This long-awaited book is the first English-language edition of.Simon's first book, Critique de la connaissance morale (1934). Not only does this work clarify the first stages of Simon's intellectual career, it is also a major contribution to moral philosophy. A Critique of Moral Knowledge addresses fundamental issues. How does moral knowledge differ from other practical knowledge? What is the relationship between the moral sense, moral philosophy, and cognition in action? Is politics moral philosophy or simply a neutral technique? This elegant translation will be an important contribution to the conversation on philosophy, politics, religion, and ethics.
