This article explores the role of the antithesis between Athens and Jerusalem in the work of Karl Marx. Starting from an exploration of Ludwig Feuerbach’s Essence of Christianity, the essay attempts to situate Marx’s ‘On the Jewish Question’ within a longer history of philosophical writings about Judaism. It argues that, like previous writers, Marx depicts the Hellenic world as an implicit Other to Jewish modernity. Marx’s writings about Greece are heir both to the tradition of German philhellenism reaching back to (...) Schiller and to the insights into antiquity arising from the development of historical scholarship. While Marx’s writings have been instrumental in moving away from the Christian worldview, he has also played a contested and ambivalent role in the development of modern anti-Semitism. By exploring the representation of Greeks and Jews in Marx and Feuerbach, this article will trace how the conflict between Athens and Jerusalem played a crucial role in the shift from Christian anti-Judaism to secular anti-Semitism.
