This chapter offers a synoptic survey of work on the discourse dynamics of vague language. It starts by briefly introduction to the traditional philosophical puzzles of vagueness, to do with indeterminacy and tolerance. From there, it turns to evidence that vague language exhibits nontrivial discourse dynamics. Different approaches to the discourse dynamics of vagueness are taxonomized and critically evaluated. The chapter concludes by considering the prospects of leveraging an account of the dynamics of vague language to provide a solution to the traditional puzzles of vagueness.

We examine a previously undiscussed interaction between tense and predicates of personal taste (PPTs). While disagreements involving delicious or fun are generally considered faultless – they have no clear fact of the matter – we observe that, in joint oral narratives, this faultlessness varies with tense: if the narrative is told in the historical present, disagreements involving a PPT are not faultless. Drawing on narrative research in psychology and discourse analysis, we propose that this contrast reflects a pragmatic convention of the narrative genre that participants construct a consensus version of what happened from a unitary perspective. To link this pragmatics with the semantics, we adopt a bicontextual semantics, where the perspectival parameters for both PPTs and tense are located in a context of assessment (and not context of utterance). We show that when these contextual parameters are constrained by the unitary perspective of narratives, the present tense leads to nonfaultless disagreements, as its semantics tightly binds the temporal location of an event to the parameter relevant for appraisal. The past tense, by contrast, enables both faultless and nonfaultless disagreements. We derive this flexibility by revising the existing semantics for past tense, engendering a new perspective on crosslinguistic variation in tense usage.

We defend an acquaintance-based semantics for ‘de re’ attitude reports. We begin by surveying the philosophical literature on the logical form of the ‘de re’, with particular attention to how acquaintance relations solve the problem posed by so-called double vision scenarios. We reject the view that cognitive contact with the ‘res’ requires causal interaction: the causal conception of acquaintance is inadequately motivated in the philosophical literature on the ‘de re’. We then turn to other linguistic data. We show that the ‘de re’ analysis is needed to account for certain tense constructions. The success of this application provides a further reason to reject an exclusively causal conception of acquaintance, since the kind of cognitive contact relevant to ‘de re’ attitudes towards times cannot plausibly be causal. We discuss objections to the ‘de re’ analysis of tense, such as the apparent unavailability of double vision scenarios involving times. We consider various additional principles and constraints that further refine the theory’s predictions, and conclude that while further research is needed to fully vindicate the ‘de re’ analysis in this application, it offers the most unified and well-motivated account of the embedded tense data currently on offer.

This chapter focuses on the role that discourse relations and structure play in a variety of phenomena of interest to semanticists and philosophers. Not only do discourse relations add semantic content above and beyond the individual propositions expressed by the utterances in a discourse, but they, and the complex structures to which they give rise, can influence the interpretations of individual utterances, having an effect on the very propositions the utterances are understood to express. In this chapter, we look in detail at how theories of discourse structure can be brought to bear on at-issue and non-at-issue content, using appositive relative clauses and discourse parenthetical reports as illustrations. We also discuss recent efforts to use discourse structure to model conversational goals and capture the subjective nature of discourse interpretation as well as recent work extending theories of discourse structure to multimodal discourse. Along the way, we emphasize the importance of corpus work in studying discursive phenomena and raise a series of large questions to be pursued in future work.

Definite descriptions are an area where linguistics and philosophy have been intimately intertwined as long as they have been acquainted. But are we past all that now, in the modern era, as work on definite descriptions becomes less focussed on English, and more cross-linguistic? This chapter highlights one great unresolved issue in the theory of definite descriptions that persists even in this modern era of crosslinguistic comparison, a foundational (hence philosophical) one, pitting dynamic semantics against situation semantics. A prominent synthesis of these competing (though compatible) frameworks says that both are needed, for “strong” and “weak” articles, respectively. The strong vs. weak distinction has served as inspiration for much recent work on the crosslinguistic semantics of definiteness. While this new development has led to a much richer and more well-rounded picture of definiteness as a phenomenon, the predictions of the two analyses overlap too much, leading to spurious debate when fieldworkers go to analyze a new language. The chapter aims to clarify what is at stake empirically in the choice among analyses, and advocates for continued philosophical reflection as we operationalize our methods of discovery.

The notion of ’alternative’ is central to analyses of various semantic/pragmatic phenomena, such as disjunction, focus, discourse structure, questions, and implicature. However, basic questions concerning the various notions of alternatives have not received the attention they deserve, e.g. what exactly these notions signify, or how they are supposed to interact. This chapter reflects on such questions, centering on appeals to alternatives in characterizations of focus, disjunction, discourse goals (questions under discussion), and interrogatives. More precisely, this chapter criticizes the conflation of the set of focus alternatives with the meaning of an interrogative, discusses two conceptions of the alternatives introduced by disjunction (algebraic and attention-based), and departs from the predominant view of QUDs as, essentially, linguistic questions that represent discourse goals.

This chapter looks at Donnellan’s referential–attributive distinction from a communication-theoretic perspective, which distinguishes between utterance production and utterance interpretation – in this case between the referential and the attributive use of definite descriptions and their referential and attributive interpretation. The framework is MSDRT, an extension of DRT that provides mental state descriptions (MSDs) for utterance producers and recipients. MSDs consist of propositional attitude representations (PRs) and entity representations (ERs). ERs represent entities from the outside world (their referents), to which they are linked by causal relations and which they can contribute to the contents of the agent’s PRs. The referential use and interpretation of a description are analyzed as those which producer and interpreter take to refer to the referent of one of their ERs (while the attributive use and interpretation take it to refer to whatever satisfies its descriptive content). This approach differentiates more finely between different use scenarios than other approaches and throws new light on the question whether the referential and the attributive use are mutually exclusive and whether they are jointly exhaustive.

This chapter will argue that the ontological categories that we require for understanding meaning and meaning composition in natural language cannot be exclusively proxied by external objects in the world or judgments of truth. In other words, a set of metaphysically justified ontological objects is not what is required for natural language ontology, and the latter field should be considered a distinct philosophical and analytical exercise. The chapter takes as its central empirical ground the meaning of ’nonfinite’ verb forms in English. Paradoxes relating to the English progressive and passive constructions will be examined to show that lexical conceptual content needs to be defined more essentially, and that the integration of such essentialist content into forms which ultimately have extensionalist import requires the reification of the symbol qua symbol and the explicit representation of the utterance situation.

I argue that rejection cannot be reduced to assertion. Adapting an observation by Huw Price, I argue that rejection is best conceived of as the speech act that is used to register that some other speech act is (or would be) violating a rule of the conversation game. This can be understood as registering norm violations where speech acts are characterized by their essential norms. However, rejection itself cannot be characterized by a norm. Instead, registering violations is a necessary condition for grasping the conversation game. The core observation is that the concept of an ‘illegal move’ is intelligible, so a speech act can be (say) an assertion, despite violating the essential norm of asserting. Rejection has the function of pointing out that a move is illegal. Registering rule violations is a precondition of playing games with rules (it is part of the concept ‘game’), not itself a rule in a game. A similar special role of rejection (that it is not explicable in the terms provided by a conceptual framework, but needed to grasp these terms) likely occurs in other frameworks as well, e.g. when one characterizes speech acts by commitments or their effect on a common ground.

Attitude ascriptions and speech reports were at the center of attention when philosophers and logicians began to see natural languages as formal systems. My chapter looks at the history of formal semantics, not for its own sake, but for lessons about how to approach attitude ascriptions and speech reports today. I think we may have taken a few wrong forks in the road. To solve the problem of logical equivalents, we should have listened to Rudolf Carnap, who made it clear that the fact that the truth of an attitude ascription or speech report may depend on the intensional structure of the embedded clause in no way forces the conclusion that propositions can’t be mere intensions. For de re ascriptions, we should have listened to David Kaplan, who replaced names in the scope of attitude verbs with descriptions, rather than associating the individuals those names stand for with modes of presentation. What held us back in both cases was Fregean compositionality. Shedding that legacy, I present prototypes for analyses of attitude verbs and verbs of speech within an intensional semantics where propositions are mere sets of possible worlds and de re ascriptions require no special technologies created just for them.

Modals and conditionals play a starring role in philosophical and linguistic research. The ability to think modally distal thoughts is central to the human capacity to plan and choose; and the ability to express such thoughts is central to the human capacity for collective action. Modals and conditionals have yielded a rich bounty of puzzles about logic, semantics, and pragmatics. I organize this chapter around three topics: the interpretation of epistemic modals, particularly how they interact with their local information; the interpretation of conditionals, with a focus on logical questions; and, finally, practical modality, with discussion of a potentially unified perspective on practical modality as essentially involving reference to actions.
