Published in 1785, the Groundwork of the Metaphysics of Morals is one of the most powerful texts in the history of ethical thought. In this book, Immanuel Kant formulates and justifies a supreme principle of morality that issues universal and unconditional moral commands. These commands receive their normative force from the fact that rational agents autonomously impose the moral law upon themselves. As such, they are laws of freedom. This volume contains the first facing-page German-English edition of Kant's Groundwork. It presents an authentic edition of the German text and a carefully revised version of Mary Gregor's acclaimed English translation, as well as editorial notes and a full bilingual index. It will be the edition of choice for any student or scholar who is not content with reading this central contribution to modern moral philosophy through the veil of English translation.

The Critique of Practical Reason is the second of Kant's three Critiques, and his second work in moral theory after the Groundwork of the Metaphysics of Morals. Its systematic account of the authority of moral principles grounded in human autonomy unfolds Kant's considered views on morality and provides the keystone to his philosophical system. The essays in this volume shed light on the principal arguments of the second Critique and explore their relation to Kant's critical philosophy as a whole. They examine the genesis of the Critique, Kant's approach to the authority of the moral law given as a 'fact of reason', the metaphysics of free agency, the account of respect for morality as the moral motive, and questions raised by the 'primacy of practical reason' and the idea of the 'postulates'. Engaging and critical, this volume will be invaluable to advanced students and scholars of Kant and to moral theorists alike.
