In one of the truly great classics of twentieth-century political economy, R. H. Tawney addresses the question of how religion has affected social and economic practices. He does this by a relentless tracking of the influence of religious thought on capitalist economy and ideology since the Middle Ages. In so doing he sheds light on why Christianity continues to exert a unique role in the marketplace. In tough, muscular, richly varied prose, he tells an absorbing and meaningful story.
