester, Loeb Classical Library [Latin], vol. 74 [Cambridge, Mass.: Harvard University Press, 1973], 36). 46 Johannes Stohr, "Die Theozentrik der theologischen Wissenschaftslehre des HI.

Anton Ziegenaus, SACRA DOCTRINA IN THE DE TRINITA1E 361 The personal encounter between God and human beings implied by the question is in fact the point of departure for the argument: "Because our perfection consists in our union with God, we must have access to the divine to the fullest extent possible, using everything in our power, that our mind might be occupied with contemplation and our reason with the investigation of divine realities. "47 Thomas appeals to divine testimony for his claim by citing Psalm 73. 48 The intellectual pursuit of God, in both contemplative and argumentative modes, is thus enfolded in a more comprehensive quest for human perfection realized in union with God. Moreover, the human yearning for God is positioned within a yet more inclusive theological vision of desire which portrays every creature as naturally drawn to become more and more like God in its own way. 49 In answer, then, to the moral objection that we should humbly refrain from inquiring into divine matters, Thomas responds with the moral imperative to strain after knowledge of the divine on the basis of our natural bent toward the perfection of our human powers-but let human inquiry into divine matters avoid the threefold perils of presumption, rationalism, and overweening pride as it forges ahead to consummate the graced nature's aspiration toward union with God. A theological epistemology appears in the premise that knowing God makes the creature more like him insofar as knowing is a way of being. A theological anthropology appears in the teaching that the human desire to know God represents and Franz Courth, and Philip Schafer (Aschaffenburg: Pattloch, 1985), 678. 47 "cum perfectio hominis consistat in coniunctione ad Deum, oportet quod homo ex omnibus que in ipso sunt quantum possibile est ad diuina annitatur, ut intellectus contemplationi et ratio inquisitioni diuinorum uacet" (In Boet. de Trin., q. 2, a. 1 [93; 37]). It is clear, then, that Thomas is not reducing the Christian faith to a science or the Christian life to a rigid academic pursuit. Its epistemological thrust is rather to be understood as simply one expression of the divine-human encounter, embracing the human desire for a knowledge of God both clear and certain. 48 "Michi adherere Deo bonum est" (In Boet. de Trin., q. 2, a. 1 [93; 37]). Elders notes that the sed contra's citation of 1 Peter 3: 15, which counsels readiness to defend one's faith, was a medieval locus classicusfor justifying the theological enterprise and inquiring into its nature (Faith, 42). 49 "Set quelibet creatura mouetur ad hoc quod Deo assimiletur plus et plus quantum potest, et sic etiam humana mens semper debet moueri ad cognoscendumde Deo plus et plus secundum modum suum" (In Boet. de Trin., q. 2, a. 1, ad 7 39)). 362 LAWRENCE}. DONOHOO expresses the all-embracing desire of the graced human nature for intimate kinship with him. Both together offer a theological propter quid argument ex suppositione finis that justifies the necessity of seeking understanding of the highest mysteries. 50 Supporting this argument from revelation is a citation from Aristotle urging us, "so far as we can, [to] make ourselves immortal, and strain every nerve to live in accord with what is best in us." 51 At first glance, this appeal to philosophical testimony appears surprising since it obscures the distinctively theological turn of the argument. In any case, Aristotle's counsel was intended to animate his readers to aim for suprahuman things, not to defend an inquiry devoutly alert to the sensibilities of a Prime Mover who just might take offense at being the object of mortal inquisitiveness. 52 There is, however, a common logic linking the Christian and Greek teachings: behind Aristotle's assertion lies the doctrine of humankind's affinity with the divine that is both reflected and achieved in the search for divine knowledge. 53 Thomas has raised this insight to the status of its revealed counterpart by marshaling scriptural, theological, and philosophical sources to shape an argument for advancing a quest for knowledge of God that is based in revelation. Indeed, this argument both anticipates and advances an integrated notion of divine science composed of theological and philosophical premises. At the same time, a supplementary instruction safeguards against any confusion concerning the distinctive modes of argumentation by distinguishing theology from philosophy as the discipline that follows upon faith is distinct from the discipline 50 In addition to citing Aristotle to support this argument, Thomas reinterprets benignly certain passages from Job and Hilary which endorse a certain reticence in investigating divine questions. See also In De Qzusis, lect. 1. Propterquid demonstration in theology is discussed in Quodl. 4, q. 9, a. 18; see·also James A. Weisheipl, "The Meaning of Sacra Doctrinain the Summa Theologiael, q. 1," The Thomist 38 (1974): 68-69. 51 "in quantum contingit immortale facere, et omnia facere ad uiuere secundum optimum eorum que in ipso" (Aristotle, Nie. Eth. 10. 7.1177b31-34; quoted in In Boet. de Trin., q. 2, a. 1 [92; 3 7]). See also Aristotle, Metaphys. 12. 7. 52 Such deference is in fact unnecessary toward a self-contemplating Contemplator who is blissfully unaware of any human inquiries made into his existence or nature. 53 Aristotle, Nie.

SACRA DOCTRINA IN THE DE TRINITATE 363 that precedes it. 54 When arguments are employed in matters of faith, it is not a question of reason demonstrating truths of faith, but of applying persuasive analogies from reason to the truths of faith. 55 B) Article 2: The Character of Divine Human Science The foundation of theological reasoning in faith, which protects inquiry into divine matters from the dangers that arise when it is mistaken for merely another human science, is explicated in article 2. Faith as our human entry into a divine knowledge is made possible solely through God's initiative in revealing himself; in him the thinking believer finds the source, motive, exemplar, and illumination for his own quest for divine knowledge. At the same time, it is faith that creates the major obstacle for granting theology scientific status. 56 In any case, the major issue in article 2 is not faith, but the subject, principles, and ways of knowing divine matters on the part of God, the blessed, and wayfarers. Knowledge of this knowing is due to God's freely sharing his knowledge of both his own knowing and creaturely knowing to us creatures who receive this knowledge according to our own mode of reception. Despite its concern to distinguish God's own science from human participation in it, the argument does not articulate a theology of faith. This is in keeping with Thomas's method of assuming principles that he will later justify-a method that will be justified in his teaching on faith. 57 54 "ubi queritur fides, argumenta tolluntur que fidei aduersantur et earn precedere conantur, non ilia que ipsam modo debito sequntur" (In Boet. de Trin., q. 2, a. 1, ad 3 [93-94; 37-38]; see ialso ibid., resp.). See J. Pelikan, The Christian Tradition: A History of the Development of Doctrine, vol. 4, Reformation of Church and Dogma (1300-1700) (Chicago: University of Chicago Press, 1984),! 64. , 55 In de Trin., q. 2, a. 1, ad 5 (94; 39). The metaphysico-theological justification for this is given in q. 2, a. 3 and is treated below. 56 For an examination of the obstacles that sacred doctrine must overcome in order to be recognized as a science, see Chenu's appraisal of Thomas's treatment in the Sentences and how this is surpassed in the De Trinitate and the Summa Theologiae ("La theologie comme science au XIIIe siecle," in Bibliotheque Thomiste, ed. M.-D. Chenu [Paris: J. Vrin, 1957]: 63-92); also Corbin, Le chemin de la theologie, 340-43, 380-86. 57 I treat this issue below in the discussion of In Boet. de Trin., q. 3, a. 1. 364 LAWRENCE]. DONOHOO The responsio of question 2, article 2 is comprised of three parts: (1) the human approach to divine knowledge is distinguished from the "natural" approach (that is, for God and the blessed); (2) two distinct sciences are shown to follow from this distinction: one follows our way of knowing, the other we share in imperfectly; and (3) theological reasoning grounded in faith is interpreted as a participation in God's own knowledge. Thomas begins by stating that the nature of science consists in certain conclusions necessarily following from known truths. Since this also holds for the divine things, there can truly be a science of them. Now the knowledge of divine things can be interpreted in two ways. First, from our standpoint, and then they are knowable to us only through creatures, the knowledge of which we derive from the senses. Second, from the nature of divine realities themselves. In this way they are eminently knowable of themselves, and although we do not know them in their own way, this is how they are known by God and the blessed.58 At this point any human accessibility to this "natural" knowledge other than an awareness of its being enjoyed by God and the blessed is only implied. Our way of knowing the divine things is not natural because the human knower is inadequate to the divine objects known. In the second part of the responsio, however, human participation in the knowledge of God and the blessed even in the present life is acknowledged and described: Accordingly there are two kinds of science concerning the divine. One follows our way of knowing, which uses the principles of sensible things in order to make the divine things known. . . . The other follows the mode of divine realities themselves, so that they are apprehended in themselves [se ipsa capiantur].We cannot perfectly possess this way of knowing in the present life, but there arises here and now in us a certain sharing in, and a likeness to the 58 "Set diuinorum notitia dupliciter potest estimari: uno modo ex parte nostra, et sic nobis cognoscibilia non sunt nisi per res creatas, quarum cognitionem a sensu accipimus; alio modo ex natura ipsorum, et sic ipsa sunt ex se ipsis maxime cognoscibilia, et quamuis secundum modum suum non cognoscantur a nobis, tamen a Deo cognoscuntur et a beatis secundum modum suum" (In Boet. de Trin., q. 2, a. 2 [95; 41)). This argument anticipates the reasoning of SI'h I, q. 1, a. 2; I, q. 1, a. 3; and I, q. 1, a. 3, ad 2. SACRA DOC1RINA IN THE DE TRINITATE 365 divine knowledge, to the extent that through the faith implanted in us we firmly grasp the primary Truth itself for its own sake [propterse ipsam].59 Surprisingly, the point of departure is not the sources of knowledge rooted in reason as distinguished from those rooted in faith, but the difference in epistemological perspective between human knowledge gained through sensible effects and a divine way of knowing taken from the divine realities themselves. Only after the articulation of this sharp distinction is a bridge thrown across the chasm to offer human beings access to the divine perspective. It is faith that enables us wayfarers to participate, if imperfectly, in a kind of knowledge that is not natural for us: God's own intellectual self-possession. Our simple cleaving in faith to the First Truth corresponds analogically to God's immediate self-knowledge, 60 but this can only be a very limited participation in intuitive knowing, as the first part of the responsio has already prepared us to conclude. 61 To the degree that we know in a way other than the discursive mode of thought based on sensible effects, we know in a way that the human intellect cannot adequately describe, as the argument presumes. Hence Thomas's elastic and bare language. It is clear from this obscurity that such an imperfect cleaving to the First Truth is not 59 "Et secundum hoc de diuinis duplex scientia habetur: una secundum modum nostrum, qui sensibilium principia accipit ad notificandum diuina ... alia secundum modum ipsorum diuinorum, ut ipsa diuina secundum se ipsa capiantur, que quidem perfecte in statu uie nobis est impossibilis, sed fit nobis in statu uie quedam illius cognitionis participatio et assimilatio ad cognitionem diuinam, in quantum per fidem nobis infusam inhaeremus ipsi prime ueritati propter se ipsam" (In Boet. de Trin., q. 2, a. 2 [95; 41-42]). See STh I, q. 79, a. 9 for a similar formulation. 60 A later statement seems to contradict this: "Vnde quamuis per reuelationem eleuemur ad aliquid cognoscendum quod alias esset nobis ignotum, non tamen ad hoc quod alio modo cognoscamus nisi per sensibilia" (In Boet. de Trin., q. 6, a. 3 [167; 76]). However, the issue there is the present incapacity of the human intellect to know the essences of immaterial substances. Hence the formulation that "revelation ... is fundamentally circumscribed: it alters what we know but not how we know," while pithy, is too facile (DenisJ. M. Bradley, "Aristotelian Science and the Science of Thomistic Theology," Heythrop Journal 22 [1981]: 168). 61 Later, Thomas will teach that this cleaving through faith rests on the will moving the intellect to the act of belief under the persuasion of grace: "Actus autem fidei est credere ... qui actus est intellectus determinati ad unum ex imperio voluntatis" (STh II-II, q. 4, a. 1). The Ottawa edition (1941) is used for all quotations from the Summa Theologiae. 366 LAWRENCE]. DONOHOO yet a discursive theologizing. Something more is expected from the argument. In the third part of the responsio, Thomas finally arrives at theology in the sense of a discursive human knowing that is based in faith: And as God, by the very fact that he knows himself, knows all other things as well in his way, namely, by simple intuition without any reasoning process, so may we, from the things we accept by faith in our firm grasping of the primary Truth, come to know other things in our way, namely by drawing conclusions from principles. Thus the truths we hold on faith are, as it were, our principles in this science, and the others become, as it were, conclusions. 62 In virtue of our analogical sharing in God's knowledge of all things in himself, we come to divine knowledge in a twofold manner. First, adhering to the primary Truth in faith, we participate in God's self-apprehension in our own way; second, by virtue of this adherence, we come to know other things discursively, just as God's simple intuition of all things follows immediately from his self-knowledge. If the second part of the argument took the human intellect to the extreme limit where it participates in the highest kind of knowledge it can only image but hardly grasp, the third part returns the intellect to its customary horizon. But what are these "other things" that we are to know in our way?63 That there are other things at all is something new in the argument, for up to this point the exclusive concern has been the "divine things." Not only the mode of knowing but also its content returns us a more familiar world. More basically, the reason for this new kind of knowing is simply that there are other beings besides God that are to be known. Theological epistemology thus presupposes creation and 62 "Et sicut Deus ex hoc quod cognoscit se cognoscit alia modo suo, id est simplici intuitu, non discurrendo, ita nos ex his que per fidem capimus prime ueritati adherendo, uenimus in cognitionem aliorum secundum modum nostrum, discurrendo de principiis ad conclusiones, ut sic ipsa que fide tenemus sint nobis quasi principia in hac scientia, et alia sint quasi conclusiones" (In Boet. de Trin., q. 2, a. 2 [95; 42]). 63 The use of aliorum here should be compared with omnium, the last word of STh I, q. 1, a. 3, ad 3, and participatio et assimilatio in the second part of the responsio (see note 59) should be compared with impressio in ibid. Also, the use of sigillatio in In Boet. de Trin., q. 3, a. 1, ad 4 (109; 68-69) should be noted in this context. SACRA DOCTRINA IN THE DE TRINITATE 367 implicitly directs the created knower back to the very ground he is standing on. At this point Thomas makes a significant adjustment. The grasping of the First Truth is now identified with holding firmly to the truths of faith, or (to borrow concepts Thomas sharpens later on) the formal and material objects of faith are here fused. But by identifying the primary adherence to the First Truth with adherence to the principles of faith, Thomas is able to reinterpret the more enigmatic language of human participation in divine self-knowing by the analogy of the act of understanding immediately grasping self-evident first principles. Even knowledge of divine realities that is based in faith can begin to assume a human form. 64 The discursive knowing based on understanding principles is properly the work of reason, but now within a properly theological domain. Insofar as it depends on the principles of faith, this analogy "humanizes" our participation in the divine knowing and brings it within the scope of natural discursive human thinking (secundum modum nostrum discurrendo). Taken together, the two kinds of supernatural knowing-the primary grasp of faith and the theological reasoning following from it-image God's own viewpoint first in terms of object and mode of knowing (first kind), and then in the extension of this knowledge to other beings (second kind). Thus Thomas arrives at a knowledge that participates in divine knowing and assumes a form akin to the human sciences. As a cleaving to the First Truth, faith mediates between God's own knowledge and human reflection on this knowledge. It is itself analogous to both human and divine thinking inasmuch as it participates in the perfect, simple divine intuition while imitating reason's assent to the principles presupposed by all of the other sciences. 64 Since grace observes "the modes of the operations of nature ... the human mind is not illuminated and stilled by forms from another world, but must wrestle with this one, and discover what lies behind and beyond by ranging from point to point: this discursus is present even in the activity of divine faith" ("Appendix 5: SacraDoctrina," 59, in Thomas Gilby, ed., Christian Theology, vol. 1 of Saint Thomas Aquinas: Summa Theologiae, ed. T. Gilby [London: Eyre & Spottiswoode; New York: McGraw-Hill, 1964-81]). 368 LAWRENCE]. DONOHOO The gap between God's knowledge and human participation in it is further bridged by the analogy of subalternated sciences. 65 Just as lower sciences presuppose and accept on faith principles that are self-evident only in higher sciences, so theology presupposes its principles, the articles of faith, by accepting on faith the word of those witnesses revealing what is self-evident only in the "highest science" of God's self-knowledge. The analogical character of this argument is flushed out in the objection one might make that a musician, for instance, could take the trouble of learning mathematics in order to acquire first-hand knowledge of the principles required for musical composition, whereas no one in this world can see for himself the self-evident principles that remain accessible only through faith. 66 What theologians can do, however, is follow the musician's likelier strategy: go to those who know and trust in their knowledge and integrity. They can go yet further, as Thomas does, by advancing reasonable arguments for the necessity and nature of belief. This is possible because scientia divina, like metaphysics, is charged to defend and analogically explain its principles, the articles of faith. 67 It is fitting, then, that Thomas introduces in this teaching on subalternation the concept of revelation, which supports the entire argument, in its relation to faith: "what is self-evident in the knowledge God has of himself is presupposed in our science, and [the articles of belief] are believed on the word of him who reveals them to us through his witnesses." 68 Insofar as sacra doctrina only participates in God's own knowledge through faith as a response to his revelation, it is incumbent on Thomas to investigate this ground of faith and revelation. These subjects are respectively treated in question 3, article 1, and question 5, article 65 "in scientiis subalternatis supponuntur et creduntur aliqua a scientiis superioribus, et ilia non sunt per se nota nisi superioribus scientibus. Et hoc modo se habent articuli fidei, qui sunt principia huius scientie, ad cognitionem diuinam: quia ea que sunt per se nota in scientia quam Deus habet de se ipso, supponuntur in scientia nostra" (In Boet. de Trin., q. 2, a. 2, ad 5 [96; 44)). 66 In Boet. de Trin., q. 2, a. 2, ad 7 (96-97; 44). 67 In Boet. de Trin., q. 2, a. 2, ad 4 (96; 43-44). 68 "ea que sunt per se nota in scientia quam Deus habet de se ipso, supponuntur in scientia nostra, et creduntur ei nobis hec indicanti per suos nuntios" (In Boet. de Trin., q. 2, a. 2, ad 5 [96; 44]).

Once again rational method is employed in the very resolution of an exploration of whether it should be permitted. Obviously this gives the argument an ironic character, but the irony makes a point: to argue against a human science of the revealed mysteries requires the deployment of reason to safeguard the revealed mysteries from reason. Similarly, to forbid philosophical arguments or sources in theology is already to demonstrate the capacity for distinguishing theology from philosophy adequately. Hence the gainsayer as well as the patron of scientific theology must think both theologically and philosophically. Historically, this question responds to the concrete situation of the introduction into thirteenth-century Europe of Aristotelian texts and traditions, and the attendant fear that a scientific theology would profane a canon of teachings personally revealed by God. 71 To grasp the force of this question, we should envision 69 The argument for subalternation in ad 5 prefigures STh I, q. 1, a. 2, where Thomas exploits this analogy to full advantage. Here it is embodied in the fifth response to an objection; there it comprises the pivotal second article of the entire work. A of Thomas's notion of sacred doctrine with that of his predecessors indicates that the originality of his approach is in large part due to this teaching on subalternation. See Elders, Faith, 47. 70 "utrum in scientia fidei, que est de Deo, liceat rationibus philosophicis et actoritatibus uti" (In Boet. de Trin., q. 2, intro. [92; 35]). In fact, q. 2, a. 1 presupposes an affirmative answer to the question this article poses since, as we have seen, Aristotle was cited as a source for supporting the proposition that the divine realities should be investigated. 71 For the impact of the Aristotelian textual inundation of Western medieval thought, see the classic study of Fernand van Steenberghen, Aristotle in the West: The Origins of LAtin Aristotelianism, trans. Leonard Johnston (2d ed.; Louvain: Nauwelaerts, 1970), esp. 59-126, 147-97. For the background to the development of theology as science, see Chenu, "La theologie comme science," 9-108; ibid., Toward Understanding Saint Thomas, 298-310; Congar, History of Theology, 80-91, 95; Elders, Faith, 41; Charles Lohr, "Theologie und/als 370 LAWRENCE]. DONOHOO a science of revealed matters that would not make use of arguments and sources that do not rely on the truths of faith. But if only arguments and sources from the Judaeo-Christian tradition are permitted, one is faced with the difficulty that leading thinkers of this tradition-indeed, the Scriptures themselves-have made abundant use of pagan sources. 72 The real issue, then, is not whether Aristotle, Plato, or other pagan philosophers might be introduced into theology, but whether human learning from any source other than revelation has a role to play in divine science.73 By responding in the affirmative, this argument shows how the conclusions and methods of human inquiry are necessarily constituent of what is now called for the first time sacra doctrina.74 The argument begins with the principle upon which Thomas's entire theology and his concept of divine science are based: "The gifts of grace are so added to nature that they do not destroy it, but perfect it. " 75 This oft-stated principle can be just as often misunderstood, for the relationship of perfect grace to imperfect nature might suggest that nature is somehow merely tolerated, and that, like St. Paul's faith and hope, it will one day pass away. The radical formulation that grace perfects nature, only comprehensible within the horizon of faith, is actually "unnatural" not simply because grace surpasses nature, but because the higher principle here is serving the lower.

For a discussion of this perspective within the context of sacra doctrina, see Thomas C. O'Brien, "'Sacra Doctrina' Revisited: The Context of Medieval Education," TheThomist41(1977):475-99. 74 In Boet. de Trin., q. 2, a. 3, obj. 7 (79; 46) and resp. (99; 48). Noting that scientia divina is the preferred term in the De Trinitate, Maurer adds that for Thomas, "sacred doctrine is the teaching revealed by God in sacred Scripture. More generally, it embraces 'whatever pertains to the Christian religion.' (Summa, prol.)" (Faith, ix). See also his discussion in Etienne Gilson, ed., A History of Philosophy (New York: Random House, 1962), vol. 2, Medieval Philosophy, 164-65. 75 "dona gratiarum hoc modo nature adduntur, quod earn non tollunt set magis perficiunt" (In Boet. de Trin., q. 2, a. 3 [98; 48]). SACRA DOCTRINA IN THE DE TRINITATE 371 nature. 76 As perfective of nature, created grace presupposes, builds on, and even defers to nature by fitting it for what it is incapable of achieving by itself. As an instance of this principle, sacra doctrina presupposes, builds on, and even defers to human reason. 77 Indeed, just as created grace is in the service of nature, so sacra doctrina depends on the enduring presence of natural reason. This becomes clearer if Thomas's foundational axiom is read in the context of the two principles that enunciate the purpose of divine science: the pursuit of divine truth advances our quest for perfection as union with God, and belief is for the sake of understanding what is believed. 78 Beginning with the final cause, one can reason backward from human perfection as God actually intends it to the necessity of faith for setting in motion an intentional union with divine realities beyond our natural grasp. 79 If the human good embraces intellectual union with God, and the basis of this union is faith responding to grace, then faith becomes a necessary instrument in the intellectual perfection of the human person in transit toward the graced end of life with God. 80 Like 76 This is reflected in the teaching that created grace is, as it were, an accident that inheres in the soul (STh I-II, q. 110, a. 2). See also In Boet. de Trin., q. 3, a. 1, ad 2 (108; 68); q. 6, a. 4, ad 5 (171; 84). 77 "Only by a correct demarcation of the scope and territory of both nature and grace could the respective functions of reason and of revelation and the use of each of these in theology be defined" (Pelikan, Growth of MedievalTheology, 286). 78 In Boet. de Trin., q. 2, a. 1 (93; 37); q. 2, a. 2, ad 7 (96-97; 44). 79 STh I, q. 1, a. 1 offers similar reasoning by establishing the need for saCTa doctrina on the basis of the end of human salus, a form of argument that also responds to the Aristotelian teaching on teleological argumentation (see Aristotle, Physics 1.4). This approach reflects both the practical and the theoretical aspects of sacra doctrinainasmuch as human beings are charged with contributing to the attainment of their divinely appointed destiny, which is a contemplative gazing on God. I interpret this article along the lines of interpretation offered by O'Brien, "'Sacra Doctrina' Revisited," 493-99 and J.-H. Nicolas, "Le rapport entre la philosophie et la theologie," Angelicum61 (1984): 5-7. For an alternative interpretation, see Weisheipl, "Sacra Doctrina," 68-69. For short, helpful summaries of classical positions on sacradoctrinaand how they affect contemporary understanding, see Francisco P. Muniz, The WorkofTheology, trans.JohnP. Reid (Washington,D.C.: TheThomistPress, 1958), 10-13, and Weisheipl, "Sacra Doctrina," 57-63. Three attempts to remove contemporary hindrances to understanding Thomas's doctrine are found in Johannes Stohr, "Theologie," 672-73; Brian Davies, "Is Sacra Doctrina Theology?"

DONOHOO the created grace it depends on, faith serves human nature by bringing it to a fulfillment that lies beyond human power. Unlike created grace, it does not perdure, but dissolves into that highest understanding which is the light of glory. In the present state, however, natural reason endures even in the presence of faith, which illustrates the foundational principle of grace perfecting nature in the realm of knowledge: "The gifts of grace are so added to nature that they do not destroy it, but perfect it. So too the light of faith, which is imparted to us as a gift, does not do away with the light of natural reason given to us by God. " 81 The second statement, which places the teaching of question 1, article 1 within the context of divine science, is not related to the first statement by way of analogy, but rather is a precision or instance of it. Faith is a gift of grace, and natural reason is an expression of nature. Three corollaries follow immediately from this principle. First, the truths of faith exceed the natural light of the human intellect. Second, no contradiction can obtain between the findings of reason and the teachings of faith since both derive from God. Third, with contradiction ruled out, an alternative relationship of similarity obtains between an unequal faith and reason: "since what is imperfect bears a resemblance to what is perfect, what we know by natural reason has some likeness to what is taught to us by faith. " 82 The major question concerning the use of philosophy in divine science can now be resolved by applying these corollaries to sacra doctrina: 81 "dona gratiarum hoc modo nature adduntur, quod earn non tollunt set magis perficiunt; uncle et lumen fidei, quod nobis gratis infunditur, non destruit lumen naturalis rationis diuinitus nobis inditum" (In Boet. de Trin., q. 2, a. 3 [98; 48]). It is instructive to compare this formulation with the principle of SI'h I, q. 1, a. 8, ad 2 which clearly links the relation of reason to faith with the relation of grace to nature: "Cum igitur gratia non tollat naturam, sed perficiat, oportet quod naturalis ratio subserviat fidei, sicut et naturalis inclinatio voluntatis obsequitur caritati." 82 "Et quamuis lumen naturale mentis humane sit insufficiens ad manifestationem eorum que manifestantur per fidem, tamen impossibile est quod ea que per fidem traduntur nobis diuinitus, sint contraria his que sunt per naturam nobis indita: oporteret enim alterum esse falsum, et cum utrumque sit nobis a Deo, Deus nobis esset auctor falsitatis, quod est impossibile; set magis, cum in imperfectis inueniatur aliqua imitatio perfectorum, in ipsis que per naturalem rationem cognoscuntur sunt quedam similitudines eorum que per fidem sunt tradita" (In Boet. de Trin., q. 2, a. 3 [98-99; 48]). SACRA DOCIRINA IN THE DE 7RINITA1E 373 Just as sacred doctrine is based on the light of faith, so philosophy is based on the natural light of reason. So it is impossible that the contents of philosophy should be contrary to the contents of faith, but they fall short of them. The former, however, bear certain likenesses to the latter and also contain certain preambles to them, just as nature itself is a preamble to grace. 83 Just as faith is an expression of and response to grace, and natural reason is an expression of and response to nature, so sacra doctrina is an expression of and response to faith, and philosophy is an expression of and response to reason. In short, just as grace perfects nature, so sacra doctrina perfects reason. For this reason, we can expect the three corollaries of the superiority of grace, the noncontradiction between faith and reason, and the relation of perfect-imperfect likeness to apply to sacra doctrina and philosophy. Although presented in a different sequence, the three principles in fact are applied. The principle of noncontradiction is explicitly mentioned and assumed in that the specific yet compatible domains of sacred doctrine and philosophy arise from a common divine source; the principle of perfect-imperfect likeness elucidates the hierarchical nature of their complementarity; and the new formulation of nature as preamble to grace adds a striking restatement of the superiority of grace and the contribution of nature. As applied to sacra doctrina and philosophy, all three corollaries help to illuminate their separate-but-complementary character and define the indispensable role reason plays in the inquiry into divine matters. We can link these corollaries, intimated in yet another sequence, to the three ways that sacra doctrina uses philosophy: demonstrating preambles, proposing analogies, and building defenses: First, in order to demonstrate the preambles of faith, which we must necessarily know in [the act of] faith. Such are the truths about God that are proved by natural reason, for example, that God exists, that he is one, and other truths of this sort about God or creatures proved in philosophy and 83"Sicut autem sacra doctrina fundatur supra lumen fidei, ita philosophia fundatur supra lumen naturale rationis; uncle impossibile est quod ea que sunt philosophie sint contraria his que sunt fidei, set deficiunt ab eis, continent tamen aliquas eorum similitudines et quedam ad ea preambula, sicut natura preambula est ad gratiam" (In Boet. de Trin., q. 2, a. 3 [99; 48]). See Stohr, "Theologie," 674. 374 LAWRENCE J. DONOHOO presupposed by faith. Second, by pointing to the things of faith through certain analogies.... Third, in order to refute assertions contrary to the faith, either by showing them to be false or by showing them to be lacking in necessity.84 Demonstrating the preambles of faith manifests the principle of the superiority of grace, employing analogies engages the principle of perfect-imperfect likeness, and refuting spurious reasoning expresses the principle of noncontradiction. The three principles are now given a "chronological" sequence insofar as philosophy's threefold assignment refers respectively to the acts that precede, accompany, and follow upon sacra doctrina in its precise act of elucidating the mysteries of faith. Philosophy's first task of demonstrating the preambles of faith establishes at the outset that natural reason has an indispensable if secondary role to fulfill in the pursuit of understanding revealed matters. However, this function anticipates sacra doctrina without contradicting either the teaching that divine science depends on faith or the principle that divine science perfects reason. 85 Moreover, the demonstration of the preambles of faith, while "prior" to sacra doctrina and formally lying outside the scope of its principles, is nonetheless caught up in its work. Since divine science participates in God's own intelligibility and "the gifts of grace are added to nature," 86 the preambles of faith simply profess that faith presupposes intelligibility. Understanding what faith proposes precedes faith in the sense that it gives the potential believer cognizance of the terms of belief and so prepares the way for grace. In this way the preambles of faith offer a matrix for the understanding that depends on faith by situating sacra doctrina within the contours of human discourse and preparing it to speak 84"primo ad demonstrandum ea que sunt preambula fidei, que necesse est in fide scire, ut ea que naturalibus rationibus de Deo probantur, ut Deum esse, Deum esse unum, et alia huiusmodi uel de Deo uel de creaturis in philosophia probata, que fides supponit; secundo ad notificandum per aliquas similitudines ea que sunt fidei, sicut Agustinus in libro De Trinitate utitur multis similitudinibus ex doctrinis philosophicis sumptis ad manifestandum trinitatem; tertio ad resistendum his que contra fidem dicuntur, sive ostendendo ea esse falsa, siue ostendendo ea non esse necessaria" (Jn Boet. de Trin., q. 2,. a. 3 [99; 49]). It should be noted that sacra doctrina's dependence on reason to proceed scientifically is not mentioned here, perhaps because this is more properly the concern of logic. 85/n Boet. de Trin., q. 2, a. 2, ad 1 and ad 4 (95-96; 42-44). 86/n Boet. de Trin., q. 2., a. 2 (98; 48). SACRA DOCI'RINA IN THE DE TRINITATE 375 a common language with reason by way of analogy. The preambles as presuppositions of faith thus assume a thematic continuity of subject matter between natural reason and reason illumined by faith that is more fundamental than the discontinuity in their sources of knowledge. Because the actualization of faith requires the intellectual recognition of an appropriate object, faith is perfective of reason only by first presupposing reason just as grace perfects nature only by first presupposing nature. Faith, then, has two sources: it is fundamentally rooted in grace by endowing the believer supernaturally with a share in God's selfunderstanding and perspective, but it is also steeped in nature by enabling the believer to respond to intelligible objects that give content to belief-hence the conclusion that the teachings of philosophy have a secondary role in sacra doctrina. 87 When this teaching on sources is joined to the earlier argument that faith terminates in knowledge of the divine things based on faith, it becomes clear that in unique ways faith both begins and ends in understanding. 88 Philosophy's second function of offering analogies is most intimate to the faith, marvelously exemplified in Augustine's deployment of natural reason to explore the supreme mystery of the Trinity. 89 This function is based on two principles. The first is that grace perfects nature: the analogical structure obtaining between the natural and supernatural orders reflects God's creative fashioning of grace to complement created nature. The second arises from the structure of human divine science: creaturely participation in God's own knowledge enables human beings to take on God's universal intuitive perspective according to a human mode of knowing. Thus the entire argument of the preceding article undergirds Thomas's sparse statement here on the de Trin., q. 2, a. 3, ad 1 (99; 49-50). In Boet. de Trin., q. 2, a. 2 (95; 41-42) (see text quoted in note 59). 89 See note 84 for St. Thomas's reference to Augustine's De Trinitate (In Boet. de Trin., q. 2, a. 3 [99; 49]). "Alors que, pour ce qui est de son premier et de son troisieme role la philosophie demeure extrinseque a la theologie, par sa vocation de fournir des 'similitudes,' elle en devient une partie constituante" (Leo Elders, "Les Rapports entre la Philosophie et la Theologie," Doctor Communis 42 [1989]: 212). • 7 In Boet. 88 376 LAWRENCE]. DONOHOO analogical use of philosophy. 90 Dependent on grace and nature, and situated between divine knowing and natural reason, sacra doctrina mediates God's knowing and human knowing in two distinct moments. First it discovers analogues by inquiry into the created order, and then it applies them to the mysteries of faith. 91 Where can analogues be found? In a supplementary argument building on the concept of subalternated sciences, Thomas enlarges the scope of sacra doctrina by substantially widening the contribution human knowledge makes to it. Whereas the principle of subalternation permits lower sciences to presuppose principles proved in a higher science,92 this argument opens up the possibility of reversing direction by introducing the notion of prior and posterior sciences in the order of study: "posterior parentibus secundum naturam in magis nota et priora naturaliter peruenire" (In Boet. de Trin., q. 3, a. 1 (107; 66]). "Naturalis mentis humane intuitus, pondere corruptibilis corporis aggrauatus, in prime ueritatis luce, ex qua omnia sunt facile cognoscibilia, defigi non potest; uncle oportet ut secundum naturalis cognitionis progressum ratio a posterioribus in priora deueniat, et a creaturis in Deum" (In Boet. de Trin., pro!. [75; 3]). Compare this argument with ibid., q. 1, a. 1, ad 4 (82-83; 18) and q. 1, a. 2 (84-85; 21-23). SACRA DOCTRINA IN THE DE TRINITATE 389 highest things and that our graced nature reaches understanding and perfection only by taking on a perspective that is not our own. 127 Here is where the circle of comprehension enters and justifies the human approach: "But what we first know is known on the strength of what we eventually come to know; so from the very beginning we must have some knowledge of those things which are more knowable in themselves, and this is possible only by faith. " 128 It is natural, not supernatural, faith that is at issue here, as is clear from an immediate application to the order of the philosophical disciplines: metaphysics, the last of the sciences, elucidates more fully the principles incipiently assumed by the inferior sciences which precede it pedagogically. 129 Even natural reason, then, must take certain principles on faith: "every science has presuppositions which the learner must believe." 130 Human knowledge, acquired in this tension between the pedagogical and "natural" hierarchies of the human sciences, is ineluctably caught up in this epistemological circle. Even the foundational principles for knowing anything, as well as those of knowing human knowing, including what may be called this "principle of subsequent justification," are first believed and later demonstrated. By justifying a teaching on epistemological justification already introduced in the prologue, De Trinitate, question 3, article 1 not only demonstrates what was earlier presumed, but completes a · textual imaging of the principle of subsequent justification that spans the text. 127 In Boet. de Trin., q. 2, a. 2 (95; 41-42). 128 "Set quia ex ui illorum, que ultimo cognoscimus sunt nota ilia que primo cognoscimus, oportet etiam a principio aliquam nos habere notitiam de illis que sunt per se magis nota, quod fieri non potest nisi credendo" (In Boet. de Trin., q. 3, a. 1 [107; 66]). 129 For an argument showing that there is no vicious circle involved in the relationship between metaphysics and the other sciences, see In Boet. de Trin., q. 5, a. 1, ad 9 (141; 16-18); see also I Post. Anal., lect. 17; Maurer, Division, 9 n. 21. 130 "Unde quelibet scientia habet suppositiones quibus oportet addiscentem credere" (In Boet. de Trin., q. 3, a. 1 [107; 66]). Decker traces this statement back to Aristotle's De sophisticis elenchi 2.165b3 (Sancti Thomae de Aquino: Expositio Super Librum Boethii de Trinitate, ed. Bruno Decker, Studien und Texte zur Geistesgeschichte des Mittelalters, ed. Josef Koch (Leiden: E. J. Brill, 1965), 111. For a pedagogical correlate (and exception) to this principle, see In Boet. de Trin., q. 6, a. 1, ad 3 (second part) (161-62; 61-62). 390 LAWRENCE}. DONOHOO At this point the analogate from the human sciences is applied to faith: since the goal of human life is perfect happiness, which consists in the full knowledge of divine realities, the direction of human life toward perfect happiness from the very beginning requires faith in the divine, the complete knowledge of which we look forward to in our final state of perfection. 131 A reasonable basis for divine faith, already suggested by the analogy taken from ordinary experience, is now offered on the strength of a second analogy taken from the human sciences. Just as human beings require natural faith in others to attain knowledge of events not available to their own perception, so they require supernatural faith in God to attain knowledge of divine matters not available to their intellect. And just as those sciences which are posterior in nature (that is, from the viewpoint of the most superior intellect) but prior for us presume principles that are only fully justified in the science that is prior in nature and posterior for us, so we begin our quest for full knowledge of divine matters with the faith which can only be justified in the world to come. 132 Knowledge is the framework for faith in both its natural and its supernatural senses, but it can also supplant faith, as in the case of individuals who even in this world "arrive by reasoning at 131 "Cum ergo finis humanae uite sit beatitudo, que consistit in plena cognitione diuinorum, necessarium est ad humanam uitam in beatitudinem dirigendam statim a principio habere fidem diuinorum, que plene cognoscenda expectantur in ultima perfectione humana" (In Boet. de Trin., q. 3, a. 1 [107-8; 66)). This pivotal statement, which so perfectly states the spirit of Thomas's theology as a whole, justifies at least for Thomas the observation of Max Seckler that "Man kann den Geist and das Wesen der mittelalterlichen Theologie vielleicht am besten mit Hilfe der vier Stichworte 'Heil,' 'Wahrheit,' 'Weisheit' and 'Wissenschaft' erfassen" (Im Spannungsfeld von Wissenschaft und Kirche: Theologie als schopferische Auslegung der Wirklichkeit [Freiburg im Breisgau: Herder, 1980], 151). 132 This contrast of the "knowledge of faith" with full knowledge in the vision of God (as opposed to God's own science) indicates that this principle is not simply a restatement of the principle of subalternation (In Boet. de Trin., q. 2, a. 2, ad 5 [96; 44)). Here it concerns principles insufficiently understood but nevertheless applied, as opposed to principles that, known to be proved in a higher science, are employed in complete trust without any intent to clarify them. It is roughly the difference between the use of metaphysical principles in natural philosophy and, to borrow the example of STh I, q. 1, a. 2, the use of mathematical principles in music. SACRA DOCTRINA IN THE DE TRINITATE 391 a full knowledge of some divine things." 133 Faith nonetheless is necessary for some regarding many matters and for all regarding certain matters. A brief survey of Moses Maimonides' five reasons for the necessity of faith confirms this: without faith the depth and subtlety of the divine things would be concealed from human minds, the initial feebleness of the human intellect only reaches perfection at the end of its journey, only very few can attain the comprehensive knowledge of things required for knowledge of God, many are impeded by physical dispositions from perfecting their mind by reasoning, and the many occupations of life prevent many from engaging in prolonged contemplation. 134 For these people faith offers a minimum knowledge, including matters which the few are able to grasp through natural reason. 135 It follows from Thomas's teaching that certain truths of faith are grasped by some through reason that only the theologian is able to identify the true objects of faith, for only he is able to evaluate the actual reach of demonstrative argument and to reserve for faith the domain that lies beyond it. 136 A theology of faith oriented toward its eventual replacement reinforces the position of sacra doctrina within the broad movement from rudimentary faith to the ultimate human happiness of beatific knowledge. We now learn that what we earlier learned about divine science was known on the strength of what we now know in this analysis of faith, which undergirds it. Just as philosophy only gains the perspective of what is prior by nature at the end of its path of discovery and so retrieves its original point of departure as provisional and pedagogical, so sacra doctrina comes to a more complete understanding by elucidating what it earlier assumed and by reinterpreting its earlier selfunderstanding on the ground of this analysis of a philosophical principle theologically applied. This explains the reason for the text's being shaped to reflect the principle only now enunciated 133 "Ad quorum quedam plene cognoscenda possibile est homini peruenire per uiam rationis etiam in statu huius uite" (In Boet. de Trin., q. 3, a. 1 [108; 66]). 134 For the limits of understanding with respect to matters of faith, see In Boet. de Trin., q. 6, a. 1, ad 4 (third part) (163; 65). 135 "ut [homo] saltem per fidem diuina cognoscat" (In Boet. de Trin., q. 3, a. 1 [108; 67]). 136 See In Boet. de Trin., q. 5, a. 4 (153-54; 41-45); SI'h I, q. 1, a. 1, resp. and ad 2. 392 LAWRENCE]. DONOHOO which teaches that what we first know is known on the basis of what we eventually come to know. For the inquiry into natural human knowing in question 1 presupposed sacra doctrina and the explication of sacra doctrina in question 2 presupposed faith, and now those principles are justified which were mediately presupposed in the first question and immediately presupposed in the second one. We thus needed to come this far to understand the principle in the light of its application to sacra doctrina and faith, and to see how the text images its teaching by going back to and behind the beginning in order to justify what necessarily preceded it. The order of knowing and the order of being now merge to explain and teach that the very nature of sacra doctrina is necessarily pedagogical. The analysis of faith thus grounds the earlier teachings which set sacra doctrina on the footing of faith and faith on the footing of God's own science by accounting for the nature and necessity of belief. 137 However, this teaching on faith not only provides a foundation for sacra doctrina, but is itself its achievement since only science possesses the means to develop analogies based on the relationship between divine truths and created realities. Yet the argument for faith, by exploring its very foundation through the principle of subsequent justification, is only the achievement of sacra doctrina insofar as this science is grounded in faith. Only because divine science is based in faith, then, can it explore the basis for faith and its own basis in faith. In other words, only reflective faith can ultimately ground faith because the very essence of faith is such that its transcendence circumscribes its reasonableness and not the other way around. 138 More exactly, faith gives us access to sacra doctrina's reflection on this transcendence out of which faith itself emerges. In the last· fundamental task of divine science to which we now turn, God's self-knowledge will be linked with its human participation in sacra doctrina by revelation, which springs from his selfmanifestation and evokes the response of faith. q. 2, a. 2 (95; 41-42). and reasonableness of Thomas's position is anticipated in the three arguments of the sed contra, which argue that faith is supernatural, necessary, and natural on the strength of the witness of Scripture, Augustine, and Aristotle respectively. 137 In Boet. de Trin., 138 The comprehensiveness SACRA DOCIRINA IN THE DE TRINITATE 393 V. QUESTION 5: SACRA DOCTRINA AND REVELATION The De Trinitate's backward trek from the nature of human knowledge, to sacra doctrina, to natural reason's contribution to sacred doctrine, to its foundation in faith, is always guided by God's own divine science as the paradigm, cause, and end of human knowing. 139 In the programmatic statement elucidating the notion of subalternation, Thomas links God's own science, sacra doctrina as its human counterpart, faith as the ground of theology, and the source of this faith in revelation: "the articles of faith, which are the principles in this science, are related to God's knowledge, because what is self-evident in the knowledge God has of himself is presupposed in our science, and they are believed on the word of him who reveals them to us through his witnesses. " 140 God is then both source of the principles that sacra doctrina literally assumes on faith and guarantor that these principles may be safely believed. Whereas this earlier statement views the principles of faith analogically with respect to God's self-evident knowledge, the later argument for the necessity of faith approaches faith teleologically as incipient instruction to be superseded by full knowledge of divine realities. In this complementary view, the principles of faith remain fully dependent on God's own knowledge, but his knowledge and complete human participation in it are taken as final cause rather than exemplar formal cause. In this way the argument for the necessity of faith amplifies the first half of the programmatic statement on subalternation by exploring more deeply the relationship of faith to sacra doctrina and to God's own science. It also elaborates on the text's rare allusion to revelation by showing how God's providential care for our epistemological needs moves him to grant us the safe and certain knowledge of faith. Yet revelation is introduced here only in terms of faith, that is, on the strength of what is less knowable and posterior by nature. What remains to be shown is This is most clearly articulated in In Boet. de Trin., q. 2, a. 2 (95-97; 41-44). "Et hoc modo se habent articuli fide, qui sunt principia huius scientie, ad cognitionem diuinam: quia ea que sunt per se nota in scientia quam Deus habet de se ipso, supponuntur in scientia nostra, et creduntur ei nobis hec indicanti per suos nuncios" (In Boet. de Trin., q. 2, a. 2, ad 5 [96; 44]). This statement was discussed above with respect to subalternation. 139 140 394 LAWRENCE J. DONOHOO the derivation of God's revelation from divine knowledge as its source according to what is more knowable and prior by nature. In keeping with the textual imaging of the principle of subsequent justification, Thomas finally turns to this basis of faith toward the end of the De Trinitate. Within the context of defining the various speculative sciences and specifically the subject matter of natural theology, question 5, article 4 elucidates the distinction between this science and a knowledge of divine beings that depends on revelation. The point of departure in natural knowledge marks a contrast to the distinctively theological character of questions 2 and 3, but it is against the background of nature that the extraordinary character of revelation-based knowledge most clearly appears. 141 Thomas highlights this difference by inflecting the epistemological character of the argument with a highly personalist approach to revelation in terms of God's act of self-manifestation. There is, however, another way of knowing [divine] beings ... not as their effects manifest them, but as they manifest themselves. The Apostle mentions this way ... "So the things also that are of God no man knows, but the Spirit of God. Now we have received not the spirit of this world, but the Spirit that is of God, that we may understand." And again, "But to us God has revealed them by his Spirit." In this way are treated divine beings as they subsist in themselves and not only inasmuch as they are the principles of things. 142 Here Thomas cites Scripture at length in order to let it speak for itself about speech. A revelatory text reveals the ultimate reason for revelation: "that we may understand." 141 The perspective of reason as the point of departure for the distinction between natural theology and revelation-based theology in In Boet. de Trin., q. 5, a. 4 is indicated by designating the divine being in the plural form (res diuine) which reflects the categories of (Aristotelian) natural theology (153; 43). 142 "Est autem alius cognoscendi huiusmodi res non secundum quod per effectus manifestantur, set secundum quod ipse se ipsas manifestant; et hunc modum ponit Apostol us I Cor. II 'Que sunt Dei nemo nouit nisi Spiritus Dei. Nos autem non spiritum huius mundi accepimus, set Spiritum qui a Deo est, ut sciamus,' et ibidem 'Nobis autem reuelauit Deus per Spiritum suum.' Et per hunc modum tractantur res diuinae secundum quod in se ipsis subsistunt et non solum prout sunt rerum principia" (In Boet. de Trin., q. 5, a. 4 [154; 44]). Since it was already quoted in part in the prologue, this citation from 1 Corinthians 2:11-12, 10 provides an inclusion for the entire commentary. SACRA DOCTRINA IN THE DE TRINITATE 395 Two kinds of theology, then, are to be distinguished: one treats of divine things as the principles of its subject and is identified with metaphysics; the other "investigates divine things for their own sakes as the subject of the science. This is the theology taught in Sacred Scripture." 143 Metaphysics investigates the same divine beings as divine science, but only to account for the causal structure of the visible world. Though honored as dea scientiarum, metaphysics lacks the nobility which arises from a science that is heir to God's own knowledge. For divine science does not simply conclude, but begins with divine beings as its causal principle since it is "non solum de altissimis set ex altissimis est." 144 Because the divine beings have taken the initiative by revealing themselves and inviting a response, they are known not simply from effects that manifest their presence, but from their own revealing word. The principles, in short, are personal. God is approached in this science not primarily to account for lesser beings but above all for his own sake, and not simply by virtue of human inquisitiveness but by virtue of his own self-manifestation. Hence God becomes the subject of a new science, and conversely, a science is established whose subject is personal. This text further sheds light on the arresting title of question 2, "De manifestatione divinae cognitionis." The primary sense of manifestation proposed in question S connotes God's revealing himself, but this expression refers to the manifestation of his mode of knowing. God's revelation is hence the precondition not only for an exclusive knowledge of God, but also for knowing God's own act of knowing and participating in it through faith. 145 The very fact of revelation means that human knowledge of the divine things, as well as all other human knowledge, is ultimately 143 "alia uero que ipsas res diuinas considerat propter se ipsas ut subiectum scientie, et hec est theologia que in sacra Scriptura traditur" (In Boet. de Trin., q. 5, a. 4 [154; 44-45]). The subsequent argument that distinguishes metaphysics from sacred doctrine does so from the viewpoint of philosophy. Mcinerny notes that a sharp distinction between natural theology and sacred doctrine is not to be found in Boethius (Boethius, 130). 144 In Boet. de Trin., q. 2, a. 2, ad 1 (96; 42-43). See ScG II, c. 4. See also O'Brien, Metaphysics, 172-76. 145 "The title 'de manifestatione divinae cognitionis' is perhaps best understood as meaning an examination of the way(s) in which God's knowledge appears or manifests itself, but the words also seem to connote that man must make God's truth manifest" (Elders, Faith, 41). 396 LAWREN CE J. DONOHOO dependent not on human knowledge, but on the divine knowledge of God freely shared with his creatures. Therefore, in a way utterly unavailable to natural reason, sacra doctrina is able to account radically not only for the humanly knowable, but for human knowing by deriving itself from the First Knower as personal subject. For what God manifests to us is himself as knower in the mystery of his self-understanding for the purpose of our sharing in it: "Now we have received ... the Spirit that is of God, that we may understand." A complementary text illumines this ultimate reason for sacra doctrina in its relationship to faith and God's science: "Similarly the proximate starting point of this [divine] science is faith, but its primary source is the divine understanding, in which we put our faith. The purpose of our believing, however, is to arrive at an understanding of what we believe." 146 Hence the very reason for human divine science is to return the human intellect to the divine source in a more perfect imitation. God's knowledge is first revealed to us through his word, then responded to in faith, and finally reflected on in theology. Sacra doctrina in turn is consummated in a deeper knowledge of what faith teaches, and this belief faithfully reflects God's act of revealing, which discloses first himself and then his knowledge of all things. When Thomas's teaching on revelation is linked to that on God's self-understanding as the exemplar of theology, sacra doctrina appears as a divinely willed participation in God's self-understanding through the revelation of his Spirit. Wishing 146 "set finis fidei est nobis ut perueniamus ad intelligendum que credimus" (In Boet. de Trin., q. 2, a. 2, ad 7 [97; 44]). Note that this statement is much stronger than the Augustinian formula of (ides quarens intellectum and Hilary's admonition quoted in q. 2, a. 1: "'Credendo incipe,' scilicet inquire, 'percurre, persiste'" (ibid. [93; 38]). Rather, one needs to look to St. Anselm for an equally vigorous sentiment, which he places on the lips of Boso: "Sicut rectus ordo exigit ut profunda Christianae fidei prius credamus, quam ea praesumamus ratione discutere, ita negligentia mihi videtur, si, postquam confirmati sumus in fide, non studemus quod credimus intelligere" (Cur Deus Homo, 1.1 [ed. Franciscus Schmitt; Munich: Kosel, 1993], 10-12). "Ainsi le schema meme de la structure de la science est le cadre propose pour analyser le developpement de la foi en intellectus fidei: cet epanouissement speculatif, apparement divergent hors de la simplicite contemplative du pur croyant, est, en realite, s'il est bien mene, une remontee de la foi vers la science de Dieu et la premiere etape sur la voie de la vision beatifique, scientia Dei et beatorum" (Chenu, "La theologie comme science," 74). SACRA DOCTRINA IN THE DE 1RINITA1E 397 to make himself personally known and to give us partial access to his way of knowing, God graciously reveals himself such that our faith becomes a grace-infused response designed to flower in a knowledge, based in faith, that imitates the divine knowing: "We are endowed with principles by which we can prepare for that perfect knowledge. " 147 By means of a theology that engages our human intellects with the divine truth, we advance our own goal of perfect happiness as well as the work of God's glorification. Human divine science is now seen as an interest in God for his own sake on the basis of his own word that furthers his own act of self-manifestation. Here we are given a far richer response to the question of whether divine matters should be humanly investigated. 148 We are enjoined to pursue divine truth not simply to advance our own perfection as union with God, but to extend God's own self-manifestation by converting belief into human knowledge. By investigating God's nature and his knowledge, sacra doctrina continues the act of divine self-manifestation in revealing the revealing God. It shows God's knowing. VI. CONCLUSION Having come to the end, we can look back and appreciate the wisdom of the way. Sacra doctrina, resting on God's revelation and shaped by human reason, gives us partial access to God's science and situates human knowing within his comprehensive perspective. Only gradually does human knowing come to a heightened understanding of the divine perspective as archetypal and its own perspective as fundamentally backward. This gradual awareness is reflected in a textual approach whereby divine science unfolds itself in a progressive articulation of its own principles. Hence the logic of inquiring at the outset into the 147 This begins the very last statement of the treatise, which understands faith and the sacra doctrina based on it as preparation for that which lies beyond our nature and attained only through grace: "nobis sunt indita principia quibus nos possimus preparare ad illam cognitionem perfectam substantiarum separatarum, non autem quibus ad earn possimus pertingere: quamuis enim homo naturaliter inclinetur in finem ultimum, non tamen potest naturaliter ilium consequi set solum per gratiam; et hoc est proper eminentiam illius finis" (In Boet. de Trin., q. 6, a. 4, ad 5 [171; 84]). 148 Thus is the teaching of In Boet. de Trin., q. 2, a. 1 confirmed and surpassed. 398 LAWRENCE]. DONOHOO human intellect's nature and limitations, especially respecting the divine things. This inquiry presupposes and then shapes the pedagogical entry into the most universal perspective within which God's self-understanding, the "mixed" knowing of sacra doctrina, and natural knowing are thematized in terms of their likenesses and differences. A textual approach is particularly warranted for uncovering the systematic teaching concerning divine science because this teaching is suspended between God's understanding and human inquiry, and only gradually does it assume the divine perspective without losing its own. The De Trinitate, then, in order to determine the overarching question of what the human intellect can know of God, reflects the mode of human knowing which comes at last to what is first. To this end, it employs from the start its sharpest instrument, sacra doctrina, in both its revelation-dependent and reason-punctuated modes, in order to investigate in turn natural and supernatural knowledge. This investigation requires that sacra doctrina finally come to an adequate self-understanding, and when it does, it reflects God's own self-understanding in keeping with its nature and destiny. Theology's first achievement is to give philosophy a deeper understanding of itself by directing divine science's insights to the nature and boundaries of human knowing. 149 Because it enjoys access to God's own science, theology can offer a more comprehensive understanding of nature than philosophy precisely because the divine perspective is needed to interpret the world as created. In this sense reason depends on sacra doctrina to come to a knowledge of its ultimate causes. Even before it is established, then, sacra doctrina is already at work, illustrating theologically the principle of subsequent justification. Once the nature and limitations of natural knowledge are identified, divine science is free to turn to itself. Its first task is to justify its lofty ambitions. Knowledge of the gift retroactively shapes an awareness of the need for it: the necessity for pursuing a science beyond reason is established through a faith-based awareness of human fulfillment and of the existence of this superior science. Sacra doctrina 149 In Boet. de Trin., q. 1, aa. 1and2 (80-85; 13-24). SACRA DOCTRINA IN THE DE TRINITATE 399 encourages the intellect to pursue the divine truths because the perfection of the human person embraces intellectual union, and the desire for divine knowledge is holy. 150 Prepared for an ambitious career, faith-based reason is immediately assigned the task of investigating its nature as a divine science. Reason helps to discover a knowledge that surpasses it, but only with reason's help can the reflecting faith-shaped mind know what reason is unable to know without the benefit of faith. 151 It is above all faith, however, that gives the human intellect access to God's own knowledge and an awareness of a corresponding relativizing of its own power. Yet faith lends further hope for human participation in a knowledge that transcends human nature. Thus both revelation-based and reason-based knowledge point to each other and acknowledge their mutual, though analogical, dependence mirrored in the shifting perspectives of a text now philosophical, now theological. Reason is explicitly invited to enter into sacra doctrina by contributing to the resolution of the very question of whether it should contribute to divine science. It responds by articulating theology's epistemological principles and by undertaking the three distinctive tasks which precede, accompany, and follow upon sacra doctrina. 152 Above all, natural reason, presenting the notion of analogy, helps divine science to express the analogical relationship of nature to grace and to appreciate the creative hand of One who fashions grace to complement the natures he formed. Then stepping outside of faith in order to recover it, reason contributes compelling reasons for belief, and derivatively, for the divine science which depends on belief and the revelation on which it depends. Turning from divine science to the faith it is based upon, Thomas offers a reasonable basis for faith and thus a more solid foundation for sacra doctrina. 153 The reasons that provide the "reasonableness" of faith, encompassed within a faith-grounded sacra doctrina, are hence the basis and context for 150 In Boet. 151 In Boet. de Trin., q. 2, a. 1, esp. ad 7 (93-94; 37-39). de Trin., q. 2, a. 2 (95-97; 41-44). 152 In Boet. de Trin., q. 2, a. 3 (98-99; 49). 153 In Boet. de Trin., q. 3, a. 1 (106-9; 63-70). 400 LAWRENCE]. DONOHOO the reasons that establish the need for sacra doctrina. 154 Just as created grace ultimately serves nature, so human reflection on the mysteries, having submitted natural knowledge to the service of belief, is now served by a faith that believes in order to understand. 155 Faith, in turn, is grounded in God's revelation, which provides the last critical link back to the overarching divine science of God-a link that is suspended by sheer grace. Now the foundation is complete: just as question 1 's inquiry into reason presupposes sacra doctrina, and question 2's teaching on sacra doctrina requires faith, so now the articulation of faith in question 3 assumes the instruction on revelation in question 5. All of the fundamental tasks of sacra doctrina-offering a "theology of reason"; clarifying the relationship between revelation and reason through arguments based on revelation and shaped by reason; providing a reasonable foundation for faith; and probing the anthropological, epistemological, and theological presuppositions of the complementarity of faith and reason-constitute a "meta-theology" in which divine science reflects on its own act. This expresses and furthers sacra doctrina's urge to replace faith with a knowledge that will only fulfill belief when faith is ultimately left behind. The nobility and immensity of this epistemological enterprise leads to the potential inclusion of the principles of all the sciences within the scope of sacra doctrina, 156 a conclusion reinforced by an overlapping subject matter for human science and divine science. 157 Just as grace serves nature, so revelation serves reason, now in an elevated state as it seeks to imitate more fully the divine knowing. But patience is necessary: Thomas's textual unfolding of divine revelation rooted in God's own self-manifestation images the gradual character of self-disclosure. 158 Since God reveals divine knowing to us through faith and bids us believe that our provisional Similar argumentation is found in STh I, q. 1, a. 1. See Bonnefoy, "La theologie," 433. In Boet. de Trin., q. 2, a. 2, ad 7 (96-97; 44). 156 In Boet. de Trin., q. 2, a. 3, ad 7 (100; 51). 157 In Boet. de Trin., q. 5, a. 4 (153-54; 41-45). 158 In this light Thomas's text once again images his subject matter: since human reflection on human knowledge always remain partial and incomplete, this work, like many other celebrated texts on first things, is left unfinished and fragmentary. 154 155 SACRA DOCTRINA IN THE DE TRINITATE 401 faith-based knowledge will transform into perfect knowledge, human divine science, by coming to understand what it believes, continues the divine act of self-manifestation as a grace-dependent human achievement on the way to consummation. Sacra doctrina, in the end, is the time-bound work of glorification, the understanding of the divine self-manifestation within the manifestation of the divine understanding. 159 159 I am grateful to Norman Fenton, O.P., and Gracemary Snow, O.P., for their helpful suggestions in preparing this study. Its earliest inspiration can be traced to Romanus Cessario, O.P., the late Thomas O'Brien, and the late Thomas Prufer; its more immediate stimulus comes from a seminar conducted by Ulrich Horst, O.P. of the Grabmann Institute at the University of Munich in the summer of 1994. The Thomist 63 (1999): 403-24 THE INDIVIDUAL AS A MODE OF BEING ACCORDING TO THOMAS AQUINAS LAWRENCEDEWAN, 0.P. ru Dominican College of Philosophy and Theology Ottawa, Ontario, Canada CENTLY Timothy Noone 1 and Kevin White 2 have pub- ished papers touching in different ways on individuation n Thomas Aquinas. Both express a degree of approval of the position of Joseph Owens, 3 who holds that for St. Thomas the "global" 4 explanation of individuation is to be found in the doctrine of esse, the act of being. In the present paper I wish to challenge that Owensian view. To do so, I will first criticize the textual claims of Fr. Owens. Second, I will propose a different approach to the issue, less focused on individuation as something 1 Timothy B. Noone, "Individuation in Scotus," American Catholic Philosophical Quarterly 69 (1995): 527-42. 2 Kevin White, "Individuation in Aquinas's Super Boethium De Trinitate, Q. 4," American Catholic Philosophical Quarterly 69 (1995): 543-56. White sees himself as expanding on Owens's line of thinking (545). 3 J. Owens, "Thomas Aquinas (b. ca. 1225; d. 1274)," in Individuation in Scholasticism: The Later Middle Ages and the Counter-Reformation, 1150-1650, ed. Jorge J.E. Gracia (Albany, N.Y.: State University of New York Press, 1994), 173-94. Parenthetical page numbers in the text refer to this essay. 4 This word is from Noone. He tells us: "According to Fr. Owens .•. Aquinas is really a global theorist on the issue of individuation. What he actually holds, in Owens' opinion, is that esse is the ultimate ontological principle of individuation, just as it is the ultimate source of actuality in all created things. If this is so, Thomas escapes immediately from the charge of failing to develop a general account of individuals as such, whether physical or non-physical, which is one of the methodic objections Scotus marshals against [William Peter] Godinus in their debate" (Noone, "Individuation in Scotus," 540). In a review of the Gracia book containing the Owens essay, Noone says: "Owens' interpretation of Thomas' many seemingly disparate descriptions of the principle of individuation is unparalleled in its ability to render Aquinas' account of individuation self-consistent without appealing to awkward genetic hypotheses." He obviously approves of this account. 403 404 LAWRENCE DEWAN, O.P. requiring a cause or principle, and more focused on the individual as a mode of being. I Father Owens presents us with the role of the act of being, and it is one that seems to make things individual: "[Being] is forging all the various elements of the thing into a unit. It is thereby making them what we understand to be an individual" (174). He is basing himself here on a text from Thomas's youthful Commentary on the Sentences of Peter Lombard. We read: "the being of the thing composed out of matter and form, from which [the human mind] obtains knowledge, consists in some composing of form with matter, or of an accident with a subject [consistit in quadam compositione formae ad materiam vel accidentis ad subjectum ]. " 5 Is Thomas saying that the esse itself is a composite? That is what the reply to the second objection, referred to by Owens, does indeed say: "But our intellect, whose knowledge arises from things, which have composite being [esse compositum ], does not apprehend that esse save by composing and dividing. " 6 Owens provides his own reflection on and interpretation of what is being said. Taking first the case of a multiplicity of per accidens accidents (tallness and musical accomplishment) and the person in whom they inhere (certainly a rather per accidens unity), he stresses the "existential" character of the bond uniting them: "they are brought together by real existence in the one person" (174). And he goes on to make the same point as regards the substantial components of the concrete substance. There is no reason in the essence of a person why his or her form (the soul) should be actuating the particular matter of which the body is constituted at the moment. Different matter keeps coming and going with the anabolism and 5 I Sent., d. 38, q. 1, a. 3 (ed. P. Mandonnet [Paris: Letheilleux, 1929], 903), and ad 2 (Mandonnet, 904); quoted in Owens, "Thomas Aquinas," 189 n. 6. While the Latin word "consistit" does not always means "is made out of," as English "consists" would suggest, but can mean "is found with" (cf. STh I-II, q. 2, a. 7: that in which beatitude "consistit" is distinguished from beatitude itself; the former expression refers to that object in which the soul finds beatitude), here it does seem to mean something like the English "consists in." 6 I Sent., d. 38, q. 1, a. 3, ad 2 (Mandonnet, 904). (Owens transl.) IND MD UAL AS A MODE OF BEING 405 catabolism of nutrition, yet the soul remains the same. There is no essential reason, either in the form or the matter, why this particular form should be in this particular matter at the given instant. The reason is existential. The two are united in the existence they are actually enjoying at the time. The existence makes them a unit. (174) Two points should be made here. One has to do with the doctrine of esse found in the texts cited. The other has to do with Owens's conception of the role of esse as related to ens per accidens and ens per se. While Thomas in the cited text does make the esse of composite things a composite, we know that he will subsequently stress the simplicity of esse.7 In commenting on Boethius's De hebdomadibus he says that esse is not a composite: just as esse and quod est differ as to notions, so also they differ really in composites. Which indeed is evident from the foregoing. For it was said above that esse itself neither participates in anything such that its intelligibility [ratio] be constituted out of many, nor does it have anything extrinsic admixed such that there be in it an accidental composition; and therefore esse itself is not composite; therefore, the composite thing is not its own esse.8 And in the Summa contra Gentiles we read: "Nothing is more formal or more simple than esse." 9 7 Noone thinks Owens does well to avoid "awkward genetic hypotheses" (see above, n. 4), but Thomas obviously changes his views on some key issues. 8 Expositio libri Boetii De hebdomadibus 2 (Paris: Cerf; Rome: Commissio Leonina, 1992), lines 204-15 (ed. Calcaterra, no. 32): "sicut esse et quod est differunt secundum intentiones, ita in compositis differunt realiter. Quod quidem manifestum est ex premissis. Dictum est enim supra quod ipsum esse neque participat aliud ut eius ratio constituatur ex multis, neque habet aliquid extrinsecum admixtum ut sit in eo compositio accidentalis; et ideo IPSUM ESSE NON EST COMPOS/TUM; res ergo composita non est suum esse; et ideo dicit quod in omni composito aliud est esse ens et aliud ipsum compositum quod est participando ipsum esse" (small caps added). The Boethius text has, at line 17: "Omni composito aliud est esse, aliud ipsum est." The Leonine editors (Louis J. Bataillon and Carlo A. Grassi) have attempted to italicize this in Thomas's exposition. The "ens" is awkward. Without it, one would think one could underline "et ideo
