As the crisis of capitalism unfolds, the need for alternatives is felt ever more intensely. The struggle between radical movements and the forces of reaction will be merciless. A crucial battlefield, where the outcome of the crisis will in part be decided, is that of theory. Over the last twenty-five years, radical intellectuals across the world have produced important and innovative ideas.

The endeavour to transform the world without falling into the catastrophic traps of the past has been a common element uniting these new approaches. This book - aimed at both the general reader and the specialist - offers the first global cartography of the expanding intellectual field of critical contemporary thought. More than thirty authors and intellectual currents of every continent are presented in a clear and succinct manner. A history of critical thought in the twentieth and twenty-first centuries is also provided, helping situate current thinkers in a broader historical and sociological perspective.
