Moral Realism is a systematic defence of the idea that there are objective moral standards. Russ Shafer-Landau argues that there are moral principles that are true independently of what anyone, anywhere, happens to think of them. His central thesis, as well as the many novel supporting arguments used to defend it, will spark much controversy among those concerned with the foundations of ethics.

John Mackie's stimulating book is a complete and clear treatise on moral theory. His writings on normative ethics-the moral principles he recommends-offer a fresh approach on a much neglected subject, and the work as a whole is undoubtedly a major contribution to modern philosophy.The author deals first with the status of ethics, arguing that there are not objective values, that morality cannot be discovered but must be made. He examines next the content of ethics, seeing morality as a functional device, (...) basically the same at all times but changing significantly in response to changes in the human condition. He sketches a practical moral system, criticizing but also borrowing from both utilitarian and absolutist views. Thirdly, the frontiers of ethics, areas of contact with psychology, metaphysics, theology, law and politcs, are explored.Throughout, his aim is to discuss a wide range of questions that are both philosophical and practical, working within a distinctive version of subjectivism-an "error" theory of the apparent objectivity of values. John Mackie has drawn on the contributions of such classic thinkers as Plato, Aristotle, Hobbes, Hume, Kant and Sidgwick, and on more recent discussions, to produce a thought-provoking account that will inspire both the general reader and the student of philosophy.

This volume is devoted to Lewis's work in ethics and social philosophy. Topics covered include the logic of obligation and permission; decision theory and its relation to the idea that beliefs might play the motivating role of desires; a subjectivist analysis of value; dilemmas in virtue ethics; the problem of evil; problems about self-prediction; social coordination, linguistic and otherwise; alleged duties to rescue distant strangers; toleration as a tacit treaty; nuclear warfare; and punishment. This collection, and the two preceding volumes, (...) will disseminate more widely the work of an eminent and influential contemporary philosopher. (shrink)

Argues for the humean theory of motivation on the grounds that rejecting it requires rejecting decision theory.

"[This book] proposes new foundations for the Bayesian principle of rational action, and goes on to develop a new logic of desirability and probabtility."—Frederic Schick, _Journal of Philosophy_.

The book asks how, and how much, we can improve our ethical standards—not lift our behaviour closer to our standards but refine the standards themselves. To answer this question requires answering most of the major questions of ethics. So the book includes a discussion of what a good life is like, where the bounds of the natural world come, how values relate to that world (e.g. naturalism, realism), how great human capacities—the ones important to ethics—are, and where moral norms come (...) from. Throughout the book, the question of what philosophy can contribute to ethics arises. Philosophical traditions, such as most forms of utilitarianism, deontology, and virtue ethics, are, the book contends, too ambitious. Ethics cannot be what philosophers in those traditions expect it to be because agents cannot be what these philosophies require them to be. The book starts by questioning the adequacy of both appeals to intuition and the coherence method of justification in ethics (e.g. wide reflective equilibrium) and ends with a description of the sort of justification available to us.

This paper contributes to the mathematical foundations of the model for utility theory developed by Richard Jeffrey in The Logic of Decision [5]. In it I discuss the relationship of Jeffrey's to classical models, state and interpret an existence theorem for numerical utilities and subjective probabilities and restate a theorem on their uniqueness.

Classic analysis of the subject and the development of personal probability; one of the greatest controversies in modern statistcal thought.

This 1991 book is about the continuing influence of Hume's ideas on moral and political philosophy. In part, it is a critical exegesis of Hume's most impressive and challenging doctrines in Book III of the Treatise of Human Nature on such topics as morals, motivation, justice, and social institutions. However, the main thrust of the argument is to throw into relief the importance of that discussion for contemporary philosophy. While the author subjects most contemporary defences of Humean doctrines to intense (...) criticism, he also seeks to discover what versions of Hume's theories might still be defensible and viable.

According to moral relativism, there is not a single true morality. There are a variety of possible moralities or moral frames of reference, and whether something is morally right or wrong, good or bad, just or unjust, etc. is a relative matter—relative to one or another morality or moral frame of reference. Something can be morally right relative to one moral frame of reference and morally wrong relative to another. It is useful to compare moral relativism to other relativisms. One (...) possible comparison is with motion relativism. There is no such thing as absolute motion or absolute rest. Whether something is moving or at rest is relative to a spatio-temporal frame of reference. Something may be at rest in one frame of reference and moving in another. There is no such thing as absolute motion and absolute rest, but we can make do with relative motion and rest. Similarly, moral relativism is the view that, although there is no such thing as absolute right and wrong, we can make do with relative right and wrong. (shrink)
