Book excerpt: 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. _ _ _
