Adopting a dispositional theory of value promises to deliver a lot of theoretical goodies. One recurring problem for dispositional theories of value, though, is a problem about nonconvergence. If being a value is being disposed to elicit response R in us, what should we say if it turns out that not everybody is disposed to have R to the same things? One horn of the problem here is a danger of the view collapsing into an error theory—of it turning out, (...) on account of the diversity of agents' relevant dispositions, that nothing is really a value, since nothing is disposed to elicit R in everybody. Alternatively, there is a danger of an objectionable fragmentation of value, according to which there is no such thing as a value simpliciter, but only valuesme and valuesyou, valuesus and valuesthem. I advocate a de se relativist version of a dispositional theory of value. If we go for this sort of de-se-ified dispositional theory, we get to keep our theoretical goodies, but we avoid the problem of nonconvergence that leads to a danger of either collapse into an error theory, or else talking-past, and a loss of common subject matter.

Expressivists and relativists about epistemic modals often motivate their view by arguing against contextualist treatments of certain cases. However, I argue that even expressivists and relativists should consider being a kind of contextualist. Specifically, data involving mixed disjunctions motivate taking epistemic modals to be sensitive to contextually-salient partitions, and thus context-sensitive.

In the pair of articles of which this is the first, I shall present a set of problems and philosophical proposals that have in recent years been associated with the term “relativism”. All these problems and proposals concern the question of how we should represent thought and speech about certain topics. The main issue here is whether we should model such mental states or linguistic acts as involving representational contents that are absolutely correct or incorrect, or whether, alternatively, their correctness (...) should be thought of as varying with some (more or less surprising) factor. In this, first, article, I shall discuss the general issue of relativism about representational content. I shall claim that there are legitimate ways of attributing contents that are absolute truth-bearers, and there are also equally legitimate ways of attributing relativistic representational contents. In the companion piece “Relativism 2: Semantic Content”, I look in more detail at the more specific question whether semantic contents (i.e. the contents assigned to linguistic utterances in the semantics of natural language) should be construed in an absolutist or a relativist way.

In the present continuation, I look in more detail at a special case of the general issue, namely the question of whether semantic contents, i.e. the contents assigned to linguistic utterances in the semantics of natural language, should be construed in an absolutist or in a relativist way.

In this paper, I consider a variant of the ancient Idle Argument involving so‐called “unconditionals” with interrogative antecedents. This new Idle Argument provides an ideal setting for probing the logic of these close relatives of if‐conditionals, which has been comparatively underexplored. In the course of refuting the argument, I argue that contrary to received wisdom, many unconditionals do not entail their main clauses, yet modus ponens is still unrestrictedly valid for this class of expressions. I make these lessons precise in (...) a formal system drawing on recent work in inquisitive semantics. My larger aim is to challenge standard truth preservation accounts of logic and deductive argumentation. (shrink)

What we can call asymmetric disagreement occurs when one agent is in disagreement with another, but not vice-versa. In this paper, I give an example of and develop a framework for understanding this phenomenon. One pivotal feature of my example is that one of the agents in the scenario has a belief about what might be the case—a might-belief. I show that a traditional account of might-beliefs and disagreement cannot explain the initially surprising phenomenon of asymmetric disagreement. In order to (...) provide an explanation, I develop a dynamic account of might-beliefs and a corresponding account of disagreement. I close by exploring a choice point for our account—showing that the simple dynamic account has some controversial (though, perhaps, true) consequences. I explore how revisionary notions of validity, inconsistency, and disagreement can allow us to avoid these consequences if we wish. (shrink)

There is a common assumption in the semantics of modal auxiliaries in natural language; in utterances of MOD φ , where MOD is a modal and φ is the prejacent, context determines the particular flavor of modality expressed by the modal. Such is the standard contextualist semantics of Kratzer and related proposals. This winds up being a problem, because there is a significant class of modals which have constraints on the admissible modal flavor that are not traceable to context. For (...) example, in MUST φ , subsentential properties of φ, like the aspectual class of the predicate in the prejacent, can affect the flavor of MUST. By encoding the above assumption into the semantics, such contextualist accounts fail to be able to explain, much less to predict, this pattern. Worse yet, attempts to exploit the resources of the theory in service of an explanation run afoul of important commitments of the view, like the hypothesis that modals have a uniform semantics. Given these circumstances, these data might seem like a justification for dispensing with the uniformity hypothesis. The present paper lays out the above problem in detail. Against the pessimistic view, I argue that the the contextualist account can in fact explain and predict these patterns while preserving the uniformity hypothesis. This requires adopting an amendment to the semantics of modals based on the work of Valentine Hacquard. Aside from maintaining the contextualist paradigm and preserving uniformity, the proposal also clarifies the role of context in the interpretation of modals. As it will turn out, the role of context ought to be circumscribed in its flavor-determining role for modals. (shrink)

This paper surveys some ways in which epistemic reasons ascriptions (or ERAs) appear to be context-sensitive, and outlines a framework for thinking about the nature of this context-sensitivity that is intimately related to ERAs' explanatory function.

This paper considers some questions related to the determination of epistemic modal domains. Specifically, given situations in which groups of agents have epistemic states that bear on a modal domain, how is the domain best restricted? This is a metasemantic project, in which I combine a standard semantics for epistemic modals, as developed by Kratzer, with a standard story about conversational dynamics, as developed by Stalnaker. I show how a standard framework for epistemic logic can model their interaction. I contend (...) that if groups have epistemic states that bear on the modal domain, as the data suggests, then careful attention must be paid to the method of combination selected for the epistemic states of the individuals within the group. Specifically, there should be some explanation of the flow of information in a group-deliberative setting. Through this study we find a novel explanation of modal disagreement and uptake. (shrink)

This paper develops a compositional, type-driven constraint semantic theory for a fragment of the language of subjective uncertainty. In the particular application explored here, the interpretation function of constraint semantics yields not propositions but constraints on credal states as the semantic values of declarative sentences. Constraints are richer than propositions in that constraints can straightforwardly represent assessments of the probability that the world is one way rather than another. The richness of constraints helps us model communicative acts in essentially the (...) same way that we model agents’ credences. Moreover, supplementing familiar truth-conditional theories of epistemic modals with constraint semantics helps capture contrasts between strong necessity and possibility modals, on the one hand, and weak necessity modals, on the other.

Traditional epistemologists assumed that the most important doxastic norms were rational requirements on belief. This orthodoxy has recently been challenged by the work of revolutionary epistemologists on the rational requirements on credences. Revolutionary epistemology takes it that such contemporary work is important precisely because traditional epistemologists are mistaken—credal norms are more fundamental than, and determinative of, belief norms. To make sense of their innovative project, many revolutionary epistemologists have also adopted another commitment, that norms on credences are governed by a (...) fundamental accuracy norm. Unfortunately for the revolutionary epistemologist, it has been difficult to define a measure of accuracy while maintaining that credal norms are more basic than belief norms. In this paper, I criticize one such proposal for measuring accuracy, that the accuracy of our credences should be assessed in terms of what we know, arguing that this picture ultimately cannot vindicate the revolutionary approach.

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)

There is an interesting contrast between permissions to act and permissions to believe. Plausibly, if it is permissible to believe something from a perspective with incomplete evidence, it cannot become impermissible to believe it from a second perspective with complete evidence. In contrast, it seems that something permissible to do for an agent in a perspective with limited evidence can become impermissible in a second perspective in which all the relevant evidence is available. What is more, an agent with incomplete (...) evidence may be permitted to do something that she knows would be impermissible if she occupied a perspective of complete evidence. In this paper, I argue that this contrast is explained by a disanalogy between the role played by belief in epistemic deliberation and the role played by action in practical deliberation. Epistemic deliberation may be closed by adopting other attitudes than belief, whereas in general, practical deliberation can only be closed by endorsing some course of action. Thus, when there are pressures to close some practical deliberation, agents have to make a decision about what to do even if they lack relevant information. By contrast, lacking relevant evidence, agents may always refrain from forming a belief and close instead their epistemic deliberation by adopting some other attitude. (shrink)

This paper argues that several leading theories of subjunctive conditionals are incompatible with ordinary intuitions about what credences we ought to have in subjunctive conditionals. In short, our theory of subjunctives should intuitively display semantic humility, i.e. our semantic theory should deliver the truth conditions of sentences without pronouncing on whether those conditions actually obtain. In addition to describing intuitions about subjunctive conditionals, I argue that we can derive these ordinary intuitions from justified premises, and I answer a possible worry (...) for my derivation by refuting a subjunctive triviality result modeled on (Lewis 1976). I conclude that the debate over the correct theory of subjunctive conditionals requires settling meta-philosophical questions about the relative value of various virtues of first-order theories of subjunctive conditionals.

I defend a contextualist account of bare epistemic modal claims against recent objections. I argue that in uttering a sentence of the form ‘It might be that p,’ a speaker is performing two speech acts. First, she is (directly) asserting that in view of the knowledge possessed by some relevant group, it might be that p. The content of this first speech act is accounted for by the contextualist view. But the speaker's utterance also generates an indirect speech act that (...) consists in a weak suggestive that p. Since this second speech act is typically the main point of a bare epistemic modal utterance, our (negative or positive) responses to the utterance actually target this second speech act. I show how this two-speech-act account can explain the data recently adduced against contextualism. (shrink)

I argue against a simple contextualist account of epistemic modals. My argument, like the argument on which it is based , charges that simple contextualism cannot explain all of the conversational data about uses of epistemic modals. My argument improves on its predecessor by insulating itself from recent contextualist attempts by Janice Dowell and Igor Yanovich to get around that argument. In particular, I use linguistic data to show that an utterance of an epistemic modal sentence can be warranted, while (...) an utterance of its suggested simple contextualist paraphrase is not.

What is objectivity? What would it take to have objective representations and do we (humans) have what it takes? This paper aims to contribute to answering these questions. To this end, it isolates one relevant sense of objectivity and proposes a generalization of standard frameworks of representational content in order to engage with the question in a way that is rhetorically fair. Armed with a general conception of perspectival content, taken from the literature on centred orde secontent, the paper articulates (...) one necessary condition for objective representation: the possession of objective concepts and therefore objective contents. Two ways of meeting (or approximately meeting) this condition are discussed in an exploratory way. (shrink)

The Ramseyan thesis that the probability of an indicative conditional is equal to the corresponding conditional probability of its consequent given its antecedent is both widely confirmed and subject to attested counterexamples (e.g., McGee 2000, Kaufmann 2004). This raises several puzzling questions. For instance, why are there interpretations of conditionals that violate this Ramseyan thesis in certain contexts, and why are they otherwise very rare? In this paper, I raise some challenges to Stefan Kaufmann's account of why the Ramseyan thesis (...) sometimes fails, and motivate my own theory. On my theory, the proposition expressed by an indicative conditional is partially determined by a background partition, and hence its probability depends on the choice of such a partition. I hold that this background partition is contextually determined, and in certain conditions is set by a salient question under discussion in the context. I show how the resulting theory offers compelling answers to the puzzling questions raised by failures of the Ramseyan thesis. (shrink)

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)

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. (shrink)

Recent challenges to Kratzer’s canonical contextualist semantics for modal expressions are united by a shared methodological practice: Each requires the assessment of the truth or warrant of a sentence in a scenario. The default evidential status accorded these judgments is a constraining one: It is assumed that, to be plausible, a semantic hypothesis must vindicate the reported judgments. Fully assessing the extent to which these cases do generate data that puts pressure on the canonical semantics, then, requires an understanding of (...) this methodological practice. Here I argue that not all assessments are fit to play this evidential role. To play it, we need reason to think that speakers’ assessments can be reasonably expected to be reliable. Minimally, having such grounds requires that assessments are given against the background of non-defectively characterized points of evaluation. Assessing MacFarlane’s central challenge case to contextualism about deontic modals in light of this constraint shows that his judgments do not have the needed evidential significance. In addition, new experimental data shows that once the needed scenario is characterized non-defectively, none of the resulting range of cases provides data that cannot be accommodated by a Kratzer-style contextualism.

According to a popular closure principle for epistemic justification, if one is justified in believing each of the premises in set Φ and one comes to believe that ψ on the basis of competently deducing ψ from Φ—while retaining justified beliefs in the premises—then one is justified in believing that ψ. This principle is prima facie compelling; it seems to capture the sense in which competent deduction is an epistemically secure means to extend belief. However, even the single-premise version of (...) this closure principle is in conflict with certain seemingly good inferences involving the epistemic possibility modal ♢. According to other compelling principles concerning competent deduction and epistemic justification, one can competently infer ¬♢φ from ¬φ in deliberation even though there are cases in which one can justifiably believe ¬φ but would be unjustified in believing ¬♢φ. Thus, as we argue, philosophers must choose between unrestricted closure for justification and the validity of these other principles. (shrink)

Claims about needs are a ubiquitous feature of everyday practical discourse. It is therefore unsurprising that needs have long been a topic of interest in moral philosophy, applied ethics, and political philosophy. Philosophers have devoted much time and energy to developing theories of the nature of human needs and the like. -/- Philosophers working on needs are typically committed to the idea that there are different kinds of needs and that within the different kinds of needs is a privileged class (...) of needs that is especially normatively significant. -/- Some philosophers go further and make rather grand claims about needs. They claim that needs are central or fundamental to moral thinking and that we must have a needs-centred moral theory or a general reorientation of moral philosophy around needs. -/- In this paper I aim to do two things. First, to show how applying recent work on modal terms can help us to understand thought and talk about needs. This is the positive part. I then use these ideas to cast doubt on the more ambitious claims about needs. Put briefly, a proper understanding of claims about needs undermines the idea that the concept of needs is fundamental in moral thought or in moral philosophy. Ambitious needs theory fails. (shrink)

This paper observes that in the midst of a thickening debate over the concept of “epistemic possibility,” nearly every philosopher assumes that the concept is equivalent to a mere absence of epistemic impossibility, that a proposition is epistemically possible if and only if our knowledge does not entail that it is false. I suggest that it is high time that we challenge this deeply entrenched assumption. I assemble an array of data that singles out the distinctive meaning and function of (...) epistemic possibility, which suggest it to be distinct from other modals and an attitude toward a proposition, not a part of the content of a proposition. I suggest that this data is best explained by a positive evidentialist conception of epistemic possibility, one which maintains that a proposition is epistemically possible to a subject only if there is evidence specifically in support of that proposition that is cognitively available to that subject. I suggest that this view not only offers a superior explanation of the data, but also offers a unique and straightforward strategy for undermining skeptical arguments. (shrink)
