The course aims to analyze the interpretation of ancient Greek religiosity provided in his writings by Simone Weil (1909-1943), which is of particular interest, constituting a relevant exception in the contemporary philosophy of religion. For the great French philosopher and mystic, unlike what generally happens starting from Humanism, between greek religion and thought (up to Plato) and Christianity there is no break and, indeed, there is a direct filiation of early Christianity from archaic Greekness. This original vision (which is polar opposite to that of Nietzsche, also from the, so to say, theological-political profile, revealing the unmistakable stigma of the Epoch) entails a devaluation of the usual relationship established by theology between Judaism and Christianity, leading to a fascinating and problematic genealogy of the origins of western civilization, whose post-Platonic and post-Constantinian drift would be at the origin of the catastrophe experienced by Europe in the twentieth century, with the predominance of force, war and class exploitation, on that love which, for Simone Weil, proceeds directly from the Platonic "divine mania" to become incarnate definitively in Christ.
