Samuel Kahn’s book is a wide-ranging and provocative discussion of important issues in normative ethics, metaethics and moral psychology. It contains thoughtful and cogent discussions not only of Kant and the Kant literature, but also of contemporary treatments of the moral ought, responsibility and the place of happiness among human ends. Kahn provides an engaging introduction to all these themes.
