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.

IN 1959 and 1960 I gave the Gifford Lectures in the University of St. Andrews. The lectures were called 'Norms and Values, an Inquiry into the Conceptual Foundations of Morals and Legislation'. The present work is substantially the same as the content of the second series of lectures, then advertised under the not very adequate title 'Values'. It is my plan to publish a revised version of the content of the first series of lectures, called 'Norms', as a separate book. (...) The two works will be independent of one another. (shrink)

Though the revised edition of A Theory of Justice, published in 1999, is the definitive statement of Rawls's view, so much of the extensive literature on Rawls's theory refers to the first edition. This reissue makes the first edition once again available for scholars and serious students of Rawls's work.

Challenging, with several powerful arguments, some of our deepest beliefs about rationality, morality, and personal identity, Parfit claims that we have a false view about our own nature. It is often rational to act against our own best interersts, he argues, and most of us have moral views that are self-defeating. We often act wrongly, although we know there will be no one with serious grounds for complaint, and when we consider future generations it is very hard to avoid conclusions (...) that most of us will find very disturbing.

This is the first publication of these ideas in book form. 'It is a rare treat--important, original philosophy that is also a pleasure to read.

This is a welcome reprint of a book that continues to grow in importance.

What is the good for human persons? If I am trying to lead the best possible life I could lead, not the morally best life, but the life that is best for me, what exactly am I seeking?This phrasing of the question I will be pursuing may sound tendentious, so some explanation is needed. What is good for one person, we ordinarily suppose, can conflict with what is good for other persons and with what is required by morality. A prudent (...) person seeks her own good efficiently; she selects the best available means to her good. If we call the value that a person seeks when she is being prudent “prudential value,” then an alternative rendering of the question to be addressed in this essay is “What is prudential value?” We can also say that an individual flourishes or has a life high in well-being when her life is high in prudential value. Of course, these common-sense appearances that the good for an individual, the good for other persons, and the requirements of morality often are in conflict might be deceiving. For all that I have said here, the correct theory of individual good might yield the result that sacrificing oneself for the sake of other people or for the sake of a morally worthy cause can never occur, because helping others and being moral always maximize one's own good. But this would be the surprising result of a theory, not something we should presuppose at the start of inquiry. When a friend has a baby and I express a conventional wish that the child have a good life, I mean a life that is good for the child, not a life that merely helps others or merely respects the constraints of morality. After all, a life that is altruistic and perfectly moral, we suppose, could be a life that is pure hell for the person who lives it—a succession of horrible headaches marked by no achievements or attainments of anything worthwhile and ending in agonizing death at a young age. So the question remains, what constitutes a life that is good for the person who is living it? (shrink)

One of Hume's most well-known works and a masterpiece of philosophy, A Treatise of Human Nature is indubitably worth taking the time to read.

I offer an account of how ideals motivate us. My account suggests that although emulating an ideal is often rational, it can lead us to do irrational things. * This is the third in a series of four papers on narrative self-conceptions and their role in moral motivation. In the first paper, “The Self as Narrator” (to appear in Autonomy and the Challenges to Liberalism: New Essays, ed. Joel Anderson and John Christman), I explore the motivational role of narrative self-conceptions, (...) drawing on Daniel Dennett’s notion of the self as a “center of narrative gravity”. In the second paper, “Willing the Law” (in Practical Conflicts, ed. Monika Betzler and Peter Baumann [Cambridge: Cambridge University Press, forthcoming]), I explore the role of selfconceptions in Kantian “conflicts in the will”, drawing on Christine Korsgaard’s notion of “practical identities”. In a fourth paper, “A Sense of Self” (ms), I explore the role of narrative self-con-ceptions in Kantian “conflicts in conception”, drawing on the work of Thomas Nagel and John Perry on the self.

What is the Moral Problem? NORMATIVE ETHICS VS. META-ETHICS It is a common fact of everyday life that we appraise each others' behaviour and attitudes from ...

In this paper I try to undermine complacency with a predominant conception of desire, for the sake of refocusing attention on a philosophical problem. The predominant conception holds that to have a desire is to occupy an evaluative outlook, a perspective from which the agent 'sees' the world in practically salient terms. I argue that it is not clear what this theory is a theory of, because the concept of desire at its center is deeply ambiguous. Understood as a theory (...) of desire in what I call the "placeholder" sense, the evaluative outlook theory is at bottom a theory of action explanation. So construed, its claim is relatively uncontroversial, and falls far short of being a full theory of action explanation. Understood as a theory of desire in what I call the "substantive" sense, it does not even go so far as to acknowledge the central problem such a theory has to answer. That problem is how we can be passive (in a particular sense) with respect to our own motivation. (shrink)

Does action always arise out of desire? G. F. Schueler examines this hotly debated topic in philosophy of action and moral philosophy, arguing that once two senses of "desire" are distinguished - roughly, genuine desires and pro attitudes - apparently plausible explanations of action in terms of the agent's desires can be seen to be mistaken. Desire probes a fundamental issue in philosophy of mind, the nature of desires and how, if at all, they motivate and justify our actions. At (...) least since Hume argued that reason "is and of right ought to be the slave of the passions," many philosophers have held that desires play an essential role both in practical reason and in the explanation of intentional action. G. F. Schueler looks at contemporary accounts of both roles in various belief-desire models of reasons and explanation and argues that the usual belief-desire accounts need to be replaced. Schueler contends that the plausibility of the standard belief-desire accounts rests largely on a failure to distinguish "desires proper," like a craving for sushi, from so-called "pro attitudes," which may take the form of beliefs and other cognitive states as well as desires proper. Schueler's "deliberative model" of practical reasoning suggests a different view of the place of desire in practical reason and the explanation of action. He holds that we can arrive at an intention to act by weighing the relevant considerations and that these may not include desires proper at all. (shrink)

To desire is to be in a particular state of mind. It is a state of mind familiar to everyone who has ever wanted to drink water or desired to know what has happened to an old friend, but its familiarity does not make it easy to give a theory of desire. Controversy immediately breaks out when asking whether wanting water and desiring knowledge are, at bottom, the same state of mind as others that seem somewhat similar: wishing never to (...) have been born, preferring mangoes to peaches, craving gin, having world conquest as one's goal, having a purpose in sneaking out to the shed, or being inclined to provoke just for the sake of provocation. These varied states of mind have all been grouped together under the heading of ‘pro attitudes’, but whether the pro attitudes are fundamentally one mental state or many is disputed. (shrink)

Desires move us to action, give us urges, incline us to joy at their satisfaction, and incline us to sorrow at their frustration. Naturalistic work on desire has focused on distinguishing which of these phenomena are part of the nature of desire, and which are merely normal consequences of desiring. Three main answers have been proposed. The first holds that the central necessary fact about desires is that they lead to action. The second makes pleasure the essence of desire. And (...) the third holds that the central necessary fact about desires is that they open us to reward-based learning. (shrink)

Proponents of numerous recent theories of a person's good hold that a plausible account of the good for a person must satisfy existence internalism. Yet little direct defense has been given for this position. I argue that the principal intuition behind internalism supports a stronger version of the thesis than it might appear--one that effects a "double link" to motivation. I then identify and develop the main arguments that have been or might be given in support of internalism about a (...) person's good, showing how these arguments support this stronger version of internalism.

Leading versions of hedonism generate implausible results about the welfare value of very intense or unwanted pleasures, while recent versions of desire satisfactionism overvalue the fulfillment of desires associated with compulsions and addictions. Consequently, both these theories fail to satisfy a plausible condition of adequacy for theories of well-being proposed by L.W. Sumner: they do not make one’s well-being depend on one’s own cares or concerns. But Sumner’s own life-satisfaction theory cannot easily be extended to explain welfare over time, and (...) it makes mistaken (autonomous, informed) self-assessment impossible. A new account of well-being based on the stable realization of personal values enjoys the advantages claimed for these subjective theories while avoiding these problems. (shrink)

Owing to a genral dissatisfaction with hedonistic theories of value, a number of recent discussions have sought to identify an agent's selfinterest, individual utility, or personal welfare with what the agent most wants to do, all things considered. Two features of these accounts merit special attention for the argument in this paper. First, on such accounts any desire or aversion which persists in the face of complete information is logically relevant to the determination of an agent's self interest. This includes (...) apparently altruistic desires like a desire for another's happiness as well as more narrow and self-regarding desires like a desire to eat a good meal. Second, when the agent finds himself in a situation where he must choose between incompatible desires, his informed preference determines the act which is most in his self-interest. (shrink)

Desire-based theories of well-being claim that a person's well-being consists of the satisfaction of her desires. Many of these theories say that well-being consists of the satisfaction of desires that she would have if her desires were "corrected" in various ways. Some versions of this theory claim that the corrections involve having "full information" or being an "ideal observer." I argue that well-being does not depend on what one would desire if she were an “ideal observer.” Rather, it depends on (...) what she would desire if she had as much information as she could have and still maintain her identity as the particular person she is. The paper attempts to spell out this suggestion by constructing a notion of integrity. Roughly, integrity is preserved if one’s most central projects, commitments, and character traits are left in tact. I argue that desire-based theories of well-being should define well-being in terms of the satisfaction of those desires that one would have if one’s epistemic situation were idealized as much as would be consistent with maintaining her integrity.

Just as there are rational requirements on thought, there are rational requirements on action. This book defends a conception of ethics, and a related conception of human nature, according to which altruism is included among the basic rational requirements on desire and action. Altruism itself depends on the recognition of the reality of other persons, and on the equivalent capacity to regard oneself as merely one individual among many.

It seems to be a widely shared view that any defensible desire-fulfillment theory of welfare must be framed not in terms of what an agent, in fact, desires but rather in terms of what an agent would desire under hypothetical conditions that include improved information. Unfortunately, though, such accounts are subject to serious criticisms. In this paper I show that in the face of these criticisms the best response is to jettison any appeal to idealized information conditions: the considerations put (...) forward in support of the appeal to what would be desired in hypothetical circumstances of improved information do not, in fact, give adequate reason to make that appeal. (shrink)

It is commonly thought that subjectivists about welfare must claim that the favorable attitudes whose satisfaction is relevant to your well-being are those that you would have in idealized conditions (e.g. ones in which you are fully informed and rational). I argue that this is false. I introduce a non-idealizing subjectivist view, Same World Subjectivism, that accommodates the two main rationales for idealizing: those given by Peter Railton and David Sobel. I also explain why a recent argument from Dale Dorsey (...) fails to show that subjectivists must idealize. Because Same World Subjectivism is a plausible non-idealizing view, subjectivists about welfare needn't idealize. (shrink)

A subjective list theory of well-being is one that accepts both pluralism (the view that there is more than one basic good) and subjectivism (the view, roughly, that every basic good involves our favourable attitudes). Such theories have been neglected in discussions of welfare. I argue that this is a mistake. I introduce a subjective list theory called disjunctive desire satisfactionism, and I argue that it is superior to two prominent monistic subjectivist views: desire satisfactionism and subjective desire satisfactionism. In (...) the course of making this argument, I introduce a problem for desire satisfactionism: it cannot accommodate the fact that whenever someone experiences an attitudinal pleasure, his welfare is (other things equal) higher during the pleasure. Finally, I argue that any subjectivist about welfare should find disjunctive desire satisfactionism highly attractive. (shrink)

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

When we compare contemporary moral philosophy with the well-known moral systems of earlier centuries, we should be struck by the fact that a certain assumption about human well being that is now widely taken for granted was universally rejected in the past. The contemporary moral climate predisposes us to be pluralistic about the human good, whereas earlier systems of ethics embraced a conception of well being that we would now call narrow and restrictive. One way to convey the sort of (...) contrast I have in mind is to note that according to Plato and Aristotle, there is one kind of life, that of the philosopher, that represents the summit of human flourishing, and all other lives are worth leading to the extent that they approximate this ideal. Certain other ethical theories of the past were in a way more narrow than this, for whereas Plato and Aristotle maintained that many things are in themselves worthwhile, others argued that there is only one intrinsic good—pleasure according to the Epicureans, virtue according to the Stoics. By contrast, it is now widely assumed that all such approaches are too exclusive, that not only are there many types of intrinsic goods but there is no one specific kind of life—whether it is that of a philosopher or a poet or anyone else—that is the single human ideal. Even hedonism, a conception of the good that had a powerful influence in the modern period, has few contemporary proponents. A consensus has arisen in our time that there is no single ultimate good that provides the measure by which the worth of all other goods must be assessed. (shrink)

This paper responds to a new objection, due to Ben Bramble, against attitudinal theories of sensory pleasure and pain: the objection from unconscious pleasures and pains. According to the objection, attitudinal theories are unable to accommodate the fact that sometimes we experience pleasures and pains of which we are, at the time, unaware. In response, I distinguish two kinds of unawareness and argue that the subjects in the examples that support the objection are unaware of their sensations in only a (...) weak sense, and this weak sort of unawareness of a sensation does not preclude its being an object of one’s attitudes. (shrink)

One of the leading approaches to the nature of sensory pleasure reduces it to desire: roughly, a sensation qualifies as a sensation of pleasure just in case its subject wants to be feeling it. This approach is, in my view, correct, but it has never been formulated quite right; and it needs to be defended against some compelling arguments. Thus the purpose of this paper is to discover the most defensible formulation of this rough idea, and to defend it against (...) the most interesting objections. (shrink)

The desire-satisfaction theory of welfare says, roughly, that one's life goes well to the extent that one's desires are satisfied. On standard 'actualist' versions of the theory, it doesn't matter what you desire. So long as you are getting what you actually want – whatever it is – things are going well for you. There is widespread agreement that these standard versions are incorrect, because we can desire things that are bad for us -– in other words, because there are (...) 'defective desires'. The aim of this paper is to defend the actualist desire-satisfaction theory against the problem of defective desires. I aim to show how the theory can accommodate the obvious fact that we can desire things that are bad for us. Admittedly, there are kinds of allegedly defective desire the theory cannot accommodate, but these desires, I argue, turn out not to be defective in the relevant way. (shrink)
