Fregeans follow Frege in accepting informativeness and substitution failure as reliable criteria for the existence of senses as objects of thought. In this paper I show that if we accept this, we must also accept the existence of an infinite hierarchy of senses as objects of thought. This is a bad result since it turns Fregeanism into a doctrine according to which object-related thoughts either have an infinite number of objects as contents or none at all. This shows, against the (...) Fregean, that senses cannot themselves be constituents of thought. Los fregeanos aceptan, siguiendo a Frege, que los criterios de informatividad y falla de sustitución son guías confiables de la existencia de sentidos como objetos del pensamiento. En este artículo muestro que si aceptamos esta tesis también debemos aceptar la existencia de una jerarquía infinita de sentidos como objetos del pensamiento. Esta es una mala consecuencia pues convierte al fregeanismo en una doctrina según la cual los pensamientos dirigidos a objetos o bien tienen un número infinito de objetos como contenido o ninguno. Esto muestra, contra los fregeanos, que los sentidos no pueden ellos mismos ser objeto del pensamiento. (shrink)

Kripke’s puzzle has puts pressure on the intuitive idea that one can believe that Superman can fly without believing that Clark Kent can fly. If this idea is wrong then many theories of belief and belief ascription are built from faulty data. I argue that part of the proper analysis of Kripke’s puzzle refutes the closure principles that show up in many important arguments in epistemology, e.g., if S is rational and knows that P and that P entails Q, then (...) if she considers these two beliefs and Q, then she is in a position to know that..

These days the two most popular approaches to belief ascription are Millianism and Contextualism. The former approach is inconsistent with the existence of ordinary Frege cases, such as Lois believing that Superman flies while failing to believe that Clark Kent flies. The Millian holds that the only truth-conditionally relevant aspect of a proper name is its referent or extension. Contextualism, as I will define it for the purposes of this essay, includes all theories according to which ascriptions of the form (...) ‘S believes that a is F’ and ‘S believes that b is F’, where ‘a’ and ‘b’ are coreferential proper names, may, depending on the context, differ in truth-value even though in those very contexts each ascription relates the same believer to the very same proposition. What the two theories have in common is the claim that names are Millian. What separates the two theories is what they say about belief contexts. In this essay I prove that Millianism is true, Contextualism is true, or our intuitions regarding belief ascriptions are hopelessly inaccurate. As a consequence, my argument is a proof that either names and many general terms are Millian or our intuitions regarding belief ascriptions are hopelessly inaccurate. (shrink)

King develops a syntax-based account of propositions based on the idea that propositional unity is grounded in the syntactic structure of the sentence. This account faces two objections: a Benacerraf objection and a grain-size objection. I argue that the syntax-based account survives both objections, as they have been put forward in the existing literature. I go on to show, however, that King equivocates between two distinct notions of ‘propositional structure ’ when explaining his account. Once the confusion is resolved, it (...) is clear that the syntax-based account suffers from both Benacerraf and grain-size problems after all. I conclude by showing that King's account can be revised to avoid these problems, but only if it abandons its motivating idea that it is syntax that unifies the proposition. (shrink)

For sentences such as (1), "Columbus knows that the sea is unpredictable", there is a face-value theory, according to which ‘that’-clauses are singular terms denoting propositions. Famously, Prior raised an objection to the theory, but defenders of the face-value theory such as Forbes, King, Künne, Pietroski and Stanley urged that the objection could be met by maintaining that in (1) ‘to know’ designates a complex relation along the lines of being in a state of knowledge having as content. Is the (...) theory safe, then? The aim of this paper is to show that a new problem for the theory arises if we consider attributions of skills, knacks, propensities and abilities. (shrink)

According to neo-Russellianism, in a sentence such as John believes that Mont Blanc is 4000 m high, any other proper name co-referring with Mont Blanc can be substituted for it without any change in the proposition expressed. Prima facie, our practice of translation shows that this cannot be correct. We will then show that neo-Russellians have a way out of this problem, which consists in holding that actual translations are not a matter of semantics, but also make an attempt at (...) preserving some pragmatic features of the sentences to be translated. We then turn to translations that only preserve the semantic characteristics of the sentences and we argue that, although these translations are unable to show that neo-Russellianism is incorrect, they still show that it relies on some theses that seem to have no justification, apart from saving neo-Russellianism itself.

This paper is an investigation of the general logic of "identifications", claims such as 'To be a vixen is to be a female fox', 'To be human is to be a rational animal', and 'To be just is to help one's friends and harm one's enemies', many of which are of great importance to philosophers. I advocate understanding such claims as expressing higher-order identity, and discuss a variety of different general laws which they might be thought to obey. [New version: (...) Nov. 4th, 2016].

Many competent speakers initially judge that (i) is true and (ii) isfalse, though they know that (iii) is true. (i) Superman leaps more tallbuildings than Clark Kent. (ii) Superman leaps more tall buildings thanSuperman. (iii) Superman is identical with Clark Kent. Semanticexplanations of these intuitions say that (i) and (ii) really can differin truth-value. Pragmatic explanations deny this, and say that theintuitions are due to misleading implicatures. This paper argues thatboth explanations are incorrect. (i) and (ii) cannot differ intruth-value, yet (...) the intuitions are not due to implicatures, but ratherto mistakes in evaluating (i) and (ii). (shrink)

Variabilism is the view that proper names (like pronouns) are semantically represented as variables. Referential names, like referential pronouns, are assigned their referents by a contextual variable assignment (Kaplan 1989). The reference parameter (like the world of evaluation) may also be shifted by operators in the representation language. Indeed verbs that create hyperintensional contexts, like ‘think’, are treated as operators that simultaneously shift the world and assignment parameters. By contrast, metaphysical modal operators shift the world of assessment only. Names, being (...) variables, refer rigidly in the latter merely intensional contexts, but may vary their reference in hyperintensional contexts. This conforms to the intuition that the content of attitude ascriptions encapsulates referential uncertainty. Furthermore, names in hyperintensional contexts are ambiguous between de re* and de dicto* interpretations. This fact is used to account for asymmetric mistaken identity attributions (for example, Biron thinks Katherine is Rosaline, but he doesn’t think Rosaline is Katherine). -/- The variable theory compares favourably with its alternatives, including Millianism and descriptivism. Millians cannot account for the behaviour of names in hyperintensional contexts, while descriptivists cannot generate a necessary contrast between intensional and hyperintensional contexts. No other theory can capture the facts pertaining to the existentially bound use of names. (shrink)

Millianism is a thesis in philosophy of language that the meaning of a proper name is simply its referent. Millianism faces certain puzzles called Frege's Puzzles. Some Millians defend the view by appealing to a metaphysics of belief that involves Ways of Believing. In the first part of this paper, I argue that ethical naturalists can adopt this Millian strategy to resist Moore’s Open Question argument. While this strategy of responding to the Open Question Argument has already appeared in the (...) literature, I show that the Millian strategy can be easily extended to other versions of the Open Question Argument that are alleged to be stronger than the original formulation. The allegedly stronger versions of the Open Question Argument are not straightforwardly Frege's Puzzles, but they still have analogue versions that have been presented against Millianism. What the Ways Millian can say against those analogue versions can easily be applied to these other versions of the Open Question Argument. (shrink)

I wish first to motivate very briefly two points about the kind of context sensitive semantics needed for attitude reports, namely that reports are about referents and about mental representations; then I will compare two proposals for treating the attitudes, both of which capture the two points in question.

According to Russellianism (or Millianism), the two sentences ‘Ralph believes George Eliot is a novelist’ and ‘Ralph believes Mary Ann Evans is a novelist’ cannot diverge in truth-value, since they express the same proposition. The problem for the Russellian (or Millian) is that a puzzle of Kaplan’s seems to show that they can diverge in truth-value and that therefore, since the Russellian holds that they express the same proposition, the Russellian view is contradictory. I argue that the standard Russellian appeal (...) to “ways of thinking” or “propositional guises” is not necessary to solve the puzzle. Rather than this retrograde concession to Fregeanism, appeal should be made to second-order belief. The puzzle is solved, and the contradiction avoided, by maintaining that both sentences are indeed true in addition to the sentence ‘Ralph (mistakenly) believes that he does not believe Mary Ann Evans/George Eliot is a novelist’.

In his famous essay, "A Puzzle About Belief," Saul Kripke poses a puzzle regarding belief. In this paper I shall first describe Kripke's puzzle. Second, I shall introduce and examine five positions one might take in attempting to solve Kripke's Puzzle. In so doing, I shall show why each of these attempts fails to solve Kripke's Puzzle. The significance of this analysis is that if Kripke's Puzzle remains unresolved, then (as Kripke himself claims) the normal apparatus for belief ascription needs (...) rethinking. (shrink)

The objects of credence are the entities to which credences are assigned for the purposes of a successful theory of credence. I use cases akin to Frege's puzzle to argue against referentialism about credence : the view that objects of credence are determined by the objects and properties at which one's credence is directed. I go on to develop a non-referential account of the objects of credence in terms of sets of epistemically possible scenarios.

Is conceptual analysis required for reductive explanation? If there is no a priori entailment from microphysical truths to phenomenal truths, does reductive explanation of the phenomenal fail? We say yes . Ned Block and Robert Stalnaker say no.

In this paper, I argue that there are universals. I begin (Sect. 1) by proposing a sufficient condition for a thing’s being a universal. I then argue (Sect. 2) that some truths exist necessarily. Finally, I argue (Sects. 3 and 4) that these truths are structured entities having constituents that meet the proposed sufficient condition for being universals.

Scott Soames has recently argued that traditional accounts of propositions as n-tuples or sets of objects and properties or functions from worlds to extensions cannot adequately explain how these abstract entities come to represent the world. Soames’ new cognitive theory solves this problem by taking propositions to be derived from agents representing the world to be a certain way. Agents represent the world to be a certain way, for example, when they engage in the cognitive act of predicating, or cognizing, (...) an act that takes place during cognitive events, such as perceiving, believing, judging and asserting. On the cognitive theory, propositions just are act types involving the act of predicating and certain other mental operations. This theory, Soames argues, solves not only the problem of how propositions come to represent but also a number of other difficulties for traditional theories, including the problem of de se propositions and the problems of accounting for how agents are capable of grasping propositions and how they come to stand in the relation of expression to sentences. I argue here that Soames’ particular version of the cognitive theory makes two problematic assumptions about cognitive operations and the contents of proper names. I then briefly examine what can count as evidence for the nature of the constituents of the cognitive operation types that produce propositions and argue that the common nature of cognitive operations and what they operate on ought to be determined empirically in cross-disciplinary work. I conclude by offering a semantics for cognitive act types that accommodates one type of empirical evidence. (shrink)

The aim of this paper is to survey a number of features which are constitutive of the Millian account of attitude-ascription and which I take to be irremediably defective. The features in question, some of which have not been fully appreciated, relate mainly to the failure of that account to accommodate certain fundamental aspects of our ordinary practise of attitude attribution. I take it that one’s definitive method of assessment of a given semantical theory consists in checking out whether or (...) not the theory is able to accommodate our pre-theoretical linguistic intuitions; to use Keith Donnellan’s phrase, such intuitions are the bottom line in philosophical argumentation about language. And I argue that the Millian appeal to modes of presentation taken both as semantically irrelevant and external to the singular contents believed, known, etc., as well as the associated pragmatic strategy employed to discard our ground-floor judgements, are insufficient to palliate the manifest implausibility of a number of Millian descriptions of our attitudes, especially descriptions of our second-order attitudes.

This paper discusses two notational variance views with respect to indexical singular reference and content: the view that certain forms of Millianism are at bottom notational variants of a Fregean theory of reference, the Fregean Notational Variance Claim; and the view that certain forms of Fregeanism are at bottom notational variants of a direct reference theory, the Millian Notational Variance Claim. While the former claim rests on the supposition that a direct reference theory could be easily turned into a particular (...) version of a neo-Fregean one by showing that it is bound to acknowledge certain senselike entities, the latter claim is based upon the supposition that a neo-Fregean theory could be easily turned into a particular version of a Millian one by showing that De Re senses are theoretically superfluous and hence eliminable. The question how many accounts of singular reference and content are we confronted with here — Two different (and mutually antagonistic) theories? Or just two versions of what is in essence the same theory? — is surely of importance to anyone interested in the topic. And this question should be answered by means of a careful assessment of the soundness of each of the above claims. Before trying to adjudicate between the two accounts, one would naturally want to know whether or not there are indeed two substantially disparate accounts. Grosso modo, if the Fregean Claim were sound then we would have a single general conception of singular reference to deal with, viz. Fregeanism; likewise, if the Millian Claim were sound we would be facing a single general conception of singular reference, viz. Millianism. My view is that both the Fregean Notational Variance Claim and its Millian counterpart are wrong, though naturally on different grounds. I have argued elsewhere that the Fregean Notational Variance Claim - considered in its application to the semantics of propositional-attitude reports involving proper names — is unsound. I intend tosupplement in this paper such a result by trying to show that the Millian Claim - taken in its application to the semantics of indexical expressions — should also be rated as incorrect. I focus on a certain set of arguments for the Millian Claim, arguments which I take as adequately representing the general outlook of the Millian theorist with respect to neo-Fregeanism about indexicals and which involve issues about the cognitive significance of sentences containing indexical terms.

The Nature and Structure of Content is a lucid, stimulating and occasionally frustrating book about the metaphysics of propositions. King is a realist about propositions, and he assumes throughout that a viable theory must individuate them more finely than sets of possible worlds. His aim in the first three chapters is to motivate an account in which propositions have constituent structure, akin to and dependent on the structure of the sentences that express them. The following chapters defend the use of (...) propositions in semantics against a variety of objections, and in the seventh and final chapter King presents a new solution to the old paradox of analysis. With little exception, the arguments in these later chapters are rigorous and compelling, but being largely independent of the account developed in the preceding chapters, the book feels somewhat disjointed. Here I pass over these provocative vignettes to deal with the main action, the account of propositions.According to tradition, propositions are things expressed by declarative sentences, bearers of alethic and modal properties, and objects of belief and other psychological attitudes. The idea that propositions have constituent structure, mirroring somehow the sentences that express them, comes down to us from Frege . More recently, the idea has been adopted by Kaplan and figures prominently in ‘Russellian’ semantic theories of Salmon , Soames and others. The big debate in recent philosophy of language focuses on the identity of propositional constituents: are they senses, as in Frege? Or the things linguistic expressions designate, as in Russellian theories? Though his sympathies plainly lie with the Russellians, King remains officially neutral on this dispute, focusing instead on the question of structure itself.Structured propositions are often represented as ….

In his book Semantic Relationism, Kit Fine propounds an original and sophisticated semantic theory called ‘semantic relationism’ or ‘relational semantics’, whose peculiarity is the enrichment of Kaplan’s, Salmon’s and Soames’ Russellian semantics (more specifically, the semantic content of simple sentences and the truth-conditions of belief reports) with coordination, “the very strongest relation of synonymy or being semantically the same”. In this paper, my goal is to shed light on an undesirable result of semantic relationism: a report like “Tom believes that (...) Cicero is bald and Tom does not believe that Tully is bald” is correct according to Fine’s provided truth-conditions of belief reports, but its semantic content is (very likely) a contradiction. As I will argue in the paper, even the resort to the notion of token proposition, introduced in Fine’s recent article “Comments on Scott Soames’ ‘Coordination Problems’”, does not suffice to convincingly eliminate the contradiction; moreover, it raises new difficulties.

In his article “Opacity” (1986), David Kaplan propounded a counterexample to the the- sis, defended by Quine and known as Quine’s Theorem, that establishes the illegitimacy of quantifying from outside into a position not open to substitution. He ingeniously built his counterexample using Quine’s own philosophical material and novel devices, arc quotes and $entences. The present article offers detailed analysis and critical discus- sion of Kaplan’s counterexample and proposes a reasonable reformulation of Quine’s Theorem that bypasses both this counterexample and (...) another, in the author’s opinion, more persuasive counterexample, also discussed in this paper and somehow implicit in “Opacity”, which involves Russellian propositions instead of the Quinean apparatus.

Although much has been written about the truth-conditions of de re attitude reports, little attention has been paid to certain ‘ultra-liberal’ uses of those reports. We believe that if these uses are legitimate, then a number of interesting consequences for various theses in philosophical semantics follow. The majority of the paper involves describing these consequences. In short, we argue that, if true, ultra-liberal reports: bring counterexamples to a popular approach to de re attitude ascriptions, which we will call ‘descriptivism’; and (...) combine with independently plausible principles about the logic of belief to imply that subjects can achieve omniscience about what exists from the armchair. Although we are not committed to the view that ultra-liberal reports are false, in the final part of the paper we discuss the prospects of pursuing a line according to which the acceptability of such reports ought not be taken at face value. We conclude by arguing that those who are sympathetic with this move might have reason to doubt the truth of an even broader class of acceptable de re attitude reports, namely those that have been taken to undermine orthodox accounts of de re attitude ascriptions.

Departing from the dominant theories of Frege, Russell and Mill, Kit Fine has sketched a novel solution to Frege’s puzzle in his book Semantic Relationism. In this article, I briefly discuss the puzzle in its various forms and the attempted solutions of Frege and Russell. I then explicate the essential features of the new theory and critically appraise the mechanism suggested by Fine to solve the puzzle. I show that Semantic Relationism fails to address the concerns raised in the puzzle.

Semanticists face substitution challenges even outside of contexts commonly recognized as opaque. Jennifer M. Saul has drawn attention to pairs of simple sentences - her term for sentences lacking a that-clause operator - of which the following are typical: -/- (1) Clark Kent went into the phone booth, and Superman came out. (1*) Clark Kent went into the phone booth, and Clark Kent came out. -/- (2) Superman is more successful with women than Clark Kent. (2*) Superman is more successful (...) with women than Superman. -/- She challenges us to explain why the upper and lower sentences in each pair differ, or at least appear to differ, in their truth-values and hence truth-conditions. This appearance of substitution failure is inherently puzzling. Moreover, it is taken by Saul to generate a dilemma for anyone hostile to direct reference accounts of that-clause constructions. Direct reference theorists regard the appearance of substitution failure in that-clause contexts as mere appearance, to be dealt with pragmatically rather than semantically. -/- Critics of such accounts need to say something about simple-sentence cases. If they choose to allow that intuitions of substitution failure can be over-ridden and explained away pragmatically in simple-sentence cases but not in that-clause cases, they lay themselves open to the charge of operating a double standard. But if they do not choose this option, they must offer a semantic explanation of apparent substitution failure in simple-sentence cases - no easy task, it turns out. Other respondents to Saul's challenge have sought to provide elaborate semantic treatments. In contrast, this paper proposes a far simpler pragmatic explanation of intuitions of substitution failure in simple sentences, an explanation that deploys no more resources than are to be found in Grice's 'Logic and Conversation'. Ironically, this proposal turns out to be incompatible with a direct reference perspective. So if it is, as I maintain, the most plausible treatment of simple-sentence cases available, Saul's initial thought gets turned around 180 degrees: the phenomenon she has drawn attention to ends up representing a challenge to supporters of direct reference theories.

This essay concerns the question of how we make genuine epistemic progress through conceptual analysis. Our way into this issue will be through consideration of the paradox of analysis. The paradox challenges us to explain how a given statement can make a substantive contribution to our knowledge, even while it purports merely to make explicit what one’s grasp of the concept under scrutiny consists in. The paradox is often treated primarily as a semantic puzzle. However, in “Sect. 1” I argue (...) that the paradox raises a more fundamental epistemic problem, and in “Sects.1 and 2” I argue that semantic proposals—even ones designed to capture the Fregean link between meaning and epistemic significance—fail to resolve that problem. Seeing our way towards a real solution to the paradox requires more than semantics; we also need to understand how the process of analysis can yield justification for accepting a candidate conceptual analysis. I present an account of this process, and explain how it resolves the paradox, in “Sect. 3”. I conclude in “Sect. 4” by considering the implications for the present account concerning the goal of conceptual analysis, and by arguing that the apparent scarcity of short and finite illuminating analyses in philosophically interesting cases provides no grounds for pessimism concerning the possibility of philosophical progress through conceptual analysis.

The topic of this article is the ontology of practical reasons. We draw a critical comparison between two views. According to the first, practical reasons are states of affairs; according to the second, they are propositions. We first isolate and spell out in detail certain objections to the second view that can be found only in embryonic form in the literature – in particular, in the work of Jonathan Dancy. Next, we sketch possible ways in which one might respond to (...) each one of these objections. A careful evaluation of these complaints and responses, we argue, shows that the first view is not as obviously compelling as it is thought by Dancy. Indeed, it turns out that the view that practical reasons are propositions is by no means unworkable and in fact, at least under certain assumptions, explicit considerations can be made in favour of a propositional construal of reasons.

This paper explores the nature of the concept of truth. It does not offer an analysis or definition of truth, or an account of how it relates to other concepts. Instead, it explores what sort of concept truth is by considering what sorts of thoughts it enables us to think. My conclusion is that truth is a part of each and every propositional thought. The concept of truth is therefore best thought of as the ability to token propositional thoughts. I (...) explore what implications this view has for existing accounts of concepts, and argue that truth is a concept unlike any other. (shrink)

This paper explores the relationship between Hume's Prinicple and Basic Law V, investigating the question whether we really do need to suppose that, already in Die Grundlagen, Frege intended that HP should be justified by its derivation from Law V.

The new theory of reference has won popularity. However, a number of noted philosophers have also attempted to reply to the critical arguments of Kripke and others, and aimed to vindicate the description theory of reference. Such responses are often based on ingenious novel kinds of descriptions, such as rigidified descriptions, causal descriptions, and metalinguistic descriptions. This prolonged debate raises the doubt whether different parties really have any shared understanding of what the central question of the philosophical theory of reference (...) is: what is the main question to which descriptivism and the causal-historical theory have presented competing answers. One aim of the paper is to clarify this issue. The most influential objections to the new theory of reference are critically reviewed. Special attention is also paid to certain important later advances in the new theory of reference, due to Devitt and others. (shrink)

This paper examines "moderate modal skepticism", a form of skepticism about metaphysical modality defended by Peter van Inwagen in order to blunt the force of certain modal arguments in the philosophy of religion. Van Inwagen’s argument for moderate modal skepticism assumes Yablo's (1993) influential world-based epistemology of possibility. We raise two problems for this epistemology of possibility, which undermine van Inwagen's argument. We then consider how one might motivate moderate modal skepticism by relying on a different epistemology of possibility, which (...) does not face these problems: Williamson’s (2007: ch. 5) counterfactual-based epistemology. Two ways of motivating moderate modal skepticism within that framework are found unpromising. Nevertheless, we also find a way of vindicating an epistemological thesis that, while weaker than moderate modal skepticism, is strong enough to support the methodological moral van Inwagen wishes to draw.

Over the past fifty years the philosophy of language and mind has been dominated by a nondescriptivist approach to content and reference. This book attempts to recast and systematize that approach by offering an indexical model in terms of mental files. According to Recanati, we refer through mental files, the function of which is to store information derived through certain types of contextual relation the subject bears to objects in his or her environment. The reference of a file is determined (...) relationally, not satisfactionally, so a file is not to be equated to the body of (mis-)information it contains. Mental files are the mental equivalent of singular terms, and the reference of linguistic expressions is inherited from that of the files we associate with them. On this approach, mental files, the vehicles of singular thought, do all the work of so-called 'modes of presentation' in Fregean and neo-Russellian theories. (shrink)

This paper defends the claim that although ‘Superman is Clark Kent and some people who believe that Superman flies do not believe that Clark Kent flies’ is a logically inconsistent sentence, we can still utter this sentence, while speaking literally, without asserting anything false. The key idea is that the context-sensitivity of attitude reports can be - and often is - resolved in different ways within a single sentence.

Revised and reprinted in Handbook of Philosophical Logic, volume 10, Dov Gabbay and Frans Guenthner (eds.), Dordrecht: Kluwer, (2003). -- Two sorts of property theory are distinguished, those dealing with intensional contexts property abstracts (infinitive and gerundive phrases) and proposition abstracts (‘that’-clauses) and those dealing with predication (or instantiation) relations. The first is deemed to be epistemologically more primary, for “the argument from intensional logic” is perhaps the best argument for the existence of properties. This argument is presented in the (...) course of discussing generality, quantifying-in, learnability, referential semantics, nominalism, conceptualism, realism, type-freedom, the first-order/higher-order controversy, names, indexicals, descriptions, Mates’ puzzle, and the paradox of analysis. Two first-order intensional logics are then formulated. Finally, fixed-point type-free theories of predication are discussed, especially their relation to the question whether properties may be identified with propositional functions. (shrink)

Esta enciclopédia abrange, de uma forma introdutória mas desejavelmente rigorosa, uma diversidade de conceitos, temas, problemas, argumentos e teorias localizados numa área relativamente recente de estudos, os quais tem sido habitual qualificar como «estudos lógico-filosóficos». De uma forma apropriadamente genérica, e apesar de o território teórico abrangido ser extenso e de contornos por vezes difusos, podemos dizer que na área se investiga um conjunto de questões fundamentais acerca da natureza da linguagem, da mente, da cognição e do raciocínio humanos, bem (...) como questões acerca das conexões destes com a realidade não mental e extralinguística. A razão daquela qualificação é a seguinte: por um lado, a investigação em questão é qualificada como filosófica em virtude do elevado grau de generalidade e abstracção das questões examinadas (entre outras coisas); por outro, a investigação é qualificada como lógica em virtude de ser uma investigação logicamente disciplinada, no sentido de nela se fazer um uso intenso de conceitos, técnicas e métodos provenientes da disciplina de lógica. O agregado de tópicos que constitui a área de estudos lógico-filosóficos é já visível, pelo menos em parte, no Tractatus Logico-Philosophicus de Ludwig Wittgenstein, uma obra publicada em 1921. E uma boa maneira de ter uma ideia sinóptica do território disciplinar abrangido por esta enciclopédia, ou pelo menos de uma porção substancial dele, é extrair do Tractatus uma lista dos tópicos mais salientes aí discutidos; a lista incluirá certamente tópicos do seguinte género, muitos dos quais se podem encontrar ao longo desta enciclopédia: factos e estados de coisas; objectos; representação; crenças e estados mentais; pensamentos; a proposição; nomes próprios; valores de verdade e bivalência; quantificação; funções de verdade; verdade lógica; identidade; tautologia; o raciocínio matemático; a natureza da inferência; o cepticismo e o solipsismo; a indução; as constantes lógicas; a negação; a forma lógica; as leis da ciência; o número.

This book combines insights from philosophy and linguistics to develop a novel framework for theorizing about linguistic meaning and the role of context in interpretation. A key innovation is to introduce explicit representations of context — assignment variables — in the syntax and semantics of natural language. The proposed theory systematizes a spectrum of “shifting” phenomena in which the context relevant for interpreting certain expressions depends on features of the linguistic environment. Central applications include local and nonlocal contextual dependencies with (...) quantifiers, attitude ascriptions, conditionals, questions, and relativization. The result is an innovative, philosophically informed compositional semantics compatible with the truth-conditional paradigm. (shrink)

The book presents the various theories of intentionality from Brentano and Husserl to present day (1997) theories on mental content, narrow and broad.

This chapter investigates the conflict between thought and speech that is inherent in lying. This is the conflict of saying what you think is false. The chapter shows how stubbornly saying what you think is false resists analysis. In traditional analyses of lying, saying what you think is false is analyzed in terms of saying something and believing that it is false. But standard cases of unconscious or divided belief challenge these analyses. Classic puzzles about belief from Gottlob Frege and (...) Saul Kripke show that suggested amendments involving assent instead of belief do not fare better. I argue that attempts to save these analyses by appeal to guises or Fregean modes of presentation will also run into trouble. I then consider alternative approaches to untruthfulness that focus on (a) expectations for one’s act of saying/asserting and (b) the intentions involved in one’s act of saying/asserting. Here I introduce two new kinds of case, which I call “truth serum” and “liar serum” cases. Consideration of these cases reveals structural problems with intention- and expectation-based approaches as well. Taken together, the string of cases presented suggests that saying what you think is false, or being untruthful, is no less difficult and interesting a subject for analysis than lying itself. Tackling the question of what it is to say what you think is false illuminates ways in which the study of lying is intertwined with fundamental issues in the nature of intentional action. (shrink)

Why is two-dimensional semantics important? One can think of it as the most recent act in a drama involving three of the central concepts of philosophy: meaning, reason, and modality. First, Kant linked reason and modality, by suggesting that what is necessary is knowable a priori, and vice versa. Second, Frege linked reason and meaning, by proposing an aspect of meaning (sense) that is constitutively tied to cognitive signi?cance. Third, Carnap linked meaning and modality, by proposing an aspect of meaning (...) (intension) that is constitutively tied to possibility and necessity. (shrink)

I develop and argue for a novel theory of the mental state of identity confusion. I also argue that this mental state can corrupt the proper function of singular terms in linguistic communication. Finally, I propose a theory according to which identity confusion should be treated as a the source of a new sort of linguistic performance error, similar to malapropism, slips of the tongue, and so-called intentional obfuscation (inducing false belief by manipulating language in specific ways). -/- Going into (...) a bit more detail, I start by arguing that contemporary analytic philosophy, and philosophy of language in particular, has been dominated by a ‘puzzle-driven’ methodology. This tradition, I claim, seeks to provide a coherent system for describing semantic features of all conceivable cases where a speaker is confused about the identity or distinctness of an object. On my view, identity confusion is a mental state of an agent who either believes falsely that a is identical to b or believes falsely that a is not identical to b. I show how many influential arguments in philosophy – e.g., Kripke on semantic reference and speaker’s reference – are invalidated because of false assumptions about the state of identity confusion. -/- More positively, I assume an ‘explanation-driven’ approach, combining strands in Gricean intentionalism and Ruth Millikan’s teleosemantics. On this view, confused speakers are ‘sub-optimal’: their mental state disrupts the proper function of the relevant singular terms in their idiolects. Furthermore, I flesh out a theoretically fruitful notion of ‘edenic reference,’ which idealizes away from confusion in defining the optimal or stabilizing function of singular terms. I argue that speakers must satisfy certain broadly cognitive constraints if their utterances are to play a role in explaining the maintenance of a practice of using a singular term in a linguistic community.

I propose some rules that regiment substitutions of NPs.

The paper examines Frege’s argument based on the problem of cognitive value. This argument is opposed to Millian semantics on proper names and sustains Frege’s owns proposal. I point out a general flaw in the argument and elucidate the difficulty embodied by the ‘Paderewski’ example. I also defend the relevance of the example from a contention suggested in a recent paper by David Sosa.

Kaplan’s solution to the indexical version of Frege’s Puzzle in terms of the character of linguistic expressions has been greatly influential and much discussed. Many philosophers regard it as being correct, or at least as being on the right track. However, little has been said about how character is supposed to apply to proper names, and how it could account for the name version of the Puzzle. In this paper I want to fill this gap. I sketch some solutions to (...) the name version of Frege’s Puzzle in terms of character, and argue that all of them are flawed in some way: they are either semantically implausible or fail to account for all relevant phenomena.

Approaches to truth and the Liar paradox seem invariably to face a dilemma: either appeal to some sort of hierarchy, or declare apparently perfectly coherent concepts incoherent. But since both options lead to severe expressive restrictions, neither seems satisfactory. The aim of this paper is a new approach, which avoids the dilemma and the resulting expressive restrictions. Previous approaches tend to appeal to some new sort of semantic value for the truth predicate to take. I argue that such approaches inevitably (...) lead to the dilemma in question. In contrast, the present proposal sticks with classical semantic values, but allows the compositional rules associated with these to admit of exceptions. I show how such an approach can be developed systematically. (shrink)

[[This paper appears in my anthology _Philosophy of Mind: Classical and Contemporary Readings_ (Oxford University Press, 2002), pp. 608-633. It is a heavily revised version of a paper first written in 1994 and revised in 1995. Sections 1, 7, 8, and 10 are similar to the old version, but the other sections are quite different. Because the old version has been widely cited, I have made it available (in its 1995 version) at http://consc.net/papers/content95.html.
