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)

Abstract“Absolutely nothing,” say the radical Bayesians. “Simplifying decisions,” say the moderates. “Providing premises in practical reasoning,” say the epistemologists. “Coordinating with others,” say I. It is hard to see how to construct an adequate theory of rational behavior without using a graded notion of belief, such as credence. But once we have credence, what role is left for belief? After surveying some answers to this question, I will explore the idea that belief is in a different line of work altogether. (...) Its job is not to rationalize and explain an agent’s behavior, but to track what the agent would accept as a reason. Although some philosophers have seen the connection between belief and reasons, they have tended to see reasons as part of a theory of rational action. This locates belief in the rationalizing and explaining business, where it must vie with credence. In contrast, I argue that reasons play no essential role in an account of individual rationality; they are important because we need to coordinate with others. Credence and belief thus answer to separate needs. (shrink)

I use a distinction between single-minded and indifferent choice attitudes, modeled across maximally determinate plans of action, as a basis for interpreting deontic claims – about what ought, ought not, and may be done – as expressing a mode of relation between mind and world that gives voice to the exercise of practical rationality. At the same time, I use maximally determinate possible worlds to model descriptive claims in order to understand them as involving a mode of relation between mind (...) and world that manifests our theoretical rationality. The result is of interest to both linguists looking for a formal treatment of deontic modality that captures the role prescriptive mental states play in our lives, and philosophers interested in substantive questions about action-guiding and representational mental states as exercises of practical and theoretical rationality.

This paper develops a contextualist account of certain recalcitrant embedding phenomena with epistemic modals. I focus on three prominent objections to contextualism from embedding: first, that contextualism mischaracterizes subjects’ states of mind; second, that contextualism fails to predict how epistemic modals are obligatorily linked to the subject in attitude ascriptions; and third, that contextualism fails to explain the persisting anomalousness of so-called “epistemic contradictions” in suppositional contexts. Contextualists have inadequately appreciated the force of these objections. Drawing on a more general (...) framework for implementing a contextualist theory, I argue that we can derive the distinctive embedding behavior of epistemic modals from a particular contextualist interpretation of a standard semantics for modals, general mechanisms of local interpretation, and typical features of discourse contexts. Examining embedding phenomena with epistemic modals raises difficult broader issues about conventionalization and pragmatic reasoning, the varieties of context-sensitive language, and the roles of context in interpretation. The paper concludes by briefly examining how the proposed contextualist account compares with certain relativist/expressivist accounts. (shrink)

This paper argues that there is a class of terms, or uses of terms, that are best accounted for by an expressivist account. We put forward two sets of criteria to distinguish between expressive and factual terms. The first set relies on the action-guiding nature of expressive language. The second set relies on the difference between one's evidence for making an expressive vs. factual statement. We then put those criteria to work to show, first, that the basic evaluative adjectives such (...) as ‘good’ have expressive as well as factual uses and, second, that many adjectives whose primary meanings are factual, such as ‘powerful’, also have expressive uses.

Expressivism promises an illuminating account of the nature of normative judgment. But worries about the details of expressivist semantics have led many to doubt whether expressivism's putative advantages can be secured. Drawing on insights from linguistic semantics and decision theory, I develop a novel framework for implementing an expressivist semantics that I call ordering expressivism. I argue that by systematically interpreting the orderings that figure in analyses of normative terms in terms of the basic practical attitude of conditional weak preference, (...) the expressivist can explain the semantic properties of normative sentences in terms of the logical properties of that attitude. Expressivism's problems with capturing the logical relations among normative sentences can be reduced to the familiar, more tractable problem of explaining certain coherence constraints on preferences. Particular attention is given to the interpretation of wide-scope negation. The proposed solution is also extended to other types of embedded contexts—most notably, disjunctions. (shrink)
