Now, Heidegger does not believe that the Greek time was any better than modern times, though many still characterize him in this way. Heidegger is not another Winkelmann nostalgic for the age in which "real men" lived; he does not wish he was Greek. Heidegger conducted an intense study of the Greek and early Greek writings in the years before and during the composition of Being and Time in seminars and privately because he realized that the Greeks had a closer understanding of the real ground of ontology than many throughout history. It is not that this understanding allowed them to grasp it better and define it concretely. Indeed, it is often their misunderstandings of Being that Heidegger finds most informative as to what Being is. What is crucial for Heidegger about the Greeks is that they brought Being, the ground of ontology and metaphysics, to words more explicitly than the rest of Western history.
