Gilles Deleuze (French:[il dlz]; 18 January 1925 4 November 1995) was a French philosopher who, from the early 1960s until his death, wrote on philosophy, literature, film, and fine art. His most popular works were the two volumes of Capitalism and Schizophrenia: Anti-Oedipus (1972) and A Thousand Plateaus (1980), both co-written with psychoanalyst Flix Guattari. His metaphysical treatise Difference and Repetition (1968) is considered by many scholars to be his magnum opus. A. W. Moore, citing Bernard Williams's criteria for a great thinker, ranks Deleuze among the "greatest philosophers". His work has influenced a variety of disciplines across philosophy and art, including literary theory, post-structuralism and postmodernism.
