So-called Neo-Russellians, such as Salmon, Braun, Crimmins, and Perry, hold that the semantic content of ‘ n is F ’ in a context c is the singular proposition ⟨ o, P ⟩, where o is the referent of the name n in c, and P is the property expressed by the predicate F in c. This is also known as the Neo-Russellian theory. Using truth ascriptions with names designating propositions, such as ‘Goldbach's conjecture’, in this paper, I will argue that, (...) together with highly plausible principles regarding a priori knowledge, the Neo-Russellian theory leads to unacceptable consequences. I will call this ‘the Goldbach puzzle’. Since the solution to the Goldbach puzzle cannot be to reject the discussed principles regarding a priori knowledge, the puzzle will undermine the Neo-Russellian theory. (shrink)

Zeugmatic oddness is a linguistic intuition of oddness with respect to an instance of zeugma, i.e. a sentence containing an instance of a homonymous or polysemous word being used in different meanings or senses simultaneously. Zeugmatic oddness is important for philosophical debates as philosophers often use it to argue that a particular philosophically interesting expression is ambiguous and that the phenomenon referred to by the expression is disunified. This paper takes a closer look at zeugmatic oddness. Focusing on relevant psycholinguistic (...) literature on homonymy and polysemy processing and representation, I argue that there are two different ways in which zeugmatic oddness can arise. Philosophical upshots concerning zeugmatic oddness are then drawn. (shrink)

A family of familiar linguistic tests purport to help identify when a term is ambiguous. These tests are philosophically important: a familiar philosophical strategy is to claim that some phenomenon is disunified and its accompanying term is ambiguous. The tests have been used to evaluate disunification proposals about causation, pain, and knowledge, among others. -/- These ambiguity tests, however, have come under fire. It has been alleged that the tests fail for polysemy, a common type of ambiguity, and one that (...) is at issue in philosophically interesting cases. Furthermore, the objection that the tests fail for polysemy is often taken to be an undeniable bit of linguistic data. -/- We argue that this is mistaken. The objection implicitly relies on controversial assumptions about how to account for copredicational sentences, in which a single argument is ascribed prima facie incompatible properties. Furthermore, on several viable theories of copredication, the objection fails. However, our discussion also reveals that even if ambiguity tests are preserved, they may be significantly harder to execute than previously thought. (shrink)

Formal epistemologists often claim that our credences should be representable by a probability function. Complete probabilistic coherence, however, is only possible for ideal agents, raising the question of how this requirement relates to our everyday judgments concerning rationality. One possible answer is that being rational is a contextual matter, that the standards for rationality change along with the situation. Just like who counts as tall changes depending on whether we are considering toddlers or basketball players, perhaps what counts as rational (...) shifts according to whether we are considering ideal agents or creatures more like ourselves. Even though a number of formal epistemologists have endorsed this type of solution, I will argue that there is no way to spell out this contextual account that can make sense of our everyday judgments about rationality. Those who defend probabilistic coherence requirements will need an alternative account of the relationship between real and ideal rationality. (shrink)

A number of authors have defended permissivism by appealing to rational supererogation, the thought that some doxastic states might be rationally permissible even though there are other, more rational beliefs available. If this is correct, then there are situations that allow for multiple rational doxastic responses, even if some of those responses are rationally suboptimal. In this paper, I will argue that this is the wrong approach to defending permissivism—there are no doxastic states that are rationally supererogatory. By the lights (...) of contemporary linguistics, ‘rational’ is an absolute gradable adjective, and as such, can only be applied to things that satisfy the top of the scale of rationality. For this reason, it is not possible to believe what is rational while also failing to believe what is rationally optimal. (shrink)

Provisional draft, pre-production copy of my book “The Modal Future” (forthcoming with Cambridge University Press).

Some words express different meanings in different contexts, such as “bank” and “I.” Linguistic alethic pluralists claim that “true” is another such word. This is a surprising thesis that holds implications for debates about the nature of truth. Yet it is in need of careful elaboration and evaluation. I describe several versions of linguistic alethic pluralism, alongside tests that natural language theorists use to identify different types of meaning variation. I also consider empirical studies that have recently targeted the use (...) of “true.” I conclude that there is currently no evidence for linguistic alethic pluralism, and unlikely to be any forthcoming.

ABSTRACT Against the maximizing conception of practical rationality, Michael Slote has argued that rationality does not always require choosing what is most rational. Instead, it can sometimes be rational to do something that is less-than-fully rational. In this paper, I will argue that maximizers have a ready response to Slote’s position. Roy Sorensen has argued that ‘rational’ is an absolute term, suggesting that it is not possible to be rational without being completely rational. Sorensen’s view is confirmed by the fact (...) that, by the lights of contemporary linguistics, ‘rational’ is an absolute gradable adjective. Because ‘rational’ is an absolute gradable adjective, being rational requires being at the top of the scale of rationality, making anyone who is not fully rational positively irrational. Contra Slote, the only way to be rational enough is to be maximally rational. (shrink)

Cross-linguistic comparisons serve as empirical tests generating evidence for and against lexical ambiguity in words like “good”, “know”, “the”, “can”, and “may”. Critics question such comparisons' validity. This article examines how cross-linguistic comparisons are treated as tests and shows that they have two predominant forms: one modeled on modus tollens, and another on Bayes' theorem, where the former is an enthymematic version of the latter. This analysis reveals the strengths and weaknesses of cross-linguistic comparisons, and thereby guides interpretation of their (...) results. It concludes that cross-linguistic comparisons generally yield stronger evidence against lexical ambiguity than for it. (shrink)

Copredication is the phenomenon whereby two or more predicates seem to require that their argument denotes different things. The denotation of words that copredicate has been broadly discussed. In this paper, I investigate the metaphysics behind this question. Thus, mereological theories of dot objects claim that these nouns denote complex entities; Asher (Lexical meaning in context, Cambridge University Press, 2011, https://doi.org/10.1017/CBO9780511793936) thinks that they denote bare particulars; and the Activation Package Theory contends that they stand for multiple denotations. According to (...) the Activation Package Theory, copredicative nouns stand for complex knowledge structures that offer a range of multiple potential denotations. In this paper, I claim that the Activation Package Theory contributes to solve some of the metaphysical questions that arise from copredication. (shrink)

Viebahn (2018) has recently argued that several tests for ambiguity, such as the conjunction-reduction test, are not reliable as tests for polysemy, but only as tests for homonymy. I look at the more fine-grained distinction between regular and irregular polysemy and I argue for a more nuanced conclusion: the tests under discussion provide systematic evidence for homonymy and irregular polysemy but need to be used with more care to test for regular polysemy. I put this conclusion at work in the (...) context of the debate over the alleged referential-attributive ambiguity of the definite article. In reply to various criticisms, defenders of the ambiguity view argue that this is a case of polysemy. But opponents object that the dual use of the definite article fails tests for ambiguity. The debate seems to have come to stalemate, unless the relevance of the tests is determined for cases of alleged polysemy. I conclude that the balance of considerations incline towards rejecting the ambiguity thesis. (shrink)

ABSTRACT This paper explores a taxonomy of uses of ‘because’ from the linguistics literature. It traces the apparent semantic differences between content, epistemic, and act ‘because’ to differences in attachment height. But it argues that the fact that these uses of ‘because’ never occur in the same environments is evidence of an underlying semantic unity. Arguments from such a distribution to underlying unity are familiar from phonology and morphology, and they are implicit in Quine's comments on ambiguity in Word and (...) Object, but they have too rarely been deployed in semantics. Here, such an argument points the way towards an underexplored conception of polysemy, while also making progress on the rather more limited topic of the lexical semantics of ‘because’. (shrink)

There is a widespread and largely unchallenged assumption within philosophy that the word ‘normal’ is ambiguous: i.e., that it can mean different things in different contexts. This assumption appears in work within topics as varied as the philosophy of biology, medicine, justification, causation, and more. In this paper I argue that we currently lack any independent reason for adopting such an assumption. The reason that would most likely be offered in its favour requires us to ignore an alternative and equally (...) plausible explanation for the seeming variety of different meanings that ‘normal’ is taken to have. Meanwhile, the well-known conjunction reduction test for ambiguity provides no evidence for the ambiguity of ‘normal’, and in fact suggests that maintaining this ambiguity claim is more difficult than has been initially supposed. Therefore, with the way things stand at present, it should not be assumed without argument that ‘normal’ is an ambiguous term. (shrink)

The thesis advanced in this paper is that the proper names of cities or countries inherit the linguistic types of the nouns which denote the basic category of the objects the names refer to. As a result, in the case of the proper names of cities or countries, a reference by those names may select particular aspects of those objects, in the same way that book or newspaper selects the physical or informational aspects of objects in the extension of the (...) nouns. This view is based on Asher’s and Pustejovsky’s conception of dot type semantics. (shrink)

According to a standard picture, normative reasons do not extend beyond the boundaries of agency. If something isn’t an agent, then there can’t be normative reasons for it to do one thing rather than another. This paper argues that the standard picture is false. There are reasons for smoke detectors to alarm when exposed to smoke, and for Venus Flytraps to close around their prey when stimulated. I argue that the collapse of the standard picture has important implications for philosophical (...) debates about reasons, and especially serious consequences for theories that analyse normative reasons in terms of the standards of good practical reasoning.

Zeugma (“The storm sank my boat and my dreams”) is a well-recognized figure of speech whose mechanism of operation is less well understood. We suggest treating zeugma as a breach of syntactic iconicity: the syntactic form of the coordinative construction statement implies an equivalence or semantic proximity between the two objects of the verb (boat and dreams), while the objects supplied are semantically very distant. Unlike nominal metaphors and similes, in zeugmas two metaphorically-related, nonsymmetrical objects are put in syntactically symmetrical (...) positions. This feature, the breach of iconicity, registers as a surprise, an effect wholly different from that of metaphors and similes. Seeing zeugma in these terms makes it possible not just to explain its functioning beyond broad pronouncements about yoking together different items, but to tease apart syntactic and semantic factors that contribute to the level of the breach of iconicity and subsequently to the zeugma’s strength. Moreover, understanding zeugmas as a surprising breach of iconicity leads to the question of how this breach may be accommodated or made sense of. In the second part of the essay, we introduce three types of accommodation strategies, each with a distinct focus: the language, the objects, and the speaker. (shrink)

Proper names are usually considered devices of singular reference but, when considered as word-types, they also exhibit other kinds of uses. In this paper I intend to show that systematic kinds of uses of proper names considered as word-types can be accounted for by a generalized rule-based conception of systematic polysemy, one which not only postulates a multiplicity of stable senses for an expression, but also a multiplicity of content generating rules, each of which determines potentially different contents in different (...) contexts. In contrast to the currently extant polysemous conceptions of proper names (Leckie in Philos Stud 165:1139–1160, 2013), which only encompass individual and predicative uses, the presented proposal concerns all systematic uses of proper names considered in the literature, i.e., individual, predicative, deferred, descriptive, anaphoric, and bound uses of proper names. The resulting conception accommodates referential intuition about the default individual uses of proper names while also admitting other kinds of uses without generating homonymy. It transpires that proper names are semantically underdetermined and context-sensitive expressions. (shrink)
