This Dictionary offers points of entry into Derrida's complex and extensive works. From 'aporia' to 'yes', the Dictionary suggests ways into Derrida that show what is at stake in his work. It demonstrates that Derrida is not just about philosophy, but also about politics and pop music. It explains why deconstruction matters, and how Derrida can change the way you think. The A-Z entries are framed by essays on the inherent interdisciplinarity of Derrida's work and on Derrida's relationship to a range of other thinkers.
