Dualismes: Doctrines religieuses et traditions philosophiques
Les enjeux du dualisme chez Hans Jonas
This paper summarises the issues of dualism in the philosophy of Hans Jonas. Dualism was a central topic for him to understand gnosticism in late antiquity, and it became also a key concept to understand moral nihilism of the XXth century. Jonas demonstrates that Heidegger’s thought in Sein und Zeit ‑ which enables him to elaborate the heuristic method to shed light on gnostic dualism ‑ was in fact itself based on a dualistic anthropology. On the one hand, Jonas attempted to reply to it with a philosophical biology ; on the other hand, his reply to the cosmological dualism thanks to his speculative and mythical concept of the weak God.
