"Masterfully integrating Europe-wide debates in science, philosophy, technology, economics, and social policy, Rabinbach has provided us with a profoundly original understanding of the productivist obsessions from which we are still painfully freeing ourselves. . . . A splendid example of the mutual enrichment of intellectual and social history. It goes well beyond its central concern with the 'science of work' to illuminate everything it discusses, from Marxism to the social uses of photography, from cultural decadence to the impact of the First World War."--Martin Jay, University of California, Berkeley
