AQUINAS AND HEIDEGGER: THE QUESTION OF BIDLOSOPHICAL THEOLOGY VINCENT GUAGLIARDO, O.P. Dominican School of Philosophy and Theology Graduate Theological Union Berkeley, Oalifornia I N IDS BOOK, Hediegger and Aquinas: An Essay on Overcoming Metaphysics, John D. Caputo recommends a " deconstruction" of Aquinas' philosophical theology in order to let .the true ·element orf his thought, mysticism, come to the fore. Caputo argues persuasively that Aquinas' thought, expressed ·as .it is in the garh of metaphysics, cannot escape Heidegger':s critique of met:aiphysfos as "onto-theo-logioal ". Aquinas, no more thoo .any other thinker of the West, has succeeded mavoiding this iorgorttenness. Those Thomi:sts who have tried to argue that Aquinas .is an exception rto this critique , Caputo oontends, have not succeeded in presenting their case. The verdict o.f Heidegger stainds. The on:ly reoourrse left is thart of deconstruction, which Capurto presents ais gaining mther than losing the true Aquinas precisely because deconstruction .allows us to move from the said (the metaphysical dimension) fo rbhe uil!said (the mystical dimension) of Aquinas' thought. The uns1aiid is the kernel, the center a;ro:und which whatever Aquinas says moves. It is the true dimension which his thinking il'eally seeks: union with God, in wh~ch both the union and God 1are themselves rineff1a;ble.1 There is, however, .a disturbing problem which I find wti:th Capui;o's conclusion. This problem does not have to do with his oonte!lltion that the true kernel of St. Thomas' thought !is mysticail. Ra.ther, the problem concerns what is being disen1 See John D. Caputo, Heidegger and Aquinas: An }j}ssay on Overcoming Metaphysics (N.Y.: Fordham University Press, 1982), pp. 211 & 247-8. 407 408 VINCENT GUAGLIARDO; O.P. gaged and put out of play tin the deconstrrucrb.ion, namely: philosophical thoology.2 What are the iimplicatfons of such a movie? Are they desirable for theology? Ought we and oan we, 1a;s Caputo suggests, disengage ,and leave behind St. Thomas' philosophical theology because metaphysical without there being any true loss? Might we be facing a;n impoverishment of another kind: in a moI"e " radical " seeking of the dii.vine might we not be losing something m'a foI"getfulness of ourselves as, .after 1 all, omy human? ls not this something precisely the ,realm of the humanitas of the homo huma,nus, which Heidegger 's thinking seeks Ito point out and draw us closer to, where humanitas refers to our necessary trelation to Heing, from whlch relation we as humans cannot detach ourselves so long as we are " auf die Erde " ? 3 The ~oblematic In beginning our inquiry I would like to distinguish three different regions of human engagement in which the over1appii .ng of one onto the other ii.s not .always easy to discern: philosophy, phl1osopihioal theology and mysticism.. I want to say "iphilosophical theology " and not simply " theology " because I think that it ii.s not possible to thoologize without 1 at the same time also philosophiizing. I 1think St. Tihomas thought this as well. 'l\hat is why his theology was always philosophioa ;l, 1in dialogue wiith :the philosophers: Aristotle, the Platonists, Ma~monides and the Ail1abs. In saying this, however, I do not mean to ,say that philosophy 1and theology 1 are 1 the same. Now the altemativce which Caputo would ha,ve us embrace, because presumably not onto-theo-logioal, is that of a "reli2 See Caputo, op. cit., 11 & 283. a" Die Wahrheit des Seins denken, heisst zugleich die humaniitas des homo humanus denken " (" Brief iiber den Humanismus," in W egmarken (Frankfurt am Main: Vittorio Klostermann, 1978), p. 349). This Latin expression is a.lso used by St. Thomas in De ente et essentia, III, to designate the formal principle (rationality) by which. the whole (an individual human being) becomes a whole.
