In this work I reply to Zoltán Vecsey’s criticisms of the semantic account of fictional names I put forward in Orlando. The main tenet of that proposal is that fictional names refer to individual concepts, which I understand in terms of mental files. In Vecsey, the author presents three main objections: no referential shift can be ascribed to fictional names, fictional names are supposed to play two conflicting functions, and the mental file framework is incompatible with an antirealist view of (...) fictional objects. Although the objections are deep and thoughtful, the challenge they involve can be met if certain aspects of the proposal are clarified and developed. (shrink)

Economics is a controversial scientific discipline. One of the traditional issues that has kept economists and their critics busy is about whether economic theories and models are about anything real at all. The critics have argued that economic models are based on assumptions that are so utterly unrealistic that those models become purely fictional and have nothing informative to say about the real world. Many also claim that an antirealist instrumentalism (allegedly outlined by Milton Friedman in 1953) (...) justifying such unrealistic models has become established as the semi-official practitioners' philosophy of conventional economics. Others argue that what is the case in the economy and the way economics relates to it are socially constructed such that there is no economics-independent way the world worls or truths about it. On both of these pictures, realism would seem to have little do with economics. These pictures are too simplistic. There is more realism in and about economics than first would appear. To see this requires not just looking mere closely, but also adjusting one's conception of scientific realism. It also requires taking a critical stance on much of what economicsts themselves and other commentators have claimed. Yet, historically, there is much wisdom available in the philosophical self-image of the discipline. (shrink)

It is often assumed that chemistry was a typical positivistic science as long as chemists used atomic and molecular models as mere fictions and denied any concern with their real existence. Even when they use notions such as molecular orbitals chemists do not reify them and often claim that they are mere models or instrumental artefacts. However a glimpse on the history of chemistry in the longue durée suggests that such denials of the ontological status of chemical entities do not (...) testify for any specific allegiance of chemists to positivism. Rather it suggests that the dilemma positivism vs realism is inappropriate for characterizing the ontology of chemistry. This alternative shaped at the turn of the twentieth century in the context of controversies about atomic physics does not take into account the major concern of chemists, i.e. making up things. Only by considering what matters for chemists, their matters of concern rather than their matter theories, can we expect to get an insight on their ontological assumptions. The argumentation based on historical data is twofold. It is wellknown that generating new substances out of initial ingredients which is the raison d'être of chemistry raised a vexing puzzle which has been alternatively solved with the Aristotelian notion of mixt and the Lavoisieran notion of compound. I argue that an essential tension remains intrinsic in chemistry between the two conceptual frameworks. The second section tries to make sense of the long tradition in chemistry of ontological noncommitment. I argue that what is usually considered as a denial of the existence of the basic units of matter would be better characterized as a focus on more important actors on the chemical stage. (shrink)

The debate between realists and anti-realists about fictional entities is important partly because it connects with debates about the nature of reference. According to the descriptivist model held by Fregeans, a name has reference to an object due to the connection of that name with a description, which is met by the relevant object. According to the causal-communicative model held by Millians, a name refers in virtue of a chain of reference linking that name to a referent. In (...) the case of fictional entities, it is a matter of debate whether the entities in question exist or not. Traditionally, Millians have had trouble dealing with antirealism about fictional entities. I argue for a simple realist theory, ‘bare-bones artifactualism’, according to which fictional entities are simple abstract ‘counters’. Each of these simple abstract counters has only those intrinsic properties that other such simple abstract counters also have, except for one distinctive intrinsic property. This one distinctive intrinsic property is a number-bearing property that marks out the abstract counter’s identity, distinct from all other such abstract counters. The number-bearing property allows us to do with abstract counters what spatiotemporal situatedness allows us to do with concrete counters: it allows us to treat the abstract counters as individuals. In support of such artifactualism, I discuss the following considerations: its ontological simplicity; its parallels in our other practices; and its explanatory promise. (shrink)

The choice between realism and instrumentalism is at the core of concerns about how our scientific models relate to reality: Do our models aim to be literally true descriptions of reality, or is their role only as useful instruments for generating predictions? Realism about X, roughly speaking, is the claim that X exists and has its nature independent of our interests, attitudes, and beliefs. An instrumentalist about X denies this. She claims that talk of X (...) should be understood as no more than a useful locution for generating predictions, such talk should not be understood as taking on a commitment to the existence of X. According to an instrumentalist, we should either flatly not believe that X is out there, or else suspend judgement about the existence of X. The most we need acknowledge is that talk of X is useful in making predictions. The question of realism vs. instrumentalism can be asked about almost any theoretical entity in science. It is likely, and seems reasonable, that different answers will be given in different cases. Someone may wish to be a realist about certain theoretical entities (e.g. electrons), but an instrumentalist about others (e.g. centres of gravity). Not every noun-phrase in a scientific theory should be taken as expressing an ontological commitment. Psychological theories are no exception. Almost every theoretical posit in psychology has been questioned as to whether it is really out there or just a useful theoretical fiction. In this entry, I will focus on two major theoretical posits in psychology: (a) propositional attitudes (e.g. beliefs, desires) and (b) conscious states (qualia). (shrink)

This paper distinguishes three concepts of "race": bio-genomic cluster/race, biological race, and social race. We map out realism, antirealism, and conventionalism about each of these, in three important historical episodes: Frank Livingstone and Theodosius Dobzhansky in 1962, A.W.F. Edwards' 2003 response to Lewontin (1972), and contemporary discourse. Semantics is especially crucial to the first episode, while normativity is central to the second. Upon inspection, each episode also reveals a variety of commitments to the metaphysics of race. We (...) conclude by interrogating the relevance of these scientific discussions for political positions and a post-racial future. (shrink)

In this introduction, I consider different problems posed by the use of singular terms in fiction (section 1), paying especial attention to proper names and, in particular, to names of real people, places, etc. As we will see (section 2), descriptivist and Millian theories of reference face different kinds of problems in explaining the use of fictional names in fiction-related contexts. Moreover, the task of advancing a uniform account of names in these contexts—an account which deals not only (...) with fictional names but also with “real” names—will prove to be very hard no matter whether we favour realist or antirealist intuitions about fictional discourse (section 3). Section 4 offers an overview of the content of this volume, with emphasis on the discussion between Manuel García-Carpintero and Stacie Friend about the meaning of “real” names in fiction-related contexts, the main topic of the Third Blasco Disputatio.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Towards a Realist Philosophy of History by Adam TimminsAviezer TuckerTIMMINS, Adam. Towards a Realist Philosophy of History. Lanham, Md.: Lexington Books, 2022. 192 pp. Cloth, $95.00The debate about scientific realism, whether science represents reality or just discovers measurements and correlations that are followed by theoretical stories about them, is at the center of the philosophy of science. One potent and frequently discussed antirealist argument has (...) been Larry Laudan’s “pessimistic induction”: Historically, all scientific theories, especially in physics, have been proven false. Hence, all contemporary scientific theories will be proven false and science cannot represent reality. This pessimistic induction relies on knowledge of the history of science, on historiographic realism. Luckily for the pessimistic induction, the history of historiography, the scientific representation of the human past, supports an optimistic induction: Since the revolutions associated with Ranke in historiography, Lyle in geological history, and Darwin in biological history, the historical sciences have made progress but have not [End Page 368] overhauled the founders’ representations of the past. We know more about the human past than Ranke did and much more about the biological past than Darwin did, but the modern historical sciences have not overturned their theories and conclusions. Though there are many new methodologies, historians still go to the archives to compare primary sources, and biologists still study fossils and assume natural selection.Though scientific antirealism assumes historiographic realism, it has received scant philosophic attention. Often it is perceived or presented as a naive “empiricist” concept of historiography that imagines historians “observe” history and then describe it in historiography. Radical antirealist theories of historiography that reduce it to fiction, myth, or manipulative ideology use this image of realism as naive empiricism to dialectically support its equally naive antirealist antithesis. Both ignore the evidential, mostly testimonial, justifications of historiography.Adam Timmins’s project is to articulate and justify a sophisticated historiographic realism that fits historiographic practices and premises. He argues that historiography is “successful in providing information and understanding about the historical past that is constrained by and reflects what actually happened in the past itself.”Timmins’s historiographic realism springs out of the philosophy of language rather than epistemology or philosophy of science. This distinguishes it from Murray Murphey’s historiographic realism, which argued that historiographic ontology is theoretical. Famously, Murphey compared George Washington to the electron as two well-corroborated but unobservable theoretical entities. Timmins retorts that Washington is a proper name and not a theoretical concept, and it is impossible to conduct experiments with Washingtons. Timmins inquires how the language historians use may be interpreted as referring to past events and how historiography can represent history. He does not devote much attention to how historians justify their statements about history to a degree that may warrant a realistic interpretation of historiography. Rather, Timmins assumes so. He proceeds through polemical dialogues with philosophers of historiography who took antirealist stances like Leon Goldstein, Frank Ankersmit, and Jouni Kuukkanen.Timmins’s realism is founded on the belief in a universally accepted core of historiographic facts. He does not inquire about the theoretical foundations of historiographic inferences that allow the emergence of such a consensus. Rather than consider historiographic epistemology, the critical methods of historiography, Timmins considers linguistic communities and entrenched uses of language. He confronts the problem of reference to the past in the absence of its perception by asserting that historiographic representations are of “mental files” that have names (for example, “the Renaissance,” “the Second World War”) and evolving core facts about those historical events (for example, Petrarch and Da Vinci in the Renaissance, the main battles in the war). Though the exact contents of these files may differ between historians, they still refer to the same events and have the same labels. Timmins suggests that experts gradually introduce fluid norms of reference on the basis of broadly accepted facts [End Page 369] whose references caused information chains that led to them. He suggests that complex or colligated concepts are in the mind but refer through mediation to some directly referenced events. For example, the First World War is a concept that through the mediation of facts like its main battles refers to real... (shrink)

At first blush, the idea that fictions play a role in science seems to be off the mark. Realists and antirealists alike believe that science instructs us about how the world is. Fiction not only seems to play no role in such an endeavour; it seems to detract from it. The aims of science and fiction seem to be diametrically opposed and a view amalgamating the two rightly seems to be the cause of discomfort and concern.

Scientific realists believe both what a scientific theory says about observables and unobservables. In contrast, scientific antirealists believe what a scientific theory says about observables, but not about unobservables. I argue that scientific realism is a more useful doctrine than scientific antirealism in science classrooms. If science teachers are antirealists, they are caught in Moore’s paradox when they help their students grasp the content of a scientific theory, and when they explain a phenomenon in terms (...) of a scientific theory. Teachers ask questions to their students to check whether they have grasped the content of a scientific theory. If the students are antirealists, they are also caught in Moore’s paradox when they respond positively to their teachers’ questions, and when they explain a phenomenon in terms of a scientific theory. Finally, neither teachers nor students can understand phenomena in terms of scientific theories, if they are antirealists. (shrink)

Up until recently social scientists took it for granted that their task was to account for the social world as objectively as possible: they were realists in practice if not always in their methodological sermons. This situation started to change in the 1960s, when a number of antirealist philosophies made inroads into social studies. -/- This paper examines critically the following kinds of antirealism: subjectivism, conventionalism, fictionism, social constructivism, relativism, and hermeneutics. An attempt is made to show that these (...) philosophies are false and are causing serious damage to social studies. -/- Next the subjective interpretation of probability is analyzed as a case of subjectivism. An approach to the subjective perception of justice is sketched as an example of the objective study of subjective experience. -/- Finally, the three main varieties of realism — naive, critical, and scientific — are outlined. It is argued that the scientific attitude involves scientific realism, which is put in practice even by scholars who, like Weber and Simmel, called themselves antirealists. (shrink)

THE PHILOSOPHIC POSITION of which this essay is a partial expression shows science to be realistic in certain circumstances and antirealistic in others. But the position is not so irenic as this beginning might suggest. For one thing, the realism upon which this view of science depends, which I call radical realism, is different from any of the versions proposed over the years by the forces of realism in that controversy. For another, the antirealism envisioned for (...) some of the multiform occasions of science is not in the least a version of the well-known antirealism of the linguistic consensus but rather a modified antirealism that paradoxically depends for its clarity and force on that same radical realism. I have given some account of radical realism in earlier papers and books, but its full application to science is left for a forthcoming book. The present paper makes the point that it is impossible to reach a just settlement of the realism vs antirealism case--whether construed narrowly, as an issue for philosophy of science, or broadly, as an issue for the entire rational enterprise--if it is tried in the venue of the linguistic consensus.

Scientific realists use the “no miracle argument” to show that the empirical and pragmatic success of science is an indicator of the ability of scientific theories to give true or truthlike representations of unobservable reality. While antirealists define scientific progress in terms of empirical success or practical problem-solving, realists characterize progress by using some truth-related criteria. This paper defends the definition of scientific progress as increasing truthlikeness or verisimilitude. Antirealists have tried to rebut realism with the “pessimistic metainduction”, but (...) critical realists turn this argument into an optimistic view about progressive science. (shrink)

This article questions whether, once the conception of metaphysics as grounded in the philosophy of language has been jettisoned, Dummett's arguments against semantic realism can retain any relevance to the realist/antirealist debate. By focussing on realism about the external world as an example, it reaches the conclusion that even without Dummett's conception of philosophy as grounded in the theory of meaning, his arguments against semantic realism do retain a limited but nevertheless genuine significance for the metaphysical (...) debate. It emerges, though, that a certain key assumption, connecting the notions of linguistic understanding and knowledge, and necessary if Dummett's arguments are to have even this limited significance, is both underexplained and underdefended. The article concludes with some brief remarks on the cogency of the manifestation argument against semantic realism. (shrink)

Scientific Realism and Antirealism Debates about scientific realism concern the extent to which we are entitled to hope or believe that science will tell us what the world is really like. Realists tend to be optimistic; antirealists do not. To a first approximation, scientific realism is the view that well-confirmed scientific theories are approximately true; … Continue reading Scientific Realism and Antirealism →.

Manuel García Carpintero defends a form of antirealism for the explicit talk and thought both about fictional entities and scientific models: a version of StephenYablo’s figuralist brand of factionalism. He argues that, in contrast with pretense-theoretic fictionalist proposals, on his view, utterances in those discourses are straightforward assertions with straightforward truth-conditions, involving a particular kind of metaphors or figurative manner. But given that the relevant metaphors are all but “dead”, this might suggest that the view is after all (...) realist, committed to referents of some sort for singular terms in the relevant discourses. He revisits these issues from the perspective of the more recent work on them and applies his view to recent debates in semantics on the role and adequacy of supervaluationist models of indeterminacy.

There are realist and antirealist interpretations of the free energy principle (FEP). This paper aims to chart out a structural realist interpretation of FEP. To do so, it draws on Worrall’s (Dialectica 43(1–2): 99–124, 1989) proposal. The general insight of Worrall’s paper is that there is progress at the level of the structure of theories rather than their content. To enact Worrall’s strategy in the context of FEP, this paper will focus on characterising the formal continuity between fundamental equations of (...) thermodynamics—such as Boltzmann’s equation and Gibbs’s equation—on the one hand, and Friston’s characterisation of FEP on the other. Lack of a universal consensus on the physical character of entities that feature in thermodynamics, information theory and FEP notwithstanding, I argue that there is structural continuity and unity at the level of mathematical equations that regiment entropy, information and free energy. The existence of such structural continuity and unity provides grounds for structural realism about FEP. (shrink)

Our best social scientific theories try to tell us something about the social world. But is talk of a “social world” a metaphor that we ought not take too seriously? In particular, do the denizens of the social world—cultural values like the Protestant work ethic, firms like ExxonMobil, norms like standards of dress and behavior, institutions like the legal system, teams like FC Barcelona, conventions like marriages—exist? The question is not merely academic. Social scientists use these different social entities (...) to explain social phenomena such as the rise of capitalism, the decline in oil prices, or the effect of unions on the sports labor market. But how could these explanations possibly work if social entities don’t exist? (shrink)

Must we appeal to the notion of knowledge, in the subjective sense typically discussed by epistemologists, in the philosophy of science? Many scientific realists appear to think so, in so far as they assert that we can achieve knowledge of unobservable things, and of theories concerning them. As a natural result, perhaps, this has recently led Bird to suggest that scientific progress should be understood in terms of knowledge, rather than merely truth. But I would instead suggest that making scientific (...) progress consists in acquiring useful information. I will argue for this by pointing out the scientific importance of collecting information that is not and will not ever be believed, is false, and is truly believed without being justifiably believed. I will also say something about the different ways that ‘useful’ may be understood, with special reference to the property of truth and its role in positions such as constructive empiricism and structural realism. My own view is that even fictions may be both useful and informative; and this gels nicely with some recent work, e.g. by Frigg, on scientific models. (shrink)

Preanalytically, we are all scientific realists. But both philosophers and scientists become uncomfortable when forced into analysis. In the case of scientists, this discomfort often arises from practical difficulties in setting out a carefully described set of objects which adequately account for the phenomena with which they are concerned. This paper offers a set of representative examples of these difficulties for contemporary physicists. These examples challenge the traditional realist vision of mature scientific activity as struggling toward an ontologically well-defined world (...) picture. They challenge antirealist alternatives as well. (shrink)

The realism/antirealism controversy has gone on for centuries, and gives every indication that it will continue to go on for centuries. Dismayed, I take a closer look at it. I find that the question it poses--very roughly, whether scientific knowledge is true (approximately true, put forward as true, etc.) or only useful (empirically adequate, a convenient method of representation, etc.)--actually suppresses socially critical thought and discussion about science (e.g., concerning whether scientific knowledge is sexist or racist or (...) socially harmful in other ways, or whether scientific knowledge is useful for achieving the goals we have or the goals we ought to have). I find, as well, that two of the most important responses to the realism/antirealism controversy--that which construes it as concerned with science's aims and that which construes it as concerned with science's results--fail to make sufficient empirical or normative contact with science. As a consequence, they provide representations of science that either do not help scientists (or nonscientists) make informed decisions about science, or actually hinder these individuals from doing so. I conclude that we should either stop engaging in the realism/antirealism controversy entirely, or else engage in it in a more socially responsible way--by gathering the right kinds of empirical and normative data, and framing more helpful versions of the questions we want to ask. I end by responding to the strong objections sure to be voiced by my colleagues in philosophy of science. (shrink)

The current state of philosophy of science is characterized by stasis in the struggle between realism and antirealism. In recent years, a number of authors have come out with a program of scientific perspectivism that claims to sublate this great collision and gain the status of a new epistemological paradigm: “perspectivism, or, better, perspectival realism, is one of the newest attempts to find a middle ground between scientific realism and antirealism” [1. P. 2]. Important milestones (...) of the perspective movement were the works of Ronald Giere, Francois Recanati, Bas van Fraassen, Michela Massimi, and others. The thesis of the article is that perspectivism has not yet realized its claims to autonomy, although it has become an important new arena for discussions between realists and antirealists who try to appropriate perspectivist concepts and arguments. The “middle ground,” when thought out consistently and thoroughly, turns out to lie not “between,” but either in the territory of realism or in the territory of antirealism, depending on the presumptions of the author of a particular perspectivist conception. This is demonstrated by the analysis of the conceptions of Giere, Massimi, and Recanati. Giere’s perspectivism is based on the metaphor of color vision, and for him only some (secondary) qualities of real objects turn out to be perspectival, i.e., subject-dependent. Massimi’s perspectivism attempts, on the basis of a visual arts metaphor, to combine the phenomenon of the plurality of scientific theories (“perspectival disagreement” about what an object is) with the general realist attitude of science (agreement about that there is an object). Recanati’s perspectivism syncretizes realism about ordinary objects and relativism about other things. The first two versions of perspectivism rely on a perceptual metaphor: perspective is conditioned by the perceptual constitution of the observer, that is, it arises at the mental or cognitive level. Recanati’s version attempts to derive perspective from contextuality, that is, it is semantic. However, it does not show exactly how perceptual categories are superimposed on theories or how scientific concepts reveal their perspectival character. The isomorphism of perception and theoretical thinking, sensibility and understanding, remains undemonstrated. On the one hand, perspectivist efforts are motivated by an important concern to account for antirealist critique (lack of access to the “view from nowhere,” factual and semantic underdetermination, difficulties with the idea of approaching the truth, the historicity of knowledge, the activeness of the constructing subject, etc.) while preserving the scientific commitment to universality, validity, and truthfulness. On the other hand, the ontological question remains fundamental and unavoidable, and perspectivism (yet?) fails to circumvent it. As we see, all three versions of perspectivism considered in this article turn out to be varieties of realism: Giere and Massimi recognize this explicitly, while Recanati de facto assumes a quite respectable and conservative position of selective realism with respect to ordinary objects.

This paper recapitulates my four primary lines of argument that what is wrong with scientific realism is not realist answers to questions to which various anti-realists give different answers, but instead assumptions shared by realists and anti-realists in framing the question. Each strategy incorporates its predecessors as a consequence. A first, minimalist challenge, taken over from Arthur Fine and Michael Williams, rejects the assumption that the sciences have a general aim or goal. A second consideration is that realists and (...) antirealists undertake a mistaken, substantive commitment to a separation between mind and world, which allows them to frame the issue in terms of how epistemic “access” to the world is mediated. A third strategy for dissolving the realism question challenges its underlying commitment to the independence of meaning and truth, a strategy pursued in different ways by Donald Davidson, Robert Brandom, John McDowell, John Haugeland, and myself. The fourth and most encompassing strategy shows that realists and antirealists are thereby committed to an objectionably antinaturalist conception of scientific understanding, in conflict with what the sciences themselves have to say about our own conceptual capacities.

The representation theorems of expected utility theory show that having certain types of preferences is both necessary and sufficient for being representable as having subjective probabilities. However, unless the expected utility framework is simply assumed, such preferences are also consistent with being representable as having degrees of belief that do not obey the laws of probability. This fact shows that being representable as having subjective probabilities is not necessarily the same as having subjective probabilities. Probabilism can be defended on the (...) basis of the representation theorems only if attributions of degrees of belief are understood either antirealistically or purely qualitatively, or if the representation theorems are supplemented by arguments based on other considerations (simplicity, consilience, and so on) that single out the representation of a person as having subjective probabilities as the only true representation of the mental state of any person whose preferences conform to the axioms of expected utility theory.

The label realist in the debate about natural kinds can imply different things. Many authors in this debate subscribe to views that are in some way realist, but without making clear whether the realism in question specifically attaches to kind categories or something else. The traditional understanding of realism about natural kinds is stated in terms of the mind-independence criterion. However, a recent tendency in the debate is to reject this understanding on the ground of its (...) incompatibility with naturalistic approaches to natural kinds. The aim of this paper is to disentangle different meanings attached to the term realism about natural kinds and examine arguments for rejecting the traditional mind-independence framing of the debate. I recommend the reestablishment of mind-independent realism as a legitimate contender for naturalist approaches to natural kinds by indicating that mind-independent realists have at their disposal all the resources to subscribe to such an approach. I proceed by showing how keeping the traditional distinction between realist and antirealist views in terms of mind-independence allows us to keep track of important distinctions between different accounts of natural kinds which are otherwise blurred. Then I examine the arguments against this traditional framing and conclude that they either (1) rest on a conflation between mind-independence of kinds versus entities belonging to kinds, or (2) unjustifiably presuppose that mind-independent realists do not have resources to uphold a naturalistic view of natural kinds.

I look at the distinction between between realist and antirealist views of the quantum state. I argue that this binary classification should be reconceived as a continuum of different views about which properties of the quantum state are representationally significant. What's more, the extreme cases -- all or none --- are simply absurd, and should be rejected by all parties. In other words, no sane person should advocate extreme realism or antirealism about the quantum state. And (...) if we focus on the reasonable views, it's no longer clear who counts as a realist, and who counts as an antirealist. Among those taking a more reasonable intermediate view, we find figures such as Bohr and Carnap -- in stark opposition to the stories we've been told. (shrink)

Certain realists about properties and relations identify them with universals. Furthermore, some hold that for a wide range of meaningful predicates, the semantic contribution to the propositions expressed by the sentences in which those predicates figure is the universal expressed by the predicate. I here address ontological issues raised by predicates first introduced to us via works of fiction and whether the universal realist should accept that any such predicates express universals. After assessing arguments by Braun, D. and (...) Sawyer, S. for fictional universal anti-realism, I propose a novel, Kripke-inspired argument for the same conclusion. I ultimately defend the claim that while this argument presents the strongest case for fictional universal anti-realism, it is nonetheless unsound. I conclude that nothing stands in the way of accepting that some fictional predicates express fictional universals. (shrink)

This paper argues that realism issue in the social sciences is not one that can be decided by general philosophical arguments that evaluate entire domains at once. The realism issue is instead many different empirical issues.

I favor. (shrink)

Putnam is famous for often changing his allegiance between various forms of realism and antirealism. In this paper I want to use Putnam’s own reflections and insights on the realism-antirealism issue to provide a powerful case for skepticism about the entire debate—in spite of the fact that that is not Putnam’s own ultimate attitude. From this skeptical perspective, I shall argue that Putnam has helped us see that the realism-antirealism debate faces a dilemma: (...) either it resolves into existence questions about particular items that are resolvable by, say, scientific or mathematical or ethical etc. practices rather than by appeal to philosophical argument; or it represents a misguided response to skepticism about an entire class or realm of items given that it hopelessly attempts to answer skepticism on the skeptic’s own terms. What Putnam tends to overlook in his realist moments is that we can philosophically undermine skepticism without being committed to any philosophically substantial realism or antirealism. (shrink)

On the Dummettian understanding, anti-realism regarding a particular discourse amounts to (or at the very least, involves) a refusal to accept the determinacy of the subject matter of that discourse and a corresponding refusal to assert at least some instances of excluded middle (which can be understood as expressing this determinacy of subject matter). In short: one is an anti-realist about a discourse if and only if one accepts intuitionistic logic as correct for that discourse. On careful examination, (...) the strongest Dummettian arguments for anti-realism of this sort fail to secure intuitionistic logic as the single, correct logic for anti-realist discourses. Instead, antirealists are placed in a situation where they fail to be justified in asserting monism (that intuitionistic logic is the unique correct logic). Thus, antirealists seem forced either to accept pluralism (i.e. one or more intermediate logic is at least as `correct’ as intuitionistic logic–an option I take to be unattractive from the anti-realist perspective), or they must be anti-realists about the realism/anti-realism debate (and, in particular, must refuse to assert the instance of excluded middle equivalent to logical monism or logical pluralism).

Failure to recognize the "realistic" motivations for Putnam's commitment to internal realism has led to a widely shared misunderstanding of Putnam's arguments against metaphysical realism. Realist critics of these arguments frequently offer rebuttals that fail to confront his arguments. Simply put, Putnam's arguments --the brains in a vat argument as well as the model-theoretic argument -- are "reductios" that are intended to show that "metaphysical realism itself is not sufficiently realistic". If that claim can be substantiated then (...) Putnam can go on to argue that his own view is, by comparison, more realistic than metaphysical realism. (shrink)

Nyāya realists drew an important distinction between absence and non-existence. Perished particulars, such as Aristotle, emperor Ashoka, or the Bamiyan Buddha statues in Afghanistan are absent now but they are not non-existent in the sense of having become unreal or fictional. By dying, my grandmother did not become nonexistent like Snow White, though she suffered post-cessation absence. In order to be really dead, one could aptly remark, she has to be real. Can we therefore be realists about now deceased (...) individuals or past event-entities or should we listen to Vasubandhu and adopt a subtle anti-realism about wholly past entities and events. Can both Michael Dummett and his death (in 2011) be deemed unreal now? Inspired by Buddhist philosophers from Nāgārjuna to Śāntarakṣita, Mark Siderits has been committed to a nuanced fictionalist version of anti-realism not only about universals, permanent selves, and the external world but even about consciousness. In this paper I try, first, to reconstruct such an anti-realism about the past using Vasubandhu’s critique of the omni-existentist (sarvāstivādin) early Buddhists, and then respond to it by bringing in Bhāsarvajña the Kashmir-Naiyāyika and Michael Dummett into dialogue with Vasubandhu and his realist Buddhist predecessors.

Realism about affirmations of a given type is the view that these affirmations are to be understood as assertions that attempt to describe a largely independent reality, and that they are correct if and only if they manage to do so (regardless of whether they can be known to be correct). Objectivisim about affirmations of a given type is the view that they are subject to adequate, non-arbitrary standards of correctness, and that there are a significant number (...) of non-trivial affirmations of this type that can be known to be correct. On this understanding, realism, objectivism, and their denials can be combined in four possible ways: realism with objectivism, realism with antiobjectivism, antirealism with objectivism, and antirealism with antiobjectivism. This paper clarifies the distinction between realism and objectivism, illustrates it applications in various fields of philosophy, and draws attention to its value. (shrink)

Despite protestations to the contrary, philosophers have always been renowned for espousing theories that do violence to common-sense opinion. In the last twenty years or so there has been a growing number of philosophers keen to follow in this tradition. According to these philosophers, if a story of pure fic-tion tells us that an individual exists, then there really is such an individual. According to these realists about fictional characters, ‘Scarlett O’Hara,’ ‘Char-lie Brown,’ ‘Batman,’ ‘Superman,’ ‘Tweedledum’ and ‘Tweedledee’ are (...) not denotationless terms, but names that really refer. What is truly surprising about this situation is that almost no one has inveighed against this unfortunate real-ist tendency. My aim here will be to challenge this new orthodoxy, and to defend an anti-realist position against the arguments proffered by the realist. (shrink)

Upholders of fictionalism about scientific models have not yet successfully explained how scientists can learn about the real world by making comparisons between models and the real phenomena they stand for. In this paper I develop an account of model-world comparisons in terms of what I take to be the best antirealist analyses of comparative claims that emerge from the current debate on fiction.

Many participants in the debate over the current state and recent developments of economics make claims that are unrefined, simplistic, often exaggerated. This is understandable: the stakes are high, the issues trigger emotional responses, and few participants are motivated or equipped to seek more nuanced analyses. To assert, or to deny, that economics as a scientific discipline or a particular part of it (such as a model) is about reality – or refers to reality, represents it, is true (...) class='Hi'>about it, or is truthlike about it – is to make a very complex and highly ambiguous claim. 1 The disputants often make claims that have parallels in the philosophical controversy between scientific realists and their opponents, or at any rate those claims can be partly analyzed in terms of some of the arguments presented in this philosophical controversy. The question addressed here is whether realism about economics is a viable position. The argument proceeds by way of refuting a number of arguments against realism about economics. I suggest a genuine controversy over the factuality of any particular strand or piece of economics requires realism as a general interpretation of economics – or at any rate requires debunking the anti-realist arguments discussed below. “The issue of realism” as most economists would recognize it, is not exactly the issue of realism as philosophers recognize it. “The issue of realism” in economics is about realisticness as a property of theories , while (part of) the issue of realism in philosophy is about realism as a theory of theories . But some parts of the issue of realisticness (such as those related to reference and truth) in economics can be translated into aspects of the issue of realism as a theory of theories. Thus there is also an issue of realism (with no quotation marks) in economics. It is this issue of realism that has to be settled as a prerequisite for critical assessments of important forms of realisticness of economic theories. (shrink)

Mathematics is one of the many domains where the adoption of a form of realism has traditionally been challenged. Behaviorism and phenomenalism, opposed to realism about, respectively, mental entities and the existence of material objects, are other well‐known examples. The realism debate, as initiated by Dummett's challenge, appears to have run its course, at least on its original terms, and difficulties have been raised with respect to both antirealist and anti‐antirealist readings of Wittgenstein within that debate. (...) Realism about meaning did not remain unchallenged, however, as successor debates took its place, surrounding Robert Brandom's “inferentialism” or Price's generalized form of quasi‐realism, called “pragmatism”. Brandom also espouses “non‐representationalism” and predictably made use of Wittgenstein, with a reading akin to Kripke's of the rule‐following argument. He was criticized by McDowell largely for failing to account for Wittgenstein's quietism. (shrink)

Individual realism asserts that our best scientific theories are (approximately) true. In contrast, selective realism asserts that only the stable posits of our best scientific theories are true. Hence, individual realism recommends that we accept more of what our best scientific theories say about the world than selective realism does. The more scientists believe what their theories say about the world, the more they are motivated to exercise their imaginations and think up new theories (...) and experiments. Therefore, individual realism better fosters scientific creativity than selective realism. (shrink)

This paper supports the thesis that nihilistic interpretations of Madhyamaka philosophy derive from generally antirealistic and/or metaphysical approaches to Nāgārjuna’s thought. However, the arguments and many images by way of which the author of the Mūlamadhyamakakārikā and his Indian commentators defend themselves from the charge of nihilism show limits in these approaches, and rather confirm that Nāgārjuna’s philosophy should be read as a theoretical proposal that is at once realistic and antimetaphysical. The epistemology inherent to the soteriological dimension of the (...) Buddha’s teaching, of which Nāgārjuna presents himself as a faithful continuer, assesses on the one hand the accomplishment of a ‘cognitive revolution’ consisting in the achievement of a new vision of reality and on the other the avoidance of any metaphysical description of the same vision. Comprehension of the Madhyamaka philosophical enterprise through a realistic-antimetaphysical lens seems to hinder and prevent the possibility of any nihilistic interpretation of Nāgārjuna. (shrink)

Realists about science tend to hold that our scientific theories aim for the truth, that our successful theories are at least partly true, and that the entities referred to by the theoretical terms of these theories exist. Antirealists about science deny one or more of these claims. A sizable minority of philosophers of science prefers not to take sides: they believe the realism debate to be fundamentally mistaken and seek to abstain from it altogether. In analogy with (...) other realism debates I will call these philosophers quietists. In the philosophy of science quietism often takes a somewhat peculiar form, which I will call naturalistic quietism. In this paper I will characterize Maddy’s Second Philosophy as a form of naturalistic quietism, and show what the costs for making it feasible are. (shrink)

It is often assumed that chemistry was a typical positivistic science as long as chemists used atomic and molecular models as mere fictions and denied any concern with their real existence. Even when they use notions such as molecular orbitals chemists do not reify them and often claim that they are mere models or instrumental artefacts. However a glimpse on the history of chemistry in the longue durée suggests that such denials of the ontological status of chemical entities do not (...) testify for any specific allegiance of chemists to positivism. Rather it suggests that the dilemma positivism vs realism is inappropriate for characterizing the ontology of chemistry. This alternative shaped at the turn of the twentieth century in the context of controversies about atomic physics does not take into account the major concern of chemists, i.e. making up things. Only by considering what matters for chemists, their matters of concern rather than their matter theories, can we expect to get an insight on their ontological assumptions. The argumentation based on historical data is twofold. Generating new substances out of initial ingredients which is the raison d’être of chemistry raised a vexing puzzle which has been alternatively solved with the Aristotelian notion of mixt and the Lavoisieran notion of compound. I will argue that an essential tension remains intrinsic in chemistry between the two conceptual frameworks. But how are we to make sense of the long tradition of ontological non-commitment in chemistry? I argue that what is usually considered as a denial of the existence of the basic units of matter is better characterized as a focus on more important actors on the chemical stage. (shrink)

Anti-realists about the past claim that no one has yet manifested a knowledge of the truth of tensed instances of the realist schema '‡,' instances such as '‡. It is true that we cannot decide specific instances of the realist schema and that, consequently, neither our understanding of these instances, nor our knowledge of their truth may be constituted by the recognitional and executive capacities which, according to Michael Dummett's antirealism, constitute grasp of meaning. Although we cannot decide (...) these issues, we can meet Dummett's anti-realist's manifestability challenge by arguing for them from contingency. While no recognitional and decisional skills may constitute our knowledge that their truth-conditions are satisfied, we can, without begging the question, derive that knowledge from our folk and scientific theories of the workings of nature. The evidence we have in favor of the fact that evidential relations between us and past facts are naturally contingent allows us to infer tensed instances of the fundamental realist modal claim. The joint possibility of truth and undecideability pro tempora is a natural possibility and, thereby, a logical and metaphysical possibility. (shrink)

The modal antirealist, as presented here, aims to secure at least some of the benefits associated with talking in genuine modal realist terms while avoiding commitment to a plurality of Lewisian (or ersatz) worlds. The antirealist stance of agnosticism about other worlds combines acceptance of Lewis's account of what world-talk means with refusal to assert, or believe in, the existence of other worlds. Agnosticism about other worlds does not entail a comprehensive agnosticism about modality, but where such (...) agnosticism about modality is enforced, the aim of the agnostic programme is to show that it is not detrimental to our modal practices. The agnostic programme consists in an attempt to demonstrate the rational dispensability of that disputed class of modal beliefs which the agnostic eschews, but which are held by the realist and the folk. Here I attempt to motivate, describe, and illustrate such an agnostic antirealist programme in modal philosophy. (shrink)

Nathan Salmon has defended what might be called “weak modal anti-realism”—the view that possible-object names can refer to possible objects that neither exist nor are otherwise real. But rather than adopting a similar view in the fictional case, he instead defends fictional creationism—the view that fictional characters are existent but abstract entities created by authors of fiction. In this paper, I first argue that if weak modal antirealism is defensible then weak fictional antirealism is defensible as (...) well. Second, I argue that there is no reason to prefer fictional creationism over weak fictional antirealism but there is very good reason to prefer the latter over the former. And third, I defend weak fictional antirealism against the charge that it cannot provide a satisfactory account of statements that prima facie involve reference to or quantification over fictional characters.
