It is quite obvious why the antireductionist picture of mental causation that rests on supervenience is an attractive theory. On the one hand, it secures uniqueness of the mental; on the other hand, it tries to place the mental in our world in a way that is compatible with the physicalist view. However, Kim reminds us that anti-reductionists face the following dilemma: either mental properties have causal powers or they do not. If they have them, we risk a violation of the causal closure of the physical domain; if they do not have them, we embrace epiphenomenalism, which denies any sort of causal powers to the mental. So, either we violate the causal closure of physics, or we end up with epiphenomenalism. The first two sections of the article describe the problem of causal exclusion and Kim’s causal dilemma. The last two introduce Horgan’s antireductionist answer and my objection to that answer.

causation-——the causation of what we do by what we think—be comes a problem against a particular metaphysical background. My aim is twofold: first, to root out the metaphysical assumptions that generate the problem of mental causation and to show that they preclude its solution; second, to dissolve the problem of mental causation by motivating rejection of one of the metaphysical assumptions that give rise to it. There are three features of this metaphysical background picture that are important for our purposes. The first concerns the nature of reality: all reality depends on physical reality, where physical reality consists of a network of events.1 The second concerns the nature of..

Mental causation, though a forceful intuition embedded in our commonsense psychology, is difficult to square with the rest of commitments of physicalism about the mind. Advocates of mental causation have found solace in the causal inheritance principle, according to which the mental properties of mental states share the causal powers of their physical counterparts. In this paper, I present a variety of counterarguments to causal inheritance and conclude that the requirements for causal inheritance are stricter than what standing versions of said principle imply. In line with this, physicalism may be destined to epiphenomenalism unless multiple realizability turns out false.

Stephen Yablo has recently argued for a novel solution to the mental causation problem: the mental is related to the physical as determinables are related to determinates; determinables are not causal rivals with their determinates; so the mental and the physical are not causal rivals. Despite its attractions the suggestion seems hard to accept. In this paper I develop the idea that mental properties and physical properties are not causal rivals. Start with property dualism, supervenience, multiple realizability, and the claim that no more than one supervenience base for a mental property can be had by a single instance of the mental property. Then a probabilistic account of causation will be unable to certify either mental properties or physical properties as causal factors for effect types. I suggest that this shows that we should not count mental properties as causal rivals with physical properties.

Consider the following dilemma for non-reductive physicalism. If mental events cause physical events, they merely overdetermine their effects, given the causal closure of the physical. And if mental events cause only other mental events, they do not make the kind of difference we want them to. This dilemma can be avoided once the dichotomy between physical and mental events is dropped. Mental events make a real difference if they cause actions. But actions, I will argue, are neither mental nor physical events. Actions are realized by physical events, but they are not type-identical with them. This gives us non-reductive physicalism without downward causation. The tenability of such a view has been questioned. Jaegwon Kim, in particular, has argued that every version of non-reductive physicalism is committed to downward causation. But the nature action, I will argue, allows us to avoid this commitment.

This paper is about a puzzle which lies at the heart of contemporary physicalist theories of mind. On the one hand, the original motivation for physicalism was the need to explain the place of mental causation in the physical world. On the other hand, physicalists have recently come to see the explanation of mental causation as one of their major problems. But how can this be? I-low can it be that physicalist theories still have a problem explaining something which their physicalism was intended to explain in the first place? lf physicalism is meant to be an explanation of mental causation, then why should it still face the problem of mental causation? Disentagling this puzzle will cast light both on the recent mental causation debate and on physicalism itself. We can make a broad distinction between those forms of physicalism which identify mental and physical items and those which claim that there is some weaker relation of ’constitution’ between the mental and the physical. This latter view is now the orthodox version of physicalism. I shall argue that the problem of mental causation is only a problem for this orthodox physicalism, and not for identity theories. ln itself, this is not a particularly unusual claim. But I shall also argue that the real lesson of the mental causation debate is that orthodox physicalism is either unstable or unmotivated. It is unstable because (unlike the identity theories) it cannot reconcile mental causation with its other physicalist assumptions. It is unmotivated because in attempting to solve this mental causation problem, orthodox physicalism typically abandons one (or more) of the assumptions which form part of the original motivation for physicalism. To establish this, I need to explain (a) the nature of the arguments for physicalism, (b) the problem of mental causation, and (c) the standard solutions to the problem. These three tasks will form the main substance of this paper. But first I need to make some preliminary remarks about physicalism..

Given some reasonable assumptions concerning the nature of mental causation, non-reductive physicalism faces the following dilemma. If mental events cause physical events, they merely overdetermine their effects (given the causal closure of the physical). If mental events cause only other mental events, they do not make the kind of difference we want them to. This dilemma can be avoided if we drop the dichotomy between physical and mental events. Mental events make a real difference if they cause actions. But actions are neither mental nor physical events. They are realized by physical events, but they are not type-identical with them. This gives us non-reductive physicalism without downward causation. The tenability of this view has been questioned. Jaegwon Kim, in particular, has argued that non-reductive physicalism is committed to downward causation. Appealing to the nature of actions, I will argue that this commitment can be avoided.

In this paper I argue that the problem of mental causation can be solved by distinguishing between classificatory mental properties, like being a pain, and instances of those properties.Antireductive physicalism allows only that the former be irreducibly mental. Consequently, properties like being a pain cannot have causal commerce with the physical without violating causal closure. But instances of painfulness, according to the token identity thesis, are identical with various physical tokens and can therefore have causal efficacy in the physical world. Since we expect particular mental phenomena, not types or classes of mental phenomena to be involved in causal interactions, it is argued that antireductive physicalism can explain satisfactorily mental causation, despite the protests of Kim, Sosa, Honderich, and others. Being a mental state of a certain sort may have no causal efficacy, but the intentional and phenomenal properties of such states should, if my argument is correct.

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.
