This paper examines Jaegwon Kim's Supervenience Argument (SA) against nonreductive physicalism, concentrating on Kim's response to two of the most important objections against the SA: First, the Overdetermination Argument, according to which Kim has no convincing argument against the possibility that mental causation might be a case of genuine or systematic overdetermination; second, the Generalization Argument, according to which the SA would entail that causation at any level gives way to causation at the next lower level, thereby leading to an (...) untenable all-encompassing epiphenomenalism. It is argued that as of yet, Kim has failed to develop a coherent overall position, since various moves he makes in response to these criticisms are strangely at odds with other parts of his philosophical position.

Jaegwon Kim’s influential exclusion argument attempts to demonstrate the inconsistency of nonreductive materialism in the philosophy of mind. Kim’s argument begins by showing that the three main theses of nonreductive materialism, plus two additional considerations, lead to a specific and familiar picture of mental causation. The exclusion argument can succeed only if, as Kim claims, this picture is not one of genuine causal overdetermination. Accordingly, one can resist Kim’s conclusion by denying this claim, maintaining instead that the effects of the (...) mental are always causally overdetermined. I call this strategy the ‘ overdetermination challenge’. One of the main aims of this paper is to show that the overdetermination challenge is the most appropriate response to Kim’s exclusion argument, at least in its latest form. I argue that Kim fails to adequately respond to the overdetermination challenge, thus failing to prevent his opponents from reasonably maintaining that the effects of the mental are always causally overdetermined. Interestingly, this discussion reveals a curious dialectical feature of Kim’s latest response to the overdetermination challenge: if it succeeds, then a new, simpler and more compact version of the exclusion argument is available. While I argue against the consequent of this conditional, thereby also rejecting the antecedent, this dialectical feature should be of interest to philosophers on either side of this debate.

As conceived by Kim, the causal exclusion argument targets all forms of nonreductive physicalism equally, but by restricting its focus to functionalist varieties of nonreductivism, I am able to develop a version of the argument that has a number of virtues lacking in the original. First, the revised argument has no need for Kim’s causal exclusion principle, which many find dubious if not simply false. Second, the revised argument can be adapted to either a production-based conception of causation, as Kim (...) himself favors, or to any of a number of dependence-based conceptions, like the ones favored by many of Kim’s critics. And, finally, the revised argument does not have the objectionable consequence that all so-called higher-level properties are epiphenomenal, for it does not generalize in the way that Kim’s original version of the argument arguably does. Nor does it concede much to narrow the scope of the argument in the way proposed. Those who adopt nonreductive theories of mind do so, by and large, on the strength of functionalist arguments for the multiple realizability of mental states. If functionalism entails that mental properties are epiphenomenal, this thus deals a critical, if not quite fatal, blow to nonreductivism. (shrink)

The aim of this paper is to demonstrate that the postulation of irreducible, distributed cognitive systems is necessary for the successful explanatory practice of cognitive science and sociology. Towards this end, and with an eye specifically on the phenomenon of distributed cognition, the debate over reductionism versus emergence is examined from the perspective of Dynamical Systems Theory. The motivation for this novel approach is threefold. Firstly, DST is particularly popular amongst cognitive scientists who work on modelling collective behaviors. Secondly, DST (...) can deliver two distinct arguments in support of the claim that the presence of mutual interactions between group members necessitates the postulation of the corresponding group entity. Thirdly, DST can also provide a succinct understanding of the way group entities exert downward causation on their individual members. The outcome is a naturalist account of the emergent, and thereby irreducible, nature of distributed cognitive systems that avoids the reductionists’ threat of epiphenomenalism, while being well in line with materialism.

For some time now, Jaegwon Kim has argued that irreducible mental properties face the threat of causal inefficacy. The primary weapon he deploys to sustain this charge is the supervenience/exclusion argument. This argument, in a nutshell, states that any mental property that irreducibly supervenes on a physical property is excluded from causal efficacy because the underlying physical property takes care of all of the causal work itself. Originally intended for mental properties alone, it did not take long for his critics (...) to suggest the argument generalizes across all of the special science properties as well. Kim responds in two different ways to the generalization problem. The first response, which I call the higher-level solution, is ably dismissed by numerous critics. The second response, which I call the identity solution, has not faced comparable scrutiny. In this paper I argue that the identity solution faces numerous problems of its own. (shrink)

In recent years, emergentism has resurfaced as a possible method by which to secure autonomous mental causation from within a physicalistic framework. Critics argue, however, that emergentism fails, since emergentism entails that effects have sufficient physical causes, so they cannot also have distinct mental causes. In this paper I argue that this objection may be effective against supervenient emergentism, but it is not established that it is effective against mereological emergentism. In fact, after demonstrating that two founding emergentists, Samuel Alexander (...) and C. Lloyd Morgan, are mereological emergentists, I show how mereological emergentism provides fresh responses to the causal exclusion problem. (shrink)

The type-type reductive identity of the mental to the physical was once the dominant position in the mental causation debate. In time this consensus was overturned, largely due to its inability to handle the problem of multiple realizability. In its place a nonreductive position emerged which often included an adherence to functionalism. Functionalism construes mental properties as functional states of an organism, which in turn have specific physical realizers. This nonreductive form of functionalism, henceforth called role functionalism, has faced a (...) number of criticisms itself. Chief among these is the concern that the realizer of the functional role is causally sufficient, so the role property does not make a contribution of its own. In this paper I argue that there is a way for unreduced functional properties to play a role after all. This is done by conceiving of functional properties as higher level functional properties of a macro system which determine that its realizers will play the roles that they play. (shrink)

Nonreductive physicalists endorse the principle of mental causation, according to which some events have mental causes: Sid climbs the hill because he wants to. Nonreductive physicalists also endorse the principle of physical causal completeness, according to which physical events have sufficient physical causes: Sid climbs the hill because a complex neural process in his brain triggered his climbing. Critics typically level the causal exclusion problem against this nonreductive physicalist model, according to which the physical cause is a sufficient cause of (...) the behavioural effect, so the mental cause is excluded from causally influencing Sid’s behaviour. In this paper I demonstrate how numerous nonreductive physicalists have responded to the causal exclusion problem by weakening the principle of physical causal completeness in numerous ways. The result: either numerous nonreductive physicalist solutions fail on account of the fact that they do not satisfy a robustly defined principle of physical causal completeness, or there is an accelerating trend of solving the causal exclusion problem by suitably weakening the principle of physical causal completeness.

Kim attribue aux émergentistes un modèle de « réduction logique » dans lequel la prédiction ou l’explication d’une occurrence de la propriété réduite ne requiert, outre des informations sur le niveau réducteur, que des principes logiques et mathématiques. Sur la base de cette interprétation, je conteste deux thèses de Kim. La première concerne la légitimité du modèle émergentiste de réduction. J’essaie de montrer, à l’aide de l’exemple de l’addition des masses, que l’adoption de la réduction logique rendrait irréductibles certaines propriétés (...) qui sont clairement réductibles. La deuxième est la thèse selon laquelle la réduction fonctionnelle correspond aux exigences émergentistes sur la réduction. Telle que Kim la caractérise, la réduction fonctionnelle comporte, outre une définition fonctionnelle de la propriété à réduire, l’indication des propriétés réalisatrices. Or cette information, qui correspond à la découverte d’une loi de correspondance , est empirique et non seulement logique.I read Kim as attributing to the emergentists a model of “logical reduction” in which the prediction or explanation of an occurrence of the reduced property requires, beyond information on the reducing level, only logical and mathematical principles. On the basis of this interpretation, I argue against two theses of Kim's. The first concerns the legitimacy of the emergentist model of reduction. I try to show by the example of the addition of masses that according to logical reduction certain properties which are clearly reducible come out as irreducible. The second is the thesis that functional reduction as construed by Kim satisfies the emergentist constraints on reduction. Functional reduction implies, over and above a functional definition of the reduced property, the indication of its realizers. But this information corresponding to the discovery of a bridge law is empirical and not only logical. (shrink)

We argue that embedded cognition provides an argument against Jaegwon Kim’s neural reduction of mental causation. Because some mental, or at least psychological processes have to be cast in an externalist way, Kim’s argument can be said to lead to the conclusion that mental causation is as safe as any other form of higher-level of causation.

This paper tries to show that Kim's strategy of preventing the problem of generalization of mental causation is not successful and that his original supervenience argument can be applied to cases of nonmental macrolevel causation, with the effect that nonmental macroproperties which only supervene on, but are not identical with, configurations of microproperties turn out to be epiphenomenal after all.

In recent years Jaegwon Kim has offered an argument – the ‘supervenience argument’ – to show that supervenient mental properties, construed as second- order properties distinct from their first-order realizers, do not have causal powers of their own. In response, several philosophers have argued that if Kim’s argument is sound, it generalizes in such a way as to condemn to causal impotency all properties above the level of basic physics. This paper discusses Kim’s supervenience argument in the context of his (...) reply to this so-called ‘generalization argument’. In particular, the paper focuses on the level/order distinction, to which Kim appeals in his reply to the generalization argument, and on the relation between this distinction and two varieties of functionalism, ‘realizer’ vs. ‘role’ functionalism. The author argues that a proper analysis of the notions of levels and orders undermines Kim’s response to the generalization argument, and suggests that Kim’s reductionist strategy for vindicating the causal powers of mental properties is better served if mental properties are construed as first-order properties, as realizer-functionalism recommends.

By quantifying over properties we cannot create new properties any more than by quantifying over individuals we can create new individuals. Someone murdered Jones, and the murderer is either Smith or Jones or Wang. That “someone,” who murdered Jones, is not a person in addition to Smith, Jones, and Wang, and it would be absurd to posit a disjunctive person, Smith‐or‐Jones‐or‐Wang, with whom to identify the murderer. The same goes for second‐order properties and their realizers. (Kim 1997a, 201).

You may speak of a chain, or if you please, a net. An analogy is of little aid. Each cause brings about future events. Without each the future would not be the same. Each is proximate in the sense it is essential. But that is not what we mean by the word. Nor on the other hand do we mean sole cause. There is no such thing.

Nonreductive physicalism is currently one of the most widely held views about the world in general and about the status of the mental in particular. However, the view has recently faced a series of powerful criticisms from, among others, Jaegwon Kim. In several papers, Kim has argued that the nonreductivist's view of the mental is an unstable position, one harboring contradictions that push it either to reductivism or to eliminativism. The problems arise, Kim maintains, when we consider the causal powers (...) that mental properties are held to carry on the nonreductivist's view and the causal transactions into which mental events are said to enter. My aim here is less than that of defending nonreductive physicalism against all of Kim's criticisms. I wish primarily to call into question the claim that nonreductive physicalism is committed to emergentism with respect to the causal powers of the mental. As subsidiary points, I shall offer a limited defense of nonreductivism against two related objections that Kim raises. However, even if my conclusions are correct, problems remain for the nonreductivist's treatment of mental causation. I shall close the paper with a brief discussion of these difficulties. (shrink)

RÉSUMÉ Dans la foulée de divers arguments antiphysicalistes visant à montrer que les qualia ne sont pas fonctionnalisables, Ned Block a proposé un autre argument de ce type, qui repose sur son expérience de pensée de la Terre inversée. L’argument de Block montrerait qu’un sujet peut avoir deux expériences de couleur du même type « phénoménal » qui seraient de deux types fonctionnels distincts puisque, selon lui, elles auraient des contenus intentionnels distincts. Il existerait donc une différence fondamentale entre le (...) contenu phénoménal des expériences sensorielles et leur contenu intentionnel et, dans la mesure où le contenu phénoménal ne pourrait être fonctionnalisé, le fonctionnalisme serait ainsi réfuté, à tout le moins en ce qui concerne les expériences sensorielles. Je soulève une objection qui, si elle est correcte, montre que la distinction que Block tente d’établir entre le contenu phénoménal et le contenu intentionnel des expériences est incohérente. ABSTRACT Following the popular trend of antiphysicalist arguments which aim at showing that qualia cannot be functionalized, Ned Block has suggested yet another antiphysicalist argument, on the basis of his Inverted Earth thought experiment. The purpose of his argument is to show that a subject could have two color experiences which are of the same phenomenal type but of different functional types, insofar as they have different intentional contents. This argument would support the idea that there exists a substantial distinction between the phenomenal content of sensory experiences and their intentional content, and that functionalism is false, at least with respect to sensory experiences. I raise an objection to Block's argument which, if correct, shows that the distinction he proposes between the phenomenal and the intentional content of sensory experiences is incoherent. (shrink)

In recent years, a hierarchical view of reality has become extremely influential. In order to understand the world as a whole, on this view, we need to understand the nature of the fundamental constituents of the world. We also need to understand the relations that build the world up from these fundamental constituents. Building pluralism is the view that there are at least two equally fundamental relations that together build the world. It has been widely, though tacitly, assumed in a (...) variety of important metaphysical debates. However, my primary aim in this paper is to argue that this has been a mistake. I will show that serious problems concerning the relationship between building and fundamentality afflict pluralism and are likely fatal to it. I claim that, for better or worse, our best hope is building singularism, the view that there is a single most fundamental building relation. I conclude by examining the advantage that singularist accounts enjoy over their pluralist rivals. (shrink)

A variety of relations widely invoked by philosophers—composition, constitution, realization, micro-basing, emergence, and many others—are species of what I call ‘building relations’. I argue that they are conceptually intertwined, articulate what it takes for a relation to count as a building relation, and argue that—contra appearances—it is an open possibility that these relations are all determinates of a common determinable, or even that there is really only one building relation.

ABSTRACT: A popular strategylor resolving Kim 's exclusion problem is to suggest that mental and physical property tropes are identical despite the non-identity of the mental and physical properties themselves. I argue that mental and physical tropes can be identified without losing the dispositional character of mentality only if a dual-character hypothesis regarding the intrinsic characters of tropes is endorsed. But even with this assumption, the causaI efficacy of the wrong dispositions is secured.RÉSUMÉ: On résout habituellement le problème de l'exclusion (...) de Kim en suggérant que les tropes de propriété mentale et physique sont identiques en dépit de la non-identité des propriétés mentales et physiques elles-mêmes. Je soutiens que les tropes mentaux et physiques peuvent être ramenés l'un à l'autre sans perdre le caractère dispositionnel de la pensée, à la condition d'approuver une hypothèse sur la nature double des caractères intrinsèques des tropes. Même en suivant cette proposition, l'efficacité causale des dispositions fausses est maintenue. (shrink)

The functionalist conception of mental properties, together with their multiple realizability, is often taken to entail their irreducibility. It might seem that the only way to revise that judgement is to weaken the requirements traditionally imposed on reduction. However, Jaegwon Kim has recently argued that we should, on the contrary, strengthen those requirements, and construe reduction as what I propose to call “logical reduction”, a model of reduction inspired by emergentism. Moreover, Kim claims that what he calls “functional reduction” allows (...) one to reduce (at least some) mental properties by these new standards. I argue against both theses. First, I present a counterexample to the emergentist model of reduction: The model judges irreducible certain properties which are clearly reducible. Second, I contestthat functional reduction as construed by Kim satisfies the emergentist constraints. Functional reduction implies, over and above a functional definition of the reduced property, the indication of its realizers. But the latter information corresponding to the discovery of a (local) bridge law, is empirical and not purely logical. (shrink)

There is a tension or even contradiction between mental causation - the belief that some mental events or properties are causally relevant for some physical events or properties - and the irreducibility of mental features to physical ones, the causal closure of the physical, and the assumption that there is no overdetermination of the physical. To reconcile these premises was a promise of nonreductive physicalism, but a closer inspection shows that it is, on the contrary, a source of the problem (...) - namely, the unintelligibility of mental causation. This has to do with the widely-held assumption that the mental supervenes on the physical. How can the mental be causally relevant, then? And what is the relationship of the mental and the physical? There are many options, including identity, realizationism, emergence, or some kind of reducibility. But they all have their own problems, e.g. they threaten mental reality, the causal closure of the physical, or scientific explanations. All these aspects are covered in Jaegwon Kim's book Mind in a Physical World. This paper is a detailed introduction to it, discussing and critically commenting it and those still intriguing, but also confusing and complicated issues of the mind-body problem, especially the ontology of mental causation.

Throughout the 1990s, Jaegwon Kim developed a line of argument that what purport to be nonreductive forms of physicalism are ultimately untenable, since they cannot accommodate the causal efficacy of mental states. His argument has received a great deal of discussion, much of it critical. We believe that, while the argument needs some tweaking, its basic thrust is sound. In what follows, we will lay out our preferred version of the argument and highlight its essential dependence on a causal-powers metaphysic, (...) a dependence that Kim does not acknowledge in his official presentations of the argument.i We then discuss two recent physicalist strategies for preserving the causal efficacy of the mental in the face of this sort of challenge, strategies that (ostensibly) endorse a causal powers metaphysics of properties while offering distinctive accounts of the physical realization of mental properties. We argue that neither picture can be satisfactorily worked out, and that seeing why they fail strongly suggests that nonreductive physicalism and a causal powers metaphysic are not compatible, as our original argument contends. Since we also believe that robust realism concerning mental causation should not be abandoned, we take the argument of this paper to strongly motivate an account on which the mental is unrealized by and ontologically emergent from the physical. In a final section, we sketch what an ontologically emergentist account of the mental might look like. (shrink)

Color relationalism is the view that colors are constituted in terms of relations between subjects and objects. The most historically important form of color relationalism is the classic dispositionalist view according to which, for example red is the disposition to look red to standard observers in standard conditions (mutatis mutandis for other colors).1 However, it has become increasingly apparent in recent years that a commitment to the relationality of colors bears interest that goes beyond dispositionalism (Cohen, 2004; Matthen, 1999, 2001, (...) 2005; Thompson, 1995). Accordingly, it is an important project for those interested in the metaphysics of color to sort through and assess different forms of color relationalism. There is, however, a powerful and general cluster of objections that has been thought by many to amount to a decisive refutation of any and all forms of color relationalism. Although this idea has been developed in a number of ways, the basic thought is that relationalism — qua theory of color — is at odds with the manifest evidence of color phenomenology, and that this clash between theory and data should be resolved by giving up the theory.

I examine the debate between reductive and non-reductive physicalists, and conclude that if we are to be physicalists, then we should be reductive physicalists. I assess how both reductionists and non-reductionists try to solve the mind-body problem and the problem of mental causation. I focus on the problem of mental causation as it is supposed to be faced by non-reductionism: the so-called overdetermination problem. I argue that the traditional articulation of that problem is significantly flawed, and I show how to (...) articulate it properly: what I call the ‘super-overdetermination problem’. In doing so, I demonstrate that the problem of mental causation faced by non-reductionism is in fact a special case of the mind-body problem, as faced by non-reductionism, and that the former can’t be solved independently of the latter. I then assess the prospects for a particular family of non-reductive views that I call immanentism, and show that they fail to solve the super-overdetermination problem. Finally, I put forward two arguments to support the conclusion that physicalism entails reductionism. Both arguments establish, via distinct reasoning, the proposition that mental property instances are identical to physical property instances; and then each argument employs the inference, which I also defend, that if mental instances are physical instances, then mental properties are physical properties; hence, reductionism follows.

We defend Jaegwon Kim’s ‘causal inheritance’ principle from an objection raised by Jurgen Schröder. The objection is that the principle is inconsistent with a view about mental properties assumed by Kim, namely, that they are second-order properties. We argue that Schröder misconstrues the notion of second-order property. We distinguish three notions of second-order property and highlight their problems and virtues. Finally, we examine the consequence of Kim’s principle and discuss the issue of whether Kim’s ‘supervenience argument’ generalizes to all special (...) sciences or not. (shrink)
