Kant’s Metaphysics of Morals: A Critical Guide is a collection of new essays by established and distinguished scholars on central topics in Kant’s Metaphysics of Morals. The anthology is part of the Cambridge University Press “Critical Guide” series, which aims at essays that break new ground and advance critical discussion of canonical philosophical texts. Many of the essays in this volume do just that. There are essays on the Introduction to the Metaphysics of Morals, the Doctrine of Right, and the Doctrine of Virtue. The volume is not intended as a cooperative commentary on the entire book, but it does provide a fairly comprehensive guide to interpretive and philosophical questions raised by the Metaphysics of Morals, including its relation to theGroundwork and Critique of Practical Reason.
