Naturalism and Realism in Kant's Ethics

In this comprehensive assessment of Kant's metaethics, Frederick Rauscher shows that Kant is a moral idealist rather than a moral realist and argues that Kant's ethics does not require metaphysical commitments that go beyond nature. Rauscher frames the argument in the context of Kant's non-naturalistic philosophical method and the character of practical reason as action-oriented. Reason operates entirely within nature, and apparently non-natural claims - God, free choice, and value - are shown to be heuristic and to reflect reason's ordering of nature. The book shows how Kant hesitates between a transcendental moral idealism with an empirical moral realism and a complete moral idealism. Examining every aspect of Kant's ethics, from the categorical imperative to freedom and value, this volume argues that Kant's focus on human moral agency explains morality as a part of nature. It will appeal to academic researchers and advanced students of Kant, German idealism and intellectual history.
