According to the deflationary theory of truth, to assert that a statement is true is just to assert the statement itself. For example, to say that ‘snow is white’ is true, or that it is true that snow is white, is equivalent to saying simply that snow is white, and this, according to the deflationary theory, is all that can be said significantly about the truth of ‘snow is white’.

In this paper, I address some of the chief challenges, or problems, for Deflationary Theories of Truth, viz., the Generalization Problem, the Conservativeness Argument, and the Success Argument.

I critically examine some deflationary theories of properties, according to which properties are ‘shadows of predicates’ and quantification over them serves a mere quasi-logical function. I start by considering Hofweber’s internalist theory, and pose a problem for his account of inexpressible properties. I then introduce a theory of properties that closely resembles Horwich’s minimalist theory of truth. This theory overcomes the problem of inexpressible properties, but its formulation presupposes the existence of various kinds of (...) abstract objects. I discuss some ways to reduce these existence assumptions, but ultimately suggest that deflationists can hardly avoid quantification over abstract objects of one sort or another. I conclude that property deflationism is perhaps not as deflationary as some philosophers want it to be, but that it’s still apt to call the position ‘deflationary’. (shrink)

In ‘The Status of Content,’ Paul Boghossian points out an embarrassment in which A.J. Ayer finds himself in his extensive irrealism. Ayer embraces both an emotivist theory of ethics and a deflationary theory of truth. According to an emotivist theory, sentences that look like perfectly good declarative sentences, such as ‘One ought not to kill,’ should be interpreted as non-declarative sentences. According to a deflationary theory of truth, ‘truth’ is not a (...) predicate of sentences, and sentences of the form ‘“p” is true’ are equivalent to sentences of the form ‘p.’ Boghossian argues that emotivism and deflationism turn out to be incompatible.Boghossian's criticism should not be presented before we ask this question: What motivates Ayer's subversion of surface grammar? A typical motivation to provide an analysis of a certain region of discourse is to find a way in which patterns of inference and compositionality could be more perspicuously presented. (shrink)

It has been argued that deflationary theories of truth stumble over the normativity of truth. This paper maintains that the normativity objection does not pose problems to at least one version of deflationism, minimalism. The rest of the paper discusses truth-related norms, showing that either they do not hold or they are not troublesome for deflationism.

I argue that deflationary theories of truth reveal an important lesson for the broader theory of truth: although the notion of truthmaking has played an essential role in many traditional theories of truth, it can be separated from and survive the rejection of substantive theories of truth. I argue that many of the traditional substantive theories of truth are unified in defining truth in terms of the ontological grounds that are needed to (...) account for truth. Deflationists reject the idea that a theory of truth needs such metaphysical implications, but in so doing they need not rule out the possibility of developing an independently motivated theory of truthmaking. I argue that deflationists can and should embrace truthmaker theory, once it is shorn from its connection to the traditional project of defining truth. (shrink)

Theodore de Laguna develops and argues for a deflationary view of truth well before the publication of what many have taken to be its source, or at least its inspiration, namely Frank P. Ramsey’s paper ‘Facts and Propositions’. I outline de Laguna’s view of truth and the arguments he offers for it; I also discuss its role in the history of twentieth-century philosophy. My outline and discussion serve as an introduction to de Laguna’s ‘A Nominalistic Interpretation of (...) Truth’, a paper he originally wrote in English but which has hitherto only been published in French. (shrink)

The article first rehearses three deflationary theories of reference, (1) disquotationalism, (2) propositionalism (Horwich), and (3) the anaphoric theory (Brandom), and raises a number of objections against them. It turns out that each corresponds to a closely related theory of truth, and that these are subject to analogous criticisms to a surprisingly high extent. I then present a theory of my own, according to which the schema “That S(t) is about t” and the biconditional “S (...) refers to x iff S says something about x” are exhaustive of the notions of aboutness and reference. An account of the usefulness of “about” is then given, which, I argue, is superior to that of Horwich. I close with a few considerations about how the advertised theory relates to well-known issues of reference, the conclusions of which is (1) that the issues concern reference and aboutness only insofar as the words “about” and “refer” serve to generalise over the claims that are really at issue, (2) that the theory of reference will not settle the issues, and (3) that it follows from (2) that the issues do not concern the nature of aboutness or reference.

Partly due to the influence of Tarski's work, it is commonly assumed that any good theory of truth implies biconditionals of the sort mentioned in Convention T: instances of the T-Schema "s is true in L if and only if p" where the sentence substituted for "p" is equivalent in meaning to s. I argue that we must take care to distinguish the claim that implying such instances is sufficient for adequacy in an account of truth from (...) the claim that doing so is necessary. The claim that doing so is sufficient is a common component of deflationary theories of truth, while the claim that it is necessary, though often assumed, must be denied by proponents of rival inflationary theories of truth. I discuss the clarification of the debate between these views of truth that results from distinguishing the necessity and the sufficiency claims, and examine the prospects for its resolution.

Much recent work in the philosophy of language has been concerned with the project of constructing a theory of reference and truth for natural languages. I shall discuss certain assumptions which have been tacitly in the background of most of this work; what I hope my rather sceptical discussion will show is that the project of giving a theory of reference and truth is much more problematic - and more closely tied to questions of general philosophical (...) interest - than is usually suspected. (shrink)

Prosentential theorists claim that sentences such as “That’s true” are prosentences that function analogously to their better known cousins–pronouns. For example, just as we might use the pronoun ‘he’ in place of ‘James’ to transform “James went to the supermarket” into “He went to the supermarket,” so we might use the prosentenceforming operator ‘is true’ to transform “Snow is white” into “‘Snow is white’ is true.” According to the prosentential theory of truth, whenever a referring expression (for example, (...) a definite description or a quote-name) is joined to the truth predicate, the resulting statement contains no more content than the sentence(s) picked out by the referring expression. To assert that a sentence is true is simply to assert or reassert that sentence; it is not to ascribe the property of truth to that sentence. The prosentential theory is one kind of deflationary theory of truth. Like all deflationary theories, it provides an alternative to explanations of truth that analyze truth in terms of reference, predicate satisfaction or a correspondence relation. (shrink)

Minimalism is currently the received deflationary theory of truth. On minimalism, truth is a transparent concept and a deflated property of truth bearers. In this paper, I situate minimalism within current deflationary debate about truth by contrasting it with its main alternative―the redundancy theory of truth. I also outline three of the primary challenges facing minimalism, its formulation, explanatory adequacy and stability, and draw some lessons for the soundness of its conception (...) of truth.

The primitivist theory of truth, i.e., the view that truth cannot be analysed in more fundamental terms, has been cleverly revamped by Jamin Asay, who has combined a primitivist approach to the concept of truth with a deflationary approach to the (metaphysical) property of being true. This paper aims to adjust Asay’s primitivist theory to consistently include the primitiveness of the (pre-theoretical) correspondence relation, grasped by our correspondence intuition, alongside the primitiveness of truth. (...) In the process, I apply a thesis by Rögnvaldur Ingthorsson, according to which the correspondence of beliefs to facts (broadly construed) can occur with no commitment to a correspondence theory of truth. Then I argue why Asay’s theory might not be able to account for the primitiveness of the pre-theoretical correspondence relation. Finally, I use a suggestion by André Kukla concerning the possible entailment between an ineffable insight and its effable consequences, to build a revised primitivist theory of truth. (shrink)

Even though pragmatic theories of truth are not widely held, they have advantages not found elsewhere. Here I focus on one such advantage: that a pragmatic theory of truth does not limit the range of truth-apt beliefs and thereby “block the way of inquiry.” Furthermore, I argue that this speaks for a particular formulation of the pragmatic theory of truth, one that shifts away from Peircean approaches and their emphasis on temporal independence, and toward (...) a theory that instead emphasizes truth’s subject independence.

This article, after briefly discussing Alfred Tarski's influential theory of truth, turns to a more recent theory of truth, a deflationary, or minimalist, theory. One of the chief elements of a deflationary, or minimalist, theory of truth is that it replaces the question of what truth is with the question of what “true” does. After setting out the central features of the minimalist theory of truth, the article explains (...) the motivation for opting for such a position. In addition, it provides some reasons for thinking that such a theory of truth is “minimal” or “deflationary” in the way that contemporary truth theorists have claimed it to be. (shrink)

Correspondence theories are frequently charged with being either implausible—metaphysically troubling and overly general—or trivial—collapsing into deflationism's “‘P’ is true iff P.” Philip Kitcher argues for a “modest” correspondence theory, on which reference relations are causal relations, but there is no general theory of denotation. In this article, I start by showing that, understood this way, “modest” theories are open to charges of triviality. I then offer a refinement of modesty, and take the first steps toward articulating a modest (...) correspondence theory, giving a particular account of the relation between predicates, properties, and extensions. Finally, I argue that my account does not collapse into a deflationary one. (shrink)

The article is about one of the vital problem for analytic philosophy which is how to define truth value for sentences which include their own truth predicate. The aim of the article is to determine Saul Kripke’s approach to widen epistemological truth to create a systemic model of truth. Despite a lot of work on the subject, the theme of truth is no less relevant to modern philosophy. With the help of S. Kripke’s article “Outline (...) of the Theory of Truth” and R. L. Kirkham’s work “Theories of Truth: A Critical Introduction” the author tried to represent a non-classical approach which is now known as Saul Kripke’s truth value gaps theory. Considering his solving of the Liar Paradox, as well as the Strenghened Liar, it is obvious that there could be the circumstances (or facts) that make sentences have no truth value. In that case the solving of the paradox attracts Kleene’s non-classical three-valued logic which contains the third way and the solution falls into the gap between truth and falsity. Hence there are no relevant and full satisfactory ways to solve the Liar’s Paradox by the language-levels ap- proach. The task consists in an extension of the approach to natural languages and elimination of an ad hoc element as well. Besides that, the language-levels approach refers to the speaker that means that only the last one is allowed to define the hierarchy of the levels and truth value of sentence, but often he does not know what level he is speaking of. As Kripke stated, contingent facts can lead to a paradox which isn’t allowed for a logical point of view. However usage of mathematical apparatus allows the theory in question to be universalized and moreover paves the way to futher epistemological develop- ment of the problem in question. As Kripke’s theory is formalized and presented as a functional series, it gives access to a system model of truth whose elements would be epistemological theories (concepts) of truth. Such a model, for instance, confirms the validity of the deflationary concept of truth. Refs 7. (shrink)

Although its use is not universal, there is a map of the logical space of theories of truth that is widely applied. According to this map, the most foundational divide amongst theories of truth is that between deflationary and inflationary theories, where, roughly, the former hold that truth is an insubstantial, logical property of little philosophical interest and the latter that it is a substantial property suitable for philosophical attention. Amongst the inflationary theories, there are other (...) fundamental divisions. For example, on the one hand, correspondence theorists hold that the truth of a proposition is a matter of the proposition’s standing in a relation to something else which is not a proposition, such as a fact. On the other hand, coherence theorists hold that the truth of a proposition is a matter of its relations to other propositions. And again, pragmatists hold that the truth of a proposition is a matter of its being useful to believe. Throughout the twentieth century, philosophers used one or other version of this map to orient themselves and their students in the often complex and confusing debates about truth, even while acknowledging that the map may be incomplete in crucial respects (it does not include functionalist and pluralist views, for example). Our objection to the map is not that it is incomplete—although it obviously is—, but that it needs to be radically redrawn. In particular, the familiar division between coherence theories and correspondence theories needs to be rethought. The coherence theory is so often glibly dismissed as absurd that labelling someone as a coherence theorist is often seen as reason enough to ignore them.1 While none of the philosophers usually so labelled should be ignored, we shall argue (§3) that none of them actually held this view anyway. The difficulty—perhaps impossibility—of finding a genuine coherence theorist of truth strikes us as more than just an indication that this is a rare animal. Rather, it suggests the possibility of something significant, namely, that the only occupant of this position in historical space is a set of slogans; this would give us some reason to suppose that the logical space of theories is just as empty at this point..

This book analyses and defends the deflationist claim that there is nothing deep about our notion of truth. According to this view, truth is a 'light' and innocent concept, devoid of any essence which could be revealed by scientific inquiry. Cezary Cieśliński considers this claim in light of recent formal results on axiomatic truth theories, which are crucial for understanding and evaluating the philosophical thesis of the innocence of truth. Providing an up-to-date discussion and original perspectives (...) on this central and controversial issue, his book will be important for those with a background in logic who are interested in formal truth theories and in current philosophical debates about the deflationary conception of truth.

This paper by Theodore de Laguna presents and argues for the deflationary theory of truth. The paper was first published in French in 1922. The version published here is the original, English version of the paper and has been edited by Joel Katzav.

"Deflationism" has emerged as one of the most significant developments in contemporary philosophy. It is best known as a story about truth -- roughly, that the traditional search for its underlying nature is misconceived, since there can be no such thing. However, the scope of deflationism extends well beyond that particular topic. For, in the first place, such a view of truth substantially affects what we should say about neighboring concepts such as "reality," "meaning," and "rationality." And in (...) the second place, the anti-theoretical meta-philosophy that lies behind that view -- the idea that philosophical problems are characteristically based on confusion and should therefore be dissolved rather than solved -- may fruitfully be applied throughout the subject, in epistemology, ethics, the philosophy of science, metaphysics, and so on. The essays reprinted here were written over the last twenty five years. They represent Paul Horwich's development of the deflationary perspective and demonstrate its considerable power and fertility. They concern a broad array of philosophical problems: the nature of truth, realism vs. anti-realism, the creation of meaning, epistemic rationality, the conceptual role of "ought," probabilistic models of scientific reasoning, the autonomy of art, the passage of time, and the trajectory of Wittgenstein's philosophy. They appear as originally published except for the correction of obvious mistakes, the interpolation of clarifying material, and the inclusion of new footnotes to indicate Horwich's subsequent directions of thought.

The metaphysical dispute between moral realists and antirealists is cast in terms of properties: the realist holds that moral properties exist, the antirealist denies this claim. There is a longstanding philosophical dispute over the nature of properties, and the obscurity of properties may make the realist/antirealist dispute even more obscure. In the spirit of deflationary theories of truth, we can turn to a deflationary theory of properties in order to clarify this issue. One might reasonably worry (...) that such an account of properties would not be capable of properly characterizing disputes regarding the existence or nonexistence of genuine moral properties. In this paper, I will show that, within this framework, the traditional disputes over the existence of moral properties can be characterized in a far clearer fashion than is usually the case. A deflationary account of properties, along with an explanatory hierarchy of properties, makes the dispute in ontology clear. (shrink)

The existence of a close connection between results on axiomatic truth and the analysis of truth-theoretic deflationism is nowadays widely recognized. The first attempt to make such link precise can be traced back to the so-called conservativeness argument due to Leon Horsten, Stewart Shapiro and Jeffrey Ketland: by employing standard Gödelian phenomena, they concluded that deflationism is untenable as any adequate theory of truth leads to consequences that were not achievable by the base theory alone. (...) In the paper I highlight, as Shapiro and Ketland, the irreducible nature of truth axioms with respect to their base theories. But, I argue, this does not immediately delineate a notion of truth playing a substantial role in philosophical or scientific explanations. I first offer a refinement of Hartry Field’s reaction to the conservativeness argument by distinguishing between metatheoretic and object-theoretic consequences of the theory of truth and address some possible rejoinders. In the resulting picture, truth is an irreducible tool for metatheoretic ascent. How robust is this characterizaton? I test it by considering: a recent example, due to Leon Horsten, of the alleged explanatory role played by the truth predicate in the derivation of Fitch’s paradox; an essential weakening of theories of truth analyzed in the first part of the paper.

It is widely held that the normativity of truth and meaning puts a severe constraint on acceptable theories of these phenomena. This constraint is so severe, some would say, as to rule out purely ‘naturalistic’ or ‘factual’ accounts of them. In particular, it is commonly supposed that the deflationary view of truth and the use conception of meaning, in so far as they are articulated in entirely non-normative terms, must for that reason be inadequate.

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. (shrink)

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

In a recent paper, Haig and Borsboom explore the relevance of the theory of truth for psychological science. Although they conclude that correspondence theories of truth are best suited to offer the resources for making sense of scientific practice, they leave open the possibility that other theories might accomplish those same ends. I argue that deflationary theories of truth, which deny that there is any substantive property that unifies the class of truths, makes equally good (...) sense of scientific practice as the correspondence theory, but at lesser theoretical cost. I also argue that the considerations Haig and Borsboom draw on are better thought of as issues relevant to realism, and thus separate from the theory of truth. I conclude that while they are correct to engage questions about what makes true the various claims that arise in psychological research, they may do so without saddling themselves with a correspondence theory.

This dissertation defends the truth-conditional theory of meaning and the inflationary theory of truth it requires by explaining how truth-conditions could play an explanatory role in the account of the proper use of a language while being nevertheless metaphysically "lightweight" properties of sentences instituted by the way these sentences are used by the speakers of a language. Following the common division of approaches to truth into deflationary and inflationary, the dissertation begins in Chapter (...) One with a discussion of currently advocated deflationary theories. A general characterization of deflationism is developed that focuses on the deflationist's explanation of why certain attributions of truth-condition to the sentences of a language are assertible. This basic, meaning-theoretic deflationary commitment is distinguished from the metaphysically deflationary idea that truth is somehow not "robust" in the way that traditional inflationary theories take it to be. Chapter Two then argues that meaning-theoretic deflationism is best characterized by a less-noticed commitment to the claim that it is sufficient for adequacy in a theory of truth that it imply the attributions of truth-conditions discussed in Chapter One. In Chapter Three the relation of these basic deflationary commitments to the also common deflationary claim that meanings attributed with locutions like the English "means that", meanings that, in Hartry Field's phrase, "encapsulate truth-conditions" is considered, and it is argued that this latter view is actually not compatible with deflationism. ;Chapter Four examines the most prominent sorts of inflationary theory and finds them wanting. Chapter Five then discusses in a general way how a better inflationary theory could be developed; the central ideas are that truth-conditions play an explanatory role in the account of certain embedded uses of sentences, and that truth-conditions should be understood as instituted for sentences by the way that speakers use them. In Chapter Six the relevant sort of use is explained. The result is a view that is meaning-theoretically inflationary, in that truth-conditions play an explanatory role in the account of meaning, but metaphysically deflationary. (shrink)

On the normativity objection to Horwich’s minimalist theory of truth, his theory fails to capture the value of truth. In response to this objection, he argues that his minimalist theory of truth is compatible with the value of truth. On his view, the concept of truth is not constitutively normative, but the value of true beliefs can be explained instead by the belief-truth norm that we ought to want our beliefs to (...) be true, and the value of true beliefs expressed in this norm is a moral value. I accept a deflationary theory of truth, according to which truth is too thin a concept to be constituted by any substantial norms. Thus I agree that the concept of truth is not constitutively normative. In this paper, however, I argue that the alleged value of true beliefs can be better explained in terms of epistemic normativity rather than moral normativity. (shrink)

According to the truth-conduciveness problem of coherentism, the coherence theory of justification can hardly show that coherentist justification is truth-conducive. This problem is generally conceived as the most recalcitrant problem with the coherence theory. The purpose of this paper is to show that it does not pose a serious problem for a certain version of coherentism, namely a Sellarsian explanatory coherence theory of justification combined with the deflationary theory of truth. On this (...) version of coherentism, our epistemic goal is to gradually improve our conceptual framework so as to maximize its explanatory coherence, and there is no substantial norm of truth independent of the norms of justification, so that we cannot evaluate the truth-conduciveness of a belief independently of the norms of justification. I argue that this version of coherentism can cope with the truth-conduciveness problem. (shrink)

By a classical result of Kotlarski, Krajewski and Lachlan, pathological satisfaction classes can be constructed for countable, recursively saturated models of Peano arithmetic. In this paper we consider the question of whether the pathology can be eliminated; we ask in effect what generalities involving the notion of truth can be obtained in a deflationary truth theory (a theory of truth which is conservative over its base). It is shown that the answer depends on the (...) notion of pathology we adopt. It turns out in particular that a certain natural closure condition imposed on a satisfaction class—namely, closure of truth under sentential proofs—generates a nonconservative extension of a syntactic base theory (Peano arithmetic). (shrink)

The aim of this paper is to show that it’s not a good idea to have a theory of truth that is consistent but ω-inconsistent. In order to bring out this point, it is useful to consider a particular case: Yablo’s Paradox. In theories of truth without standard models, the introduction of the truth-predicate to a first order theory does not maintain the standard ontology. Firstly, I exhibit some conceptual problems that follow from so introducing (...) it. Secondly, I show that in second order theories with standard semantics the same procedure yields a theory that doesn’t have models. So, while having an ω- inconsistent theory is a bad thing, having an unsatisfiable theory of truth is actually worse. This casts doubts on whether the predicate in question is, after all, a truthpredicate for that language. Finally, I present some alternatives to prove an inconsistency adding plausible principles to certain theories of truth. (shrink)

In this paper, we propose and justify the cross‐linguistic study of the concept of truth through empirical studies of truth predicates, with results of such studies. We first conceptually explore the possibility of cross‐linguistic disagreement about truth purely due to linguistic norms governing truth predicates, which may imply a kind of pluralism about the concept of truth. We then consider the conditions under which we would be justified in inferring this sort of pluralism from the (...) fact of such cross‐linguistic disagreement. Next, we report results of three studies on the use of English “is true” and Japanese two truth predicates, as well as “is correct” and its Japanese counterpart. We then report another set of studies using a different vignette, where the radical cross‐linguistic difference observed in earlier studies disappeared. These data together suggest that the moral‐political factor in the truth‐bearer (utterance) strongly affects the uses of Japanese truth predicates but not those of English. Finally, we will discuss the implications of the studies and results reported here, and the empirical possibility of what we call lexical alethic pluralism, for debates over relativism, theories of meaning, and the deflationary and inflationary theories of truth.

A common objection against deflationism is that it cannot account for the fact that truth depends on reality. Consider the question ‘On what does the truth of the proposition that snow is white depend?’ An obvious answer is that it depends on whether snow is white. Now, consider what answer, if any, a deflationist can offer. The problem is as follows. A typical deflationary analysis of truth consists of biconditionals of the form ‘The proposition that p (...) is true iff p’. Such biconditionals tell us nothing about what the truth of the proposition that p might depend on. Therefore, it seems that a typical deflationist cannot give an answer. Since we know that an answer is available, this throws doubt over the adequacy of deflationism as an account of truth. Articulated here is a defence of deflationism against this objection. It is argued that although biconditionals of the sort mentioned do not explicitly state a dependency between truth and reality, they nevertheless convey one. The reason is that, given the context in which a deflationist invokes the biconditionals, such a dependency is implicated. A potential problem with this defence is that it leaves the deflationist still unable to give an account of what it is for truth to depend on reality. One might think that a deflationist can offer such an account by appealing to truthmaker theory but, it is argued below, truthmaker theory is unavailable to a deflationist. Instead, the deflationist should question the assumption that an account is available. (shrink)

Although a number of truth theorists have claimed that a deflationary theory of ‘is true’ needs nothing more than the uniform implication of instances of the theorem ‘the proposition that p is true if and only if p ’, reflection shows that this is inadequate. If deflationists can’t support the instances when replacing the biconditional with ‘because’, then their view is in peril. Deflationists sometimes acknowledge this by addressing, occasionally attempting to deflate, ‘because’ and ‘in virtue of’ (...) formulas and their close relatives. I examine what I take to be the most promising deflationist moves in this direction and argue that they fail. (shrink)

In this dissertation, I argue that we should be pluralists about truth and in turn, eliminativists about the property Truth. Traditional deflationists were right to suspect that there is no such property as Truth. Yet there is a plurality of pluralities of properties which enjoy defining features that Truth would have, were it to exist. So although, in this sense, truth is plural, Truth is non-existent. The resulting account of truth is indebted to (...) deflationism as the provenance of the suspicion that Truth doesn't exist. But it would be hasty to simply classify the account as deflationary. Each of the 'truth-like' properties that it recognizes is highly substantive--that is, complex and explanatorily potent. So we should deflate Truth by recognizing that it doesn't exist, but we should also recognize that one of the most vital tasks in truth theory is to discover the essences of the many truth-like properties. My aim here is to do precisely this. (shrink)

In recent decades deflationary theories of truth have been challenged with a technical argument based on the notion of conservativeness. In this paper, I shall stress that conservative extensions of theories and expandability of their models are not equivalent notions. Then, I shall argue that the deflationary thesis of the unsubstantiality of truth is better understood as leveraging on the stronger notion of expandability of models. Once expandability is involved in the argument, some notable consequences follow: (...) the strategy proposed by Hartry Field in response to the conservativeness objection is strongly undermined and even simpler proposals (such as theories based on standard t-sentences) are shown to be quite problematical. (shrink)

One of the popular explications of the deflationary tenet of ‘thinness’ of truth is the conservativeness demand: the declaration that a deflationary truth theory should be conservative over its base. This paper contains a critical discussion and assessment of this demand. We ask and answer the question of whether conservativity forms a part of deflationary doctrines.

It is widely believed that deflationary truth has no explanatory power. I will argue that it does. Specifically, I will consider some objections to deflationary truth having explanatory power, and argue that they fail. The position which will emerge is that the deflationary concept of truth is analogous to the concept of an average. Scientists take averages to be explanatory, and I will argue that the concept of deflationary truth is explanatory in (...) the same way. I then argue that this deflationary _concept_ of truth motivates a theory of the _property_ of truth which is metaphysically disunified, but that this is no obstacle to explanation. This leads to a way of understanding the deflationary/substantive distinction in terms of grounding. (shrink)

Aristotle’s words in the Metaphysics: “to say of what is that it is, or of what is not that it is not, is true” are often understood as indicating a correspondence view of truth: a statement is true if it corresponds to something in the world that makes it true. Aristotle’s words can also be interpreted in a deflationary, i.e., metaphysically less loaded, way. According to the latter view, the concept of truth is contained in platitudes like: (...) ‘It is true that snow is white iff snow is white’, ‘It is true that neutrinos have mass iff neutrinos have mass’, etc. Our understanding of the concept of truth is exhausted by these and similar equivalences. This is all there is to truth. In his book Truth (Second edition 1998), Paul Horwich develops minimalism, a special variant of the deflationary view. According to Horwich’s minimalism, truth is an indefinable property of propositions characterized by what he calls the minimal theory, i.e., all (nonparadoxical) propositions of the form: It is true that p if and only if p. Although the idea of minimalism is simple and straightforward, the proper formulation of Horwich’s theory is no simple matter. In this paper, I shall discuss some of the difficulties of a logical nature that arise. First, I discuss problems that arise when we try to give a rigorous characterization of the theory without presupposing a prior understanding of the notion of truth. Next I turn to Horwich’s treatment of the Liar paradox and a paradox about the totality of all propositions that was first formulated by Russell (1903). My conclusion is that Horwich’s minimal theory cannot deal with these difficulties in an adequate way, and that it has to be revised in fundamental ways in order to do so. Once such revisions have been carried out the theory may, however, have lost some of its appealing simplicity. (shrink)

Deflationists say that the equivalence between ‘p is true’ and p is all there is to the meaning of ‘true’. “Use” theories generally construe meaning as acceptance conditions. I argue: (i) there are certain obvious objections to a deflationary theory of truth so formulated; but (ii) they can be overcome if we employ a graded notion of use, i.e. a notion of assertability; but (iii) there appear to be certain further difficulties which cannot be overcome in this (...) way.

This book is a collection of important writings on deflationism, with a detailed introduction and an exhaustive annotated bibliography. Among philosophers concerned with the theory of truth, deflationist positions have quickly gained ground and have become the most popular. Yet heretofore there has been no single book to which the readers can go for a detailed, overall view of the entire phenomenon of deflationism. This is the only available map of the whole terrain of deflationism. -/- Deflationism is (...) a comparatively new approach, though it has its roots in the thinking of some philosophers in the early twentieth century. Deflationism rejects all the traditional theories of truth: the correspondence theory (truth corresponds with facts), the coherence theory (truth is membership of a coherent set of beliefs), the pragmatist theory is provability or verifiability). This book gives complete coverage to all the different varieties of deflationism, and to earlier philosophers who anticipated deflationism. The articles and exerpts include classic works by Frege, Ayer, Ramsey, Tarsk, and Quine, and recent works by the leading deflationist authors of today: Paul Horwich, Hartry Field, Stephen Schiffer, Robert Brandom, and Stephen Leeds.

There is an important family of semantic notions that we apply to thoughts and to the conceptual constituents of thoughts - as when we say that the thought that the Universe is expanding is true. Thought and World presents a theory of the content of such notions. The theory is largely deflationary in spirit, in the sense that it represents a broad range of semantic notions - including the concept of truth - as being entirely free (...) from substantive metaphysical and empirical presuppositions. At the same time, however, it takes seriously and seeks to explain the intuition that there is a metaphysically or empirically 'deep' relation linking thoughts to reality. Thus, the theory represents a kind of compromise between deflationism and versions of the correspondence theory of truth. This book will appeal to students and professionals interested in the philosophy of logic and language. (shrink)
