In recent years there has been renewed interest in the “Doctrine of Virtue”, the ethical part of Kant’s late systematic treatise on moral philosophy, the Metaphysics of Morals. The present volume responds to these demands. Following a series of research workshops, 18 scholars from Germany, Italy, Britain and the United States provide a seamless commentary on the “Doctrine of Virtue”, discussing topics such as suicide, truthfulness, moral perfection, beneficence, gratitude, sympathy, respect and friendship as well as Kant’s moral psychology, philosophy of action and theory of moral education. This book will be an invaluable resource for moral philosophers and Kant scholars alike.
