Abstract

This is a philosophical and historical study of the German Jewish philosopher Franz Rosenzweig. It is argued that Rosenzweig's thought is best understood within the horizon of German interwar philosophy alongside the thought of his contemporary, Martin Heidegger. The two philosophers are presented as offering divergent articulations of a larger, shared project; and they are understood as participants within a philosophical movement that the author calls "philosophical expressionism" after the various other expressionist movements of the 1920s. The affinity between Rosenzweig and Heidegger is traced from Rosenzweig's earliest study of Hegel's statist theory through his engagement with Hermann Cohen's neo-Kantianism as well as the Bible-translation. The dissertation culminates in a detailed reconstruction of the famous Davos disputation between Ernst Cassirer and Martin Heidegger, which Rosenzweig interpreted as a symbolic encounter between the older, idealist mode of philosophy and his own "new thinking" . It is argued that the affinities between Heidegger and Rosenzweig are far deeper than has been formerly acknowledged
