Since its original publication in 1985, this hugely influential book has been at the centre of much debate. The arguments and controversies it has aroused are, furthermore, far from abating: the disintegration of the Soviet bloc, the emergence of new social and political identities linked to the transformation of late capitalism, and the crisis of a left-wing project whose essentialist underpinnings have increasingly come under fire have, if anything, made more relevant than ever the theoretical perspective that the book proposes. Moreover the political project of ‘radical and plural democracy’ that it advocates provides a much-needed antidote to the attempts to formulate a Third Way capable of overcoming the classical opposition between Left and Right.
