There is an uneasy tension between our ordinary talk about beliefs and desires and the ontological facts supported by neuroscience. Arguments for eliminative materialism can be fairly persuasive, yet error theory about folk psychological discourse may be unacceptable. One solution is to accept mental fictionalism: the view that we are (or should be) fictionalists about mentality. My aim in this paper is to explore mental fictionalism as a viable theoretical option, and to show that it has advantages over (...) other fictionalist views in the literature, as well as advantages over other theories of mind. However, mental fictionalism faces particular objections that do not plague other fictionalist accounts, nor other theories of the mind. These objections may provide some explanation as to why mental fictionalism has not (until recently) gained much traction in the literature. I end with some suggestions on how the mental fictionalist can address these objections, hopefully paving the way for further development of mental fictionalism as a live philosophical position in philosophy of mind. -/- .

Fictionalism is the view that a serious intellectual inquiry need not aim at truth. It came to prominence in philosophy in 1980, when Hartry Field argued that mathematics does not have to be true to be good, and Bas van Fraassen argued that the aim of science is not truth but empirical adequacy. Both suggested that the acceptance of a mathematical or scientific theory need not involve belief in its content. Thus the distinctive commitment of fictionalism is that (...) acceptance in a given domain of inquiry need not be truth-normed, and that the acceptance of a sentence from the associated region of discourse need not involve belief in its content. In metaphysics fictionalism is now widely regarded as an option worthy of serious consideration. This volume represents a major benchmark in the debate: it brings together an impressive international team of contributors, whose essays represent the state of the art in various areas of metaphysical controversy, relating to language, mathematics, modality, truth, belief, ontology, and morality.

In this book, Bradley Armour-Garb and James A. Woodbridge distinguish various species of fictionalism, locating and defending their own version of philosophical fictionalism. Addressing semantic and philosophical puzzles that arise from ordinary language, they consider such issues as the problem of non-being, plural identity claims, mental-attitude ascriptions, meaning attributions, and truth-talk. They consider 'deflationism about truth', explaining why deflationists should be fictionalists, and show how their philosophical fictionalist account of truth-talk underwrites a dissolution of the Liar Paradox and (...) its kin. They further explore the semantic notions of reference and predicate-satisfaction, showing how philosophical fictionalism can also resolve puzzles that these notions appear to present. Their critical examination of fictionalist approaches in philosophy, together with the development and application of their own brand of philosophical fictionalism, will be of great interest to scholars and upper-level students of philosophy of language, metaphysics, philosophical logic, philosophy of mind, epistemology, and linguistics.

Causation appears to present us with an interpretative difficulty. While arguably a redundant relation given fundamental physics, it is nevertheless apparently pragmatically indispensable. This chapter revisits certain arguments made previously by the author for these claims with the benefit of hindsight, starting with the role of causal models in the human sciences, and attempting to explain why it is not possible to straightforwardly ground such models in fundamental physics. This suggests that further constraints, going beyond physics, are needed to legitimate (...) such models. These supplementary constraints could be reified, but that would seem to conflict with the completeness of physics. A response is to emphasize the practical role of causal talk, and the author suggests that a fictionalist approach might be worth exploring. After clarifying fictionalism as a general approach, they carry out in some detail the project of clarifying what a fictionalist attitude to causation would involve. (shrink)

Mental fictionalism is the view that, even if mental states do not exist, it is useful to talk as if they do. Mental states are useful fictions. Recent philosophy of mind has seen a growing interest in mental fictionalism. To date, much of the discussion has concerned the general features of the approach. In this paper, I develop a specific form of mental fictionalism by drawing on Kendall Walton’s work on make-believe. According to the approach I propose, (...) talk of mental states is a useful pretence for describing people and their behaviour. I try to clarify and motivate this approach by comparing it to well-known alternatives, including behaviourism, instrumentalism and eliminativism. I also consider some of the challenges that it faces. (shrink)

Fictionalism plays a significant role in philosophy today, with defenses spanning mathematics, morality, ordinary objects, truth, modality, and more.1 Fictionalism in the philosophy of science is also gaining attention, due in particular to the revival of Hans Vaihinger’s work from the early twentieth century and to heightened interest in idealization in scientific practice.2 Vaihinger maintains that there is a ubiquity of fictions in science and, among other things, argues that Nietzsche supports the position. Yet, while contemporary commentators have (...) focused on fictionalism in Nietzsche’s moral philosophy, his view of fictions in science has remained largely unexamined.3 In this article, I begin...

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)

Modal fictionalists propose to defuse the unwanted ontological commitments of modal realism by treating modal realism as a fictional story, and modal assertions as assertions, prefixed by a fictionalist operator, that something is true in that story. However, consideration of conditionals with modal antecedents raises the problem ofembedding, which shows that the simple prefixing strategy cannotsucceed. A compositional version of the fictionalist strategy isdeveloped and critiqued, and some general semantic morals aredrawn from the failures of both strategies.

Our paper consists of three parts. In the first part we explain the concept of mental fictionalism. In the second part, we present the various versions of fictionalism and their main sources of motivation.We do this because in the third part we argue that mental fictionalism, as opposed to other versions of fictionalism, is a highly undermotivated theory.

Identity claims often look nonsensical because they apparently declare distinct things to be identical. I argue that this appearance is not just an artefact of grammar. We should be fictionalists about such claims, seeing them against the background of speakers' pretense that their words secure reference to a plurality of objects that are then declared to be identical from within the pretense. I argue that it is the resulting interpretative tension – arising from the fact that two things can never (...) be identical – that allows us to understand the real point of such statements. This view also offers a new solution to Fege's puzzle of the informativeness of identity statements. (shrink)

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

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.

One major problem with moral discourse is that we tend treat moral utterances as if they represent propositions. But complex metaphysical problems arise when we try to describe the nature of the moral facts that correspond to these propositions. If moral facts do not exist, how can moralizers justify engagement in moral practice? One possibility is abolitionism; abandoning morality and growing out of our old habits. Another option that has been suggested is that morality be preserved as a useful fiction. (...) Moral fictionalists propose that moralizers come to understand their moral beliefs as fictive precommitments that are instrumentally valuable. In this essay, I argue that this type of instrumentalist justification does not allow moralizers to have genuinely moral reasons for acting in accordance with their precommitments. The legislative function of morality and the concept of moral personhood cannot be supported by metaethical theories that only provide instrumental reasons for adopting moral discourse. Ironically, this implies that an instrumentalist moral society would not be able to preserve as many useful moral concepts as would a non-instrumentalist moral society. Since the fictionalists’ own criterion demands that they endorse the most instrumentally valuable metaethical theory, they cannot persuasively argue that their own metaethical alternative is viable. Fictionalists should, I argue, prefer a non-instrumentalist theory that preserves more of the functions of moral discourse, such as quasi-realism. The argumentative strategy employed by fictionalists is therefore self-undermining. (shrink)

A fictionalist attitude towards an area of discourse encourages us to assent to certain sentences of that discourse without believing that they are true. Prima facie, this amounts to a suggestion that we should also assent to sentences of the form 'S but I don't believe that S'. Traditional versions of fictionalism have an answer to this challenge, but I argue that the answer is unavailable for a currently popular type of fictionalism. This is bad news for (...) class='Hi'>fictionalism in general because the currently popular variety is the one that deals best with the Quine-Putnam indispensability argument. (shrink)

Mathematical fictionalism is the view according to which mathematical objects are ultimately fictions, and, thus, need not be taken to exist. This includes fictional objects, whose existence is typically not assumed to be the case. There are different versions of this view, depending on the status of fictions and on how they are connected to the world. In this paper, I critically examine the various kinds of fictionalism that Roberto Torretti identifies, determining to what extent they provide independent, (...) defensible conceptions of mathematical ontology and how they differ from platonism (the view according to which mathematical objects and structures exist and are abstract, that is, they are neither causally active nor are located in spacetime). I then contrast Torretti’s forms of fictionalism with a version of the view that, I argue, is clearly non-platonist and provides a deflationary account of mathematical ontology, while still accommodating the attractive features of the view that Torretti identified.

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)

The main task of this paper is to defend anti-platonism by providing an anti-platonist (in particular, a fictionalist) account of the indispensable applications of mathematics to empirical science.

According to non-doxastic theories of propositional faith, belief that p is not necessary for faith that p. Rather, propositional faith merely requires a ‘positive cognitive attitude’. This broad condition, however, can be satisfied by several pragmatic approaches to a domain, including fictionalism. This paper shows precisely how fictionalists can have faith given non-doxastic theory, and explains why this is problematic. It then explores one means of separating the two theories, in virtue of the fact that the truth of the (...) propositions in a discourse is of little consequence for fictionalists, whereas their truth matters deeply for the faithful. Although promising, this approach incurs several theoretical costs, hence providing a compelling reason to favour a purely doxastic account of faith. (shrink)

Modal fictionalists face a problem that arises due to their possible-world story being incomplete in the sense that certain relevant claims are neither true nor false according to it. It has recently been suggested that this incompleteness problem generalises to other brands of fictionalism, such as fictionalism about composite or mathematical objects. In this paper, I argue that these fictionalist positions are particularly threatened by a generalised incompleteness problem since they cannot emulate the modal fictionalists’ most attractive response. (...) I then defend mathematical and compositional fictionalism by showing that the reasons for which the incompleteness problem has been thought to affect them are mistaken. This leads to the question of whether there are other fictionalist positions to which the problem does in fact generalise. I give a general account of the features of a fictionalist position that generate the incompleteness problem and argue that whenever a fictionalist position does exemplify these features then the problem can be addressed in analogy to the modal fictionalists’ preferred response.

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)

Fictionalism confronts the dual epistemological nature of education. In this book, Johan Dahlbeck argues that all education, at bottom, concerns a striving for truth initiated through fictions. This foundational aporia is then interrogated and made sense of via Hans Vaihinger’s philosophy of ‘as if’ and Spinoza’s peculiar form of exemplarism. Using a variety of fictional examples, Dahlbeck investigates the different dimensions of educational fictionalism, from teacher exemplarism to the basic educational fictions necessary for getting started in education in (...) the first place. Fictionalism will be a valuable resource for anyone interested in the philosophical foundations of education. (shrink)

In this paper, I place Mary Leng’s version of mathematical instrumentalism within the context of the debate in mathematical realism/anti-realism as well as within the context of the platonism/nominalism debate. I maintain that although her position is able to show how the conjunction of Quinean naturalism and confirmational holism does not necessarily lead to the conclusion that mathematical objects must necessarily exist for they are indispensable in our best scientific theories; her usage of both theses still leads to platonism. Such (...) is the case for her characterization of scientific theories as akin to a set-theory that accommodates fictitious objects and statements within it is untenable due to the dependence of fictions on a realist ontology.

Although this article focuses on the consequences for a particular kind of religious fictionalist, the lessons adduced are intended to (...) have more general application. (shrink)

This book provides a coherent and systematic analysis of Miguel de Unamuno’s notion of religious faith and the reasoning he offers in defense of it. Unamuno developed a non-cognitivist Christian conception of religious faith, defending it as being something which we are all naturally lead to, given our (alleged) most basic and natural inclination to seek an endless existence. Illuminating the philosophical relevance this conception still has to contemporary philosophy of religion, Oya draws connections with current non-cognitivist notions of religious (...) faith in general, and with contemporary religious fictionalist positions more particularly. -/- The book includes a biographical introduction to Miguel de Unamuno, as well as lucid and clear analyses of his notions of the ‘tragic feeling of life’, his epistemological paradigm, and his naturally founded religious fictionalism. Revealing links to current debates, Oya shows how the works of Unamuno are still relevant and enriching today. (shrink)

The fictionalist paradigm is introduced, and differentiated from other paradigms, using the Lincoln & Guba template. Following an initial overview, the axioms of fictionalism are delineated by reference to standard metaphysical categories: the nature of reality, the relationship between knower and known, the possibility of generalization, the possibility of causal linkages, and the role of values in inquiry. Although a paradigm's ‘basic beliefs’ are arbitrary and can be assumed for any reason, in this paper the fictionalist axioms are supported (...) with philosophical considerations, and the key differences between fictionalism, positivism, and constructivism are briefly explained. Paradigm characteristics are then derived, focusing particularly on the methodological consequences. Towards the end of the paper, various objections and misunderstandings are discussed. (shrink)

Putnam rejects having argued in the terms of the argument known in the literature as “the Quine-Putnam indispensability argument”. He considers that mathematics contribution to physics does not have to be interpreted in platonist terms but in his favorite modal variety. The purpose of this paper is to consider Putnam’s acknowledged argument and philosophical position against contemporary so called in the literature ‘fictionalist’ views about applied mathematics. The conclusion will be that the account of the applicability of mathematics that stems (...) from Putnam‘s acknowledged argument can be assimilated to so-called ‘fictionalist’ views about applied mathematics.

According to a simple formulation of doxasticism about propositional faith, necessarily faith that p requires belief that p. Support of doxasticism is long-standing and was rarely a matter of dispute until William Alston (1996) proposed that that the content of propositional faith need not be believed if it is accepted. Subsequently non-doxastic theories that reject the belief requirement have proliferated and have come to dominate literature in the field. This paper aims to redress the balance by identifying a dilemma for (...) non-doxasticism that comes into view when we draw out the implications of non-doxasticism for the interpretation of affirmations of religious propositional faith. One horn of this dilemma commits non-doxasticists to hermeneutic fictionalism: a substantive, contentious and little explored theory about religious discourse. The other appears to render the affirmation of faith prima facie bullshitting, leading to problems about the integrity of religious discourse and its speakers. (shrink)

Universals are putative objects like wisdom, morality, redness, etc. Although we believe in properties (which, we argue, are not a kind of object), we do not believe in universals. However, a number of ordinary, natural language constructions seem to commit us to their existence. In this paper, we provide a fictionalist theory of universals, which allows us to speak as if universals existed, whilst denying that any really do.

Fictionalists maintain that possible worlds, numbers or composite objects exist only according to theories which are useful but false. Hale, Divers and Woodward have provided arguments which threaten to show that fictionalists must be prepared to regard the theories in question as contingently, rather than necessarily, false. If warranted, this conclusion would significantly limit the appeal of the fictionalist strategy rendering it unavailable to anyone antecedently convinced that mathematics and metaphysics concern non-contingent matters. I try to show that their arguments (...) can be resisted by developing and defending a strategy suggested by Rosen, Nolan and Dorr, according to which the fiction-operator is to be analysed in terms of a counterfactual that admits of non-trival truth-values even when the antecedent is impossible.

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)

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.

This paper develops and defends a revisionary fictionalist version of the ‘social connection model’ of responsibility. The social connection model has become a prominent account of responsibility in recent years but, as many critics have noted, has difficulty in providing an account of the connection required to generate responsibility which is sufficiently determinate and generates acceptable outcomes. In light of this problem, I first consider whether a fictionalist interpretation of Iris Marion Young’s articulation of the social connection model is tenable. (...) I show that no such re-interpretation is possible, as it runs against Young’s explicit aims. I then develop a more thoroughly revisionary fictionalist version of the social connection model. I argue that this form of responsibility fictionalism is able to account for the central aims of the social connection model without succumbing to the issues standard versions of the model face in grounding the attributions of responsibility it generates. Furthermore, I argue that attributions of responsibility can retain motivational force on this view. (shrink)

The Brock-Rosen problem has been one of the most thoroughly discussed objections to the modal fictionalism bruited in Gideon Rosen’s ‘Modal Fictionalism’. But there is a more fundamental problem with modal fictionalism, at least as it is normally explained: the position does not resolve the tension that motivated it. I argue that if we pay attention to a neglected aspect of modal fictionalism, we will see how to resolve this tension—and we will also find a persuasive (...) reply to the Brock-Rosen objection. Finally, I discuss an alternative reading of Rosen, and argue that this position is also able to fend off the Brock-Rosen objection. (shrink)

In ontology, realism and anti-realism may be taken as opposite attitudes towards entities of different kinds, so that one may turn out to be a realist with respect to certain entities, and an anti-realist with respect to others. In this book, the editors focus on this controversy concerning social entities in general and fictional entities in particular, the latter often being considered nowadays as kinds of social entities. More specifically, fictionalists (those who maintain that we only make-believe that there are (...) entities of a certain kind) and creationists (those who believe that entities of a certain kind are the products of human activity) present themselves as the champions of the anti-realist and the realist stance, respectively, regarding the above entities. By evaluating the pros and cons of both these positions, this book intends to focus new light on a longstanding debate. (shrink)

Religious fictionalism is the theory that it is morally and intellectually legitimate to affirm religious sentences and to engage in public and private religious practices, without believing the content of religious claims. This article discusses the main features of fictionalism, contrasts hermeneutic, and revolutionary kinds of fictionalism and explores possible historical and recent examples of religious fictionalism. Such examples are found in recent theories of faith, pragmatic approaches to religion, and mystical traditions in religious theology.

This paper explores a novel form of Mental Fictionalism: Fictionalism about talk of neural representations in cognitive science. This type of Fictionalism promises to (i) avoid the hard problem of naturalising representations, without (ii) incurring the high costs of eliminating useful representation talk. In this paper, I motivate and articulate this form of Fictionalism, and show that, despite its apparent advantages, it faces two serious objections. These objections are: (1) Fictionalism about talk of neural representations (...) ultimately does not avoid the problem of naturalising representations; (2) Fictional representations cannot play the explanatory role required by cognitive science.

Mark Eli Kalderon argues that morality is a fiction by means of which our emotional attitudes are conveyed. This is an improvement on the standard noncognitivist view, which denies that moral judgement is belief but claims instead that it is the expression of an emotional attitude. Noncognitivists tend to deny that moral sentences even purport to represent moral reality, and so they have developed non-standard semantics for moral discourse. Kalderon's fictionalism shows that noncognitivism can manage without such controversial semantics. (...) His book will be essential reading for anyone working in moral philosophy, and for many others working on meaning and knowledge. (shrink)

The aim of this chapter is to explain, motivate, and provide the central details of a specific version of what has come to be called alethic fictionalism—namely, a fictionalist account of truth (or, more accurately, of truth-talk, that fragment of discourse that involves the truth-predicate and other alethic-locutions). Our particular brand of alethic fictionalism is sometimes described as a “pretense theory of truth,” and a catchphrase for our view is “truth is a pretense.” But a more precise label (...) for the view that we will present is “semantic pretense-involving fictionalism about truth-talk.” Our endorsement of this view (for short, our SPIF account) stems from our belief that deflationism is the right approach to take on the topic of truth. This already shifts the focus away from any property of truth, since deflationism “about truth” (or, as we will call this view, T-deflationism) is best understood as an approach to analyzing truth-talk. We arrive specifically at our SPIF account of truth-talk because we also think that versions of T-deflationism should be understood as a kind of fictionalism (which, again, puts the focus on discourse, rather than metaphysics) and because we maintain that a SPIF account is the best variety of fictionalism to apply specifically to truth-talk. We will explain some of our reasons for holding these beliefs below, laying out the basics of our SPIF account of truth-talk and highlighting the merits of endorsing our particular account of that talk.

[Under contract with CUP, in preparation] What is a mind? Is it possible for a computer or other machine to have a mind? And how would we know? Mental fictionalism offers a new approach to these timely questions. Its central idea is that mental states (thoughts, beliefs, desires) are useful fictions. When we talk about mental states, we should be seen as merely speaking “as if” humans (and perhaps other creatures or even artifacts) had such states, in order to (...) make sense of their behavior. -/- This book is unique in presenting and defending three versions of mental fictionalism in a single volume (prefix-semantical mental fictionalism, pretense mental fictionalism, and affective storyism). The authors are three of the world’s most prominent proponents (respectively) of each variety: T. Parent (Nazarbayev University), Adam Toon (University of Exeter), and Tamás Demeter (Corvinus University of Budapest). The book essentially pits these different varieties of mental fictionalism against each other, allowing the reader to size them up. In the process, fresh perspectives are offered on foundational matters in the philosophy of mind, such as the nature of mental states and folk psychology, as well as hot topics such as embodied cognition, animal cognition, consciousness, and AI. -/- UPDATE: The chapter on prefix-semantical mental fictionalism is available upon request; write to nontology "at" gmail.

Prop oriented make-believe is make-believe utilized for the purpose of understanding what I call “props,” actual objects or states of affairs that make propositions “fictional,” true in the make-believe world. I, David Hills, and others have claimed that prop oriented make-believe lies at the heart of the functioning of many metaphors, and one variety of fictionalism in metaphysics invokes prop oriented make-believe to explain away apparent references to entities some find questionable or problematic (fictional characters, propositions, moral properties, numbers). (...) Elisabeth Camp has argued against my and David Hills’ views of metaphor. Her arguments, many of them echoed by Catharine Wearing, demolish a very implausible account of metaphor, but leave entirely untouched the views that Hills and I actually proposed. Clarifying what we say about metaphor serves also as a defense of fictionalist theories that invoke prop oriented make-believe. (shrink)

Mathematical fictionalism (or as I'll call it, fictionalism) is best thought of as a reaction to mathematical platonism. Platonism is the view that (a) there exist abstract mathematical objects (i.e., nonspatiotemporal mathematical objects), and (b) our mathematical sentences and theories provide true descriptions of such objects. So, for instance, on the platonist view, the sentence ‘3 is prime’ provides a straightforward description of a certain object—namely, the number 3—in much the same way that the sentence ‘Mars is red’ (...) provides a description of Mars. But whereas Mars is a physical object, the number 3 is (according to platonism) an abstract object. And abstract objects, platonists tell us, are wholly nonphysical, nonmental, nonspatial, nontemporal, and noncausal. Thus, on this view, the number 3 exists independently of us and our thinking, but it does not exist in space or time, it is not a physical or mental object, and it does not enter into causal relations with other objects. This view has been endorsed by Plato, Frege (1884, 1893-1903, 1919), Gödel (1964), and in some of their writings, Russell (1912) and Quine (1948, 1951), not to mention numerous more recent philosophers of mathematics, e.g., Putnam (1971), Parsons (1971), Steiner (1975), Resnik (1997), Shapiro (1997), Hale (1987), Wright (1983), Katz (1998), Zalta (1988), and Colyvan (2001).

Fictionalism is supposed to be motivated, at least in part, by its ability to undermine our ordinary grounds for believing in numbers and other contested entities. Eklund argues that a weaker and less controversial view, which he calls indifferentism, can do the job just as effectively. I will show that whether he’s right about this depends upon how we think about “our ordinary grounds”.
