Moral metasemantic theories explain how our moral thought and talk are about certain properties. Given the connection between what our moral terms are about and which moral claims are true, it might be thought that metasemantic theorising can justify first-order ethical conclusions, thus providing a novel way of doing moral epistemology. In this paper, we spell out one kind of argument from metasemantic theories to normative ethical conclusions, and argue that it fails to transmit justification from premises to conclusion. We (...) give three reasons for this transmission failure, which together pose a serious challenge to such metasemantic arguments. (shrink)

Virtue ethics has many times been suggested as a promising recipe for the construction of artificial moral agents due to its emphasis on moral character and learning. However, given the complex nature of the theory, hardly any work has de facto attempted to implement the core tenets of virtue ethics in moral machines. The main goal of this paper is to demonstrate how virtue ethics can be taken all the way from theory to machine implementation. To achieve this goal, we (...) critically explore the possibilities and challenges for virtue ethics from a computational perspective. Drawing on previous conceptual and technical work, we outline a version of artificial virtue based on moral functionalism, connectionist bottom–up learning, and eudaimonic reward. We then describe how core features of the outlined theory can be interpreted in terms of functionality, which in turn informs the design of components necessary for virtuous cognition. Finally, we present a comprehensive framework for the technical development of artificial virtuous agents and discuss how they can be implemented in moral environments. (shrink)

Although virtue ethics has repeatedly been proposed as a suitable framework for the development of artificial moral agents, it has been proven difficult to approach from a computational perspective. In this work, we present the first technical implementation of artificial virtuous agents in moral simulations. First, we review previous conceptual and technical work in artificial virtue ethics and describe a functionalistic path to AVAs based on dispositional virtues, bottom-up learning, and top-down eudaimonic reward. We then provide the details of a (...) technical implementation in a moral simulation based on a tragedy of the commons scenario. The experimental results show how the AVAs learn to tackle cooperation problems while exhibiting core features of their theoretical counterpart, including moral character, dispositional virtues, learning from experience, and the pursuit of eudaimonia. Ultimately, we argue that virtue ethics provides a compelling path toward morally excellent machines and that our work provides an important starting point for such endeavors. (shrink)

This chapter uses the distinction between speculative and analytic philosophy as a background against which to present the summaries of the articles on the nature of philosophy by Mary Whiton Calkins, Dorothy Walsh and Marjorie Glicksman. Calkins and Walsh (in her first contribution) examine the relationship between philosophy and metaphysics: Calkins identifies philosophy with speculative metaphysics while Walsh argues that any ethical theory requires some underlying speculative metaphysics. In Walsh’s second contribution, she further argues that philosophical language rightly is characteristically (...) different from the languages of science, logic and poetry. Glicksman, finally, addresses the question how to deal with the multiplicity of views concerning the nature of philosophy. (shrink)

It is generally believed that moral reductionism is immune from notorious problems in moral metaphysics and epistemology, such as the problem of moral explanation – it is at least on this dimension that moral reductionism scores better than moral anti- reductionism. However, in this article I reject this popular view. First, I argue that moral reductionism fails to help vindicate the explanatory efficacy of moral properties because the reductionist solution is either circular or otiose. Second, I attempt to show that (...) a successful vindication, if any, of moral explanation requires moral-descriptive irreducibility. My discussion thus raises an explanatory challenge to moral reductionism. (shrink)

This article argues that the best way to pursue systematic normative ethical theorizing involves metaethical enquiry. My argument builds upon two central claims. First, I argue that plausible metaethical accounts can have implications that can help to resolve the methodological controversies facing normative ethics. Second, I argue that metaethical research is at least roughly as well supported as normative ethical research. I conclude by examining the implications of my thesis. Inter alia, it shows that the common practice of engaging in (...) systematic normative theorizing uninformed by metaethical commitments offers a significant and troubling hostage to metaethical fortune.

The advocates of moral perception claim that we can literally perceive moral properties such as goodness and badness. One of the objections to the thesis of moral perception is that since we are not able to causally interact with moral properties and these properties are causally inert, thus they do not fall into the scope of our perception. In reply, the advocates propose different solutions: 1) moral properties supervene on natural properties, 2) moral properties are secondary natural properties, and 3) (...) moral properties are non-secondary natural properties. Each of these proposals aims to attack a different premise of the objection. In this paper, I am going to propose the thesis that assuming that moral properties are grounded in natural properties, Wilsonian grounding can be a new reply to this objection. I will try to explain how Alastair Wilson’s account of grounding, in addition to a grounding thesis about the relation between moral and natural properties, can prevent accidence without setting moral properties aside from perceptual scope.

Ramsification is a well-known method of defining theoretical terms that figures centrally in a wide range of debates in metaphysics. Prior's puzzle is the puzzle of why, given the assumption that that-clauses denote propositions, substitution of "the proposition that P" for "that P" within the complements of many propositional attitude verbs sometimes fails to preserve truth, and other times fails to preserve grammaticality. On the surface, Ramsification and Prior's puzzle appear to have little to do with each other. But Prior's (...) puzzle is much more general than is ordinarily appreciated, and Ramsification requires a solution to the generalized form of Prior's puzzle. Without such a solution, a wide range of theories will either fail to imply their Ramsey sentences, or have Ramsey sentences that are ill-formed. As a consequence, definitions of theoretical terms given using the Ramsey sentence will be either incorrect or nonsensical. I present a partial solution to the puzzle that requires making use of a neo-Davidsonian language for scientific theorizing, but the would-be Ramsifier still faces serious challenges. (shrink)

Our project in this essay is to showcase nonnaturalistic moral realism’s resources for responding to metaphysical and epistemological objections by taking the view in some new directions. The central thesis we will argue for is that there is a battery of substantive moral propositions that are also nonnaturalistic conceptual truths. We call these propositions the moral fixed points. We will argue that they must find a place in any system of moral norms that applies to beings like us, in worlds (...) similar to our own. By committing themselves to true propositions of these sorts, nonnaturalists can fashion a view that is highly attractive in its own right, and resistant to the most prominent objections that have been pressed against it.

The central purpose of this essay is to consider some of the more prominent reasons why realists have rejected the Humean theory of motivation. I shall argue that these reasons are not persuasive, and that there is nothing about being a moral realist that should make us suspicious of Humeanism.

Cornell realists maintain that irreducible moral properties have earned a place in our ontology in virtue of the indispensable role they play in a variety of explanations. These explanations can be divided into two groups: those that employ thin ethical concepts and those that employ thick ethical concepts. Recent work on thick concepts suggests that they are not inherently evaluative in their meaning. If correct, this creates problems for the moral explanations of Cornell realists, since the most persuasive moral explanations (...) are those that employ thick concepts. If thick concepts are not inherently evaluative, then the most plausible explanations on offer cannot support Cornell realism. Moral explanations employing thin concepts, however, are too flimsy to support the view. Unless proponents can develop a compelling story about thick concepts or thin explanations, Cornell realism is in trouble. (shrink)

Deferred internalists accept that sometimes, agents can form genuine normative judgments without any accompanying motivation. However, they propose that these judgments can only exist when they are embedded within psychologies or communities in which judgment and motivation typically align. In this paper, I sketch a version of externalism that challenges the interpretation of key evidence claimed by deferred internalists. According to this account, there is a robust but contingent connection between judgment and motivation that is explained by the structure of (...) the neurocognitive apparatus we happen to employ in evaluative thought. This proposal allows that all of our judgments lacking accompanying motivation are contingently parasitic on judgments that are accompanied by motivation. It also suggests that it is not possible to create communities of _beings like us_ whose judgments and motivation radically come apart. These results undermine current strategies for supporting deferred internalism. Proponents will need to find support elsewhere. (shrink)

Ethics and mathematics have long invited comparisons. On the one hand, both ethical and mathematical propositions can appear to be knowable a priori, if knowable at all. On the other hand, mathematical propositions seem to admit of proof, and to enter into empirical scientific theories, in a way that ethical propositions do not. In this article, I discuss apparent similarities and differences between ethical (i.e., moral) and mathematical knowledge, realistically construed -- i.e., construed as independent of human mind and languages. (...) I argue that some are are merely apparent, while others are of little consequence. There is a difference between the cases. But it is not an epistemological difference per se. The difference, surprisingly, is that ethical knowledge, if it is practical, cannot fail to be objective in a way that mathematical knowledge can. One upshot of the discussion is radicalization of Moore’s Open Question Argument. Another is that the concepts of realism and objectivity, which are widely identified, are actually in tension.

There is an idea, going back to Aristotle, that reasons for action can be understood on a parallel with reasons for belief. Not surprisingly, the idea has almost always led to some form of inferentialism about reasons for action. In this paper I argue that reasons for action can be understood on a parallel with reasons for belief, but that this requires abandoning inferentialism about reasons for action. This result will be thought paradoxical. It is generally assumed that if there (...) is to be a useful parallel, there must be some such thing as a practical inference. As we shall see, that assumption tends to block the fruitful exploration of the real parallel. On the view I shall defend, the practical analogue of an ordinary inference is not an inference, but something I shall call a practical step. Nevertheless, the practical step will do, for a theory of reasons for action, what ordinary inference does for an inferentialist theory of reasons for belief. The result is a general characterization of reasons, practical and theoretical, in terms of the correctness conditions of the relevant sorts of step. (shrink)

This article sketches the main features of traditional philosophical models of evidence, indicating idealizations in such models that it regards as doing more harm than good. It then proceeds to elaborate on an alternative model of evidence that is functionalist, complex, dynamic, and contextual, a view the author calls dynamic evidential functionalism (DEF). This alternative builds on insights from philosophy of scientific practice, Kuhnian philosophy of science, pragmatist epistemology, philosophy of experimentation, and functionalist philosophy of mind. Along the way, the (...) article raises concerns about the total evidence condition, requirements of certainty or incorrigibility on evidence, and accounts that restrict the type of things that can serve as evidence (to, for example, sense data, facts about particulars). DEF can also help us see the special value of novel predictions and experiments as evidence, as well as help us think about how to critically evaluate the putative evidence to determine whether it is evidence.

that there is something rationally or conceptually defective in judging that an act is right without being in any way motivated towards it—is one which has tended to lead either to error theories of ethics on the one hand, or acceptance of the truth of internalism on the other. This paper argues that it does play a kind of subject-setting role, but that our responses to cases can be rationalised without requiring that internalism is true for ethical realism to be (...) vindicated. Instead what is required is that something like internalism be believed to be true. The widespreadness of the internalist intuition is part of what makes it the case that some actions are right and others wrong. Of course these beliefs might be false—as the present author holds—consistent with ethical realism, just so long as they are widely held, and whatever else it takes to vindicate realism is the case. In such a situation, widespread false belief would be part of what makes it so that some acts are right, and others wrong. (shrink)

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.

I argue—contra moderate grounding pluralists such as Kit Fine and more extreme grounding pluralists such as Jessica Wilson—that there is fundamentally only one grounding/in-virtue-of relation. I also argue that this single relation is indispensable for normative theorizing—that we can’t make sense of, for example, the debate over consequentialism without it. It follows from what I argue that there is no metaethically-pure normative ethics.

This paper considers normative naturalism, understood as the view that (i) normative sentences are descriptive of the way things are, and (ii) their truth/falsity does not require ontology beyond the ontology of the natural world. Assuming (i) for the sake of argument, I here show that (ii) is false not only as applied to ethics, but more generally as applied to practical and epistemic normativity across the board. The argument is a descendant of Moore's Open Question Argument and Hume's Is-Ought (...) Gap. It goes roughly as follows: to ensure that natural ontology suffices for normative truth, there must be semantically grounded entailments from the natural truths to the normative truths. There are none. So natural ontology does not suffice for normative truth. (shrink)

A posteriori Moral Naturalism posits a posteriorimoral/naturalistic identities. Versions of this view thatposit necessary identities purport to rely on theKripke/Putnam doctrine of scientific essentialism.Versions that posit only contingent identities requirethat moral terms are non-rigid designators. I argue thatmetaethics does not fall within the scope of scientificessentialism and that moral terms are not non-rigid designators.

A critical survey of various positions on the nature, use, possession, and analysis of normative concepts. We frame our treatment around G.E. Moore’s Open Question Argument, and the ways metaethicists have responded by departing from a Classical Theory of concepts. In addition to the Classical Theory, we discuss synthetic naturalism, noncognitivism (expressivist and inferentialist), prototype theory, network theory, and empirical linguistic approaches. Although written for a general philosophical audience, we attempt to provide a new perspective and highlight some underappreciated problems (...) about normative concepts. (shrink)

Methodological naturalism arises as a topic in metaethics in two ways. One is the issue of whether we should be methodological naturalists when doing our moral theorising, and another is whether we should take a naturalistic approach to metaethics itself. Interestingly, these can come apart, and some naturalist programs in metaethics justify a non-scientific approach to our moral theorising. This paper discusses the range of approaches that fall under the general umbrella of methodological naturalism, and how naturalists view the role (...) of science in ethics and metaethics. It discusses how naturalism interacts with the use of intuitions, using conceptual analysis, and reflective equilibrium methods. Finally, it discusses some ways using scientific investigation can make distinctive contributions to ethics and metaethics. (shrink)

Philosophy and Literature is an internationally renowned refereed journal founded by Denis Dutton at the University of Canterbury, Christchurch. It is now published by the Johns Hopkins University Press. Since its inception in 1976, Philosophy and Literature has been concerned with the relation between literary and philosophical studies, publishing articles on the philosophical interpretation of literature as well as the literary treatment of philosophy. Philosophy and Literature has sometimes been regarded as iconoclastic, in the sense that it repudiates academic pretensions, (...) insidious jargon and institutional vogue. Dutton, who remains the editor, still writes a regular column. A distinctive feature of Philosophy and Literature was the annual Bad Writing Contest, held from 1995–98, which sought to identify (and publish) the ‘most stylistically lamentable passages’ of academic prose, often to great amusement.

Recently, some philosophers have suggested that a form of robust realism about ethics, or normativity more generally, does not face a significant explanatory burden in metaphysics. I call this view metaphysically quietist normative realism . This paper argues that while this view can appear to constitute an attractive alternative to more traditional forms of normative realism, it cannot deliver on this promise. I examine Scanlon’s attempt to defend such a quietist realism, and argue that rather than silencing metaphysical questions about (...) normative reasons, his defense at best succeeds only in shifting the focus of metaphysical enquiry. I then set aside the details of Scanlon’s view, and argue on general grounds that that the quietist realist cannot finesse a crucial metanormative task: to explain the contrast between the correct normative system and alternative putatively normative standards.

I discuss Benacerraf's epistemological challenge for realism about areas like mathematics, metalogic, and modality, and describe the pluralist response to it. I explain why normative pluralism is peculiarly unsatisfactory, and use this explanation to formulate a radicalization of Moore's Open Question Argument. According to the argument, the facts -- even the normative facts -- fail to settle the practical questions at the center of our normative lives. One lesson is that the concepts of realism and objectivity, which are widely identified, (...) are actually in tension. (shrink)

The aim of this paper is to assess the relationship between anti-physicalist arguments in the philosophy of mind and anti-naturalist arguments in metaethics, and to show how the literature on the mind-body problem can inform metaethics. Among the questions we will consider are: (1) whether a moral parallel of the knowledge argument can be constructed to create trouble for naturalists, (2) the relationship between such a "Moral Knowledge Argument" and the familiar Open Question Argument, and (3) how naturalists can respond (...) to the Moral Twin Earth argument. We will give particular attention to recent arguments in the philosophy of mind that aim to show that anti-physicalist arguments can be defused by acknowledging a distinctive kind of conceptual dualism between the phenomenal and the physical. This tactic for evading anti-physicalist arguments has come to be known as the Phenomenal Concept Strategy. We will propose a metaethical version of this strategy, which we shall call the `Moral Concept Strategy'. We suggest that the Moral Concept Strategy offers the most promising way out of these anti-naturalist arguments, though significant challenges remain. (shrink)

According to the anti-Humean theory of motivation, it is possible to be motivated to act by reason alone. According to the Humean theory of motivation, this is impossible. The debate between these two theories remains as vigorous as ever (see for example Pettit 1987, Lewis 1988, Price 1989 and Smith 1994). In this paper I shall argue that the anti-Humean theory of motivation is incompatible with a number of prominent recent theories of content. I shall focus on causal or informational (...) theories of content (such as Dretske 1981, Fodor 1990 and Stalnaker 1984), and on verificationist theories of content (such as Dummett 1993, Putnam 1983 and Wright 1986), though in fact I believe that the same argument applies to several other theories of content as well.

This paper outlines a new approach to the task of giving an account of the meaning of moral statements: a sort of "conceptual role semantics", according to which the meaning of moral terms is given by their role in practical reasoning. This role is sufficient both to distinguish the meaning of any moral term from that of other terms, and to determine the property or relation (if any) that the term stands for. The paper ends by suggesting reasons for regarding (...) this "conceptual role semantics" approach as preferable to noncognitivism, the causal theory of reference, and noncircular conceptual analysis. (shrink)

Despite its many advantages as a metaethical theory, moral expressivism faces difficulties as a semantic theory of the meaning of moral claims, an issue underscored by the notorious Frege-Geach problem. I consider a distinct metaethical view, inferentialism, which like expressivism rejects a representational account of meaning, but unlike expressivism explains meaning in terms of inferential role instead of expressive function. Drawing on Michael Williams’ recent work on inferential theories of meaning, I argue that an appropriate understanding of the pragmatic role (...) of moral discourse—the facilitation of coordinated social behavior—suggests the kind of inferences we should expect terms with this function to license. I offer a sketch of the inferential roles the moral ‘ought’ plays, and argue that if we accept that the relevant inferential roles are meaning-constitutive, we will be in a position to solve the Frege-Geach problem. Such an inferentialist solution has advantages over those forwarded by expressivists such as Blackburn and Gibbard. First, it offers a more straightforward explanation of the meaning of moral terms. It also gives simple answers to at least two semantic worries that have vexed contemporary expressivists—the “problem of permissions” and the commitment to “mentalism”, both of which I argue are problems that don’t get traction with an inferentialist approach. I conclude by considering ways in which this approach can be expanded into a more robust semantic account. (shrink)

Moral platonism, the claim that moral entities are both objective and prescriptive, is generally thought to be a dead end. In an attempt to defend a moderate form of moral platonism or more precisely platonism about values, I first argue that several of the many versions of this doctrine are not committed to ontological extravagances. I then discuss an important objection due to John McDowell and developed by Michael Smith, according to which moral platonism is incoherent. I argue that objectivism (...) is compatible with the claim that certain ways of being aware of values, namely those involving emotions, are motivating. (shrink)

This paper considers the relation between philosophical discussions of, and social-scientific research into popular beliefs about, distributive justice. The first part sets out the differences and tensions between the two perspectives, identifying considerations which tend to lead adherents of each discipline to regard the other as irrelevant to its concerns. The second discusses four reasons why social scientists might benefit from philosophy: problems in identifying inconsistency, the fact that non-justice considerations might underlie distributive judgments, the way in which different principles (...) of justice can yield the same concrete distributive judgments, and the ambiguity of key terms. The third part distinguishes and evaluates three versions of the claim that normative theorising about justice can profit from empirical research into public opinion: that its findings are food for thought, that they amount to feasibility constraints, and that they are constitutive of normatively justified principles of justice. The view that popular opinion about justice has a strongly constitutive role to play in justifying principles of distributive justice stricto sensu is rejected, but it is argued that what the people think (and what they can reasonably be expected to come to think) on distributive matters can be an important factor for the political theorist to take into account, for reasons of legitimacy, or feasibility, or both.

Metaethical realists disagree about the nature of normative properties. Naturalists think that they are ordinary natural properties: causally efficacious, a posteriori knowable, and usable in the best explanations of natural and social sciences. Non-naturalist realists, in contrast, argue that they are sui generis: causally inert, a priori knowable and not a part of the subject matter of sciences. It has been assumed so far that naturalists can explain causally how the normative predicates manage to refer to normative properties, whereas non-naturalists (...) are unable to provide equally satisfactory metasemantic explanations. This article first describes how the previous non-naturalist accounts of reference fail to tell us how the normative predicates could have come to refer to the non-natural properties rather than to the natural ones. I will then use the so-called qua-problem to show how the causal theories of reference of naturalists also fail to fix the reference of normative predicates to unique natural properties. Finally, I will suggest that, just as naturalists need to rely on the non-causal mechanism of reference magnetism to solve the previous problem, non-naturalists, too, can rely on the very same idea to respond to the pressing metasemantic challenges that they face concerning reference. (shrink)

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)

The purpose of this paper is to defend G. E. Moore's open question argument, understood as an argument directed against analytic reductionism, the view that moral properties are analytically reducible to non-moral properties. In the first section I revise Moore's argument in order to make it as plausible and resistant against objections as possible. In the following two sections I develop the argument further and defend it against the most prominent objections raised against it. The conclusion of my line of (...) reasoning is that the open question argument offers the best explanation of our responses to the questions put in the argument, namely that analytic reductionism is mistaken.

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.

The Generalized Integration Challenge is the task of providing, for a given domain of discourse, a simultaneously acceptable metaphysics, epistemology and metasemantics and showing them to be so. In this paper, we focus on a metaethical position for which seems particularly acute: the brand of normative realism which takes normative properties to be mind-independent and causally inert. The problem is that these metaphysical commitments seem to make normative knowledge impossible. We suggest that bringing metasemantics into play can help to resolve (...) this puzzle. We propose an independently plausible metasemantic constraint on reference determination and show how it can provide a plausible response to for this brand of normative realism. (shrink)

Some philosophers hold that the neuroscience of action is, in practice or in principle, incapable of touching debates in action theory and moral psychology. The role of desires in action, the existence of basic actions, and the like are topics that must be sorted out by philosophers alone: at least at present, and perhaps by the very nature of the questions. This paper examines both philosophical and empirical arguments against the relevance of neuroscience to such questions and argues that neither (...) succeeds. In practice, there is already a stable body of findings from neuroanatomy and neurophysiology that warrants attention. And as a matter of principle, the ‘causal map’ of action production derivable from these findings requires the study of action theorists and moral psychologists because every such philosopher has commitments to the shape of this causal map: commitments that might be in conflict with reality.

This paper sketches a right-maker account of normative practical reasons along functionalist lines. The approach is contrasted with other similar accounts, in particular John Broome's analysis of reasons as explanations of oughts.

This paper is a response to Niklas Möller’s (Philosophical Studies, 2013) recent criticism of our relational (Jazz) model of meaning of thin evaluative terms. Möller’s criticism rests on a confusion about the role of coordinating intentions in Jazz. This paper clarifies what’s distinctive and controversial about the Jazz proposal and explains why Jazz, unlike traditional accounts of meaning, is not committed to analycities.

In Thinking How to Live, Allan Gibbard claims that expressivists can vindicate realism about moral discourse. This paper argues that Gibbard’s expressivism does not provide such a vindication.

This paper articulates two constraints on an acceptable account of meaning: (i) accessibility: sameness of meaning affords an immediate appearance of de jure co-reference, (ii) flexibility: sameness of meaning tolerates open-ended variation in speakers' substantive understanding of the reference. Traditional accounts of meaning have trouble simultaneously satisfying both constraints. I suggest that relationally individuated meanings provide a promising way of avoiding this tension. On relational accounts, we bootstrap our way to de jure co-reference: the subjective appearance of de jure co-reference (...) helps make it the case that two token representations really do co-refer.

What does it take to count as competent with the meaning of a thin evaluative predicate like 'is the right thing to do'? According to minimalists like Allan Gibbard and Ralph Wedgwood, competent speakers must simply use the predicate to express their own motivational states. According to analytic descriptivists like Frank Jackson, Philip Pettit and Christopher Peacocke, competent speakers must grasp a particular criterion for identifying the property picked out by the term. Both approaches face serious difficulties. We suggest that (...) these difficulties derive from a shared background assumption that competence conditions must be explained in terms of a determinate conceptual role. We propose a new way of characterizing competence with evaluative terms: what's required for competence is participation in a shared epistemic practice with a term. Our approach, we argue, better explains the nature of evaluative inquiry and the extent of disagreement about evaluative questions. (shrink)

Metaethical questions are typically held to be a priori , and therefore impervious to empirical evidence. Here I examine the metaethical claim that motive-internalism about belief , the position that moral beliefs are intrinsically motivating, is true. I argue that belief-internalists are faced with a dilemma. Either their formulation of internalism is so weak that it fails to be philosophically interesting, or it is a substantive claim but can be shown to be empirically false. I then provide evidence for the (...) falsity of substantive belief-internalism. I describe a group of brain-damaged patients who sustain impairment in their moral sensibility: although they have normal moral beliefs and make moral judgments, they are not inclined to act in accordance with those beliefs and judgments. Thus, I argue that they are walking counterexamples to the substantive internalist claim. In addition to constraining our conception of moral reasoning, this argument stands as an example of how empirical evidence can be relevantly brought to bear on a philosophical question typically viewed to be a priori.
