WHAT HAPPENED TO PHILOSOPHY BETWEEN AQUINAS AND DESCARTES? JoHN DEELY Loras College Dubuque, Iowa INTRODUCTION a. Pondering the Imponderable HE NEO-THOMISTIC revival launched by Leo XIII eems to have run its main course with an almost exclusive ook at the works of Thomas himself without taking much into serious consideration the work of his Latin commentators. At this moment, we find that a book translated from the work of the last of the Latin commentators, the Tractatus de Signis of John Poinsot, while receiving no significant treatment within the Catholic intellectual world,1 is seriously discussed within the international intellectual movement that has grown up in the last quarter century around the study of signs and reviewed in such mass media as the Times of New York, Los Angeles, and London. 2 Such a situation participates in improbability. My own view is that The Semiotic of John Poinsot (as the work in question is subtitled in its contemporary edition) is a harbinger of what 1 For details, see footnote 2 of the article by James Bernard Murphy, "Language, Communication, and Representation in the Semiotic of John Poinsot," in this issue. 2 Thomas A. Sebeok, " A Signifying Man," feature review of Tractatus de Signis in The New York Times Book Review for Easter Sunday, 30 March 1986, pp. 14-15, also in German translation by Jeff Bernard in Semiotische Berichte Jg. 11 2/1987: 234-239, with translator's "Anmerkung" p. 240; Richard J. Morris, The Book Review of The Los Angeles Times, Sunday, 11 May 1986, p. 8; and Desmond Paul Henry, "The Way to Awareness," The Times Literary Supplement no. 4,413 (October 30-November 5, 1987), p. 1201. 543 544 JOHN DEELY the postmodern development may prove to be. Postmodernism, in my view, is not to be, as initially appears, a kind of literary/ sophistic attempt to eviscerate rational discourse in philosophy through a forced control of signifiers made rather to dismantle (under the mantra of " deconstruction ") than to constitute some text taken precisely as severed from any vestige of authorial intention. Postmodernism in the long run will be seen rather as the term inevitably employed through juxtaposition with the internal dimensions of the classical modern paradigm so as to establish thereby a philosophical sense of a change of age and temper of thought defined historically but able to link contemporary requirements of speculative understanding with late Latin themes omitted from the repertoire of analytic tools developed by modernity. 3 b. Naming the names Several names here bear explaining, not the least of which is "semiotic." Suffice it to say that this is the name coined by John Locke in 1690 to designate the field of investigation that would result from thematic inquiry into the role of signs in human affairs wherever there is a question of experience or knowledge. This study, or "doctrine of signs," as Locke also called it, turns out to be extensive, since it embraces the whole of human knowledge from its origins in sense to its most refined intellectual forays in whatever field, and the realms of social interaction and cultural development as well.4 Sacramental theology has its foundations in the sign, and experimental study depends on the interpretation of signs throughout its ambit. Whether we look to communication as between God and human beings, between human beings among themselves, between human beings with 3 This is the argument of my work, New Beginnings: Early Modern Philosophy and Postmodern Thought (Toronto, Canada: University of Toronto Press, 1994). 4 " Sommaire: c'est dans la tradition de Peirce, Locke, et Jean de SaintThomas que la logique peut devenir une semiotique qui absorberait l'epistemologie et meme la philosophie de la nature" (Eleuthere Winance, Revue Thomiste, LXXX[juillet-aout 1983], 514-516. BETWEEN AQUINAS AND DESCARTES 545 other species, or between human beings and the physical world, we find ourselves caught up in a web of sign relations. It is hardly without interest to discover that the first thinker who was able to systematize the unity of the object of inquiry the action of signs provides was a thinker from the end of the Latin Age who also was a principal commentator on and developer of the thought of Thomas Aquinas. For centuries the Morning Star and the Evening Star were not known to be but a single planetary entity seen in two different contexts. So for those few over the last three and a half centuries who have known of or studied at all the thought of the Latin author called Joannes a Sancto Thoma, he has always appeared to be an Evening Star of Latin Scholasticism and even of the Latin Age itself which began with Augustine (the first thinker to go on record with the view that the notion of sign has the capacity to unite in a single object of inquiry the otherwise disparate domains of nature and culture). It comes as something of a shock and sometimes-to judge by the resistance of some to the discovery-a rude awakening to discover that this Evening Star of scholasticism is at the same time a Morning Star of the postmodern age. Such is the identity of Joannes a Sancto Thoma with John Poinsot. He was author in 1632 of the first systematic treatise to establish the foundations of semiotic inquiry as a unified subject matter, proclaiming on his deathbed in June of 1644 that he had taught and written nothing over the last thirty years of his life that did not seem to him consonant with truth and conformed to the thought of Aquinas. 5 5 The Solesmes editors of Poinsot's Cursus Theologicus give this description of Poinsot's deathbed in their Introduction to the first volume (1931: xii, U 39) : " Generali praemunitus confessione, religionis habitus indutus, sacram Eucharistiam humi genuflexus adorare voluit atque in conspectu Dei sui magna voce protestatus 'numquam triginta annorum spatio aut scripsisse aut docuisse quod veritati consonum, atque Angelico Doctori conforme non judicaret . . . numquam regi quidquam consuluisse quod non in majus Dei obsequium, reipublicae commodum et Principio beneficium credidisset,' laetus in pace Domini exspiravit, die 17 junii 1644, quinquagesimo quinto aetatis anno nondum plene exacto." 546 JOHN DEELY A third name that bears explaining beside that of semiotic and the name of Poinsot himself is "postmodemism." Like Protestantism, postmodernity is a term and idea which has its meaning from an opposition. In this case the opposition is to the classical modern development of philosophy as it occurred between Descartes and Kant and dominated philosophy even into the early and middle years of the twentieth century. This development isolated reason not only from its contact with the physical being of nature but also from the subjective resources of reason in the affective life and social being of the knower. Both ruptures are rejected by thinkers called accordingly "postmodern." The work in semiotic of John Poinsot best establishes the framework in which it becomes possible to heal such ruptures and to attain a philosophical synthesis beyond the modern opposition of idealism to realism. Let this overview suffice to introduce this first of the melange of three essays offered in this issue of The Thomist in honor of an author dead now exactly three-hundred and fifty years. Each of the essays looks to a different aspect of the thought of Poinsot, and together they will barely scratch the surface of the treasures his writings offer to the postmodern age. I devote the principal thrust of my essay to establishing Poinsot's value as a point of recuperation of the lost centuries closing the Latin Age in their bearing on the contemporary situation in philosophy. 1. Posing the Problem The standard answer to the question of what happened in philosophy between Aquinas and Descartes is " Not much, apart from Occam." Even the recent recrudescense of interest in the specifically early phase of the modern period has so far done little to change this standard answer, because the principal scholars investigating the period look almost exclusively to the classical modern sources and the nascent classical mainstream development those sources gave rise to as eventually culminating in the work of Immanuel Kant. BETWEEN AQUINAS AND DESCARTES 547 This train of investigation is unfortunate, because the standard story of early modern philosophy is as much a record of prejudices and narrow preoccupations (especially methodological ones) as it is a record of a properly philosophical development. Until the classical modern sources are viewed in a new light, it is not likely they will contribute much to the telling of a different story. A different story about the early modern development is not only possible but demanded as soon as we take the trouble to view the situation of early modern philosophy less in terms of its classical mainstream development than in terms of the actual relations obtaining in the age of Descartes between the choices which led to the mainstream modern development and the wider possibilities for choice which the speculative Latin context of that period provided. But these possibilities were destined to fall between the cracks of history until Charles Peirce, inspired by Locke's anomalous conclusion to his Essay concerning Humane Understanding (otherwise launching modern empiricism) gave them life again in our time as an inevitable trajectory along which postmodern thought must rise and eventually achieve definition of itself in positive terms. The history of early modern philosophy can be recounted in ways much more interesting and relevant to postmodern developments than the standard studies narrowly focussed on Descartes and Leibniz, or Locke and Hume, would have us believe. But we have to be willing to abandon the established academic pattern of approaching the early modern period only in order to study over again, in ever greater detail, the classical modern sources as giving rise to the mainstream modern development with its culmination in the Kantian synthesis. For to see a live alternative to this standard approach, it is necessary to look in the other direction, so to speak, and to investigate not the classical modern sources in relation to one another, but the horizon itself of Latinity against which the classical modern authors set themselves. Once we consider the ideas of Descartes and Locke in relation to the then-current Latin speculations as developments of the fifteenth and sixteenth centuries, the Latin horizon proves 548 JOHN DEELY to be a context wider and more subtle than either the father of rationalism or the father of empiricism actually drew upon in fixing the direction for the future of philosophy in its classical modern guise. Not only does the late Latin milieu provide a wider context of speculative possibility than either Descartes, Locke, or their classical modern successors realized, but, as we can now see regarding it from the advantage of a nascent postmodernism, the Latin milieu provides a richer context as well, one which arguably adumbrates the full requirements of a philosophy which has experience integrally understood for its center of gravity. 6 The opportunity a backward glance from the early modern period affords us today, it needs to be said, is by no means one easily exploited. Approached from its Latin side rather than from the side of its emergence out of Latin into the national language traditions of classical modern thought, early modern philosophy becomes a dismaying maze of the greatest difficulty to navigate. Without some sort of compass and guide providing an initial orientation, the whole landscape dissolves into a morass of material repetitions of terms and multiplication of abstruse distinctions leaving the visitor practically without a clue beyond the engrained modern prejudices toward the later Latins which every contemporary has imbibed with the air we breath. Needless to say, the orientation more or less unconsciously provided by such prejudices is not particularly helpful if it is to be a question of attaining a new understanding of the possibilities inherent in the late Latin matrix of early modern philosophy (whether retrospectively or prospectively considered), and eventually seeing those possibilities with rinsed eyes in their bearing on the future of thought and, hence, postmodernism. A familiar guide, one who orients us in terms of the classical modern development as it actually came about, is perforce the 6 See my essay on " Philosophy and Experience," American Catholic Philosophical Quarterly LXVI.3 (Summer, 1992), 299-319. For a more systematic and purely theoretical or speculative discussion, see The Human Use of Signs (Lanham, MD: Rowman & Littlefield, 1994). BETWEEN AQUINAS AND DESCARTES 549 least useful one. What is called for rather is a guide or, indeed, any number of guides, unfamiliar in terms of the actual modern development after Descartes, but intimately familiar with the Latin development up to the time of Descartes which provided the surrounding context of Descartes's work. That there could be some such " neglected figure " or " figures " capable of orienting us in terms of the intrinsic possibilities of the Latin development and proving that those possibilities are not what Descartes and the mainstream moderns have heretofore led us to believe they were is clearly a research hypothesis of some heuristic value, and insofar worth investigating. For even though, as far as the history of early modern philosophy goes, it is impossible to study it while leaving out the standard figures, it is equally impossible to enlarge the early modern context through the Latin sources if we regard those sources solely from the standpoint to which the standard figures have accustomed us. We need non-standard figures as guides, ones who knew the whole early modern Latin context, and therefore who knew the Latin development better than Descartes himself. In particular, with a view to the postmodern development, we need a guide who is able to show within the late Latin context an orientation toward a notion within experience of being understood as prior to the categories and to any division of being into what is mind-independent and mind-dependent. Recent investigations have revealed several such figures, 7 but my own research has come to rely particularly on the early 17th century synthesis of late Latin thought made by Joao Poinsot ( 1589-1644), a man born seven years ear lier than Descartes and deceased six years earlier. A man in his own right squarely of the early modern period, familiar with its Zeitgeist and subject to its demands, Poinsot was yet oriented to the Latin past rather 7 See in particular the studies of the Dominican philosopher Mauricio Beuchot, Significado y Disrnrso.
