When Jean-Luc Nancy first encountered the work of Jacques Derrida in the 1960s, he knew he was hearing something new, a voice genuinely of its time. Thinking with and against each other over the course of their long friendship, the two thinkers reshaped the European intellectual landscape. Nancy’s writings on Derrida, collected in this volume, reflect on the elements of their shared concerns with politics, the arts, religion, the fate of deconstruction, and the future of sense. Rather than studies, commentaries, or interpretations of Derrida’s thought, they are responses to his presence—not exactly a presence to self, but a presence in the world.
