Jean-Francois Lyotard is one of the most important, and complex, French thinkers of the twentieth century. Best known in the English-speaking world for his book The Postmodern Condition, the multi-faceted nature of Lyotard's work has often been obscured by its sometimes problematic association with the postmodern. His life refuses to follow the clear trajectory common to academics in France: it stalls and hesitates, with Lyotard's first 'career' consisting of fifteen years of militant Marxist political engagement. Kiff Bamford traces this circuitous journey, unravelling the thrust of Lyotard's main philosophical arguments, his struggle with thinking and his confrontation with the task of writing and thinking philosophy in a different way.
