Models as Make-Believe offers a new approach to scientific modelling by looking to an unlikely source of inspiration: the dolls and toy trucks of children's games of make-believe.

In this paper I propose an account of representation for scientific models based on Kendall Walton’s ‘make-believe’ theory of representation in art. I first set out the problem of scientific representation and respond to a recent argument due to Craig Callender and Jonathan Cohen, which aims to show that the problem may be easily dismissed. I then introduce my account of models as props in games of make-believe and show how it offers a solution to the problem. Finally, I demonstrate (...) an important advantage my account has over other theories of scientific representation. All existing theories analyse scientific representation in terms of relations, such as similarity or denotation. By contrast, my account does not take representation in modelling to be essentially relational. For this reason, it can accommodate a group of models often ignored in discussions of scientific representation, namely models which are representational but which represent no actual object.

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)

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)

The descriptions and theoretical laws scientists write down when they model a system are often false of any real system. And yet we commonly talk as if there were objects that satisfy the scientists’ assumptions and as if we may learn about their properties. Many attempt to make sense of this by taking the scientists’ descriptions and theoretical laws to define abstract or fictional entities. In this paper, I propose an alternative account of theoretical modelling that draws upon Kendall Walton’s (...) ‘make-believe’ theory of representation in art. I argue that this account allows us to understand theoretical modelling without positing any object of which scientists’ modelling assumptions are true. (shrink)

Recent philosophy of science has seen a number of attempts to understand scientific models by looking to theories of fiction. In previous work, I have offered an account of models that draws on Kendall Walton’s ‘make-believe’ theory of art. According to this account, models function as ‘props’ in games of make-believe, like children’s dolls or toy trucks. In this paper, I assess the make-believe view through an empirical study of molecular models. I suggest that the view gains support when we (...) look at the way that these models are used and the attitude that users take towards them. Users’ interaction with molecular models suggests that they do imagine the models to be molecules, in much the same way that children imagine a doll to be a baby. Furthermore, I argue, users of molecular models imagine themselves viewing and manipulating molecules, just as children playing with a doll might imagine themselves looking at a baby or feeding it. Recognising this ‘participation’ in modelling, I suggest, points towards a new account of how models are used to learn about the world, and helps us to understand the value that scientists sometimes place on three-dimensional, physical models over other forms of representation.

Modeling is central to scientific inquiry. It also depends heavily upon the imagination. In modeling, scientists seem to turn their attention away from the complexity of the real world to imagine a realm of perfect spheres, frictionless planes and perfect rational agents. Modeling poses many questions. What are models? How do they relate to the real world? Recently, a number of philosophers have addressed these questions by focusing on the role of the imagination in modeling. Some have also drawn parallels (...) between models and fiction. This chapter examines these approaches to scientific modeling and considers the challenges they face. (shrink)

Recent work in epistemology and philosophy of science has argued that understanding is an important cognitive state that philosophers should seek to analyse. This paper offers a new perspective on understanding by looking to work in philosophy of mind and cognitive science. Understanding is normally taken to be inside the head. I argue that this view is mistaken. Often, understanding is a state that criss-crosses brain, body and world. To support this claim, I draw on extended cognition, a burgeoning framework (...) in cognitive science that stresses the crucial role played by tools, material representations and the wider environment in our cognitive processes. I defend an extended view of understanding against likely objections and argue that it has important consequences for questions concerning the nature of understanding and its relationship to explanation.

The similarity view of scientific representation has recently been subjected to strong criticism. Much of this criticism has been directed against a ?naive? similarity account, which tries to explain representation solely in terms of similarity between scientific models and the world. This article examines the more sophisticated account offered by the similarity view's leading proponent, Ronald Giere. In contrast to the naive account, Giere's account appeals to the role played by the scientists using a scientific model. A similar move is (...) often made by defenders of resemblance theories of depiction, who invoke the role played by the artist, or by the viewers of a painting. In this article I look to debates over depiction to assess the difficulties facing those who wish to defend the similarity view of scientific representation. I then turn to examine Giere's account. Ultimately, I argue, this account is unsuccessful: while appealing to the role of scientists offers a promising way to defend the similarity view, Giere's own account does not capture what it is that scientists do when they use a model to represent the world.

One important debate between scientific realists and constructive empiricists concerns whether we observe things using instruments. This paper offers a new perspective on the debate over instruments by looking to recent discussion in philosophy of mind and cognitive science. Realists often speak of instruments as ‘extensions’ to our senses. I ask whether the realist may strengthen her view by drawing on the extended mind thesis. Proponents of the extended mind thesis claim that cognitive processes can sometimes extend beyond our brains (...) and bodies into the environment. I suggest that the extended mind thesis offers a way to make sense of realists’ talk of instruments as extensions to the senses and that it provides the realist with a new argument against the constructive empiricist view of instruments.

This chapter introduces several versions of mental fictionalism, along with the main lines of objection and reply. It begins by considering the debate between eliminative materialism (“eliminativism”) versus realism about mental states as conceived in “folk psychology” (i.e., beliefs, desires, intentions, etc.). Mental fictionalism offers a way to transcend the debate by allowing talk of mental states without a commitment to realism. The idea is to treat folk psychology as a “story” and three different elaborations of this are reviewed. First, (...) prefix semantics paraphrases a sentence like ‘Biden believes that Trump lost’ as ‘According to folk psychology, Biden believes that Trump lost’, whereby ontological commitment to belief is avoided. Similarly, pretense theory suggests that we do not assert ‘Biden believes that Trump lost’, but only pretend to assert it. Third, affective theory proposes that such discourse is used in a metaphorical way to understand a person’s affective and dispositional states vis-a-vis the community. The main objections concern whether folk psychology has the features of storytelling, and whether mental fictionalism ends up being self-refuting. The chapter also recaps a less discussed fictionalist view about “qualia” or phenomenal states, and closes by summarizing the papers contained in the volume. (shrink)

Distributed cognition (d-cog) claims that many cognitive processes are distributed across groups and the surrounding material and cultural environment. Recently, Nancy Nersessian, Ronald Giere, and others have suggested that a d-cog approach might allow us to bring together cognitive and social theories of science. I explore this idea by focusing on the specific interpretation of d-cog found in Edwin Hutchins' canonical text Cognition in the wild. First, I examine the scope of a d-cog approach to science, showing that there are (...) important disputes between cognitive and social theorists on which d-cog remains silent. Second, I suggest that, where social explanations can be recast in d-cog terms, this reformulation will not be acceptable to all social theorists. Finally, I ask how we should make sense of the claim that, on a d-cog analysis, social factors are cognitive factors. (shrink)

What is the relationship between mental states and items of material culture, like notebooks, maps or lists? The extended mind thesis offers an influential and controversial answer to this question. According to ExM, items of material culture can form part of the material basis for our mental states. Although ExM offers a radical view of the location of mental states, it fits comfortably with a traditional, representationalist account of the nature of those states. I argue that proponents of ExM would (...) do better to adopt a fictionalist approach to mental states. In so doing, I suggest, they could retain the important insights underlying the extended mind thesis, while avoiding its more problematic consequences. (shrink)

As If: Idealization and Ideals, by AppiahKwame Anthony. Cambridge, MA: Harvard University Press, 2017. Pp. xvi + 218.

Recently, a number of authors have suggested that we understand scientific models in the same way as fictional characters, like Sherlock Holmes. The biggest challenge for this approach concerns the ontology of fictional characters. I consider two responses to this challenge, given by Roman Frigg, Ronald Giere and Peter Godfrey-Smith, and argue that neither is successful. I then suggest an alternative approach. While parallels with fiction are useful, I argue that models of real systems are more aptly compared to works (...) that portray real people, like the Emperor Claudius. This approach will allow us to avoid problems with fictional characters. (shrink)

What are mental states? When we talk about people’s beliefs or desires, are we talking about what is happening inside their heads? If so, might cognitive science show that we are wrong? Might it turn out that mental states do not exist? Mental fictionalism offers a new approach to these longstanding questions about the mind. Its core idea is that mental states are useful fictions. When we talk about mental states, we are not formulating hypotheses about people’s inner machinery. Instead, (...) we simply talk "as if" people had certain inner states, such as beliefs or desires, in order to make sense of their behaviour. This is the first book dedicated to exploring mental fictionalism. Featuring contributions from established authors as well as up-and-coming scholars in this burgeoning field, the book reveals the exciting potential of a fictionalist approach to the mind, as well as the challenges it faces. In doing so, it offers a fresh perspective on foundational debates in the philosophy of mind, such as the nature of mental states and folk psychology, as well as hot topics in the field, such as embodied cognition and mental representation.

This paper is a review of Suarez, M. (ed.) Fictions in Science (Routledge).

By now it has been pretty well established that the Flemish Jesuit Leonardus Lessius was an economist of the highest grade. Joseph A. Schumpeter, perhaps the 20th century’s most important historian of economics, afforded Lessius more than ample mention in his monumental work, History of Economic Analysis. In Interest and Usury, Schumpeter’s pupil, Bernard W. Dempsey, likewise gave Lessius generous attention. The Belgian historian Raymond de Roover, however, who considered Lessius to be primarily a deserving epigone of the famous ‘Salamanca (...) School’, did not completely share their enthusiasm, at least initially. De Roover’s somewhat lukewarm attitude was, nevertheless, drowned out by the laudatory contribution of Barry T. Gordon on the subject in his Economic Analysis Before Adam Smith. Robert Beutels brought respect to Lessius’ work in his bio-bibliographical essay published in 1987 and restored something of the honour due to Lessius which, according to Beutels, he had been unjustly denied, certainly in his own land.The image of Lessius presented by all these authors is uncommonly fresh, yet at the same time surprisingly familiar. In their works they have shown him to be a modern thinker who merits comparison with contemporary economists. His analyses give witness to his profound insight into the economy of his day and are still relevant, thought not directly applicable, for economists today. The market principle, portfolio theory, the quantity theory of money, and much more can, according to the authors we have mentioned, be found in Lessius. But does this rather trendy image of Lessius agree with the historical reality?An appropriate way to begin answering this question would be to examine his discussion on the lending of money and the taking of interest in his monumental tractate of 1605, On Justice and Law . Did Lessius endorse or reject the traditional proscription against usury? When did he consider it permissible to claim interest? To what extent did his moral judgment depend on an economic analysis of the phenomenon of interest? Perhaps the answers to these questions will enable us to judge Lessius as both economist and ethicist, as he rightly deserves. (shrink)

Upshot: Adam Toon’s book is a development in the fictionalist view of scientific modelling. Although his fictionalist account is realistic and representational, Toon’s input to the theory can contribute to the constructivist discourse. The introduction of a direct view on models’ fictions brings this theory close to non-dualism and living practice views.

Review of "Mental Fictionalism: Philosophical Explorations" by Tamás Demeter, Ted Parent, and Adam Toon.

Roman Frigg and Adam Toon, both, defend a fictionalist view of scientific modeling. One fundamental thesis of their view is that scientists are participating in games of make-believe when they study models in order to learn about the models themselves and about target systems represented by the models. In this paper, the epistemology of these two fictionalist views is critically discussed. I will argue that both views can give an explanation of how scientists learn about models they are (...) studying. However, how the use of models can foster an understanding of target systems is not sufficiently accounted for by Frigg and Toon. (shrink)

The theory of reflexive modernization plausibly advocates postnational cosmopolitanism. As the nation state is eroding today, we are becoming citizens of a ‘global risk society’ whose unity and cohesion is generated by the risk that is threatening us world-wide. By the same token, this world risk society is no longer unified in any political sense. There is no world state; its very idea is even rejected. In this sense, the cosmopolitanism argued for in the theory of reflexive modernization proves predominantly (...) to be an extrapolation of civil society on a global scale, while, strictly speaking, having no cosmo‘political’ counterpart. Building on Marcel Gauchet’s political philosophy, the article questions the cosmopolitanism-beyond-the-political position of the theory of reflexive modernization. To do so, it goes substantially into Gauchet’s view of the representational role of the political as an essential dimension in society formation. (shrink)

Populisme. Sinds extreem rechts recent een bepaald soort salonfähigkeit heeft weten te verwerven in het democratische bestel wordt de term door zelfverklaarde democraten te pas en te onpas gehanteerd om bijvoorkeur ‘rechtse’, maar bij uitbreiding ook alle andere tegenstanders te desavoueren die uit zijn op al te gemakkelijk politiek succes. Vanuit dat perspectief veroorzaakt de term ‘populisme’ geen enkel probleem: het is een dankbare politieke diskwalificatie die iedereen graag gebruikt, maar die niemand graag krijgt toebedeeld.

When one encounters disagreement about the truth of a factual claim from a trusted advisor who has access to all of one's evidence, should that move one in the direction of the advisor's view? Conciliatory views on disagreement say "yes, at least a little." Such views are extremely natural, but they can give incoherent advice when the issue under dispute is disagreement itself. So conciliatory views stand refuted. But despite first appearances, this makes no trouble for *partly* conciliatory views: views (...) that recommend giving ground in the face of disagreement about many matters, but not about disagreement itself.

The claim of this paper is that the everyday functions of knowledge make most sense if we see knowledge as contrastive. That is, we can best understand how the concept does what it does by thinking in terms of a relation “a knows that p rather than q.” There is always a contrast with an alternative. Contrastive interpretations of knowledge, and objections to them, have become fairly common in recent philosophy. The version defended here is fairly mild in that there (...) is no suggestion that we cannot think in terms of a simpler not explicitly contrastive relation “a knows that p.” Some, for instance Schaffer (2005) and Karjalainen and Morton (2003), have hinted that this stronger possibility may be right. But all that I am arguing now is that facts that are easily expressed in contrastive terms are vital to understanding why we need the concept of knowledge. In a piece that is in some ways a companion to this one ("Contrastivism" in Duncan Pritchard and Sven Bernecker, eds. The Routledge Companion to Epistemology. Routledge 2010, 513-522), I give a general survey of theories of contrastive knowledge and the differences between them. (shrink)

This essay sets up a dialogue between Lefort’s view on the relationship between the state and modern society and Foucault’s thesis of a governmental turn in the modern power regime, whereby the relations between state and society are thoroughly redrawn. What are the main results? 1) Whereas Lefort’s political ontology leaves room for divergent agencies from which the symbolic institution of the social may unfold, his preoccupation with democracy leans him to inseparably link the symbolic institution of modern society with (...) the functioning of the modern state. 2) By contrast, Foucault’s history of governmentality documents a shift from the political and legal power regime to the biopolitical regime. This shift seems to be accompanied by a turn in the regime of the symbolic institution of modern society. Where that institution hitherto relied on the state, today, a symbiosis of state and neoliberal governmentality seems to be taking over. 3) This shift in power regimes brings along major problems. In political respect, it leads to a re-adjustment of the instituting representations of contemporary society, to a depoliticization of political and social relations, and to the erosion of democracy.

Many favor representationalism about color experience. To a first approximation, this view holds that experiencing is like believing. In particular, like believing, experiencing is a matter of representing the world to be a certain way. Once you view color experience along these lines, you face a big question: do our color experiences represent the world as it really is? For instance, suppose you see a tomato. Representationalists claim that having an experience with this sensory character is necessarily connected with representing (...) a distinctive quality as pervading a round area out there in external space. Let us call it “sensible redness” to highlight the fact that the representation of this property is necessarily connected with the sensory character of the experience. Is this property, sensible redness, really co-instantiated with roundness out there in the space before you? (shrink)

In order to predict and explain behavior, one cannot specify the mental state of an agent merely by saying what information she possesses. Instead one must specify what information is available to an agent relative to various purposes. Specifying mental states in this way allows us to accommodate cases of imperfect recall, cognitive accomplishments involved in logical deduction, the mental states of confused or fragmented subjects, and the difference between propositional knowledge and know-how .

Some philosophical theories of the nature of color aim to respect a "common sense" conception of color: aligning with the common sense conception is supposed to speak in favor of a theory and conflicting with it is supposed to speak against a theory. In this paper, we argue that the idea of a "common sense" conception of color that philosophers of color have relied upon is overly simplistic. By drawing on experimental and historical evidence, we show how conceptions of color (...) vary along several dimensions and how even supposedly "core" components of the contemporary "common sense" conception of color are less stable than they have been thought to be.

In this paper, I do a few things. I develop a (largely) empirical argument against naïve realism (Campbell, Martin, others) and for representationalism. I answer Papineau’s recent paper “Against Representationalism (about Experience)”. And I develop a new puzzle for representationalists.

Quantum mechanics is humanity's finest scientific achievement. It explains why the sun shines and how your eyes can see. It's the theory behind the LEDs in your phone and the nuclear hearts of space probes. Every physicist agrees quantum physics is spectacularly successful. But ask them what quantum physics means, and the result will be a brawl. At stake is the nature of the Universe itself. What does it mean for something to be real? What is the role of consciousness (...) in the Universe? And do quantum rules apply to very small objects like electrons and protons, but not us? In What is Real?, Adam Becker brings to vivid life the brave researchers whose quest for the truth led them to challenge Bohr: David Bohm, who picked up Einstein's mantle and sought to make quantum mechanics deterministic, all while being hounded by the forces of McCarthyism; Hugh Everett, who argued that everything, big and small, must be governed by the same rules; and John Bell, who went to great lengths to eradicate the power of the god-like observer from the core of quantum physics. And they paid dearly, their reputations, careers, and sometimes lives ruined completely. But history has been kinder to them than their contemporaries were. As Becker shows, the brave intellectual giants have inspired a growing army of physicists and philosophers intent both on making a philosophically more satisfying theory of the universe and a more useful one as well. A gripping story of some of humanity's greatest ideas and the high cost with which many have pursued them, What is Real? is intellectual history at its passionate best. (shrink)

This article gives an overview of the nursing ethics arguments on euthanasia in general, and on nurses' involvement in euthanasia in particular, through an argument-based literature review. An in-depth study of these arguments in this literature will enable nurses to engage in the euthanasia debate. We critically appraised 41 publications published between January 1987 and June 2007. Nursing ethics arguments on (nurses' involvement in) euthanasia are guided primarily by the principles of respect for autonomy, nonmaleficence, beneficence and justice. Ethical arguments (...) related to the nursing profession are described. From a care perspective, we discuss arguments that evaluate to what degree euthanasia can be considered positively or negatively as a form of good nursing care. Most arguments in the principle-, profession- and care-orientated approaches to nursing ethics are used both pro and contra euthanasia in general, and nurses' involvement in euthanasia in particular.

The Carol J. Adams Reader gathers together Adams's foundational and recent articles in the fields of critical studies, animal studies, media studies, vegan studies, ecofeminism and feminism, as well as relevant interviews and conversations in which Adams identifies key concepts and new developments in her decades-long work. This volume, a companion to The Sexual Politics of Meat (Bloomsbury Revelations), offers insight into a variety of urgent issues for our contemporary world: Why do batterers harm animals? What is the relationship between (...) genocide and attitudes toward other animals? How do activism and theory feed each other? How do race, gender, and species categories interact in strengthening oppressive attitudes? In clear language, Adams identifies the often hidden aspects of cultural presumptions. The essays and conversations found here capture the decades-long energy and vision that continue to shape new ways of thinking about and responding to oppression. (shrink)

How best to think about quantum systems under permutation invariance is a question that has received a great deal of attention in the literature. But very little attention has been paid to taking seriously the proposal that permutation invariance reflects a representational redundancy in the formalism. Under such a proposal, it is far from obvious how a constituent quantum system is represented. Consequently, it is also far from obvious how quantum systems compose to form assemblies, i.e. what is the formal (...) structure of their relations of parthood, overlap and fusion. In this paper, I explore one proposal for the case of fermions and their assemblies. According to this proposal, fermionic assemblies which are not entangled—in some heterodox, but natural sense of ‘entangled’—provide a prima facie counterexample to classical mereology. This result is puzzling; but, I argue, no more intolerable than any other available interpretative option. (shrink)

The problem of trust in social relationships was central to the emergence of the modern form of civil society and much discussed by social and political philosophers of the early modern period. Over the past few years, in response to the profound changes associated with postmodernity, trust has returned to the attention of political scientists, sociologists, economists, and public policy analysts. In this sequel to his widely admired book, The Idea of Civil Society, Adam Seligman analyzes trust as a (...) fundamental issue of our present social relationships. Setting his discussion in historical and intellectual context, Seligman asks whether trust--which many contemporary critics, from Robert Putnam through Francis Fukuyama, identify as essential in creating a cohesive society--can continue to serve this vital role. Seligman traverses a wide range of examples, from the minutiae of everyday manners to central problems of political and economic life, showing throughout how civility and trust are being displaced in contemporary life by new "external' system constraints inimical to the development of trust. Disturbingly, Seligman shows that trust is losing its unifying power precisely because the individual, long assumed to be the ultimate repository of rights and values, is being reduced to a sum of group identities and an abstract matrix of rules. The irony for Seligman is that, in becoming postmodern, we seem to be moving backward to a premodern condition in which group sanctions rather than trust are the basis of group life. (shrink)

Discusses recent work on representationalism, including: the case for a representationalist theory of consciousness, which explains consciousness in terms of content; rivals such as neurobiological type-type identity theory (Papineau, McLaughlin) and naive realism (Allen, Campbell, Brewer); John Campbell and David Papineau's recent objections to representationalism; the problem of the "laws of appearance"; externalist vs internalist versions of representationalism; the relation between representationalism and the mind-body problem.
