J.B. Schneewind's remarkable book is the most comprehensive study ever written of the history of moral philosophy. Its aim is to set Kant's still influential ethics in its historical context by showing in detail what the central questions in moral philosophy were for him and how he arrived at his own distinctive ethical views. In its range, analyses, and discussion of the subtle interweaving of religious and political thought with moral philosophy, this is an unprecedented account of the evolution of Kant's ethics.
