In a little more than a decade, economist Michael A. Lebowitz has written several major works about the transition from socialism to capitalism: Beyond Capital (winner of the Deutscher Prize), Build It Now, The Socialist Alternative, and The Contradictions of 'Real Socialism.' Here, he develops and deepens the analysis contained in those pathbreaking works by tracing major issues in socialist thought from the nineteenth century through the twenty-first. Lebowitz explores the obvious but almost universally ignored fact that as human beings work together to produce society's goods and services, we also 'produce' something else: namely, ourselves. Human beings are shaped by circumstances, and any vision of socialism that ignores this fact is bound to fail, or, at best, reproduce the alienation of labor that is endemic to capitalism. But how can people transform their circumstances in a way that allows them to re-organize roduction and, at the same time, fulfil their human potential?
