In this paper we examine the key phenomena associated with the notion of kairos in Heidegger‘s pre-Being and Time writings and show that they all fall short of the methodological constraints and conceptual requirements placed on authentic presence in 1927. Though Heidegger‘s early studies of Aristotle and the New-Testament are broadly suggestive of the notion of temporality that is presented in his systematic treatise, none of those earlier texts carry the differentiations within which the Augenblick of Being and Time is situated. We thus claim that the ekstasis of authentic presence is neither reducible to an eschatological nor to a phronological kairos.
