What does Bataille seek in the prehistoric cave paintings of Lascaux? How does Dubuffet imagine an art brut, an art unscathed by culture? Why does Jorn populate his paintings with "human animals"? What does Paolozzi see in his monstrous figures assembled from industrial debris? And why does Oldenburg remake everyday products from urban scrap? A study of artistic practices made desperate by a world in crisis, this is an intriguing account of a difficult era in twentieth-century culture, one that has important implications for our own.
