I argue that conventional implicatures embed in logical compounds, and are non-truth-conditional contributors to sentence meaning. This, I argue has significant implications for how we understand truth, truth-conditional content, and truth-bearers.

Gary Ebbs shows that this appearance is illusory.

There is a certain approach to the semantic paradoxes that is highly intuitive and for that reason alone never seems to go away. Roughly put, it's the idea that the paradoxical sentences just don't really have any truth conditions at all, no matter how grammatically sound and meaningful they and their parts are. I suppose that just about anyone who spends even a relatively modest amount of time thinking about the paradoxes comes up with this idea eventually. There is a (...) great deal to recommend this approach, especially when it carefully distinguishes sentence tokens from sentence types. For one thing, it requires no significant alteration in commonsensical views about language or logic. Let us call it the Token Approach, as it trades on distinguishing linguistic tokens from types. The approach does not contain any of the flashy logical moves that characterize most other current responses to the semantic paradoxes. Many contemporary philosophers of language and logic ignore the Token Approach in part because, it seems, they cannot display their logical chops when investigating it. Despite this devastating drawback, the approach strikes me as good as any. -/- It faces two obstacles: it apparently lacks a plausible explanation of how certain type-identical sentence tokens can differ in truth conditions, and it may fail to adequately deal with certain paradoxical sentences of the liar family. However, I don't take the obstacles to be insurmountable: in each case the advocate of the Token Approach can appeal to a traditional and highly credentialed-if controversial and obscure-contemporary view of linguistic meaning that promises to supply suitable ways around both obstacles.

In this essay (for undergraduates) I introduce three of the famous semantic paradoxes: the Liar, Grelling’s, and the No-No. Collectively, they seem to show that the notion of truth is highly paradoxical, perhaps even contradictory. They seem to show that the concept of truth is a bit akin to the concept of a married bachelor—it just makes no sense at all. But in order to really understand those paradoxes one needs to be very comfortable thinking about how lots of interesting (...) sentences talk about not dogs or cats or elections or baseball but sentences. That is, we need to get familiar analyzing sentences that talk about sentences. (shrink)

The semantic paradoxes, whose paradigm is the Liar, played a crucial role at a crucial juncture in the development of modern logic. In his 1908 seminal paper, Russell outlined a system, soon to become that of the Principia Mathematicae, whose main goal was the solution of the logical paradoxes, both semantic and settheoretic. Russell did not distinguish between the two and his theory of types was designed to solve both kinds in the same uniform way. Set theoreticians, however, were content (...) to treat only the set-theoretic paradoxes, putting aside the semantic ones as a non-mathematical concern. This separation was explicitly proposed, eighteen years after Russell’s paper, by Ramsey, though he, like Russell, advocated a system that addresses both kinds. Since then, the semantic paradoxes have been viewed within the perspective of the theory of truth, where they have occupied a respectable niche, but one of rather specialized interest. (shrink)

The aim of this paper is to show that in order to make sense of the ascription of truth and falsity to the things we say it is essential to acknowledge a divergence between two basic intuitions. According to one of them it is plausible to talk of what is said as what the speaker has in mind. According to the other it is plausible to talk of what is said as the bearer of truth or falsity. The paper presents (...) three cases in which these two intuitions seem not to coincide, and shows how this lack of coincidence can be accounted for in terms of underspecification. (shrink)

. According to John Buridan, the time for which a statement is true is underdetermined by the grammatical form of the sentence – the intention of the speaker is required. As a consequence, truth-bearers are not sentence types, nor sentence tokens plus facts of the context of utterance, but statements. Statements are also the bearers of logical relations, since the latter can only be established among entities having determined truth-conditions. This role of the intention of the speaker in the determination (...) of what is said by an utterance is not isolated in medieval semantics. (shrink)

The aim of the paper is to formulate rules of inference for the predicate 'is true' applied to sentences. A distinction is recognised between (ordinary) truth and definite truth and consequently between two notions of validity, depending on whether truth or definite truth is the property preserved in valid arguments. Appropriate sets of rules of inference governing the two predicates are devised. In each case the consequence relation is in harmony with the respective predicate. Particularly appealing is a set of (...) ND rules for ordinary truth in which premises and assumptions play different roles, premises being taken to assert definite truth, assumptions to suppose truth. This set of rules can be said to capture everyday reasoning with truth. Also presented are formal characterisations, in the meta-language and in the object language, of paradoxical and 'truth teller'-like sentences. (shrink)

Section 1 discerns ambiguity in the word “truth”, observing that the term is used most naturally in reference to truth-bearers rather than truth-makers. Focusing on truths-as-truth-bearers, then, it would appear that alethic realism conflicts with metaphysical realism as naturalistically construed. Section 2 discerns ambiguity in the purporting of truth (as in assertion), conjecturing that all expressions, not just those found in traditionally recognized opaque contexts, can be read intensionally (as well, perhaps, as extensionally). For instance, we would not generally want (...) to say that “The Matterhorn is 4,500 m high” expresses the same truth as “The Matterhorn is 14763.7795276 feet high” (or that it is true in the same range of utterance contexts), even though the two are extensionally equivalent. The reason is that they express different intensions. (shrink)

Thesis: Such things as beliefs, statements, assertions, remarks, hypotheses, and theories are those things that are true or false . (Example: we do say such things as "Her belief that her mother had phoned was false." Or, "His assertion that Alberta is smaller than British Columbia is true.").

In this paper I consider two strategies for providing tenseless truth-conditions for tensed sentences: the token-reflexive theory and the date theory. Both theories have faced a number of objections by prominent A-theorists such as Quentin Smith and William Lane Craig. Traditionally, these two theories have been viewed as rival methods for providing truth-conditions for tensed sentences. I argue that the debate over whether the token-reflexive theory or the date theory is true has arisen from a failure to distinguish between conditions (...) for the truth of tensed tokens and conditions for the truth of propositions expressed by tensed tokens. I demonstrate that there is a true formulation of the token-reflexive theory that provides necessary and sufficient conditions for the truth of tensed tokens, and there is a true formulation of the date theory that provides necessary and sufficient conditions for the truth of propositions expressed by tensed tokens. I argue that once the views are properly formulated, the A-theorist’s objections fail to make their mark. However, I conclude by claiming that even though there is a true formulation of the token-reflexive theory and a true formulation of the date theory, the New B-theory nonetheless fails to provide a complete account of the truth and falsity of tensed sentences.

This paper examines the potential for abstracting propositions – an as yet untested way of defending the realist thesis that propositions as abstract entities exist. I motivate why we should want to abstract propositions and make clear, by basing an account on the neo-Fregean programme in arithmetic, what ontological and epistemological advantages a realist can gain from this. I then raise a series of problems for the abstraction that ultimately have serious repercussions for realism about propositions in general. I first (...) identify problems about the number of entities able to be abstracted using these techniques. I then focus on how issues of language relativity result in problems akin to the Caesar problem in arithmetic by exposing circularity and modal concern over the status of the criterion of identity for propositions.

A notion of truth as applicable to events of assertoric use ( utterances ) of a sentence token is arguably presupposed and required by our evaluative practices of the use of language. The truth of an utterance seems clearly to depend on what the utterance says . This fundamental dependence seems in turn to be captured by the schema that, if an utterance u says that P , then u is true iff P . Such a schema may thus be (...) thought to constitute a suitable basis for an adequate theory of utterance truth, so much so that it seems straightforwardly to avoid the problems arising from context dependence and the semantic paradoxes which notoriously beset theories of utterance truth based on a simple disquotational schema. The paper argues that appearances are deceptive in both cases. On the one hand, the schema cannot allow for plausible if not uncontroversial non-indexical forms of context dependence, arising from the possibility that what an utterance says can be the case or not relative to different situations and that the truth of an utterance u of a sentence φ arguably depends on the truth of φ at the situation "associated" with u . On the other hand, a quantified utterance-truth variation on the liar paradox shows that the schema entails some consequence φ and at the same time the untruth of any utterance of φ; moreover, a resilient quantified propositional variation on the contingent liar paradox is offered, which only relies on resources usually employed by theories of utterance truth based on the schema.
