Studies of Kant's moral and political philosophy have increasingly focused on his last major work in ethics, The Metaphysics of Morals. This work is here discussed in seventeen essays by leading contemporary Kant scholars, most of them specially written for this volume. They cover a broad range of topics, including Kant's views on rights, punishment, contract, practical reasoning, revolution, freedom, virtue, legislation, happiness, moral judgement, love, respect, duties to oneself, and motivation. This is the only book devoted entirely to The Metaphysics of Morals and is not just a landmark in Kant studies but also a significant contribution to contemporary moral and political philosophy.
