The twofold character of truth: Heidegger, Davidson, Tugendhat

The concept of truth as aletheia, translated by Kockelmans as non-con- cealment, or as I shall call it unconcealment, is one of the founding concepts in Heidegger’s thinking. It is a concept present in his early thought as well as in his later. Kockelmans himself refers to Walter Biemel’s claim that taken as a whole Heidegger’s thinking has a double focus: being and aletheia,1 and the claim is clearly one with which Kockelmans himself is largely in agreement. It is, however, the same idea of truth that appears here that was famously criticised by Ernst Tugendhat2 in a way that seems eventually to have led Heidegger to abandon the use of ‘truth’ to refer to aletheia.
