Abstract
The purpose of the present investigation is to analyze Heidegger’s critic to Plato’s thought on the question of being with the aim to show that, even though the point of view of such critic varies through the years, the objections remain the same as those who appear in Heidegger’s lecture course about Plato’s Sophist. At the same time, we will try to define the nature of the relationship between both thinkers, that is, if what Plato proposed on the question of being was, given Heidegger’s eminently negative appraisal of Plato’s philosophy, indeed far from what the author of Being and Time stood for or if, on the contrary, Heidegger may had found in Plato a source of inspiration thanks to which he would have developed the fundamental concepts of his own philosophy.
