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

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.

The Groundwork of the Metaphysics of Morals is Kant's central contribution to moral philosophy, and has inspired controversy ever since it was first published in 1785. Kant champions the insights of 'common human understanding' against what he sees as the dangerous perversions of ethical theory. Morality is revealed to be a matter of human autonomy: Kant locates the source of the 'categorical imperative' within each and every human will. However, he also portrays everyday morality in a way that many readers find difficult to accept. The Groundwork is a short book, but its argument is dense, intricate and at times treacherous. This commentary explains Kant's arguments paragraph by paragraph, and also contains an introduction, a synopsis of the argument, six short interpretative essays on key topics of the Groundwork, and a glossary of key terms. It will be an indispensable tool for anyone wishing to study the Groundwork in detail.

Henry E. Allison presents a comprehensive commentary on Kant's Groundwork for the Metaphysics of Morals (1785). Allison pays special attention to the structure of the work and its historical and intellectual context. He argues that, despite its relative brevity, the Groundwork is the single most important work in modern moral philosophy.
