Scientific Fictionalism

This paper defends an approach to modeling and models in science that is against model fictionalism of a recent stripe (the “new fictionalism” that takes models to be abstract entities that are analogous to works of fiction). It further argues that there is a version of fictionalism on models to which my approach is neutral and which only makes sense if one adopts a special sort of antirealism (e.g. constructive empiricism). Otherwise, my approach strongly suggests that one stays away from (...) fictionalism and embraces realism directly. (shrink)

Oswald Spengler is best known as a philosopher of history. However, one can trace in volume one of his The Decline of the West a sustained consideration of philosophical issues pertaining to the nature and practice of science that I suggest can be considered to be a philosophy of science. Not only has Spengler’s philosophy of science been largely overlooked, so too has its peculiar fictionalist character. By elaborating on the fictionalist character of Spengler’s scientific views I shall consider his (...) work in comparison with that of Hans Vaihinger, a contemporary of Spengler and noted fictionalist with regards to science. This comparison not only supports my interpretation of Spengler’s philosophy of science as fictionalist, it also throws into relief the numerous affinities between the thought of two philosophers who are not usually associated, in particular with regards to their accounts of the origins of science in the structures of human consciousness. This fictionalist affinity in turn suggests the need for a wholesale reappraisal of Spengler’s philosophical outlook. (shrink)

Is there a role for aesthetic judgements in science? One aspect of scientific practice, the use of thought experiments, has a clear aesthetic dimension. Thought experiments are creatively produced artefacts that are designed to engage the imagination. Comparisons have been made between scientific (and philosophical) thought experiments and other aesthetically appreciated objects. In particular, thought experiments are said to share qualities with literary fiction as they invite us to imagine a fictional scenario and often have a narrative form (Elgin 2014). (...) But philosophical discussions of aesthetics in science have focused mainly on the epistemic role of beauty and elegance when it comes to theories and mathematical proofs, and thought experiments have been widely overlooked. My aim in this chapter is to address how the aesthetic choices scientists make in the design of a thought experiment contribute to its function: to communicate, convince, or explain a theory or phenomenon. A key issue is whether any aesthetic features in science provide anything beyond catching our attention, or are at best, a mere heuristic aid. I respond to accounts that argue this way and show how formulation is important in scientific thought experiments and, similarly to literary fictions, there is more than one way of interpreting a thought experiment scenario. I end by considering which literary examples are most appropriate when making comparisons with thought experiments. As a result, the difference between representations in art and science raised in current discussions is not as stark as it has been made out to be, and science is a more heterogeneous practice than has been allowed. Part of the value of thought experiments in scientific practice includes the qualities they share with literary works. (shrink)

Theoretical models are widely held as sources of knowledge of reality. Imagination is vital to their development and to the generation of plausible hypotheses about reality. But how can imagination, which is typically held to be completely free, effectively instruct us about reality? In this paper I argue that the key to answering this question is in constrained uses of imagination. More specifically, I identify make-believe as the right notion of imagination at work in modelling. I propose the first overarching (...) taxonomy of types of constraints on scientific imagination that enables knowledge of reality. And I identify two main kinds of knowledge enabled by models, knowledge of the imaginary scenario specified by models and knowledge of reality. (shrink)

At the beginning of the twentieth century, theorists developed approaches to Nietzsche’s philosophy that provided an alternative to the received view, some of them suggesting that his view of truth may be his most important and original contribution. It has further been argued that Vaihinger’s fictionalism is the paradigm within which Nietzsche’s view can be properly contextualized. As will be shown, this idea is both viable and fruitful for solving certain interpretive issues raised in recent Nietzsche scholarship.

On the notion of responsibility employed by John Passmore in his classic Man’s Responsibility for Nature, the relationship of responsibility can only hold between persons (human beings, subjects), or groups and communities of them, and other persons. And in this relationship the persons that are responsible 'to' other persons are responsible 'for' how their actions affect these other persons, not to the direct object of these actions (in this case: nature). If this is correct, we cannot be responsible to nature (...) without conceiving of it as a ‘pseudo-person’, as Passmore calls it. However, non-anthropocentric environmental ethics requires such a moral relationship. The question is, therefore, how this can be allowed in a metaphysically acceptable way. To answer this I first provide an account of what it means to stand in the relation of being ‘responsible to’. Next, I describe two major paradigmatic examples of the metaphysics of nature that perfectly match the thesis that we can, and should, be responsible to nature (the Spinoza-inspired view and the Gaia hypothesis). Unfortunately, they have to be rejected for common sense or naturalist reasons. Finally, I therefore defend a 'fictionalist' view of nature (as person-like) that allows for this relationship.

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...

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)
