I attend to the debate between the A-theory of time and the B- theory of time by evaluating how each theory accounts for the possibility of change. I conclude in favour of the B-theory of time as an account of change. I begin by considering McTaggart’s argument against the reality of time. I connect McTaggart’s argument, and the attendant A-theory versus B-theory debate, to an argument against the possibility of change. This argument, the problem of change, can be refuted by (...) adopting either of an A-theory or B-theory account of change. I evaluate different approaches to change offered by various A-theories, including presentism, the growing block theory, the moving spotlight theory, and then proceed to consider different B-theory accounts of change, including relativiser endurantism, adverbialist endurantism, and perdurantism. I consider objections to each of these views. Finally, I compare the costs incurred by the best of the A-theory accounts and the best of the B-theorist accounts. (shrink)

Some theories of time entail that the present can change before or after it has happened. Examples include views on which time-travelers can change the past, the glowing block theory, Peter Geach’s mutable future view, and the moving spotlight theory. This paper argues that such ante factum or posthumous change requires a heterodox “split time” view on which earlier-than is not the converse of later-than.

The view that dominates the literature on intentional attitudes holds that beliefs and desires both have propositional content. A commitment to what I call “content uniformity” underlies this view. According to content uniformity, beliefs and desires are but different psychological modes having a uniform kind of content. Prima facie, the modes don’t place any constraint on the kinds of content the attitude can have. I challenge this consensus by pointing out an asymmetry between belief contents and desire contents which shows (...) content uniformity to be mistaken. I do this by revisiting the arguments of Richard (Philosophical Studies, 39(1): 1–13, 1981), and show that arguments which purport to show the temporal specificity of belief contents yield the opposite results for desire contents. I defend this preliminary conclusion from various strategies to neutralize the asymmetry claim. My defense provides occasions to respond to objections by Brogaard (2012) and Recanati (2007) to the Richard argument, and to get clearer on the role of temporal adjuncts in desire ascriptions. Finally, I consider whether the construal of attitude content as centered propositions (as in Lewis Philosophical Review, 88(4): 513–543, 1979) can be invoked to vindicate content uniformity. My conclusion is that while the framework itself doesn’t vindicate content uniformity, it could, but only if it availed itself of a further, substantive thesis about desire, which itself is in need of defense.

The meanings of words seem to change over time. But while there is a growing body of literature in linguistics and philosophy about meaning change, there has been little discussion about the metaphysical underpinnings of meaning change. The central aim of this paper is to push this discussion forward by surveying the terrain and advocating for a particular metaphysical picture. In so doing, we hope to clarify various aspects of the nature of meaning change, as well as prompt future philosophical (...) investigation into this topic. More specifically, this paper has two parts. The first, broadly exploratory, part surveys various metaphysical accounts of meaning change. The goal here is to lay out the terrain, thereby highlighting some key choice points. Then, in the second part, after critiquing Prosser’s (Philosophy Phenomenol Res 100(3):657–676, 2020) exdurantism about ‘mental files’, we sketch and defend the enduring senses view of meaning change.

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.

Relativism entails that sentences like ‘Liquorice is tasty’ are used to assert relativistic propositions—that is, propositions whose truth-value is relative to a taste standard. I will defend this view against two objections. According to the first objection, relativism is incompatible with a Stalnakerian account of assertion. I will show that this objection fails because Stalnakerian assertions are proposals rather than attempts to update the common ground. According to the second objection, relativism problematically predicts that we can correctly assess beliefs as (...) false but faultless. I will show that it doesn't. Such assessments come out as incorrect because correct relativistic assertion requires the absence of a presupposition of non-commonality. (shrink)

In modal logic, propositions are evaluated relative to possible worlds. A proposition may be true relative to a world w, and false relative to another world w'. Relativism is the view that the relativization idea extends beyond possible worlds and modalities. Thus, in tense logic, propositions are evaluated relative to times. A proposition (e.g. the proposition that Socrates is sitting) may be true relative to a time t, and false relative to another time t'. In this paper I discuss, and (...) attempt to rebut, two classical objections to Relativism. The first objection, due to Frege, is the objection from incompleteness. I distinguish two possible relativist responses to that objection, one of which corresponds to the view I actually defend : Moderate Relativism. The second objection is due to Mark Richard, who argued that the objects of belief cannot be relativistic. I show that that objection can be met within the Moderate Relativist framework. In the last section, I deal with special forms of disagreement that have loomed large in recent discussions of Relativism. (shrink)

The most important argument against the B-theory of time is the paraphrase argument. The major defense against that argument is the “new” tenseless theory of time, which is built on what I will call the “indexical reply” to the paraphrase argument. The move from the “old” tenseless theory of time to the new is most centrally a change of viewpoint about the nature and determiners of ontological commitment. Ironically, though, the new tenseless theorists have generally not paid enough sustained, direct (...) attention to that notion. I will defend a general criterion of ontological commitment and apply it to generate a version of the new tenseless theory of time. I will argue that many of the extant versions of the new tenseless theory of time (specifically, all those which seek to identify tenseless truth-conditions of tensed sentences as a way out of apparent ontological commitment to tensed features of reality) are unsatisfactory because their general criterion of ontological commitment is inadequate. Those versions of the new tenseless theory which are adequate (specifically, those which identify tenseless truthmakers for tensed sentences) actually entail the criterion of ontological commitment that I defend, despite appearances to the contrary.

In this thesis, I examine the metaphysical debate between the A-theory and the B-theory of time, first by elaborating upon its proper characterization, and then by examining the sorts of evidence that are often thought to be germane to it. This debate, as I see it, is about whether or not time passes in any objective sense: the A-theory holds that it does, while the B-theory holds that it does not. I identify two opposing conceptions of time—that of the “time (...) of ordinary experience” on one hand, and that of “scientific time” on the other—and argue that the tension between them is the driving force behind this debate. I then examine two aspects of “evidence” from the time of ordinary experience: the phenomenological experience of time and the linguistic experience of time. It is often supposed, by both A- and B-theorists alike, that these sorts of evidence lend credence to the A-theory of time, since ordinary experience suggests that time passes. I hope to discredit this presumption, and so challenge the very framework in which this debate is so often carried out. In particular, by closely examining both of these kinds of experience—phenomenological and linguistic—in turn, I hope to provide a partial argument to the effect that the ordinary experience of time as a whole does not favour the A-theory over the B-theory of time. In the case of the phenomenological evidence, this is because the A-theory is just as inconsistent with such evidence as is the B-theory of time; in the case of the linguistic evidence, this is because the B-theory is equally consistent with such evidence as is the A-theory of time, particularly once it is revealed that a certain key assumption is tacitly accepted by both sides of the debate. Because of the popularity of the claim that the ordinary experience of time favours the A-theory, I take this conclusion to be something of a modest defence for the B-theory of time. (shrink)

David Sosa, Michael Nelson, and Jason Stanley have recently offered a series of interesting and provocative challenges to Kripke's modal arguments against Descriptivism. In this paper I explore these challenges and some of the issues to which they give rise. I argue that, in the end, all three challenges fail.

When discussing the distinction between referential and attributive uses of definite descriptions, Keith Donnellan also mentions cases such as ‘Smith’s murderer is insane’, uttered in a scenario in which Smith committed suicide. In this essay, I defend a two-fold thesis: (i) the alleged intuition that utterances of ‘Smith’s murderer is insane’ are true in the scenario in question is independent from the phenomenon of referential uses of definite description, and, most importantly, (ii) even if such intuition is granted semantic relevance, (...) the evidence it presents is compatible with a Russellian treatment of definite descriptions. I thus present a Russellian analysis of ‘Smith’s murderer is insane’ which, when coupled with certain independently plausible hypotheses, explains the presumed intuition that certain utterances of this sentence are indeed true, at least as long as the intended individual is insane.

The extensions of vague predicates like ‘is bald’, ‘is tall’, and ‘is a heap’ apparently lack sharp boundaries, and this makes such predicates susceptible to soritical reasoning, i.e. reasoning that leads to some version of the notorious sorites paradox. This essay is concerned with a certain kind of theory of vagueness, according to which the symptoms and puzzles of vagueness should be accounted for in terms of a particular species of context sensitivity exhibited by vague expressions. The basic idea is (...) that the extensions of vague predicates vary with certain contextual factors, and that this fact can explain why they appear to lack sharp boundaries. This kind of view is referred to as contextualism about vagueness. A detailed characterisation of contextualism about vagueness is given in chapter two and three. In chapter two, a generic version of contextualism about vagueness is developed, and some alternative forms of context sensitivity are introduced. In chapter three, the specific contextual factors appealed to by different contextualists are discussed. In chapter four, different contextualist diagnoses of the sorites paradox are considered, and found to be problematic in various ways. It is argued that contrary to what some of its proponents have claimed, contextualism about vagueness is not superior to other comparable theories of vagueness when it comes to explaining the appeal of soritical reasoning. In chapter five, a certain version of the sorites paradox, known as the forced march sorites, is discussed. It is argued that “data” about how speakers would behave in the forced march cannot lend any firm support to contextualism about vagueness. In chapter six, some problems concerning the instability of the contextual factors are considered. One problem is that contextualist diagnoses of the sorites which locate a fallacy of equivocation in the reasoning seem to render non-soritical reasoning fallacious as well. A model for treating this problem is suggested, but on closer consideration, it turns out to be problematic. Moreover, this model is of no help in solving the more general problem that even if classical logic remains valid for vague language on some contextualist views, the instability of the extensions of vague predicates makes it difficult to know when a certain piece of reasoning instantiates a valid argument form. Other difficulties arise with respect to speech reports and belief contents. Chapter seven concludes with a summary and some methodological remarks. (shrink)

According to a widespread picture due to Kaplan, there are two levels of semantic value: character and content. Character is determined by the grammar, and it determines content with respect to context. In this chapter Recanati criticizes that picture on several grounds. He shows that we need more than two levels, and rejects the determination thesis: that linguistic meaning as determined by grammar determines content. Grammatical meaning does not determine assertoric content, he argues, but merely constrains it — speaker’s meaning (...) necessarily comes into play. On the alternative picture he offers, there are four basic levels, only one of which is determined by the grammar. Pragmatics is what enables the transition from each level to the next. (shrink)

This paper argues that relativity of truth to a world plays no significant role in empirical semantic theory, even as it is done in the model-theoretic tradition relying on intensional type theory. Some philosophical views of content provide an important notion of truth at a world, but they do not constrain the empirical domain of semantic theory in a way that makes this notion empirically significant. As an application of this conclusion, this paper shows that a potential motivation for relativism (...) based on the relativity of truth to a world fails. (shrink)

Aristotle and Aquinas may have held that the things we believe and assert can have different truth-values at different times. Stoic logicians did; they held that there were “vacillating assertibles”—assertibles that are sometimes true and sometimes false. Frege and Russell endorsed the now widely accepted alternative, where the propositions believed and asserted are always specific with respect to time. This paper brings a new perspective to this question. We want to figure out what sorts of propositions speakers believe. Some philosophers (...) have argued that we must take agents to believe temporalist propositions—propositions that are inspecific with respect to time—if we’re to explain the agent’s own thoughts and inferences. I’ll explore another strategy. I’ll focus on our ability to think and reason about the beliefs that other people have. I’ll suggest that an adequate account of that ability requires that we take others to believe some temporalist propositions. I also ask whether all propositions can be specific with respect to worlds, and close by exploring some general issues. (shrink)

According to David Lewis, many de re modal predications – that is, sentences such as ‘John McCain could have won the 2008 U.S. Presidential election’ and ‘Dwight could receive a promotion’ – are inconstant insofar as their truth values can vary alongside changes in our interests. In this paper, I argue that previous accounts of this inconstancy, such as those offered by Lewis and Harold Noonan, are inadequate. Linguistic data, I claim – specifically, agreement and disagreement data – tell against (...) these views and in favor of a new, more radical approach. My goal in this paper is to present such data in an effort to offer some initial motivation for this new approach. (shrink)

In this dissertation, I investigate a conception of thoughts figuring in ordinary discourse, and argue that this conception is an improvement over a certain standard conception employed in current philosophical and linguistic endeavors. ;In Chapter 2, I discuss the leading principles of the standard conception, a conception according to which thoughts in general are to be identified with propositions. I also briefly preview some of the main features that distinguish the conception developed in the course of this study from the (...) standard conception. ;Chapter 4 is the heart of the thesis. I isolate a reading of the verb 'think' that I contend is both familiar from and central to our ordinary discourse about thoughts and thinking--the "generic reading", I call it. An investigation of the relation expressed by the verb, 'think', on this generic reading, and of the correlative conception of thoughts, occupies the remainder of the study. ;If this ordinary conception of thoughts is to serve the principal functions to which thoughts have standardly been assigned, in philosophical and linguistic endeavors, then there should be a discernible sense in which it is correct to say that thoughts, so conceived, are things that sentences express. In Chapter 5, I discuss the relevant notion of sentential expression. Accounts of this notion have commonly faced a stumbling block in the case of non-declarative sentences. What sort of thoughts, for example, can imperatives or interrogatives be said to express? In Chapter 6, I explain how, on the present conception, there is a clear sense in which sentences of a variety of grammatical moods--imperatives and interrogatives as well as declaratives--may be said, with equal propriety, to express thoughts. ;In Chapter 7, I discuss a fundamental thesis of the standard conception, and argue, in Chapter 8, that any account of the nature of thoughts accommodating this thesis is incompatible with the conception of thoughts arrived at in Chapter 4. Then, in order to retain this familiar conception and its benefits, a new account of the nature of thoughts must be provided. Such an account is described in Chapter 9. (shrink)

This paper distinguishes two importantly different kinds of temporalism. According to one version, the truth value of propositions is parameterized to times. According to a second version, propositions have a truth value simpliciter, but some propositions that are true will be or were false. I point out that the second version is neglected in Berit Brogaard's Transient Truths, and explore whether there are good arguments against it implicit in that work. I also critically engage with various arguments presented by Brogaard (...) against semantic eternalism. (shrink)
