Using a vague predicate can make commitments about the appropriate use of that predicate in the remaining part of the discourse. For instance, if I assert that some particular pig is fat, I am committed to judging any fatter pig to be fat as well. We can model this update effect by recognizing that truth depends both on the state of the world and on the state of the discourse: the truth conditions of ‘This pig is fat’ rule out evaluation (...) points for which the pig in question in world w is thinner than the cutoff for fatness in the discourse d. Then disagreements about taste are disagreements about the discourse. Unlike disagreements about the world, disagreements about the discourse can be faultless, given that none of the discourse participants has privileged authority to make pronouncements about conventions for appropriate use of a predicate. Thus on the dynamic view developed here, whether or not a dispute about taste turns out to be faultless depends in part on predictable features of the previous discourse. On this account, faultless disagreement involving predicates of personal taste does not force relativizing truth to a judge or assessor. (shrink)

On Kratzer’s canonical account, modal expressions (like “might” and “must”) are represented semantically as quantifiers over possibilities. Such expressions are themselves neutral; they make a single contribution to determining the propositions expressed across a wide range of uses. What modulates the modality of the proposition expressed—as bouletic, epistemic, deontic, etc.—is context.2 This ain’t the canon for nothing. Its power lies in its ability to figure in a simple and highly unified explanation of a fairly wide range of language use. Recently, (...) though, the canon’s neat story has come under attack. The challenge cases involve the epistemic use of a modal sentence for which no single resolution of the contextual parameter appears capable of accommodating all our intuitions.3 According to these revisionaries, such cases show that the canonical story needs to be amended in some way that makes multiple bodies of information relevant to the assessment of such statements. Here I show that how the right canonical, flexibly contextualist account of modals can accommodate the full range of challenge cases. The key will be to extend Kratzer’s formal semantic account with an account of how context selects values for a modal’s.. (shrink)

(1992). TROUBLES FOR NEW WAVE MORAL SEMANTICS: THE ‘OPEN QUESTION ARGUMENT’ REVIVED. Philosophical Papers: Vol. 21, No. 3, pp. 153-175. doi: 10.1080/05568649209506380.

This paper advances a reductive semantics for ‘ought’ and a naturalistic theory of normativity. It gives a unified analysis of predictive, instrumental, and categorical uses of ‘ought’: the predictive ‘ought’ is basic, and is interpreted in terms of probability. Instrumental ‘oughts’ are analyzed as predictive ‘oughts’ occurring under an ‘in order that’ modifer (the end-relational theory). The theory is then extended to categorical uses of ‘ought’: it is argued that they are special rhetorical uses of the instrumental ‘ought’. Plausible conversational (...) principles explain how this end-relational ‘ought’ can perform the expressive functions of the moral ‘ought’. The notion of an ‘ought-simpliciter’ is also discussed.

Recent research has investigated whether people think of their moral beliefs as objectively true facts about the world, or as subjective preferences. The present research examines variability in the perceived objectivity of different moral beliefs, with respect both to the content of moral beliefs themselves (what they are about), and to the social representation of those moral beliefs (whether other individuals are thought to hold them). It also examines the possible consequences of perceiving a moral belief as objective. With respect (...) to the content of moral beliefs, we find that beliefs about the moral properties of negatively valenced acts are seen as reliably more objective than beliefs about the moral properties of positively valenced acts. With respect to the social representation of moral beliefs, we find that the degree of perceived consensus regarding a moral belief positively influences its perceived objectivity. The present experiments also demonstrate that holding a moral belief to be objective is associated with a more ‘closed’ response in the face of disagreement about it, and with more morally pejorative attributions towards a disagreeing other person.

This paper addresses three problems: the problem of formulating a coherent relativism, the Sorites paradox and a seldom noticed difficulty in the best intuitionistic case for the revision of classical logic. A response to the latter is proposed which, generalised, contributes towards the solution of the other two. The key to this response is a generalised conception of indeterminacy as a specific kind of intellectual bafflement-Quandary. Intuitionistic revisions of classical logic are merited wherever a subject matter is conceived both as (...) liable to generate Quandary and as subject to a broad form of evidential constraint. So motivated, the distinctions enshrined in intuitionistic logic provide both for a satisfying resolution of the Sorites paradox and a coherent outlet for relativistic views about, e.g., matters of taste and morals. An important corollary of the discussion is that an epistemic conception of vagueness can be prised apart from the strong metaphysical realism with which its principal supporters have associated it, and acknowledged to harbour an independent insight.

Many philosophers, in different areas, are tempted by what variously goes under the name of Contextualism, Speaker Relativism, Indexical Relativism. (I’ll just use Indexical Relativism in this paper.) Thinking of certain problematic expressions as deriving their content from elements of the context of use solves some problems. But it faces some problems of its own, and in this paper I’m interested in one in particular, namely, the problem of disagreement. Two alternative theories, tempting for just the same kinds of expressions (...) as Indexical Relativism is meant to handle, promise to solve the problem of disagreement. I’ll argue that they do not live up to their promise. At the end of the paper, I’ll ask what exactly disagreement amounts to, and I’ll canvass some purported solutions. (shrink)

We offer a new argument in favour of metanormative contextualism, the thesis that the semantic value of a normative ‘ought’ claim of the form ‘ S ought to Φ’ depends on the value of one or more parameters whose values vary in a way that is determined by the context of utterance. The debate over this contextualist thesis has centred on cases that involve ‘ought’ claims made in the face of uncertainty regarding certain descriptive facts. Contextualists, relativists, and invariantists all (...) have plausible ways of explaining these cases, and one could reasonably judge the debate between these views to be a stalemate. We argue that this stalemate can be broken by shifting focus to a case that involves normative uncertainty rather than descriptive uncertainty. While relativist and invariantist rivals of contextualism can give plausible accounts of the descriptive uncertainty cases, only contextualism can provide a plausible account of the normative uncertainty case.

Considerations involving disagreement, as well as related considerations involving correction and retraction, have played an important role in recent debates about epistemic modals. For instance, it has been argued that contextualist views about epistemic modals have problems when it comes to explaining cases of disagreement. In response to these challenges, I explore the idea that the relevant cases of disagreement may involve credal disagreement. In a case of credal disagreement, the parties have different degrees of belief or credences. There does (...) not have to be a difference in outright beliefs in order for the parties to disagree. I argue that the idea of credal disagreement allows us to make sense of otherwise problematic cases of disagreement involving epistemic modals. I also discuss how these ideas can be extended to cases of correction and retraction. (shrink)

What happens to the "conversational score" when speakers in a conversation push the score for a context-sensitive term in different directions? In epistemology, contextualists are often construed as holding that both the skeptic ("You don't know!") and her opponent ("Oh, yes I do!") speak truthfully when they debate. This assumes a "multiple scoreboards" version of contextualism. But contextualists themselves typically opt for "single scoreboard" views on which such apparently competing claims really do conflict. This paper explores several single scoreboard options (...) for contextualists, opting in the end for the "gap view," on which neither of our debaters speaks truthfully. (shrink)

By “epistemic modals,” I mean epistemic uses of modal words: adverbs like “necessarily,” “possibly,” and “probably,” adjectives like “necessary,” “possible,” and “probable,” and auxiliaries like “might,” “may,” “must,” and “could.” It is hard to say exactly what makes a word modal, or what makes a use of a modal epistemic, without begging the questions that will be our concern below, but some examples should get the idea across. If I say “Goldbach’s conjecture might be true, and it might be false,” (...) I am not endorsing the Cartesian view that God could have made the truths of arithmetic come out differently. I make the claim not because I believe in the metaphysical contingency of mathematics, but because I know that Goldbach’s conjecture has not yet been proved or refuted. Similarly, if I say “Joe can’t be running,” I am not saying that Joe’s constitution prohibits him from running, or that Joe is essentially a non-runner, or that Joe isn’t allowed to run. My basis for making the claim may be nothing more than that I see Joe’s running shoes hanging on a hook. (shrink)

Epistemic modals are standardly taken to be context-dependent quantifiers over possibilities. Thus sentences containing them get truth-values with respect to both a context and an index. But some insist that this relativization is not relative enough: `might'-claims, they say, only get truth-values with respect to contexts, indices, and—the new wrinkle—points of assessment (hence, CIA). Here we argue against such "relativist" semantics. We begin with a sketch of the motivation for such theories and a generic formulation of them. Then we catalogue (...) central problems that any such theory faces. We end by outlining an alternative story. (shrink)

The term 'indexical' comes into the philosophy of language from Charles Sanders Peirce's use of the term 'index'. Paradigm indexicals include pronouns such as 'I' and 'you', as well as words like 'here', 'now', 'today', 'tomorrow', and 'yesterday' that occur as both nouns and adverbs. This chapter looks at how such paradigms work, then look at less paradigmatic examples, and eventually try to arrive at plausible definitions of indexical and indexicality. Eliminative theories treat indexicals as short‐cuts for descriptions that the (...) speaker has in mind. Indexicals play no essential role in language and communication and can be eliminated for serious purposes. The chapter reviews McTaggart's use of indexicals in his famous argument about time. In fact indexicals, for all their conversational utility and humble origins, seem indispensable in talking about philosophical topics. Simple and untechnical ‘I’ and ‘now’ may be, compared to words that embody great insights of science or philosophy, they still are words, that express ideas, and connect with complex thoughts words can express.

There have been times in the history of ethical theory, especially in this century, when moral realism was down, but it was never out. The appeal of this doctrine for many moral philosophers is apparently so strong that there are always supporters in its corner who seek to resuscitate the view. The attraction is obvious: moral realism purports to provide a precious philosophical good, viz., objectivity and all that this involves, including right answers to (most) moral questions, and the possibility (...) of knowing those answers. In the last decade, moral realism has re-entered the philosophical ring in powerful-looking naturalistic form. ln this paper we provide a dialectical overview: we situate the new wave position itself, and also our objections to it, in the context of the evolving program of philosophical naturalism in 20th century analytic philosophy. We seek to show that although this new contender might initially look like championship material, it succumbs to punches surprisingly similar to those that knocked out the old-fashioned versions of naturalist moral realism.

Invariantism about ‘might’ says that ‘might’ semantically expresses the same modal property in every context. This paper presents and defends a version of invariantism. According to it, ‘might’ semantically expresses the same weak modal property in every context. However, speakers who utter sentences containing ‘might’ typically assert propositions concerning stronger types of modality, including epistemic modality. This theory can explain the phenomena that motivate contextualist theories of epistemic uses of ‘might’, and can be defended from objections of the sort that (...) relativists mount against contextualist theories.

Cappelen and Hawthorne present a powerful critique of fashionable relativist accounts of truth, and the foundational ideas in semantics on which the new relativism draws. They argue compellingly that the contents of thought and talk are propositions that instantiate the fundamental monadic properties of truth and falsity.
