ABSTRACTRecent debate over the semantics and pragmatics of epistemic modals has focused on intuitions about cross-contextual truth-value assessments. In this paper, we advocate a different approach to evaluating theories of epistemic modals. Our strategy focuses on judgments of the incompatibility of two different epistemic possibility claims, or two different truth value assessments of a single epistemic possibility claim. We subject the predictions of existing theories to empirical scrutiny, and argue that existing contextualist and relativist theories are unable to account for (...) the full pattern of observed judgments. As a way of illustrating the theoretical upshot of these results, we conclude by developing a novel theory of epistemic modals that is able to predict the results. (shrink)

I argue that not all context dependent expressions are alike. Pure (or ordinary) indexicals behave more or less as Kaplan thought. But quasi indexicals behave in some ways like indexicals and in other ways not like indexicals. A quasi indexical sentence φ allows for cases in which one party utters φ and the other its negation, and neither party’s claim has to be false. In this sense, quasi indexicals are like pure indexicals (think: “I am a doctor”/“I am not a (...) doctor” as uttered by different individuals). In such cases involving a pure indexical sentence, it is not appropriate for the two parties to reject each other’s claims by saying, “No.” However, in such cases involving a quasi indexical sentence, it is appropriate for the par- ties to reject each other’s claims. In this sense, quasi indexicals are not like pure indexicals. Drawing on experimental evidence, I argue that gradable adjectives like “rich” are quasi indexicals in this sense. e existence of quasi indexicals raises trouble for many existing theories of context dependence, including standard contextualist and relativist theories. I propose an alternative semantic and pragmatic theory of quasi indexicals, negotiated contextualism, that combines insights from Kaplan 1989 and Lewis 1979. On my theory, rejection is licensed with quasi indexicals (even when neither of the claims involved has to be false) because the two utterances involve conflicting proposals about how to update the conversational score. I also adduce evidence that conflicting truth value assessments of a single quasi indexical utterance exhibit the same behavior. I argue that negotiated contextualism can account for this puzzling property of quasi indexicals as well. (shrink)

A series of recent studies have explored the impact of people's judgments regarding physical law, morality, and probability. Surprisingly, such studies indicate that these three apparently unrelated types of judgments often have precisely the same impact. We argue that these findings provide evidence for a more general hypothesis about the kind of cognition people use to think about possibilities. Specifically, we suggest that this aspect of people's cognition is best understood using an idea developed within work in the formal semantics (...) tradition, namely the notion of modality. On the view we propose, people may have separate representations for physical, moral and probabilistic considerations, but they also integrate these various considerations into a unified representation of modality.

This thesis addresses philosophical problems concerning improper assertions. The first part considers the issue of defining lying: here, against a standard view, I argue that a lie need not intend to deceive the hearer. I define lying as an insincere assertion, and then resort to speech act theory to develop a detailed account of what an assertion is, and what can make it insincere. Even a sincere assertion, however, can be improper (e.g., it can be false, or unwarranted): in the (...) second part of the thesis, I consider these kinds of impropriety. An influential hypothesis maintains that proper assertions must meet a precise epistemic standard, and several philosophers have tried to identify this standard. After reviewing some difficulties for this approach, I provide an innovative solution to some known puzzles concerning the permissibility of false assertions. In my view, assertions purport to aim at truth, but they are not subject to a norm that requires speakers to assert a proposition only if it is true. (shrink)

It is often assumed that when one party felicitously rejects an assertion made by an- other party, the first party thinks that the proposition asserted by the second is false. This assumption underlies various disagreement arguments used to challenge contex- tualism about some class of expressions. As such, many contextualists have resisted these arguments on the grounds that the disagreements in question may not be over the proposition literally asserted. The result appears to be a dialectical stalemate, with no independent (...) method of determining whether any particular instance of disagreement is over the proposition literally asserted. In this paper, I propose an independent method for assessing whether a disagreement is about what’s literally asserted. Focusing on epistemic modals throughout, I argue that this method provides evidence that some epistemic modal disagreements are in fact not over the proposition literally asserted by the utterance of the epistemic modal sentence. This method provides a way to break the stalemate, and reveals a new data point for theories of epistemic modals to predict—that is, how there can be such modal disagreements. In the rest of the paper, I motivate a general theory of how to predict these kinds of disagreements, and then offer some brief remarks about how contextualist, relativist, and expressivist theories of epistemic modals might accommodate this new data point.

The arguments for and against a truth-relativist semantics for propositional knowledge attributions (KTR) have been debated almost exclusively in the philosophy of language. But what implications would this semantic thesis have in epistemology? This question has been largely unexplored. The aim of this paper is to establish and critique several ramifications of KTR in mainstream epistemology. The first section of the paper develops, over a series of arguments, the claim that MacFarlane's (2005, 2010) core argument for KTR ultimately motivates (for (...) better or worse) the extension of a truth-relativist semantics to a subset of understanding attributions – attributions of understanding-why. I conclude by presenting some reasons to think that even if KTR were otherwise plausible, a truth-relativist semantics for understanding-why attributions is not. These claims, taken together, constitute a kind of epistemological argument against MacFarlane-style truth-relativism for knowledge attributions. (shrink)

I investigate the implication of the truth-relativist’s alleged ‘ faultless disagreements’ for issues in the epistemology of disagreement. A conclusion I draw is that the type of disagreement the truth-relativist claims to preserve fails in principle to be epistemically significant in the way we should expect disagreements to be in social-epistemic practice. In particular, the fact of faultless disagreement fails to ever play the epistemically significant role of making doxastic revision rationally required for either party in a disagreement. That the (...) truth-relativists’ disagreements over centred content fail to play this epistemically significant role that disagreements characteristically play in social epistemology should leave us sceptical that disagreement is what the truth-relativist has actually preserved.

In “Epistemic Modals,” Seth Yalcin argues that what explains the deficiency of sentences containing epistemic modals of the form ‘p and it might be that not-p’ is that sentences of this sort are strictly contradictory, and thus are not instances of a Moore-paradox as has been previous suggested. Benjamin Schnieder, however, argues in his Yalcin’s explanation of these sentences’ deficiency turns out to be insufficiently general, as it cannot account for less complex but still defective sentences, such as ‘Suppose it (...) might be raining.’ Consequently, Schnieder proposes his own, expressivist treatment of epistemic modals which he thinks can explain the deficiency of both the original sentence type as well as more complex cases of embedded sentences containing epistemic modals. In this study, I argue that although Schnieder is right to draw our attention to the explanatory failure of Yalcin’s account, we aren’t forced to adopt Schnieder’s expressivist account of epistemic modals. I defend instead a contextualist-friendly alternative which explains the deficiencies of all the relevant sentence types, while avoiding both the defects of Yalcin’s account and the intuitive costs of expressivism.

It has often been suggested that people's ordinary understanding of morality involves a belief in objective moral truths and a rejection of moral relativism. The results of six studies call this claim into question. Participants did offer apparently objectivist moral intuitions when considering individuals from their own culture, but they offered increasingly relativist intuitions considering individuals from increasingly different cultures or ways of life. The authors hypothesize that people do not have a fixed commitment to moral objectivism but instead tend (...) to adopt different views depending on the degree to which they consider radically different perspectives on moral questions.

The Sleeping Beauty puzzle provides a nice illustration of the approach to self-locating belief defended by Robert Stalnaker in Our Knowledge of the Internal World (Stalnaker, 2008), as well as a test of the utility of that method. The setup of the Sleeping Beauty puzzle is by now fairly familiar. On Sunday Sleeping Beauty is told the rules of the game, and a (known to be) fair coin is flipped. On Monday, Sleeping Beauty is woken, and then put back to (...) sleep. If, and only if, the coin landed tails, she is woken again on Tuesday after having her memory of the Monday awakening erased.1 On Wednesday she is woken again and the game ends. There are a few questions we can ask about Beauty’s attitudes as the game progresses. We’d like to know what her credence that the coin landed heads should be (a) Before she goes to sleep Sunday; (b) When she wakes on Monday; (c) When she wakes on Tuesday; and (d) When she wakes on Wednesday? Standard treatments of the Sleeping Beauty puzzle ignore (d), run together (b) and (c) into one (somewhat ill-formed) question, and then divide theorists into ‘halfers’ or ‘thirders’ depending on how they answer it. Following Stalnaker, I’m going to focus on (b) here, though I’ll have a little to say about (c) and (d) as well. I’ll be following orthodoxy in taking 1 2 to be the clear answer to (a), and in taking the correct answers to (b) and (c) to be independent of how the coin lands, though I’ll briefly question that assumption at the end. An answer to these four questions should respect two different kinds of constraints. The answer for day n should make sense ‘statically’. It should be a sensible answer to the question of what Beauty should do given what information she then has. And the answer should make sense ‘dynamically’. It should be a sensible answer to the question of how Beauty should have updated her credences from some earlier day, given rational credences on the earlier day. As has been fairly clear since the discussion of the problem in Elga (2000), Sleeping Beauty is puzzling because static and dynamic considerations appear to push in different directions.. (shrink)

Attempts to clarify some issues about the use of hidden arguments to predicates of personal taste, and motivate an analysis which does not make use of such arguments.

Defined narrowly, epistemology is the study of knowledge and justified belief. As the study of knowledge, epistemology is concerned with the following questions: What are the necessary and sufficient conditions of knowledge? What are its sources? What is its structure, and what are its limits? As the study of justified belief, epistemology aims to answer questions such as: How we are to understand the concept of justification? What makes justified beliefs justified? Is justification internal or external to one's own mind? (...) Understood more broadly, epistemology is about issues having to do with the creation and dissemination of knowledge in particular areas of inquiry. This article will provide a systematic overview of the problems that the questions above raise and focus in some depth on issues relating to the structure and the limits of knowledge and justification.

Relativism, roughly put, is the view that truth and falsity, right and wrong, standards of reasoning, and procedures of justification are products of differing conventions and frameworks of assessment and that their authority is confined to the context giving rise to them. More precisely, ‘relativism’ covers views which maintain that—at a level of high abstraction—at least some class of things have properties they have not simpliciter, but only relative to a given framework of assessment, and correspondingly, that the truth of (...) claims attributing these properties holds only once the relevant framework of assessment is specified or supplied. Relativists characteristically insist, furthermore, that if something is only relatively so, then there can be no framework-independent vantage point from which the matter of whether the thing in question is so can be established. Relativism has been, in its various guises, both one of the most popular and most reviled philosophical doctrines of our time. Defenders see it as a harbinger of tolerance and the only ethical and epistemic stance worthy of the open-minded and tolerant. Detractors dismiss it for its alleged incoherence and uncritical intellectual permissiveness. Debates about relativism permeate the whole spectrum of philosophical sub-disciplines. From ethics to epistemology, science to religion, political theory to ontology, theories of meaning and even logic, philosophy has felt the need to respond to this heady and seemingly subversive idea. Discussions of relativism often also invoke considerations relevant to the very nature and methodology of philosophy and to the division between the so-called ‘analytic and continental’ camps in philosophy. And yet, despite a long history of debate going back to Plato and a still developing large body of writing, it is still difficult to come to an agreed definition of what, at its core, relativism is, and what philosophical import it has. This entry attempts to provide a broad account of the many ways in which ‘relativism’ has been defined, explained, defended and criticized. (shrink)

The particular behavior exhibited by sentences featuring predicates of personal taste such as “tasty” may drive us to claim that their truth depends on the context of assessment, as MacFarlane does. MacFarlane considers two ways in which the truth of a sentence can depend on the context of assessment. On the one hand, we can say that the sentence expresses a proposition whose truth-value depends on the context of assessment. This is MacFarlane’s position, which he calls “truth relativism” and, following (...) Weatherson, I rebrand as “nonindexical relativism”. On the other hand, we can say that what proposition a sentence expresses depends on the context of assessment. MacFarlane calls this position “content relativism” and rejects it on the grounds that it leads to implausible readings of certain sentences and is unable to account for the speaker’s authority over the content of her assertions. In this paper, I too argue against content relativism, which, again following Weatherson, I rebrand as “indexical relativism”. However, my arguments against the theory are different from MacFarlane’s, which I prove unsound. In particular, I show that any version of indexical relativism will be unable to account for at least one of the phenomena that have been standardly used to motivate nonindexical relativism—faultless disagreement and retraction—in most of the ways in which it has been proposed to understand them.

This opinionated survey article discusses a relativist view in metaethics that we can call Appraiser-standard Relativism. According to this view, the truth value of moral judgments varies depending on the moral standard of the appraiser – that is, someone who makes or assesses the judgments. On this view, when two persons judge that, say, lying is always morally wrong; one of the judgments might be true and the other false. The paper presents various forms of this view, contrasts it against (...) other forms of moral relativism, and shortly describes the main arguments for it. It considers the two most pressing objections – from disagreement and from counterintuitivity – and discusses how different forms of Appraiser-standard Relativism are affected by, or can be seen as responses to, these objections. Lastly, it discusses whether Appraiser-standard Relativism rules out moral realism, the view that there are objective moral truths. (shrink)

The ability to compare possibilities and designate some as ‘better’ than others is a fundamental aspect of our use of modals and propositional attitude verbs. This article aims to support a proposal by Sloman that certain modal expressions, in particular, ought, in fact have a more pronounced comparative backbone than others . The connection between ‘ought’ and ‘better’ is supported by linguistic data and a proposal is advanced for modeling ideals in a way that makes room for non-comparative, strong, priority-type (...) necessity.

Contextualism about many expressions faces a common objection: in some discourses it appears that there is no single interpretation which can explain how a speaker is justified in making her assertion and how a hearer with different information or standards is justified in negatively evaluating what the speaker said. According to the Multiple Proposition Strategy , contextualists may attempt to explain these competing features pragmatically in terms of different propositions in play. In this paper I argue against the Multiple Proposition (...) Strategy, first focusing on epistemic modals and then generalising the results to other expressions. I show how when purportedly contextualist terms are embedded in belief reports, we get similar problems but that the Multiple Proposition Strategy does not provide a satisfactory explanation of such cases. I suggest, therefore, that we reject the Multiple Proposition Strategy in favour of a theory that explains the unembedded and embedded cases in similar ways. (shrink)

I argue for the possibility of substantive aesthetic disagreements in which both parties speak truly. The possibility of such disputes undermines an argument mobilized by relativists such as Lasersohn (Linguist Philos 28:643–686, 2005) and MacFarlane (Philos Stud 132:17–31, 2007) against contextualism about aesthetic terminology. In describing the facts of aesthetic disagreement, I distinguish between the intuition of dispute on the one hand and the felicity of denial on the other. Considered separately, neither of those phenomena requires that there be a (...) single proposition asserted by one party to an aesthetic dispute and denied by the other. I suggest instead that many such disputes be analyzed as disputes over the selection or appropriateness of a contextually salient aesthetic standard. (shrink)

Subjective language has attracted substantial attention in the recent literature in formal semantics and philosophy of language Subjective meaning: alternatives to relativism, De Gruyter, Berlin, pp 1–19, 2016; Lasersohn in Subjectivity and perspective in truth-theoretic semantics, Oxford University Press, Oxford, 2017; Vardomskaya in Sources of subjectivity, Ph.D. thesis, University of Chicago, IL, 2018; Zakkou in Faultless disagreement: a defense of contextualism in the realm of personal taste, Vittorio Klostermann, Frankfurt a. M., 2019b). Most current theories argue that Subjective Predicates, which (...) express matters of opinion, semantically differ from ordinary predicates, which express matters of fact. We will call this view “SP exceptionalism”. This paper addresses SP exceptionalism by scrutinizing the behavior of SPs in attitude reports, which, as we will argue, significantly constrains the space of analytical options and rules out some of the existing theories. As first noticed by Stephenson :487–525, 2007a; Towards a theory of subjective meaning, Ph.D. thesis, Massachusetts Institute of Technology, Cambridge, MA, 2007b), the most prominent reading of embedded SPs is one where they talk about the attitude holder’s subjective judgment. As is remarked sometimes :327–352, 2009; Pearson in J Semant 30:103–154, 2013a), this reading is not the only one: embedded SPs may also talk about someone else’s, non-local, judgment. We concentrate specifically on such cases and show that non-local judgment is possible if and only if SPs are used within a DP that is outside main predicate position and that entire DP is read de re. We demonstrate that the behavior of SPs in attitude reports does not differ from that of ordinary predicates: it follows from general constraints on intersective modification and intensional quantification Ways of scope taking, Springer, Dordrecht, pp 183–215, 1997; Musan in On the temporal interpretation of noun phrases, Garland, New York, 1997; Percus in Nat Lang Semant 8:173–229, 2000; Keshet in Good intensions: paving two roads to a theory of the de re/de dicto distinction, Ph.D. thesis, Massachusetts Institute of Technology, Cambridge, MA, 2008). We argue that this unexceptional behavior of SPs in fact has unexpected consequences for SP exceptionalism. Precisely because SPs have been argued to be semantically different from ordinary predicates, not all theories correctly predict these less-studied data: some overgenerate :691–706, 2007; Sæbø 2009) and some undergenerate Proceedings of Sinn und Bedeutung, vol 11, pp 433–447, 2007; Pearson 2013a). Out of the currently available theories, only relativist accounts :643–686, 2005; MacFarlane 2014; Bylinina in J Semant 34, 291–331, 2017; Coppock in Linguist Philos 41:125–164, 2018) predict the right interpretation, and only that interpretation. We thus present a novel empirical argument for relativism, and, more generally, formulate a constraint that has to be taken into consideration by any view that advocates SP exceptionalism. (shrink)

The morphological marking that distinguishes conditionals that are called “counterfactual” from those that are not, can also be found in other modal constructions, such as in the expression of wishes and oughts. We propose to call it “X-marking”. In this article, we lay out desiderata for a successful theory of X-marking and make some initial informal observations. Much remains to be done.

The most basic argument for moral relativism is that different people are (fundamentally) disposed to apply moral terms, such as ‘morally right’ and ‘morally wrong’, and the corresponding concepts, to different (types of) acts. In this paper, I argue that the standard forms of moral relativism fail to account for certain instances of fundamental variation, namely, variation in metaethical intuitions, and I develop a form of relativism—pluralism—that does account for them. I identify two challenges that pluralism faces. To answer the (...) challenges, I first argue that, due to fundamental conceptual variations in ordinary descriptive (nonmoral) discourse, a form of pluralism holds there as well and that this pluralism can answer the corresponding challenges. I then argue that the answers transfer to moral discourse, since the phenomenon of moral variation is structurally identical to that of descriptive variation. (shrink)

ABSTRACT Natural language semantics is heir to two formalisms. There is the extensional machinery of explicit variables traditionally used to model reference to individuals, and the intensional machinery of implicit index parameters traditionally used to model reference to worlds and times. I propose instead a simple and unified extensional formalism – explicit semantics – on which all sentences include explicit individual, world and time variables. No implicit index parameters are needed.

Content- relativism is a semantic theory that states that the content of an uttered sentence can vary according to some feature of an assessment context. This paper has two objectives. The first is to determine which features a motivational case for content- relativism would display – what would a good case for content- relativism look like? The second is to consider cases that appear to have the required features and evaluate their prospects as motivational cases. I identify two varieties of (...) motivational case for content- relativism : content interpretation and content enhancement. I conclude that only content enhancement cases are likely to motivate content- relativism. (shrink)
