The τέλειον is a determination of the ἀγαθóν, and so has, as with ἀρετή—which we will later also come to know as a fundamental determination of the being of life—a peculiar relation to being-completed. In having something at one’s disposal, having a definite possibility of one’s being at one’s disposal, this being is already held in its end, and I have my genuine being-possibility already in hand as my possession. Τελείωσις [MF   4 16, 1021 b 20sq]: this peculiar phenomenon of ἔχειν τὸ τέλος is what Aristotle comes to speak of explicitly. [Heidegger  , GA18:84]
