This paper approaches the problem of the relation between Deleuze and Derrida by focusing on their respective readings of Heidegger's interpretation of Nietzsche's eternal return. It argues that the difference between Deleuze and Derrida cannot be measured in terms of their explicit statements about Heidegger, but in terms of how they relate their own readings of Nietzsche to Heidegger's positioning of him as the last metaphysician. The paper focuses on Deleuze's brief analyses of Heidegger in Difference and Repetition and Derrida's numerous references to the eternal return throughout his oeuvre, particularly in the essay Différance. I argue that Deleuze and Derrida articulate two different relations to the simulacrum through the way in which they position their own work in relation to Heidegger's understanding of Nietzsche.
