What requirements must deflationary formal theories of truth satisfy? This chapter argues against the widely accepted view that compositional and Tarskian theories of truth are substantial or otherwise unacceptable to deflationists. First, two purposes that a formal truth theory can serve are distinguished: one descriptive, the other logical (i.e., to characterise the correctness of inferences involving ‘true’). The chapter argues that the most compelling arguments for the incompatibility of compositional and Tarskian theories concern descriptive theories only. -/- Second, two requirements (...) that any deflationist truth theory intended to serve a logical purpose must satisfy are put forward. These requirements, it is argued, suggest that (i) many well-known compositional and Tarskian theories are acceptable from a deflationist standpoint (including CT); (ii) certain other popular theories of truth (including KF and FS) are not similarly acceptable; (iii) there are no conclusive reasons to impose a conservativeness requirement on deflationary theories of truth. (shrink)

We discuss two desirable properties of deflationary truth theories: conservativeness and maximality. Joining them together, we obtain a notion of a maximal conservative truth theory - a theory which is conservative over its base, but can't be enlarged any further without losing its conservative character. There are indeed such theories; we show however that none of them is axiomatizable, and moreover, that there will be in fact continuum many theories of this sort. It turns out in effect that the deflationist (...) still needs some additional principles, which would permit him to construct his preferred theory of truth. (shrink)

Ascriptions of truth give rise to an explanatory asymmetry. For instance, we accept ‘ is true because Rex is barking’ but reject ‘Rex is barking because is true’. Benjamin Schnieder and other philosophers have recently proposed a fresh explanation of this asymmetry : they have suggested that the asymmetry has a conceptual rather than a metaphysical source. The main business of this paper is to assess this proposal, both on its own terms and as an option for deflationists. I offer (...) a pair of objections to the proposal and defend them from counter-objections. To conclude, I discuss how else to explain the asymmetry, and set out the implications for deflationism and correspondence theories of truth. (shrink)

A line of argument, presented by David Lewis, to show that the correspondence theory of truth is not a real alternative to deflationism is developed. It is shown that truthmakers, construed as concrete events or states of affairs, are unsatisfactory entities, since we do not know how to individuate them or how to identify their essential qualities. Furthermore, the real work is usually done by supervenience relations, which have little to do with truth. It is argued that the Equivalence (...) Schema is quite sufficient to yield a unitary property of being true, and that this generates a weak, but non-trivial, version of the correspondence theory of truth. (shrink)

Deflationism is usually thought to differ from the correspondence theory over whether truth is a substantial property. However, I argue that this notion of a ‘substantial property’ is tendentious. I further argue that the Equivalence Schema alone is sufficient to lead to idealism when combined with a pragmatist theory of truth. Deflationism thus has more powerful metaphysical implications than is generally thought and itself amounts to a kind of correspondence theory.

I argue that deflationism about truth does not imply minimalism about truthaptness. The condition for truth-aptness can be strengthened and the disquotationalschema restricted without resorting to any inflationary conception of truth-theoretic notions.

Philosophical work on truth covers two streams of inquiry, one concerning the nature (if any) of truth, the other concerning truth-related paradox, especially the Liar. For the most part these streams have proceeded fairly independently of each other. In his "Deflationary Truth and the Liar" (JPL 28:455-488, 1999) Keith Simmons argues that the two streams bear on one another in an important way; specifically, the Liar poses a greater problem for deflationary conceptions of truth than it does for inflationist conceptions. (...) We agree with Simmons on this point; however, we disagree with his main conclusion. In a nutshell, Simmons' main conclusion is that deflationists can solve the Liar only by compromising deflationism. If Simmons is right, then deflationists cannot solve the Liar paradox. In this paper we argue that, pace Simmons, there is an approach to the Liar that is available to deflationists, namely dialetheism. (shrink)

Deflationists about truth typically deny that truth is a causal-explanatory property. However, the now familiar 'success argument' attempts to show that truth plays an important causal-explanatory role in explanations of practical success. Deflationists have standardly responded that the truth predicate appears in such explanations merely as a logical device, and that therefore truth has not been shown to play a causal-explanatory role. I argue that if we accept Jackson and Pettit's account of causal explanations, the standard deflationist response is inconsistent, (...) for on this account even logical properties can be causally explanatory. Therefore the deflationist should remain neutral as to whether truth is a causal-explanatory property, and focus instead on the claim that truth, if it is a property, is a merely logical one. (shrink)

Deflationists claim that the truth predicate was introduced into our language merely to full a certain logico-linguistic function. Oddly enough, the question what this function exactly consists in has received little attention. We argue that the best way of understanding the function of the truth predicate is as enabling us to mimic higher-order quantification in a first-order framework. Indeed, one can show that the full simple theory of types is reducible to disquotational principles of truth. Our analysis has important consequences (...) for our understanding of truth. In this paper, we can only touch on one of them: we will argue that the insubstantiality of truth does not imply a conservativity requirement on our best theories of truth. (shrink)

Any (1-)consistent and sufficiently strong system of first-order formal arithmetic fails to decide some independent Gödel sentence. We examine consistent first-order extensions of such systems. Our purpose is to discover what is minimally required by way of such extension in order to be able to prove the Gödel sentence in a nontrivial fashion. The extended methods of formal proof must capture the essentials of the so-called 'semantical argument' for the truth of the Gödel sentence. We are concerned to show that (...) the deflationist has at his disposal such extended methods--methods which make no use or mention of a truth-predicate. (edited). (shrink)

Field (2000) claims that both inflationists and deflationists can and should accept the existence of linguistic indeterminacy in their own language. This paper shows that inflationists and deflationists consider the nature of indeterminacy quite differently; in particular, deflationists’ notion of indeterminacy lacks the kind of objectivity inflationists’ notion has; as a result, while both inflationists and deflationists can and should accept the existence of manifest indeterminacy such as vagueness, only inflationists can accept the existence of hidden indeterminacy such as the (...) yet–to–be–discovered indeterminacy thought to be involved in terms of our current scientific theories. The paper also considers the question how well deflationists can do without hidden indeterminacy. (shrink)

This paper is about the relationship between truthmaking—one of the pillars of contemporary metaphysics—and deflationism about truth—one of the main contenders in the debate about truth, and a key component of the broad anti-metaphysical philosophical approach known as pragmatism. Many philosophers have argued that deflationism and truthmaking are incompatible or in conflict in some interesting way. Some take this to count against deflationism, others to count against truthmaking. In this paper I argue that deflationism and truthmaking (...) are compatible in most of the ways in which they are commonly thought to be incompatible. Deflationism does not render truthmaking unintelligible, avoidable, unmotivated, or trivial. While deflationism is incompatible with certain ideas within mainstream truthmaking, I argue that these ideas result from merely optional assumptions and principles commonly accepted by mainstream truthmaker theorists. (shrink)

I here defend a theory consisting of four claims about ‘property’ and properties, and argue that they form a coherent whole that can solve various serious problems. The claims are (1): ‘property’ is defined by the principles (PR): ‘F-ness/Being F/etc. is a property of x iff x is F’ and (PA): ‘F-ness/Being F/etc. is a property’; (2) the function of ‘property’ is to increase the expressive power of English, roughly by mimicking quantification into predicate position; (3) property talk should be (...) understood at face value: apparent commitments are real and our apparently literal use of ‘property’ is really literal; (4) there are no properties. In virtue of (1)–(2), this is a deflationist theory and in virtue of (3)–(4), it is an error theory. (1) is fleshed out as a claim about understanding conditions, and it is argued at length, and by going through a number of examples, that it satisfies a crucial constraint on meaning claims: all acceptance facts about ‘property’ can be explained, together with auxiliary facts, on its basis. Once claim (1) has been expanded upon, I argue that the combination of (1)–(3) provides the means for handling several problems: they help giving a happy-face solution to what I call the paradox of abstraction , they form part of a plausible account of the correctness of committive sentences, and, most importantly, they help respond to various indispensability arguments against nominalism. (shrink)

Deflationists about truth hold that the function of the truth predicate is to enable us to make certain assertions we could not otherwise make. Pragmatists claim that the utility of negation lies in its role in registering incompatibility. The pragmatist insight about negation has been successfully incorporated into bilateral theories of content, which take the meaning of negation to be inferentially explained in terms of the speech act of rejection. We implement the deflationist insight in a bilateral theory by taking (...) the meaning of the truth predicate to be explained by its inferential relation to assertion. We combine this account of the meaning of the truth predicate with a new diagnosis of the Liar Paradox: its derivation requires the truth rules to preserve evidence, but these rules only preserve commitment. The result is a novel inferential deflationist theory of truth, which solves the Liar Paradox in a principled manner. We end by showing that our theory and simple extensions thereof have the resources to axiomatize the internal logic of several supervaluational hierarchies, including Cantini’s. This solves open problems of Halbach (2011) and Horsten (2011). (shrink)

I defend the deflationary theory of truth and reference I have proposed from the objections raised in Vann McGee’s “Thought, Thoughts, and Deflationism,” trying where possible to use arguments that other deflationists might find useful.

Logical consequence is typically construed as a metalinguistic relation between sentences. Deflationism is an account of logic that challenges this orthodoxy. In Williamson’s recent presentation of deflationism, logic’s primary concern is with universal generalizations over absolutely everything. As well as an interesting account of logic in its own right, deflationism has also been recruited to decide between competing logics in resolving semantic paradoxes. This paper defends deflationism from its most important challenge to date, due to Ole (...) Hjortland. It then presents two new problems for the view. Hjortland’s objection is that deflationism cannot discriminate between distinct logics. I show that his example of classical logic and supervaluationism depends on equivocating about whether the language includes a “definitely” operator. Moreover, I prove a result that blocks this line of objection no matter the choice of logics. I end by criticizing deflationism on two fronts. First, it cannot do the work it has been recruited to perform. That is, it cannot help adjudicate between competing logics. This is because a theory of logic cannot be as easily separated from a theory of truth as its proponents claim. Second, deflationism currently has no adequate answer to the following challenge: what does a sentence’s universal generalization have to do with its logical truth? I argue that the most promising, stipulative response on behalf of the deflationist amounts to an unwarranted change of subject. (shrink)

(2000). DEFLATIONISM AND THE DISQUOTATIONAL SCHEMA: LETTING THE AIR OUT OF WRIGHT'S ARGUMENT AGAINST MINIMAL TRUTH. Philosophical Papers: Vol. 29, No. 1, pp. 43-59.

This chapter contains sections titled: 3.1 3.2 3.3 3.4 3.5.

The paper presents an interpretation of Brandom¿s analysis of de re specifying attitude-ascriptions. According to this interpretation, his analysis amounts to a deflationist conception of intentionality. In the first section I sketch the specific role deflationist theories of truth play within the philosophical debate on truth. Then I describe some analogies between the contemporary constellation of competing truth theories and the current confrontation of controversial theories of intentionality. The second section gives a short summary of Brandom¿s analysis of attitude-ascription, focusing (...) on his account of the grammar of de re ascriptions of belief. The third section discusses in detail those aspects of his account from which a deflationist conception of intentionality may be derived, or which at least permit such a conception. In the proposed interpretation of Brandom¿s analysis, the vocabulary expressing the representational directedness of thought and talk does not describe a genuine property of mental states, but has an alternative descriptive function and in addition contains a performative and a meta­descriptive element. (shrink)

The paper discusses what kind of truth bearer, or truth-ascription, a deflationist should take as primary. I first present number of arguments against a sententialist view. I then present a deflationary theory which takes propositions as primary, and try to show that it deals neatly with a wide range of linguistic data. Next, I consider both the view that there is no primary truth bearer, and the most common account of sentence truth given by deflationists who take propositions as primary, (...) and argue that they both attribute an implausible type of ambiguity to “true”. This can be avoided, however, if truth-ascriptions to sentences are taken as a certain form of pragmatic ellipses. I end by showing how this hypothesis accommodates a number of intuitions involving truth-ascriptions to sentences. (shrink)

I here develop a specific version of the deflationary theory of truth. I adopt a terminology on which deflationism holds that an exhaustive account of truth is given by the equivalence between truth-ascriptions and de-nominalised (or disquoted) sentences. An adequate truth-theory, it is argued, must be finite, non-circular, and give a unified account of all occurrences of “true”. I also argue that it must descriptively capture the ordinary meaning of “true”, which is plausibly taken to be unambiguous. Ch. 2 (...) is a critical historical survey of deflationary theories, where notably disquotationalism is found untenable as a descriptive theory of “true”. In Ch. 3, I aim to show that deflationism cannot be finitely and non-circularly formulated by using “true”, and so must only mention it. Hence, it must be a theory specifically about the word “true” (and its foreign counterparts). To capture the ordinary notion, the theory must thus be an empirical, use-theoretic, semantic account of “true”. The task of explaining facts about truth now becomes that of showing that various sentences containing “true” are (unconditionally) assertible. In Ch. 4, I defend the claim (D) that every sentence of the form “That p is true” and the corresponding “p” are intersubstitutable (in a use-theoretic sense), and show how this claim provides a unified and simple account of a wide variety of occurrences of “true”. Disquotationalism then only has the advantage of avoiding propositions. But in Ch. 5, I note that (D) is not committed to propositions. Use-theoretic semantics is then argued to serve nominalism better than truth-theoretic ditto. In particular, it can avoid propositions while sustaining a natural syntactic treatment of “that”-clauses as singular terms and of “Everything he says is true”, as any other quantification. Finally, Horwich’s problem of deriving universal truth-claims is given a solution by recourse to an assertibilist semantics of the universal quantifier. (shrink)

How can we distinguish between quasi-realist expressivism and normative realism? The most promising answer to this question is the “explanation” explanation proposed by Dreier (2004), Simpson (2018), and others: the two views might agree in their claims about truth and objectivity, or even in their attributions of semantic content to normative sentences, but they disagree about how to explain normative meaning. Realists explain meaning by invoking normative facts and properties, or representational relations between normative language and the world, the thought (...) goes, while expressivists appeal instead to desire-like mental states in their explanations of meaning. However, I argue that, if we adopt a deflationary approach to representation and other related notions, there need be no such explanatory divide between expressivism and anything recognizable as a plausible notion of normative realism. Any alleged explanatory criterion for realism will either be incompatible with deflationism, or it will fail to capture some standard versions of normative realism. I conclude that, in a deflationary framework, expressivism is compatible with genuine realism. (shrink)

The paper aims at providing an argument for a deflationary treatment of the notion of public language meaning. The argument is based on the notion of standards of correctness; I will try to show that as correctness assessments are context-involving, the notion of public language meaning cannot be treated as an explanatory one. An elaboration of the argument, using the notion of ground is provided. Finally, I will consider some limitations of the reasoning presented.

The aim of this paper is to show that the interpretivist account of propositional attitudes fails even at the most plausible reading that treats this theory as a version of the deflationary approach to existence coupled with a metaphysical claim about the judgement-dependence of propositional attitudes. It will be argued that adopting a deflationary reading of interpretivism allows this theory to avoid the common charge of fictionalism, according to which interpretivists cannot maintain realism about attitudes as their theory becomes a (...) covert form of mental fictionalism. However, as will be shown, the deflationary version of interpretivism faces a fatal dilemma: either it becomes indistinguishable from generic deflationism about the mental, or it must embrace the metaphysical thesis of judgement-dependence of propositional attitudes. The latter option leads to unacceptable epistemological consequences, as it cannot accommodate intuitions about possibility of error in attribution of attitudes. Thus, it turns out that even a subtle version of interpretivism is not a viable theory of intentional states. (shrink)

It is widely held that truth and reference play an indispensable explanatory role in theories of meaning. By contrast, so-called deflationists argue that the functions of these concepts are merely expressive and never explanatory. Robert Brandom has proposed both a variety of deflationism — the anaphoric theory —, and a theory of meaning — inferentialism — which doesn’t rely on truth or reference. He argues that the anaphoric theory counts against his (chiefly referentialist) rivals in the debate on meaning (...) and thereby paves the way for inferentialism. In this paper, I give a friendly reconstruction of anaphoric deflationism (section II) and point to a distinguishing feature of the theory with respect to other deflationist proposals. While Brandom simply assumes, but doesn’t earn this feature, I propose a natural argument to justify it (section III). Then, however, I point out a subtle but clear sense in which truth and reference can play a role in explaining meaning, even if the anaphoric theory holds. Thus, anaphoric deflationism will turn out to be neutral in the debate on meaning (section IV). (shrink)

Any consistent and sufficiently strong system of first-order formal arithmetic fails to decide some independent Gödel sentence. We examine consistent first-order extensions of such systems. Our purpose is to discover what is minimally required by way of such extension in order to be able to prove the Gödel sentence in a non-trivial fashion. The extended methods of formal proof must capture the essentials of the so-called 'semantical argument' for the truth of the Gödel sentence. We are concerned to show that (...) the deflationist has at his disposal such extended methods-methods which make no use or mention of a truth-predicate. This consideration leads us to reassess arguments recently advanced-one by Shapiro and another by Ketland-against the deflationist's account of truth. Their main point of agreement is this: they both adduce the Gödel phenomena as motivating a 'thick' notion of truth, rather than the deflationist's 'thin' notion. But the so-called 'semantical argument', which appears to involve a 'thick' notion of truth, does not really have to be semantical at all. It is, rather, a reflective argument. And the reflections upon a system that are contained therein are deflationarily licit, expressible without explicit use or mention of a truth-predicate. Thus it would appear that this anti-deflationist objection fails to establish that there has to be more to truth than mere conformity to the disquotational T-schema. (shrink)

Inference rule deflationism is the thesis that the nature of truth can be explained in terms of the inference rules governing the word "true". This paper argues, first, that, in light of the semantic paradoxes, the inference rule deflationist must reject some of the classical rules of inference. It is argued, secondly, that inference rule deflationism is incompatible with model theoretic approaches to the definition of logical validity. Here the argument focuses on the question whether the number of (...) primitive referring expressions in a natural language is denumerably infinite. Finally, it is argued that these conclusions pertain to T-schema deflationism and Horwich's minimal theory as well. (shrink)

Deflationists cannot make sense ofthe notion of referential indeterminacybecause they deny the existence of substantivereference. One way for them to make sense ofthe objective existence of linguisticindeterminacy is by embracing theworldly (or objectual) view ofindeterminacy, the view that indeterminacyexists not in reference relations but in the(non-linguistic) world itself. On this view,the entire world is divided into precisified worlds, just as it is dividedinto temporal slices and (arguably) alethicpossible worlds. Supervaluationism proves tobe neutral with respect to the debate betweenthe worldly view (...) and the referential view ofindeterminacy. (shrink)

I clarify how the requirement of conservative extension features in the thinking of various deflationists, and how this relates to another litmus claim, that the truth-predicate stands for a real, substantial property. I discuss how the deflationist can accommodate the result, to which Cieslinski draws attention, that non-conservativeness attends even the generalization that all logical theorems in the language of arithmetic are true. Finally I provide a four-fold categorization of various forms of deflationism, by reference to the two claims (...) of conservativeness and substantiality. This helps to clarify the various possible positions in the deflationism debate. (shrink)

Deflationists about truth generally regard the contribution that ‘true’ makes to utterances to be purely logical or expressive: it exists to facilitate communication, and remedy our expressive deficiencies that are due to ignorance or finitude. This paper presents a challenge to that view by considering alethic desires. Alethic desires are desires for one’s beliefs to be true. Such desires, I argue, do not admit of any deflationarily acceptable analysis, and so challenge the deflationist’s austere view about the semantic role of (...) ‘true’. I consider a number of deflationist proposals for analyzing alethic desires, and find them all problematic. (shrink)

I here argue for a particular formulation of truth-deflationism, namely, the propositionally quantified formula, (Q) “For all p, <p> is true iff p”. The main argument consists of an enumeration of the other (five) possible formulations and criticisms thereof. Notably, Horwich’s Minimal Theory is found objectionable in that it cannot be accepted by finite beings. Other formulations err in not providing non-questionbegging, sufficiently direct derivations of the T-schema instances. I end by defending (Q) against various objections. In particular, I (...) argue that certain circularity charges rest on mistaken assumptions about logic that lead to Carroll’s regress. I show how the propositional quantifier can be seen as on a par with first-order quantifiers and so equally acceptable to use. While the proposed parallelism between these quantifiers is controversial in general, deflationists have special reasons to affirm it. I further argue that the main three types of approach the truth-paradoxes are open to an adherent of (Q), and that the derivation of general facts about truth can be explained on its basis. (shrink)

It is often assumed that deflationist accounts of truth are a product of philosophy of logic and language in the twentieth century. In this paper I show why this assumption is historically short-sighted. An early version of deflationism about truth can already be found in Brentano’s 1889 lecture “On the Concept of Truth.” That Brentano is a precursor of deflationism has gone largely unnoticed because of a different reception of his lecture: according to most scholars, Brentano proposes in (...) it a revision of the correspondence theory of truth that he later rejected in favour of an epistemic theory. Contrary to this received interpretation, I argue that Brentano actually tried to show how one can minimize an account of truth without thereby sacrificing a robust realist intuition about the objectivity of truth. Brentano held on to this deflationist view in his later years, when he assigned self-evident judgments a primary role in our understanding of truth. (shrink)

Takes up Field's version of Logicism—a position that he calls ‘deflationism’. Unlike traditional Logicists, Field does not analyse mathematical propositions into purely logical ones, but he does analyse mathematical knowledge into logical knowledge. Several objections are raised to deflationism, revolving around Field's contention that mathematics consists mostly of falsehoods. Contends that, although mathematics, literally and platonically construed, is not true, it does convey genuine information.

Deflationism about truth, what is often simply called “deflationism”, is really not so much a theory of truth in the traditional sense, as it is a different, newer sort of approach to the topic. Traditional theories of truth are part of a philosophical debate about the nature of a supposed property of truth. Philosophers offering such theories often make suggestions like the following: truth consists in correspondence to the facts; truth consists in coherence with a set of beliefs (...) or propositions; truth is what is acceptable in the ideal limit of inquiry. According to deflationists, such suggestions are mistaken, and, moreover, they all share a common mistake. The common mistake is to assume that truth has a nature of the kind that philosophers might find out about and develop theories of. The main idea of the deflationary approach is (a) that all that can be significantly said about truth is exhausted by an account of the role of the expression ‘true’ or of the concept of truth in our talk and thought, and (b) that, by contrast with what traditional views assume, this role is neither metaphysically substantive nor explanatory. For example, according to deflationary accounts, to say that ‘snow is white’ is true, or that it is true that snow is white, is in some sense strongly equivalent to saying simply that snow is white, and this, according to the deflationary approach, is all that can be said significantly about the truth of ‘snow is white’. Philosophers looking for some underlying nature of some truth property that is attributed with the use of the expression ‘true’ are bound to be frustrated, the deflationist says, because they are looking for something that isn’t there. Deflationism comprises a variety of different versions, each of which have gone by different names, including at least the following: disquotationalism, minimalism, prosententialism, the redundancy theory, the disappearance theory, the no-truth theory. There has not always been terminological consensus in the literature about how to use these labels: sometimes they have been used interchangeably; sometimes they have been used to mark distinctions between different developments of the same general approach. The actual variety of deflationary views has not always been clear in discussions of this approach, especially in the earlier literature, where important differences are occasionally missed. To help clear this up, we will use ‘deflationism’ to denote the general approach we want to discuss and reserve other names for specific versions of that approach. (shrink)

Deflationists believe that the question “What is truth?” should be answered not by means of a metaphysical inquiry into the nature of truth, but by figuring out what use we make of the concept of truth, and the word ‘true’, in practice. This article accepts this methodology, and it thereby rejects pluralism about truth that is driven by ontological considerations. However, it shows that there are practical considerations for a pluralism about truth, formulated at the level of use. The theory (...) expounded by this article states that truth is a dual-purpose tool; it can be used as a device for transferring justificatory burdens and, for select areas of discourse, it can also be used as a standard, a norm. This contrast in how truth is used introduces a bifurcation in our discourse that is reminiscent of metaphysical divides traced by more traditional versions of alethic pluralism. However, my pluralism “at the level of use” states that truth is plural solely at the level of use. It is unified at both the conceptual as well as the metaphysical level. At those levels, the theory takes its cue from deflationism. As such, this theory is offered as a midway point and as a potential way forward in the debate between deflationism and pluralism.

Every deflationist semantic theory has its inflationist correlate: this is the semantic theory the deflationist theory is designed to deflate. This chapter presents Radical Inflationism and Radical Deflationism as stipulatively defined theories, without regard to who might subscribe to them, or to one or another of their parts. Radical Deflationism is based on a view worked out over a number of important publications by Hartry Field. In other words, radical inflationist is on board with the view Hartry Field (...) had when he wrote 'Tarski's theory of truth', that our notions of reference and truth are correspondence notions that stand in need of physicalistic explications. This is that Radical Deflationism's claim that the only reason we need a notion of truth is as a device of disquotation is hostage to the theory's ability to meet what we will presently see is its greatest challenge. (shrink)

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. (shrink)

Deflationists have argued that truth is an ontologically thin property which has only an expressive function to perform, that is, it makes possible to express semantic generalizations like 'All the theorems are true', 'Everything Peter said is true', etc. Some of the deflationists have also argued that although truth is ontologically thin, it suffices in conjunctions with other facts not involving truth to explain all the facts about truth. The purpose of this paper is to show that in the case (...) of arithmetic, it is difficult to combine the expressive with the explanatory function of truth if the latter is understood in a deflationist way. We will make our point by investigating several logical systems: first-order logic, full second-order logic, and existential second-order (?11-) logic. (shrink)

Deflationism is the view that certain metaphysical debates are defective, leaving it open whether the defect is best explained in semantic, conceptual, or epistemic terms. Local semantic deflationism is the thesis that familiar metaphysical debates, which appear to be about the existence and identity of material objects, are merely verbal. It’s a form of local deflationism because it restricts itself to one particular area of metaphysics. It’s a form of semantic deflationism because the defect it purports (...) to identify in these debates is explained in terms of the broadly semantic notion of a merely verbal disputation. Three questions about this thesis are asked and answered here. Does a commitment to the principle of interpretive charity support it? No. Does it avoid the problems that plagued Carnap? No. Does it support a linguistic turn with respect to questions about the nature of material things? No. The central take-home message is that local semantic deflationism is unstable: advocates of the view must admit that debates about material coincidence and identity are substantive. (shrink)

This paper argues, in response to Huw Price, that deflationism has the resources to account for the normativity of truth. The discussion centers on a principle of hyper-objective assertibility, that one is incorrect to assert that p if not-p. If this principle doesn't state a fact about truth, it neednt be explained by deflationists. If it does,, it can be explained.

The paper starts by highlighting that virtually nobody would object to claims such as “to regard an assertion or a belief or a thought as true or false is to regard it as being right or wrong”—a claim that shows that truth is intrinsically normative. It is well known that alethic deflationists deny this. Paul Horwich, for instance, maintains that nothing shows that TRUTH is a normative concept in the way that OUGHT is. By relying on a distinction among dimensions (...) of normativity I will try to pinpoint the weakness of Horwich’s argument in the fact that he works with a strong, uncalled-for, interpretation of normativity, whereas a weaker interpretation is more than enough. However, the impression might persist that a different understanding of the normativity of truth on the part of deflationists could eventually show the compatibility between alethic deflationism and normativity. The remaining part of the paper is devoted to contend that this is a wrong impression. Accordingly, it is stated that the normativity exerted by truth is ascribable in the final analysis to the world, and the provocative claim is defended that alethic deflationism lacks the conceptual resources to account for the relation between language and the world. (shrink)

Deflationsism about truth is a pot-pourri, variously claiming that truth is redundant, or is constituted by the totality of 'T-sentences', or is a purely logical device (required solely for disquotational purposes or for re-expressing finitarily infinite conjunctions and/or disjunctions). In 1980, Hartry Field proposed what might be called a 'deflationary theory of mathematics', in which it is alleged that all uses of mathematics within science are dispensable. Field's criterion for the dispensability of mathematics turns on a property of theories, called (...) conservativeness. I present some technical results, some of which may be found in Tarski (1936), concerning the logical properties of truth theories; in particular, concerning the conservativeness of adding a truth theory for an object level language to any theory expressed in it. It transpires that various deflationary truth theories behave somewhat differently from the standard Tarskian truth theory. These results suggest that Tarskian theories of truth are not redundant or dispensable. Finally, I hint at an analogy between the behaviour of mathematical theories and of standard (Tarskian) theories of truth with respect to their indispensability to, as Quine would put, our 'scientific world-view'.

Controversy has arisen of late over the claim that deflationism about truth requires that we explain meaning in terms of something other than truth-conditions. This controversy, it is argued, is due to unclarity as to whether the basic deflationary claim that a sentence and a sentence that attributes truth to it are equivalent in meaning is intended to involve the truth- predicate of the object language for which we develop an account of meaning, or is intended to involve the (...) truth- predicate of the metalanguage in which we develop an account of meaning. The former view is compatible with the truth-conditional theory of meaning for the object language, the latter is incompatible with it. However, the former view is also trivially true; hence we should endorse the claim that any form of deflationism worth being interested in is incompatible with understanding meaning truth-conditionally.

The paper proposes a strategy for understanding metaphysical grounding in deflationary terms and, more generally, proposes a form of methodological deflationism with respect to the notions of ground. The idea is to define a deflationary is grounded in-predicate by appeal to the two-place non-causal connective ‘because’ and a deflationary truth predicate. To this end, we discuss the explanatory role of the truth-predicate in non-causal explanations and develop a theory of truth for the language of the ‘because’-connective. We argue that (...) at least from a logical perspective our deflationary notion of ground is up to the task. (shrink)

On an expressivist view, ethical claims are not fact stating; instead they serve the alternative function of expressing our feelings, attitudes and values. On a deflationary view, truth is not a property with a nature to be analyzed, but merely a grammatical device to aid us in endorsing sentences. Views on the relationship between expressivism and deflationism vary widely: they are compatible; they are incompatible; they are a natural pair; they doom one another. Here I explain some of these (...) views, extract some necessary distinctions, and put these to use for understanding expressivism. I argue that contrary to the opinions of some, deflationism doesn’t help with problems of objectivity, knowledge and reasoning in ethics. I suggest alternative expressivist treatments of these problems, and show how expressivism as a metaethical view must have consequences for our ethical lives and beliefs. In particular it must affect the way we deal with ethical consistency—when norms or beliefs conflict—and ethical incompleteness—when ethical questions have no right answer. (shrink)

This essay argues that deflationism is incompatible with the phenomenon of referential indeterminacy. This puts the deflationist in the difficult position of having to deny the possibility of what otherwise seems like a manifest and theoretically important phenomenon. Section 1 provides background on deflationism. Section 2 considers an intuitive argument by Stephen Leeds to the effect that deflationism precludes RI; the essay argues that this argument does not succeed. The rest of the essay presents its own, distinct (...) argument for the incompatibility of deflationism and RI. Section 3 argues that direct RI—RI that is not simply a derivative of some other, nonreferential instance of indeterminacy—is strictly incompatible with deflationism. Section 4 considers a couple of different ways the deflationist might try to achieve indirect RI—via indeterminate identity and indeterminate synonymy—and argues that each is unsatisfactory. (shrink)
