This essay tries to investigate the possibility to reconstruct the concept of mimesis in Martin Heidegger’s hermeneutical phenomenology in Sein und Zeit. Paul Ricoeur’s interpretation of the concept of mimesis in Aristotle’s Poetics, develops a new temporal understanding of the mimetic activity, which Ricoeur in his work Time and Narrative, claims to have the possibility to overcome the aporias in the phenomenology of time. With this criticism as the background context for the present study, seeks this essay to pick up Ricoeur’s new conception of mimesis, and use that in a comparative philosophical reflection on the basic concepts in Heidegger’s Sein und Zeit. The main thesis in this essay is that Ricoeur’s concept of mimesis can be rethought and reconstructed as a possibility within Heidegger’s thinking.
