I develop an account of predictive similarity that allows even Antirealists who accept a correspondence conception of truth to answer the Realist demand (recently given sophisticated reformulations by Musgrave and Leplin) to explain the success of particular scientific theories by appeal to some intrinsic feature of those theories (notwithstanding the failure of past efforts by van Fraassen, Fine, and Laudan). I conclude by arguing that we have no reason to find truth a better (i.e., more plausible) explanation of a theory's (...) success than predictive similarity, even of its success in making novel predictions.

Truth’s universal knowability entails its discovery. This threatens antirealism, which is thought to require it. Fortunately, antirealism is not committed to it. Avoiding it requires adoption (and extension) of Dag Prawitz’s position in his long-term disagreement with Michael Dummett on the notion of provability involved in intuitionism’s identification of it with truth. Antirealism (intuitionism generalized) must accommodate a notion of lost-opportunity truth (a kind of recognition-transcendent truth), and even truth consisting in the presence of unperformable verifications. Dummett’s (...) position cannot abide this, while Prawitz’s can. Antirealism’s epistemic notion of truth derives from general features of its meaning theory, not from a universal knowability principle. (shrink)

Debates between different kinds of scientific realists and antirealists are longstanding and show every sign of continuing. In this chapter I examine one explanation of their longevity: lurking beneath various forms of realism and antirealism are conflicting commitments which (1) sustain these positions and (2) are immune to refutation. These deeper commitments are to different epistemic stances. I consider the nature of philosophical stances generally and, more specifically, of epistemic stances in relation to the sciences. I investigate the question (...) of how stances are evaluated and adopted and elaborate on the most telling reason for their immunity, namely, a form of voluntarism regarding their adoption.

This landmark collection of essays by six renowned philosophers explores the implications of the contentious realism/antirealism debate for epistemology. The essays examine issues such as whether epistemology needs to be realist, the bearing of a realist conception of truth on epistemology, and realism and antirealism in terms of a pragmatist conception of epistemic justification. Richard Rorty's essay provides a critical commentary on the other five.

This paper contributes to the debate on the question of whether a systematic connection obtains between one’s commitment to realism or antirealism and one’s attitude towards the possibility of radical theoretical novelty, namely, theory change affecting our best, most successful theories (see, e.g., Stanford in Synthese 196:3915–3932, 2019; Dellsén in Stud Hist Philos Sci 76:30–38, 2019). We argue that it is not allegiance to realism or antirealism as such that primarily dictates one’s response to the possibility of radical (...) theoretical novelty: what matters the most is, rather, the proposed alternative’s promise to realize one’s favored cognitive aim(s). Our argument tells not only against Stanford’s account of how adherence to realism or antirealism orients how one responds to possible radical theoretical novelty, but also against what we call the “natural pairing thesis.” According to such a thesis, which has kept resurfacing in the history of the philosophy of science, one-to-one pairings obtain between realism/antirealism, on the one hand, and theoretical conservatism/openness to radical theoretical novelty, on the other hand. As our argument suggests, however, when faced with the possibility of radical theoretical novelty, realists can respond either in a conservative way or by being open to theory change, not unlike antirealists.

Nussbaum misconstrues the difference between Plato and Aristotle over what is real for a debate over a conception of truth. She seems to mistake Aristotle's arguments against Plato' version of realism as an argument against realism per se, though the texts do not permit such a reading. She claims Aristotle is convinced that realism involves a fatal “failure of reference,” yet she produces not a single text where Aristotle is even remotely concerned about such a failure of reference given the (...) commitments of realism. And nowhere is the crucial question of the relationship between Aristotle's antirealism and his method of appearances explicitly addressed or resolved.Nussbaum offers us a fashionable Aristotle. I have argued that, far from being attractive and obviously right on a deep and recent metaphysuical debate, Nussbaum's Aristotle is confused and inconsistent and thus that it is a good thing the texts do not support such a characterization.

Scientific antirealists run the argument from underconsideration against scientific realism. I argue that the argument from underconsideration backfires on antirealists’ positive philosophical theories, such as the contextual theory of explanation (van Fraassen, 1980), the English model of rationality (van Fraassen, 1989), the evolutionary explanation of the success of science (Wray, 2008; 2012), and explanatory idealism (Khalifa, 2013). Antirealists strengthen the argument from underconsideration with the pessimistic induction against current scientific theories. In response, I construct a pessimistic induction against antirealists that (...) since antirealists generated problematic philosophical theories in the past, they must be generating problematic philosophical theories now.

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)

This project is an investigation into the prospects for an antirealist theory of essence. Essentialism is the claim that at least some things have some of their properties essentially. Essentialist discourse includes claims such as “Socrates is essentially human”, and “Socrates is accidentally bearded”. Historically, there are two ways of interpreting essentialist discourse. I call these positions ‘modal essentialism’ and ‘neo-Aristotelian essentialism’. According to modal essentialism, for Socrates to be essentially human is for it to be necessary that he be (...) a human if he exists, and for Socrates to accidentally have a beard is for it to be contingent that Socrates has a beard if he exists. According to neo-Aristotelian essentialism, objects have definitions in something like the way words do. For Socrates to be essentially human but accidentally bearded is for it to be part of the definition of Socrates that he is human, but not part of that definition that he is bearded. I argue that both are susceptible to antirealist interpretation. This thesis sets about showing that this is the case. In Chapters One and Two I investigate neo-conventionalist theories of modality, in the hope of using such a position to develop an antirealist modal essentialism. In Chapter Three I discuss the debate between modal and neo-Aristotelian essentialism and conclude that it is by no means settled. In Chapter Four I develop an antirealist neo-Aristotelian essentialism based on the mechanism of one of the neo-conventionalist accounts of modality. In Chapter Five I argue that this account is in a better position to give an essentialist theory of necessity than its realist counterparts. I conclude that, regardless of whether one is a modal or neo-Aristotelian essentialist, antirealist essentialism is a viable theory of essence that is worthy of consideration in contemporary debate.

Strictly intuitionistic inferences are employed to demonstrate that three conditions—the existence of Brouwerian weak counterexamples to _Test_, the recognition condition, and the _BHK_ interpretation of the logical signs—are together inconsistent. Therefore, if the logical signs in mathematical statements governed by the recognition condition are constructive in that they satisfy the clauses of the _BHK_, then every relevant instance of the classical principle _Test_ is true intuitionistically, and the antirealistic critique of conventional logic, once thought to yield such weak counterexamples, is (...) seen, in this instance, to fail.

According to semantic antirealism, intuitionistic logic satisfies the requirement that truth should be constrained by provability in principle. Some philosophers have argued that semantic antirealism must be committed to effective provability and that the commitment leads to a stronger kind of logical revisionism exemplified by substructural logics. I shall take into account two different kinds of reply. The first is concerned with meaning per se and grasp or fixing of meaning. It rests on the idea that if we (...) have a method which may be used over some surveyable range, we have determined a way of applying the method everywhere in principle, and that this is enough as far as fixing or grasping meaning is concerned. The second concerns two radical antirealist principles disqualifying structural rules: Token Preservation and Preservation of Local Feasibility. Against criticisms, I shall argue that conceptual support may be provided for both. The main point in this debate is that there is a decisive difference between the rejection of classical logic via the curbing of the epistemic idealizations embedded in structural rules and the rejection of classical logic via the intuitionistic criticism of invalid introduction and elimination rules. It will be explained why the second rejection is stronger than the former. (shrink)

The expression conditional fallacy identifies a family of arguments deemed to entail odd and false consequences for notions defined in terms of counterfactuals. The antirealist notion of truth is typically defined in terms of what a rational enquirer or a community of rational enquirers would believe if they were suitably informed. This notion is deemed to entail, via the conditional fallacy, odd and false propositions, for example that there necessarily exists a rational enquirer. If these consequences do indeed follow from (...) the antirealist notion of truth, alethic antirealism should probably be rejected. In this paper we analyse the conditional fallacy from a semantic (i.e. model-theoretic) point of view. This allows us to identify with precision the philosophical commitments that ground the validity of this type of argument. We show that the conditional fallacy arguments against alethic antirealism are valid only if controversial metaphysical assumptions are accepted. We suggest that the antirealist is not committed to the conditional fallacy because she is not committed to some of these assumptions. (shrink)

Antirealism about metaphysical explanation is relatively underexplored. This paper maps out the territory for the antirealist, explaining what it would take to be an antirealist given various different conceptions of metaphysical explanation, and of the relationship between metaphysical explanation and grounding.

In this important book, Drew Khlentzos explains the antirealist argument from a realist perspective. He defends naturalistic realism against the antirealist challenge, and he considers the consequences of his defense for our understanding of realism and truth. Khlentzos argues that the naturalistic realist view that the world exists independently of the mind must take into consideration what he calls the representation problem: if the naturalistic realist view is true, how can mental representation of the world be explained?He examines this major (...) antirealist challenge in detail and shows that many realists have dismissed it because they have not understood its nature. He sees it as a philosophical puzzle: the antirealist challenge, if sound, does not prove that there are no objects that exist independently of the mind, but that there is no rational basis for thinking that there are; we have good reason to believe in the naturalistic view, but we have no way of knowing how it could be true. Khlentzos surveys the antirealist arguments of Michael Dummett, Hilary Putnam, and Crispin Wright and suggests a realist answer. He argues for a radically nonepistemic conception of truth, and against pragmatist, intuitionist, verificationist, and pluralist alternatives. He examines and rejects some current versions of physicalism and functionalism, and offers an original version of the correspondence theory of truth. (shrink)

Scientific realists have argued that the truth(likeness) of our theories provides the only explanation for the success of science. I consider alternative explanations proposed by antirealists. I endorse Leplin's contention that neither van Fraassen's Darwinist explanation nor Laudan's methodological explanation provides the sort of explanatory alternative which is called for in this debate. Fine's suggestion--that the empirical adequacy of our theories already explains their success--is more promising for antirealists. Leplin claims that this putative explanation collapses into realism on one reading (...) and into vacuity on another reading. But his analysis conflates three doctrines into two, and one of the three avoids both realism and vacuity. (shrink)

In everyday speech we seem to refer to such things as abstract objects, moral properties, or propositional attitudes that have been the target of metaphysical and/or epistemological objections. Many philosophers, while endorsing scepticism about some of these entities, have not wished to charge ordinary speakers with fundamental error, or recommend that the discourse be revised or eliminated. To this end a number of non-revisionary antirealist strategies have been employed, including expressivism, reductionism and hermeneutic fictionalism. But each of these theories faces (...) forceful objections. In particular, we argue, proponents of these strategies face a dilemma: either concedes that their theory is revisionary, or adopt an implausible account of speaker-meaning whereby the content of certain types of utterance is opaque to their speakers. In this paper we introduce a new type of antirealist strategy, which is thoroughly non-revisionary, and leaves speaker-meaning transparent to speakers. We draw on work on pragmatics in the philosophy of language to develop a theory we call ‘pragmatic antirealism’. The pragmatic antirealist holds that while the sentences of the discourses in question have metaphysically contentious truth conditions, ordinary utterances of them are pragmatically modified in context in such a way that speakers do not incur commitment to those truth conditions. After setting out the theory, we show how it might be developed for both mathematical and ethical discourse, before responding to some likely objections. (shrink)

In an important article, Kim Sterelny and Philip Kitcher challenge the common assumption that for any biological phenomenon requiring a selectionist explanation, it is possible to identify a uniquely correct account of the relevant selection process. They argue that selection events can be modeled in any of a number of different, equally correct ways. They call their view ' Pluralism,' and explicitly connect it with various antirealist positions in the philosophy of science. I critically evaluate Sterelny and Kitcher's Pluralism along (...) with its attendant antirealist theses. In particular, I argue that there are serious problems with their pluralistic antirealism regarding units of selection. By correctly diagnosing these problems a more adequate position can be constructed. I defend such a position, which I designate Inclusive Hierarchical Monism, and show how it captures the important virtues of Sterelny and Kitcher's approach while avoiding its problems. (shrink)

Until now, antirealists have offered sketches of a theory of truth, at best. In this paper, we present a probabilist account of antirealist truth in some formal detail, and we assess its ability to deal with the problems that are standardly taken to beset antirealism.

Expressivism is the view that the function of normative sentences is not to represent a kind of fact, but to avow attitudes, prescribe behavior, or the like. The idea can be found in David Hume. In the 20th century, G.E. Moore’s Open Question Argument provided important support for the view. Elizabeth Anscombe introduced the notion of “direction of fit,” which helped distinguish expressivism from a kind of naive subjectivism. The central advantage of expressivism is that it easily explains the motivational (...) force of moral conviction. Its chief problem is it has difficulty explaining the “realist surface” of moralizing. Quasi-realism is a strategy for explaining the realist surface without abandoning the underlying ideas of expressivism. It aims to explain moral error as well as deal with the so-called Frege-Geach problem. This chapter explains quasi-realism, and evaluates it by comparison with its chief rivals: Aristotelian approaches, Kantian approaches, realist moral naturalism, and fictionalism. (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)

Brogaard and Salerno (2005, Nous, 39, 123–139) have argued that antirealism resting on a counterfactual analysis of truth is flawed because it commits a conditional fallacy by entailing the absurdity that there is necessarily an epistemic agent. Brogaard and Salerno's argument relies on a formal proof built upon the criticism of two parallel proofs given by Plantinga (1982, "Proceedings and Addresses of the American Philosophical Association", 56, 47–70) and Rea (2000, "Nous," 34, 291–301). If this argument were conclusive, (...) class='Hi'>antirealism resting on a counterfactual analysis of truth should probably be abandoned. I argue however that the antirealist is not committed to a controversial reading of counterfactuals presupposed in Brogaard and Salerno's proof, and that the antirealist can in principle adopt an alternative reading that makes this proof invalid. My conclusion is that no reductio of antirealism resting on a counterfactual analysis of truth has yet been provided. (shrink)

In this article, I make a novel argument for scientific antirealism. My argument is as follows: (1) the best human chess players would lose to the best computer chess programs; (2) if the best human chess players would lose to the best computer chess programs, then there is good reason to think that the best human chess players do not understand how to make winning moves; (3) if there is good reason to think that the best human chess players (...) do not understand how to make winning moves, then there is good reason to think that the best human theories about unobservables are wrong; therefore, (4) there is good reason to think that the best human theories about unobservables are wrong.

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)

In a nutshell, semantic antirealism is the doctrine that if a statement is true, then it must be possible, at least in principle, to determine that it is true. Consider the particular case of self-ascriptions of attitudes such as beliefs, desires and intentions, i.e. statements of the form "I φ [that] p", where φ ranges over propositional attitude verbs and p provides the content of whatever is φd by the self-ascriber. Should we be semantic antirealists about these when the (...) putative bearer of the attitude is the only individual who may retrieve a warrant in favour of his φing that p? We can't provide an answer to the question unless we're clear about (i) whether or not the "at least in principle" clause is too weak, and (ii) what the right construal of positive introspection should look like. 2 Thus two issues: strict finitism on the one hand and the phenomenological nature of introspective warrants on the other. I shall argue that recent views defended by Peacocke and Pryor are found wanting with respect to both. (shrink)

Throughout the past century, a debate has raged over the thesis of realism and its alternatives. In this volume of original essays, a group of philosophers explores the ongoing controversy.

A puzzle is generated by two intuitions about artworks: 1. There is no prima facie reason to take artworks to be mind-independent objects; 2. Aesthetic judgments are objective. These intuitions seem to be in tension, for if artworks or their aesthetic properties are mind-dependent, how can aesthetic judgments be objective? The common solution to the puzzle lies in rejecting or revising one of the two intuitions. Typically, realists reject 1, and many antirealists reject 2. I develop an antirealist aesthetic theory (...) that accommodates both intuitions, focusing on critical disagreement between epistemically optimal judges, realist difficulties with supervenience and response-dependence, the role of imagination in the experience of artworks, and the metaphorical quality of aesthetic discourse. The hallmark of realism, namely the mind-independence of aesthetic qualities, is an untenable commitment that yields an impoverished view of artworks. A cognitivist anti-realism is available which preserves the objectivity of aesthetic discourse and yields a richer conception of artworks and our interaction with them. (shrink)

In this paper, I re-examine Dummett's arguments against realism and, most notably, those against truth conditional semantics. Dummett claims that a (realist) truth conditional meaning theory will invariably encounter limitations when accounting for the meanings of the statements of the so-called "disputed class", and so must be rejected in favour of a theory of meaning couched in terms of proof or verification. The first part of this paper seeks to faithfully reconstruct Dummett's position on meaning. The subsequent parts are critical (...) of this position. In particular, I attempt to expose the shortcomings of an antirealist theory of meaning on the one hand, and then show how truth conditional semantics (be they realist or not) emerge relatively unscathed from Dummett's criticism on the other.

Many realists on kinds deem it highly controversial to consider artefact kinds real kinds on a par with natural ones. There is a built-in tendency in realism to conceive of artefact kinds as merely a conventional classification used for practical purposes. One can individuate three main different approaches characterizing real kinds and accordingly three different types of arguments against viewing artefact kinds as real kinds: the metaphysical, the epistemological and the semantic arguments. The aim of this contribution is to undermine (...) the thesis that it is possible to trace a clear distinction between artefacts and natural kinds in each of these approaches. As a consequence there are no metaphysical, epistemological and semantic bases for claiming that artefact kinds as opposed to natural ones are not real kinds. (shrink)

SummaryScientific realism is here made equivalent to the referentiality of scientific language. A clear distinction of meaning and reference is advocated and certain ‘symptoms' of referentiality in scientific language are stressed. It is then shown that contemporary scholars stressing the contextual determination of meaning, the meaning variance and theory‐ladenness of all terms in scientific theories, often fail to recognize that an independent ‘stable’ core of the meaning still exists. This allows for theory comparison and is witness that science investigates reality, (...) provided one is aware that different kinds of reality are investigated by different sciences. Naive realism amounts to disregarding that no access to reality is given outside meaning and language, naive antirealism amounts to overlooking that language refers to something different from language itself.

Although Kuhn is much more an antirealist than a realist, the earlier and later articulations of realist and antirealist ingredients in his views merit close scrutiny. What are the constituents of the real invariant World posited by Kuhn and its relation to the mutable paradigm-related worlds? Various proposed solutions to this problem (dubbed the "new-world problem" by Ian Hacking) are examined and shown to be unsatisfactory. In The Structure of Scientific Revolutions, the stable World can reasonably be taken to be (...) made up of ordinary perceived objects, whereas in Kuhn's later works the transparadigmatic World is identified with something akin to the Kantian world-in-itself. It is argued that both proposals are beset with insuperable difficulties which render Kuhn's earlier and later versions of antirealism implausible. (shrink)

Rachel Briggs’ critique of “antirealist” accounts of scientific law— including my own perspectivalist best-system account—is part of a project meant to show that Humean conceptions of scientific law are more problematic than has been commonly realized. Indeed, her argument provides a new challenge to the Humean, a thoroughly epistemic version of David Lewis’ “big, bad bug” for Humeanism. Still, I will argue, the antirealist (perspectivalist and expressivist) accounts she criticizes have the resources to withstand the challenge and come out stronger (...) for it. Attention to epistemic possibilities, I argue, shows a number of advantages to a perspectivalist account of scientific law. (shrink)
