We designate as existence (Existenz) the ultimate basic possibility in which being-there genuinely is. Existence in the radical sense is, for the Greeks, precisely that way of being-in-the-world, whiling one’s time in it, on the basis of which the ὁρισμóς, as speaking with the world, is motivated. Existence, the radical basic possibility of being-there, is, for the Greeks, βίος θεωρητικóς: the life whiled away in pure contemplation. [Heidegger  , GA18:44]
