In this paper, I exploit the parallel between epistemic contextualism and metaethical speaker-relativism to argue that a promising way out of two of the primary problems facing contextualism is one already explored in some detail in the ethical case – viz. expressivism. The upshot is an argument for a form of epistemic expressivism modeled on a familiar form of ethical expressivism. This provides a new nondescriptivist option for understanding the meaning of knowledge attributions, which arguably better captures the normative nature (...) of epistemic discourse than descriptivist competitors like invariantism and contextualism.

My primary purpose in this paper is to sketch a theory of doxastic oughts that achieves a satisfying middle ground between the extremes of rejecting epistemic deontology because one thinks beliefs are not within our direct voluntary control and rejecting doxastic involuntarism because one thinks that some doxastic oughts must be true. The key will be appreciating the obvious fact that not all true oughts require direct voluntary control. I will construct my account as an attempt to surpass other accounts (...) (especially those due to Feldman and Kornblith) in this vein. The new idea (in a telegraphic slogan) is that doxastic oughts are what Sellars called “rules of criticism,” which are logically distinct from but also interestingly connected to “rules of action.” The distinction provides a way to understand the phrase ‘ought to believe’ which is consistent with both doxastic involuntarism and epistemic deontology; the connection provides a novel way to incorporate a believer’s epistemic community into our understanding of the scope of epistemic obligations.

It is a piece of philosophical commonsense that belief and knowledge are states. Some epistemologists reject this claim in hope of answering certain difficult questions about the normative evaluation of belief. I shall argue, however, that this move offends not only against philosophical commonsense but also against ordinary common sense, at least as far as this is manifested in the semantic content of the words we use to talk about belief and knowledge. I think it is relatively easily to show (...) with some linguistic tests that ordinary belief and knowledge attributions should be classified aspectually as state descriptions. Hence, the move some epistemologists to deny that belief and knowledge are states threatens to simply change the topic rather than open up answers to difficult questions in epistemology. I do not know fully how to answer the relevant questions about the normative evaluation of belief, but I pursue this critical point here in service of a positive proposal about the general framework in which they should be answered. In brief, the general framework is one which recognizes an important place for what I call state-norms, beside the action-norms which are more familiar from normative theory. And it locates the epistemic norms that apply to beliefs and are relevant for knowledge on the state-norm side of this divide. This turns out to be not only consistent with but indeed to underwrites the philosophical and ordinary commonsense that belief and knowledge are states. (shrink)

This paper explains three ways to develop a conceptual role view of meaning in metaethics. First, it suggests that there’s a way to combine inspiration from noncognitivism with a particular form of the conceptual role view to form a noncognitivist view with distinctive advantages over other noncognitivist views. Second, it suggests that there’s also a way to combine a strong commitment to cognitivism with a different form of the conceptual role view to form a version of cognitivism with distinctive advantages (...) over other cognitivist views. Finally, it suggests that there's another way to think of the conceptual role view in metaethics is as opening up the space for a third way, beyond cognitivism and noncognitivism. (shrink)

Theoretical reasoning aims to expand our knowledge of how the world is. Practical reasoning aims to expand our knowledge of how to behave in the world as we know it to be. Although this distinction between theoretical and practical reasoning is notoriously central to normative ethical theorizing, its significance has, I think, been underappreciated and misconstrued in the metaethical debate about realism. I suspect that this is the result of two aspects of that debate: (a) the realism debate has been (...) pursued (mostly) by investigating the appropriate semantic account of ethical statements, (b) all of the prominent semantic accounts on offer, both realist and irrealist, take representation rather than inference as their master concept, which leaves the distinction between ways of reasoning as explanatorily posterior to the distinction between representational and nonrepresentational items. Aspect (a) is not obviously beyond reproach—perhaps the reality of moral properties should be investigated by strictly metaphysical rather than semantic methods. However, for the purposes of this paper, I shall not reproach the methodological mindset that semanticizes the realism debate in metaethics. This is because it is by working within this mindset that I think we have best hope of correcting the mistake I see embodied in aspect (b) and gaining a fuller appreciation of the significance of the distinction between theoretical and practical reasoning to the realism debate. Thus, my overarching aim in this paper is to begin to explore what happens to that debate when we take inference rather than representation as our master concept in philosophical semantics. More specifically, I want to consider the fortunes of the most prominent form of irrealism—expressivism—and urge that a new form of this position, which takes the distinction between theoretical and practical reasoning (rather than the distinction between representational and nonrepresentational mental states) as basic, has the resources to address one of the main objections threatening contemporary versions of the view.

Ethical theorists often assume that the verb ?ought? means roughly ?has an obligation?; however, this assumption is belied by the diversity of ?flavours? of ought-sentences in English. A natural response is that ?ought? is ambiguous. However, this response is incompatible with the standard treatment of ?ought? by theoretical semanticists, who classify ?ought? as a member of the family of modal verbs, which are treated uniformly as operators. To many ethical theorists, however, this popular treatment in linguistics seems to elide an (...) important distinction between agential and non-agential ought-statements. The thought is that ?ought? must have at least two senses, one implicating agency and connected to obligations, and another covering other uses. In this paper, I pursue some resolution of this tension between semantic theory and ethical theory with respect to the meaning of ?ought?. To this end, I consider what I believe to be the most linguistically sophisticated argument for the view that the word ?ought? is ambiguous between agential and non-agential senses. This argument, due to Mark Schroeder, is instructive but based on a false claim about the syntax of agential ought-sentences?or so I attempt to show by first situating Schroeder's argument in its proper linguistic background and then discussing some syntactic evidence that he fails to appreciate. Then, I use the failure of this argument to motivate some more general reflections on how the standard treatment of ?ought? by theoretical semanticists might be refined in the light of the distinction important to ethical theory between agential and non-agential ought-statements, but also on how ethical theory might benefit from more careful study of the dominant treatment of modals as operators in theoretical semantics.

Epistemic expressivism is the application of a nexus of ideas, which is prominent in ethical theory (more specifically, metaethics), to parallel issues in epistemological theory (more specifically, metaepistemology). Here, in order to help those new to the debate come to grips with epistemic expressivism and recent discussions of it, I first briefly present this nexus of ideas as it occurs in ethical expressivism. Then, I explain why and how some philosophers have sought to extend it to a version of epistemic (...) expressivism. Finally, I consider a number of objections and replies with the aim of giving the reader the tools needed to begin to evaluate the promise and prospects of epistemic expressivism. (shrink)

Expressivist views of an area of discourse encourage us to ask not about the nature of the relevant kinds of values but rather about the nature of the relevant kind of evaluations. Their answer to the latter question typically claims some interesting disanalogy between those kinds of evaluations and descriptions of the world. It does so in hope of providing traction against naturalism-inspired ontological and epistemological worries threatening more ‘realist’ positions. This is a familiar position regarding ethical discourse; however, some (...) authors have recently defended a similar view regarding epistemic discourse. Others have argued that epistemic expressivism faces special problems, not necessarily attaching to expressivism about other areas. Their arguments differ in interesting ways, but the common strategy is an attempt to show that the very sort of meta-epistemological theorizing needed to articulate and establish epistemic expressivism involves the epistemic expressivist in some sort of internal incoherence or self-defeat. That is, they think that articulating or defending the position requires implicit commitment to the negation of one of the positions core tenets. This paper responds to those arguments on behalf of epistemic expressivism, suggesting that they each misunderstand what is crucial to epistemic expressivism. By responding to these arguments, we hope to achieve more clarity about what epistemic expressivism is and why one might want to endorse it in a meta-epistemology. (shrink)

The dominant route to nondescriptivist views of normative and evaluative language is through the expressivist idea that normative terms have distinctive expressive roles in conveying our attitudes. This paper explores an alternative route based on two ideas. First, a core normative term ‘ought’ is a modal operator; and second, modal operators play a distinctive nonrepresentational role in generating meanings for the statements in which they figure. I argue that this provides for an attractive alternative to expressivist forms of nondescriptivism about (...) normative language. In the final section of the paper, I explore ways it might be extended to evaluative language. (shrink)

On the assumption that genuinely normative demands concern things connected in some way to our agency, i.e. what we exercise in doing things with or for reasons, epistemologists face an important question: are there genuine epistemic norms governing belief, and if so where in the vicinity of belief are we to find the requisite cognitive agency? Extant accounts of cognitive agency tend to focus on belief itself or the event of belief-formation to answer this question, to the exclusion of the (...) activity of maintaining a system of beliefs. This paper argues that a full account of epistemic normativity will need to make sense of this activity as a core locus of cognitive agency. This idea is used to motivate the conclusion that one important and often overlooked kind of epistemic norms is the kind of norms governing the various cognitive activities by which we check, sustain, and adjust our belief systems.

Discussions about the meaning of the word “ought” are pulled in two apparently competing directions. First, in ethical theory this word is used in the paradigmatic statement of ethical principles and conclusions about what some agent is obligated to do. This leads some ethical theorists to claim that the word “ought” describes a real relation, roughly, of being obligated to (realism) or expresses some non-cognitive attitude toward agents acting in certain ways (expressivism). Second, in theoretical linguistics this word is classified (...) as a modal auxiliary verb alongside words like “might,” “may,” “can,” “must,” etc. This leads some theoretical linguists to claim that the word “ought” is a weak necessity modal, which can be modeled with universal quantification over a restricted set of possible worlds. This chapter seeks some resolution of this tension by showing how versions of realism and expressivism can be modified in light of the best semantics of “ought” as a weak necessity modal. In addition, the chapter explains how this semantics might point to a third view—inferentialism—that accounts for the meaning of “ought” not in terms of what relation it describes, nor in terms of what attitude it expresses, but rather in terms of its inferential role.

Recent philosophical debate about the meaning of knowledge claims has largely centered on the question of whether epistemic claims are plausibly thought to be context sensitive. The default assumption has been that sentences that attribute knowledge or justification have stable truth-conditions across different contexts of utterance, once any non-epistemic context sensitivity has been fixed. The contrary view is the contextualist view that such sentences do not have stable truth-conditions but can vary depending on the context of utterance. This debate manifestly (...) presupposes that the meta-epistemological issue of accounting for the meaning of epistemic claims is to be settled by determining the truth-conditions of these claims. I think this presupposition is undermotivated in light of two observations. First, many epistemologists see epistemic claims as evaluative or normative, in some sense. Second, in the meta- ethical debate most philosophers take alternatives to truth-conditional semantics, such as expressivism, as live options when it comes to evaluative or normative claims. As it turns out, I think expressivism doesn’t provide a plausible account of normative concepts across the board. But considering it as an alternative in the meta-epistemological debate points the way to another alternative to truth-conditional semantics. This is a form of inferentialism. In this paper, I try to motivate a move to epistemic inferentialism by showing how it overcomes worries about expressivism and interacts with plausible ideas about the social function epistemic claims play in our commerce with one another and the word.

This is an advanced overview of ethical expressivism.

One’s account of the meaning of ethical sentences should fit – roughly, as part to whole – with one’s account of the meaning of sentences in general. When we ask, though, where one widely discussed account of the meaning of ethical sentences fits with more general accounts of meaning, the answer is frustratingly unclear. The account I have in mind is the sort of metaethical expressivism inspired by Ayer, Stevenson, and Hare, and defended and worked out in more detail recently (...) by Blackburn, Gibbard, and others. So, my first aim (§1) in this paper is to pose this question about expressivism’s commitments in the theory of meaning and to characterize the answer I think is most natural, given the place expressivist accounts attempt to occupy metaethics. This involves appeal to an ideationalist account of meaning. Unfortunately for the expressivist, however, this answer generates a problem; it’s my second aim (§2) to articulate this problem. Then, my third aim (§3) is to argue that this problem doesn’t extend to the sort of account of the meaning of ethical claims that I favor, which is like expressivism in rejecting a representationalist order of semantic explanation but unlike expressivism in basing an alternative order of semantic explanation on inferential role rather than expressive function.

A standard way to explain the connection between ethical claims and motivation is to say that these claims express motivational attitudes. Unless this connection is taken to be merely a matter of contingent psychological regularity, it may seem that there are only two options for understanding it. We can either treat ethical claims as expressing propositions that one cannot believe without being at least somewhat motivated (subjectivism), or we can treat ethical claims as nonpropositional and as having their semantic content (...) constituted by the motivational attitudes they express (noncognitivism). In this paper, we argue that there is another option, which can be recognized once we see that there is no need to build the expression relation between ethical claims and motivational states of mind into the semantic content of ethical claims.

In the past few years, the United States has seen violent street protests in response to police killing unarmed people of color, angry protests by university students concerned about the racist legacy of their institutions, and verbally disruptive protests inside rallies of the (then) Republican nominee for president, Donald Trump. Some of these acts of protest have been clearly legal, protected by the First Amendment of the United States Constitution; others, by contrast, have not, but may nevertheless be be defensible (...) acts of politically motivated disobedience. We are interested here in both legal and illegal acts of protest, but our focus here will be primarily on the latter, for the philosophical literature on protest has focused mostly on illegal cases. Elsewhere, we argue that a fruitful avenue for exploring these issues is to take a speech-act theoretic approach to them. In this paper we compare and contrast this approach with more prominent views of protest (viz., liberal and republican views of civil disobedience). Our goal is to explore the variety of ways in which political dissent, even when it is illegal, may be justified. (shrink)

This article is a critical study of Mark Kalderon's excellent book *Moral Fictionalism*.

Contemporary discussions of expressivism in metaethics tend to run together two quite different antidescriptivist views, and only one of them is subject to the objection about compositional semantics pressed most recently by Schroeder (following Dreier, Unwinn, Hale, Geach and others). Here I distinguish the two versions of expressivism and then go on to suggest that those sympathetic to the second sort of expressivism might improve their account of normative vocabulary and the way it figures in reasoning by making what may (...) seem like a somewhat surprising comparison between normative vocabulary and logical vocabulary. I argue that this comparison brings into view the initial steps towards a third antidescriptivist view in metaethics, which we may see as a pragmatist improvement on the second version of expressivism. (shrink)

In the contemporary metaethical debate, expressivist (Blackburn, Gibbard) and constructivist (Korsgaard, Street) views can be viewed as inspired by irrealist ideas from Hume and Kant respectively. One realist response to these contemporary irrealist views is to argue that they are inconsistent with obvious surface-level appearances of ordinary ethical thought and discourse, especially the fact that we talk and act as if there is ethical knowledge . In this paper, I explore some constructivist and expressivist options for responding to this objection. (...) My conclusion is that, although both constructivists and expressivists can capture other surface-level features of ethical thought and discourse, the possibility of ethical knowledge causes special problems for these versions of irrealism. I end with some comments about where I think irrealists should begin to look for a response to these special problems, which points, somewhat surprisingly, towards an alternative inferentialist form of irrealism about epistemic and ethical thought and discourse, which is inspired by Sellars.

I imagine that people will complain that the account of normative concepts defended in Gibbard’s new book makes the metaethical waters even muddier because it blurs the line between cognitivism and noncognitivism and between realism and antirealism. However, these labels are philosophic tools, and in the wake of Gibbard’s new book, one might rightly conclude that there are new and better philosophical tools emerging on the metaethical scene. The uptake of views about practical reasoning—as exhibited by planning—into debates about the (...) (...) meaning of normative claims is a fruitful line of research. And, as Apt Feelings, Wise Choices made an initial bold step into novel and fruitful lines of research into the connection between psychology and morality, Thinking How to Live has also made an initial bold step into novel and fruitful lines of research into the connection between practical reasoning and normative semantics.

Philosophical debate about the meaning of normative terms has long been pulled in two directions by the apparently competing ideas: (i) ‘ought’s do not describe what is actually the case but rather prescribe possible action, thought, or feeling, (ii) all declarative sentences deserve the same general semantic treatment, e.g. in terms of compositionally specified truth conditions. In this paper, I pursue resolution of this tension by rehearsing the case for a relatively standard truth-conditionalist semantics for ‘ought’ conceived as a necessity (...) modal and proposing a revision to it motivated by the distinctively prescriptive character of some deontic modals. In my view, this puts pressure on a popular conception of one of the core debates of metanormative theory between realists and antirealists. To make good on this claim, I go on to explore two very general ways we might interpret the results of compositional semantics—“representationalism” and “inferentialism”—in order to argue that, contrary to what is generally assumed, both can capture the special prescriptivity of ‘ought’ and both can countenance compositionally specified and informative truth-conditions for ought-sentences. Hence, my main thesis is that the deciding factor between them should not be which of ideas (i) and (ii) we are more impressed by but rather what we think of the relative merits of how representationalism and inferentialism respect these ideas. I’m inclined to favor an antirealist form of inferentialism, but the task I’ve set myself here is mainly to articulate the view in the context of metanormative theory and the semantics of deontic modals rather than try to defend it fully. To this purpose, towards the end I also briefly compare and contrast inferentialism with a third “ideationalist” metasemantic view, which may be an attractive home for some sophisticated versions of metanormative expressivism. Depending on how expressivism is worked out, it may be completely compatible with and so perhaps usefully combined with inferentialism or it may offer a competing way to respect ideas (i) and (ii). (shrink)

In this paper, I consider the prospects of two different kinds of expressivism – ethical expressivism and avowal expressivism – in light of two common objections. The first objection stems from the fact that it is natural to think of ethical statements and avowals as at least potential manifestations of knowledge. The second objection stems from the fact that it is natural to treat ethical statements and avowals as truth-evaluable. I argue that, although a recent avowal expressivist attempt (Bar-On 2004) (...) to meet the second objection may succeed, the related response to the first objection threatens to undermine the principal advantages of that view. Then, I argue that although recent ethical expressivist attempts (especially Blackburn 1998 and Gibbard 2003) to meet the first objection are successful, the related response to the second objection threatens to undermine the principal advantages of that view. This suggests a cross-pollination of defensive strategies, which I go on to explore in order to articulate the theoretical commitments one must take on to make either cross-pollinated position work in the face of both objections. In light of this, I suggest that the prospects for the resulting ethical expressivist position are considerably better than the prospects for the resulting avowal expressivist position, though both positions involve significant theoretical costs.

Davidson, Rorty, and Rosenberg each reject, for similar reasons, the idea that truth is the aim of belief and the goal of inquiry. Rosenberg provides the most explicit and compelling argument for this provocative view. Here, with a focus on this argument, I suggest that this view is a mistake, but not for the reasons some might think. In my view, we can view truth as a constitutive aim of belief even if not a regulative goal of inquiry, if we (...) adopt a Sellarsian view of the ought-to-be’s of belief. Along the way, I suggest that many aspects of Rosenberg’s (unfortunately under-appreciated) epistemology are in fact defensible and are independent of his strong denial of truth's role in constraining epistemic practices.

G. E. Moore famously argued on the basis of semantic intuitions that moral properties are not reducible to natural properties, and therefore that moral predicates refer to nonnatural properties. This clearly represents a version of “moral realism,” but it is a testament to the strength of naturalist intuitions in contemporary philosophical debate that, insofar as one accepts Moore’s arguments, this is typically seen as a boon for antirealists rather than realists. For many philosophers worry that putative nonnatural properties would be (...) too metaphysically and epistemologically queer to be admissible into our ontology. These philosophers conclude that if moral properties cannot be understood as natural properties, then it is more reasonable to abandon commitment to moral properties than to follow Moore into nonnaturalism. -/- In this dialectical milieu, three positions have become popular. Naturalists argue that Moorean arguments are bunk; moral properties can be understood as natural properties. Constructivists argue that Moore was right that moral properties cannot be understood as objective natural properties—that is, the properties that are logically independent of the attitudes of human agents—however, quasi‐objective moral properties can be constructed out of the attitudes of human agents. And noncognitivists argue that moral predicates are nonreferential, and so the best understanding of moral discourse is one which does not construe it as committed to the existence of moral properties. -/- Russ Shafer‐Landau’s new book is distinctive in that it argues against each of these three popular positions while developing and defending a contemporary nonnaturalist version of moral realism.

This paper considers an argument from Rosenberg (Thinking about Knowing, 2002) that truth is not and cannot be the aim of belief. Here, I reconstruct what I take to be the most well worked out version of this idea tracing back to Rorty and Davidson. In response, I also distinguish two things the truth-aim could be: a goal regulating our executable epistemic conduct and an end which determines the types of evaluation, susceptibility to which is partially constitutive of what a (...) belief is.

This paper considers two competing pictures of knowledge of what one ought to do—one which assimilates this to other propositional knowledge conceived as partial ‘locational’ knowledge of where one is in a space of possibilities, the other which distinguishes this from other propositional knowledge by construing it as partial ‘directional’ knowledge of what to do in particular circumstances. I argue that the apparent tension can be lessened by better understanding the contextualized modal-cum-prescriptive nature of ‘ought’ and enriching our conception of (...) the kinds of possibilities within which we can locate ourselves.

Sometimes, when I go to dinner parties organized by my partner, people ask me what I do, and I say that I'm a philosopher. But when I fumble at their questions about ‘my philosophy’, my partner will describe what I do by saying, ‘He uses big words to explain little words.’ Although this is meant tongue in cheek, it's basically right. My philosophical research is mainly in metaethics and the philosophy of language with a focus on the semantics of moral (...) words. This means, for better or worse, that I use big words to explain little words. (shrink)

The word 'ought' is one of the core normative terms, but it is also a modal word. In this book Matthew Chrisman develops a careful account of the semantics of 'ought' as a modal operator, and uses this to motivate a novel inferentialist account of why ought-sentences have the meaning that they have. This is a metanormative account that agrees with traditional descriptivist theories in metaethics that specifying the truth-conditions of normative sentences is a central part of the explanation of (...) their meaning. But Chrisman argues that this leaves important metasemantic questions about what it is in virtue of which ought-sentences have the meanings that they have unanswered. His appeal to inferentialism aims to provide a viable anti-descriptivist but also anti-expressivist answer to these questions. (shrink)

Are moral standards relative to cultures? Are there any moral facts? What is goodness? If there are moral facts how do we learn about them?_ _These are all questions in metaethics, the branch of ethics that investigates the status of morality, the nature of ethical facts, and the meaning of ethical statements. To the uninitiated it can appear abstract and far removed from its two more concrete cousins, ethical theory and applied ethics, yet it is one of the fastest-growing and (...) most exciting areas of ethics. _What is this thing called Metaethics?_ demystifies this important subject and is ideal for students coming to it for the first time. Beginning with a brief historical overview of metaethics and the development of a "conceptual toolkit," Matthew Chrisman introduces and assesses the following key topics: • ethical reality: including questions about naturalism and non-naturalism, moral facts, and the distinction between realism and antirealism • ethical language: does language represent reality? What mental states are expressed by moral statements? • ethical psychology: the Humean theory of motivation and the connection between moral judgement and motivation • ethical knowledge: intuitionist and coherentist moral epistemologies, and theories of objectivity and relativism in metaethics • new directions in metaethics, including non-traditional theories and extensions to metaepistemology and metanormative theory. Additional features such as chapter summaries, questions of understanding, and a glossary make this an ideal introduction to metaethics. (shrink)
