Atheism is a familiar kind of skepticism about religion. Moral error theory is an analogous kind of skepticism about morality, though less well known outside academic circles. Both kinds of skeptic face a "what next?" question: If we have decided that the subject matter (religion/morality) is mistaken, then what should we do with this way of talking and thinking? The natural assumption is that we should abolish the mistaken topic, just as we previously eliminated talk of, say, bodily humors and (...) unicorns. The fictionalist, however, offers a less obvious recommendation. According to the fictionalist, engaging in the topic in question provides pragmatic benefits that do not depend on its truth-in a way roughly analogous to engaging with a novel or a movie. The religious fictionalist maintains that even if we were atheists, we should carry on talking, thinking, and acting as if religion were true. The moral fictionalist maintains a similar view regarding moral talk, thought, and action. Both forms of fictionalism face serious challenges. Some challenges can be levelled at either form of fictionalism (or at any form of fictionalism), whereas others are problems unique to moral fictionalism or to religious fictionalism. There are important questions to be asked about the relationship between these two kinds of fictionalism. Could moral fictionalism be plausible even if religious fictionalism is not (or vice versa)? This is a volume of thirteen previously unpublished papers on the topics of religious fictionalism, moral fictionalism, and the relation between these views. (shrink)

This book develops a new approach to the mind called mental fictionalism. The key idea behind this approach is that the mind is a useful fiction. The book begins with our ordinary conception of the mind (known as folk psychology). At present, the dominant interpretation of folk psychology sees it as an attempt to describe our inner machinery (a view the author calls Cartesianism). The representational theory of mind (or representationalism) argues that our folk theory is true, and that our (...) thoughts (especially our propositional attitudes, such as beliefs and desires) are representations inside our heads. Mental fictionalism offers a new interpretation of folk psychology. According to mental fictionalism, when we attribute beliefs and desires, we do not claim that people have representations inside their heads; we merely pretend that they do. Our ordinary conception of the mind is fundamentally metaphorical: we project the ‘outer world’ of human culture (especially language) onto the ‘inner world’ of the mind. This is an enormously useful way of making sense of people and their behaviour. But we should not forget that this inner world is only a fiction. (shrink)

This paper develops a proposal about the metaphysics of gender by focusing on the question, what is it to be a woman? In recent years, the view that it is a matter of self-identifying as a woman has become increasingly popular outside of philosophical circles. Metaphysicians of gender generally regard this kind of view as hopeless, but it is the only kind of view that accommodates the strongest form of first-person authority (FPA) over gender.This inquiry into the nature of gender (...) is an ameliorative one, which takes the aim of securing the strongest form of FPA as its starting point. The main goal of this paper is to show that a self-identification account of gender can be made philosophically respectable, despite conventional wisdom to the contrary—if we embrace fictionalism about gender discourse.In Section 1, I will outline the belief condition (a specific version of a self-identification account of gender), and detail several seemingly insurmountable objections to it. In Section 2, I will motivate the search for an account that accommodates the strongest form of FPA. In Section 3, I will outline fictionalism about gender discourse and explain how it can address the objections to the belief condition. In Section 4, I will flesh out some key details of gender fictionalism. In Section 5, I will outline and respond to a family of serious objections, to the effect that gender fictionalism trivializes gender. Section 6 briefly considers the question of whether we should do away with the “gender fiction”. (shrink)

A Critical Introduction to Fictionalism provides a clear and comprehensive understanding of an important alternative to realism. Drawing on questions from ethics, the philosophy of religion, art, mathematics, logic and science, this is a complete exploration of how fictionalism contrasts with other non-realist doctrines and motivates influential fictionalist treatments across a range of philosophical issues. Defending and criticizing influential as well as emerging fictionalist approaches, this accessible overview discuses physical objects, universals, God, moral properties, numbers and other fictional entities. Where (...) possible it draws general lessons about the conditions under which a fictionalist treatment of a class of items is plausible. Distinguishing fictionalism from other views about the existence of items, it explains the central features of this key metaphysical topic. Featuring an historical survey, definitions of key terms, characterisations of important subdivisions, objections and problems for fictionalism, and contemporary fictionalist treatments of several issues, A Critical Introduction to Fictionalism is a valuable resource for students of metaphysics as well as students of philosophical methodology. It is the only book of its kind. (shrink)

Fictional Discourse: A Radical Fictionalist Semantics combines the insight of linguistic and philosophical semantics with the study of fictional language. Its central idea is familiar to anyone exposed to the ways of narrative fiction, namely the notion of a fictional teller. Starting with premises having to do with fictional names such as 'Holmes' or 'Emma', Stefano Predelli develops Radical Fictionalism, a theory that is subsequently applied to central themes in the analysis of fiction. Among other things, he discusses the distinction (...) between storyworlds and narrative peripheries, the relationships between homodiegetic and heterodiegetic narrative, narrative time, unreliability, and closure. The final chapters extend Radical Fictionalism to critical discourse, as Predelli introduces the ideas of critical and biased retelling, and pauses on the relationships between Radical Fictionalism and talk about literary characters.

There are things we routinely say that may strike us as literally false but that we are nonetheless reluctant to give up. This might be something mundane, like the way we talk about the sun setting in the west, or it could be something much deeper, like engaging in talk that is ostensibly about numbers despite believing that numbers do not literally exist. Rather than regard such behaviour as self-defeating, a "fictionalist" is someone who thinks that this kind of discourse (...) is entirely appropriate, even helpful, so long as we treat what is said as a useful fiction, rather than as the sober truth. "Fictionalism" can be broadly understood as a view that uses a notion of pretense or fiction in order to resolve certain puzzles or problems that otherwise do not necessarily have anything to do with literature or fictional creations. Within contemporary analytic philosophy, fictionalism has been on the scene for well over a decade and has matured during that time, growing in popularity. There are now myriad competing views about fictionalism and consequently the discussion has branched out into many more subdisciplines of philosophy. Yet there is widespread disagreement on what philosophical fictionalism actually amounts to and about how precisely it ought to be pursued. This volume aims to guide these discussions, collecting some of the most up-to-date work on fictionalism and tracing the view's development over the past decade. After a detailed discussion in the book's introductory chapter of how philosophers should think of fictionalism and its connection to metaontology more generally, the remaining chapters provide readers with arguments for and against this view from leading scholars in the fields of epistemology, ethics, metaphysics, philosophy of science, philosophy of language, and others.

This paper explores a middle way between realism and eliminativism about grounding. Grounding-talk is intelligible and useful, but it fails to pick out grounding relations that exist or obtain in reality. Instead, grounding-talk allows us to convey facts about what metaphysically explains what, and about the worldly dependence relations that give rise to those explanations.

This paper discusses the nature of, problems for, and benefits delivered by fictionalist strategies in metaphysics.

Current debate in the metaphysics of time ordinarily assumes that we should be realists about time. Recently, however, a number of physicists and philosophers of physics have proposed that time will play no role in a completed theory of quantum gravity. This paper defends fictionalism about temporal thought, on the supposition that our world is timeless. We argue that, in the face of timeless physical theories, realism about temporal thought is unsustainable: some kind of anti-realism must be adopted. We go (...) on to provide an argument against eliminativism about temporal thought. While it doesn't follow from this argument that fictionalism about temporal thought is true, we suggest that this nonetheless shows that fictionalism should be regarded as the preferred view.

Science Without Numbers caused a stir in 1980, with its bold nominalist approach to the philosophy of mathematics and science. It has been unavailable for twenty years and is now reissued in a revised edition with a substantial new preface presenting the author's current views and responses to the issues raised in subsequent debate.

It is advisable to treat some sorts of discourse about fiction with the aid of an intensional operator "in such-And-Such fiction...." the operator may appear either explicitly or tacitly. It may be analyzed in terms of similarity of worlds, As follows: "in the fiction f, A" means that a is true in those of the worlds where f is told as known fact rather than fiction that differ least from our world, Or from the belief worlds of the community in (...) which the fiction originated.

In “On Sense and Reference,” surrounding his discussion of how we describe what people say and think, identity is Frege’s first stop and his last. We will follow Frege’s plan here, but we will stop also in the land of make-believe.

There is a widespread, popular view—and one I basically endorse—that Nietzsche is, in one sense of the word, a nihilist. As Arthur Danto put it some time ago, according to Nietzsche, “there is nothing in [the world] which might sensibly be supposed to have value.” As interpreters of Nietzsche, though, we cannot simply stop here. Nietzsche's higher men, Übermenschen, “genuine philosophers”, free spirits—the types Nietzsche wants to bring forth from the human, all-too-human herds he sees around him with the fish (...) hooks, as he says, of his books—seem to engage in what looks like valuing. These free spirits are supposed to revalue the old values—revaluing, as is clear from the texts, is not simply to remove the old values from circulation (Nietzsche uses “umwerten” and not “entwerten”)—and they are supposed to create new values. And, of course, Nietzsche himself, free spirit that he is, takes on the task of revaluing all values and seems to assert many a strident evaluation. So we need to say more here. What are Nietzsche and his free spirits up to when they engage in what looks, for all the world, like a practice of valuing? What is the practice of valuing Nietzsche is recommending for his free spirits? I argue for two claims: (i) First, we end up facing an interpretive puzzle when we attempt to explain how Nietzsche's free spirits are supposed to engage in a practice of valuing. (ii) Second, we can solve the interpretive puzzle by taking Nietzsche's free spirits to be engaged in a fictionalist simulacrum of valuing. (shrink)

In this book, Balaguer demonstrates that there are no good arguments for or against mathematical platonism. He does this by establishing that both platonism and anti-platonism are defensible views. Introducing a form of platonism ("full-blooded platonism") that solves all problems traditionally associated with the view, he proceeds to defend anti-platonism (in particular, mathematical fictionalism) against various attacks, most notably the Quine-Putnam indispensability attack. He concludes by arguing that it is not simply that we do not currently have any good argument (...) for or against platonism, but that we could never have such an argument and, indeed, that there is no fact of the matter as to whether platonism is correct.

In The Myth of Morality, Richard Joyce argues that moral discourse is hopelessly flawed. At the heart of ordinary moral judgements is a notion of moral inescapability, or practical authority, which, upon investigation, cannot be reasonably defended. Joyce argues that natural selection is to blame, in that it has provided us with a tendency to invest the world with values that it does not contain, and demands that it does not make. Should we therefore do away with morality, as we (...) did away with other faulty notions such as witches? Possibly not. We may be able to carry on with morality as a 'useful fiction' - allowing it to have a regulative influence on our lives and decisions, perhaps even playing a central role - while not committing ourselves to believing or asserting falsehoods, and thus not being subject to accusations of 'error'.

This new edition of Alexander Miller’s highly readable introduction to contemporary metaethics provides a critical overview of the main arguments and themes in twentieth- and twenty-first-century contemporary metaethics. Miller traces the development of contemporary debates in metaethics from their beginnings in the work of G. E. Moore up to the most recent arguments between naturalism and non-naturalism, cognitivism and non-cognitivism. From Moore’s attack on ethical naturalism, A. J. Ayer’s emotivism and Simon Blackburn’s quasi-realism to anti-realist and best opinion accounts of (...) moral truth and the non-reductionist naturalism of the ‘Cornell realists’, this book addresses all the key theories and ideas in this field. As well as revisiting the whole terrain with revised and updated guides to further reading, Miller also introduces major new sections on the revolutionary fictionalism of Richard Joyce and the hermeneutic fictionalism of Mark Kalderon. The new edition will continue to be essential reading for students, teachers and professional philosophers with an interest in contemporary metaethics. (shrink)

This is a concise, advanced introduction to current philosophical debates about truth. A blend of philosophical and technical material, the book is organized around, but not limited to, the tendency known as deflationism, according to which there is not much to say about the nature of truth. In clear language, Burgess and Burgess cover a wide range of issues, including the nature of truth, the status of truth-value gaps, the relationship between truth and meaning, relativism and pluralism about truth, and (...) semantic paradoxes from Alfred Tarski to Saul Kripke and beyond. Following a brief introduction that reviews the most influential traditional and contemporary theories of truth, short chapters cover Tarski, deflationism, indeterminacy, realism, antirealism, Kripke, and the possible insolubility of semantic paradoxes. The book provides a rich picture of contemporary philosophical theorizing about truth, one that will be essential reading for philosophy students as well as philosophers specializing in other areas.

In his contribution to this volume, Paul Bloomfield analyzes and attempts to answer the question “Why is it bad to be bad?” I too will use this question as my point of departure; in particular I want to approach the matter from the perspective of a moral error theorist. This discussion will preface one of the principal topics of this paper: the relationship between morality and self-interest. Again, my main goal is to clarify what the moral error theorist might say (...) on this subject. Against this background, the final portion of this paper will be a discussion of moral fictionalism, defending it from some objections. (shrink)

Region R Question: How many objects — entities, things — are contained in R? Ignore the empty space. Our question might better be put, 'How many material objects does R contain?' Let's stipulate that A, B and C are metaphysical atoms: absolutely simple entities with no parts whatsoever besides themselves. So you don't have to worry about counting a particle's top half and bottom half as different objects. Perhaps they are 'point-particles', with no length, width or breadth. Perhaps they are (...) extended in space without possessing spatial parts (if that is possible). Never mind. We stipulate that A, B and C are perfectly simple. We also stipulate that they are connected as follows. A and B are stuck together in such a way that when a force is applied to one of them, they move together 'as a unit'. Moreover, the two of them together exhibit behavior that neither would exhibit on its own — Perhaps they emit a certain sound, or glow in the dark — whereas C is.. (shrink)

Fictionalism has long presented an attractive alternative to both heavy-duty realist and simple eliminativist views about entities such as properties, propositions, numbers, and possible worlds. More recently, a different alternative to these traditional views has been gaining popularity: a form of deflationism that holds that trivial arguments may lead us from uncontroversial premisses to conclude that the relevant entities exist — but where commitment to the entities is a trivial consequence of other claims we accept, not a posit to explain (...) what makes the relevant claims true. The deflationist’s trivial arguments, however, have been attacked by fictionalists, who suggest that the ontological conclusions we get from these arguments should not be taken as serious ontological assertions at all, but rather as implicitly in the context of a fiction or simulation. This paper examines the fictionalist’s criticisms of ‘easy’ arguments for numbers, properties, and other entities, and concludes that they beg the question against the deflationist and so do not undermine the deflationist’s position. Close attention to the argument also reveals a crucial disanalogy between overtly fictional discourse and discourse about numbers, properties, and so on, which undermines the case for fictionalism. Finally, I argue that the motivations for fictionalism (particularly those based in its ability to offer a good account of the discourse) are served as well or better by deflationism. Overall, this gives us reason to think that deflationism may provide a preferable approach for those looking for an alternative to both traditional realism and traditional eliminativism. (shrink)

Fictionalism in ontology is a mixed bag. Here I focus on three main variants—which I label after the names of Pascal, Berkeley, and Hume—and consider their relative strengths and weaknesses. The first variant is just a version of the epistemic Wager, applied across the board. The second variant builds instead on the fact that ordinary language is not ontologically transparent; we speak with the vulgar, but deep down we think with the learned. Finally, on the Humean variant it’s the structure (...) of the ontological inventory, not its content, that may turn out to involve fictional elements. That is, for the Humean the fiction lies, not in the reality of common-sense ontology, but in the laws—of unity, identity, causation, etc.—in terms of which we articulate our experience of that reality. In the end, this is the kind of fictionalism that I find most interesting, sensible, and tenable. And I argue that it is even compatible with the sort of “naive” realism we have all come to appreciate in the work of Paolo Bozzi, to whom the paper is dedicated. (shrink)

[Stephen Yablo] The usual charge against Carnap's internal/external distinction is one of 'guilt by association with analytic/synthetic'. But it can be freed of this association, to become the distinction between statements made within make-believe games and those made outside them-or, rather, a special case of it with some claim to be called the metaphorical/literal distinction. Not even Quine considers figurative speech committal, so this turns the tables somewhat. To determine our ontological commitments, we have to ferret out all traces of (...) nonliterality in our assertions; if there is no sensible project of doing that, there is no sensible project of Quinean ontology. /// [Andre Gallois] I discuss Steve Yablo's defence of Carnap's distinction between internal and external questions. In the first section I set out what I take that distinction, as Carnap draws it, to be, and spell out a central motivation Carnap has for invoking it. In the second section I endorse, and augment, Yablo's response to Quine's arguments against Carnap. In the third section I say why Carnap's application of the distinction between internal and external questions runs into trouble. In the fourth section I spell out what I take to be Yablo's version of Carnap. In the last I say why that version is especially vulnerable to the objection raised in the second. (shrink)

Imaginative and creative capacities seem to be at the heart of both games of make-believe and figurative uses of language. But how exactly might cases of metaphor or idiom involve make-believe? In this paper, I argue against the pretense-based accounts of Walton (1990, 1993), Hills (1997), and Egan (this journal, 2008) that pretense plays no role in the interpretation of metaphor or idiom; instead, more general capacities for manipulating concepts (which are also called on within the use of pretense) do (...) the real explanatory work. This result has consequences for both our understanding of metaphor and idiom as well as for the use of figurative language by fictionalists in ontology. (shrink)

Philosophers and theorists have long been puzzled by humans' ability to talk about things that do not exist, or to talk about things that they think exist but, in fact, do not. _Empty Names, Fiction, and the Puzzles of Non-Existence_ is a collection of 13 new works concerning the semantic and metaphysical issues arising from empty names, non-existence, and the nature of fiction. The contributors include some of the most important researchers working in these fields. Some of the papers develop (...) and defend new positions on these matters, while others offer important new perspectives and criticisms of the existing approaches. The volume contains a comprehensive introductory essay by the editors, which provides a survey of the philosophical issues concerning empty names, the various responses to these issues, and the literature on the subject to date.

In this paper I outline an alternative to hermeneutic fictionalism, an alternative I call indifferentism, with the same advantages as hermeneutic fictionalism with respect to ontological issues but avoiding some of the problems that face fictionalism. The difference between indifferentism and fictionalism is this. The fictionalist about ordinary utterances of a sentence S holds, with more orthodox views, that the speaker in some sense commits herself to the truth of S. It is only that for the fictionalist this is truth (...) in the relevant fiction. According to the indifferentist, by contrast, we are simply non-committal – or indifferent – with respect to some aspects of what is literally said in our assertive utterances. (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)

Gideon Rosen’s [1990 Modal fictionalism. Mind, 99, 327–354] Modal Fictionalist aims to secure the benefits of realism about possible-worlds, whilst avoiding commitment to the existence of any world other than our own. Rosen [1993 A problem for fictionalism about possible worlds. Analysis, 53, 71–81] and Stuart Brock [1993 Modal fictionalism: A response to Rosen. Mind, 102, 147–150] both argue that fictionalism is self-defeating since the fictionalist is tacitly committed to the existence of a plurality of worlds. In this paper, I (...) develop a new strategy for the fictionalist to pursue in response to the Brock–Rosen objection. I begin by arguing that modal fictionalism is best understood as a paraphrase strategy that concerns the propositions that are expressed, in a given context, by modal sentences. I go on to argue that what is interesting about paraphrastic fictionalism is that it allows the fictionalist to accept that the sentence ‘there is a plurality of worlds’ is true without thereby committing her to the existence of a plurality of worlds. I then argue that the paraphrastic fictionalist can appeal to a form of semantic contextualism in order to communicate her status as an anti-realist. Finally, I generalise my conception of fictionalism and argue that Daniel Nolan and John O’Leary-Hawthorne [1996 Reflexive fictionalisms. Analysis, 56, 26–32] are wrong to suggest that the Brock-Rosen objection reveals a structural flaw with all species of fictionalism. (shrink)

Fictionalist approaches to ontology have been an accepted part of philosophical methodology for some time now. On a fictionalist view, engaging in discourse that involves apparent reference to a realm of problematic entities is best viewed as engaging in a pretense. Although in reality, the problematic entities do not exist, according to the pretense we engage in when using the discourse, they do exist. In the vocabulary of Burgess and Rosen (1997, p. 6), a nominalist construal of a given discourse (...) is revolutionary just in case it involves a “reconstruction or revision” of the original discourse. Revolutionary approaches are therefore prescriptive. In contrast, a nominalist construal of a given discourse is hermeneutic just in case it is a nominalist construal of a discourse that is put forth as a hypothesis about how the discourse is in fact used; that is, hermeneutic approaches are descriptive. I will adopt Burgess and Rosen’s terminology to describe the two different spirits in which a fictionalist hypothesis in ontology might be advanced. Revolutionary fictionalism would involve admitting that while the problematic discourse does in fact involve literal reference to nonexistent entities, we ought to use the discourse in such a way that the reference is simply within the pretense. The hermeneutic fictionalist, in contrast, reads fictionalism into our actual use of the problematic discourse. According to her, normal use of the problematic discourse involves a pretense. According to the pretense, and only according to the pretense, there exist the objects to which the discourse would commit its users, were no pretense involved. My purpose in this paper is to argue that hermeneutic fictionalism is not a viable strategy in ontology. My argument proceeds in two steps. First, I discuss in detail several problematic consequences of any interesting application of hermeneutic fictionalism. Of course, if there is good evidence that hermeneutic fictionalism is correct in some cases, then some of these drastic consequences would have to be accepted.. (shrink)

In this paper we introduce a distinct metaethical position, fictionalism about morality. We clarify and defend the position, showing that it is a way to save the 'moral phenomena' while agreeing that there is no genuine objective prescriptivity to be described by moral terms. In particular, we distinguish moral fictionalism from moral quasi-realism, and we show that fictionalism possesses the virtues of quasi-realism about morality, but avoids its vices.

This paper develops a novel version of anti-platonism, called semantic fictionalism. The view is a response to the platonist argument that we need to countenance propositions to account for the truth of sentences containing `that'-clause singular terms, e.g., sentences of the form `x believes that p' and `σ means that p'. Briefly, the view is that (a) platonists are right that `that'-clauses purport to refer to propositions, but (b) there are no such things as propositions, and hence, (c) `that'-clause-containing sentences (...) of the above sort are not true-they are useful fictions. Semantic fictionalism is an extension of Hartry Field's mathematical fictionalism, but my defense of the view is not analogous to his. One of the many virtues of my defense is its generality: it explains how we can adopt a fictionalist stance towards all abstract singular terms, e.g., mathematical singular terms and `that'-clauses.

According to the indispensability argument, the fact that we quantify over numbers, sets and functions in our best scientific theories gives us reason for believing that such objects exist. I examine a strategy to dispense with such quantification by simply replacing any given platonistic theory by the set of sentences in the nominalist vocabulary it logically entails. I argue that, as a strategy, this response fails: for there is no guarantee that the nominalist world that go beyond the set of (...) sentences in the nominalist language such theories entail. However, I argue that what such theories show is that mathematics can enable us to express possibilities about the concrete world that may not be expressible in nominalistically acceptable language. While I grant that this may make quantification over abstracta indispensable, I deny that such indispensability is a reason for accepting them into our ontology. I urge that the nominalist should be allowed to quantify over abstracta whilst denying their existence and I explain how this apparently contradictory practice (a practice I call 'weaseling') is in fact coherent, unproblematic and rational. Finally, I examine the view that platonistic theories are simpler or more attractive than their nominalistic reformulations, and thus that abstract ought to be accepted into our ontology for the same sorts of reasons as other theoretical objects. I argue that, at least in the case of numbers, functions and sets, such arguments misunderstand the kind of simplicity and attractiveness we seek. (shrink)

These days it is widely agreed that there is no such thing as absolute motion and rest; the motion of an object can only be characterized with respect to some chosen frame of reference.1 This is a fact of which many of us are well-aware, and yet a cursory consideration of the ways we ascribe motion to objects gives the impression that it is a fact we persistently ignore. We insist to the police officer that we came to a full (...) and complete stop at the stop sign, we fret that traffic is moving too slowly, we observe that the sun has dropped below the hills on the horizon, all without ever saying which frames of reference we have in mind.

It is not uncommon for philosophers to maintain that one is obliged to believe nothing beyond the observable consequences of a successful scientific theory. This doctrine is variously known as instrumentalism, fictionalism, constructive empiricism, theoretical skepticism and the philosophy of "as if". The purpose of the present paper is to subject such forms of scientific antirealism to a two-pronged critique. In the first place it is argued that there is no genuine difference between believing a theory and being disposed to (...) use it to make predictions, design experiments, and so on; so traditional instrumentalism is incoherent. In the second place, a retrenched position is considered in which theoretical belief would be tolerated but said to be justified on merely pragmatic, and not epistemic, grounds. In criticizing this point of view it is shown that the onus of proof rests on anyone who maintains it; furthermore, the only possible rationale for it (which is based on underdetermination of theory by data) is described, and various deficiencies in this argument are exposed.

This paper distinguishes revolutionary fictionalism from other forms of fictionalism and also from other philosophical views. The paper takes fictionalism about mathematical objects and fictionalism about scientific unobservables as illustrations. The paper evaluates arguments that purport to show that this form of fictionalism is incoherent on the grounds that there is no tenable distinction between believing a sentence and taking the fictionalist's distinctive attitude to that sentence. The argument that fictionalism about mathematics is ‘comically immodest’ is also evaluated. In place (...) of those arguments, an argument against fictionalism about abstract objects of any kind is presented in the last section. This argument takes the form of a trilemma against the fictionalist. (shrink)
