One job for theories of mental representation is to distinguish between different kinds of mental representation: beliefs, desires, intentions, perceptual states, etc. What makes a mental state a belief that p rather than a desire that p or a visual representation that p? Functionalism is a leading approach for doing so: for individuating mental states. Functionalism is designed to allow that psychological states can be multiply realized. Mark Sprevak has argued that, for a functionalist account of psychological states (...) to apply to creatures that are organised in a very different way to humans (call them Martians), the way a psychological state is functionally individuated has to be relatively coarse-grained (Sprevak 2009). Psychological research might show that human beliefs are directly available to consciousness, that they are formed as the result of deliberate judgement, and so on, but theorists would be precluded from including these roles in their account of belief, if Sprevak is right. The argument for coarse-grained individuation fails if we distinguish functionalism about what it takes to be a psychological state in general from functionalism about a particular state type such as belief. Functionalism individuates a psychological state like believing that p partly by reference to its relations to other psychological states: desiring that p, perceiving that p, intending that p, etc. Functionalist motivations do indeed suggest that Martians with a functional organisation and physical substrate quite unlike humans could have psychological states, but not that they should have states with the interrelated collection of functional roles to count as beliefs, desires, intentions, etc. Thus, theorists are not precluded from including functional relations to consciousness or deliberate judgement in their account of (human) belief, consistent with allowing that Martians would have their own collection of functionally interrelated psychological states. Sprevak’s coarse-grained functionalism implies an implausibly liberal form of extended cognition. The point about functional interrelations allows us to avoid that conclusion without jettisoning functionalism (as Sprevak suggests we should): records in a human notebook may not enter into the right interrelations with other human psychological states to count as beliefs; nor do they enter into any interrelations with Martian psychological states. Functionalism can therefore allow that Martians have psychological states while holding that few if any of the beliefs we humans have are, as a matter of fact, extended. (shrink)

Should economics study the psychological basis of agents' choice behaviour? I show how this question is multifaceted and profoundly ambiguous. There is no sharp distinction between "mentalist'' answers to this question and rival "behavioural'' answers. What's more, clarifying this point raises problems for mentalists of the "functionalist'' variety (Dietrich and List, 2016). Firstly, functionalist hypotheses collapse into hypotheses about input--output dispositions, I show, unless one places some unwelcome restrictions on what counts as a cognitive variable. Secondly, functionalist hypotheses make some (...) risky commitments about the plasticity of agents' choice dispositions. (shrink)

The paper argues that a broadly functionalist picture of psychological phenomena is quite consistent with at least one interesting thesis of psychological reductionism.

An introduction to functionalism in the philosophy of psychology/mind, and review of the current state of debate pro and con. Forthcoming in the Routledge Companion to the Philosophy of Psychology (John Symons and Paco Calvo, eds.).

The paper links Freud’s early work in the ‘Project for a scientific psychology’ with the psychoanalytic psychology of Kleinian object relations theory now current. Freud is often accused of introducing mechanism into his psychology and installing at its core an irreconcilable dichotomy of two disparate ways of explaining human behaviour. I suggest that Freud’s early mechanistic thinking is an attempt at what he only partly achieves, a functional account of the ‘mental apparatus’. I consider whether this way (...) of conceptualising the mind in functional terms is methodologically relevant to psychoanalytic investigation or whether it is at best heuristically useful. From a brief consideration of Kleinian object relations theory, illustrated by case material, I conclude that there are grounds for accepting the first of these alternatives. (shrink)

Inferences are familiar movements of thought, but despite important recent work on the topic, we do not yet have a fully satisfying theory of inference. Here I provide a functionalist theory of inference. I argue that the functionalist framework allows us the flexibility to meet various demands on a theory of inference that have been proposed (such as that it must explain inferential Moorean phenomena and epistemological ‘taking’). While also allowing us to compare, contrast, adapt, and combine features of extant (...) theories of inference into one unified theory. In fleshing out the inference role, I also criticize the common assumption that inference requires rule-following. (shrink)

Functionalism, a philosophical theory, has empirical consequences. Functionalism predicts that where systematic transformations of sensory input occur and are followed by behavioral accommodation in which normal function of the organism is restored such that the causes and effects of the subject's psychological states return to those of the period prior to the transformation, there will be a return of qualia or subjective experiences to those present prior to the transform. A transformation of this type that has long been (...) of philosophical interest is the possibility of an inverted spectrum. Hilary Putnam argues that the physical possibility of acquired spectrum inversion refutes functionalism. I argue, however, that in the absence of empirical results no a priori arguments against functionalism, such as Putnam's, can be cogent. I sketch an experimental situation which would produce acquired spectrum inversion. The mere existence of qualia inversion would constitute no refutation of functionalism; only its persistence after behavioral accommodation to the inversion would properly count against functionalism. The cumulative empirical evidence from experiments on image inversion suggests that the results of actual spectrum inversion would confirm rather than refute functionalism. (shrink)

David Lewis's position, often called analytic functionalism, was inspired by Ryle's analytic behaviorism, which took psychological predicates to express complex sets of behavioral dispositions. In this chapter, the author reviews some tenets of Lewis's philosophy of mind and begins with some comments on the methodology Lewis employed in his analysis of psychological terms, which has become standard in functionalist accounts across philosophy. Then, he discusses the difference between what are often called “realizer functionalism” and “role functionalism,” and (...) argues that Lewis made the wrong choice. In Lewis's argument for the identity theory, the identity of mental states with biological states follows logically from folk‐psychological definitions and broadly physical facts. A central part of folk psychology concerns the interaction of beliefs, desires, and choices. The chapter presents Lewis's often misunderstood account of intentionality. It also presents few pessimistic remarks on the prospect of analyzing phenomenal truths in terms of functional role. (shrink)

Some philosophers have conflated functionalism and computationalism. I reconstruct how this came about and uncover two assumptions that made the conflation possible. They are the assumptions that (i) psychological functional analyses are computational descriptions and (ii) everything may be described as performing computations. I argue that, if we want to improve our understanding of both the metaphysics of mental states and the functional relations between them, we should reject these assumptions.

Functionalism in the philosophy of mind is the doctrine that what makes something a mental state of a particular type does not depend on its internal constitution, but rather on the way it functions, or the role it plays, in the system of which it is a part. This doctrine is rooted in Aristotle's conception of the soul, and has antecedents in Hobbes's conception of the mind as a “calculating machine”, but it has become fully articulated (and popularly endorsed) (...) only in the last third of the 20th century. Though the term ‘functionalism’ is used to designate a variety of positions in a variety of other disciplines, including psychology, sociology, economics, and architecture, this entry focuses exclusively on functionalism as a philosophical thesis about the nature of mental states. (shrink)

What is Functionalism? Functionalism is one of the major proposals that have been offered as solutions to the mind/body problem. Solutions to the mind/body problem usually try to answer questions such as: What is the ultimate nature of the mental? At the most general level, what makes a mental state mental? Or more specifically, What do thoughts have in common in virtue of which they are thoughts? That is, what makes a thought a thought? What makes a pain (...) a pain? Cartesian Dualism said the ultimate nature of the mental was to be found in a special mental substance. Behaviorism identified mental states with behavioral dispositions; physicalism in its most influential version identifies mental states with brain states. Functionalism says that mental states are constituted by their causal relations to one another and to sensory inputs and behavioral outputs. Functionalism is one of the major theoretical developments of Twentieth Century analytic philosophy, and provides the conceptual underpinnings of much work in cognitive science. (shrink)

I want to explore what happens to two philosophical issues when we assume that the mind, a functional device, is to be understood by the same sort of functional analysis that guides biological investigation of other organismic systems and characteristics. The first problem area concerns the concept of rationality, its connection with reliability and reproductive success, and the status of rationality hypotheses in attribution of beliefs. It has been argued that ascribing beliefs to someone requires the assumption that that person (...) is rational. It also has been argued that evolutionary theory can account for the capacity we have for rational thought by appealing to the idea that rational methods for constructing beliefs are reliable and therefore represented a selected advantage. Both of these claims about rationality are critically examined. In the second part of the paper, I turn to some criticisms that have been advanced against "functionalist" solutions to the mind/body problem. These criticisms are defused when that doctrine is understood in terms of a Teleological (rather than a Turing Machine) notion of function. However, functionalism does not emerge totally unscathed. Voltaire's Dr. Pangloss saw everything in terms of its function and its perfect performance of its function. In the philosophy of mind, his influence lives on in the form of two ideas: (i) that we must possess rational methods for constructing beliefs, since our minds are the product of natural selection, and (ii) that psychological states and properties are individuated by their psychological functions. Contemporary biology provides the resources for avoiding Pangloss's wideeyed teleology in the study of adaptation. It is to be hoped that progress in psychology will loosen the grip of Panglossian assumptions in the study of mind. (shrink)

Given their physical realization, what causal work is left for functional properties to do? Humean solutions to the exclusion problem (e.g. overdetermination and difference-making) typically appeal to counterfactual and/or nomic relations between functional property-instances and behavioural effects, tacitly assuming that such relations suffice for causal work. Clarification of the notion of causal work, I argue, shows not only that such solutions don't work, but also reveals a novel solution to the exclusion problem based on the relations between dispositional properties at (...) different levels of mechanism, which involves three central claims: (i) the causal work of properties consists in grounding dispositions, (ii) functional properties are dispositions, and (iii) the dispositions of mechanisms are grounded in the dispositions of their components. Treating functional mental properties as dispositions of components in psychological mechanisms, I argue that such properties do the causal work of grounding agent-level dispositions. These dispositions, while ultimately grounded in the physical realizers of mental properties, are indirectly so grounded, through a hierarchy of grounding relations that extends upwards, of necessity, through the mental domain. (shrink)

Functionalism about truth is the view that truth is an explanatorily significant but multiply-realizable property. According to this view the properties that realize truth vary from domain to domain, but the property of truth is a single, higher-order, domain insensitive property. We argue that this view faces a challenge similar to the one that Jaegwon Kim laid out for the multiple realization thesis. The challenge is that the higher-order property of truth is equivalent to an explanatorily idle disjunction of (...) its realization bases. This consequence undermines the alethic functionalists’ non-deflationary ambitions. A plausible response to Kim’s argument fails to carry over to alethic functionalism on account of significant differences between alethic functionalism and psychological functionalism. Lynch’s revised view in his book Truth as One and Many ( 2009 ) fails to answer our challenge. The upshot is that, while mental functionalism may survive Kim’s argument, it mortally wounds functionalism about truth. (shrink)

I offer a philosophically well-motivated solution to a problem that George Bealer has identified, which he claims is fatal to functionalism. The problem is that there seems to be no way to generate a satisfactory Ramsey sentence of a psychological theory in which mental-state predicates occur within the scopes of mental-state predicates. My central claim is that the functional roles in terms of which a creature capable of self-consciousness identifies her own mental states must be roles that items could (...) play within creatures whose psychology is less complex than hers. (Bealer’s reply to this paper appears in the same issue of Mind & Language.). (shrink)

We argue that the causal account offered by analytic functionalism provides the best account of the folk psychological theory of mind, and that people ordinarily define mental states relative to the causal roles these states occupy in relation to environmental impingements, external behaviors, and other mental states. We present new empirical evidence, as well as review several key studies on mental state ascription to diverse types of entities such as robots, cyborgs, corporations and God, and explain how this evidence (...) supports a functional account. We also respond to two challenges to this view based on the embodiment hypothesis, or the claim that physical realizers matter over and above functional role, and qualia. In both cases we conclude that research to date best supports a functional account of ordinary mental state concepts. (shrink)

Lockean accounts of personal identity face a problem of too many thinkers arising from their denial that we are identical to our animals and the assumption that our animals can think. Sydney Shoemaker has responded to this problem by arguing that it is a consequence of functionalism that only things with psychological persistence conditions can have mental properties, and thus that animals cannot think. I discuss Shoemaker’s argument and demonstrate two ways in which it fails. Functionalism does not (...) rid the Lockean of the problem of too many thinkers. (shrink)

It is here argued that functionalist constraints on psychology do not preclude the applicability of classic forms of reduction and, therefore, do not support claims to a principled, or de jure, autonomy of psychology. In Part I, after isolating one minimal restriction any functionalist theory must impose on its categories, it is shown that any functionalism imposing an additional constraint of de facto autonomy must also be committed to a pure functionalist--that is, a computationalist--model for psychology. (...) Using an extended parallel to the reduction of Mendelian to molecular genetics, it is shown in Parts II and III that, contrary to the claims of Hilary Putnam and Jerry Fodor, there is no inconsistency between computational models and classical reductionism: neither plurality of physical realization nor plurality of function are inconsistent with reductionism as defended by Ernest Nagel. Employing the results of Part I, the conclusions of Parts II and III are generalized in Part IV to cover any version of functionalism whatsoever; thus, functionalism and reductionism are shown to be consistent. It is urged in conclusion that although a de facto form of autonomy is defensible, there are sound methodological grounds for unconditionally rejecting any principled version of the autonomy of psychology.

Functionalism, the philosophical theory that defines mental states in terms of their causal relations to stimuli, overt behaviour, and other inner mental states, has often been accused of being unable to account for the qualitative character of our experimential states. Many times such objections to functionalism take the form of conceivability arguments. One is asked to imagine situations where organisms who are in a functional state that is claimed to be a particular experience either have the qualitative character (...) of that experience altered or absent altogether. Many of these arguments are surprisingly advanced by materialist philosophers. I argue that if the conceivability arguments were successful against functionalism, then they would be successful against their alternative materialist views as well. So the conceivability arguments alone do not provide a good reason for materialists to abandon functionalism. I further argue that functionalism is best understood to be an empirical theory, and if it is so understood then the conceivability arguments have no force against it at all. A further consequence that emerges is that on an empirical functionalist view, qualia, if real, are properties in the domain of psychology. (shrink)

In his recent article "The Computational Model of the Mind and Philosophical Functionalism," Richard Double argues that there are some fairly forceful a priori arguments showing that Philosophical Functionalism cannot provide adequate explanations for phenomenal states, the nonphenomenal conscious states of common sense, and the theoretical states of cognitive psychology and linquistics. In this paper it is argued that none of Double's arguments are successful.

Functionalist accounts of blame have been rising in popularity. Proponents of the approach claim that, by defining blame in terms of its function or functions, their account has the advantage of being able to accommodate a wide range of attitudes and activities as blame; but their opponents question the extensional and explanatory adequacy of such accounts. This paper contributes to this burgeoning literature by presenting new challenges to the existing functionalist accounts. The fundamental problem, I shall argue, lies in the (...) fact that they all focus on using functions to define blame as a type of practice, but this strategy fails to pick out a unique moral-psychological type and does not offer a complete set of extension-determining criteria for the concept of blame. This amounts to a serious theoretical disadvantage. I consider various responses to the challenges throughout the paper, concluding that the best reply available to the functionalist theorist involves using functions to directly define blame tokens.

Sellars, Brandom, and McDowell (whom Maher aptly calls the “Pittsburgh School”) have tremendous influence on the current shape of the analytic tradition. Despite their differing views on philosophy of language, the philosophy of mind, philosophy of action, and epistemology, their shared application of ‘normative functionalism’ highlights important similarities in their approaches to the aforementioned disciplines. Normative functionalism interprets the ability to form judgments, possess concepts, rationally defend or be critical of judgments, and consequently act as an agent, as (...) largely guided by one’s responsiveness to norms. In this article, I argue for two related claims. First, I argue that the Pittsburgh School’s normative functionalism has germinated from the seed of Sellars’ ‘psychological nominalism’ and cannot be separated from it. Second, no philosophical question or approach can be free of competing claims as to the manner in which human beings think, communicate, act, and know. As a result, normative functionalism (insofar as it is a natural extension of psychological nominalism) is relevant to many philosophical disciplines, because it opposes nearly all the traditional views concerning how the human intellect comes into being and functionally operates.

Deep learning is a kind of machine learning which happens in a certain type of artificial neural networks called deep networks. Artificial deep networks, which exhibit many similarities with biological ones, have consistently shown human-like performance in many intelligent tasks. This poses the question whether this performance is caused by such similarities. After reviewing the structure and learning processes of artificial and biological neural networks, we outline two important reasons for the success of deep learning, namely the extraction of successively (...) higher level features and the multiple layer structure, which are closely related to each other. Then some indications about the framing of this heated debate are given. After that, an assessment of the value of artificial deep networks as models of the human brain is given from the similarity perspective of model representation. Finally, a new version of computational functionalism is proposed which addresses the specificity of deep neural computation better than classic, program based computational functionalism. (shrink)

This article offers an analysis of ecologist Charles Elton’s “functional” concept of the niche and of the notion of function implicitly associated with it. It does so in part by situating Elton’s niche concept within the broader context of the “functionalist-interactionist” approach to ecology he introduced, and in relation to his views on the relationship between ecology and evolution. This involves criticizing the common claim that Elton’s idea of species as fulfilling functional roles within ecological communities committed him to an (...) idea of communities as units of selection. While such a claim implicitly attributes to Elton an understanding of function along the lines of the selected-effects theory of function advocated by many biologists and philosophers of biology, Elton’s use of the niche concept, I maintain, involves an understanding of function more along the lines of alternative nonselectionist theories such as the causal-role, goal-contribution, and organizational theories. I also briefly discuss how ecologists after Elton also tend to have typically adopted a nonselectionist understanding of the function concept, similar to his. (shrink)

Functionalism about kinds is still the dominant style of thought in the special sciences, like economics, psychology, and biology. Generally construed, functionalism is the view that states or processes can be individuated based on what role they play rather than what they are constituted of or realized by. Recently, Weiskopf has posited a reformulation of functionalism on the model-based approach to explanation. We refer to this reformulation as ‘new functionalism’. In this paper, we seek to (...) defend new functionalism and to recast it in light of the concrete explanatory aims of the special sciences. In particular, we argue that the assessment of the explanatory legitimacy of a functional kind needs to take into account the explanatory purpose of the model in which the functional kind is employed. We aim at demonstrating this by appealing to model-based explanations from the social and behavioral sciences. Specifically, we focus on preferences and signals as functional kinds. Our argument is intended to have the double impact of deflecting criticisms against new functionalism from the perspective of mechanistic decomposition while also expanding the scope of new functionalism to encompass the social and behavioral sciences.

Stanisław Lem’s short story Are you there Mr. Jones?, first published in 1955, is set in a courtroom. The plaintiff is Cybernetics Company – a provider of prosthetics – and the defendant is Harry Jones, a race-car driver. It turns out that Mr. Jones, after a series of grave accidents, has had his entire body gradually replaced by prostheses. He is now deep in debt to the provider, Cybernetics Company, which consequently has sued him to reclaim their property. We aim (...) to show that this short story illustrates important philosophical questions concerning personal identity and persistence over time, and that Lem in fact anticipates several of the main insights of functionalism, later introduced by Putnam (1967) and today a main contender for a theory of the mind. If the identity of Mr. Jones is constituted solely by his prostheses’ functional role, i.e., their causal relations to input, output and other bodily and mental states, Lem here gives us an early example of causal-theoretical functionalism. This brings us to the next question, implicitly raised by Lem: Is functional identity sufficient for personal identity? Is Mr. Jones the same person as he was before replacing all his body parts? In court, Mr. Jones argues for his continued personhood by appealing to memories from the past. This suggests the view that his persistence as a person depends on some form of psychological continuity, and we will discuss how the case of Mr. Jones relates to views on personal identity. (shrink)

Sydney Shoemaker argues that the functionalist theory of mind entails a psychological-continuity view of personal identity, as well as providing a defense of that view against a crucial objection. I show that his view has surprising consequences, e.g. that no organism could have mental properties and that a thing's mental properties fail to supervene even weakly on its microstructure and surroundings. I then argue that the view founders on "fission" cases and rules out our being material things. Functionalism tells (...) us little if anything about personal identity. (shrink)

A general characterization of functionalist theories of mind is offered and a number of issues are discussed which allow for alternative versions of functionalism. Some issues, such as the distinction between the implicit definition and partial specification views are of a general nature, while others raise questions more specific to functionalism, such as whether the relation between psychological and physiological properties is one of identity or instantiation. Section II attempts to undermine several arguments which have been offered to (...) support the non-identity position. In the final section, the suggestions that the relevant notions of functional equivalence might be unpacked solely in terms of abstract automata features or entirely in terms of causal relations to nonintentionally characterized behavior are shown to be inadequate. (shrink)

Functionalism in the philosophy of mind rests on the claim that mental states are multiply realizable; mental states can be realized by or instantiated in a variety of distinct physical structures. To see them as multiply realizable we take mental states as causal roles rather than particular physical structures. As such, functionalism can be contrasted with metaphysical accounts which treat mental states as instances of a mental substance. Instead of puzzling over the relationship between mental and physical kinds, (...) functionalists understand our talk of minds as a way of describing the functions of bodies. The attraction of a functionalist position is obvious. It seems to solve the traditional problem of mind-body dualism, while simultaneously reconciling the apparent irreducibility of psychological discourse with a broadly physicalistic or materialistic ontology. (shrink)

It seems that we could be physically the same as we are now, only we would lack conscious awareness. If so, then nothing about our physical world is necessary for qualitative experience. However, a proper analysis of psychological functionalism eliminates this problem concerning the possibility of zombies. ‘Friends of absent qualia’ rely on an overly simple view of what counts as a functional analysis and of the function/structure distinction. The level of thought is not the only level at which (...) one might perform a functional analysis; all that is required for some description of a state to be functional is that it be defined in terms of its causal relations. Insofar as functionalism is not restricted to a higher level of analysis , then successful theories of consciousness should include whatever it is that makes those states have a qualitative character. (shrink)

One might expect functionalism to imply that personal identity is preserved through various operations on the brain, including transplantation. I argue that this is not clearly so even where the whole brain is transplanted. It is definitely not so in cases where only the cerebrum is transplanted, a conceivable kind of hemispherectomy, and even certain cases in which the brain is "gradually" replaced by an inorganic substitute. These results distinguish functionalism from other accounts taking what Eric T. Olson (...) calls the "Psychological Approach" to personal identity, enabling it to avoid some of his objections to them. (shrink)

Saying that psychological states are functional states, the functionalist claims more than that psychological states have functions. Rather, functionalism is the theory that psychological states are defined and constituted by their functions. On this view, what it is to be a psychological state of a certain sort just is and consists entirely of having a certain function. Anything that has that function in a suitable system would therefore be that psychological state. If storing information for later use is the (...) essential function of memory, then anything that has that function counts as a memory. Similarly, one might say that anything that traps or kills mice counts as a mouse trap. (shrink)

Before embarking upon the project of reformulating psychoanalysis in the 'scientific' terminology of cognitive science, we should first clearly define what psychoanalysis is about and what it is not about. Cognitive science is based upon a functionalistic philosophy of the mind. As a consequence such a project would require a functionalistic core theory of psychoanalysis. But Freud's claim of the therapeutic effect of psychoanalysis, attained through the rendering conscious of what is unconscious or the making personal of what is experienced (...) by the neurotic patient as impersonal, cannot be explained by a functionalistic theory of the mind We examine Freud's claim and conclude that there ought to be a philosophy of qualia at the core of psychoanalysis.

This paper defends a social functionalist interpretation, modeled on psychological functionalism, of the meanings of social facts. Social functionalism provides a better explanation of the possibility of interpreting other cultures than approaches that identify the meanings of social facts with either mental states or behavior. I support this claim through a functionalist reinterpretation of sociological accounts of the categories that identify them with their collective representations. Taking the category of causality as my example, I show that if we (...) define it instead in terms of its functional relations to moral rules, it becomes easier to recognize in other cultures.
