Abstract
Characteristic of model based science is its attachment to idealizations and abstractions. Idealizations are expressed by statements known to be false. Abstractions are suppressors of what is known to be true. Idealizations over-represent empirical phenomena. Abstractions under-represent them. In a sense, idealization and abstractions are one another’s duals. Either way, they are purposeful distortions of phenomena on the ground. Sometimes phenomena on the ground approximate to what their idealizations say of them. Sometimes nothing in nature approaches them in any finite degree. So wide is this gulf between reality and idealization that Nancy Cartwright was moved to say of them that they are “pure fictions”.

In mainstream approaches to the semantics of natural language, this order is typically reversed—〈reference, truth, inference〉. Reasons for the switch in fictional contexts are laid out in Woods and an Isenberg [11].

Also important for scientific models are abstractions, whose principal alethic significance is the suppression of what is true on the ground. For further discussion, see Woods and Rosales [22].

Concerning which see also Godfrey-Smith [23]: “Scientists, whose business is understanding the empirical world, often spend their time considering things that are known not to be parts of that world. Standard examples are ideal gases and frictionless planes. Examples also include infinitely large populations in biology, neural networks which learn using biologically unrealistic rules, and the wholly rational and self-interested agents of various social-scientific models …. A natural first description of these things is as fictions, creatures of the imagination.” (p. 101).

It might be thought that these infinite gaps could be made subject to variable shrinkage by the devices of probability. A statement having a probability of 0.8 is one with a higher probability than a statement whose value is 0.6. This is so, but not on point. The highest probability is 1.0. Perhaps we could say that statements having this value are ideally probable. At least, if we did say this, people would know what we meant. But 0.6, 0.8 and 1.0 are real numbers. Real numbers are everywhere dense. No real number (save for self) is any closer to 1.0 than any other. The relation of having a higher probability than is not a matter of having a value that lies closer than the alternative to the ideal probability. Of course 8 is a number that lies closer to 10 than 6 does. But these are natural numbers. Other than 1 and 0 numbers on the natural line are not probabilities.

Batterman, among others, writes astutely about the philosophical questions raised by the ineliminable presence of unapproachable idealizations in theoretical science, but with no mention of the idea that they are fictions. See, for example, his [24, 25]. Other sceptics of note are Teller [26] and Giere [27], both in Suarez [8].

Fine writes: “Over the last few years the realism-antirealism arguments … and a somewhat larger number of epithets …. When an especially derisive antirealist label is wanted, one can fall back on the term “fictionalist”, coupled with a dismissive reference to Vaihinger and his ridiculous philosophy of ‘As If’”. (“Fictionalism”, Midwest Studies in Philosophy, 18 (1993), 1–18, p. 1.) Fine’s use of “ridiculous” is a matter of mention rather than use. Fine is no Vaihingerian, but he is far from thinking that The Philosophy of ‘As If” is ridiculous.

This is not to say that façon de parler fictionalism is inherently antirealist. Fictional realists hold that Holmes is a real thing, albeit not in the way that we ourselves are. Realistically inclined idealizers claim that infinite populations are real, albeit not in the way that the population of London is. If the attribution of fictionality to those idealizations is just another way of saying that they are real, but not in the way that the population of London is, the attributor is a façon de parler fictionalist.

See again Suárez and Frigg. An exception is Vaihinger’s [31], the book arises from Vaihinger’s doctoral dissertation of 1877. Meinongean theories, in turn, are adaptations of an antecedently developed metaphysical theory. See again Parsons’ Nonexistent Objects and Jacquette’s Meinongean Logic. Also important is Bonevac’s home-made mathematical fictionalism, in “Fictionalism”, Sects. 7.2–7.8, made especially interesting by the fact that Bonevac is not himself a fictionalist.

Apart from their potential as indispensable-falsehood solutions, Ramsey and Craig eliminations are faced with internal difficulties. If, for example, we Ramseyized an entire theory, except for its logical particles, then Löwenheim-Skolem considerations would now apply and with them, some would say, the loss of the theory’s scientific content. As for Craig’s claim that the o-consequences are invariant under the transition from S to So, there is no effective way of producing these o-consequences in the first place without the aid of t-terms. So, there is an important sense in which the transformation doesn’t cancel t-term dependencies.

This is especially true of criminal cases at common law. Acquittals constitute the legal fact of innocence. But legal innocence significantly outpaces actual innocence. This is deliberate. It arises from a social policy designed to minimize wrongful convictions. Better a false acquittal than a false conviction.

“On Sinn and Bedeutung” translated by Max Black, in Michael Beaney editor The Frege Reader, pages 151-171, Oxford: Blackwell, 1997; p. 157. In “On denoting”, Russell too gives fictional sentences the brush-off. They are, he says, sometimes true in a “secondary sense”, without pausing to say what this sense might be. Strawson displays a similar casualness. In [67], he allows that sentences in Pickwick Papers are about Mr. Pickwick only in some (wholly unexplained) sense of “about”.

Appendix
Present-day theories of literary fictions reflect sharply different ways of cutting the cake. Here are two of them, made possible by subscription to or rejection of the following pair of assumptions:
Parmenides’ Law. Quantification and reference are existentially loaded. There is nothing that doesn’t exist. It is not possible to refer to what isn’t.
The Non-existence Postulate. The purported objects and events of fiction do not exist. No object is a fictional object. No event is a fictional event.
It is doubtful that any philosophical claim could divide considered judgement more deeply than these two. Certainly they are, in their intractability, no improvement on the divisiveness occasioned by realism-antirealism wrangles in science or anywhere else. Why, then, for our philosophical anxieties about science, would we seek succor in the realist-antirealist war zones occasioned by the Law and the Postulate? Desperate times call for desperate measures, but isn’t this going too far?
A further point on which literary semanticists are divided is
Frege’s Dismissal. Since literature doesn’t matter for science, a literary semantics would be of only marginal interest.Footnote 59
In a rough and ready way, the first two of these clashing standpoints motivate the (incomplete) sample below, with the third somewhat orthogonal to them as in a second grouping, also just a sample.Footnote 60
List One
Pro the law and the postulate | Contra the law and the postulate |
---|---|
Sayso semantics.Footnote 62 | Meinongean theoriesFootnote 63 |
Pretense theoriesFootnote 64 | Existence-neutral logicsFootnote 65 |
Frege-Russell theoriesFootnote 66 | Artifactual theoriesFootnote 67 |
Free logicsFootnote 68 | Fictional worlds theoriesFootnote 69 |
Theories of substitutional quantificationFootnote 70 |
List Two
Pro Frege’s dismissal | Con Frege’s dismissal |
---|---|
Free logics | Sayso semantics |
Frege-Russell theories | Meinongean theories |
Strawson’s “On Referring” | Pretense theories |
Artifactual theories | |
Fictional worlds theories |
There is in these multiplicities fair warning. As we have it now, the state of play in the logics of literary fictions give uncertain guidance to the realist-antirealist debate in science, or elsewhere. It is a conflicted matter in the philosophy of science. It is a conflicted matter in the philosophy of literature. So where in the philosophy of literature is the payoff for the philosophy of science?
