This article offers an interpretive reconstruction of Heidegger’s first reference to the “inner truth of National Socialism” in the 1934/35 lecture course, Hölderlin’s Hymns “Germania” and “The Rhine”, which has remained unknown due to an editorial error. Focusing on the distinction Heidegger draws between Greek φύσις and natural science, it examines the way Heidegger conceives politics more originally through Hölderlin and the naming force of Nature. It then contextualizes Heidegger’s specific reference to National Socialism in terms of the then contemporary (...) debate between liberalism and the racially determined “new science,” arguing that Heidegger thinks the “inner truth of National Socialism” as a φύσις-event.
