Jerrold J. Katz often explained his semantic theory by way of an analogy with physical atomism and an attendant analogy with chemistry. In this chapter, I track the origin and uses of these analogies by Katz, both in explaining and defending his decompositional semantic theory, through the various phases of his work throughout his career.

In this paper I argue that there can be genuine (as opposed to merely verbal) disputes about whether a sentence form is logically true or an argument form is valid. I call such disputes ?cases of deviance?, of which I distinguish a weak and a strong form. Weak deviance holds if one disputant is right and the other wrong, but the available evidence is insufficient to determine which is which. Strong deviance holds if there is no fact of the matter. (...) In section 2 I argue that weak deviance need not be trivial and may even be interesting. Section 3 considers what it could mean to say that logic is determined by a theory, especially a theory of meaning, an idea that arises in section 2. In section 4 I discuss the dispute between classical and relevance logicians over entailment and argue that it is a case of strong deviance. Finally, in section 5 I show that the result of the previous section is not absolute but relative to the background logic used in reaching it. (shrink)

The Fodorian central objections to Inferential Role Semantics can be taken to include an ‘Analyticity Challenge’ and a ‘Circularity Challenge’, which are ultimately challenges to IRS explanations of concept possession. In this paper I present inferential role theories, critically examine these challenges and point out two misunderstandings to which they are exposed. I then state in detail a rationalist version of IRS and argue that this version meets head on the Fodorian challenges. If sound, these considerations show that there is (...) no problem of principle in the consideration of IRS as a good candidate for a theory of concepts. (shrink)

In the light of partial understanding, we examine the thesis that concepts are individuated in terms of possession conditions and show that adherents face a fatal dilemma: Either concept-individuating possession conditions include cases of partially understood concepts or not. If yes, possession conditions do not individuate concepts. If no, the thesis is too restricted and lacks a minimally satisfactory level of generalization.

In "Truth and Meaning", Davidson suggested that a truth theory can do the work of a theory of meaning: it can give the meanings of expressions of a language, and can explain the semantic competence of speakers of the language by stating information knowledge of which would suffice for competence. From the start, this program faced certain fundamental objections. One response to these objections has been to supplement the truth theory with additional rules of inference (e.g. from T-sentences to meaning (...) theorems). I argue that these modifications of Davidson's original idea fail to solve the problems with Davidsonian semantics, and that the prospects for a solution to these problems within the Davidsonian framework are dim. A general lesson to be drawn is that Davidsonian theories do not provide a viable alternative to Russellian and Fregean approaches to semantics which recognize the reality of language-independent contents.

The paper offers a new analysis of the difficulties involved in the construction of a general and substantive correspondence theory of truth and delineates a solution to these difficulties in the form of a new methodology. The central argument is inspired by Kant, and the proposed methodology is explained and justified both in general philosophical terms and by reference to a particular variant of Tarski's theory. The paper begins with general considerations on truth and correspondence and concludes with a brief (...) outlook on the "family" of theories of truth generated by the new methodology. (shrink)

Il peut sembler incongru de supposer qu'il y a une identité entre l'histoire de la science et l'histoire d'une idéologie C'est pourtant ce que donne à penser, comme on le verra, une comparaison entre la notion kuhnienne de paradigme et la notion d'idéologie. Une relation a déjà été établie entre les deux notions. Nous croyons qu'elle reste superficielle et ne conduit qu'à une compréhension négative. On pose cette relation pour dire que chez Kuhn le paradigme détermine le comportement de la (...) communauté scientifique à la manière de l'idéologie, au sens péjoratif du terme, c'est-à-dire d'une façon dogmatique, aveugle et passionnée, produisant des décisions irrationnelles et sectaires. Notre intention est d'abord d'expliciter la relation entre la notion kuhnienne de paradigme et la notion d'idéologie. Trois résultats sont visés. En premier lieu, il s'agit de donner plus de signification à cette relation et de la préciser. En second lieu, de contribuer à l'étude du problème de la justification en science, tel qu'il peut se poser à partir de Kuhn. En troisième lieu, de montrer que, dans la mesure où la description de Kuhn est convaincante, et où la relation que nous analysons est fondée, la séparation entre la science et l'idéologie est à repenser.

This essay continues my investigation of `syntactic semantics': the theory that, pace Searle's Chinese-Room Argument, syntax does suffice for semantics (in particular, for the semantics needed for a computational cognitive theory of natural-language understanding). Here, I argue that syntactic semantics (which is internal and first-person) is what has been called a conceptual-role semantics: The meaning of any expression is the role that it plays in the complete system of expressions. Such a `narrow', conceptual-role semantics is the appropriate sort of semantics (...) to account (from an `internal', or first-person perspective) for how a cognitive agent understands language. Some have argued for the primacy of external, or `wide', semantics, while others have argued for a two-factor analysis. But, although two factors can be specified–-one internal and first-person, the other only specifiable in an external, third-person way–-only the internal, first-person one is needed for understanding how someone understands. A truth-conditional semantics can still be provided, but only from a third-person perspective. (shrink)

This paper begins by considering Dummett's justificationist treatment of statements about the past in his book Truth and the Past (2004). Contrary to Dummett's position, there is no way of applying the intuitionistic distinction in the arithmetical case between direct and indirect methods of establishing a content to the case of past-tense statements. Attempts to do so either give the wrong truth conditions, or rely on notions not available to a justificationist position. A better, realistic treatment makes ineliminable use of (...) identity of state in its positive account of understanding of the past tense; this account can also be applied to other subject matters besides the past. A theory is developed of how realists should conceive of the relation between meaning and evidence. Points from this discussion are used in criticism of Wright's minimalist conception of truth. Three grades of possible involvement of truth and reference in a substantive theory of intentional content are distinguished, and reasons are given for thinking that a range of contents involve the highest degree of involvement of reference and truth in their substantive individuation.

The truth-condition theory of meaning is, naturally, thought of an as explanatory theory whose explananda are the meaning facts. But there are at least two deductive arguments that purport to establish the truth of the theory irrespective of its explanatory virtues. This paper examines those arguments and concludes that they succeed.

According to Tarski, a theory of truth for a language L is a theory which logically implies for each sentence S of L a sentence of the form:S is true-in-L if and only if p,where rS1 is replaced by a canonical description of a sentence of L and rp1 is replaced by that sentence if L is contained in the metalanguage or by a translation of S if it is not so contained. Tarski constructed consistent and finitely axiomatized theories of (...) truth for various formal languages and showed how to explicitly define ‘is true in L’ within these theories. We all agree that Tarski's theories of truth have enormous philosophical significance, but there is much less agreement on precisely what that significance consists in. (shrink)

Along with many other languages, English has a relatively straightforward grammatical distinction between mass-occurrences of nouns and their countoccurrences. As the mass-count distinction, in my view, is best drawn between occurrences of expressions, rather than expressions themselves, it becomes important that there be some rule-governed way of classifying a given noun-occurrence into mass or count. The project of classifying noun-occurrences is the topic of Section II of this paper. Section III, the remainder of the paper, concerns the semantic differences between (...) nouns in their mass-occurrences and those in their count-occurrences. As both the name view and the mixed view are, in my opinion, subject to serious difficulties discussed in Section III.1,I defend a version of the predicate view. Traditionally, nouns in their singular count-occurrences are also analyzed as playing the semantic role of a predicate. How, then, does the predicate view preserve the intuitive difference between nouns in their mass- and those in their count-occurrences? I suggest, in Section III.2, that there are different kinds of predicates: mass-predicates, e.g. ‘is hair’, singular count-predicates, e.g. ‘is a hair’, and plural count-predicates, e.g. ‘are hairs’. Mass-predicates and count-predicates, in my view, are not reducible to each other. The remainder of Section III takes a closer look at the differences and interrelations between these different kinds of predicates. Mass-predicates and count-predicates differ from each other truth-conditionally, and these truth-conditional differences turn out to have interesting implications, in particular concerning the part-whole relation and our practices of counting. But mass- and count-predicates are also related to each other through systematic entailment relations; these entailment relations are examined in Section III.4. (shrink)

According to Field’s influential incompleteness objection, Tarski’s semantic theory of truth is unsatisfactory since the definition that forms its basis is incomplete in two distinct senses: (1) it is physicalistically inadequate, and for this reason, (2) it is conceptually deficient. In this paper, I defend the semantic theory of truth against the incompleteness objection by conceding (1) but rejecting (2). After arguing that Davidson and McDowell’s reply to the incompleteness objection fails to pass muster, I argue that, within the constraints (...) of a non-reductive physicalism and a holism concerning the concepts of truth, reference and meaning, conceding Field’s physicalistic inadequacy conclusion while rejecting his conceptual deficiency conclusion is a promising reply to the incompleteness objection.

CRS says that the meanings of expressions of a language or other symbol system or the contents of mental states are determined and explained by the way symbols are used in thinking. According to CRS one.

I give a probabilistic semantics for modal logic in which modal operators function as quantifiers over Popper functions in probabilistic model sets, thereby generalizing Kripke's semantics for modal logic.

There is an incompatibility between the deflationist approach to truth, which makes truth transparent on the basis of an antecedent grasp of meaning, and the traditional endeavour, exemplified by Davidson, to explicate meaning through of truth. I suggest that both parties are in the explanatory red: deflationist lack a non-truth-involving theory of meaning and Davidsonians lack a non-deflationary account of truth. My focus is on the attempts of the latter party to resolve their problem. I look in detail at Davidson's (...) more recent work and suggest that it seeks to articulate a primitive notion of truth that may balance between a notion that collapses into deflationism and one that is wholly subsumed under a general theory of interpretation. I conclude that this tightrope walk is ultimately unsuccessful. Equally, however, some reasons are provided for thinking that deflationism might be equally unsuccessful with its problem. 'Truth or meaning?' remains an open question. (shrink)

Now in a new edition, this volume updates Davidson's exceptional Inquiries into Truth and Interpretation (1984), which set out his enormously influential philosophy of language. The original volume remains a central point of reference, and a focus of controversy, with its impact extending into linguistic theory, philosophy of mind, and epistemology. Addressing a central question--what it is for words to mean what they do--and featuring a previously uncollected, additional essay, this work will appeal to a wide audience of philosophers, linguists, (...) and psychologists.

I discuss and defend two arguments against semantic theories which wish to avoid commitment to propositions. The first holds that on the most plausible semantics of a class of natural language sentences, the truth of sentences in that class requires the existence of propositions; and some sentences in that class are true. The second holds that, on the best understanding of the form of a semantic theory, the truth of a semantic theory itself entails the existence of propositions. Much of (...) the discussion engages Davidsonian alternatives to a propositionalist semantic theory. (shrink)

The theory of concepts advanced in the dissertation aims at accounting for a) how a concept makes successful practice possible, and b) how a scientific concept can be subject to rational change in the course of history. Traditional accounts in the philosophy of science have usually studied concepts in terms only of their reference; their concern is to establish a stability of reference in order to address the incommensurability problem. My discussion, in contrast, suggests that each scientific concept consists of (...) three components of content: 1) reference, 2) inferential role, and 3) the epistemic goal pursued with the concept's use. I argue that in the course of history a concept can change in any of these three components, and that change in one component—including change of reference—can be accounted for as being rational relative to other components, in particular a concept's epistemic goal.This semantic framework is applied to two cases from the history of biology: the homology concept as used in 19th and 20th century biology, and the gene concept as used in different parts of the 20th century. The homology case study argues that the advent of Darwinian evolutionary theory, despite introducing a new definition of homology, did not bring about a new homology concept (distinct from the pre-Darwinian concept) in the 19th century. Nowadays, however, distinct homology concepts are used in systematics/evolutionary biology, in evolutionary developmental biology, and in molecular biology. The emergence of these different homology concepts is explained as occurring in a rational fashion. The gene case study argues that conceptual progress occurred with the transition from the classical to the molecular gene concept, despite a change in reference. In the last two decades, change occurred internal to the molecular gene concept, so that nowadays this concept's usage and reference varies from context to context. I argue that this situation emerged rationally and that the current variation in usage and reference is conducive to biological practice.The dissertation uses ideas and methodological tools from the philosophy of mind and language, the philosophy of science, the history of science, and the psychology of concepts.

Moore's Open Question Arguments are among the most influential arguments in 20th Century metaethical thought. But, surprisingly, there is a fair amount of confusion concerning what the Open Question Arguments actually are, how the Moorean passages should be interpreted, and what they are intended to show. Thus, the early chapters are devoted to clarificatory matters, including the exposing of a variety of contemporary attacks upon Moore's arguments as misguided by indicating where they rest upon faulty interpretations of Moorean passages. Providing (...) what I take to be accurate formulations of Moore's famous arguments, responding to historically important preliminary objections, and, finally, presenting various shortcomings of these arguments constitute the remaining themes of the early chapters. ;Next, I pursue an explanation of what I call the 'Open Question phenomenon': the inclination that many have to endorse Moore's "open question" premises. I survey a variety of popular noncognitivist explanations, arguing that each of them is unsatisfactory. I then present a novel semantic explanation of the phenomenon and use it to construct an augmented Moorean Open Question Argument, one capable of overcoming the shortcomings of Moore's originals. ;The latter chapters are dedicated to an investigation of Moore's preferred normative theory---a version of objective consequentialism. I argue that the standard semantic account of subjunctive conditionals fails to capture the nature of certain subjunctive conditionals relevant to the normative evaluation of alternatives from an objective consequentialist perspective. I then present a modified version of the standard account in an effort to remedy the problem. ;Next, I present a novel objection against all extant versions of objective consequentialism. I then introduce and utilize the concept of an "objective" subjunctive probability in the transformation of a subjective version of consequentialism into an objective version, one capable of dealing with the difficulties posed by the objection. ;I conclude the dissertation with a final chapter in which I defend possibilist versions of consequentialism from a contemporary objection. In doing so, I elucidate a theoretical advantage that possibilist theories have over their subjunctive counterparts. (shrink)

Theory and Reality is about the connection between true theories and the world. A mathematical framefork for such connections is given, and it is shown how that framework can be used to infer facts about the structure of reality from facts about the structure of true theories, The book starts with an overview of various approaches to metaphysics. Beginning with Quine's programmatic "On what there is", the first chapter then discusses the perils involved in going from language to metaphysics. It (...) criticises contemporary intuition-driven metaphysics, comments on naturalistic approaches, and then presents the main proposition put forward in the thesis: we should base metaphysics on model theory. In chapters 2 to 5, mathematical treatments are given of concepts that we need: theories, metaphysics, necessitation and semantics. These are used in chapters 6 and 7 to prove that, seen from a certain informative view point, any true theory will give rise to an isomorphism between that theory and the world. This conclusion is similar to Wittgenstein's in the Tractatus, but differs in that it places the structural relationship on the level of whole theories, rather than single propositions. (shrink)
