Abstract

The claim to truth has been common to both positive science and philosophy. But at present there is no consensus concerning what this claim to truth can mean for philosophical inquiry. Can a given philosophical position be regarded as true or false? Is it still possible to say that philosophical inquiry aims at truth at all? I argue that philosophy must be seen as oriented toward the disclosure of truth if it is to retain that critical dimension in which alone constructive disagreement is possible. At the same time, I argue that the concept of truth which regulates philosophical inquiry is not that of the traditional correspondence theory. Rightly interpreted, the correspondence theory describes the meaning of truth for the positive sciences, which are concerned with facts; but it is adequate for an understanding of philosophy, which as a reflective enterprise is concerned with the meaning of facts. The aim of the dissertation, then, is to demonstrate the reflective connection between truth and meaning by exploring the concept of truth as developed in transcendental logic--the enterprise which thematizes the conditions which make knowledge of objects possible. ;In light of this problem, it is possible to see Heidegger's concept of truth in Being and Time as an important contribution to our understanding of the meaning of truth for reflection. Heidegger's theory of truth is often misinterpreted as an attempt to subvert the critical theory of truth as correspondence. However, it is in fact an attempt to situate the concept of propositional truth within a wider notion of truth as the disclosure of meaning as such, a notion which is necessary in order to understand the possibility of propositional truth. ;To show this, the dissertation traces the origin of Heidegger's concept of truth to its source in problems arising from the tradition of transcendental logic. This involves an examination of Heidegger's works prior to Being and Time, as well as a discussion of those philosophers from whom these works derive their inspiration. Most important among them are Emil Lask, whose revision of Kant's doctrine of categories led to a reflective identification of the object as such with meaning; and Edmund Husserl, whose concept of intuition and evidence allows us to see how such "original" meaning is given. But both Lask and Husserl remain tied to a correspondence theory in their attempts to explicate the relation between meaning and truth. Having subscribed to this position in his early works, Heidegger's reflection on the origin of meaning leads finally to the recognition that truth is first of all the historical disclosure of an horizon of meaning or intelligibility, within which alone it is possible to understand how a statement can "correspond" to the entity as it is in itself. ;The dissertation thus aims at establishing two points: that Heidegger's theory of truth is meant to describe a concept of truth adequate to the claims of philosophical reflection; and that this concept of truth must be seen as an answer to specific problems which arise from the theory of truth developed in the tradition of transcendental logic.
