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.

Minimalists about truth contend that traditional inflationary theories systematically fail to explain certain facts about truth, and that this failure licenses a ‘reversal of explanatory direction’. Once reversed, they purport that their own minimal theory adequately explains all of the facts involving truth. But minimalists’ main objection to inflationism seems to misfire, and the subsequent reversal of explanatory direction, if it can be made sense of, leaves minimalism in no better explanatory position; and even if the objection were serviceable and (...) the reversal legitimate, minimalists’ adequacy thesis is still implausible.

Philip Kitcher has argued for a causal correspondence view of truth, as against a deflationary view, on the grounds that the former is better poised than the latter to explain systematically successful patterns of action. Though Kitcher is right to focus on systematically successful action, rather than singular practical successes, he is wrong to conclude that causal correspondence theories are capable of explaining systematic success. Rather, I argue, truth bears no explanatory relation to systematic practical success. Consequently, the causal correspondence (...) view is not in a better position to explain success than the deflationary view; theories of truth are the wrong place to look for explanations of systematic practical success.

ABSTRACT According to a prominent objection, deflationist theories of truth can’t account for the explanatory connection between true belief and successful action [Putnam 1978]. Canonical responses to the objection show how to reformulate truth-involving explanations of particular successful actions, so as to omit any mention of truth [Horwich 1998]. According to recent critics, though, the canonical strategy misses the point. The deflated paraphrases lack the generality or explanatory robustness of the original explanatory appeals to truth [Kitcher 2002; Lynch 2009; Gamester (...) 2018]. This article diagnoses the canonical response’s failure and shows how deflationists can make sense of appeals to truth in explaining practical success, in all of their generality and robustness, without construing truth as a substantial property.

The core of alethic pluralism is the idea that truth is a different property in some discourses from others. Orthodox pluralists such as Crispin Wright and Michael Lynch share three commitments that motivate their view. One is Ecumenicalism, the view that scientific and moral claims are both truth-apt. The second is Occasional Realism, the view that truth in science is a matter of justification-independent, accurate representation, while truth in ethics is a matter of ideal epistemic justifiability. The third is Normativism, (...) the view that truth-attributions are normative in a way deflationary theories cannot accommodate. This paper articulates the “aletheiological dilemma” for orthodox pluralists. The dilemma arises when we ask whether the truth-property relevant to truth-attributions is epistemic. Occasional Realism requires it not be, but Normativism and the pluralists’ other commitments require truth for truth-attributions to be a matter of ideal justifiability. The paper also considers some ways around the dilemma, none of which looks very promising for pluralists. (shrink)

In computer simulations of physical systems, the construction of models is guided, but not determined, by theory. At the same time simulations models are often constructed precisely because data are sparse. They are meant to replace experiments and observations as sources of data about the world; hence they cannot be evaluated simply by being compared to the world. So what can be the source of credibility for simulation models? I argue that the credibility of a simulation model comes not only (...) from the credentials supplied to it by the governing theory, but also from the antecedently established credentials of the model building techniques employed by the simulationists. In other words, there are certain sorts of model building techniques which are taken, in and of themselves, to be reliable. Some of these model building techniques, moreover, incorporate what are sometimes called “falsifications.” These are contrary-to-fact principles that are included in a simulation model and whose inclusion is taken to increase the reliability of the results. The example of a falsification that I consider, called artificial viscosity, is in widespread use in computational fluid dynamics. Artificial viscosity, I argue, is a principle that is successfully and reliably used across a wide domain of fluid dynamical applications, but it does not offer even an approximately “realistic” or true account of fluids. Artificial viscosity, therefore, is a counter-example to the principle that success implies truth – a principle at the foundation of scientific realism. It is an example of reliability without truth.

Apparently, aiming to comply with the norm ‘Believe that P if and only if the proposition that P is true’ can hardly differ from aiming to comply with the norm ‘Believe that P if and only if the proposition that P is epistemically justified’. So one may be tempted to agree with Richard Rorty that the distinction between truth and justification is pragmatically useless because it cannot make any difference ‘when the question is about what I should believe now’. I (...) resist this conclusion by arguing that the distinction between truth and justification is pragmatically useful even if the two properties are indeed normatively coincident. The argument I offer turns on the claim that truth plays an explanatory role that justification is inherently incapable of playing. However, my contention is not just that the distinction between truth and justification is pragmatically useful because truth is a bona fide explanatory notion. It is that the distinction between truth and justification is pragmatically useful because the realization that the former plays an explanatory role that the latter is inherently incapable of playing gives access to reasons which would otherwise escape our attention. If truth is a bona fide explanatory notion, the distinction between truth and justification is pragmatically useful because it is precisely when the question is about what I should believe now that attending to such a distinction will often make a difference – and it will make a difference even if the two properties are in fact normatively coincident.

, Philip Kitcher has argued that science ought to meet both the epistemic goals of significant truth and the nonepistemic goals of serving the interests of a democratic society. He opposes this science as servant model to both the theology of science as source of salvific truth and the theology of science as anti-Christ. In a recent critical comment, Paul A. Roth argues that Kitcher remains entangled in the theology of salvific truth, not realizing that its goal is either vacuous (...) or unattainable. Instead of theologies, Roth proposes demythologization. In the end, science attains neither truth nor value, for these goals are incomprehensible and unattainable. Consequently, science’s goals are entirely pedestrian and without special interest. Adopting Kitcher’s own scientific naturalistic epistemology, the author argues for a naturalized theology of science, using a science as mediator model, in which both nature and scientist have a role in the acquisition of significant truth. Key Words: epistemic values • Kitcher • nonepistemic values • Roth • science and values • scientific realism • scientific truth. (shrink)

This paper argues that Philip Kitcher's epistemology of mathematics, codified in his Naturalistic Constructivism, is not naturalistic on Kitcher's own conception of naturalism. Kitcher's conception of naturalism is committed to (i) explaining the correctness of belief-regulating norms and (ii) a realist notion of truth. Naturalistic Constructivism is unable to simultaneously meet both of these commitments.

Most philosophical work on social ontology continues to be done without much connection to social scientific concerns. This special issue, however, calls for attention to a naturalized metaphysics, one based on the best science we have. It follows that a naturalized social metaphysics should begin with the best social science available. In contrast with the physical sciences, however, the best social science is not so clear. Thus, this paper acquaints professional philosophers with some of the prominent metaphysical views extant in (...) the social sciences; the ways that more philosophically oriented social scientists engage them; and how professional philosophers might contribute.In particular, the paper covers several arguments especially relevant to a naturalized social metaphysics. One argument suggests that folk intuitions cannot be excluded from consideration. In fact, in the social sphere, it may be that scientific concepts not only cannot always trump folk conceptions but actually must be constrained by them. The paper further introduces arguments defending not only metaphysically real levels of being but also the metaphysical reality of the categories of social science. Finally, the paper will introduce an argument that beyond culture and individual agency, social being also includes structure as a distinct category. (shrink)

What is the relation between coherence and truth? This paper rejects numerous answers to this question, including the following: truth is coherence; coherence is irrelevant to truth; coherence always leads to truth; coherence leads to probability, which leads to truth. I will argue that coherence of the right kind leads to at least approximate truth. The right kind is explanatory coherence, where explanation consists in describing mechanisms. We can judge that a scientific theory is progressively approximating the truth if it (...) is increasing its explanatory coherence in two key respects: broadening by explaining more phenomena and deepening by investigating layers of mechanisms. I sketch an explanation of why deepening is a good epistemic strategy and discuss the prospect of deepening knowledge in the social sciences and everyday life. (shrink)

Le défi le plus important auquel doivent faire face les tenants d’une conception déflationniste de la vérité est l’argument de l’action réussie. Celui-ci fut défendu par Kitcher : afin de rendre compte d’une action réussie, il faudrait expliquer pourquoi une et une même action peut être à la fois psychologiquement et effectivement pertinente. Pour lui, seule la vérité-adéquation permet de répondre à cette exigence. Dans cet article, je soutiens qu’afin de rendre compte d’une action réussie, il convient d’expliquer en quoi (...) l’action d’un agent lui est un moyen approprié d’atteindre ses fins, et que cette explication même, dans le cadre d’une conception déflationniste, suffit à répondre à l’exigence théorique de Kitcher.

I argue that one good reason for Scientific Realists to be interested in correspondence theories is the hope they offer us of being able to state and defend realistic theses in the face of well-known difficulties about modern physics: such theses as, that our theories are approximately true, or that they will tend to approach the truth. I go on to claim that this hope is unlikely to be fulfilled. I suggest that Realism can still survive in the face of (...) these difficulties, as a claim about the kind of theories we want to aim for. I relate this conception of Realism to various contemporary discussions, both by realists and antirealists. (shrink)

QC 20120521. Review of 'Science in the Age of Computer Simulation' by Eric Winsberg.

A common objection against deflationist theories of truth is that they cannot do justice to the correspondence intuition, i.e. the intuition that there is an explanatory relationship between, for instance, the truth of ‘Snow is white’ and snow's being white. We scrutinize two attempts to meet this objection and argue that both fail. We then propose a new response to the objection which, first, sheds doubt on the correctness of the correspondence intuition and, second, seeks to explain how we may (...) nonetheless have come to have that intuition.

Inflationists have argued that truth is a causal-explanatory property on the grounds that true belief facilitates practical success: we must postulate truth to explain the practical success of certain actions performed by rational agents. Deflationists, however, have a seductive response. Rather than deny that true belief facilitates practical success, the deflationist maintains that the sole role for truth here is as a device for generalisation. In particular, each individual instance of practical success can be explained only by reference to a (...) relevant instance of a T-schema; the role of truth is just to generalise over these individualised explanations. I present a critical problem for this strategy. Analogues of the deflationist’s individualised explanations can be produced by way of explanation of coincidental instances of practical success where the agent merely has the right false beliefs. By deflationary lights, there is no substantive explanatory difference between such coincidental and non-coincidental instances of practical success. But the non-/coincidental distinction just is an explanatory distinction. The deflationist’s individualised explanations of non-coincidental instances of practical success must therefore be inadequate. However, I argue that the deflationist’s prospects for establishing an explanatory contrast between these cases by supplementing her individualised explanations are, at best, bleak. The inflationist, by contrast, is entitled to the obvious further explanatory premise needed to make sense of the distinction. As such, pending some future deflationary rejoinder, the deflationary construal of the principle that true belief facilitates practical success must be rejected; and with it the deflationary conception of truth.

This paper motivates and defends alethic nihilism, the theory that nothing is true. I first argue that alethic paradoxes like the Liar and Curry motivate nihilism; I then defend the view from objections. The critical discussion has two primary outcomes. First, a proof of concept. Alethic nihilism strikes many as silly or obviously false, even incoherent. I argue that it is in fact well-motivated and internally coherent. Second, I argue that deflationists about truth ought to be nihilists. Deflationists maintain that (...) the utility of the truth predicate is exhausted by its expressive role, and I argue that the truth predicate can still play this expressive role even if nothing is true. As such, deflationists do not stand to lose anything by accepting nihilism. Since they also stand to gain an elegant solution to the alethic paradoxes, on balance deflationists ought to be nihilists.

In this article I examine several issues concerning reliabilism and deflationism. I critique Alvin Goldman's account of the key differences between correspondence and deflationary theories and his claim that reliabilism can be combined only with those truth theories that maintain a commitment to truthmakers. I then consider how reliability could be analysed from a deflationary perspective and show that deflationism is compatible with reliabilism. I close with a discussion of whether a deflationary theory of knowledge is possible.

This paper investigates the nature of scientific realism. I begin by considering the anomalous fact that Bas van Fraassen’s account of scientific realism is strikingly similar to Arthur Fine’s account of scientific non-realism. To resolve this puzzle, I demonstrate how the two theorists understand the nature of truth and its connection to ontology, and how that informs their conception of the realism debate. I then argue that the debate is much better captured by the theory of truthmaking, and not by (...) any particular theory of truth. To be a scientific realist is to adopt a realism-relevant account of what makes true the scientific theories one accepts. The truthmaking approach restores realism’s metaphysical core—distancing itself from linguistic conceptions of the debate—and thereby offers a better characterization of what is at stake in the question of scientific realism.

We defend deflationism about truth against a pressing challenge, which is to explain how deflationists can understand the role that the _concept_ of truth appears to play in accounts of several other philosophically important concepts. We provide three strategies that deflationists can employ in response to the specific challenge regarding assertion that has been raised in several recent articles, viz., that the truth concept plays an ineliminable explanatory role in an account of assertion. We then show how to extend our (...) strategies to accounts of other central philosophical concepts, by applying them to accounts of belief, knowledge, and logical validity. The result is a set of recipes for deflationists about truth to employ in developing responses to worries that might be raised about the explanatory role of the truth concept. (shrink)

The Linda paradox is a key topic in current debates on the rationality of human reasoning and its limitations. We present a novel analysis of this paradox, based on the notion of verisimilitude as studied in the philosophy of science. The comparison with an alternative analysis based on probabilistic confirmation suggests how to overcome some problems of our account by introducing an adequately defined notion of verisimilitudinarian confirmation.

I defend the correspondence theory of truth, according to which a statement’s truth consists in a relation of correspondence with extralinguistic fact. There are well-known objections to this view, which I consider and rebut, and also important rival accounts, principal among which are so-called deflationist theories and epistemic theories. Epistemic theories relate the concept of truth to our state of knowledge, but fail, I argue, to respect the crucial distinction between a criterion of truth and the meaning of truth: the (...) view that one cannot do semantics, or metaphysics, without addressing epistemic issues is rejected by this work. Against epistemic theories, I illustrate how truth is independent of epistemic considerations. Deflationism is the more popular of the rival accounts and has gained considerable momentum over the past two decades. It is therefore dealt with in greater detail by this work. Deflationist theories exploit the paradigmatic ‘“Snow is white” is true iff snow is white’ biconditional to argue for an insubstantialist account, according to which truth is conservative with respect to non-semantical facts. On this view, truth’s raison d’être is merely to perform the useful expressive function of generalising over possibly infinite sets of assertions. Against deflationist theories, I claim that the work done by Jeffrey Ketland and Stewart Shapiro conclusively demonstrates how truth is informationally additive over non-semantic facts, while deflationism itself is also an excessively impoverishing theory, inadequate to the tasks it purports to accomplish. This work also defends the thesis that Alfred Tarski’s well-known theory of truth is an authentic correspondence theory. To say this is to say that the clauses of a Tarskian truth-definition can be interpreted in terms of a relation of correspondence that holds between true sentences and the states of affairs they describe. I provide a precise account of what the correspondence in question consists in, claiming that true sentences are homomorphic images of facts, i.e. a true sentence represents, in a form-preserving manner, the truth-making facts in it. This gives precise expression to Wittgenstein’s thesis that true sentences picture the world. (shrink)

I offer an explicit account of the underdetermination thesis as well as of the many challenges it poses to scientific realism; a way to answer to these challenges is explored and outlined, by shifting attention to the content of theories. I argue that, even if we have solid grounds (as I contend we do) to support that some varieties of the underdetermination thesis are true, scientific realism can still offer an adequate picture of the aims and achievements of science.

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

This paper critically reviews Philip Kitcher's most recent epistemology of science, real realism . I argue that this view is unstable under different understandings of the term 'representation', and that the arguments offered for the position are either unsound or invalid depending on the understanding employed. Suitably modified those arguments are however convincing in favor of a deflationary version of real realism, which I refer to as the bare view . The bare view accepts Kitcher's Galilean strategy, and the ensuing (...) commitment to the existence of unobservables; but it does not trade on a correspondence or copy theory of representation. So the bare view, unlike real realism, does not entail that our representations match reality even approximately. (shrink)

Metaphysics has had a long history of debate over its viability, and substantivity. This thesis explores issues connected to the realism question within the domain of metaphysics, ultimately aiming to defend a realist, substantive metaphysics by responding to so-called deflationary approaches, which have become prominent, and well supported within the recent metametaphysical and metaontological literature. To this end, I begin by examining the changing nature of the realism question. I argue that characterising realism and anti-realism through theories of truth unduly (...) places epistemology prior to ontology, and is unwarranted in assuming a non-neutrality between theories of truth and positions within the realism debate. I therefore propose a characterisation of realism and anti-realism understood through truthmaking. This produces a suitable working characterisation of realism that will be used within the remainder of this project. In the second section, I trace the historical influences upon current deflationary approaches to metaphysics, most prominently those of Carnap, and Putnam. I argue that Quine’s supposed attack on Carnap’s anti-metaphysical thought fails, and show how current deflationary thought, most prominently exhibited by Hirsch, came to focus on linguistically derived concerns over the substantivity of metaphysics. In the third section, I outline a number of issues for the deflationist, and defend the coherency and legitimacy of the unrestricted existential quantifier. Focusing on the linguistic aspect of deflationism, I argue that the conception of language that the deflationist relies upon lacks suitable empirical and theoretical support within linguistics and other related domains. Furthermore, I suggest that linguistic analysis in fact supports the claim that the quantifier carries no inherent restrictions. This restores our ability to suitably posit the unrestricted existential quantifier, as a quantifier wherein the domain is only restricted by metaphysically substantive restrictions. Through this, I argue that metaphysics is a substantive domain of discourse. Lastly, I sketch a positive account of how, under an empirically and theoretically justified conception of language, metaphysics can be coherently held to be a realist, substantive enterprise, contra claims that hold that the nature of language inherently prevents metaphysics being considered to be a substantive domain of discourse.

En los últimas décadas se han elaborado diferentes teorías al interior de la filosofía de la ciencia que pretenden explicar cuál es la mejor manera de entender el progreso científico cognitivo. De entre ellas sobresalen por su extensión, especificidad y alcance las propuestas de Larry Laudan y de Philip Kitcher. Laudan, siguiendo a Karl Popper, Thomas S. Kuhn y retomando varias ideas de Imre Lakatos, defendió una perspectiva funcionalista a partir de la cual propuso la resolución de problemas como el (...) mejor criterio cognitivo para evaluar el progreso científico. Por su parte, Kitcher propuso como criterio del progreso científico la producción de enunciados significativos y verdaderos, defendiendo - no sin ambigüedad - un tipo de realismo científico. En este trabajo pretendo mostrar que los criterios epistémicos, a diferencia de los criterios no epistémicos, complican innecesariamente el análisis de la progresividad científica. (shrink)

The topic of truth has long been thought to be connected to scientific realism and its opposition. In this essay, I discuss the various ways that truth might be related to realism. First, I consider how truth might be of use when defining scientific realism and its opposition. Second, I consider whether various stances regarding realism require specific stances on the nature of truth. I survey "neutralist" views that argue that one's stance on realism is independent of one's view on (...) truth, and partisan positions that claim that one's attitude on realism is, in part, determined by one's theory of truth. Though partisan views have been popular, and defended by seminal figures such as Thomas Kuhn, Richard Rorty, Hilary Putnam, and Arthur Fine, I raise a number of objections for them. (shrink)

In Science, Truth, and Democracy (2001a), Kitcher moderates the strongest ontological realist thesis he defended in The Advancement of Science (1993a), with the aim of making compatible the correspondence theory of truth with conceptual relativity. However, it is not clear that both things could be harmonized. If our knowledge of the world is mediated by our categories and concepts; if the selection of these categories and concepts may vary according to our interests, and they are not the consequence of the (...) existence of certain supposed natural kinds or some intrinsic structure of the world, it is very problematic to establish what our true statements correspond to. This paper analyzes the transformation in Kitcher's realism and expounds the main difficulties in this project. Finally, a modality of moderate ontological realism will be proposed that, despite of keeping the sprit of the conceptual relativity, is strong enough to support the correspondence theory of truth.

Realism comes in many varieties, in science and elsewhere. Van Fraassen's influential formulation took scientific realism to include the view that science aims to give us, in its theories, a literally true story of what the world is like. So understood, a quantum realist takes quantum theory to aim at correctly representing the world: many would add that its success justifies believing this representation is more or less correct. But quantum realism has been understood both more narrowly and more broadly. (...) A pragmatist considers use prior to representation and this has prompted some to dub pragmatist views anti-realist, including the view of quantum theory I have been developing recently. But whether a pragmatist view of quantum theory should be labeled anti-realist depends not only on its ingredients but also on how that label should be applied. Pragmatism offers a healthy diet of quantum realism. (shrink)
