This essay aims at highlighting convergences and divergences between Koselleck’s Historik and Ricoeur’s hermeneutics of historical condition. For this purpose, it will focus on the way both authors critically rework Heidegger’s existential analytics of Dasein, in order to face two main questions, strictly interrelated: on one side, the development of their respective theories of historical time; on the other side, the identification of the determinations of human existence, which make history and historical knowledge possible. In the light of this comparative examination of Koselleck’s and Ricoeur’s reworking of Heidegger’s existential analytics, the final part of the essay will confront their respective conceptions of the relationship between memory and history.
