In the pure powers ontology (PPO), basic physical properties have wholly dispositional essences. PPO has clear advantages over categoricalist ontologies, which suffer from familiar epistemological and metaphysical problems. However, opponents argue that because it contains no qualitative properties, PPO lacks the resources to individuate powers, and generates a regress. The challenge for those who take such arguments seriously is to introduce qualitative properties without reintroducing the problems that PPO was meant to solve. In this paper, I distinguish the core claim (...) of PPO: (i) basic physical properties have dispositional essences, from a hitherto unnoticed assumption: (ii) the dispositional essences of basic physical properties exclusively involve type-causal relations to other basic physical properties. I reject (ii), making room for a structuralist ontology in which all basic physical properties are pure powers, individuated by their places in a causal structure that includes not only other powers, but also physically realized qualitative properties such as shapes, patterns and structures. Such qualities individuate pure powers in the way that non-mental input and output properties individuate realized mental properties in functionalist theories of mind, except that here it is basic physical powers that are individuated by relations to realized non-powers. I distinguish one Platonic and two Aristotelian version of this theory, and argue that the Aristotelian versions require that grounding is not always a relative fundamentality relation, because the powers ground the qualities that individuate them. By considering ontic structural realism, I argue that symmetric grounding is the best way to make sense of relational individuation in structuralist ontologies, and is therefore no additional commitment of the one proposed here.

The recent literature on mental causation has not been kind to nonreductive, materialist functionalism (‘functionalism’, hereafter, except where that term is otherwise qualified). The exclusion problem2 has done much of the damage, but the epiphenomenalist threat has taken other forms. Functionalism also faces what I will call the ‘problem of metaphysically necessary effects’ (Block, 1990, pp. 157-60, Antony and Levine, 1997, pp. 91-92, Pereboom, 2002, p. 515, Millikan, 1999, p. 47, Jackson, 1998, pp. 660-61). Functionalist mental properties (...) are individuated partly by their relation to the very effects those properties’ instantiations are thought to cause. Consequently, functionalist causal generalizations would seem to have the following problematical structure: The state of being, among other things, a cause of e (under such-andsuch conditions) causes e (under those conditions).3 The connection asserted lacks the contingency one would expect of a causal generalization. Mental states of the kind in question are, by metaphysical necessity, causes of e; any state that does not cause e is thereby a different kind of state. Yet, a mental state’s being the sort of state it is must play some causal role if functionalism is to account for mental causation.4 In what follows, I first articulate more fully the problem of metaphysically necessary effects. I then criticize three functionalist attempts to solve the problem directly. Given the failure of functionalist efforts to meet the problem head-on, I consider less direct strategies: these involve formulating functionalism or its causal claims in such a way that they appear not to generate the problem of metaphysically necessary effects. I argue against these indirect solutions, in each case concluding either that the problem still arises or that avoiding it requires the adoption of an unorthodox form of functionalism (itself a surprising result). In the final.. (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)

The independence problems for functionalism stem from the worry that if functional properties are defined in terms of their causes and effects then such functional properties seem to be too intimately connected to these purported causes and effects. I distinguish three different ways the independence problems can be filled out – in terms of necessary connections, analytic connections and vacuous explanations. I argue that none of these present serious problems. Instead, they bring out some important and over-looked features of (...) functionalism. (shrink)

This paper demonstrates that there is an inconsistency in functionalism in psychology and philosophy of mind. Analogous inconsistencies can be expected in functionalisms in biology and social theory. (edited).

In her 2007 paper, “Argument Has No Function” Jean Goodwin takes exception with what she calls the “explicit function claims”, arguing that not only are function-based accounts of argumentation insufficiently motivated, but they fail to ground claims to normativity. In this paper I stake out the beginnings of a functionalist answer to Goodwin.

It is argued that although George Bealer's influential ‘Self-Consciousness argument’ refutes standard versions of reductive functionalism (RF), it fails to generalize in the way Bealer supposes. To wit, he presupposes that any version of RF must take the content of ‘pain’ to be the property of being in pain (and so on), which is expressly rejected in independently motivated versions of conceptual role semantics (CRS). Accordingly, there are independently motivated versions of RF, incorporating CRS, which avoid Bealer's main type (...) of refutation. I focus particularly on one such theory, which takes concepts to be event types that are individuated by their psychological roles, which has the resources of responding to each of the more specific worries Bealer expresses.

Functionalist theories have been proposed for just about everything: mental states, dispositions, moral properties, truth, causation, and much else. The time has come for a functionalist theory of nothing. Or, more accurately, a role functionalist theory of those absences that are causes and effects.

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’ answ...

How should ‘the physical’ be defined for the purpose of formulating physicalism? In this paper I defend a version of the via negativa according to which a property is physical just in case it is neither fundamentally mental nor possibly realized by a fundamentally mental property. The guiding idea is that physicalism requires functionalism, and thus that being a type identity theorist requires being a realizer-functionalist. In §1 I motivate my approach partly by arguing against Jessica Wilson's no fundamental (...) mentality constraint. In §2 I set out my preferred definition of ‘the physical’ and make my case that physicalism requires functionalism. In §3 I defend my proposal by attacking the leading alternative account of ‘the physical,’ the theory-based conception. Finally, in §4 I draw on my definition, together with Jaegwon Kim's account of intertheoretic reduction, to defend the controversial view that physicalism requires a priori physicalism. (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)

Philosophers almost universally believe that concepts of supervenience fail to satisfy the standards for physicalism because they offer mere property correlations that are left unexplained. They are thus compatible with non-physicalist accounts of those relations. Moreover, many philosophers not only prefer some kind of functional-role theory as a physically acceptable account of mind-body and other inter-level relations, but they use it as a form of “superdupervenience” to explain supervenience in a physically acceptable way. But I reject a central part of (...) this common narrative. I argue that functional-role theories fail by the same standards for physicalism because they merely state without explaining how a physical property plays or occupies a functional role. They are thus compatible with non-physicalist accounts of that role-occupying relation. I also argue that one cannot redeploy functional-role theory at a deeper level to explain role occupation, specifically by iterating the role-occupant scheme. Instead, one must use part-whole structural and mechanistic explanations that differ from functional-role theory in important ways. These explanations represent a form of “superduperfunctionalism” that stand to functional-role theory as concepts of superdupervenience stand to concepts of supervenience. (shrink)

According to proper functionalist theories of warrant, a belief is warranted only if it is formed by cognitive faculties that are properly functioning according to a good, truth-aimed design plan, one that is often thought to be specified either by intentional design or by natural selection. A formidable challenge to proper functionalist theories is the Swampman objection, according to which there are scenarios involving creatures who have warranted beliefs but whose cognitive faculties are not properly functioning, or are poorly designed, (...) or are not aimed at truth. In this paper, we draw lessons from cognitive science in order to develop a novel argument for the conclusion that the Swampman objection fails against proper functionalist theories of warrant. Our argument not only shows that the underlying, central intuition motivating Swampman-like scenarios is false but also motivates proper function as a necessary condition for warrant, thereby lending support to the claim that any theory of knowledge that lacks a proper function requirement is false.

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)

I argue that Stich's Syntactic Theory of Mind (STM) and a naturalistic narrow content functionalism run on a Language of Though story have the same exact structure. I elaborate on the argument that narrow content functionalism is either irremediably holistic in a rather destructive sense, or else doesn't have the resources for individuating contents interpersonally. So I show that, contrary to his own advertisement, Stich's STM has exactly the same problems (like holism, vagueness, observer-relativity, etc.) that he claims (...) plague content-based psychologies. So STM can't be any better than the Representational Theory of Mind (RTM) in its prospects for forming the foundations of a scientifically respectable psychology, whether or not RTM has the problems that Stich claims it does.

Functionalism about truth, or alethic functionalism, is one of our most promising approaches to the study of truth. In this chapter, I chart a course for functionalist inquiry that centrally involves the empirical study of ordinary thought about truth. In doing so, I review some existing empirical data on the ways in which we think about truth and offer suggestions for future work on this issue. I also argue that some of our data lend support to two kinds (...) of pluralism regarding ordinary thought about truth. These pluralist views, as I show, can be straightforwardly integrated into the broader functionalist framework. The main result of this integration is that some unexplored metaphysical views about truth become visible. To close the chapter, I briefly respond to one of the most serious objections to functionalism, due to Cory Wright. (shrink)

I argue that there is a flaw in the way that response-dependence has been formulated in the literature, and this flawed formulation has been correctly attacked by Mark Johnston’s Missing Explanation Argument (1993, 1998). Moving to a better formulation, which is analogous to the move from behaviourism to functionalism, avoids the Missing Explanation Argument.

Spacetime functionalism is the view that spacetime is a functional structure implemented by a more fundamental ontology. Lam and Wüthrich have recently argued that spacetime functionalism helps to solve the epistemological problem of empirical coherence in quantum gravity and suggested that it also (dis)solves the hard problem of spacetime, namely the problem of offering a picture consistent with the emergence of spacetime from a non-spatio-temporal structure. First, I will deny that spacetime functionalism solves the hard problem by (...) showing that it comes in various species, each entailing a different attitude towards, or answer to, the hard problem. Second, I will argue that the existence of an explanatory gap, which grounds the hard problem, has not been correctly taken into account in the literature. (shrink)

Christian Quast has recently embarked on the project of systematizing the debate about the notion of expertise, an extremely fascinating and important issue addressed by scholars of many disciplines yet still in need of an interdisciplinary take. He sheds light on a number of relevant features of this notion and defends what he calls a “balanced” account of expertise, namely one that defines this concept in light of an expert’s dispositions, manifestations of their dispositions, and social role or function. In (...) this critical reply, I offer some considerations that put pressure on Quast’s balanced account and hopefully help anyone interested in this debate take a step forward toward explaining what it takes for one to be an expert. The reply is structured as follows. First, I argue that his allegedly balanced view is liable to a potentially compromising tension between its function component and the ingredients of objective expertise (§1). Then, I show that Quast’s threefold characterization of an objective expert is too strong, as it imposes conditions that several individuals whom we would consider experts are unable to fulfill (§2). Finally, I provide reasons in favor of endorsing an objective account of expertise in light of some specific features of our society and show how this account can take into due consideration the different services experts ordinarily perform (§3).

Eleanor Knox has argued that our concept of spacetime applies to whichever structure plays a certain functional role in the laws (the role of determining local inertial structure). I raise two complications for this approach. First, our spacetime concept seems to have the structure of a cluster concept, which means that Knox's inertial criteria for spacetime cannot succeed with complete generality. Second, the notion of metaphysical fundamentality may feature in the spacetime concept, in which case spacetime functionalism may be (...) uninformative in the absence of answers to fundamental metaphysical questions like the substantivalist/relationist debate.

We commonly say that some evidence supports a hypothesis or that some premise evidentially supports a conclusion. Both internalists and externalists attempt to analyze this notion of evidential support, and the primary purpose of this paper is to argue that reliabilist and proper functionalist accounts of this relation fail. Since evidential support is one component of inferential justification, the upshot of this failure is that their accounts of inferential justification also fail. In Sect. 2, I clarify the evidential support relation. (...) In Sects. 3–5, I subject reliabilist and proper functionalist accounts of evidential support to various counterexamples. In Sect. 6, I show that the most promising ways to address these counterexamples aren’t very promising. (shrink)

This paper considers two issues raised by the claim that fictional characters are abstract artifacts. First, given that artifacts normally have functions, what is the function of a fictional character? Second, given that, in experiencing works of fictions, we usually treat fictional characters as concrete individuals, how can such a phenomenology fit with an ontology according to which fictional characters are abstract artifacts? I will indirectly address the second issue by directly addressing the first one. For this purpose, I will (...) rely on the notion of a mental file. I will argue that the function of fictional characters is the generation of mental files of a special kind. I will show that our experience of fictional characters as concrete individuals depends on the kind of mental files that are generated by fictional characters as abstract artifacts. I will conclude that an appreciator of a work of fiction can open two files about a certain fictional character; one about the character as an individual in the fictional world, and the other about the character as an abstract artifact in the actual world. In this sense, our relation to a fictional character is characterized by a duality of files or ‘twofileness’. (shrink)

The Hypothesis of Extended Cognition (HEC) holds that that not all human cognition is realized inside the head. The related but distinct Hypothesis of Extended Mentality (HEM) holds that not all human mental items are realized inside the head. Clark & Chalmers distinguish between these hypotheses in their original treatment of cognitive extension, yet these two claims are often confused. I distinguish between functionalist theories on which functional roles are individuated according to computational criteria, and those on which functional roles (...) are individuated according to rational criteria. I then present an argument for a modest version of HEC from computational functionalism, based on Clark & Chalmers’ original argument. In doing so I articulate a successor to their parity principle, and review studies by Wayne Gray et al. that provide plausible evidence for actual cognitive extension. I then respond to a new criticism of HEC by Mark Sprevak using the modest account I have developed, arguing that Sprevak conflates HEC and HEM. (shrink)

How or in virtue of what does any one particular action differ from another? Available views on the issue of action individuation tend to emphasize the descriptive features of actions, such as where and when they occur, or what they cause or are caused by. I contend instead that actions are individuated by their normative features, such as what licenses them and what they license in turn. In this essay, deploying a suggestion from Sellars and Brandom, I argue specifically that (...) actions are individuated by their normative function or role. (shrink)

A very common view of Hume’s distinction between impressions and ideas is that it is based on their intrinsic properties; specifically, their force and vivacity. Some interpreters have challenged this,one being David Landy (Landy 2006). He argues that for Hume the difference lies instead in the fact that impressions are not copies of anything, while ideas are copies of impressions. I regard this view as unsatisfactory, not because it is fundamentally mistaken but because (to put it in Humean terms) it (...) “…it discovers not all the truth” (Treatise 1.3.7.4). I will argue that Hume was a functionalist about (some)mental kinds, individuating impressions, ideas, and beliefs (and possibly other mental phenomena) in terms of their causal role in our mental economy. The distinction between impressions and ideas involves the fact that ideas are copies and impressions are not, but also more than that. I will also argue that interpreting Hume as a functionalist enables one to make sense of a passage that is impossible to explain on the force-and-vivacity view, and that it does so more readily than Landy’s view.Furthermore, I think this interpretation makes better sense of Hume’s “missing shade of blue” than Landy’s does.

Interview with professor Robert D Rupert.

This chapter argues that Simon anticipated what has emerged as the consensus view about human cognition: embodied functionalism. According to embodied functionalism, cognitive processes appear at a distinctively cognitive level; types of cognitive processes (such as proving a theorem) are not identical to kinds of neural processes, because the former can take various physical forms in various individual thinkers. Nevertheless, the distinctive characteristics of such processes — their causal structures — are determined by fine-grained properties shared by various, (...) often especially bodily related, physical processes that realize them. Simon’s apparently anti-embodiment views are surveyed and are shown to be consistent with his many claims that lend themselves to an embodied interpretation and that, to a significant extent, helped to lay the groundwork for an embodied cognitive science.

A theory of truth is an explanation of the nature of truth and set of rules that true things obey. A theory of truth is basically an attempt to enlighten on the nature of truth and formulate a set of laws that ‘true’ things follow. When we recall a memory, or analyze a statement, or appeal to evaluate within our brain, in fact, we are in quest for truth. Different theories of truth try to understand it from different perspectives. Attempts (...) to analyze truth down the history can neatly be divided into two: Classical and Contemporary theories. The classical or otherwise known as the traditional theories of truth are, Correspondence theory, Coherence theory, Pragmatic theory. Contemporary theories or otherwise known as modern theories of truth are mostly deflationary theories. Over and above these two categories we shall discuss a new theory of truth known as Functional theory of truth. When we analyze contemporary theories of truth, such as functionalist theory of truth, specifically alethic pluralism which commits the problem of mixed compound and also suggest the solution for the same.

Many prominent conceptions of moral progress implicitly assume that progress must lead to convergence in the moral domain. However, given the actual plurality of ways of life and attendant moral outlooks, there is no reason to assume improvement must lead to uniformity. Moreover, as the entanglement of the Enlightenment discourse of progress with colonialism makes evident, the assumption that progress must lead to convergence can license problematic practical conclusions. Drawing on insights from postcolonialist critique, I argue in favor of functionalist (...) conceptions of moral progress. Functionalist conceptions of moral progress do not assume that progress must lead to convergence. By contrast, they make it possible to understand progress in a pluralistic way. Functionalist conceptions of moral progress thus offer one way to develop a conception of moral progress, which can offer practical guidance, while taking into account one important line of critique of the discourse of progress.

In this essay, I argue that Sartre's notion of pre-reflective consciousness can be summoned to offer a general challenge to contemporary functionalist accounts of mind, broadly construed. In virtue of the challenge Sartre offers these contemporary functionalist accounts and the richness of his phenomenological analysis, I conclude that his voice needs to be included in ongoing debates over the nature of consciousness. First, I look at some of the basic claims motivating functionalist accounts of mind. Next, I look at Sartre's (...) notion of pre-reflective consciousness and discuss how this notion challenges functionalist accounts of mentality. I conclude by suggesting that Sartre's rendering of pre-reflective consciousness remains overly cognitivist. I show how this notion can be deepened to include the sensory-motor capacities of the situated body—resulting in a pre-reflective bodily self-awareness—and how this deepened formulation offers a further challenge to functionalist accounts of mind.

Alethic functionalism, as propounded by Michael Lynch, is the view that there are different ways to be true, but that these differences nevertheless contain enough unity to forestall outright pluralism. This view has many virtues. Yet, since one could conceivably apply Lynch’s “one and many” strategy to other debates, I try to show how his argumentative steps can be used to solve — not just the controversy pertaining to truth — but any controversy that surrounds a “What is X?” (...) question.

The term ‘functionalism’ is usually heard in connection with the philosophy of mind or cognition. The functionalism of Wilfrid Sellars, however, is in the first instance as response to the worries about the metaphysics not of mental states, but of meaning. Only late in his career did Sellars explore the possibility of extending his functionalism into an account of cognition. It has been suggested, though, that Sellars’ extension of his functionalist theory into subpersonal territory is not successful. (...) In particular, there is a worry abroad that in order to be a functionalist about cognitive states, Sellars must succumb to a special form of the Myth of the Given. In this essay I will review and elucidate what I take to be the structure of Sellars’ functionalism, defending it from this worry. I will suggest a resolution of some apparent textual contradictions based in part on the chronology of Sellars’ writing, with the assumption that later writings express Sellars’ more nuanced views. -/- Draft of 2009.

As British and American idealism waned, new realisms displaced them. The common background of these new realisms emphasized the problem of the external world and the mind-body problem, as bequeathed by Reid, Hamilton, and Mill. During this same period, academics on both sides of the Atlantic recognized that the natural sciences were making great strides. Responses varied. In the United States, philosophical response focused particularly on functional psychology and Darwinian adaptedness. This article examines differing versions of that response in William (...) James and Roy Wood Sellars. James viewed the mind as a “fighter for ends.” His neutral monism, by taming the mind-body problem and the problem of the external world, provided a secure metaphysics of mind as functional activity. In contrast, Sellars ’s scientific realism endorsed physical reality but was not mechanistic or reductionist. His critical realism and evolutionary naturalism offered novel metaphysical and epistemological positions in comparison with other American and British realisms. James and Sellars are distinguished from British philosophy in 1890–1918 in the types of realism they endorsed and in their success at introducing Darwinian evolutionary considerations and functional psychology into mainstream philosophy.

Chalmers (2002) argues against physicalism in part using the premise that no truth about consciousness can be deduced a priori from any set of purely structural truths. Chalmers (2012) elaborates a detailed definition of what it is for a truth to be structural, which turns out to include spatiotemporal truths. But Chalmers (2012) then proposes to define spatiotemporal terms by reference to their role in causing spatial and temporal experiences. Stoljar (2015) and Ebbers (Ms) argue that this definition of spatiotemporal (...) terms allows for the trivial falsification of Chalmers (2002)’s premise about structure and consciousness. I show that this result can be avoided by tweaking the relevant premise, and moreover that this tweak is well-motivated and not ad hoc. (shrink)

In this chapter I argue that there is such a barrier created by self-conscious intentional states—conscious intentional states that are about one’s own conscious intentional states. As we will see, however, this result is entirely compatible with a scientific theory of mind, and, in fact, there is an elegant non-reductive framework in which just such a theory may be pursued.

The world is occupied by many and varied things. What constitutes their thingness? In the Essay, Locke addresses this question in Book II, Chapter xxiii, titled ‘Of our Complex Ideas of Substance’, wherein the much-contested definition of ‘substratum’ appears—‘a supposed but unknown support of the Qualities’. Most significant in this definition are the dual qualifiers that Locke uses: ‘supposed’ and ‘unknown’. This paper examines this two-qualifier definition, illuminating the historical and philosophical significance it may have. There have been two rival (...) readings. The first takes Locke’s substratum to be a bare substratum; and the second identifies it with what Locke terms as ‘real essence’—i.e. ‘a real Constitution of the insensible Parts’. Critically reviewing these two major interpretations, I attribute to Locke a type of functionalism, according to which the status of a substratum is determined by its functional role of ‘uniting’ a bundle of qualities into an individual substance.

In the article I discuss functionalist interpretations of Husserlian phenomenology. The first one was coined in the discussion between Hubert Dreyfus and Ronald McIntyre. They argue that Husserl’s phenomenology shares similarities with computational functionalism, and the key similarity is between the concept of noema and the concept of mental representation. I show the weaknesses of that reading and argue that there is another available functionalist reading of Husserlian phenomenology. I propose to shift perspective and approach the relation between phenomenology (...) and functionalism from a methodological perspective, specifically taking into account the functionalist explanatory strategy called functional analysis. I discuss the notion of function in Husserl’s works and Husserl’s idea of functional phenomenology. The key argument I develop is that in functional phenomenology we can find an explanatory strategy which is analogous to the strategy of functional decomposition used in functional analysis. I conclude that the proposed functionalist reading of phenomenology opens a new approach to the integration of phenomenology with cognitive sciences. (shrink)

The viewpoint that consciousness, including feeling, could be fully expressed by a computational device is known as strong artificial intelligence or strong AI.

Philosophers have argued that on the prevailing theory of mind, functionalism, the fact that mental states are multiply realizable or can be instantiated in a variety of different physical forms, at least in principle, shows that materialism or physical is probably false. A similar argument rejects the relevance to psychology of connectionism, which holds that mental states are embodied and and constituted by connectionist neural networks. These arguments, I argue, fall before reductios ad absurdam, proving too much -- they (...) apply as well to genes, which are multiply realizable, but the reduction of which to DNA is one the core cases of scientific reductive explanation, a reduction if anything is. -/- I suggest that psychology, like biology, be what I call "provincialized," abandon claims to universal validity, except as an idealization, and treat different classes of cognizers differently from an an explanatory perspective. This would permit specifies specific, or more precisely, provincial reductions of different psychologies that might be multiply realized if such reductions were available. Connectionism may be the foundation of a reduction of human psychology, and thus biology and connectionism retain their relevance to psychology, and physicalism or materialism is consistent with functionalism.

Functionalism would be mistaken if there existed a system of deviant relations (an “anti-mind”) that had the same functional roles as the standard mental relations. In this paper such a system is constructed, using “Quinean transformations” of the sort associated with Quine’s thesis of the indeterminacy of translation. For example, a mapping m from particularistic propositions (e.g., that there exists a rabbit) to universalistic propositions (that rabbithood is manifested). Using m, a deviant relation thinking* is defined: x thinks* p (...) iff x thinks m(p). Such deviant relations satisfy the commonly discussed functionalist psychological principles. Finally, a more complicated system of deviant relations is constructed, one satisfying sophisticated principles dealing with the self-conscious rational mind. (shrink)

The functionalist approach to kinds has suffered recently due to its association with law-based approaches to induction and explanation. Philosophers of science increasingly view nomological approaches as inappropriate for the special sciences like psychology and biology, which has led to a surge of interest in approaches to natural kinds that are more obviously compatible with mechanistic and model-based methods, especially homeostatic property cluster theory. But can the functionalist approach to kinds be weaned off its dependency on laws? Dan Weiskopf has (...) recently offered a reboot of the functionalist program by replacing its nomological commitments with a model-based approach more closely derived from practice in psychology. Roughly, Weiskopf holds that the natural kinds of psychology will be the functional properties that feature in many empirically successful cognitive models, and that those properties need not be localized to parts of an underlying mechanism. I here skeptically examine the three modeling practices that Weiskopf thinks introduce such non-localizable properties: fictionalization, reification, and functional abstraction. In each case, I argue that recognizing functional properties introduced by these practices as autonomous kinds comes at clear cost to those explanations’ counterfactual explanatory power. At each step, a tempting functionalist response is parochialism: to hold that the false or omitted counterfactuals fall outside the modeler’s explanatory aims, and so should not be counted against functional kinds. I conclude by noting the dangers this attitude poses to scientific disagreement, inviting functionalists to better articulate how the individuation conditions for functional kinds might outstrip the perspective of a single modeler.

Functionalism is often used to identify mental states with physical states. A particularly powerful case is Lewis's analytical functionalism. Kripke's view seriously challenges any such identification. The dispute between Kripke and Lewis's views boils down to whether the term ‘pain’ is rigid or nonrigid. It is a strong intuition of ours that if it feels like pain it is pain, and vice versa, so that ‘pain’ should designate, with respect to every possible world, all and only states felt (...) as pain. Hence, in order to settle the dispute, we need to check which of the two – Kripke's use of ‘pain’ as rigid, or Lewis's use of ‘pain’ as nonrigid – better meets this intuition. I show that, despite crucial differences in both their semantic and metaphysical assumptions, surprisingly, both views meet this intuition equally well. Thus it appears that this question of rigidity cannot, in principle, be solved, and so, at least with respect to this particular dispute, the jury is still out on whether mental states are identical to physical states.

Functionalism of robot pain claims that what is definitive of robot pain is functional role, defined as the causal relations pain has to noxious stimuli, behavior and other subjective states. Here, I propose that the only way to theorize role-functionalism of robot pain is in terms of type-identity theory. I argue that what makes a state pain for a neuro-robot at a time is the functional role it has in the robot at the time, and this state is (...) type identical to a specific circuit state. Support from an experimental study shows that if the neural network that controls a robot includes a specific 'emotion circuit', physical damage to the robot will cause the disposition to avoid movement, thereby enhancing fitness, compared to robots without the circuit. Thus, pain for a robot at a time is type identical to a specific circuit state. (shrink)

Ontological functionalism's defining tenet is that mental properties can be defined wholly in terms of the general pattern of interaction of ontologically prior realizations. Ideological functionalism's defining tenet is that mental properties can only be defined nonreductively, in terms of the general pattern of their interaction with one another. My Self-consciousness Argument establishes: ontological functionalism is mistaken because its proposed definitions wrongly admit realizations into the contents of self-consciousness; ideological functionalism is the only viable alternative for (...) functionalists. Michael Tooley's critique misses the target: he offers no criticism of - except for an incidental, and incorrect, attack on certain self-intimation principles - and, since he himself proposes a certain form of nonreductive definition, he tacitly accepts. Finally, as with all other nonreductive definitions, Tooley's proposal can be shown to undermine functionalism's ultimate goal: its celebrated materialist solution to the Mind-Body Problem. The explanation of these points will require a discussion of: Frege-Russell disagreements regarding intensional contexts; the relationship between self-consciousness and the traditional doctrine of acquaintance; the role of self-intimation principles in functionalist psychology; and the Kripke-Lewis controversy over the nature of theoretical terms.

Traditional inflationary approaches that specify the nature of truth are attractive in certain ways; yet, while many of these theories successfully explain why propositions in certain domains of discourse are true, they fail to adequately specify the nature of truth because they run up against counterexamples when attempting to generalize across all domains. One popular consequence is skepticism about the efficaciousness of inflationary approaches altogether. Yet, by recognizing that the failure to explain the truth of disparate propositions often stems from (...) inflationary approaches' allegiance to alethic monism, pluralist approaches are able to avoid this explanatory inadequacy and the resulting skepticism, though at the cost of inviting other conceptual difficulties. A novel approach, alethic functionalism, attempts to circumvent the problems faced by pluralist approaches while preserving their main insights. Unfortunately, it too generates additional problems---namely, with its suspect appropriation of the multiple realizability paradigm and its platitude-based strategy---that need to be dissolved before it can constitute an adequate inflationary approach to the nature of truth.

Self-consciousness constitutes an insurmountable obstacle to functionalism. Either the standard functional definitions of mental relations wrongly require the contents of self-consciousness to be propositions involving “realizations” rather than mental properties and relations themselves. Or else these definitions are circular. The only way to save functional definitions is to expunge the standard functionalist requirement that mental properties be second-order and to accept that they are first-order. But even the resulting “ideological” functionalism, which aims only at conceptual clarification, fails unless (...) it incorporates the thesis that the mental properties are fully “natural” universals. Accordingly, mental properties are sui generis: first-order, nonphysical, natural universals. (shrink)
