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

First published in 2012. Kant’s Groundwork of the Metaphysic of Morals is one of the small books which are truly great: it has exercised on human thought an influence almost ludicrously disproportionate to its size. In moral philosophy it ranks with the ‘Republic’ of Plato and the ‘Ethics’ of Aristotle; and perhaps— partly no doubt through the spread of Christian ideals and through the long experience of the human race during the last two thousand years—it shows in some respects a deeper insight even than these. Its main topic—the supreme principle of morality—is of the utmost importance to all who are not indifferent to the struggle of good against evil. Written, as it was, towards the end of the eighteenth century, it is couched in terms other than those that would be used today; but its message was never more needed than it is at present, when a somewhat arid empiricism is the prevailing fashion in philosophy.

Immanuel Kant’s Groundwork for the Metaphysics of Morals is one of the most important texts in the history of ethics. In it Kant searches for the supreme principle of morality and argues for a conception of the moral life that has made this work a continuing source of controversy and an object of reinterpretation for over two centuries. This new edition of Kant’s work provides a fresh translation that is uniquely faithful to the German original and more fully annotated than any previous translation. There are also four essays by well-known scholars that discuss Kant’s views and the philosophical issues raised by the Groundwork. J.B. Schneewind defends the continuing interest in Kantian ethics by examining its historical relation both to the ethical thought that preceded it and to its influence on the ethical theories that came after it; Marcia Baron sheds light on Kant’s famous views about moral motivation; and Shelly Kagan and Allen W. Wood advocate contrasting interpretations of Kantian ethics and its practical implications.

Immanuel Kant's Groundwork of the Metaphysics of Morals of 1785 is one of the most profound and important works in the history of practical philosophy. In this introduction to the Groundwork, Sally Sedgwick provides a guide to Kant's text that follows the course of his discussion virtually paragraph by paragraph. Her aim is to convey Kant's ideas and arguments as clearly and simply as possible, without getting lost in scholarly controversies. Her introductory chapter offers a useful overview of Kant's general approach to practical philosophy, and she also explores and clarifies some of the main assumptions which Kant relies on in his Groundwork but defends in his Critique of Pure Reason. The book will be a valuable guide for all who are interested in Kant's practical philosophy.

Groundwork of the Metaphysics of Morals is the first of Immanuel Kant's mature works on moral philosophy and remains one of the most influential in the field. Kant conceives his investigation as a work of foundational ethics—one that clears the ground for future research by explaining the core concepts and principles of moral theory and showing that they are normative for rational agents.
