Temporal externalism (TE) is the thesis (defended by Jackman (1999)) that the contents of some of an individual’s thoughts and utterances at time t may be determined by linguistic developments subsequent to t. TE has received little discussion so far, Brown 2000 and Stoneham 2002 being exceptions. I defend TE by arguing that it solves several related problems concerning the extension of natural kind terms in scientifically ignorant communities. Gary Ebbs (2000) argues that no theory can reconcile our ordinary, practical (...) judgments of sameness of extension over time with the claim that linguistic usage determines word extensions. I argue that Ebbs shows at most that no theory other than TE can effect this reconciliation. Furthermore, while Ebbs’ argument undermines Jessica Brown’s solutions to two closely related problems about natural kind term extensions (Brown 1998), TE can solve both problems without difficulty. Some criticisms of TE are briefly addressed as well. (shrink)

In this chapter I outline some metaphysical views about time, and about persistence, and discuss how they can help us clarify our thinking about life and death.

Abstract Temporal Externalism is the view that future events can contribute to determining the present content of our thoughts and utterances. Two objections to Temporal Externalism are discussed and rejected. The first is that Temporal Externalism has implausible consequences for the epistemology of biology and other taxonomic sciences (Brown, 2000). The second is that it is committed to implausible claims about dispositions.

What words we use, and what meanings they have, is important. We shouldn't use slurs; we should use 'rape' to include spousal rape (for centuries we didn’t); we should have a word which picks out the sexual harassment suffered by people in the workplace and elsewhere (for centuries we didn’t). Sometimes we need to change the word-meaning pairs in circulation, either by getting rid of the pair completely (slurs), changing the meaning (as we did with 'rape'), or adding brand new (...) word-meaning pairs (as with 'sexual harassment'). A problem, though, is how to do this. One might worry that any attempt to change language in this way will lead to widespread miscommunication and confusion. I argue that this is indeed so, but that's a feature, not a bug of attempting to change word-meaning pairs. The miscommunications and confusion such changes cause can lead us, via a process I call transformative communicative disruption, to reflect on our language and its use, and this can be further, rather than hinder, our goal of improving language.

A growing number of philosophers and linguists have argued that many, if not most, terms in our language should be understood as semantically context sensitive. In opposition to this trend, Herman Cappelen and Ernie Lepore defend a view they call "Semantic Minimalism", which holds that there are virtually no semantically context sensitive expressions in English once you get past the standard list of indexicals and demonstratives such as "I", "you", "this", and "that". While minimalism strikes many as obviously false, it (...) will be argued here that the view is more plausible than commonly assumed if one accepts the 'normative' conception of the relation between meaning and use characteristic of the literature on semantic externalism. That said, it is not clear that Cappelen and Lepore always conceive of their minimal semantic contents in this more normative fashion, and once this framework is place, a version of 'moderate contextualism' that they do not consider comes into view.

Assume consequentialism and assume moral properties are causally efficacious. Then, I’ll argue, a puzzle arises. These assumptions lead to denying each of two plausible metaphysical principles: that a cause cannot cause anything occurring before its ground and that a cause cannot cause anything belonging to its ground. We therefore have to reject either consequentialism or the causal efficacy of moral properties or the plausible metaphysical principles. And, I’ll show, the puzzle arises again even if we replace moral properties with the (...) non-moral properties making things right. Which component to reject is a question for another occasion: my aim here is to present the puzzle. It is a puzzle worth thinking about: no matter how we solve it, we stand to learn something, be it in normative ethics, metaethics, or metaphysics. And, I’ll suggest at the end of the paper, my arguments can be applied to other domains as well. (shrink)

Recent work on the problem of truth in serial fiction has focused on the semantics of certain sentences used to talk about serial fictions, as in Ross Cameron’s (2012) “How to Be a Nominalist and a Fictional Realist” and Andrew McGonigal’s (2013) “Truth, Relativism, and Serial Fiction,” or semantic properties of works themselves, as in Ben Caplan’s (2014) “Serial Fiction, Continued.” Here I argue that these proposed solutions are mistaken, and, more importantly, that the general approach to the problem is (...) mistaken: the problem of truth in serial fiction is an instance of the problem of change. Fictions can undergo change, much like you and me in certain respects. As a result, what is true in or according to them changes as well. (shrink)

I argue that the semantic content of thoughts and the linguistic meaning of expressions are things with a history in the sense that they can be made fully intelligible only from the point of view of the future. I defend this position by articulating a version of a view known in the philosophy of language as temporal externalism. Temporal externalism about content is the view that the content of a subject’s thoughts and utterances at a time t depends on features (...) of the linguistic practices of her community after t. There are two different ways in which temporal externalism can be developed. First, one can take it to be the view according to which the meaning of an expression is given by the whole pattern of use, including future ones, of that expression. Alternatively, one can interpret temporal externalism as the view that the meaning of a speaker’s utterance is determined by the norms that govern or constrain her linguistic behaviour. These norms, which may be instituted at a later date, place their authoritative stamp upon prior conduct. I show that the first version of temporal externalism faces severe objections from which the second version is immune. I also provide a defence of this second position through an extensive discussion of some thought experiments. (shrink)

Locke's claims about the "inadequacy" of substance-ideas can only be understood once it is recognized that the "sort" represented by such an idea is not wholly determined by the idea's descriptive content. The key to his compromise between classificatory conventionalism and essentialism is his injunction to "perfect" the abstract ideas that serve as "nominal essences." This injunction promotes the pursuit of collections of perceptible qualities that approach ever closer to singling out things that possess some shared explanatory-level constitution. It is (...) in view of this norm regulating natural-historical inquiry that a substance-idea represents a sort for which some such constitution serves as the "real essence," i.e. as that on which all the sort's characteristic "properties" depend. (shrink)

Huw Price holds that a recognizable version of expressivism about normative and modal language can be “globalized” so as to apply to all areas of discourse. He focuses on globalizing the anti-representationalism of expressivist theories. By contrast, this paper’s topic is the seldom-discussed way Price seeks to globalize the expressivist view that “non-descriptive” discourse exhibits subjectivity. I argue that Price’s own argument against the possibility of a purely objective domain conflicts with his anti-representationalism and is self-undermining. I then defend a (...) different strategy for arguing that a kind of subjectivity can emerge even in domains traditional expressivists have regarded as purely objective. I do so by using an account of assertoric practice to offer a new solution to a puzzle concerning how to describe contingent histories in the use of natural kind terms. (shrink)

Temporal externalists expand Putnam’s and Burge’s semantic externalisms to argue that later uses of words transform the semantic significance of earlier uses. Conflicting intuitions about temporal externalism often turn on different conceptions of linguistic practice, which have mostly not been thematically explicated. I defend a version of temporal externalism that replaces the familiar regularist and normative-regulist conceptions of linguistic practice or use. This alternative identifies practices neither by regularities of use, nor by determinate norms governing their constituent performances, but by (...) the ways those performances bear upon and are accountable to one another. Performances are intelligible as part of a larger pattern of practice, but different performances extend that pattern in partially conflicting ways. The essentially anaphoric concepts of “issues” and “stakes” allow us to talk about how alternative extensions of past performance conflict or otherwise mis-align , and what differences it would make to extend the practice in one way rather than another . The result is to recognize both the interdependence of linguistic performances, and the open texture of concepts, by situating them within broader patterns of discursive interaction with changing circumstances.

Most linguists and philosophers will tell you that whatever meaning is, it determines the reference of names, the satisfaction conditions of nouns and verbs, the truth conditions of sentences; in linguist speak, meaning determines semantic value. So a change in semantic value implies a change in meaning. So the semantic value a meaning determines is essential to that meaning: holding contributions from context constant, if two words have different semantic values they cannot mean the same thing. If this is correct, (...) then in a fairly straightforward sense reference is essential to meaning. In this paper I argue that reference is not essential to meaning by giving an example in which groups in different circumstances use a phrase with the same meaning but a different reference.

Many trans women (men) say that they know that they are women (men). Anti-trans activists deny the claims trans people say they know. Many say that social kinds like woman, Latinx, and consent are in some important sense constructed in the social world and are thus open to a certain amount of engineering. I think the claims to knowledge trans people make are correct, and I think it correct that such things as gender, race, and consent are constructed by society (...) and so are prime candidates for what philosophers these days call conceptual engineering. But it is not all that easy to see how the claim about knowledge and the claim that what is known is determined by the vagaries of the social world are to be reconciled. In this paper I argue that this is a real problem, that it has a solution, and that the solution tells us something important about what happens when we contest norms or engineer concepts. (shrink)

The linguistic meaning of a word in a language is what fully competent speakers of the language have a grasp of merely in virtue of their semantic competence. The meanings of words sometimes change over time. 'Meat' used to mean 'solid food', but now means 'animal flesh eaten as food'. This type of meaning change comes with change of topic, what we’re talking about. Many people interested in conceptual engineering have claimed that there is also meaning change where topic is (...) retained. For example, they claim that the meanings of ‘fish’ and ‘pasta’ have undergone such change and that the meaning of 'marriage' would change this way after gay marriages become legal and widely accepted. In this paper I relate two sets of relatively independent literatures: mainstream philosophy of language and conceptual engineering to argue that on a plausible and widely accepted Minimalist view of meaning that is part and parcel of anti-descriptivism none of the above sorts of cases involve meaning change with topic retention. I do this by showing how to distinguish minimalism about meaning from the related theses of externalism and anti-individualism about intension and how to separate meaning from intension in a way that allows meaning and topic to remain the same despite changes in intension. The larger lesson is that much like we shouldn’t disregard the boundary between the narrowly meaning-related (“semantics”) and the more broadly communication-related (“pragmatics”), we shouldn’t disregard the boundary between the former and the more broadly thought-related, conceptual or cognitive (“cognition”).

In a trio of recent articles, Johnson and Nado defend a form of metasemantic dispositionalism, arguing for a novel approach to the “error”-problem, based on speakers’ dispositional states under what they call a state of “full information”. In this article, I argue that their brand of dispositionalism fails to solve the “error”-problem, because of what I think of as counterexamples to it. In the final sections, I propose a way to amend the theory to shield it from some of the (...) counterexamples, based on the idea that what determines meaning is not only dispositions to apply words under full information, but also dispositions to evaluate one’s prior usage, under full information.

Evans (1973)’s Madagascar case and other cases like it have long been taken to represent a serious challenge for the Causal Theory of Names. The present essay answers this challenge on behalf of the causal theorist. The key is to treat acts of uttering names as events. Like other events, utterances of names sometimes turn out to have features which only become clear in retrospect.

In his 1975 paper “The Meaning of ‘Meaning’”, Hilary Putnam famously argued for semantic externalism. Little attention has been paid, however, to the fact that already in 1973, Putnam had presented the idea of the linguistic division of labor and the Twin Earth thought experiment in his comment on Wilfrid Sellars’s “Meaning as Functional Classification” at a conference, and Sellars had replied to Putnam from a broadly inferentialist perspective. The first half of this paper aims to trace the development of (...) Putnam’s semantic externalism, situate his debate with Sellars in it, and reconstruct the two arguments he presented against Sellars. The second half of this paper aims to reconstruct how Sellars replied to Putnam. I argue that Sellars not only accepts the social character of language but also suggests how inferentialists can accommodate the contribution of the world. Sellars’s key idea is that substance terms have a “promissory note aspect” which is to be cashed out in a successor conceptual framework. I reconstruct Sellars’s position as ideal successor externalism, and compare it with temporal externalism. (shrink)

Patrick Todd argues for a modified Peircean view on which all future contingents are false. According to Todd, this is the only view that makes sense if we fully embrace an open future, rejecting the idea of actual future history. I argue that supervaluational accounts, on which future contingents are neither true nor false, are fully consistent with the metaphysics of an open future. I suggest that it is Todd's failure to distinguish semantic and postsemantic levels that leads him to (...) suppose otherwise. I also show how one can resist Todd's argument (with Brian Rabern) that the conceptual possibility of omniscience requires us to reject Retro‐closure (). (shrink)

In previous work we proposed a sketch of a disposition-based metasemantictheory, which has recently been criticized by James Andow. Andow claims, first, that our dispositionalmetasemantics threatens to render the meanings of our words indeterminate, and second, that our viewrisks a 'semantic apocalypse' according to which most of our terms fail to refer. We respond to Andow'scriticism by modifying and expanding our orignial, underspecified view. In particular, we propose that a viewthat appeals to actual dispositions rather than counterfactual dispositions avoids many (...) difficulties that might confront a disposition-based metasemantics - issues even beyond those that Andow raises.

'Epistemic' theories of vagueness notoriously claim that (despite the appearances to the contrary) all of our vague terms have sharp boundaries, it's just that we can't know what they are. Epistemic theories are typically criticized for failing to explain (1) the source of the ignorance postulated, and (2) how our terms could come to have such precise boundaries. Both of these objections will, however, be shown to rest on certain 'presentist' assumptions about the relation between use and meaning, and if (...) allows that the meaning constitutive elements of our linguistic practices can extend into the future, the possibility of a new sort of 'normative epistemicism' emerges. (shrink)

ABSTRACT Our ascriptions of content to past utterances assign to them a level of conceptual continuity and determinacy that extends beyond what could be grounded in the usage up to their time of utterance. If one accepts such ascriptions, one can argue either that future use must be added to the grounding base, or that such cases show that meaning is not, ultimately, grounded in use. The following will defend the first option as the more promising of the two, though (...) this ultimately requires understanding the relation between use and meaning as ‘normative’ in two important ways. The first way is that the function from use to meaning must be of a sort that allows us to maintain a robust distinction between actual and correct use. The second sort of normativity is unique to theories that extend the grounding base into the future. In particular, if meaning is partially a function of future use, we can see our commitment to the ‘determinacy’ of meaning as a practical commitment that structures our linguistic practices rather than a theoretical commitment that merely describes them. (shrink)

Temporal externalists argue that ascriptions of thought and utterance content can legitimately reflect contingent conceptual developments that are only settled after the time of utterance. While the view has been criticized for failing to accord with our “ordinary linguistic practices”, such criticisms (1) conflate our ordinary ascriptional practices with our more general beliefs about meaning, and (2) fail to distinguish epistemically from pragmatically motivated linguistic changes. Temporal externalism relates only to the former sort of changes, and the future usage relevant (...) to what we mean reflects reason-driven practices that are rational for us to defer to. (shrink)

While philosophers of language have traditionally relied upon their intuitions about cases when developing theories of reference, this methodology has recently been attacked on the grounds that intuitions about reference, far from being universal, show significant cultural variation, thus undermining their relevance for semantic theory. I’ll attempt to demonstrate that (1) such criticisms do not, in fact, undermine the traditional philosophical methodology, and (2) our underlying intuitions about the nature of reference may be more universal than the authors suppose.

Semantic holists view what one's terms mean as function of all of one's usage. Holists will thus be coherentists about semantic justification: showing that one's usage of a term is semantically justified involves showing how it coheres with the rest of one's usage. Semantic atomists, by contrast, understand semantic justification in a foundationalist fashion. Saul Kripke has, on Wittgenstein's behalf, famously argued for a type of skepticism about meaning and semantic justification. However, Kripke's argument has bite only if one understands (...) semantic justification in foundationalist terms. Consequently, Kripke's arguments lead not to a type of skepticism about meaning, but rather to the conclusion that one should be a coherentist about semantic justification, and thus a holist about semantic facts.

Most meanings we express belong to large families of variant meanings, among which it would be implausible to suppose that some are much more apt for being expressed than others. This abundance of candidate meanings creates pressure to think that the proposition attributing any particular meaning to an expression is modally plastic: its truth depends very sensitively on the exact microphysical state of the world. However, such plasticity seems to threaten ordinary counterfactuals whose consequents contain speech reports, since it is (...) hard to see how we could reasonably be confident in a counterfactual whose consequent can be true only if a certain very finely tuned microphysical configuration obtains. This essay develops the foregoing puzzle and explores several possible solutions. (shrink)

This article presents a defense of “presentist externalism,” that is, the claim that memory contents are fixed by the environment and by the time at which a recollection takes place rather than by those at which the original mental state occurred. Its case is an instance of an argument to the best explanation. The author argues, firstly, that “presentist externalism” is the only version of content externalism that can stand up to both Boghossian’s memory and fallacy arguments. In slow switching (...) cases, inferences containing memory thoughts as premises are unsound or unsafe, but valid. The author contends, secondly, that the externalist must recognize the existence of wide mismemories besides wide forgetting and that only the presentist externalist can account for their existence. The author maintains, finally, that if the validity of an inference requires that all its premises and conclusion be evaluated in the same context, that in which the inference is made, then it is the present context that fixes the content and the concepts of memory rather than the past.

Content externalism about memory says that the individuation of memory contents depends on relations the subject bears to his past environment. I defend externalism about memory by arguing that neither philosophical nor psychological considerations stand in the way of accepting the context dependency of memory that follows from externalism.

ABSTRACT Contemporary relativists often see their view as contributing to a semantic/post-semantic account of linguistic data about disagreement and retraction. I offer an independently motivated metasemantic account of the same data, that also handles a number of cases and empirical results that are problematic for the relativist. The key idea is that the content of assertions and beliefs is determined in part by facts about other times, including times after the assertion is made or the belief is formed. On this (...) temporal externalist view, speaker behaviours such as retraction of previous assertions play a role in making it the case that a past utterance has a given meaning. (shrink)

The idea that experts (especially scientific experts) play a privileged role in determining the meanings of our words and the contents of our concepts has become commonplace since the work of Hilary Putnam, Tyler Burge, and others in the 1970s. But if experts have the power to determine what our words mean, they can do so responsibly or irresponsibly, from good motivations or bad, justly or unjustly, with good or bad effects. This paper distinguishes three families of metasemantic views based (...) on their attitudes towards bad behaviour by meaning-fixing experts, and draws a series of distinctions relevant for the normative evaluation of meaning-determining actions.

The purpose of this paper is to present and discuss a puzzle involving accommodation. The puzzle is based on three assumptions. The first assumption is that accommodation takes place after an utterance. The second assumption is that accommodation can make a difference to the truth-value of an utterance even if the utterance is not about the future. The third assumption is that something that takes place after an utterance cannot make a difference to the truth-value of the utterance unless the (...) utterance is about the future. Since these assumptions are jointly inconsistent, one of them must be false. The question is which one we ought to reject. The majority of the discussion is devoted to discussing each of the options, and the tentative conclusion is that the most plausible strategy is to reject the third thesis. That amounts to saying that something that takes place after an utterance can make a difference to the truth-value of the utterance even if the utterance is not about the future. (shrink)

Complete information dispositional metasemantics says that our expressions get their meaning in virtue of what our dispositions to apply those terms would be given complete information. The view has recently been advanced and argued to have a number of attractive features. I argue that that it threatens to make the meanings of our words indeterminate and doesn’t do what it was that made a dispositional view attractive in the first place.

This paper raises a new form of speaker error objection to the analysis of disputes as metalinguistic negotiations in cases in which disputants reject that analysis. It focuses on an obvious but underexplored form of speaker error: speakers’ misattribution of contents both to others and to themselves. It argues that the analyses of disputes that posit this type of speaker error are uncharitable in three different ways: first, by portraying speakers as mistaken interpreters of their interlocutors; second, by portraying speakers (...) as uncharitable interpreters of their interlocutors; third, by portraying speakers who retract their claims as mistaken interpreters of their own prior utterances. Taken together, these unfavorable consequences weigh significantly against the plausibility of this type of analysis for the cases in question. (shrink)

Temporal externalism posits that the meanings of words inherently incorporate properties closely tied to future usage and aims to develop models for the evolution of word meanings within normative-like frameworks. However, these models face significant challenges due to an unwavering focus on how specific words change across diverse practices. A more suitable strategy entails examining the relationship between specific practices and different words, allowing us to naturally replace shifts in agent beliefs for changes in word meanings over time, which may (...) lead to certain contradictions if they insist on asserting changes in word meanings from an external perspective.

This thesis develops methods for representing how the contents of theories of meaning become conceived by their users. These contents are treated as the range of systematically elicited conceptions afforded by a designated corpus of key texts. The approach being taken involves first detailing a formal scheme for the components of situations attributed to various entities. This scheme is then applied as a framing device to form a template which accounts for the shared structure between the mental spaces which embody (...) how people conceive different theories of meaning. For the purposes of this task, cognition is treated as embodied in the sense that both the form and content of personal conceptualisations are largely dependent on what both bodily and ecological factors afford. The purpose of this approach is to help understand how theories operate when viewed as worldly entities within a materialist framework. The significance of such understanding lies in enabling analyses and comparisons which account for the effects of material restrictions such as how a theory’s presentation must necessarily be selective and how human cognition operates on models set by precedent. The framework being provided here allows the conceptions each individual theory of meaning elicits to be reduced to formal, commensurate models which account for differences between typical influences on the conceptions characteristic of different demographics such as experts of related fields. Approaching theories of meaning from this angle also reveals new avenues of comparison concerning otherwise implicit details. One involves theory-internal conditions on the full material identity of meaning-instantiating entities. The other concerns the extent of the domains for aggregating applicable influences for which a theory accounts and the range of those it may accommodate. (shrink)

Este texto tem como objetivo apresentar a principal motivação filosófica para se defender uma teoria causal da memória, que é explicar como pode um evento que se deu no passado estar relacionado a uma experiência mnêmica que se dá no presente. Para tanto, iniciaremos apresentando a noção de memória de maneira informal e geral, para depois apresentar elementos mais detalhados. Finalizamos apresentando uma teoria causal da memória que se beneficia da noção de veritação (truthmaking).

Our ascriptions of content to utterances in the past attribute to them a level of determinacy that extends beyond what could supervene upon the usage up to the time of those utterances. If one accepts the truth of such ascriptions, one can either (1) argue that subsequent use must be added to the supervenience base that determines the meaning of a term at a time, or (2) argue that such cases show that meaning does not supervene upon use at all. (...) The following will argue against authors such as Lance, Hawthorn and Ebbs that first of these options is the more promising of the two. However, maintaining the supervenience thesis ultimately requires understanding the relation between use and meaning as 'normative' in two important ways. The first (more familiar) way is that the function from use to meaning must be of a sort that allows us to maintain a robust distinction between correct usage and actual usage. This first type of normativity is accepted by defenders of many more temporally restricted versions of the supervenience thesis, but the second sort of normativity is unique to theories that extend the supervenience base into the future. In particular, if meaning is partially a function of future use, we can understand other commitments we are often taken to have about meaning, particularly the commitment to meaning being 'determinate', as practical commitments that structure our linguistic practices rather than theoretical commitment that merely describe such practices.

Another paper exploring the relation between Temporal externalism and Epistemicism about Vagueness, but with slightly more emphasis on the role of constitutive norms relating to our concept of truth.

NB: This paper has been largely displaced by my: “Externalism, Metasemantic Contextualism and Self-Knowledge”, in Goldberg, (ed.) Externalism, Self-Knowledge and Skepticism. New York: Oxford University Press, 2015, pp. 228-247. // -/- While straightforwardly ambiguous words like “bank” and obviously indexical words like “I” are unproblematically treated as referring to different things in different contexts, such variations are displayed by terms that seem neither ambiguous nor indexical. This paper will argue that traditional accounts of word meaning (in which a single fixed (...) meaning is attached to each entry in one’s ‘mental lexicon’) have problems accounting for how the referent of a non-ambiguous/non-indexical term can shift from context to context, while a moderate version of semantic holism can do so by understanding the comparative weight of the meaning-constitutive beliefs as itself something which can vary from context to context.

According to retail realism, we ought to abandon wholesale arguments, which purport to demonstrate realism or anti-realism about theoretical entities in general, and embrace retail arguments, which purport to demonstrate realism or anti-realism about specific kinds of theoretical entities. My aim is to argue that there is a further wholesale element that retail realism must avoid in order to qualify as a viable position. In order to do so, I distinguish between what I call wholesale and retail treatments of theoretical (...) entities. Wholesale treatments individuate theoretical entities in such a way that the same entity can appear in distinct theories. In that case, realism about a given entity implies realism about that entity as it appears in a number of distinct theories. Retail treatments, on the other hand, individuate theoretical entities more finely, so that distinct theories actually involve distinct entities. In that case, realism about one entity needn't imply realism about a similar, but distinct, entity. I argue that retail realists ought to reject wholesale treatments in favor of retail treatments, and I do so by examining a case from the history of chemistry involving the hypothetical constituent of hydrochloric acid known as the muriatic radical. I argue that there are distinct muriatic radicals in distinct theories, and that we ought to be realists about some, but not others. Hence, in this case, a retail treatment is preferable to a wholesale one, and I conclude by discussing why the combination of retail realism and retail treatments constitutes an attractive position within the scientific realism debate more generally.
