Qu’est-ce qu’un Ansatz? Heidegger et la méthode de la philosophie de la religion

In his Introduction to Phenomenology of Religion Heidegger develops a theoretical model for philosophy of religion, that is more fruitful than most of the models proposed in the rest of his philosophical production. The notion of Ansatz, that I try here to clarify, allows him to think the relationship between phenomenology and Christianity beyond the dyad a priori/a posteriori (pivot of Troeltsch’ philosophy of religion) and on the basis of a concept of time which is completely Christian. The deep theoretical consubstantiality between Ansatz and «hos mé» in the Paulinian sense is living proof of it.
