The works of French philosopher Alain Badiou range from novels, poems, 'romanopéras' and popular political treatises to elaborate philosophical arguments engaging with mathematical theory. Badiou suggests that 'philosophy is always a biography of the philosopher', and throughout all of his writing there is a staunch commitment to emancipatory politics and a radical yet faithful subjectivity.His famous, or infamous, philosophy of emancipation is firmly grounded in his fidelity to the universal idea of a collective life. Introducing Alain Badiou is an elegantly written and crisply illustrated guide to an essential contemporary thinker.
