Gilles Deleuze (1925-1995) was Professor of Philosophy at the University of Paris VIII. He is a key figure in poststructuralism, and one of the most influential philosophers of the twentieth century. In The Fold Deleuze proposes a new and radical way of understanding philosophy and art. Leibniz drew on the art of the baroque period in his invention of the concept of the fold Deleuze develops the concept further to present a new way of practising philosophy based upon the fold as the relationship of difference with itself.
