Alain Badiou (; French: [alɛ̃ badju] ; born 17 January 1937) is a French philosopher, formerly chair of Philosophy at the École normale supérieure (ENS) and founder of the faculty of Philosophy of the Université de Paris VIII with Gilles Deleuze, Michel Foucault and Jean-François Lyotard. Badiou's work is heavily informed by philosophical applications of mathematics, in particular set theory and category theory. Badiou's "Being and Event" project considers the concepts of being, truth, event and the subject defined by a rejection of linguistic relativism seen as typical of postwar French thought. Unlike his peers, Badiou openly believes in the idea of universalism and truth. His work is notable for his widespread applications of various conceptions of indifference. Badiou has been involved in a number of political organisations, and regularly comments on political events. Badiou argues for a return of communism as a political force. Source: Wikipedia (en)
