"In one of the 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 so doing, the book offers an incisive analysis of the historical background of present morals and mores in Western culture. "--Jacket.
