Ontological Fictionalism

Our ordinary moral practices not only suppose that some people ought to perform some actions, and that some outcomes are morally better or worse than others, but also that there are rights, duties, goodness, and other apparently abstract moral entities. What should we make of these entities, and the talk of these entities? It is not straighforward to account for these entities in other terms. On the other hand, this paper will argue that talk of such entities is not easily (...) eliminated from good moral theorising. Nor are the prospects for paraphrasing apparent talk about these entities into less committal terms very promising. We should either find a place in our ontology for these creatures of ethics, or explain how they can be employed as a convenient fiction. (shrink)

In this chapter, I first explore the possible meanings of the expression 'non-metaphysical religion' and its relation to the realism and cognitivism debates (as well as these debates' relation to each other). I then sketch out and defend the germs of an alternative semantics for religious language that I call 'religious imaginativism'. This semantics attempts to move us away from the realism-antirealism debates in Philosophy of Religion and in this sense might count as 'non-metaphysical'. At the same time, it allows (...) that religious utterances may be truth-evaluable. This creates space for a "theism with God" (and for a "God of theism") without being running into the problems confronted by more metaphysical approaches. (shrink)

This is a rough draft of the front matter and ch. 1, for a new book manuscript on metametaphysics.

This paper responds to John Burgess's ‘Mathematics and _Bleak House_’. While Burgess's rejection of hermeneutic fictionalism is accepted, it is argued that his two main attacks on revolutionary fictionalism fail to meet their target. Firstly, ‘philosophical modesty’ should not prevent philosophers from questioning the truth of claims made within successful practices, provided that the utility of those practices as they stand can be explained. Secondly, Carnapian scepticism concerning the meaningfulness of _metaphysical_ existence claims has no force against a _naturalized_ version (...) of fictionalism, according to which our ordinary standards of scientific evidence may show that we have no reason to believe the mathematical existence claims made within the context of our mathematical and scientific theories.

There is a significant difference between the words `is' and `exists' that has either been overlooked or under-appreciated by many philosophers. This difference comes in sentences that express existential quantification using `is', `exists', or their cognates, such as, "There are cookies in the jar," or, "There exists a strange species of fish that nobody has studied yet." Phrases such as `there are' and `there exists' are existential quantifier expressions, since they're used to express existential quantification. The orthodox view of these (...) expressions is that they are, in the words of David K. Lewis, "entirely synonymous and interchangeable". This dissertation presents and argues for an anti-orthodox view of meaning of `there is' and `there exists'. The root of the difference in meaning between the two expressions is that `there is' turns out to be context-sensitive, on the model of demonstratives like `this' or `that', while `there exists' is invariant in its meaning. These views are motivated through the introduction of a notion called `ontological robustness', which helps us evaluate the level of ontological commitment in our assertions. The anti-orthodox view is defended over orthodoxy through holistic arguments that compare the virtues of each theory, including such metrics as how they fare in accounting for our stubborn desire to talk about and quantify over nonexistent objects.

In the recent literature there has been some debate between advocates of deflationist and fictionalist positions in metaontology. The purpose of this paper is to advance the debate by reconsidering one objection presented by Amie Thomasson against fictionalist strategies in metaontology. The objection can be reconstructed in the following way. Fictionalists need to distinguish between the literal and the real content of sentences belonging to certain areas of discourse. In order to make that distinction, they need to assign different truth-conditions (...) to the real and the literal content. But it is hard to see what more is required for the literal content to be true than for the real content to be true. So, fictionalism is an unsatisfactory position. Here I offer a novel reply to Thomasson’s challenge. I argue that the literal and the real content need not be distinguished in terms of their truth-conditions; rather, they can be distinguished in terms of their different subject-matters, leaving it open whether their truth-conditions coincide or not. I explain how replying to Thomasson’s objection is crucial for deepening our understanding of fictionalist strategies in metaontology. (shrink)

I defend a unified fictionalism about modality and mathematics. First, I defend each view separately against internal objections. Then, I attempt a unified fictionalism by giving an analysis of truth in fiction which is neither modal nor platonistic. Finally, I explore the prospects for nominalistic unified fictionalism. ;In the first chapter, I defend modal fictionalism: the view that statements about possible worlds are best understood as claims about the content of a fiction, the 'many-worlds story'. I address the Brock-Rosen objection (...) that the fictionalist is a modal realist despite himself. I argue that Noonan's solution, the best response so far, is inadequate, and then offer an alternative fictionalist translation scheme for modal statements. ;In the second chapter, I defend mathematical fictionalism. Mathematical fictionalism is the view that mathematics is best understood as a fiction whose value is quite independent of its truth-value. Field argues for fictionalism in this sense by constructing nominalistic alternatives to standard physical theories. The aim is to establish that mathematical entities are 'dispensable for the purposes of science', and so to undermine the only reason we might have for believing in the literal truth of standard mathematics. I address an objection that the nominalization of current science would not suffice to establish the 'dispensability' of mathematical entities in the epistemologically relevant sense. I argue that there is a plausible interpretation of the indispensability argument according to which successful nominalization would establish that it is unreasonable to believe in mathematical entities. ;The most important challenge for any attempt at a unified fictionalism is to provide an account of truth in fiction that is neither implicitly modal nor implicitly platonistic. To this end, I offer in the third chapter an analysis of truth in a story which is based on a modified version of Walton's account of truth in fiction. ;A second challenge is to show that the timelessness and necessity of modal truth are compatible with the view that fictions are contingent and temporally restricted entities. In the final chapter, I argue this problem constitutes a genuine obstacle for a unified nominalistic fictionalism. (shrink)

In "How to Speak of the Colors", Mark Johnston’s claims that eliminativism would require us to jettison colour discourse. In this paper, I challenge Johnston’s claim. I argue that a particular version of eliminativism, i.e., prescriptive colour fictionalism, allows us to continue employing colour discourse as we have thus far in the absence of colours. In doing so, it employs statistical models in its base discourse to derive high-level statistical constructs that can be linked to the fiction via bridge principles.

_Free to read on publishers website_ In normal child development, both individual and group pretense first emerges at approximately two years of age. The metarepresentational account of pretense holds that children already have the concept PRETEND when they first engage in early group pretense. A behavioristic account suggests that early group pretense is analogous to early beliefs or desires and thus require no mental state concepts. I argue that a behavioral account does not explain the actual behavior observed in children (...) and it cannot explain how children come to understand that a specific action is one of pretense versus one of belief. I conclude that a mentalistic explanation of pretense best explains the behavior under consideration. (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.

Mental fictionalism maintains that: folk psychology is a false theory, but we should nonetheless keep using it, because it is useful, convenient, or otherwise beneficial to do so. We should treat folk psychology as a useful fiction—false, but valuable. Yet some argue that mental fictionalism is incoherent: if a mental fictionalist rejects folk psychology then she cannot appeal to fictions in an effort to keep folk psychological discourse around, because fictions presuppose the legitimacy of folk psychology. Call this the Argument (...) from Cognitive Collapse. In this paper, I defend several different mental fictionalist views against cognitive collapse. (shrink)

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)

This challenging study places fiction squarely at the centre of the discussion of metaphysics. Philosophers have traditionally treated fiction as involving a set of narrow problems in logic or the philosophy of language. By contrast Amie Thomasson argues that fiction has far-reaching implications for central problems of metaphysics. The book develops an 'artifactual' theory of fiction, whereby fictional characters are abstract artifacts as ordinary as laws or symphonies or works of literature. By understanding fictional characters we come to understand how (...) other cultural and social objects are established on the basis of the independent physical world and the mental states of human beings.

Are fictional characters such as Sherlock Holmes real? What can fiction tell us about the nature of truth and reality? In this excellent introduction to the problem of fictionalism R. M. Sainsbury covers the following key topics: what is fiction? realism about fictional objects, including the arguments that fictional objects are real but non-existent; real but non-factual; real but non-concrete the relationship between fictional characters and non-actual worlds fictional entities as abstract artefacts fiction and intentionality and the problem of irrealism (...) fictionalism about possible worlds moral fictionalism. R. M. Sainsbury makes extensive use of examples from fiction, such as Sherlock Holmes, Anna Karenina and Madame Bovary and examines the work of philosophers who have made significant contributions to the topic, including Meinong, David Lewis, and Bas Van Fraassen. Additional features include chapter summaries, annotated further reading and a glossary of technical terms, making _Fiction and Fictionalism_ ideal for those coming to the issue for the first time.

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.

is accounted for, among other things, in terms of particular relations between events (or states1) and places or times. Roughly speaking, an event α is said to occur in a place p (or interval t) if the spatial (temporal) extension of α is located in p (or t). Let the predicate ‘Occ’ denote such a relation. From this point of view, part of the content of the above sentences can be associated, respectively, with formulas such as.

I explore some of the reasons why, under specific circumstances, it may be rational to make-believe or imagine certain religious beliefs. Adopting a jargon familiar to certain contemporary philosophers, my main concern here is to assess what reasons can be given for adopting a fictionalist stance towards some religious beliefs. My understanding of fictionalism does not involve solely a propositional attitude but a broader stance, which may include certain acts of pretence. I also argue that a plausible reason to be (...) fictionalist about a specific set of religious beliefs and practices has to do with the value of some artistic creations; namely, those that require the adoption of a religious point of view for their understanding.

Fictionalists claim that instead of believing certain controversial propositions they accept them nonseriously, as useful make-believe. In this way they present themselves as having an austere ontology despite the apparent ontological commitments of their discourse. Some philosophers object that this plays on a distinction without a difference: the fictionalist’s would-be nonserious acceptance is the most we can do for the relevant content acceptance-wise, hence such acceptance is no different from what we ordinarily call ‘belief’ and should be so called. They (...) conclude that it is subject to the norms applicable to paradigmatic empirical beliefs, and hence, pace fictionalists, ontological commitments must be taken seriously. I disentangle three strands in the objector’s thought: the ‘What more can you ask for?’ intuition, a linguistic/ conceptual claim, and a claim about norms. I argue that the former two are compatible with ontological deflationism, and therefore do not entail applicability of the norms. Nevertheless, if indeed there is no more robust acceptance with which to contrast the supposed nonserious acceptance, then the fictionalist’s claim to austere ontology must be abandoned. Is there a reason to suppose there is any merit to the distinction-without-a-difference charge? I argue that there is, clarify it, and defend against objections, focusing on Daly 2008. (shrink)

In this paper we explain our pretense account of truth-talk and apply it in a diagnosis and treatment of the Liar Paradox. We begin by assuming that some form of deflationism is the correct approach to the topic of truth. We then briefly motivate the idea that all T-deflationists should endorse a fictionalist view of truth-talk, and, after distinguishing pretense-involving fictionalism (PIF) from error- theoretic fictionalism (ETF), explain the merits of the former over the latter. After presenting the basic framework (...) of our PIF account of truth-talk, we demonstrate a few advantages it offers over T-deflationist accounts that do not explicitly acknowledge pretense at work in the discourse. In turning to the Liar Paradox, we explain how the quasi-anaphoric functioning that our account attributes to truth-talk provides a diagnosis of the Liar Paradox (and other instances of semantic pathology) as having no content—in the sense of not specifying any of what we call M-conditions. At the same time, however, we vindicate the intuition that we can understand liar sentences, thereby avoiding one standard objection to “meaningless strategy” responses to the Liar Paradox. With this diagnosis in place, we then, by way of treatment, introduce a new predicate, ‘semantically defective’, and show how the explanation we give for its application allows for a consistent, yet revenge-immune, (dis)solution of the Liar Paradox, and semantic pathology generally.

Fictionalism and deflationism are two moderate meta-ontological positions that try to occupy a middle ground between the extremes of heavy-duty realism and hard-line eliminativism. Deflationists believe that the existence of certain entities (e.g.: numbers) can be established by means of ‘easy’ arguments—arguments that, supposedly, rely solely on uncontroversial premises and trivial inferences. Fictionalists, however, find easy arguments unconvincing. Amie Thomasson has recently argued that, in their criticism of easy arguments, fictionalists beg the question against deflationism and that the fictionalist alternative (...) interpretation of easy arguments is untenable. In this paper, I argue that both charges are unsubstantiated. Properly understood, the fictionalist’s objection to ‘easy’ arguments takes the form of a dilemma—either the premises of ‘easy’ arguments are not truly uncontroversial or the inferences on which they rely are not truly trivial. Moreover, I argue not only that, contrary to what Thomasson claims, the fictionalist’s interpretation of easy argument is tenable but that the fictionalist might, in fact, have a better explanation of the seemingly trivial nature of the inferences involved in easy arguments than the deflationist’s.

The aim of the paper is to compare two kinds of anti-realism about possible worlds: a version of instrumentalism and fictionalism. The former is inspired by M. Eklund’s paper Fiction, indifference and ontology, according to which ontologically uncommitted truth conditions for possible-world sentences are reducible to their instrumental utility and truth conditions of their literally true interpretations. The latter is inspired by S. Yablo’s work on fictionalism, according to which whenever we engage in possible-world talk, we engage in a game (...) of make-believe, pretending that there exist such entities as possible worlds and possiblia , which makes possible-world sentences fictionally true within the game of make-believe. Instrumentalists promise to achieve ontologically uncommitted interpretation of possible-world talk without incurring ideological costs to which fictionalists are obliged, because of their doctrine of fictional truth. Contrary to that, I argue that one needs to tell a story why one finds possible-world talk a useful device and that fictionalists’ doctrine of fictional truth can be taken as an attempt to provide such an explanation. For example, most of fictionalists — by trying to save realists’ semantics for possible-world talk — can save to some degree such features of this talk as extensionality, which is partially responsible for its instrumental utility. Instrumentalism, on the other hand, lacks means of providing such a story. Hence, we should prefer more comprehensive account of usefulness of possible-world talk, even if it generates their own difficulties connected with the relation between truth conditions of possible-world sentences within a game of make-believe and truth conditions of literary true sentences about a realm of reality to which we wish to apply possible-world analysis. Key words ANTI-REALIZM, INSTRUMENTALISM, FICTIONALISM. (shrink)

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)

Kendall Walton’s pretense theory, like its rivals, says that what’s true in a fiction F depends in part on the importation of background propositions into F. The aim of this paper is to present, explain, and defend a brief yet straightforward argument–one which exploits the specific mechanism by which the pretense theory says propositions are imported into fictions–for the falsity of the pretense theory.

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)

This is a survey of contemporary work on ‘fictionalism in metaphysics’, a term that is taken to signify both the place of fictionalism as a distinctive anti‐realist metaphysics in which usefulness rather than truth is the norm of acceptance, and the fact that philosophers have given fictionalist treatments of a range of specifically metaphysical notions.

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 fictionalism in general (...) because the currently popular variety is the one that deals best with the Quine-Putnam indispensability argument. (shrink)
