Metaethical non-analytical naturalism consists in the metaphysical thesis that normative properties are identical with or reducible to natural properties and the epistemological thesis that we cannot come to a complete understanding of the nature of normative properties via conceptual analysis alone. In On What Matters, Derek Parfit (2011) argues that non-analytical naturalism is either false or incoherent. In § 1, I show that his argument for this claim is unsuccessful, by showing that it rests on a tacit assumption about the (...) nature of normative thought that non-analytical naturalists need not accept. In § 2, I show that escaping Parfit’s argument in this way is no ad hoc maneuver; as I demonstrate, the idea that non-analytical naturalists can exploit to escape Parfit’s argument is a familiar one.

In contemporary metaethics, various versions of hybrid expressivism have been proposed according to which moral sentences express both non-cognitive attitudes and beliefs. One important advantage with such positions, its proponents argue, is that they, in contrast to pure expressivism, have a straightforward way of avoiding the Frege-Geach problem. In this paper, I provide a systematic examination of different versions of hybrid expressivism with particular regard to how they are assumed to evade this problem. The major conclusion is that none of (...) these views succeeds to provide both a fully satisfying interpretation of moral sentences and a convincing response to the Frege-Geach problem. I end by briefly considering alternative hybrid views that employ the notion of conventional or conversational implicature. (shrink)

Non-cognitivism is a variety of irrealism about ethics with a number of influential variants. Non-cognitivists agree with error theorists that there are no moral properties or moral facts. But rather than thinking that this makes moral statements false, noncognitivists claim that moral statements are not in the business of predicating properties or making statements which could be true or false in any substantial sense. Roughly put, noncognitivists think that moral statements have no truth conditions. Furthermore, according to non-cognitivists, when people (...) utter moral sentences they are not typically expressing states of mind which are beliefs or which are cognitive in the way that beliefs are. Rather they are expressing non-cognitive attitudes more similar to desires, approval or disapproval. Cognitivism is the denial of non-cognitivism. Thus it holds that moral statements do express beliefs and that they are apt for truth and falsity. But cognitivism need not be a species of realism since a cognitivist can be an error theorist and think all moral statements false. Still, moral realists are cognitivists insofar as they think moral statements are apt for truth and falsity and that many of them are in fact true. (shrink)

On its face, Hume's account of mental representation involves at least two elements. On the one hand, Hume often seems to write as though the representational properties of an idea are fixed solely by what it is a copy or image of. But, on the other, Hume's treatment of abstract ideas makes it clear that the representational properties of a Humean idea sometimes depend, not just on what it is copied from, but also on the manner in which the mind (...) associates it with other ideas. Past interpretations of Hume have tended to focus on one of these elements of his account to the neglect of the other. But no interpretation of this sort is likely to capture the role that both copying and association play within Hume's discussion. In what follows, I argue that the most plausible way of understanding Hume's discussion involves attributing to him a unified account of mental representation in which both of these elements play a central role. I close by discussing the manner in which reading Hume in this way would alter our understanding of the relationship between Hume's thought and contemporary philosophy of mind. (shrink)

Hybrid expressivists claim to solve the Frege-Geach problem by offloading the explanation of the logico-semantic properties of moral sentences onto beliefs that are components of hybrid states they express. We argue that this strategy is undermined by one of hybrid expressivism’s own commitments: that the truth of the belief-component is neither necessary nor sufficient for the truth of the hybrid state it composes. We articulate a new approach. Instead of explaining head-on what it is for, say, a pair of moral (...) sentences to be inconsistent, expressivists should “sidestep” and explain what it is _to think that_ a pair of moral sentences is inconsistent. To think so is to think they cannot both be true – a modal notion. Since expressivists have given accounts of such modals, we illustrate how sentences like ‘“lying is wrong” and “lying is not wrong” are inconsistent’ express sensible – and rationally compelling – states of mind. (shrink)

According to expressivists, normative language expresses desire‐like states of mind. According to noncognitivists, normative beliefs have a desire‐like functional role. What is the relation between these two doctrines? It is widely assumed that expressivism commits you to noncognitivism, and vice versa. This paper opposes that assumption. I advance a view that combines a noncognitivist psychology with a descriptivist semantics for normative language. While this might seem like an ungainly hybrid, I argue that it has important advantages over more familiar metaethical (...) positions. The noncognitivist aspect of the theory captures all of the explanatory benefits standardly associated with expressivism. At the same time, the descriptivist element allows us to avoid the semantic headaches for expressivism. (shrink)

Moral language displays a characteristic duality. On the one hand, moral claims seem to be similar to descriptive claims: To say that an act is right seems to be a matter of making an assertion, thus indicating that the speaker has a moral belief about which she can be correct or mistaken. On the other hand, moral claims seem to be different from descriptive claims: There is a sense in which, by claiming that an act is right, a speaker indicates (...) that she is inclined to perform the act, to want others to perform it, and to react with praise towards those who do it. Hybrid theories maintain that utterances of moral sentences have both a descriptive and a practical linguistic function. In this thesis, I investigate how a hybrid theory can best accommodate the descriptive and the practical aspects of moral language. I evaluate and criticize the way that existing hybrid theories have proposed to explain the duality of moral language. The main arguments against these views are that they either: fail to accommodate the way that the practical or attitudinal import of moral claims vary across different contexts and linguistic environments; or that they fail to show how the practical or attitudinal import is reliably inferred by interlocutors in virtue of general communicative principles. I develop and defend a new hybrid theory called ‘dynamic descriptivism’. This theory accommodates the duality of moral language by appeal to the way that moral utterances affect a dimension of communication which consists of the shared assumptions that interlocutors mutually assume to mutually accept. Moreover, I discuss a problem which has affected a wide range of theories of moral language – including existing hybrid theories – which is the problem of explaining what it is that interlocutors disagree about when they disagree about matters of morality. I argue that that dynamic descriptivism offers new resources for solving this problem. (shrink)

The following scenario seems possible: a community uses concepts that play the same role in guiding actions and shaping social life as our normative concepts, and yet refer to something else. As Eklund argues, this apparent possibility poses a problem for any normative realist who aspires to vindicate the thought that reality itself favors our ways of valuing and acting. How can realists make good on this idea, given that anything they might say in support of the privileged status of (...) our normative concepts can be mirrored by the imagined community? E.g., the realist might claim that using our concepts is what we ought to do if we are to describe normative facts correctly, but members of the other community can claim the same about their concepts, using their own concept of ought. A promising approach to this challenge is to try to rule out the possibility of alternative normative concepts, by arguing that any concepts that have the same normative role must share a reference as well. In this paper I argue that normative quasi-naturalism, a view that combines expressivism about normative discourse with a naturalist metaphysics of normativity, supports referential normativity and solves the problem of alternative normative concepts. (shrink)

According to ethical neo-expressivism, all declarative sentences, including those used to make ethical claims, have propositions as their semantic contents, and acts of making an ethical claim are properly said to express mental states, which (if motivational internalism is correct) are intimately connected to motivation. This raises two important questions: (i) The traditional reason for denying that ethical sentences express propositions is that these were thought to determine ways the world could be, so unless we provide an analysis of ethical (...) terms in terms of natural properties, are we not committed to the Moorean conclusion that ethical sentences describe sui generis “nonnatural” ways the world could be? (ii) If we reject the claim that motivational attitudes constitute any part of the semantics of ethical sentences, are we not committed to denying the intuition behind motivational internalism after all? This chapter argues for negative answers to both of these questions. (shrink)

Affective experiences motivate and rationalize behavior in virtue of feeling good or bad, or their valence. It has become popular to explain such phenomenal character with intentional content. Rejecting evaluativism and extending earlier imperativist accounts of pain, I argue that when experiences feel bad, they both represent things as being in a certain way and tell us to see to it that they will no longer be that way. Such commands have subjective authority by virtue of linking up with a (...) relevant background concern. The imperative content explains but doesn’t constitute world-directed motivation. It also rationalizes action indirectly, by giving rise to an affective seeming that represents the situation as calling for the authoritatively commanded behavior. One experience feels worse than another if its content tells us to bear a higher opportunity cost to comply with the command. Finally, experience-directed motivation is contingent on our being attitudinally (dis)pleased with the character of our experience. (shrink)

Normative cognition seems rather important, even ineliminable. Communities that lack normative concepts like SHOULD, IS A REASON TO, JUSTIFIES, etc. seem cognitively handicapped and communicatively muzzled. And yet a popular metaethic, normative naturalism, has a hard time accommodating this felt ineliminability. Here, I press the argument against normative naturalism, consider some replies on behalf of normative naturalists, and suggest that a version of sophisticated subjectivism does the best job preserving the importance and ineliminability of the special, normative way of thinking.

According to noncognitivism, normative beliefs are just desire-like attitudes. While noncognitivists have devoted great effort to explaining the nature of normative belief, they have said little about all of the other attitudes we take towards normative matters. Many of us desire to do the right thing. We sometimes wonder whether our conduct is morally permissible; we hope that it is, and occasionally fear that it is not. This gives rise to what Schroeder calls the 'Many Attitudes Problem': the problem of (...) developing a plausible noncognitivist account of the full range of attitudes that we take towards normative matters. This paper explores the problem and proposes a solution. (shrink)

Expressivists about normative thought and discourse traditionally deny that there are nondeflationary normative propositions. However, it has recently been suggested that expressivists might avoid a number of problems by providing a theory of normative propositions compatible with expressivism. This paper explores the prospects for developing an expressivist theory of propositions within the framework of cognitive act theories of propositions. First, I argue that the only extant expressivist theory of cognitive propositions—Michael Ridge's ‘ecumenical expressivist’ theory—fails to explain identity conditions for normative (...) propositions. Second, I argue that this failure motivates a general constraint—the ‘unity requirement’—that any expressivist theory of propositions must provide a unified nonrepresentational explanation of that in virtue of which propositional attitudes have the content that they have. Third, I argue that conceptual role accounts of content provide a promising framework in which to develop an expressivist theory of cognitive propositions. (shrink)

This paper develops a new challenge for moral noncognitivism. In brief, the challenge is this: Beliefs — both moral and non-moral — are epistemically evaluable, whereas desires are not. It is tempting to explain this difference in terms of differences in the functional roles of beliefs and desires. However, this explanation stands in tension with noncognitivism, which maintains that moral beliefs have a desire-like functional role. After critically reviewing some initial responses to the challenge, I suggest a solution, which involves (...) rethinking the functional relationship between desire and belief. (shrink)

People engage in pure moral inquiry whenever they inquire into the moral features of some act, agent, or state of affairs without inquiring into the non-moral features of that act, agent, or state of affairs. This chapter argues that ordinary people act rationally when they engage in pure moral inquiry, and so any adequate view in metaethics ought to be able to explain this fact. The Puzzle of Pure Moral Motivation is how to provide such an explanation. This chapter argues (...) that each of the standard views in metaethics has trouble providing such an explanation. Discussion of why reveals that a metaethical view can provide such an explanation only if it meets two constraints: it allows ordinary moral inquirers to know the essences of moral properties, and the essence of each moral property makes it rational to care for its own sake whether that property is instantiated. (shrink)

This paper offers a noncognitivist characterization of moral attitudes, according to which moral attitudes count as such because of their inclusion of moral concepts. Moral concepts are distinguished by their contribution to the functional roles of some of the attitudes in which they can occur. They have no particular functional role in other attitudes, and should instead be viewed as evolutionary spandrels. In order to make the counter-intuitive implications of the view more palatable, the paper ends with an account of (...) the evolution of normative judgments as exaptations of the cognitive structures that underlie beliefs. (shrink)

Non-cognitivists are known to face a problem in extending their account of straightforward predicative moral judgments to logically complex moral judgments. This paper presents a related problem concerning how non-cognitivists might extend their accounts of moral judgments to other kinds of moral attitudes, such as moral hopes and moral intuitions. Non-cognitivists must solve three separate challenges: they must explain the natures of these other attitudes, they must explain why they count as moral attitudes, and they must explain why the moral (...) attitudes are systematically correlated with ordinary propositional attitudes. After presenting the problem, this paper examines several contemporary theories with some initial promise for solving it, and argues that they are insufficient. (shrink)

This paper investigates whether different philosophers’ claims about “normativity” are about the same subject or (as recently argued by Derek Parfit) theorists who appear to disagree are really using the term with different meanings, in order to cast disambiguating light on the debates over at least the nature, existence, extension, and analyzability of normativity. While I suggest the term may be multiply ambiguous, I also find reasons for optimism about a common subject-matter for metanormative theory. This is supported partly by (...) sketching a special kind of hybrid view of normative judgment, perspectivism, that occupies a position between cognitivism and noncognitivism, naturalism and nonnaturalism, objectivism and subjectivism, making it more plausible that radically different metanormative theories could be about the same thing. I explore three main fissures: between (i) the “normativity” of language/thought versus that of facts and properties, (ii) abstract versus substantive senses, and (iii) formal versus robust senses. (shrink)

One important trend in the debate over expressivism and cognitivism is the emergence of ‘hybrid’ or ‘ecumenical’ theories. According to such theories, moral sentences express both beliefs, as cognitivism has it, and desire-like states, as expressivism has it. One may wonder, though, whether the hybrid move is as novel as its advocates seem to take it to be—or whether it simply leads us back to the conceptions of early expressivists, such as Charles Stevenson or Richard Hare. Michael Ridge has recently (...) argued that we ought not to see Hare as a hybrid expressivist because Hare’s approach allows for moral sentences that do not express any descriptive beliefs at all. Yet, Ridge’s reading has been challenged by John Eriksson, who even goes as far as to claim that modern hybrid expressivists should follow in Hare’s footsteps because it is Hare’s framework that actually provides a solution to the so-called ‘Frege-Geach problem’. In the present paper, I first want to show that we can defend Eriksson’s reading with regard to the official version of Hare’s theory. I will, secondly, argue that, in line with what we may take to be Ridge’s critical perspective on Hare, this official version faces serious difficulties, resulting from the possibility of unknown speaker standards. Thirdly, I will demonstrate that a modern reconstruction of Hare in terms of what I will refer to as ‘de dicto beliefs’, though in principle possible, will not allow us to solve the ‘Frege-Geach problem’.

This is a draft of a chapter for the Routledge Handbook of Metaethics, edited by David Plunkett and Tristram McPherson. I offer an overview of hybrid views in metaethics, with main focus on hybrid cognitivist views such as those defended by Daniel Boisvert and David Copp, and on hybrid expressivist views such as those defended by Michael Ridge and myself.

Normative naturalism holds that normative properties are identical with, or reducible to, natural properties. Various challenges to naturalism focus on whether it can make good on the idea that normative concepts can be used in systematically different ways and yet have the same reference in all contexts of use. In response to such challenges, some naturalists have proposed that questions about the reference of normative terms should be understood, at least in part, as normative questions that can be settled through (...) normative inquiry. In this paper I have two goals. First, I argue that these naturalist proposals do not yet allow for radical disagreement on normative matters, or at least do not explain how such disagreement is possible. Secondly, I argue that, in order to account for radical disagreement, naturalists should not only treat normative reference as a normative issue but also adopt a non-representationalist account of normative concepts, on which such concepts are individuated through their practical role. I illustrate this point by showing how a view that combines naturalism and expressivism about normative discourse can vindicate the elasticity of normative concepts, their referential stability, and the objectivity of normative truths.

This chapter identifies a novel family of metaethical theories that are non-descriptive and that aim to explain the action-guiding qualities of normative thought and language. The general strategy is to consider different relations language might bear to a given content, where we locate descriptivity (or lack of it) in these relations, rather than locating it in a theory that begins with the expression of states of mind, or locating it in a special kind of content that is not way-things-might-be content. (...) One such view is sketched, which posits two different content-fixing cognitive roles for bits of language. One role fixes a descriptive relation to content and another role fixes a non-descriptive relation to content. In addition to non-descriptivity and action guidance, the chapter briefly considers the appearance of mind-independent authoritative force, disagreement, and Frege–Geach concerns. (shrink)

Hybrid metaethical theories have significant promise; they would have important upshots if they were true. But they also face severe problems. The problems are severe enough to make many philosophers doubt that they could be true. My ambition is to show that the problems are just instances of a highly general problem: a problem about what are sometimes called ‘intensional anaphora'. I'll also show that any adequate explanation of intensional anaphora immediately solves all the problems for the hybrid theorist. We (...) should regard hybrid tools as among the most legitimate tools in our toolkit—at least when we use them properly. (shrink)

Expressivists have a problem with collectives. I initially illustrate the problem against the background of Allan Gibbard’s expressivist theory, where it is especially stark. I then argue that the problem generalizes. Gibbard’s account entails that judgments about what collective agents ought to do are contingency plans for what to do if one is in the circumstances facing the relevant collective agent. So, for example, my judgment that the United States ought not to have invaded Iraq is a contingency plan for (...) what to do if I find myself in the circumstances facing the United States on the eve of the Iraq war. I argue that, given plausible functionalist assumptions in the philosophy of mind expressivists would struggle to reject, such contingency plans are impossible for individual agents. Since normative judgments about collectives are possible, Gibbard’s theory is unacceptable. Having demonstrated the basic problem for Gibbard’s view, I then argue that the problem has a much wider scope. In particular, I argue that traditional forms of expressivism cannot simultaneously provide a plausible account of both agent-relative normative judgments and judgments about what collectives ought to do. Fortunately, all is not lost; hybrid or ‘ecumenical’ forms of expressivism can disarm the dilemma, or so I argue. I conclude by briefly sketching some further challenges ecumenical expressivism must overcome for its treatment of judgments about collectives to be fully satisfactory and indicate possible lines of argument to be pursued in future work on these challenges. (shrink)

Belief normativism is roughly the view that judgments about beliefs are normative judgments. Kathrin Glüer and Åsa Wikforss suggest that there are two ways one could defend this view: by appeal to what might be called ‘truth-norms’, or by appeal to what might be called ‘norms of rationality’ or ‘epistemic norms’. According to G&W, whichever way the normativist takes, she ends up being unable to account for the idea that the norms in question would guide belief formation. Plausibly, if belief (...) normativism were true, the relevant norms would have to offer such guidance. I argue that G&W’s case against belief normativism is not successful. In section 1, I defend the idea that truth-norms can guide belief formation indirectly via epistemic norms. In section 2, I outline an account of how the epistemic norms might guide belief. Interestingly, this account may involve a commitment to a certain kind of expressivist view concerning judgments about epistemic norms. (shrink)

A background assumption of much of 20th century and recent metaethics and moral psychology is that moral judgements either express beliefs rather than desire-like attitudes or express desire-like attitudes rather than beliefs. In a recent series of papers and а monograph, Michael Ridge seeks to reject this assumption, and thereby to steer the focus of metaethical debate away from the Frege-Geach problem. In particular, Ridge claims that we can formulate “ecumenical” views on which moral judgements express both beliefs and desire-like (...) attitudes, and that his own favoured metaethical position – Ecumenical Expressivism – can use the resources of cognitivism to provide a relatively straightforward solution to the Frege-Geach problem. In this paper we argue that Ridge’s Ecumenical Expressivist response to the Frege-Geach problem is inadequate and explore the consequences of this inadequacy for our outlook on moral psychology.

Quasi-realism aspires to preserve the intelligibility of the realist-sounding moral judgments of ordinary people. These judgments include ones of the form, “I believe that p, but I might be mistaken,” where “p” is some moral content. The orthodox quasi-realist strategy is to understand these in terms of the agent’s worrying that some improving change would lead one to aban-don the relevant moral belief. However, it is unclear whether this strate-gy generalizes to cases in which the agent takes their error to (...) be funda-mental in a sense articulated by Andy Egan. In an influential paper, Egan argues that it does not. Egan suggests that Blackburn’s approach is the only game in town for the quasi-realist when it comes to making sense of judgment of fallibility, and therefore concludes that Blackburn’s ina-bility to handle worries about fundamental moral error refutes quasi-realism tout court. Egan’s challenge has generated considerable discus-sion. However, in my view, we have not yet gotten to the heart of the matter. I argue that what is still needed is a fully general, quasi-realist-friendly theory of the nature of first-person judgments of fallibility, such that these judgments are demonstrably consistent with judging that the belief is stable in Egan’s sense. In this article, I develop and defend a fully general quasi-realist theory of such judgments, which meets this demand. With this theory in hand, I argue that Egan’s challenge can be met. Moreover, my discussion of how the challenge is best met provides an elegant diagnosis of where Egan’s argument against goes wrong. On my account, Egan’s argument equivocates at a key point between a “could” and a “would.”. (shrink)

I explore the prospects of capturing and explaining, within a non-cognitivist framework, the enkratic principle of rationality, according to which rationality requires of N that, if N believes that she herself ought to perform an action, φ, N intends to φ. Capturing this principle involves making sense of both the possibility and irrationality of akrasia – of failing to intend in accordance with one’s ought thought. In the first section, I argue that the existing non-cognitivist treatments of enkrasia/akrasia by Allan (...) Gibbard and Michael Ridge are not satisfying. In the second section, I propose that non-cognitivists should perhaps say roughly the following: to think that one ought to φ is to prefer φ-ing to the alternative courses of action, or to have a stronger desire to φ than to choose any alternative action. I outline an account of the strength of desire, which allows for the possibility of intending to act against one’s strongest desires, and makes it intelligible why rationality would nevertheless require that one’s strongest desires and intentions be aligned. This would allow the non-cognitivist to explain how akrasia is both possible and irrational. In the last section, I briefly suggest that this leaves non-cognitivists in a nice position in comparison to at least some of the competition, when it comes to capturing enkrasia. (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.

Quasi-realists aspire to accommodate core features of ordinary normative thought and discourse in an expressivist framework. One apparent such feature is that we can be more or less confident in our normative judgments—they vary in credence. Michael Smith has argued that quasi-realists cannot plausibly accommodate these distinctions simply because they understand normative judgments as desires, but desires lack the structure needed to distinguish these three features. Existing attempts to meet Smith’s challenge have accepted Smith’s presupposition that the way to meet (...) the challenge is to show that normative judgments have more structure than they initially seem to have. I argue that accepting this presupposition is accepting too much. The orthodox view of certitude, insofar as there is one, understands certitude very roughly in terms of counterfactual betting behaviour. Counterfactual betting behaviour, though, is not in any useful sense a structural feature of a given judgment. It is rather a more holistic feature of a given agent’s cognitive system. Insofar as it can meet the other challenges it faces, quasi-realism can characterize credences in terms of counterfactual betting behaviour and effectively say exactly what many realists will want to say about credences, thus meeting Smith’s challenge much more directly.

I then consider Worsnip’s comments on COT’s implications for normative ethical theory, and end by responding to Koehn’s challenges to the details of my (...) end-relational semantics and treatment of the notion of final value.

It is commonly claimed that reliance upon moral testimony is problematic in a way not common to reliance upon non-moral testimony. This chapter provides a new explanation of what the problem consists in—one that enjoys advantages over the most widely accepted explanation in the extant literature (in short, that moral deference undermines moral worth). The main theses of the chapter are as follows: (1) that many forms of normative deference beyond the moral are problematic (including aesthetic and prudential deference), (2) (...) that there is a common explanation of the problem with all of these forms of deference—an explanation that is based on the connection between the relevant judgments and desire-like attitudes, and (3) that this explanation is compatible with moral realism.

This paper develops and defends the view that substantively normative uses of words like “good”, “right” and “ought” are irresolvably indeterminate: any single case of application is like a borderline case for a vague or indeterminate term, in that the meaning-fixing facts, together with the non-linguistic facts, fail to determine a truth-value for the target sentence in context. Normative claims, like vague or indeterminate borderline claims, are not meaningless, though. By making them, the speaker communicates information about the precisifications that (...) s/he accepts. The analogy with vague/indeterminate language, I argue, lays out a new and interesting foundation for a subjectivist approach to normativity. (shrink)
