The Exclusion Problem (ep) for mental causation suggests that there is a tension between the claim that the mental causes physical effects and the claim that the mental does not overdetermine its physical effects. In response, Karen Bennett (2003, 2008) puts forward an extra necessary condition for overdetermination: if one candidate cause were to occur but the other were not to occur, the effect would still occur. She thus denies one of the assumptions of ep, the assumption that if an (...) effect has two sufficient causes, it is overdetermined. If sound, her argument does two things: it solves ep, and it shows how to use counterfactuals in order to make the notion of overdetermination precise. However, the argument is not sound. (shrink)

The basic form of the exclusion problem is by now very, very familiar. 2 Start with the claim that the physical realm is causally complete: every physical thing that happens has a sufficient physical cause. Add in the claim that the mental and the physical are distinct. Toss in some claims about overdetermination, give it a stir, and voilá—suddenly it looks as though the mental never causes anything, at least nothing physical. As it is often put, the physical does all (...) the work, and there is nothing left for the mental to do. (shrink)

This paper addresses two objections raised against anomalous monism. Firstly, on the basis of Davidson's assertion that all causal relations fall under strict laws, many critics conclude mental properties are causally inert since they are non-nomic. I argue that this conclusion follows only on the further assumption that all causally efficacious properties are nomic properties. It is perfectly consistent, however, to hold that there is a law covering each causal relation without each causal statement being the instantiation of a law. (...) Secondly, I countervail Kim's claim that the only option open to physicalists is reductionism by showing how weak supervenience preserves both the dependence of the mental on the physical and the irreducibility of mental explanations to physical ones. (shrink)

The anti-reductionist who wants to preserve the causal efficacy of mental phenomena faces several problems in regard to mental causation, i.e. mental events which cause other events, arising from her desire to accept the ontological primacy of the physical and at the same time save the special character of the mental. Psychology tries to persuade us of the former, appealing thereby to the results of experiments carried out in neurology; the latter is, however, deeply rooted in our everyday actions and (...) beliefs and despite the constant opposition of science still very much alive. Difficulties, however, arise from a combination of two claims that are widely accepted in philosophy of mind, namely, physical monism and mental realism, the acceptance of which leads us to the greatest problem of mental causation: the problem of causal exclusion. Since physical causes alone are always sufficient for physical effects mental properties are excluded from causal explanations of our behaviour, which makes them “epiphenomenal”. The article introduces Van Gulick’s solution to the exclusion problem which tries to prove that physical properties, in contrast to mental properties, do not have as much of a privileged status with respect to event causation as usually ascribed. Therefore, it makes no sense to say that physical properties are causally relevant whereas mental properties are not. This is followed by my objection to his argument for levelling mental and physical properties with respect to causation of events. I try to show that Van Gulick’s argument rests on a premise that no serious physicalist can accept. (shrink)

I take it that the following is a desideratum of our theories in the philosophy of mind. A theory in the philosophy of mind should help us better understand ourselves as agents and aid in our theorizing about the nature of action and agency. In this paper I discuss a strategy adopted by some defenders of nonreductive physicalism in response to the problem of causal exclusion. The strategy, which I refer to as “intralevelism,” relies on treating mental causation as intra (...) level mental to mental causation, rather than as involving any inter level mental to physical causation. I raise problems for intralevelist theories of mental causation that stem from action-theoretic considerations. Specifically, I focus on the failure of intralevelist proposals to account for the problem of basic causal deviance in the etiology of action. To the extent that intralevelism fails to make room for basic causal deviance, the strategy fails to satisfy the aforementioned desideratum, viz ., that our theories in the philosophy of mind should be of use in theorizing about action and agency. The upshot is that intralevelism is a less promising strategy for nonreductive physicalists than it appears at first glance. (shrink)

This paper identifies and critiques a theory of mental causation defended by some proponents of nonredutive physicalism that I call “intralevelism.” Intralevelist theories differ in their details. On all versions, the causal outcome of the manifestation of physical properties is physical and the causal outcome of the manifestation of mental properties is mental. Thus, mental causation on this view is intralevel mental to mental causation. This characterization of mental causation as intralevel is taken to insulate nonreductive physicalism from some objections (...) to nonreductive physicalism, including versions of the exclusion argument. This paper examines some features of three recent versions of intralevelism defended by John Gibbons, Markus Schlosser, and Amie Thomasson. This paper shows that the distinctive problems faced by these three representative versions of intralevelism suggest that the intralevelist strategy does not provide a viable solution to the exclusion problem. (shrink)

The exclusion problem is held to show that mental and physical events are identical by claiming that the denial of this identity is incompatible with the causal completeness of physics and the occurrence of mental causation. The problem relies for its motivation on the claim that overdetermination of physical effects by mental and physical causes is objectionable for a variety of reasons. In this paper, I consider four different definitions of ?overdetermination? and argue that, on each, overdetermination in all cases (...) of mental causation either does not occur or is unobjectionable, even when mental and physical events are non-identical. I therefore conclude that the exclusion problem cannot be used as a reason to accept that mental and physical events are identical unless some other definition of ?overdetermination? is provided. (shrink)

Given Kim’s principle of explanatory exclusion (EE), it follows that in addition to the problem of mental causation, dualism faces a problem of mental explanation. However, the plausibility of EE rests upon the acceptance of a further principle concerning the individuation of explanation (EI). The two methods of defending EI—either by combining an internal account of the individuation of explanation with a semantical account of properties or by accepting an external account of the individuation of explanation—are both metaphysically implausible. This (...) is not, however, to reject the problem of mental explanation, for EE can be replaced with a far weaker principle, which does not require the acceptance of EI, but which generates a similar problem for dualism. (shrink)

In this paper I develop a novel response to the exclusion problem. I argue that the nature of the events in the causally complete physical domain raises the “problem of many causes”: there will typically be countless simultaneous low-level physical events in that domain that are causally sufficient for any given high-level physical event (like a window breaking or an arm raising). This shows that even reductive physicalists must admit that the version of the exclusion principle used to pose the (...) exclusion problem against non-reductive physicalism is too strong. The burden is on proponents of the exclusion problem to provide a reason to think that any qualifications placed on the exclusion principle will solve the problem of many causes while ruling out causation by irreducible mental events. (shrink)

I argue that the completeness of physics is composed of two distinct claims. The first is the commonly made claim that, roughly, every physical event is completely causally determined by physical events. The second has rarely, if ever, been explicitly stated in the literature and is the claim that microphysics provides a complete inventory of the fundamental categories that constitute both the causal features and intrinsic nature of all the events that causally affect the physical universe. After showing that these (...) claims are distinct, I argue that they can be used to solve a difficulty with existing responses to the exclusion problem—namely, that these existing responses also undermine the powerful causal argument for physicalism. Recognizing that there are two kinds of completeness opens up room for the nonreductive physicalist to solve the exclusion problem while also endorsing a modified, cogent causal argument for a kind of physicalism compatible with her position.

Terry Horgan University of Memphis In this paper I address the problem of causal exclusion, specifically as it arises for mental properties (although the scope of the discussion is more general, being applicable to other kinds of putatively causal properties that are not identical to narrowly physical causal properties, i.e., causal properties posited by physics). I summarize my own current position on the matter, and I offer a defense of this position. I draw upon and synthesize relevant discussions in various (...) <blockquote> [1] </blockquote> other papers of mine (some collaborative) that bear on this topic. (shrink)

The hypothesis of the mental state-causation of behavior (the MSC hypothesis) asserts that the behaviors we classify as actions are caused by certain mental states. A principal reason often given for trying to secure the truth of the MSC hypothesis is that doing so is allegedly required to vindicate our belief in our own agency. I argue that the project of vindicating agency needs to be seriously reconceived, as does the relation between this project and the MSC hypothesis. Vindication requires (...) addressing what I call the agent-exclusion problem: the prima facie incompatibility between the intentional content of agentive experience and certain metaphysical hypotheses often espoused in philosophy.

Jaegwon Kim’s causal exclusion argument says that if all physical effects have sufficient physical causes, and no physical effects are caused twice over by distinct physical and mental causes, there cannot be any irreducible mental causes. In addition, Kim has argued that the nonreductive physicalist must give up completeness, and embrace the possibility of downward causation. This paper argues first that this extra argument relies on a principle of property individuation, which the nonreductive physicalist need not accept, and second that (...) once we get clear on overdetermination, there is a way to reject the exclusion principle upon which the causal exclusion argument depends, but third that this should not lead to the belief that mental causation is easily accounted for in terms of counterfactual dependencies. (shrink)

The paper argues that mental causation can be explained from the sufficiency of counterfactual dependence for causation together with relatively weak assumptions about the metaphysics of mind. If a physical event counterfactually depends on an earlier physical event, it also counterfactually depends on, and hence is caused by, a mental event that correlates with (or supervenes on) this earlier physical event, provided that this correlation (or supervenience) is sufficiently modally robust. This account of mental causation is consistent with the overdetermination (...) of physical events by mental events and other physical events, but does not entail it. (shrink)

It is often argued that higher-level special-science properties cannot be causally efficacious since the lower-level physical properties on which they supervene are doing all the causal work. This claim is usually derived from an exclusion principle stating that if a higher-level property F supervenes on a physical property F* that is causally sufficient for a property G, then F cannot cause G. We employ an account of causation as difference-making to show that the truth or falsity of this principle is (...) a contingent matter and derive necessary and sufficient conditions under which a version of it holds. We argue that one important instance of the principle, far from undermining non-reductive physicalism, actually supports the causal autonomy of certain higher-level properties. (shrink)

In numerous papers Jaegwon Kim argues that nonreductive materialists (i.e., those philosophers who believe that there are no irreducible non-physical objects in the universe, and yet there are irreducible psychological properties which are indispensable in intentional psychological explanations) face two problems. One is that intentional mental properties are not causally relevant; the other is that explanations appealing to these properties are excluded by explanations appealing to physical, in particular, microphysical, properties.1 The first problem can be called the problem of epiphenomenalism. (...) The second problem is what Kim calls the problem of explanatory/causal exclusion. Epiphenomenalism is not just a problem for nonreductive materialists, but a problem for psychology (as a science of psychological explanation), and for anyone who believes that our thought is the cause of our action. Kim argues that the exclusion problem, on the other hand, is especially a problem for nonreductive materialists. Nonreductive materialists typically buy into the principle of the causal closure of the physical domain, according to which "any physical event that has a cause at time t has a physical cause at t..... [I]f we trace the causal ancestry of a physical event, we need never go outside the physical domain." [Kim 1989b, p. 280] One cannot reject this principle unless one is willing to go back to Cartesian dualism. But the problem is, if all causation is done at the physical level, then there is no causal work left for mental kinds. If mental kinds do not play any causal role, then intentional psychological explanations that appeal to mental properties are not warranted. Therefore, Kim concludes, nonreductive materialism is an untenable position. Some nonreductionists (Davidson, Dretske, LePore & Loewer, Jackson & Pettit, for example) have tried to argue for the causal relevancy of mental properties from an.. (shrink)

Jaegwon Kim has argued that unless mental events are reducible to subvening physical events, they are at best overdeterminers of their effects. Recently, nonreductive physicalists have endorsed this consequence claiming that the relationship between mental events and their physical bases is tight enough to render any such overdetermination nonredundant, and hence benign. I focus on instances of this strategy that appeal to the notion of constitution. Ultimately, I argue that there is no way to understand the relationship between irreducible mental (...) events and their physical bases such as to both eliminate causal redundancy and preserve the efficacy of mental events. (shrink)

In this paper, I argue that Locke is not in fact agnostic about the ultimate nature of the mind. In particular, he produces an argument, much like Jaegwon Kim's exclusion argument, to show that any materialist view that takes mental states to supervene on physical states is committed to epiphenomenalism. This result helps illuminate Locke's otherwise puzzling notion of 'superaddition.'.

In this paper I argue that causation is an essentially macroscopic phenomenon, and that mental causes are therefore capable of outcompeting their more specific physical realizers as causes of physical effects. But I also argue that any causes must be type-identical with physical properties, on pain of positing inexplicable physical conspiracies. I therefore allow macroscopic mental causation, but only when it is physically reducible.

In this brief note I claim that, contrary to what Esfeld argues in his paper in this same volume, Kim's position with respect to the problem of causal exclusion does indeed commit him to the causal heterogeneity of realized properties.

In a series of influential articles (Kim 1989b, 1992b, 1993a and 1998), Jaegwon Kim has developed a strong argument against nonreductive physicalism as a plausible solution to mental causation. The argument is commonly called the ’causal exclusion argument’, and it has become, over the years, one of the most serious threats to the nonreductivist point of view. In the first part of this paper I offer a careful reconstruction and detailed discussion of the exclusion argument. In the second part I (...) show why some important objections to it actually fail.

The issue of downward causation (and mental causation in particular), and the exclusion problem is discussed by taking into account some recent advances in the philosophy of science. The problem is viewed from the perspective of the new interventionist theory of causation developed by Woodward. It is argued that from this viewpoint, a higher-level (e.g., mental) state can sometimes truly be causally relevant, and moreover, that the underlying physical state which realizes it may fail to be such.

The importance of the exclusion argument for contemporary physicalism is emphasized. The recent attempts to vindicate reductive physicalism by invoking certain needed revisions to the Nagelian model of reduction are then discussed. It is argued that such revised views of reduction offer in fact much less help to reductive physicalism than is sometimes supposed, and that many of these views lead to trouble when combined with the exclusion argument.

An analysis and rebuttal of Jaegwon Kim's reasons for taking nonreductive physicalism to entail the causal irrelevance of mental features to physical phenomena, particularly the behaviour of human bodies.

This paper focuses on two prominent arguments claiming that physicalism entails reductionism. One is Kim’s causal exclusion argument (CEA), and the other is Papineau’s causal argument. The paper argues that Kim’s CEA is not logically valid. Rather, Kim’s [2005: p. 36] argument is driven by ‘Edward’s dictum’, which is alien to non-reductive physicalism and should be rejected. Further, Papineau’s causal argument only arrives at the physical property-property identities by using a conception of the physical that licenses anything to be reductively (...) physical, including putative core anti-physical entities. Thus, Papineau’s causal argument does not have a reductive physicalist conclusion of philosophical interest. (shrink)

This is about a proposed solution to the exclusion problem, one I've defended elsewhere (for example, in "The Properties of Mental Causation"). Details aside, it's just the identity theory: mental properties face no threat of exclusion from, or preemption by, physical properties, because every mental property is a physical property. Here I elaborate on this solution and defend it from some objections. One of my goals is to place it in the context of a more general ontology of properties, in (...) particular, a trope ontology. (shrink)

Recent discussions of mental causation have focused on three principles: (1) Mental properties are (sometimes) causally relevant to physical effects; (2) mental properties are not physical properties; (3) every physical event has in its causal history only physical events and physical properties. Since these principles seem to be inconsistent, solutions have focused on rejecting one or more of them. But I argue that, in spite of appearances, (1)–(3) are not inconsistent. The reason is that 'properties' is used in different senses (...) in the principles. In (1) and (3), 'properties' should be read as 'tropes' (properties here are particulars), while in (2) 'properties' should read as 'types' (properties here are universals or classes). Although mental types are distinct from physical types, every mental trope is a physical trope. This allows mental properties to be causally relevant to physical effects without violating the closed character of the physical world. (shrink)

Worries about mental causation are prominent in contemporary discussions of the mind and human agency. Originally, the problem of mental causation was that of understanding how a mental substance (thought to be immaterial) could interact with a material substance, a body. Most philosophers nowadays repudiate immaterial minds, but the problem of mental causation has not gone away. Instead, focus has shifted to mental properties. How could mental properties be causally relevant to bodily behavior? How could something mental qua mental cause (...) what it does? After looking at the traditional Problem of Interaction, we survey various versions of the property-based problem and look at proposed solutions to them. (shrink)

Sydney Shoemaker’s ‘Subset Account’ offers a new take on determinable properties and the realization relation as well as a defense of non-reductive physicalism from the problem of mental causation. At the heart of this account are the claims that (1) mental properties are determinable properties and (2) the causal powers that individuate a determinable property are a proper subset of the causal powers that individuate the determinates of that property. The second claim, however, has led to the accusation that the (...) effects caused by the instantiation of a determinable property will also be caused by the instantiation of the determinates of that property—so instead of solving the problem of mental causation, the Subset Account ends up guaranteeing that the effects of mental properties (and all other types of determinable property) will be causally overdetermined! In this paper, I explore this objection. I argue that both sides in this debate have failed to engage the question at the heart of the objection: Given that both a determinable property and its determinates have the power to cause some effect (E), does it follow that both will actually cause E when the relevant conditions obtain? To make genuine progress towards answering this question, we need to take a serious look at the metaphysics of causation. With the debate properly reframed and issues about the metaphysics of causation front and center, I explore the question of whether the Subset Account is doomed to result in problematic causal overdetermination.

Abstract: The paper begins with the assumption that psychological event tokens are identical to or constituted from physical events. It then articulates a familiar apparent problem concerning the causal role of psychological properties. If they do not reduce to physical properties, then either they must be epiphenomenal or any effects they cause must also be caused by physical properties, and hence be overdetermined. It then argues that both epiphenomenalism and over-determinationism are prima facie perfectly reasonable and relatively unproblematic views. The (...) paper proceeds to argue against Kim's ( Kim, 2000, 2005 ) attempt to articulate a plausible version of reductionism. It is then argued that psychological properties, along with paradigmatically causally efficacious macro-properties, such as toughness, are causally inefficacious in respect of their possessor's typical effects, because they are insufficiently distinct from those effects. It is finally suggested that the distinction between epiphenomenalism and overdeterminationism may be more terminological than real. (shrink)

The by now famous exclusion problem for mental causation admits only one possible solution, as far as I can see, namely: that mental and physical properties are linked by a vertical relation. In this paper, starting from what I take to be sensible premises about properties, I will be visiting some general relations between them, in order to see whether, first, it is true that some vertical relation, other than identity, makes different sorts of causation compatible and second, whether physical (...) and mental properties can be pairs of such relation. (shrink)

I argue that an independently attractive account of causation and causal explanation provides a principled resolution of the exclusion problem.

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.

Non-reductive physicalism is committed to two theses: first, that mental properties are ontologically autonomous, and second, that physicalism is true. Jaegwon Kim has argued that this view is unstable – to honor one thesis, one must abandon the other. In this paper, I present an account of property realization that addresses Kim’s criticism and that explains how the two theses are indeed comfortably compatible.

A quite popular approach to solving the Causal Exclusion Problem is to adopt a counterfactual theory of causation. In this paper, I distinguish three versions of the Causal Exclusion Argument. I argue that the counterfactualist approach can block the first two exclusion arguments, because the Causal Inheritance Principle and the Upward Causation Principle upon which the two arguments are based respectively are problematic from the perspective of the counterfactual account of causation. However, I attempt to show that the counterfactualist approach (...) is unable to refute a sophisticated version (i.e. the third version) of the exclusion argument in that the Downward Causation Principle, a premise of the third exclusion argument, is actually implied by the counterfactual theory of causation. Therefore, even if other theories of causation might help the non-reductive physicalist to solve the exclusion problem, the counterfactual theory of causation cannot. (shrink)
