Language and facticity in Heidegger's lecture of Saint Augustine

Language and facticity in Heidegger’s lecture of Saint Augustine. The phenomenological analysis of the Confessions of Saint Augustine gave to Heidegger the opportunity to radicalize the deconstruction of the theoretical path do God and to discover the factical life under the “formal indication” of “the historical”. In Book X of the Confessions Heidegger found an authentic experience of temporality, breaking down with the cosmological concept of time characteristic of Greek philosophy and of metaphysical tradition. The confrontation with such an experience is inscribed in Heidegger’s interpretation of the augustinian concept “cura’‘, that Heidegger will incorporate in Sein und Zeit, as an “existential” accountable for the whole Daseins’s existential structure. So, the phenomenological description of “care”, in the double modality of authenticity or unauthenticity in the Freiburger Vorlesung de 1921 will also lead the heideggerian’s investigation in Sein und Zeit in the direction of the ambiguity of both Daseins’s existence, which moves back and forward, and of Dasein’s language, which swings between Rede und Gerede.
