We often hear such casual accusations: you just believe that because you are a liberal, a Christian, an American, a woman… When such charges are made they are meant to sting—not just emotionally, but epistemically. But should they? It can be disturbing to learn that one's beliefs reflect the influence of such irrelevant factors. The pervasiveness of such influence has led some to worry that we are not justified in many of our beliefs. That same pervasiveness has led others to (...) doubt whether there is any worry here at all. I argue that evidence of irrelevant belief influence is sometimes, but not always, undermining. My proposal picks out ordinary, non-skeptical cases in which we get evidence of error. It says that, in those cases, evidence of irrelevant influence is epistemically significant. It shows how respecting evidence of error is compatible with the epistemic lives we see ourselves living. We are fallible creatures, yes, but we are also capable and intelligent ones. We can recognize and correct for our own error so as to improve our imperfect, yet nevertheless robust, epistemic lives. (shrink)

Moral disagreement is widely held to pose a threat for metaethical realism and objectivity. In this paper I attempt to understand how it is that moral disagreement is supposed to present a problem for metaethical realism. I do this by going through several distinct (though often related) arguments from disagreement, carefully distinguishing between them, and critically evaluating their merits. My conclusions are rather skeptical: Some of the arguments I discuss fail rather clearly. Others supply with a challenge to realism, but (...) not one we have any reason to believe realism cannot address successfully. Others beg the question against the moral realist, and yet others raise serious objections to realism, but ones that—when carefully stated—can be seen not to be essentially related to moral disagreement. Arguments based on moral disagreement itself have almost no weight, I conclude, against moral realism. (shrink)

By the time of his death in 2003, Bernard Williams was one of the greatest philosophers of his generation. Ethics and the Limits of Philosophy is not only widely acknowledged to be his most important book, but also hailed a contemporary classic of moral philosophy. Presenting a sustained critique of moral theory from Kant onwards, Williams reorients ethical theory towards ‘truth, truthfulness and the meaning of an individual life’. He explores and reflects upon the most difficult problems in contemporary philosophy (...) and identifies new ideas about central issues such as relativism, objectivity and the possibility of ethical knowledge.

We can see a theft, hear a lie, and feel a stabbing. These are morally important perceptions. But are they also moral perceptions--distinctively moral responses? In this book, Robert Audi develops an original account of moral perceptions, shows how they figure in human experience, and argues that they provide moral knowledge. He offers a theory of perception as an informative representational relation to objects and events. He describes the experiential elements in perception, illustrates moral perception in relation to everyday observations, (...) and explains how moral perception justifies moral judgments and contributes to objectivity in ethics. -/- Moral perception does not occur in isolation. Intuition and emotion may facilitate it, influence it, and be elicited by it. Audi explores the nature and variety of intuitions and their relation to both moral perception and emotion, providing the broadest and most refined statement to date of his widely discussed intuitionist view in ethics. He also distinguishes several kinds of moral disagreement and assesses the challenge it poses for ethical objectivism. -/- Philosophically argued but interdisciplinary in scope and interest, Moral Perception advances our understanding of central problems in ethics, moral psychology, epistemology, and the theory of the emotions.

We often find that beliefs we hold are in conflict with the beliefs of epistemic peers, individuals who are just as intelligent, just as well-informed, and just as scrupulous in forming their beliefs as we are. Is it permissible to maintain our beliefs in the face of such disagreement? It is argued here that continued belief in these circumstances is not epistemically permissible, and that this has striking consequences for the practice of philosophy: we cannot reasonably hold on to our (...) philosophical views.

How much should your confidence in your beliefs be shaken when you learn that others – perhaps ‘epistemic peers’ who seem as well-qualified as you are – hold beliefs contrary to yours? This article describes motivations that push different philosophers towards opposite answers to this question. It identifies a key theoretical principle that divides current writers on the epistemology of disagreement. It then examines arguments bearing on that principle, and on the wider issue. It ends by describing some outstanding questions (...) that thinking about this issue raises. (shrink)

The human brain has some capabilities that the brains of other animals lack. It is to these distinctive capabilities that our species owes its dominant position. Other animals have stronger muscles or sharper claws, but we have cleverer brains. If machine brains one day come to surpass human brains in general intelligence, then this new superintelligence could become very powerful. As the fate of the gorillas now depends more on us humans than on the gorillas themselves, so the fate of (...) our species then would come to depend on the actions of the machine superintelligence. But we have one advantage: we get to make the first move. Will it be possible to construct a seed AI or otherwise to engineer initial conditions so as to make an intelligence explosion survivable? How could one achieve a controlled detonation? To get closer to an answer to this question, we must make our way through a fascinating landscape of topics and considerations. Read the book and learn about oracles, genies, singletons; about boxing methods, tripwires, and mind crime; about humanity's cosmic endowment and differential technological development; indirect normativity, instrumental convergence, whole brain emulation and technology couplings; Malthusian economics and dystopian evolution; artificial intelligence, and biological cognitive enhancement, and collective intelligence.

Jonathan Dancy thinks that there are irreducibly normative properties. Frank Jackson has given a well-known argument against this view, and I have elsewhere defended this argument against many objections, including one made by Dancy. But Dancy remains unconvinced. In this chapter, I hope to convince him.

My aim in this essay is largely defensive. I aim to discuss some problems for moral error theory and to offer plausible solutions. A full positive defense of moral error theory would require substantial investigations of rival metaethical views, but that is beyond the scope of this essay. I will, however, try to motivate moral error theory and to clarify its commitments. Moral error theorists typically accept two claims – one conceptual and one ontological – about moral facts. The conceptual (...) claim is that moral facts are or entail facts about categorical reasons (and correspondingly that moral claims are or entail claims about categorical reasons); the ontological claim is that there are no categorical reasons – and consequently no moral facts – in reality. I accept this version of moral error theory and I try to unpack what it amounts to in Section 2.1 In the course of doing so I consider two preliminary objections: that moral error theory is (probably) false because its implications are intuitively unacceptable (what I call the Moorean objection) and that the general motivation for moral error theory is self-undermining in that it rests on a hidden appeal to norms. The above characterization seems to entail the standard formulation of moral error theory, according to which first-order moral claims are uniformly false. Critics have argued that the standard formulation is incoherent since – by the law of excluded middle – the negation of a false claim is true. Hence if ‘Torture is wrong’ is false, ‘Torture is not wrong’ is true. Contrary to what moral error theorists contend, then, moral error theory seems to carry first-order moral implications that by the theory’s own lights are uniformly false. In Section 3 I suggest a formulation that is consistent with the standard formulation of moral error theory, free of first-order moral implications, and subject to no logical difficulties. In Section 4 I consider and rebut Stephen Finlay’s recent attack on moral error theory. According to Finlay the conceptual claim is false because all moral claims – and indeed all normative claims – are, or should be understood as, relativized to some moral standard or system of ends. Moral error theorists thus attribute to ordinary speakers an error that simply isn’t there. I argue that Finlay’s view has some very implausible implications and that it does not avoid commitment to various forms of error theory. This becomes especially clear when we focus on fundamental moral claims. In Section 5 I consider the worry that error theorists’ rejection of categorical reasons proves too much; in particular, the worry that error theorists’ qualms about categorical reasons apply equally to claims about hypothetical reasons, that is, claims to the effect that there is reason to take the means to one’s ends. In my view error theorists such as Mackie and Joyce have failed to pay due consideration to this problem. What the challenge establishes, I submit, is that error theorists cannot just take for granted that hypothetical reasons are metaphysically unproblematic; they must offer an account of hypothetical reasons that shows that they are. I argue that the only plausible account available to error theorists is one according to which claims about hypothetical reasons reduce to non-normative claims about relations between means and ends.

It has often been suggested that people's ordinary understanding of morality involves a belief in objective moral truths and a rejection of moral relativism. The results of six studies call this claim into question. Participants did offer apparently objectivist moral intuitions when considering individuals from their own culture, but they offered increasingly relativist intuitions considering individuals from increasingly different cultures or ways of life. The authors hypothesize that people do not have a fixed commitment to moral objectivism but instead tend (...) to adopt different views depending on the degree to which they consider radically different perspectives on moral questions.

There is a debate in normative ethics about whether or not our moral obligations depend solely on either our evidence concerning, or our beliefs about, the world. Subjectivists maintain that they do and objectivists maintain that they do not. I shall offer some arguments in support of objectivism and respond to the strongest argument for subjectivism. I shall also briefly consider the significance of my discussion to the debate over whether one’s future voluntary actions are relevant to one’s current moral (...) obligations. (shrink)

Conciliatory theories of disagreement face a revenge problem; they cannot be coherently believed by one who thinks they have peers who are not conciliationists. I argue that this is a deep problem for conciliationism.

Statements about a person's good slip into and out of our ordinary discourse about the world with nary a ripple. Such statements are objects of belief and assertion, they obey the rules of logic, and they are often defended by evidence and argument. They even participate in common-sense explanations, as when we say of some person that he has been less subject to wild swings of enthusiasm and disappointment now that, with experience, he has gained a clearer idea of what (...) is good for him. Statements about a person's good present themselves as being about something with respect to which our beliefs can be true or false, warranted or unwarranted. Let us speak of these features as the descriptive side of discourse about a person's good. (shrink)

This book defends a form of ethical intuitionism, according to which (i) there are objective moral truths; (ii) we know some of these truths through a kind of immediate, intellectual awareness, or "intuition"; and (iii) our knowledge of moral truths gives us reasons for action independent of our desires. The author rebuts all the major objections to this theory and shows that the alternative theories about the nature of ethics all face grave difficulties.

Some philosophers think that normative properties are identical to descriptive properties. In this paper, I argue that this entails that it is possible to say which descriptive properties normative properties are identical to. I argue that Frank Jackson's argument to show that this is possible fails, and that the objections to this argument show that it is impossible to say which descriptive properties normative properties are identical to. I conclude that normative properties are not identical to descriptive properties. I then (...) show that if we combine this conclusion with the conclusion of a different argument that Jackson has given to show that there are no irreducibly normative properties, it follows that there are no normative properties at all. (shrink)

My conclusion will be that, more often than we might have thought, suspension of judgment is the epistemically proper attitude. It follows that in such cases we lack reasonable belief and so, at least on standard conceptions, knowledge. This is a kind of contingent real-world skepticism that has not received the attention it deserves. I hope that this paper will help to bring this issue to life.

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.

Long claimed to be the dominant conception of practical reason, the Humean theory that reasons for action are instrumental, or explained by desires, is the basis for a range of worries about the objective prescriptivity of morality. As a result, it has come under intense attack in recent decades. A wide variety of arguments have been advanced which purport to show that it is false, or surprisingly, even that it is incoherent. Slaves of the Passions aims to set the record (...) straight, by advancing a version of the Humean theory of reasons which withstands this sophisticated array of objections. Schroeder defends a radical new view which, if correct, means that the commitments of the Humean theory have been widely misunderstood. Along the way, he raises and addresses questions about the fundamental structure of reasons, the nature of normative explanations, the aims of and challenges facing reductive views in metaethics, the weight of reasons, the nature of desire, moral epistemology, and most importantly, the relationship between agent-relational and agent-neutral reasons for action.

In this much-anticipated book, Jonathan Dancy offers the only available full-scale treatment of particularism in ethics, a view with which he has been associated for twenty years. Dancy now presents particularism as the view that the possibility of moral thought and judgement does not in any way depend on an adequate supply of principles. He grounds this claim on a form of reasons-holism, holding that what is a reason in one case need not be any reason in another, and maintaining (...) that moral reasons are no different in this respect from others. Ethics Without Principles offers detailed treatment and criticism of opposing positions of all sorts, with useful summaries. It also contains three chapters on the nature of what Dancy calls 'contributory' reasons, which, though the topic of much interest at the moment, are not often discussed in anything like the detail given here. And it offers a distinctive form of value-holism to go with the holism of reasons. As Dancy's definitive statement on particularism, the book will be required reading for all those working on moral philosophy and ethical theory. (shrink)

Knowledge and its Limits presents a systematic new conception of knowledge as a kind of mental stage sensitive to the knower's environment. It makes a major contribution to the debate between externalist and internalist philosophies of mind, and breaks radically with the epistemological tradition of analyzing knowledge in terms of true belief. The theory casts new light on such philosophical problems as scepticism, evidence, probability and assertion, realism and anti-realism, and the limits of what can be known. The arguments are (...) illustrated by rigorous models based on epistemic logic and probability theory. The result is a new way of doing epistemology and a notable contribution to the philosophy of mind. (shrink)

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.

In this book, T. M. Scanlon offers new answers to these questions, as they apply to the central part of morality that concerns what we owe to each other.

This book introduces the reader to ethics by examining a current and important debate. During the last fifty years the orthodox position in ethics has been a broadly non-cognitivist one: since there are no moral facts, moral remarks are best understood, not as attempting to describe the world, but as having some other function - such as expressing the attitudes or preferences of the speaker. In recent years this position has been increasingly challenged by moral realists who maintain that there (...) are moral facts; there is a truth of the matter in ethics, which is independent of our views, and which we seek to discover. Unfortunately much of this interesting debate found in the work of McDowell, Wiggins, Putnam, Blackburn and others is not easily accessible to undergraduates. McNaughton presents many of the major issues in ethics by way of a clear exposition of both sides of this argument and assumes no prior knowledge of philosophy. Topics discussed include: moral observation, moral motivation, amoralism and wickedness, moral weakness, cultural relativism and utilitarianism. The book concludes that a convincing case can be made out for a radical form of moral realism in which moral virtue is found, not in the following of correct moral principles, but rather in the development of moral sensitivity. Moral Vision is a clear and engaged introduction to an important, and often troubling, debate. (shrink)

The phenomenon of persistent ethical disagreement is often cited in connection with the question of whether there is any ‘‘absolute’’ morality, or whether, instead, morality is in some sense merely ‘‘a matter of personal opinion’’. Citing disagreement, many people who hold strong views about controversial issues such as the permissibility of abortion, eating meat, or the death penalty deny that these views are anything more than ‘‘personal beliefs’’. But while there might be inconsistencies lurking in this position, it is not (...) obviously at fault for according the facts about disagreement some epistemic weight. This paper addresses the question of whether and to what extent moral disagreement undermines moral knowledge. The most familiar arguments from disagreement in the literature purport to establish conclusions about the metaphysics of morality: that there are no moral facts, or that there are no moral properties, or that the moral facts are relative rather than absolute. Of course, the conclusions of some such metaphysical arguments might be perfectly consistent with the existence of considerable moral knowledge. For example, even if there is some successful argument from disagreement to the conclusion that moral facts are relative rather than absolute, this might very well be consistent with our having just as much moral knowledge as we..

My aim in this paper is to develop and defend a novel answer to a question that has recently generated a considerable amount of controversy. The question concerns the normative significance of peer disagreement. Suppose that you and I have been exposed to the same evidence and arguments that bear on some proposition: there is no relevant consideration which is available to you but not to me, or vice versa. For the sake of concreteness, we might picture.

In this article, I will defend the so-called buck-passing theory of value. According to this theory, claims about the value of an object refer to the reason-providing properties of the object. The concept of value can thus be analyzed in terms of reasons and the properties of objects that provide them for us. Reasons in this context are considerations that count in favour of certain attitudes. There are four other possibilities of how the connection between reasons and value might be (...) formulated. For example, we can claim that value is a property that provides us with reasons to choose an option that has this property. I argue that none of these four other options can ultimately be defended, and therefore the buck-passing account is the one we ought to accept as the correct one. The case for the buck-passing account becomes even stronger, when we examine the weak points of the most pressing criticism against this account thus far. (shrink)

My thesis is that morality arises when a group of people reach an implicit agreement or come to a tacit understanding about their relations with one another. Part of what I mean by this is that moral judgments - or, rather, an important class of them - make sense only in relation to and with reference to one or another such agreement or understanding. This is vague, and I shall try to make it more precise in what follows. But it (...) should be clear that I intend to argue for a version of what has been called moral relativism. (shrink)

How should you take into account the opinions of an advisor? When you completely defer to the advisor's judgment, then you should treat the advisor as a guru. Roughly, that means you should believe what you expect she would believe, if supplied with your extra evidence. When the advisor is your own future self, the resulting principle amounts to a version of the Reflection Principle---a version amended to handle cases of information loss. When you count an advisor as an epistemic (...) peer, you should give her conclusions the same weight as your own. Denying that view---call it the ``equal weight view''---leads to absurdity: the absurdity that you could reasonably come to believe yourself to be an epistemic superior to an advisor simply by noting cases of disagreement with her, and taking it that she made most of the mistakes. Accepting the view seems to lead to another absurdity: that one should suspend judgment about everything that one's smart and well-informed friends disagree on, which means suspending judgment about almost everything interesting. But despite appearances, the equal weight view does not have this absurd consequence. Furthermore, the view can be generalized to handle cases involving not just epistemic peers, but also epistemic superiors and inferiors. (shrink)

This essay juxtaposes the position in metaethics defended, expressivism with quasirealistic trimmings, with the ancient problem of relativism. It argues that, perhaps surprisingly, there is less of a problem of normative truth on this approach than on others. Because ethics is not in the business of representing aspects of the world, there is no way to argue for a plurality of moral truths, simply from the existence of a plurality of moral opinions. The essay also argues that other approaches, which (...) superficially seem better adapted to defending robust and substantive conceptions of moral truth, in fact face more danger from the threat of relativism. This is particularly so in the case of 'secondary quality' or 'response-dependent' approaches, but also in the case of certain kinds of constructivism. (shrink)

Frank Jackson champions the cause of conceptual analysis as central to philosophical inquiry. In recent years conceptual analysis has been undervalued and widely misunderstood, suggests Jackson. He argues that such analysis is mistakenly clouded in mystery, preventing a whole range of important questions from being productively addressed. He anchors his argument in discussions of specific philosophical issues, starting with the metaphysical doctrine of physicalism and moving on, via free will, meaning, personal identity, motion, and change, to ethics and the philosophy (...) of color. In this way the book not only offers a methodological program for philosophy, but also casts new light on some much-debated problems and their interrelations. (shrink)

Objectivists about obligation hold that obligations are determined by all of the normatively relevant facts. Perspectivalists, on the other hand, hold that only facts within one’s perspective can determine what we are obligated to do. This chapter argues for a perspectivalist view. It argues that what you are obligated to do is determined by the normative reasons you possess. This view is anchored in the thought that our obligations have to be action-guiding in a certain sense—we have to be able (...) to act for the reasons that obligate us. The chapter argues that we have this ability—the ability to act for the right reasons—only if we possess those reasons. Thus, objectivism is false. The second half of the chapter argues that problems having to do with new information do not plague the particular perspectival view presented. (shrink)

This is a short precis of my 2014 book Confusion of Tongues: A Theory of Normative Language, accompanying my Reply to Worsnip, Dowell, and Koehn in the same volume.

Many philosophers think that moral objectivism is supported by stable features of moral discourse and thinking. When engaged in moral reasoning and discourse, people behave ‘as if’ objectivism were correct, and the seemingly most straightforward way of making sense of this is to assume that objectivism is correct; this is how we think that such behavior is explained in paradigmatically objectivist domains. By comparison, relativist, error-theoretic or non-cognitivist accounts of this behavior seem contrived and ad hoc. After explaining why this (...) argument should be taken seriously (recent arguments notwithstanding), I argue that it is nevertheless undermined by considerations of moral disagreement. Even if the metaphysical, epistemic and semantic commitments of objectivism provide little or no evidence against it, and even if the alternative explanations of ‘objectivist’ traits of moral discourse and thinking are speculative or contrived, objectivism is itself incapable of making straightforward sense of these traits. Deep and widespread moral disagreement or, rather, the mere appearance of such disagreement, strongly suggests that the explanations operative in paradigmatically objective discourse fail to carry over to the moral case. Since objectivism, no less than relativism, non-cognitivism and error-theories, needs non-trivial explanations of why we behave ‘as if’ objectivism were correct, such behavior does not presently provide reason to accept objectivism.
