The present article aims to provide an original interpretation of Jan Patočka’s philosophy of history starting from the consideration of the debt it holds with Heidegger’s thought, in particular with the existential analytic of Being and time. Of Heidegger’s analytics, in fact, Patočka grasps and assumes with great radicality and originality the peculiar ‘modal logic’, according to which the existential dimension of closure, inauthenticity and estrangement from oneself is not opposed ‘frontally’ to that of openness, authenticity and nearness to oneself (...) of existence, being rather co-owned by it in the form of a privative modalization. We have therefore aimed to show how such a scheme is the one by which Patočka, in his Heretical Essays, interprets the whole adventure of Western history starting from its ‘emersion’ in ancient Greece. In particular, thanks to such a reconstruction we were able to shed light on the position of the phenomenon of work in Patočka’s philosophy: the Patočkian conception of work, understood as an obstacle par excellence to authentic historical existence, represents not only the true stakes of the comparison of the phenomenological- existential line in which Patočka is inserted with a Marxist theory of alienation; starting from here, moreover, it is potentially a clearer framework of the Patočkian genealogy of Western civilization and its form of subjectivity in relation to the approach of other genealogical philosophies of the last century.
