Derrida’s philosophy is usually known as a form of critique of metaphysics. This article, however, argues that Derrida’s deconstructions do not only dismantle metaphysics from within, but also remain in themselves thoroughly, and problematically, metaphysical. Its goal is to determine exactly where the metaphysical features of Derrida’s work can be found. The article starts with an analysis of Derrida’s understanding of metaphysics, as well as its deconstruction, by explaining the working of diﬀérance, mainly focusing on its temporality. Further, it will demonstrate how in the temporization or deferral of diﬀérance a metaphysical desire for purity remains eﬀective. In readings of several texts, the mutual interdependence of metaphysics and deconstruction will be sketched. Then the ethical side of deconstruction will be highlighted, both in Derrida’s early work as well as in the slightly diﬀerent elaboration of diﬀérance in the later ethical notions like justice, the gift and the messianic. This results in a distinction of three versions of diﬀérance. Finally, a critical discussion of the metaphysical side of deconstruction will be followed by a comparison of diﬀerent readings of deconstruction and diﬀérance.
