The Lockean theory of communication is here defined as the theory that communication takes place when a hearer grasps some sort of mental object, distinct from the speaker's words, that the speaker's words express. This theory contrasts with the view that spoken languages are the very medium of a kind of thought of which overt speech is the most basic form. This article is a critique of some of the most common motives for adopting a Lockean theory of communication. It is not enough that words in some sense express thoughts. It is not enough that animals and prelinguistic infants in some sense think. It is not enough that speakers mean something by what they say or that hearers must understand a speaker's presuppositions. On the contrary, any explanation of how children can learn to communicate in the way the Lockean imagines will presuppose that words can instill beliefs in some way more fundamental than the Lockean theory itself can explain.

"If you turn left at the next corner, you will see a blue house at the end of the street." That sentence -- a conditional -- might be true even though it is possible that you will not see a blue house at the end of the street when you turn left at the next corner. A moving van may block your view; the house may have been painted pink; a crow might swoop down and peck out your eyes. Still, in some contexts, we might ignore these possibilities and correctly assert the conditional. In this book, Christopher Gauker argues that such context-relativity is the key to understanding the semantics of conditionals. Contexts are defined as objective features of the situation in which a conversation takes place, and the semantic properties of sentences -- conditionals included -- are defined in terms of assertibility in a context. One of the primary goals of a theory of conditionals has to be to distinguish correctly between valid and invalid arguments containing conditionals. According to Gauker, an argument is valid if the conclusion is assertible in every context in which the premises are assertible. This runs counter to what Gauker sees as a systematic misreading of the data by other authors, who judge arguments to be invalid if they can think of a context in which the premises are judged true and some other context in which the conclusion is judged false. Different schools of thought on conditionals reflect fundamentally different approaches to semantics. Gauker offers his theory as a motive and test case for a distinctive kind of semantics that dispenses with reference relations and possible worlds.

A number of philosophers have argued that the key to understanding the semantic paradoxes is to recognize that truth is essentially relative to context. All of these philosophers have been motivated by the idea that once a liar sentence has been uttered we can 'step back' and, from the point of view of a different context, judge that the liar sentence is true. This paper argues that this 'stepping back' idea is a mistake that results from failing to relativize truth to context in the first place. Moreover, context-relative liar sentences, such as 'This sentence is not true in any context' present a paradox even after truth has been relativized to context. Nonetheless, the relativization of truth to context may offer us the means to avoid paradox, if we can justifiably deny that a sentence about a context can be true in the very context it is about

The proposition expressed by a sentence is relative to a context. But what determines the content of the context? Many theorists would include among these determinants aspects of the speaker’s intention in speaking. My thesis is that, on the contrary, the determinants of the context never include the speaker’s intention. My argument for this thesis turns on a consideration of the role that the concept of proposition expressed in context is supposed to play in a theory of linguistic communication. To illustrate an alternative approach, I present an original theory of the reference of demonstratives according to which the referent of a demonstrative is the object that adequately and best satisfies certain accessibility criteria. Although I call my thesis zero tolerance for pragmatics, it is not an expression of intolerance for everything that might be called “pragmatics.”.

Recanati takes for granted the conveyance conception of linguistic communica- tion, although it is not very clear exactly where he lies on the spectrum of possible variations. Even if we disavow all such conceptions of linguistic communication, there will be a place for semantic theory in articulating normative concepts such as logical consistency and logical validity. An approach to semantics focused on such normative concepts is illustrated using the example of ““It’’s raining””. It is argued that Recanati’’s conception of semantics as involving the pragmatics of saturation and modulation cannot account for the logical properties of ““It’’s raining”.

The proposition expressed by an utterance of a quantified sentence depends on a domain of discourse somehow determined by the context. How does the context of utterance determine the content of the domain of discourse? Many philosophers would approach this question from the point of view of an expressive theory of linguistic communication, according to which the primary function of language is to enable speakers to convey the propositional contents of their thoughts to hearers. This paper argues that from this point of view there is no persuasive treatment of the determinants of the domain of discourse. The argument focuses on an abnormal case in which the domain the speaker has in mind is not evident to the hearer. In this way the question concerning the determinants of the domain of discourse is used to challenge the expressive theory of communication

The question whether semantics is a normative discipline can be formulated as a question about the meaning of the word “means”. If I assert, “The word ‘gatto’ in Italian means cat,” what have I done? The naturalist about meaning claims that I have asserted that a certain natural relation obtains between Italian speakers’ tokens of “gatto” and cats. Or at least, I have asserted something about the way Italian speakers use the word “gatto”, which way presumably has something to do with cats. The normativist claims, on the contrary, that what I have said is that in speaking Italian one ought to use the word “gatto” in a certain way, which way has something to do with cats. What I have done is endorse a certain proposal about how to use the word, which, if accepted, will have normative force.

Language acquisition is often said to be a process of mapping words into pre-existing concepts. If that is right, then we ought to be able to obtain experimental evidence for the existence of concepts in prelinguistic children. One line of research that attempts to provide such evidence is the work of Paul Quinn, who claims that looking-time results show that four--month old infants form “category representations”. This paper argues that Quinn’s results have an alternative explanation. A distinction is drawn between conceptual thought and the perception of comparative similarity relations, and it is argued that Quinn’s results can be explained in terms of the latter rather than the former

A similarity space is a hyperspace in which the dimensions represent various dimensions on which objects may differ. The similarity space theory of concepts is the thesis that concepts are regions of similarity spaces that are somehow realized in the brain. Proponents of such a theory of concepts include Paul Churchland and Peter Gärdenfors. This paper argues that the similarity space theory of concepts is mistaken because regions of similarity spaces cannot serve as the components of judgments. It emerges that although similarity spaces cannot model concepts, they may model a kind of nonconceptual representation.

For many purposes in pragmatics one needs to appeal to a context of utterance conceived as a set of sentences or propositions. The context of utterance in this sense is often defined as the set of assumptions that the speaker supposes he or she shares with the hearer. I argue by stages that this is a mistake. First, if contexts must be defined in terms of shared assumptions, then it would be preferable to define the context as the set of assumptionsthat the interlocutors really do share. Second, not all shared assumptions belong to the context, because not all are relevant. Third, hearers need not accept every member of the context, because some presuppositions are informative. Finally, presupposition coordination problems show that contexts may have contents that even the speaker does not accept. Contexts, we may conclude, are mind-transcendent. In one sense of the term a "presupposition" is an interlocutor's take on this mind-transcendent context.

Abstract In their book, Holism: A Shopper's Guide, Jerry Fodor and Ernest Lepore fail to distinguish between two kinds of holism. One of these is holism about meaning, which is indeed problematic. The other is holism about translation, which is not so clearly problematic. Moreover, the problem with the first sort is that it renders communication unintelligible, not that it rules out psychological laws. Further, Fodor and Lepore's criticisms of various contemporary holists are based on serious misreadings. In particular, Quine need not accept the conception of statements that they force on him, and Davidson and Dennett do not argue for the principle of charity in the ways Fodor and Lepore suppose. But Fodor and Lepore's question about the provenance of the principle of charity is a good one and deserves an answer

This paper spells out the positive theory sketched at the end of "Against Stepping Back".): According to deflationists, [p] is true is in some sense equivalent to p. The problem that the semantic paradoxes pose for the deflationist is to explicate this equivalence without relying on a semantics grounded in the sort of real reference relations that a deflationist thinks do not exist. More generally, the deflationist is challenged to give an account of logical validity that does not force us to countenance such relations. (The usual model-theoretic definition seems to presuppose that there is some special interpretation, the intended interpretation, such that truth simpliciter is truth on that intended interpretation. So if the deflationist adopts this sort of definition, the deflationist will be challenged to identify the intended interpretation without positing real reference relations.) Fortunately, a precise semantics compatible with the deflationist philosophy can be had as follows: First, we define a context as a certain sort of set constructed from a basis of literals (atomic sentences and negations of atomic sentences). This formal account of contexts has to be supplemented with an account of the conditions under which a structure satisfying the formal definition is the structure of that kind pertinent ot a given conversation. For each syntactic type of sentence, we define the conditions under which a sentence of that type is assertible relative to a context. In particular, we define the conditions under which sentences of the form " [p] is true" are assertible in a context, and we define the conditions under which sentences of the form "[p] is assertible in context G" are assertible in a context. Finally, logical validity is defined as preservation of assertibility in a context. It is demonstrated that this approach to semantics resists the semantic paradoxes.

This is a free book, 165 pages. It is for anyone who has had a solid introductory logic course and wants more. Topics covered include soundness and completeness for first-order logic, Tarski's theorem on the undefinability of truth, Gödel's incompleteness theorems, the undecidability of first-order logic, a smattering of second-order logic, and modal logic (both propositional and quantificational). I wrote it for use in my own course, because I thought I could present the most important results and concepts more clearly than the available textbooks.

This is not a research paper. It is just a handout that I prepared for a course some years ago. It is a presentation of Kripke's theory of truth that I intend to be understandable even to people who have had only a first course in logic. Although elementary, it is completely precise. All the terms are defined and all the proofs (except one trivial induction) are given in detail. I am putting this on the web because I think there are probably a lot of people who want to think about truth and who recognize that they need to know something about Kripke's theory but who are not sure whether they have the necessary background to follow the precise presentations that have been published.

The rule of universal instantiation appears to be subject to counterexamples, although the rule of existential generalization is not subject to the same doubts. This paper is a survey of ways of responding to this problem, both conservative and revisionist. The conclusion drawn is that logical validity should be defined in terms of assertibility in a context rather than in terms of truth on an interpretation. Contexts are here defined, not in terms of the attitudes of the interlocutors, but in terms of the goals of conversation, and assertibility is explained in terms of cooperation.

Jason Stanley has argued that in order to obtain the desired readings of certain sentences, such as “In most of John’s classes, he fails exactly three Frenchmen”, we must suppose that each common noun is associated with a hidden indexical that may be either bound by a higher quantifier phrase or interpreted by the context. This paper shows that the desired readings can be obtained as well by interpreting nouns as expressing relations and without supposing that nouns are associated with hidden indexicals. Stanley’s theory and the present alternative are not equivalent, however. They differ over the status of sentences such as “Every student is happy and some student is not happy”. On Stanley’s theory, this sentence will be true in some contexts, while on the present alternative it will be true in no context. Considerations in favor of the present theory’s verdict on such sentences are presented. The broader question at issue is the correct way to incorporate context-relativity into formal semantics.

I define T-schema deflationism as the thesis that a theory of truth for our language can simply take the form of certain instances of Tarski's schema (T). I show that any effective enumeration of these instances will yield as a dividend an effective enumeration of all truths of our language. But that contradicts Gödel's First Incompleteness Theorem. So the instances of (T) constituting the T-Schema deflationist's theory of truth are not effectively enumerable, which casts doubt on the idea that the T-schema deflationist in any sense has a theory of truth. (The argument in section 2 of "Semantics for Deflationists" supercedes this paper.).
