Heidegger's Platonism challenges Heidegger's 1940 interpretation of Plato as the philosopher who initiated the West's ontological decline into contemporary nihilism. Mark A. Ralkowski argues that, in his earlier lecture course, On the Essence of ...
Truth, in which he appropriates Plato in a positive light, Heidegger discovered the two most important concepts of his later thought, namely the difference between the Being of beings and Being as such, and the 'belonging together' of Being and man in what he eventually calls Ereignis, the 'event of appropriation'. Ralkowski shows that, far from being the grand villain of metaphysics, Plato was in fact the gateway to Heidegger's later period.
