Occupying him for more than the last decade of his life, this volume includes the first English translation of Kant's last major work, the so-called Opus postumum, which he described as his "chef d'oeuvre" and the keystone of his entire philosophical system.

Kant is widely acknowledged as the greatest philosopher of modern times. He undertook his famous critical turn to save human freedom and morality from the challenge of determinism and materialism. Intertwined with his metaphysical interests, however, he also had theological commitments, which have received insufficient attention. He believed that man is a fallen creature and in need of ‘redemption’. He intended to provide a fortress protecting religious faith from the failure of rationalist metaphysics, from the atheistic strands of the Enlightenment, from the new mathematical science of nature, and from the dilemmas of Christian theology itself. Kant was an epistemologist, a philosopher of mind, a metaphysician of experience, an ethicist and a philosopher of religion. But all this was sustained by his religious faith. This book aims to recover the focal point and inner contradictions of his thought, the ‘secret thorn’ of his metaphysics (as Heidegger once put it). It first locates Kant in the tradition of reflection on the human weakness from Luther to Hume, and then engages in a critical, but charitable, manner with Kant’s entire pre-critical work, including his posthumous fragments. Special attention is given to The Only Possible Ground (1763), one of the most difficult, interesting and underestimated of Kant’s works. The present book takes its cue from an older approach to Kant, but also engages with recent Anglophone and continental scholarship, and deploys modern analytical tools to make sense of Kant. What emerges is an innovative and thought-provoking interpretation of Kant’s metaphysics, set against the background of forgotten religious aspects of European philosophy.

This volume discusses Kant's philosophical development in the Groundwork and his attempt to justify the categorical imperative as a principle of freedom.

The Groundwork of the Metaphysics of Morals^ is one of the most important works of moral philosophy ever written, and Kant's most widely read work. It attempts to demonstrate that morality has its foundation in reason and that our wills are free from both natural necessity and the power of desire. It is here that Kant sets out his famous and controversial 'categorical imperative', which forms the basis of his moral theory. This book is an essential guide to the groundwork and the many important and profound claims that Kant raises. The book combines an invaluable introduction to the work offering an exploration of these arguments and setting them in the context of Kant's thinking, along with the complete H.J Paton translation of the work, and a selection of six of the best contemporary commentaries. It is the ideal companion for all students of Kantian ethics and anyone interested in moral philosophy. _ _ _
