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.

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.

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.

Ausonio Marras has argued that Jaegwon Kim's principle of explanatory exclusion depends on an implausibly strong interpretation of explanatory realism that should be rejected because it leads to an extensional criterion of individuation for explanations. I examine the role explanatory realism plays in Kim's justification for the exclusion principle and explore two ways in which Kim can respond to Marras's criticism. The first involves separating criteria for explanatory truth from questions of explanatory adequacy, while the second appeals to Kim's fine-grained theory of events. I argue that the first response is unconvincing on its own but when coupled with the second might provide a viable way for Kim to avoid Marras's criticism. However, I show that the second strategy is weak from a polemical point of view because Kim's theory of events already assumes what the principle of explanatory exclusion was introduced to establish: the falsity of nonreductive physicalism.

Judgments of explanatory exclusion are a necessary part of the explanatory practice of any historian or social scientist. In this article, the author argues that all explanatory exclusion results from mutual explanatory incompatibility of some sort. Different types of exclusion arise primarily as a result of the different elements composing "an explanation." Of most philosophical interest are judgments of explanatory exclusion resulting from the incompatibility of explanatory relevance claims. The author demonstrates that an ontic theory of explanation is necessary to make sense of this type of exclusion and in so doing develops an analysis similar to Jaegwon Kim’s well-known analysis of explanatory exclusion. To conclude, the author demonstrates the differences and connections between Kim’s analysis and his own. Key Words: explanation • social science • history • exclusion • compatibility.

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..

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

Jaegwon Kim’s principle of Explanatory Exclusion says there can be no more than a single complete and independent explanation of any one event. Accordingly, if we have a complete neurological explanation for some piece of human behavior, the mental explanation must either be excluded, or it must not be distinct from the neurological explanation. Jaegwon Kim argues that mental explanations are not distinct from neurological explanations on account of the fact that they refer to the same objective causal relation between events. A number of critics have argued that this extensional model of explanatory individuation allows for too many descriptions to state the same explanation. In this paper I consider, and ultimately reject, a possible response to these critics called the Constitutive Property Reply.
