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.

A scholarly edition of a work by David Hume. The edition presents an authoritative text, together with an introduction, commentary notes, and scholarly apparatus.

Contemporary realist theories of value claim to be compatible with natural science. In this paper, I call this claim into question by arguing that Darwinian considerations pose a dilemma for these theories. The main thrust of my argument is this. Evolutionary forces have played a tremendous role in shaping the content of human evaluative attitudes. The challenge for realist theories of value is to explain the relation between these evolutionary influences on our evaluative attitudes, on the one hand, and the (...) independent evaluative truths that realism posits, on the other. Realism, I argue, can give no satisfactory account of this relation. On the one hand, the realist may claim that there is no relation between evolutionary influences on our evaluative attitudes and independent evaluative truths. But this claim leads to the implausible skeptical result that most of our evaluative judgements are off track due to the distorting pressure of Darwinian forces. The realist’s other option is to claim that there is a relation between evolutionary influences and independent evaluative truths, namely that natural selection favored ancestors who were able to grasp those truths. But this account, I argue, is unacceptable on scientific grounds. Either way, then, realist theories of value prove unable to accommodate the fact that Darwinian forces have deeply influenced the content of human values. After responding to three objections, the third of which leads me to argue against a realist understanding of the disvalue of pain, I conclude by sketching how antirealism is able to sidestep the dilemma I have presented. Antirealist theories of value are able to offer an alternative account of the relation between evolutionary forces and evaluative facts —
an account that allows us to reconcile our understanding of evaluative truth with our understanding of the many non-rational causes that have played a role in shaping our evaluative judgements. (shrink)

This article argues that strong versions of the situationist critique of virtue ethics are empirically and conceptually unfounded, as well as that, even if one accepts that the predictive power of character may be limited, this is not a fatal problem for early Confucian virtue ethics. Early Confucianism has explicit strategies for strengthening and expanding character traits over time, as well as for managing a variety of situational forces. The article concludes by suggesting that Confucian virtue ethics represents a more (...) empirically responsible model of ethics than those currently dominant in Western philosophy. (shrink)

I am going to argue that linking Hume’s name with instrumentalism is as inappropriate as linking Aristotle’s: that, as a matter of textual point, the Hume of the Treatise is not an instrumentalist at all, and that the view of practical reasoning that he does have is incompatible with, and far more minimal than, instrumentalism. Then I will consider Hume’s reasons for his view, and argue that they make sense when they are seen against the background of his semantic theory. (...) And finally, I will try to say why it is that Hume has nonetheless been read as he has. (shrink)

Levi’s work in decision theory has for many years been a major influence on the field. His writings have raised important new issues and opened new lines of inquiry. This collection of his papers brings out the range of his recent studies and the close bearing of his work on the work of others.

This essay contains a partial exploration of some key concepts associated with the epistemology of realist philosophies of science. It shows that neither reference nor approximate truth will do the explanatory jobs that realists expect of them. Equally, several widely-held realist theses about the nature of inter-theoretic relations and scientific progress are scrutinized and found wanting. Finally, it is argued that the history of science, far from confirming scientific realism, decisively confutes several extant versions of avowedly 'naturalistic' forms of scientific (...) realism.

Instead of conceiving ethical commands as divine revelations or as the discoveries of brilliant thinkers, we should see our ethical practices as evolving over tens of thousands of years, as members of our species have worked out how to live together and prosper. Here, Kitcher elaborates his radical vision of this millennia-long ethical project.

Most people believe that there are limits to the sacrifices that morality can demand. Although it would often be meritorious, we are not, in fact, morally required to do all that we can to promote overall good. What's more, most people also believe that certain types of acts are simply forbidden, morally off limits, even when necessary for promoting the overall good. In this provocative analysis Kagan maintains that despite the intuitive appeal of these views, they cannot be adequately defended. (...) In criticizing arguments for limited moral requirements as well as those for unconditionally prohibited acts, Kagan offers a sustained attack on two of the most basic features of ordinary common sense morality.

Metaethical—or, more generally, metanormative— realism faces a serious epistemological challenge. Realists owe us—very roughly speaking—an account of how it is that we can have epistemic access to the normative truths about which they are realists. This much is, it seems, uncontroversial among metaethicists, myself included. But this is as far as the agreement goes, for it is not clear—nor uncontroversial—how best to understand the challenge, what the best realist way of coping with it is, and how successful this attempt is. (...) In this paper I try, first, to present the challenge in its strongest version, and second, to show how realists—indeed, robust realists—can cope with it. The strongest version of the challenge is, I argue, that of explaining the correlation between our normative beliefs and the independent normative truths. And I suggest an evolutionary explanation as a way of solving it. (shrink)

In his influential book, The Nature of Morality, Gilbert Harman writes: “In explaining the observations that support a physical theory, scientists typically appeal to mathematical principles. On the other hand, one never seems to need to appeal in this way to moral principles.” What is the epistemological relevance of this contrast, if genuine? This chapter argues that ethicists and philosophers of mathematics have misunderstood it. They have confused what the chapter calls the justificatory challenge for realism about an area, D—the (...) challenge to justify our D-beliefs—with the reliability challenge for D-realism—the challenge to explain the reliability of our D-beliefs. Harman’s contrast is relevant to the first, but not, evidently, to the second. One upshot of the discussion is that genealogical debunking arguments are fallacious. Another is that indispensability considerations cannot answer the Benacerraf–Field challenge for mathematical realism. (shrink)

I argue that by constructing an identity of Bohemian whim and spontaneity one can make what was previously an akratic action into a fully rational action, since in performing the action, one asserts one identity.

In this paper I am not so much concerned with movements of the mind, as movements of the will. But my question bears a similarity to that of the tortoise. I want to ask whether the will is under the control of fact and reason, combined. I shall try to show that there is always something else, something that is not under the control of fact and reason, which has to be given as a brute extra, if deliberation is ever (...) to end by determining the will. This is, of course, a Humean conclusion, and the only novelty comes in the way I wish to argue for it. I believe that many philosophers think, erroneously, that Hume relies on a naive and outdated conception of facts, or on an even more naive and outdated conception of reason, in order to put passion on their throne. My tortoise defends Hume: what we do with our premises is not itself construed as acceptance of a premise. As it stands the project is only described metaphorically. Presumably everything, including movement of the will, is under the control of facts in some sense, for even if they are only facts about our physiology or chemistry, still, they make us move. I am interested only in cognitive control, or control by the apprehension of fact and reason. (shrink)

Reductionist forms of moral realism, such as naturalist realism, are often thought immune to epistemological objections that have been raised against nonnaturalist realism in the form of reliability worries or evolutionary debunking arguments. This article establishes that reductionist realist views can only explain the reliability of our moral beliefs at the cost of incurring repugnant first-order conclusions.

Ethics appears early in the life of a culture. It is not the creation of philosophers. Many philosophers today think that their job is to take the ethics of their society in hand, analyse it into parts, purge the bad ideas, and organize the good into a systematic moral theory. The philosophers' ethics that results is likely to be very different from the culture's raw ethics and, they think, being better, should replace it. But few of us, even among philosophers, (...) settle real-life moral questions by consulting the Categorical Imperative or the Principle of Utility, largely because, if we do, we often do not trust the outcome or cannot even reliably enough decide what it is. By contrast, James Griffin explores the question what philosophers can reasonably expect to contribute to normative ethics or to the ethics of a culture. Griffin argues that moral philosophers must tailor their work to what ordinary humans' motivational capabilities, and he offers a new account of moral deliberation. (shrink)

Ockham's razor, the principle of parsimony, states that simpler theories are better than theories that are more complex. It has a history dating back to Aristotle and it plays an important role in current physics, biology, and psychology. The razor also gets used outside of science - in everyday life and in philosophy. This book evaluates the principle and discusses its many applications. Fascinating examples from different domains provide a rich basis for contemplating the principle's promises and perils. It is (...) obvious that simpler theories are beautiful and easy to understand; the hard problem is to figure out why the simplicity of a theory should be relevant to saying what the world is like. In this book, the ABCs of probability theory are succinctly developed and put to work to describe two 'parsimony paradigms' within which this problem can be solved. (shrink)

It is often claimed that irreducibly normative truths would have unacceptable metaphysical implications, and are incompatible with a scientific view of the world. The book argues, on the basis of a general account of the relevance of ontological questions, that this claim is mistaken. It is also a mistake to think that interpreting normative judgments as beliefs would make it impossible to explain their connection with action. An agent’s acceptance of a normative judgment can explain that agent’s subsequent action because (...) it is part of being a rational agent that such an agent’s beliefs about reasons normally, but not invariably, make a difference to the agent’s subsequent behavior. Because facts about reasons are not entities existing apart from us, there is no epistemological problem of how we can “be in touch with” such facts. There are serious worries about normative knowledge, but the problems involved are internal to the normative domain itself. The best solution to these problems would be an overall account of the domain of reasons in normative terms, supported by an argument from reflective equilibrium. But no existing account, constructivist, or based on desires or on an idea of rationality, is plausible, and no alternative is likely to succeed. Conclusions about reasons for action must rest on more piecemeal applications of the method of reflective equilibrium. (shrink)

In these essays, distinguished philosopher Philip Kitcher argues for a reconstruction of philosophy along the lines of classical Pragmatism.

The modern materialist approach to life has conspicuously failed to explain such central mind-related features of our world as consciousness, intentionality, meaning, and value. This failure to account for something so integral to nature as mind, argues philosopher Thomas Nagel, is a major problem, threatening to unravel the entire naturalistic world picture, extending to biology, evolutionary theory, and cosmology. Since minds are features of biological systems that have developed through evolution, the standard materialist version of evolutionary biology is fundamentally incomplete. (...) And the cosmological history that led to the origin of life and the coming into existence of the conditions for evolution cannot be a merely materialist history, either. An adequate conception of nature would have to explain the appearance in the universe of materially irreducible conscious minds, as such. Nagel's skepticism is not based on religious belief or on a belief in any definite alternative. In Mind and Cosmos, he does suggest that if the materialist account is wrong, then principles of a different kind may also be at work in the history of nature, principles of the growth of order that are in their logical form teleological rather than mechanistic. In spite of the great achievements of the physical sciences, reductive materialism is a world view ripe for displacement. Nagel shows that to recognize its limits is the first step in looking for alternatives, or at least in being open to their possibility. (shrink)

Moral thinking pervades our practical lives, but where did this way of thinking come from, and what purpose does it serve? Is it to be explained by environmental pressures on our ancestors a million years ago, or is it a cultural invention of more recent origin? In The Evolution of Morality, Richard Joyce takes up these controversial questions, finding that the evidence supports an innate basis to human morality. As a moral philosopher, Joyce is interested in whether any implications follow (...) from this hypothesis. Might the fact that the human brain has been biologically prepared by natural selection to engage in moral judgment serve in some sense to vindicate this way of thinking--staving off the threat of moral skepticism, or even undergirding some version of moral realism? Or if morality has an adaptive explanation in genetic terms--if it is, as Joyce writes, "just something that helped our ancestors make more babies"--might such an explanation actually undermine morality's central role in our lives? He carefully examines both the evolutionary "vindication of morality" and the evolutionary "debunking of morality," considering the skeptical view more seriously than have others who have treated the subject.Interdisciplinary and combining the latest results from the empirical sciences with philosophical discussion, The Evolution of Morality is one of the few books in this area written from the perspective of moral philosophy. Concise and without technical jargon, the arguments are rigorous but accessible to readers from different academic backgrounds. Joyce discusses complex issues in plain language while advocating subtle and sometimes radical views. The Evolution of Morality lays the philosophical foundations for further research into the biological understanding of human morality. (shrink)

A volume of philosophical studies, centred on problems of personal identity and extending to related topics in the philosophy of mind and moral philosophy.

Through his S–R model of statistical relevance, Wesley Salmon offers a solution to the scientific explanation of objectively improbable events.

Isaac Levi is one of the preeminent philosophers in the areas of pragmatic rationality and epistemology. This collection of essays constitutes an important presentation of his original and influential ideas about rational choice and belief. A wide range of topics is covered, including consequentialism and sequential choice, consensus, voluntarism of belief, and the tolerance of the opinions of others. The essays elaborate on the idea that principles of rationality are norms that regulate the coherence of our beliefs and values with (...) our rational choices. The norms impose minimal constraints on deliberation and inquiry, but they also impose demands well beyond the capacities of deliberating agents. This major collection will be eagerly sought out by a wide range of philosophers in epistemology, logic, and philosophy of science, as well as economists, decision theorists, and statisticians.

This collection of eleven papers by Elijah Millgram (nine of which have been previously published) is ostensibly united by the thesis that the best way to go about assessing moral theories is to identify the view of practical reasoning that each such theory rests upon, and evaluate the adequacy of these respective theories of practical reasoning. The correct moral theory, Millgram assures us, will be the one that is paired with the best theory of practical reasoning. He outlines this methodology (...) in a substantial (32 pp.) introduction. Why should we adopt Millgram’s method? A host of concerns immediately leap to mind. If two or more different moral theories rest on the same theory of practical reasoning, then how would discovering the latter to be the correct theory of practical reasoning help us decide among the moral theories? What if a given moral theory is consistent with two or more different theories of practical reasoning? What if we cannot evaluate theories of practical reasoning independently of having adopted a moral perspective? Millgram doesn’t address these natural questions head on, but rather proposes that the essays of the volume collectively constitute a “feasibility demonstration” (p. 3) of the method. In other words, the only way that we will be persuaded that the pairings between moral theories and practical reasoning theories are tight enough to support this grand project is to get our hands dirty in detailed discussion of particular moral theories, particular theories of practical reasoning, and the relations between them. It is through seeing the method at work that we will become convinced, Millgram hopes, of several interlocking theses: (1) that each of the major moral theories of the past has had a distinctive take on practical reasoning; (2) that pivotal structural elements of these theories are due to the underlying theory of practical reasoning; (3) that problems in a moral theory can often be traced to problems in the underlying theory of practical reasoning; (4) that theories of practical reasoning are “engines” (p..
