Essence of Truth [PDF ebook] 
On Plato’s Cave Allegory and Theaetetus

The Essence of Truth is an examination of the most fundamental theme in Heidegger’s philosophy: the difference between truth as ‘the unhiddenness of beings’ and truth as ‘the correctness of propositions’. Based on a course of lectures delivered at the University of Freiburg in 1932, the book presents Heidegger’s original analysis of Plato’s philosophy and represents an important discussion of a fundamental subject of philosophy through the ages.
