The development of Ranciere’s philosophical work, from his formative years through the political and methodological break with Louis Althusser and the lessons of May 68, is documented here, as are the confrontations with other thinkers, the controversies and occasional misunderstandings. So too are the unity of his work and the distinctive style of his thinking, despite the frequent disconnect between politics and aesthetics and the subterranean movement between categories and works. Lastly one sees his view of our age, and of our age’s many different and competing realities. What we gain in the end is a rich and multi-layered portrait of a life and a body of thought dedicated to the exercise of philosophy and to the emergence of possible new worlds.
