Gilles Deleuze and Jacques Derrida have each made significant contributions to philosophies of difference and yet few have tackled the difficult task of studying the connection between the two.

What emerges is a fascinating study of the similarities and differences between the two philosophers and in particular the ethical and political threads underlying their connection.
