Abstract
"Heidegger's way of understanding the originary phenomenon of truth is to "make clear the mode of being of the cognition itself." His starting point is a proposition that is not based on intuition. Someone says with his or her back to the wall: this picture hangs askew. The proposition embodies the claim to have discovered the picture (as a being) in the "how" (the mode) of its being. The proposition displays this "how" of being in language. In the attempt to verify the proposition by sensuous experience, the recognition, according to Heidegger, is directed only to the intended being (the picture) and not to the proposition. It is directed to the being itself (which is to be verified by perception) in its mode of uncoveredness (Entdeckt-heir), i.e., in its showing-itself. Confirmation (Bewährung) means this showing-itself of the being in the same way in which it is intended in the proposition. A true proposition shows the being in its mode of uncoveredness. The phenomenon of "originary truth" does not have the character of correspondence. It is the ground of the concept of truth in the sense of correspondence and propositional truth. By unfolding the meaning of alétheia Heidegger shows us a more originary sense of truth as unconcealment (Unverborgenheit). He wants to show that this concept coincides with the first and originary concept of truth in Greek thinking. In this primary sense only the discovering human Dasein can be "true" while it is Being-discovering (Entdeckend-Sein). On the other hand, beings (Seiendes) that we can find in the world can only "be" in a secondary mode, i.e., as being-discovered (Entdecktsein). They can only make a claim to uncoveredness. Their fundament is the Being-discovering of the human Dasein. The being-true of a discovered being is only possible as being discovered by human Dasein as being-in-the-world. The authentic Being of Dasein, the being-in-the truth, presupposes disclosedness (Erschlossenheit) of the world in states-of-mind (Befindlichkeiten), understanding, and discourse, i.e., the constitution of the being (Seinsverfassung) of human Dasein as thrownness (Geworfenheit) and project (Entwurf)..
