A Heideggerian Critique of Aquinas and a Gilsonian Reply

A HEIDEGGERIAN CRITIQUE OF AQUINAS AND A GILSONIAN REPLY JOHN F. X. KNASAS Center for Thomistic Studies Houston, Texas I IN HIS BOOK, Heidegger and Aquinas: An Essay on Overcoming Metaphysics, John Caputo investigates among other points a claim of Etienne Gilson's followers. Their claim is that Heidegger's charge of an oblivion or forgetfulness of being cannot be pinned on Aquinas.1 Aquinas escapes the charge because he alone in the history of Western philosophy deepens the understanding of being to the level of esse. How could someone who has seized upon the fundamental principle of being be guilty of a forgetfulness of being? Caputo begs to differ. A Heideggerian would find the Gilsonian thesis unimpressive. What Aquinas has done remains too ontical, for it still deals with things and the principles of things. Something else escapes Aquinas's eye, and Caputo variously expresses the Heideggerian dissatisfaction : ... esse for Aquinas means that act by which a thing comes to be " real " rather than " present " in the original Greek sense of shining and appearing, revealing and concealing.... In St. Thomas the original Greek notion of presencing as the shining in which all appearances shine, as a rising up into appearance, into manifestness, has declined into an understanding of Being as "objective presence," the presence of what is mutely there, as a sound in an empty room is thought to be" there" in naive realism and common sense.2 1 John Caputo, Heidegger and Aquinas: An Essay on Overcoming Metaphysics (New York: Fordham University Press, 1982), pp. 100-1, 117-21. 2 Ibid., p. 199. 415 416 JOHN F. X. KNASAS Also: Hence, St. Thomas takes the being, not in its very Being-that is, in its quiet emergence into manifestness-but in its character as something created.3 Then: The metaphysics of actualitas is basically at odds with the meditative savoring of the original sense of Being as presencing.4 Finally: The early Greek experience of Anwesen, of the simple emergence of things into the light, differs fundamentally from St. Thomas's metaphysics of actuality and science of first causes.5 Caputo's conclusion is that one cannot accept Heidegger's criteria of S eindenken and think that Aquinas meets them.6 But a Gilsonian might humbly take Caputo's correction and still feel constrained to note that if the issue is being in the sense of presencing, then another portion of Aquinas's philosophical doctrine becomes relevant, viz., Aquinas's elaboration of the mechanics of cognition. In sum, things are present to us insofar as our form has been informed by their forms. Formal reception of form allows us to become the really other without loss to ourselves . We are then sufficiently actuated to cause the presence of the real as the term of our cognitional activity.7 a Ibid., p. 200. ' Ibid., p. 201. s Ibid., p. 209. 6 Ibid. 7 " ••• knowing beings are distinguished from non-knowing beings in that the latter possess only their own form ; whereas the knowing being is naturally adapted to have also the form of some other thing, for the species of the thing known is in the knower. Hence, it is manifest that the nature of a non-knowing being is more contracted and limited; whereas the nature of a knowing being has a greater amplitude and extension. That is why the Philosopher says that the soul is in a sense all things." Thomas Aquinas, ST I, 14, 2c, ed.

Catan (Albany: State University of New York Press, 1981), pp. 81-98. A GILSONIAN REPLY TO HEIDEGGER 417 Once more, however, I believe that we have philosophers speaking past each other. For Heidegger believes that presencing requires an understanding of being as an a priori condition. Many texts to this effect exist. One of the most striking is from Heidegger's The Basic Problems of Phenomenology (1927). I would like to quote it at length. In...
