We are now asking about the determinations of the ἀγαθóν as such. We know that ἀγαθóν is τέλος. Therefore, what is presumably asked about is the character of being-an-end, of finitude (Endlichkeit), the τελειóτης, insofar as the ἀγαθóν is τέλειον, insofar as it constitutes being-completed. The ultimate question is: which way of being of human beings is it that suffices for the τέλειον ἀκρóτατον? Ἀγαθóν is not an objective thing buzzing around, but instead is a how of being-there itself. [Heidegger  , GA18:69]
