This article aims to highlight the tension between Heidegger’s reading of the Sophist and the interpretive scheme according to which Plato is the founder of Metaphysics conceived as the age of the oblivion of Being. Heidegger works on the «new version of negation» Plato introduced by Plato in Western logic following the «parricide», and he carefully explains the decisive phenomenological consequences of the distinction between “non-being” (which is «blind») and “being- not”, which has an opening and manifestative function. This allows to establish a precise parallelism between the interpretation of me on and the elaboration of the negation which distinguishes between Being and being. It is in the radical “heterogeneity” between them (these two concepts), in which the ontological difference properly consists, that the echo of Heidegger’s confrontation with the Platonic hèteron resonates.
