Substitutivity in Attitude Ascriptions

A new kind of defense of the Millian theory of names is given, which explains intuitive counter-examples as depending on pragmatic effects of the relevant sentences, by direct application of Grice’s and Sperber and Wilson’s Relevance Theory and uncontroversial assumptions. I begin by arguing that synonyms are always intersubstitutable, despite Mates’ considerations, and then apply the method to names. Then, a fairly large sample of cases concerning names are dealt with in related ways. It is argued that the method, as (...) applied to the various cases, satisfies the criterion of success: that for every sentence in context, it is a counter-example to Millianism to the extent that it has pragmatic effects (matching speakers’ intuitions).

In a review of Frege's Puzzle1, Graeme Forbes makes the claim that Salmon's account of belief might be seen, under certain conditions, as a mere notational variant of a neo-Fregean theory; and thus that such an account might be reduced to a neo-Fregean one simply by rewriting it in terms of Fregean terminology. With a view to supporting his claim, Forbes offers an outline of an account of belief which, according to him, would satisfy the following conditions: (i) it could (...) be directly obtained from Salmon's own analysis by means of a certain set of substitutions, which presumably would not affect the essential features of Salmon's view; (ii) it could naturally be described as Fregean, in the sense that it would preserve, (at least) the spirit of Frege's doctrines, especially his fundamental intuitions about belief. Of course, the upshot of Forbes's argument is that Salmon's theory would not, at bottom, constitute a genuine alternative to a Fregean semantics for belief ascriptions. In this paper I argue to the effect that Forbes's claim is not in general sound. It seems to me that the sort of indirect argument used by Forbes - that of trying to undermine Salmon's theory by showing that it is just a version of a neo-Fregean account - does not provide someone working within a Fregean framework with an adequate strategy to counter Salmon's neo-Russellian views. It would perhaps be better to concentrate a Fregean attack on certain apparently dubious and highly controversial theses and results which are constitutive of Salmon's view, e.g. the counterintuitive character of a substantial set of consequences which follow from his theory of belief, as well as the associated revisionist stand he is forced to take towards our current patterns of speaking about belief.

In this paper, I defend a well-known theory of belief reports from an important objection. The theory is Russellianism, sometimes also called `neo-Russellianism', `Millianism', `the direct reference theory', `the "Fido"-Fido theory', or `the naive theory'. The objection concernssubstitution of co-referring names in belief sentences. Russellianism implies that any two belief sentences, that differ only in containing distinct co-referring names, express the same proposition (in any given context). Since `Hesperus' and `Phosphorus' both refer to the planet Venus, this view implies that (...) all utterances of (1) and.. (shrink)

The semantic puzzles posed by propositional attitude contexts have, since Frege, been understood primarily in terms of certain substitution puzzles. We will take as paradigmatic of such substitution puzzles cases in which two coreferential proper names cannot be intersubstituted salva veritate in the context of an attitude verb. Thus, for example, the following sentences differ in truth value: (1) Lois Lane believes Superman can fly. (2) Lois Lane believes Clark Kent can fly. despite the fact that "Superman" and "Clark Kent" (...) pick out the same individual.1 Equivalently, the following sentence may be true: (3) Lois Lane believes that Superman can fly, but that Clark Kent cannot fly. despite the coreferentiality of the names. (It will at times be convenient to appeal to this conjunctive attitude report in order to fix a single context of utterance.) Substitution failures such as these create a puzzle when conjoined with the assumptions (a) that attitude reports report a binary relation between an individual and some object of that individual's attitude and (b) that that object of the attitude is determined by the content of the complement sentence in the attitude report. If all of the terms in two complement sentences (e.g., "Superman can fly" and "Clark Kent can fly") have the same semantic content, then, prima facie, they ought to generate the same object of believe and, a fortiori, materially equivalent attitude reports. Frege, famously, attempts to defuse the puzzle by positing a semantic value of sense in addition to that of reference, and thereby distinguishing the semantic contents of the two complement sentences. (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.

 (e.g., Quine ), the main symptom of the unintelligibility of de re modal language is said to be the failure of coreferential “singular terms” to interchange salva veritate within the scope of modal operators. From this it is supposed to follow..

This is an essay for undergraduates. I present the basic problems of reference for descriptions and names.

For years philosophers argued for the existence of distinct yet materially coincident things by appealing to modal and temporal properties. For instance, the statue was made on Monday and could not survive being flattened; the lump of clay was made months before and can survive flattening. Such arguments have been thoroughly examined. Kit Fine has proposed a new set of arguments using the same template. I offer a critical evaluation of what I take to be his central lines of reasoning.

Millianism is reasonable; that is, it is reasonable to think that all there is to the semantic value of a proper name is its referent. But Millianism appears to be undermined by the falsehood of Substitutivity, the principle that interchanging coreferential proper names in an intentional context cannot change the truth value of the resulting belief report. Mary might be perfectly rational in assenting to ‘Twain was a great writer’ as well as ‘Clemens was not a great writer’. Her confusion (...) does not seem to preclude her from assenting to those sentences in a normal, understanding manner. That is, Assent-for-Mary is true: Mary can knowingly assent to ‘Twain was a great writer’ and ‘Clemens was not a great writer’. By Disquotation—the rough principle that if in ordinary circumstances one assents to “P”, then one believes that P—Mary believes that Twain was a great writer and she believes that it’s not the case that Clemens was a great writer. If Substitutivity were true, then since ‘Mary believes that Twain was a great writer’ is true, ‘Mary believes that Clemens was a great writer’ would have to be true too. But then Mary would amount to a refutation of the plausible principle Consistency that, roughly put, no rational adult can have occurrently held and reflectively considered and compared contradictory beliefs. Since Disquotation, Assent-for-Mary, and Consistency are true, Substitutivity has to go. (shrink)

My hunch has always been that in the end, Fregeanism will defeat Millianism. So I suspect that my (1998) arguments on behalf of Millianism are flawed. Peter Graham (1999) is confident he has found the flaws, but he has not. I hope that some clarification will encourage others to reveal the errors.

Saul Kripke's puzzle about belief demonstrates the lack of soundness of the traditional argument for the Fregean fundamental principle that the sentences 'S believes that a is F' and 'S believes that b is F' can differ in truth value even if a = b. This principle is a crucial premise in the traditional Fregean argument for the existence of semantically relevant senses, individuative elements of beliefs that are sensitive to our varying conceptions of what the beliefs are about. Joseph (...) Owens has offered a new argument for this fundamental principle, one that is not subject to Kripke's criticisms. I argue that even though Owens' argument avoids Kripke's criticisms, it has other flaws. (shrink)

In this article I offer a three-pronged defense of Millian theories, all of which share the rough idea that all there is to a proper name is its referent, so it has no additional sense. I first give what I believe to be the first correct analysis of Kripke’s puzzle and its anti-Fregean lessons. The main lesson is that the Fregean’s arguments against Millianism and for the existence of semantically relevant senses (that is, individuative elements of propositions or belief contents (...) that are sensitive to our varying personal conceptions of the referents of those elements) are viciously circular. Thus, the Fregean must give new arguments for her central claims. Second, I offer an original, positive argument for the Millian idea that the thoughts that Cicero was bald and that Tully was bald are identical. Incredibly, the argument appeals to nothing but highly intuitive, pre-theoretical principles regarding folk psychological usage—traditionally the source of Fregean intuitions. Third, I examine one of the most important recent papers on Kripke’s puzzle, that by David Sosa (1996). Sosa claims to have found a way to turn the tables on Kripke’s puzzle by using it to argue against Millian theories. I argue that Sosa’s argument on behalf of the Fregean is question-begging. I conclude that Millian theories can be seriously defended without any use of theoretical constructs such as guises or Russellian propositions, and Fregeans need to start over arguing for their theory’s central claims.

What are contents? The answer provided by the possible worlds approach is that contents are sets of possible worlds. This approach incurs serious problems and to solve them Jago suggests, in The Impossible, to get rid of the ‘possible’ bit and allowing some impossible worlds to be part of the game. In this note, I briefly consider the metaphysics behind Jago’s account and then focus on whether Jago is right in thinking that his worlds and his worlds only can do (...) the explanatory work he posits them for.

Referentialism is the view that all there is to the meaning of a singular term is its referent. Referentialism entails Substitutivity, i.e., that co-referring terms are intersubstitutable salva veritate . Frege's Paradox shows that Referentialism is inconsistent given two principles: Disquotation says that if S assents to 'P', then S believes that P, and Consistency says that if S believes that P and that not-P, then S is not fully rational. Kripke's strategy was to save Substitutivity by showing that those (...) intuitively plausible principles already led to paradox. I argue that this generalising strategy fails. The Descriptivist, who thinks that a singular term has descriptive meaning, will reject Substitutivity in Frege's Paradox, and deny that Consistency finds application in Kripke's Paradox. The Referentialist, however, may reject Consistency: if the logical properties of the contents of S's beliefs are not reflectively accessible, then S can hold contradictory beliefs without being irrational. Even if successful against Frege's and Kripke's Paradox, this response is ineffective against a strengthened version of the former which rests on Disquotation and Substitutivity, and a strengthened version of the latter which rests only on Disquotation.

In this paper, we outline an approach to giving extensional truth-theoretic semantics for what have traditionally been seen as opaque sentential contexts. We outline an approach to providing a compositional truth-theoretic semantics for opaque contexts which does not require quantifying over intensional entities of any kind, and meets standard objections to such accounts. The account we present aims to meet the following desiderata on a semantic theory T for opaque contexts: (D1) T can be formulated in a first-order extensional language; (...) (D2) T does not require quantification over intensional entities­i.e., meanings, propositions, properties, relations, or the like­in its treatment of opaque contexts; (D3) T captures the entailment relations that hold in virtue of form between sentences in the language for which it is a theory; (D4) T has a finite number of axioms. If the approach outlined here is correct, it resolves a longstanding complex of problems in metaphysics, the philosophy of mind and the philosophy of language. (shrink)

The following Principle of Substitutivity holds for the former, but not for the latter sentence: (PS) The truth value of (the proposition expressed by) a sentence that contains an occurrence of t1 remains constant when t2 is substituted for t1, provided that t1 and t2 are codesignative singular terms. It is an undeniable fact that different sentences behave differently when it comes to which substitutions preserve their truth value. What is curious is that this fact has been presented by the (...) philosophical tradition as a puzzle. To be more precise, what is supposed to be puzzling is the breakdown of PS in some sentences. Meanwhile, it is assumed that everything is as it should be, that nothing needs to be explained when we observe that the substitution of 'the number of planets' for 'nine' in 'nine is greater than seven' guarantees the preservation of truth value, in spite of the fact that the subject matter of the former sentence and the subject matter of 'the number of planets is greater than seven' are radically different. The former sentence expresses a claim about numbers and their relationships, whereas the latter sentence makes an assertion about our solar system. (shrink)

This dissertation examines critically the assumptions of extensionalism and the traditional doctrine of substitutivity, according to which codesignativeness or coextensionality of terms should be a sufficient condition to guarantee intersubstitution of expression salva veritate. First, the discussion focuses on the traditional justifications of the extensionalist principles of substitutivity. The following alleged sources of support for extensionalism are examined: the claim that the extensionalist approach to substitutivity relies on fundamental principles outside the domain of semantics, like the Law of Indiscernibility of (...) Identicals and Leibniz's Law of Substitutivity; the assumption that all sentences that exhibit failures of substitutivity have in common a certain structure, that they include explicit or implicit intensional operators, which cause failures of substitutivity; the presumption that the extensionalist principles of substitutivity follow from a thesis of compositionality of meaning,according to which the meaning of a complex expression is determined by the meanings of its components and the mode of composition. Second, the intuitive foundations of a theory about the contributions of terms to the assertions expressed by uses of sentences are explored. I claim that this theory provides strong reasons to reject the extensionalist approach to substitutivity. (shrink)

There is a certain popular argument, deriving from Ruth Barcan and Saul Kripke, from the conjunction of the Principle of the Indiscernibility of Identicals (PInI, for short) and the Principle of the Necessity of Self-Identity to the Thesis of the Necessity of Identity. My purpose is to show that this argument does not work, not at least in the form it is often presented. I also give a correct formulation of the argument and point out that PInI is not even (...) needed in the argument for the necessity of identity. (shrink)

There is a certain argument against the principle of the indiscernibility of identicals, or the thesis that whatever is true of a thing is true of anything identical with that thing. In this argument, PInI is used together with the self-evident principle of the necessity of self-identity to reach the conclusion Open image in new window, which is held to be paradoxical and, thus, fatal to PInI. My purpose is to show that the argument in question does not have this (...) consequence. Further, I argue that PInI is a universally valid principle which can be used to prove the necessity of identity. (shrink)

It is shown that the coherence of de re belief ascriptions is doubtful in view of certain plausible principles. Subsequently, it is argued, the standard argument against substitutivity in de dicto ascriptions loses some of its power. Also, some possible reactions to these results are considered.

In his famous 1979 article 'A Puzzle About Belief' Saul Kripke presents two puzzles regarding belief attribution, and he uses them to cast doubt on classical substitution arguments against the Millian view that a proper name has a 'denotation' (or reference) but no 'connotation' (or sense). In this article, I present Kripke's puzzles in what I take to be their most revealing form, discuss their relevance to the abovementioned arguments, briefly survey the ways in which philosophers have responded to these (...) puzzles, and call attention to some issues related to the puzzles that have yet to receive the consideration they deserve. (shrink)

I trace the principles known as the indiscernibility of identicals, "Leibniz's Law", and the principle of substitutivity, beginning with Aristotle, through Leibniz, Frege, and Russell, and culminating in Quine. I argue that the indiscernibility of identicals is an ontological principle and the principle of substitutivity is a linguistic principle. I discuss the relations and conflations of the principles and various attempts to defend the principle of substitutivity from apparent counter-examples, focussing on Quine's attempt to use the principle as a criterion (...) for referential and non-referential occurrences of singular terms. I find Quine's acount ambivalent and counter-intuitive, yet I think his insight that pronouns or variables are paradigmatic of reference is significant. With that as a cue, I suggest an analysis of all singular terms into a counting device and an identifying component. I argue, finally, that the principle of substitutivity holds fundamentally for the counting element, and only "by courtesy" for unanalyzed singular terms. (shrink)

Propositional attitude ascribing sentences seem to give rise to failures of substitution. Is this phenomena best accounted for semantically, by constructing a semantics for propositional attitude ascribing sentences that invalidates the Substitution Principle, or pragmatically? In this paper I argue against semantic accounts of such phenomena. I argue that any semantic theory that respects all our apparent substitution failure intuitions will entail that the noun-phrase position outside the scope of the attitude verb is not open to substitution salva veritate, which (...) is counter-intuitive. (shrink)

Speakers often judge the sentence “Lois Lane believes that Superman flies” to be true and the sentence “Lois Lane believes that Clark Kent flies” to be false. If Millianism is true, however, these sentences express the very same proposition and must therefore have same truth value. “Pragmatic” Millians like Salmon and Soames have tried to explain speakers’ “anti-substitution intuitions” by claiming that the two sentences are routinely used to pragmatically convey different propositions which do have different truth values. “Non-Pragmatic” Millians (...) like Braun, on the other hand, have argued that the Millian should not appeal to pragmatics and opt instead for a purely psychological explanation. I will present two objections against Non-Pragmatic Millianism. The first one is that the view cannot account for the intuitions of speakers who accept the identity sentence “Superman is Clark Kent”: applying a psychological account in this case, I will argue, would yield wrong predictions about speakers who resist substitution with simple sentences. I will then consider a possible response from the non-pragmatic Millian and show that the response would in fact require an appeal to pragmatics. My conclusion will be that Braun’s psychological explanation of anti-substitution intuitions is untenable, and that the Millian is therefore forced to adopt a pragmatic account. My second objection is that Non-Pragmatic Millianism cannot account for the role that certain commonsense intentional generalizations play in the explanation of behavior. I will consider a reply offered by Braun and argue that it still leaves out a large class of important generalizations. My conclusion will be that Braun’s non-pragmatic strategy fails, and that the Millian will again be forced to adopt a pragmatic account of intentional generalizations if he wants to respond to the objection. In light of my two objections, my general conclusion will be that non-pragmatic versions of Millianism should be rejected. This has an important consequence: if Millianism is true, then some pragmatic Millian account must be correct. It follows that, if standard objections against pragmatic accounts succeed, then Millianism must be rejected altogether. (shrink)

In this essay, I propose an analysis of Quine’s example ’Giorgione was so-called because of his size’, grounded on the idea of an obstinate demonstrative. In the first sections, I discuss the advantages and drawbacks of the demonstrative and logophoric treatments of ‘so called’, I highlight certain parallelisms with Davidson’s paratactic view of quotation, and I introduce independent considerations in favor of the idea of an obstinate demonstrative. In the second half of my essay, I apply this notion to Quine’s (...) example, and I discuss its consequences with respect to the principle of substitutivity of coreferential singular terms. (shrink)

In this paper I discuss two influential analyzes of belief reports, John Perry's and Marc Crimmins's "Contextual View," and Scott Soames's and Nathan Salmon's "Radical View". It is often alleged that the "Contextual View," unlike the "Radical View," is able to account for the apparent invalidity of arguments involving the substitution of coreferential names. I counter that the "Contextual View" and the "Radical View" are on a par with the respect to our intuitions regarding failures of substitutivity.

Contrary to appearances, semantic innocence can be claimed for a Fregean account of the semantics of expressions in indirect discourse. Given externalism about meaning, an expression that refers to its ordinary sense in an opaque context refers, ultimately, to its "references"; for, on this view, the reference of an expression directly determines its meaning. Externalism seems to have similar consequences for the truth-conditions of analytic sentences. If reference determines meaning, how can we distinguish a class of sentences as true in (...) virtue of meaning alone? The paper closes by hinting at an account of analyticity from an externalist perspective. (shrink)

The paper argues that philosophers commonly misidentify the substitutivity principle involved in Russell’s puzzle about substitutivity in “On Denoting”. This matters because when that principle is properly identified the puzzle becomes considerably sharper and more interesting than it is often taken to be. This article describes both the puzzle itself and Russell's solution to it, which involves resources beyond the theory of descriptions. It then explores the epistemological and metaphysical consequences of that solution. One such consequence, it argues, is that (...) Russell must abandon his commitment to propositions. (shrink)

Among the entities that can be mentally or linguistically represented are mental and linguistic representations themselves. That is, we can think and talk about speech and thought. This phenomenon is known as metarepresentation. An example is "Authors believe that people read books." -/- In this book François Recanati discusses the structure of metarepresentation from a variety of perspectives. According to him, metarepresentations have a dual structure: their content includes the content of the object-representation (people reading books) as well as the (...) "meta" part (the authors' belief). Rejecting the view that the object representation is mentioned rather than used, Recanati claims that since metarepresentations carry the content of the object representation, they must be about whatever the object representation is about. Metarepresentations are fundamentally transparent because they work by simulating the representation they are about. -/- Topics covered in this wide-ranging work include the analysis of belief reports and talk about fiction, world shifting, opacity and substitutivity, quotation, the relation between direct and indirect discourse, context shifting, semantic pretense, and deference in language and thought.

This paper addresses a certain objection to the quantificational theory of definite descriptions. According to this objection, the quantificational account cannot provide correct interpretations of definite descriptions embedded in the non-doxastic attitude ascriptions and therefore ought to be rejected. In brief, the objection says that the quantificational theory is committed to the view that a sentence of the form “The F is G” is equivalent to the claim that there is a unique F and it is G, while the ascription (...) such as, e.g., “S wants the F to be G” is not equivalent to the statement that S wants there to be a F and for it to be G. I argue that this objection is invalid as it rests on a false assumption concerning the substitutivity of the relative clauses in the non-doxastic attitude ascriptions. (shrink)
