This is a major work in moral philosophy, the long-awaited follow-up to Parfit's 1984 classic Reasons and Persons, a landmark of twentieth-century philosophy. Parfit now presents a powerful new treatment of reasons and a critical examination of the most prominent systematic moral theories, leading to his own ground-breaking conclusion.

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. (shrink)

An introductory guide to the seminal work of Kant and his modern moral philosophy.

Two centuries after they were published, Kant's ethical writings are as much admired and imitated as they have ever been, yet serious and long-standing accusations of internal incoherence remain unresolved. Onora O'Neill traces the alleged incoherences to attempts to assimilate Kant's ethical writings to modern conceptions of rationality, action and rights. When the temptation to assimilate is resisted, a strikingly different and more cohesive account of reason and morality emerges. Kant offers a "constructivist" vindication of reason and a moral vision (...) in which obligations are prior to rights and in which justice and virtue are linked. O'Neill begins by reconsidering Kant's conceptions of philosophical method, reason, freedom, autonomy and action. She then moves on to the more familiar terrain of interpretation of the Categorical Imperative, while in the last section she emphasizes differences between Kant's ethics and recent "Kantian" ethics, including the work of John Rawls and other contemporary liberal political philosophers.

Henry E. Allison presents a comprehensive commentary on Kant's Groundwork for the Metaphysics of Morals. 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.

Christine Korsgaard has become one of the leading interpreters of Kant's moral philosophy. She is identified with a small group of philosophers who are intent on producing a version of Kant's moral philosophy that is at once sensitive to its historical roots while revealing its particular relevance to contemporary problems. She rejects the traditional picture of Kant's ethics as a cold vision of the moral life which emphasises duty at the expense of love and value. Rather, Kant's work is seen (...) as providing a resource for addressing not only the metaphysics of morals, but also for tackling practical questions about personal relations, politics, and everyday human interaction. This collection contains some of the finest current work on Kant's ethics and will command the attention of all those involved in teaching and studying moral theory. (shrink)

Many regard Kant’s account of the highest good as a failure. His inclusion of happiness in the highest good, in combination with his claim that it is a duty to promote the highest good, is widely seen as inconsistent. In this essay, I argue that there is a valid argument, based on premises Kant clearly endorses, in defense of his thesis that it is a duty to promote the highest good. I first examine why Kant includes happiness in the highest (...) good at all. On the basis of a discussion of Kant's distinction between 'good' and 'pleasant', and in light of his methodological comments in the second chapter of the Critique of Practical Reason, I explain how Kant’s conception of the good informs his conception of the highest good. I then argue that Kant's inclusion of happiness in the highest good should be understood in light of his claim that it is a duty to promote the happiness of others. In the final section of this essay, I reconstruct Kant’s argument for the claim that it is a duty to promote the highest good and explain in what sense this duty goes beyond observance of the Categorical Imperative.

This is a major new study of Kant's ethics that will transform the way students and scholars approach the subject in future. Allen Wood argues that Kant's ethical vision is grounded in the idea of the dignity of the rational nature of every human being. Undergoing both natural competitiveness and social antagonism the human species, according to Kant, develops the rational capacity to struggle against its impulses towards a human community in which the ends of all are to harmonize and (...) coincide. The distinctive features of the book are twofold. First, it focuses for the first time on the central role played in Kant's ethical theory by the value of rational nature as an end itself. Second, it shows the importance of Kant's systematic theory of human nature and history, and its implications for the structure, formulation, and application of Kant's moral principles. This comprehensive study will be of critical importance to students of moral philosophy, the history of ideas, political theory, and religious studies. (shrink)

In this book, Allen Wood investigates Kant's conception of ethical theory, using it to develop a viable approach to the rights and moral duties of human beings. By remaining closer to Kant's own view of the aims of ethics, Wood's understanding of Kantian ethics differs from the received 'constructivist' interpretation, especially on such matters as the ground and function of ethical principles, the nature of ethical reasoning and autonomy as the ground of ethics. Wood does not hesitate to criticize and (...) modify Kant's conclusions when they seem inconsistent with his basic principles or fail to make the best use of the resources Kantian principles make available. Of special interest are the book's treatment of such topics as freedom of the will, the state's role in securing economic justice, sexual morality, the justification of punishment, and the prohibition on lying.

Kantians are increasingly deserting the universal law formula in favor of the humanity formula. The former, they argue, is open to various decisive objections; the two are not equivalent; and it is only by appealing to the humanity formula that Kant can reliably generate substantive implications from his theory of an acceptable sort. These assessments of the universal law formula, which clash starkly with Kant's own assessment of it, are based on various widely accepted interpretative assumptions. These assumptions, it is (...) argued in this article, depend on misleading translations of key terms; selective attention to Kant's concrete examples; not taking seriously Kant's theoretical claims about the relations among his various ideas; and a failure to take into account Kant's idiosyncratic definitions of key concepts. The article seeks to right these interpretative wrongs, and finds that the universal law formula is not open to many of the standard objections. (shrink)

Andrews Reath presents a selection of his best essays on various features of Kant's moral psychology and moral theory, with particular emphasis on his conception of rational agency and his conception of autonomy. Together the essays articulate Reath's original approach to Kant's views about human autonomy, which explains Kant's belief that objective moral requirements are based on principles we choose for ourselves. With two new papers, and revised versions of several others, the volume will be of great interest to all (...) students and scholars of Kant and of moral philosophy. (shrink)

In the Preface to his best known work on moral philosophy, Kant states his purpose very clearly and succinctly: “The present groundwork is, however, nothing more than the search for and establishment of the supreme principle of morality, which already constitutes an enterprise whole in its aim and to be separated from every other moral investigation” (Groundwork 4:392). This paper will deal with the outcome of the first part of this task, namely, Kant’s attempt to formulate the supreme principle of (...) morality, which is the intended outcome of the search. It will consider this formulation in light of Kant’s conception of the historical antecedents of his attempt. (shrink)
