Type Physicalism and Causal Exclusion
Journal of Philosophical Research, 2013
Concerns about the physical causally excluding the mental have persistently plagued non-reductive physicalism. Yet it is standardly assumed that the exclusion problem does not apply to reductive type physicalism. Here, I challenge this widely accepted advantage of type physicalism over non-reductive physicalism in avoiding the causal exclusion of the mental. In particular, I focus on Jaegwon Kim’s influential version of the causal exclusion argument, i.e. his supervenience argument. I argue that the generalizability of the supervenience argument, combined with type physicalism’s incompatibility with fundamental mental properties, undermines type physicalism’s advantage.
Two Myths of Psychophysical Reductionism
Open Journal of Philosophy, 2012
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 and that it is driven by two implausible justifications. One is “Edward’s dictum”, which is alien to non-reductive physicalism and should be rejected. The other is by endorsement of Papineau’s conception of the physical, immanent in Papineau’s causal argument. This argu- ment 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, leaving Papineau’s causal argument and Kim’s CEA without a reductive physicalist conclusion of philosophical interest.
A reductive type physicalist account of psychology
The appearance of multiple realization of the special sciences kinds by physical kinds can be fully explained within a type-identity reductive physicalist framework, based on recent findings in the foundations of statistical mechanics (see Hemmo and Shenker 2012, 2016). This has been shown in Hemmo and Shenker (paper presented at PSA 2016). However, while this account is available for special sciences like biology and thermodynamics, it is unavailable for psychology. Therefore the only coherent physicalist account of psychology is a type-type identity account. The so-called “non reductive” physicalism turns out to be an incoherent idea, and functionalism and supervenience cannot salvage it. At the same time, within a type-identity account properly understood one can give a full account of the anomaly of psychology and understand in what sense the special sciences - including psychology - are autonomous.
Inquiry
The exclusion problem is meant to show that non-reductive physicalism leads to epiphenomenalism: if mental properties are not identical with physical properties, then they are not causally efficacious. Defenders of a difference-making account of causation suggest that the exclusion problem can be solved because mental properties can be difference-making causes of physical effects. Here, we focus on what we dub an incompatibilist implementation of this general strategy and argue against it from a non-reductive physicalist perspective. Specifically, we argue that incompatibilism undermines either the non-reductionist or the physicalist aspirations of non-reductive physicalism.
Why incompatibilism about mental causation is incompatible with non-reductive physicalism

A grounding physicalist solution to the causal exclusion problem
Synthese , 2020
Remember how Kim (Philos Perspect 3:77-108, 1989, in: Heil and Mele (eds) Mental causation, Clarendon Press, Oxford, 1993b) used to argue against non-reductive physicalism to the effect that it cannot accommodate the causal efficacy of the men-tal? The argument was that if physicalists accept the causal closure of the physical, they are faced with an exclusion problem. In the original version of the argument, the dependence holding between the mental and the physical was cashed out in terms of supervenience. Due to the work or Fine (Philos Perspect 8:1-16, 1994) and others, we have since come to realize that modal notions are not well-suited to perform the work of properly characterizing dependence. As a consequence of this, an increasingly larger community of contemporary metaphysicians prefer to spell out mental-physical dependence in terms of a non-causal and non-reductive notion called grounding, which is intended to target a particular sort of metaphysical relation that takes us from ontologically less fundamental features of the world to that which is more fundamental. In this paper I join forces with those who think that this shift in focus is on the right track. More specifically, I will argue that the grounding physicalist can solve the exclusion problem in a way that is preferable to the supervenience-based nonreductive physical-ist solution, as well as in a way that is compatible with the externalist picture of the mental.
The Supervenience Argument Against Non-Reductive Physicalism
In Michael Bruce & Steven Barbone (eds.), Just the Arguments: 100 of the Most Important Arguments in Western Philosophy. Wiley-Blackwell., 2011
This short paper is a "quick and dirty" introduction for non-philosophers (with some background in propositional logic) to Jaegwon Kim's famous supervenience argument against non-reductive physicalism (also known as the exclusion problem). It motivates the problem of mental causation, introduces Kim's formulation of the issue centered around mind-body supervenience, presents the argument in deductive form, and makes explicit why Kim concludes that vindicating mental causation demands a reduction of mind.
