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.

Can quite different values be rationally weighed against one another? Can the value of one thing always be ranked as greater than, equal to, or less than the value of something else? If the answer to these questions is no, then in what areas do we find commensurability and comparability unavailable? And what are the implications for moral and legal decision making? This book struggles with these questions, and arrives at distinctly different answers.".

There are many different oughts. There is a moral ought, a prudential ought, an epistemic ought, the legal ought, the ought of etiquette, and so on. These oughts can prescribe incompatible actions. What I morally ought to do may be different from what I self-interestedly ought to do. Philosophers have claimed that these conflicts are resolved by an authoritative ought, or by facts about what one ought to do simpliciter or all-things-considered. However, the only coherent notion of an ought simpliciter (...) has preposterous first-order normative commitments. It is more reasonable to reject the ought simpliciter in favor of the form of normative pluralism advocated in (Tiffany 2007). (shrink)

Offers a critique of prevalent approaches to human good and virtue. Slote shows that typical philosophical accounts of the virtues and human goods oversimplify the subject and that a more exact approach is needed.

Let us give voice to this new demand: we need a critique of moral values, the value of these values should itself, for once, be examined. - Friedrich NietzscheAnyone who, stimulated by education, has come to feel the force of the various obligations in life, at some time or other comes to feel the irksomeness of carrying them out, and to recognize the sacrifice of interest involved; and, if thoughtful, he inevitably puts to himself the question: “Is there really a (...) reason why I should act in the ways in which hitherto I have thought I ought to act? … Should I not really be justified in simply trying to have a good time?” - H.A. Prichard. (shrink)

Henry Sedgewick's The Methods of Ethics challenges comparison, as no other work in moral philosophy, with Aristotle's Ethics in the depth of its understanding of practical rationality, and in its architectural coherence it rivals the work of Kant. In this historical, rather than critical study, Professor Schneewind shows how Sidgewick's arguments and conclusions represent rational developments of the work of Sidgewick's predecessors, and brings out the nature and structure of the reasoning underlying his position.

I begin by proposing and explicating a plausible articulation of the view that morality is overriding. I then argue that it would be desirable for this thesis to be sustained. However, the prospects for its vindication will depend crucially on which moral theory we adopt. I examine some schematic moral theories in order to bring out which are friendly and which unfriendly to moral overridingness. In light of the reasons to hope that the overridingness thesis can be sustained, theories apparently (...) incompatible with it – I argue that consequentialism is one – have a count against them.

: Radical meta-normative skepticism is the view that no standard, norm, or principle has objective authority or normative force. It does not deny that there are norms, standards of correctness, and principles of various kinds that render it possible that we succeed or fail in measuring up to their prerogatives. Rather, it denies that any norm has the status of commanding with objective authority, of giving rise to normative reasons to take seriously and follow its demands. Two powerful transcendental arguments (...) challenge this view. First, skepticism is said to be self-defeating: Settling what to accept, and in particular whether to accept skepticism, appears to be a reason-guided enterprise. How can skeptics coherently support their view by citing reasons in their favor after they just rejected them throughout? Second, there is the practical-deliberative version, most recently developed by David Enoch: We are essentially deliberative creatures. Yet deliberation appears to require that there are correct answers in the form of normative reasons to our practical questions. Thus confidence in the sensible nature of deliberation should inspire confidence in reasons. The essay undermines both transcendental arguments by demonstrating, first, how to support skepticism without deserting its tenets, and, second, how to deliberate in skeptical fashion. (shrink)

This paper is about the rationality of moral action, and so about a problem that is as old as Plato but which still haunts moral philosophy today. It is about the rationality of following morality; of refraining from murder or robbery for instance, and being faithful in keeping contracts and promises, even where this seems to be against our interest and contrary to what we most desire. The problem of the rationality of morality arises most obviously over such actions and (...) therefore has to do particularly with the virtue of justice, because it is here that self-interest and morality often seem to clash. Then reason may represent itself as on the side of self-interest and the fulfilment of present desire; so unless it can be shown that acting justly is a necessary part of practical rationality, cynics like Thrasymachus will always say that there is no good reason to pass up an advantage for the sake of acting justly, and plenty of reason not to pass it up.

A person who sees that she morally ought to do something might wonder whether it would make sense for her to do it. Perhaps Aurelia is on a crowded bus, standing next to an old man whose wallet is almost falling out of his pocket. She says, “I see that the morally right thing would be to warn this man to take care of his wallet. But why should I do the right thing? In fact, why shouldn't I steal his (...) wallet? It would be wrong of me to do this, but so what? No one is looking. I won't get caught. What's to fear?“We can imagine different scenarios of this kind. In one scenario, Aurelia is on the verge of deciding to steal the old man's wallet. She believes it would be wrong to do this, and she is asking whether there is any reason not to go ahead. (shrink)
