In a recent book (_Lying and insincerity_, Oxford University Press, 2018), Andreas Stokke argues that one lies iff one says something one believes to be false, thereby proposing that it becomes common ground. This paper shows that Stokke’s proposal is unable to draw the right distinctions about insincere performative utterances. The objection also has repercussions on theories of assertion, because it poses a novel challenge to any attempt to define assertion as a proposal to update the common ground.

The paper confronts the disagreement argument for relativism about matters of taste, defending a specific form of contextualism. It is first considered whether the disagreement data might manifest an inviariantist attitude speakers pre-reflectively have. Semantic and ontological enlightenment should then make the impressions of disagreement vanish, or at least leave them as lingering ineffectual Müller-Lyer-like illusions; but it is granted to relativists that this does not fully happen. López de Sa’s appeal to presuppositions of commonality and Sundell’s appeal to metalinguistic (...) disagreement are discussed, and it is argued that, although they help to clarify the issues, they do not fully explain why such impressions remain under enlightenment. To do it, the paper develops a suggestion that other writers have made, that the lingering impression of disagreement is a consequence of a practical conflict, appealing to dispositions to practical coordination that come together with presuppositions of commonality in axiological matters.

There is a difference between the conditions in which one can felicitously use a ‘must’-claim like and those in which one can use the corresponding claim without the ‘must’, as in 'It must be raining out' versus 'It is raining out. It is difficult to pin down just what this difference amounts to. And it is difficult to account for this difference, since assertions of 'Must p' and assertions of p alone seem to have the same basic goal: namely, communicating (...) that p is true. In this paper I give a new account of the conversational role of ‘must’. I begin by arguing that a ‘must’-claim is felicitous only if there is a shared argument for the proposition it embeds. I then argue that this generalization, which I call Support, can explain the more familiar generalization that ‘must’-claims are felicitous only if the speaker’s evidence for them is in some sense indirect. Finally, I propose a pragmatic derivation of Support as a manner implicature. (shrink)

Is the mechanism behind presupposition projection and filtering fundamentally asymmetric or symmetric? This is a foundational question for the theory of presupposition which has been at the centre of attention in recent literature :287–316, 2008b. https://doi.org/10.1515/THLI.2008.021, Semant Pragmat 2:1–78, 2009. https://doi.org/10.3765/sp.2.3; Rothschild in Semant Pragmat 4:1–43, 2011/2015. https://doi.org/10.3765/sp.4.3 a.o.). It also bears on broader issues concerning the source of asymmetries observed in natural language: are these simply rooted in superficial asymmetries of language use ; or are they, at least in (...) part, directly encoded in linguistic knowledge and representations? In this paper we aim to make progress on these questions by exploring presupposition projection across conjunction, which has traditionally been taken as a central piece of evidence that presupposition filtering is asymmetric in general. As a number of authors have recently pointed out, however, the evidence which has typically been used to support this conclusion is muddied by independent issues concerning redundancy; additional concerns have to do with the possibility of local accommodation. We report on a series of experiments, building on previous work by Chemla and Schlenker :177–226, 2012. https://doi.org/10.1007/s11050-012-9080-7) and Schwarz Experimental perspectives on presuppositions, Springer, Cham, 2015), using inference and acceptability tasks, which aim to control for both of these potential confounds. In our results, we find strong evidence for left-to-right filtering across conjunctions, but no evidence for right-to-left filtering—even when right-to-left filtering would, if available, rescue an otherwise unacceptable sentence. These results suggest that presupposition filtering across conjunction is asymmetric, contra suggestions in the recent literature :157–212, 2008a. https://doi.org/10.1515/THLI.2008.013, 2009 a.o.), and pave the way for the investigation of further questions about the nature of this asymmetry and presupposition projection more generally. Our results also have broader implications for the study of presupposition: we find important differences in the verdicts of acceptability versus inference tasks in testing for projected content, which has both methodological ramifications for the question of how to distinguish presupposed content, and theoretical repercussions for understanding the nature of projection and presuppositions more generally.

The meaning of definite descriptions (like ‘the King of France’, ‘the girl’, etc.) has been a central topic in philosophy and linguistics for the past century. Indefinites (‘Something is on the floor’, ‘A child sat down’, etc.) have been relatively neglected in philosophy, under the Russellian assumption that they can be unproblematically treated as existential quantifiers. However, an important tradition, drawing from Stoic logic, has pointed to patterns which suggest that indefinites cannot be treated simply as existential quantifiers. The standard (...) dynamic semantic treatment of those phenomena, however, has well-known problems with negation and disjunction. -/- In this paper I develop a new approach to (in)definites. On my theory, truth-conditions are classical. But in addition to truth-conditions, meanings comprise a second dimension of what I call bounds. It is at the level of bounds, not truth-conditions, that I locate the characteristically dynamic coordination between indefinites and definites. The resulting system thus has a classical logic. This approach avoids dynamic semantics’ logical problems, and, more generally, yields a new perspective on the relation between truth-conditional and dynamic effects in natural language. (shrink)

The Identity principle says that conditionals with the form 'If p, then p' are logical truths. Identity is overwhelmingly plausible, and has rarely been explicitly challenged. But a wide range of conditionals nonetheless invalidate it. I explain the problem, and argue that the culprit is the principle known as Import-Export, which we must thus reject. I then explore how we can reject Import-Export in a way that still makes sense of the intuitions that support it, arguing that the differences between (...) indicative and subjunctive conditionals play a key role in solving this puzzle.

There has been recent interest in the idea that speakers who appear to be having a verbal dispute may in fact be engaged in a metalinguistic negotiation: they are communicating information about how they believe an expression should be used. For example, individuals involved in a dispute about whether a racehorse is an athlete might be communicating their diverging views about how ‘athlete’ should be used. While many have argued that metalinguistic negotiation is a pervasive feature of philosophical and everyday (...) discourse, the literature currently lacks an account of this phenomenon that can be situated within a ‘mainstream’ view of communication. I propose an independently motivated account where individuals reconstruct metalinguistic propositions by means of a pragmatic, Gricean reasoning process. (shrink)

Compare the following conditionals: 'If John is not in Paris, he is in France' versus 'If John is in France, he is not in Paris.' The second sounds entirely natural, whereas the first sounds quite strange. This contrast is puzzling, because these two conditionals have the same structure at a certain level of logical abstraction, namely 'If ¬p+, then p.' -/- We argue that existing theories of informational oddness do not distinguish between these conditionals. We do not have an account (...) of the divergence in judgments about the two, but we think this is a fascinating puzzle which we pose here in the hope others will be able to solve it. (shrink)

We consider question-answer dialogues between participants who may disagree with each other. The main problems are: (a) How different speech-acts affect the information in the dialogue; and (b) How to represent what was said in a dialogue, so that we can summarize it even when it involves disagreements (i.e., inconsistencies).We use a fully-typed many-sorted language L with a possible-worlds semantics. L contains nominals representing short answers. The speech-acts are uniformly represented in a dialogue language DL by focus structures, consisting of (...) a mood operator, a topic component and a focus component. Each stage of the dialogue is associated with a set of information functions (g-functions), which are partial functions taking a topic component (representing a question raised) to a set of propositions determined by the corresponding focus component (to the set of answers given to it). (shrink)

Natural dialogue does not proceed haphazardly; it has an easily recognized “episodic” structure and coherence which conform to a well developed set of conventions. This paper represents these conventions formally in terms related to speech act theory and to a theory of action.The major formal unit, the dialogue game, specifies aspects of the communication of both participants in a dialogue. We define the formal notion of dialogue games, and describe some of the important games of English. Dialogue games are conventions (...) of interactive goal pursuit. Using them, each participant pursues his own goals in a way which sometimes serves the goals of the other. The idea of dialogue games can thus be seen as a part of a broader theoretical perspective which characterizes virtually all communication as goal pursuit activity.We also define and exemplify the property of Motivational Coherence of dialogues. Motivational Coherence can be used as an interpretive principle in explaining language comprehension.Actual dialogue games have a kind of causal connectedness which is not a consequence of their formal properties. This is explained in terms of a theory of action, which is also seen to explain a similar attribute of speech acts. (shrink)

Linguistics and philosophy have provided distinct views on the nature of reference to individuals in language. In philosophy, in particular in the tradition of direct reference, the distinction is between reference and description. In linguistics, in particular in the tradition of generative grammar, the distinction is between pronouns and R-expressions. I argue for a third conception, grounded in dynamic semantics, in which the main watershed is between definites, which trigger presuppositions that want to be bound, and indefinites, which set up (...) new discourse referents. On this view, proper names, indexicals, and definite descriptions are all analyzed as presupposition triggers. (shrink)

This paper motivates and explores an expressivist theory of vagueness, modelled on Allan Gibbard’s normative expressivism. It shows how Chris Kennedy’s semantics for gradable adjectives can be adjusted to fit into a theory on Gibbardian lines, where assertions constrain not just possible worlds but plans for action. Vagueness, on this account, is literally indecision about where to draw lines. It is argued that the distinctive phenomena of vagueness, such as the intuition of tolerance, can be explained in terms of practical (...) constraints on plans, and that the expressivist view captures what is right about several contending theories of vagueness.

Philippe Schlenker gives a method of deriving local contexts from an expression’s classical semantics. In this paper I show that this method, when applied to the traditional variably strict semantics for subjunctive conditionals of Robert Stalnaker, David Lewis, and Angelika Kratzer, delivers an empirically incorrect prediction. The prediction is that the antecedent of a conditional should have the whole domain of possible worlds as its local context and therefore should be allowed to have only necessary presuppositions. In the later part (...) of the paper, I suggest the outlines of a solution to the problem. The solution involves adding a shifting contextual restriction on the domain of possible worlds. (shrink)

The ‘indispensability argument’ for the existence of mathematical objects appeals to the role mathematics plays in science. In a series of publications, Joseph Melia has offered a distinctive reply to the indispensability argument. The purpose of this paper is to clarify Melia’s response to the indispensability argument and to advise Melia and his critics on how best to carry forward the debate. We will begin by presenting Melia’s response and diagnosing some recent misunderstandings of it. Then we will discuss four (...) avenues for replying to Melia. We will argue that the three replies pursued in the literature so far are unpromising. We will then propose one new reply that is much more powerful, and—in the light of this—advise participants in the debate where to focus their energies. (shrink)

Context-sensitivity raises a metasemantic question: what determines the value of a context-sensitive expression in context? Taking gradable adjectives as a case study, this paper argues against various forms of intentionalist metasemantics, i.e. that speaker intentions determine values for context-sensitive expressions in context, including the coordination account recently defended by King :219–237, 2014a; in: Burgess, Sherman Metasemantics: New essays on the foundations of meaning, Oxford University Press, Oxford, pp 97–118, 2014b). The paper argues that all intentionalist accounts face the speaker authority (...) problem, that speaker intentions are just the wrong sorts of things to determine the standards for gradable adjectives in context. The problem comes to light when we look at cases in which speakers have idiosyncratic, false beliefs that cause their proper communicative intentions to come apart from the non-intentional features of context like the question under discussion, facts about the world, practical goals, and prior linguistic discourse.

Discourse dynamics, pragmatics, and indefinites Content Type Journal Article Pages 1-30 DOI 10.1007/s11098-012-9882-y Authors Karen S. Lewis, Department of Philosophy, University of Southern California, Los Angeles, CA, USA Journal Philosophical Studies Online ISSN 1573-0883 Print ISSN 0031-8116.

One of the central questions of discourse dynamics is when an anaphoric pronoun is licensed. This paper addresses this question as it pertains to the complex data involving anaphora and negation. It is commonly held that negation blocks anaphoric potential, for example, we cannot say “Bill doesn’t have a car. It is black”. However, there are many exceptions to this generalization. This paper examines a variety of types of discourses in which anaphora on indefinites under the scope of negation is (...) felicitous. These cases are not just of intrinsic interest, but I argue present serious problems for the dynamic semantic framework, which builds the licensing facts into the semantics. I argue in favor of adopting a dynamic pragmatics, a theory that explains context change through general Gricean principles, and combining it with a static, d-type theory of anaphora, in which pronouns go proxy for definite descriptions.

The commonplace view about metaphorical interpretation is that it can be characterized in traditional semantic and pragmatic terms, thereby assimilating metaphor to other familiar uses of language. We will reject this view, and propose in its place the view that, though metaphors can issue in distinctive cognitive and discourse effects, they do so without issuing in metaphorical meaning and truth, and so, without metaphorical communication. Our inspiration derives from Donald Davidson’s critical arguments against metaphorical meaning and Richard Rorty’s exploration of (...) the diverse uses of language. But unlike these authors we ground our discussion squarely in distinctions about causal mechanisms in cooperative activity developed by H.P. Grice and others. (shrink)

In this paper, I show that, given seemingly plausible assumptions about the epistemic ‘might’ and conditionals, we cannot explain why in some circumstances it is appropriate to utter conditional ‘might’-sentences, like “If Angelica has crumbs in her pocket, then she might be the thief” and not the corresponding simple ones, like “Angelica might be the thief.” So, one of our assumptions must be incorrect. I argue that the root of the problem is an umbrella thesis about the pragmatics of ‘might’-communication (...) - one that says that the communicative impact of an utterance of a ‘might’-sentence is the performance of a consistency check on the information of the context. I conclude that we must reject this thesis. And I close the paper by sketching an alternative view about what assertive uses of ‘might’-sentences typically do - one which avoids the problem. Such uses typically present a possibility as a serious option in reasoning and deliberation. (shrink)

The standard versions of predicativism are committed to the following two theses: proper names are count nouns in all their occurrences, and names do not refer to objects but express name-bearing properties. The main motivation for predicativism is to provide a uniform explanation of referential names and predicative names. According to predicativism, predicative names are fundamental and referential names are explained by appealing to a null determiner functioning like “the” or “that.” This paper has two goals. The first is to (...) reject the predicativists’ explanation of the two types of names. I present three syntactic counterexamples to the predicativists’ account of referential names: incorporation, modification, and measure phrase uses. The second goal is to present a novel strategy to explain the two types of names. I propose that referential names are fundamental but that there are null morphemes available for transforming a name into a count noun (and possibly into other syntactic categories). (shrink)

This paper consists of two sections: first, I return to the question of precisely which contextual factors are at work in metaphorical interpretation, and of the relation between asserted, presupposed and implied information; the upshot of this will be a renewed emphasis on metaphor as a discourse phenomenon. Second, I sketch a preliminary argument as to what a social practice account of metaphor might look like. Recent explorations of the contextual factors involved in the interpretation ofmetaphor make crucial use of (...) David Kaplan’s Logic of Demonstratives, with its sophisticated treatment of context-dependence, and of the work on assertion developed by Stalnaker and others. All these approaches take contextual factors or parameters like that of speaker, time and place of utterance, etc., as given or primitive. Recent anthropological research, however, suggests that our practices constitute not only the contents of our utterances but also their contexts. Another recent development in linguistic anthropology is an increased attention to so-called language ideologies or metalinguistic beliefs, i.e., folk theories about the character and functioning of language. These insights suggest that metaphor is so thoroughly dependent on variable contextual and metalinguistic factors that it may well dissolve as a natural kind. At the very least, they suggest a shift away from the view of metaphor as a decontextualized sentence- or utterance-level phenomenon occurring in literate practices, which is still tacitly assumed in much literature on the topic.

Scalar implicatures arise when a speaker uses a logically weak alternative in a context where a logically stronger alternative was available. Presuppositional implicatures, as I call them, arise when a speaker uses a presuppositionally weak alternative when a presuppositionally stronger alternative was available. My goal is to give a detailed, working theory of presuppositional implicatures, and show that they are a special case of scalar implicatures. In doing so, I carefully contrast presuppositional implicatures with antipresuppositions. These two phenomena have been (...) treated as closely related in the literature, but some differences have not been adequately appreciated. Antipresuppositions are observed when a presuppositionally weak alternative is infelicitously used in a context that satisfies the presupposition of a presuppositionally stronger alternative. Presuppositional implicatures arise when a presuppositionally weak alternative is felicitously used in a context that does not satisfy the presupposition of a presuppositionally stronger alternative, but where that stronger presupposition would have been accommodated. Attention to this difference reveals a shortcoming in Schlenker’s theory of presuppositional implicature. This paper both identifies and remedies that shortcoming. (shrink)

This paper argues that truth values of sentences containing predicates of “personal taste” such as fun or tasty must be relativized to individuals. This relativization is of truth value only, and does not involve a relativization of semantic content: If you say roller coasters are fun, and I say they are not, I am negating the same content which you assert, and directly contradicting you. Nonetheless, both our utterances can be true (relative to their separate contexts). A formal semantic theory (...) is presented which gives this result by introducing an individual index, analogous to the world and time indices commonly used, and by treating the pragmatic context as supplying a particular value for this index. The context supplies this value in the derivation of truth values from content, not in the derivation of content from character. Predicates of personal taste therefore display a kind of contextual variation in interpretation which is unlike the familiar variation exhibited by pronouns and other indexicals. (shrink)

We derive a probabilistic account of the vagueness and context-sensitivity of scalar adjectives from a Bayesian approach to communication and interpretation. We describe an iterated-reasoning architecture for pragmatic interpretation and illustrate it with a simple scalar implicature example. We then show how to enrich the apparatus to handle pragmatic reasoning about the values of free variables, explore its predictions about the interpretation of scalar adjectives, and show how this model implements Edgington’s Vagueness: a reader, 1997) account of the sorites paradox, (...) with variations. The Bayesian approach has a number of explanatory virtues: in particular, it does not require any special-purpose machinery for handling vagueness, and it is integrated with a promising new approach to pragmatics and other areas of cognitive science.

Kaplan (1977) proposes a neo-Fregean theory of demonstratives which, despite its departure from a certain problematic Fregean thesis, I argue, ultimately founders on account of its failure to give up the Fregean desideratum of a semantic theory that it provide an account of cognitive significance. I explain why Kaplan's (1989) afterthoughts don't remedy this defect. Finally, I sketch an alternative nonsolipsistic picture of demonstrative reference which idealizes away from an agent's narrowly characterizable psychological state, and instead relies on the robust (...) multiply realizable relation between the skilled agent and demonstrated object.When the unclean spirit has gone out of a person, it wanders through waterless regions looking for a resting place, but it finds none. Then it says, 'I will return to my house from which I came.' When it comes, it finds it empty, swept, and put in order. Then it goes and brings along seven other spirits more evil than itself, and they enter and live there; and the last state of that person is worse than the first. So will it be also with this evil generation. (shrink)

John Searle has argued that all perceptual experiences are token-reflexive, in the sense that they are constituents of their own veridicality conditions. Many philosophers have found the kind of token-reflexivity he attributes to experiences, which I will call _causal_ token-reflexivity, unfaithful to perceptual phenomenology. In this paper, I develop an argument for a different sort of token-reflexivity in perceptual (as well as some non- perceptual) experiences, which I will call _temporal_ token-reflexivity, and which ought to be phenomenologically unobjectionable.

Plural definite descriptions across many languages display two well-known properties. First, they can give rise to so-called non-maximal readings, in the sense that they ‘allow for exceptions’. Second, while they tend to have a quasi-universal quantificational force in affirmative sentences, they tend to be interpreted existentially in the scope of negation. Building on previous works, we offer a theory in which sentences containing plural definite expressions trigger a family of possible interpretations, and where general principles of language use account for (...) their interpretation in various contexts and syntactic environments. Our theory solves a number of problems that these previous works encounter, and has broader empirical coverage in that it offers a precise analysis for sentences that display complex interactions between plural definites, quantifiers and bound variables, as well as for cases involving non-distributive predicates. The resulting proposal is briefly compared with an alternative proposal by Križ, which has similar coverage but is based on a very different architecture and sometimes makes subtly different predictions.

Along with many other languages, English has a relatively straightforward grammatical distinction between mass-occurrences of nouns and their countoccurrences. As the mass-count distinction, in my view, is best drawn between occurrences of expressions, rather than expressions themselves, it becomes important that there be some rule-governed way of classifying a given noun-occurrence into mass or count. The project of classifying noun-occurrences is the topic of Section II of this paper. Section III, the remainder of the paper, concerns the semantic differences between (...) nouns in their mass-occurrences and those in their count-occurrences. As both the name view and the mixed view are, in my opinion, subject to serious difficulties discussed in Section III.1,I defend a version of the predicate view. Traditionally, nouns in their singular count-occurrences are also analyzed as playing the semantic role of a predicate. How, then, does the predicate view preserve the intuitive difference between nouns in their mass- and those in their count-occurrences? I suggest, in Section III.2, that there are different kinds of predicates: mass-predicates, e.g. ‘is hair’, singular count-predicates, e.g. ‘is a hair’, and plural count-predicates, e.g. ‘are hairs’. Mass-predicates and count-predicates, in my view, are not reducible to each other. The remainder of Section III takes a closer look at the differences and interrelations between these different kinds of predicates. Mass-predicates and count-predicates differ from each other truth-conditionally, and these truth-conditional differences turn out to have interesting implications, in particular concerning the part-whole relation and our practices of counting. But mass- and count-predicates are also related to each other through systematic entailment relations; these entailment relations are examined in Section III.4. (shrink)

This paper argues for a largely unnoted distinction between relational and modal components in the lexical semantics of verbs. Wehypothesize that many verbs encode two kinds of semantic information:a relationship among participants in a situation and a subset ofcircumstances or time indices at which this relationship isevaluated. The latter we term sublexical modality.We show that linking regularities between semantic arguments andsyntactic functions provide corroborating evidence in favor of thissemantic distinction, noting cases in which the semantic groundingof linking through participant-role properties (...) apparently fails. Thissemantic grounding can be preserved, however, once we abstractaway from sublexical modality in lexical semantic representations.Semantically-based linking constraints are insensitive to the sublexicalmodality component of lexical entries and depend only on informationin a predicator's situational core.

We develop and defend a new approach to counterlogicals. Non-vacuous counterlogicals, we argue, fall within a broader class of counterfactuals known as counterconventionals. Existing semantics for counterconventionals, 459–482 ) and, 1–27 ) allow counterfactuals to shift the interpretation of predicates and relations. We extend these theories to counterlogicals by allowing counterfactuals to shift the interpretation of logical vocabulary. This yields an elegant semantics for counterlogicals that avoids problems with the usual impossible worlds semantics. We conclude by showing how this approach (...) can be extended to counterpossibles more generally. (shrink)

I distinguish two notions of agreement in belief: believing the same content versus having beliefs that necessarily coincide/diverge in normative status. The second notion of agreement,, is clearly significant for the communication of beliefs amongst thinkers. Thus there would seem to be some prima facie advantage to choosing the conception of content operative in in such a way that the normative status of beliefs supervenes on their content, and this seems to be the prevailing assumption of many semanticists. I shall (...) argue that de se beliefs and assertions provide a motivation to depart from this assumption, and so do beliefs and assertions concerning what is epistemically possible. I conclude by offering two models of assertoric communication that are compatible with the abandonment of the assumption, and suggesting schematically that each model applies to different cases. (shrink)

Some philosophers, for example David Lewis, have argued for the need to introduce de se contents or centered contents, i.e. contents of thought and speech the correctness of believing which depends not only on the possible world one inhabits, but also on the location one occupies. Independently, philosophers like Robert Stalnaker (and also David Lewis) have developed the conversational score model of linguistic communication. This conversational model usually relies on a more standard conception of content according to which the correctness (...) of believing a content depends merely on the possible world one occupies. The aim of this paper is to develop a modified conversational score model that operates with centered contents. I begin by explaining how in principle centered contents can figure in the transfer of information from one thinker to another. Here I distinguish the local portability approach from the portable surrogate approach. Then I explain how these modes of information transfer can be exploited in a stalnakerian conversational model involving centered contents, proposing a modified update rule for assertion. (shrink)

Horizontalism is the thesis that what a speaker asserts in literally and sincerely uttering an indicative sentence is some horizontal proposition of her utterance; diagonalism is the thesis that what a speaker asserts in literally and sincerely uttering an indicative sentence is some diagonal proposition of her utterance. Recent work on assertion has reached no clear consensus favoring either horizontalism or diagonalism. I explore a novel strategy for adjudicating between the two views by considering the advantages and disadvantages which would (...) accrue to a linguistic community as a result of adopting different committal practices—that is, practices of associating utterances with the propositions to which speakers undertake assertoric commitments in uttering them—ultimately concluding that a horizontalist practice has important advantages over its competitors. (shrink)

In this paper, I argue that, contrary to Robert Stalnaker’s highly influential account of linguistic communication, successful communication does not depend on a common ground between speaker and hearer. The problem for Stalnaker’s account manifests itself in communicative situations that represent both Lingens cases, i.e., cases involving egocentric beliefs, and Frege cases, i.e., cases involving identity confusions. I describe two hypothetical cases that involve successful communication, but in which no common ground of the kind required by Stalnaker’s account is available. (...) I therefore propose an alternative account of communication that is based on epistemic two-dimensionalism. This account maintains that communication requires the transfer of a thought content from speaker to hearer. By holding that this shared content often constitutes common ground, it preserves much of the appeal of Stalnaker’s account. However, my account allows for cases in which the shared thought content does not figure in common ground. (shrink)

It has long been known that the popular account of egocentric thoughts developed by David Lewis is in conflict with a natural account of communication, according to which successful communication requires the transmission of a thought content from speaker to hearer. In this paper, I discuss a number of proposed attempts to reconcile these two accounts of egocentric thought and communication. Each of them postulates two kinds of mental content, where one is egocentric, and the other is transmitted from speaker (...) to hearer in communication. I argue that Ninan’s account, which involves multi-centered contents, and Kölbel’s and Moss’s accounts, which postulate centered and uncentered proxy contents, respectively, are unsatisfactory. Therefore, I propose a two-dimensionalist account, according to which egocentric thoughts are represented by primary intensions, while the thoughts shared by speaker and hearer in cases of successful communication are represented by secondary intensions. Finally, I argue that aside from being able to reconcile Lewis’s account of egocentric thoughts with the natural account of communication, two-dimensionalism also provides the means for modeling agreement and disagreement.

ABSTRACT. The received picture of linguistic communication understands communication as the transmission of information from speaker's head to hearer's head. This picture is in conflict with the attractive Lewisian view of belief as self-location, which is motivated by de se attitudes – first-personal attitudes about oneself – as well as attitudes about subjective matters such as personal taste. In this paper, I provide a solution to the conflict that reconciles these views. I argue for an account of mental attitudes and (...) communication on which mental content and speech act content is understood as sets of multicentered worlds – roughly, possible worlds ‘centered’ on a sequence of individuals at a time. I develop a Stalnakerian model of communication based on multicentered worlds content, and I provide a suitable semantics for personal pronouns and predicates of personal taste. The resulting picture is one on which the point of conversation is the coordination of individual perspectives. (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)

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)

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.

Drawing on recent work in formal pragmatic theory, this paper shows that the manipulation of discourse structure—in particular, by way of shifting the Question Under Discussion mid-discourse—can constitute an act of epistemic injustice. I argue that the “All Lives Matter” response to the “Black Lives Matter” slogan is one such case; this response shifts the Question Under Discussion governing the overarching discourse from Do Black lives matter? to Which lives matter? This manipulation of the discourse structure systematically obscures the intended (...) meaning of “Black lives matter” and disincentivizes future utterances of it. (shrink)
