Abstract

This slender volume attempts to determine the role of logic in Heidegger’s thought and its incompatibility with logic as others understand it, so as to show that Heidegger’s overcoming of logic entails an overturn of philosophy as conceived since Plato. Fay carries this out in six steps: 1) Heidegger’s critique of logic is motivated by metaphysics’ forgetfulness of Being and by the need for a fundamental ontology of alëtheia; 2) the primacy of the preconceptual, prelogical grasp of Being shows that not logic but "the command of Being," grasped "by a thankful gesture of acceptance", rules thought; 3) discussion of "Nothing" in Wegmarken, Carnap’s attacks thereupon, and Heidegger’s counterclaims; 4) discussion of the devolution from truth as the bond of physis-alëtheia-logos to truth as correspondence; 5) a Heideggerian view of the development of symbolic logic and its relation to technicity; 6) the overcoming of technicity in Heidegger’s meditation on language. Professor Fay concludes that Heidegger’s reflection on logos is incompatible with logic as ordinarily understood but that the attempt to overcome traditional logic delivers Heidegger’s thought not to irrationalism but to the original sense of logos.
