The Exclusion Problem

Many philosophers argue that exclusion arguments cannot exclude non-reductionist physicalist mental properties from being causes without excluding properties that are patently causal as well. List and Stoljar (2017) recently argued that a similar response to exclusion arguments is also available to dualists, thereby challenging the predominant view that exclusion arguments undermine dualist theories of mind. In particular, List and Stoljar maintain that exclusion arguments against dualism require a premise that states that, if a property is metaphysically distinct from the sufficient (...) cause of an effect, this property cannot be a cause of that effect. I argue that this premise is indeed likely to exclude patently causal properties, but that exclusion arguments against dualism do not require this premise. The relation that enables metaphysically distinct properties to cause the same effect in the relevant way turns out to be tighter than the relation typically posited between dualist conscious properties and their underlying physical properties. It is therefore still plausible that the latter causally exclude the former and that compelling exclusion arguments against dualism can be formulated by using a weaker exclusion premise. I conclude by proposing such a formulation. (shrink)

ABSTRACT A popular strategy for 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 causal efficacy of the wrong dispositions is secured.

Jaegwon Kim’s views on mental causation and the exclusion argument are evaluated systematically. Particular attention is paid to different theories of causation. It is argued that the exclusion argument and its premises do not cohere well with any systematic view of causation.

Sophie Gibb has recently invented a very interesting strategy against Kim’s causal exclusion argument. This strategy adopts the powers theory of causation and an interpretation of mental causation in terms of double prevention. Gibb’s strategy results both in invalidating the principle of the causal closure of the physical domain in most of its formulations and in disarming the argument in question. In my paper, I present a general procedure for the opponents of reductive physicalism which enables them to _grapple successfully_ (...) with the mentioned principle. I also argue that although it could be possible to adopt Gibb’s strategy as a part of this procedure, there is a simpler one to obtain a similar outcome. This strategy is mainly based on Uwe Meixner’s causal argument against physicalism and it leads to the conclusion that if one accepts the principle of sufficient cause, then one should reject the principle of causal closure in the light of some empirical data. This alternative proposal is more attractive than Gibb’s solution, since it is independent of any conception of causation, does not make any distinction between causal relevance and causal efficacy, and does not refer to the notion of _double prevention_.

I outline two ways of reading what is at issue in the exclusion problem faced by non-reductive physicalism, the “vertical” versus “horizontal”, and argue that the vertical reading is to be preferred to the horizontal. I discuss the implications: that those who have pursued solutions to the horizontal reading of the problem have taken a wrong turn.

The purpose of this paper is to address a well-known dilemma for physicalism. If mental properties are type identical to physical properties, then their causal efficacy is secure, but at the cost of ruling out mentality in creatures very different to ourselves. On the other hand, if mental properties are multiply realizable, then all kinds of creatures can instantiate them, but then they seem to be causally redundant. The causal exclusion problem depends on the widely held principle that realized properties (...) inherit their causal powers from their realizers. While this principle holds for functional realization, it fails on a broader notion of realization that permits the realization of complex qualitative properties such as spatial and temporal patterns. Such properties are best seen as dependent powerful qualities, which have their causal roles in virtue of being the qualities they are, and do not inherit powers from their realizers. Recent studies have identified one such property—neural synchrony—as a correlate of consciousness. If synchrony is also partially constitutive of consciousness, then phenomenal properties are both multiply realizable and causally novel. I outline a version of representationalism about consciousness on which this constitution claim holds. (shrink)

How should thought and consciousness be understood within a view of the world as being through-and-through physical? Many philosophers have proposed non-reductive, levels-based positions, according to which the physical domain is fundamental, while thought and consciousness are higher-level processes, dependent on and determined by physical processes. In this book, Kevin Morris's careful philosophical and historical critique shows that it is very difficult to make good metaphysical sense of this idea - notions like supervenience, physical realization, and grounding all fail to (...) articulate a viable non-reductive, levels-based physicalism. Challenging assumptions about the mind-body problem and providing new perspectives on the debate over physicalism, this accessible and comprehensive book will interest scholars working in metaphysics, philosophy of mind, and philosophy of science.

According to Peter van Inwagen, C. S. Lewis failed in his attempt to undermine naturalism with his Argument from Reason. According to van Inwagen, Lewis provides no justification for his central premise, that naturalism is inconsistent with holding beliefs for reasons. What is worse, van Inwagen argues that the main premise in Lewis's argument from reason is false. We argue that it is not false. The defender of Lewis's argument can make use of the problem of mental causal drainage, a (...) longstanding issue in philosophy of mind, to show how van Inwagen's objection fails. (shrink)

Mind and the Causal Exclusion Problem The causal exclusion problem is an objection to nonreductive physicalist models of mental causation. Mental causation occurs when behavioural effects have mental causes: Jennie eats a peach because she wants one; Marvin goes to Harvard because he chose to, etc. Nonreductive physicalists typically supplement adherence to mental causation with … Continue reading Mind and the Causal Exclusion Problem →.

Some recent arguments defending the genuine causal efficacy of the mental have been relying on empirical research on neuroprosthetics. This essay presents a critical analysis of these arguments. The problem of mental causation, and the basic idea and results of neuroprosthetics are reviewed. It is shown how appealing to the research on neuroprosthetics can be interpreted to give support to the idea of mental causation. However, it does so only in a rather deflationary sense: by holding the mental identical with (...) the neural. So contrary to what the arguments have been assuming, neuroprosthetics cannot be used to argue for nonreductive physicalism. It can rather be taken to illustrate just the opposite: how the mental and the physical are identical. (shrink)

In this paper we explore Jaegwon Kim's principle of explanatory exclusion. Kim's support for the principle is clarified and we critically evaluate several versions of the dual explananda response authors have offered to undermine it. We argue that none of the standard versions of the dual explananda reply are entirely successful and propose an alternative approach that reveals a deep tension in Kim's metaphysics. We argue that Kim can only retain the principle of explanatory exclusion if he abandons his longstanding (...) critique of nonreductive physicalism. (shrink)

According to James Woodward’s influential interventionist account of causation, X is a cause of Y iff, roughly, there is a possible intervention on X that changes Y. Woodward requires that interventions be merely logically possible. I will argue for two claims against this modal character of interventions: First, merely logically possible interventions are dispensable for the semantic project of providing an account of the meaning of causal statements. If interventions are indeed dispensable, the interventionist theory collapses into a counterfactual theory (...) of causation. Thus, the interventionist theory is not tenable as a theory of causation in its own right. Second, if one maintains that merely logically possible interventions are indispensable, then interventions with this modal character lead to the fatal result that interventionist counterfactuals are evaluated inadequately. Consequently, interventionists offer an inadequate theory of causation. I suggest that if we are concerned with explicating causal concepts and stating the truth-conditions of causal claims we best get rid of Woodwardian interventions. (shrink)

If a woman in the audience at a presentation raises her hand, we would take this as evidence that she intends to ask a question. In normal circumstances, we would be right to say that she raises her hand because she intends to ask a question. We also expect that there could, in principle, be a causal explanation of her hand’s rising in purely physiological terms. Ordinarily, we take the existence and compatibility of both kinds of causes for granted. But (...) this can come to seem strange. When we imagine tracking the physiological process that culminates in her hand’s rising, it is hard to find a purchase for her intention. The physiological process seems not to need assistance from her intention in order to get where it’s going, chugging along as it does according to principles that appear to have very little in common with ordinary psychological ones. The presumed self-sufficiency of physiological processes can, in a similar fashion, appear to muscle psychological states quite generally out of the causal picture. (shrink)

This article aims to provide a brief overview of mental causation problem and its current proposed solutions. Indeed, mental causation turns out as one of the most difficult philosophical conundrums in contemporary philosophy of mind. In the first two sections, we offer an outline of the problem and the philosophical debate about it, and show that mental causation problem is pivotal within the contemporary philosophy of mind. In the third section, we focus on the most popular models of mental causation, (...) namely Kim's and Davidson's accounts, also discussing the objections raised against them. In the final section, we take into consideration some recent proposals poised to solve the mental causation problem, including powerism. Given the logical and metaphysical plausibility of almost all these different options, our conclusion is that mental causation is still an open problem and it is far from being resolved. (shrink)

In this paper, we examine the causal framework within which integrated information theory of consciousness makes it claims. We argue that, in its current formulation, IIT is threatened by the causal exclusion problem. Some proponents of IIT have attempted to thwart the causal exclusion problem by arguing that IIT has the resources to demonstrate genuine causal emergence at macro scales. In contrast, we argue that their proposed solution to the problem is damagingly circular as a result of inter-defining information and (...) causation. As a solution, we propose that IIT should adopt the specific interventionist causal framework that we offer and show how IIT can harness this interventionist framework to avoid the causal exclusion problem. We demonstrate how our argument remains fully compatible with the methodology, empirical data, and conceptual aims of the theory. (shrink)

The relationship between psychological states and the brain remains an unresolved issue in philosophy of psychology. One appealing solution that has been influential both in science and in philosophy is Dennett’s concept of the intentional stance, according to which beliefs and desires are real and objective phenomena, but not necessarily states of the brain. A fundamental shortcoming of this approach is that it does not seem to leave any causal role for beliefs and desires in influencing behavior. In this paper, (...) I show that intentional states ascribed from the intentional stance should be seen as real causes, develop this to an independently plausible ontological position, and present a response to the latest interventionist causal exclusion worries.

Nonreductive physicalism faces serious problems regarding causal exclusion, causal heterogeneity, and the nature of realization. In this paper I advance solutions to each of those problems. The proposed solutions all depend crucially on embracing modal counterpart theory. Hence, the paper’s thesis: counterpart theory saves nonreductive physicalism. I take as my inspiration the view that mental tokens are constituted by physical tokens in the same way statues are constituted by lumps of clay. I break from other philosophers who have pursued this (...) line, however, in that I hold that constitution is identity. Much of the value of the comparison to statues and lumps is that it calls to mind the resources used to defend constitution-as-identity, most notably that of counterpart theory. Along the way, I discuss the virtues of a trope ontology, modal objections to token identity theories, the prospects of conditional analyses of causal powers, the subset account of realization, and the grounding problem. I also endorse a novel, empirical argument in favor of counterpart theory. (shrink)

Recently, Kroedel and Schulz have argued that the exclusion problem—which states that certain forms of non-reductive physicalism about the mental are committed to systematic and objectionable causal overdetermination—can be solved by appealing to grounding. Specifically, they defend a principle that links the causal relations of grounded mental events to those of grounding physical events, arguing that this renders mental–physical causal overdetermination unproblematic. Here, we contest Kroedel and Schulz’s result. We argue that their causal-grounding principle is undermotivated, if not outright false. (...) In particular, we contend that the principle has plausible counterexamples, resulting from the fact that some mental states are not fully grounded by goings on ‘in our heads’ but also require external factors to be included in their full grounds. We draw the sceptical conclusion that it remains unclear whether non-reductive physicalists can plausibly respond to the exclusion argument by appealing to considerations of grounding. (shrink)

This paper argues that a certain kind of substance dualism can adopt the ‘Compatibilist’ solution to the problem of causal exclusion. After sketching a non-Cartesian substance dualism akin to E.J. Lowe’s account, 5-23, 2006, 2008) and considering its shortcomings with respect to mental causation in section one, section two outlines an alternative account of mental causation and argues that this account solves the exclusion problem. Finally, section three considers a challenge to the proposed solution. With the exception of Lowe’s efforts, (...) very little in defense of substance dualist mental causation is to be found in the recent philosophical literature. (shrink)

This paper argues that two principles held by many metaphysicians and philosophers of mind are inconsistent: there is no systematic overdetermination, and some causal effects are also determined by their metaphysical grounds. Call this “The Problem of Secondary Effects.” After introducing the problem and noting philosophical theories that face it, the paper offers further clarification by considering three potential strategies for solving it. All fail. An approach that sacrifices ‘secondary effects’ is briefly sketched as a solution.

This work makes the case for a variant of panpsychism with an idealist metaphysic. It does not deny the concrete existence of any entities discoverable from commonplace experience or by science (such as cats, rocks, molecules and quarks), but argues that all true entities (the entire furniture of the universe) are in essence nothing over and above centres of experience that can perceive one another and act on their percepts. All physical properties and laws reduce without remainder to mental dittos. (...) The system gives a lucid account of mental causation. The book critiques physicalism as obscure, perhaps even incoherent, and defends libertarian free will. (shrink)

Instances of many supervenient properties have physical effects. In particular, instances of mental properties have physical effects if non-reductive physicalism is true. This follows by a straightforward argument that assumes a counterfactual criterion for causation. The paper presents that argument and discusses several issues that arise from it. In particular, the paper addresses the worry that the argument shows too many supervenient property-instances to have physical effects. The argument is also compared to a similar argument that has been suggested by (...) Lei Zhong and is shown to be superior to the latter. (shrink)

I introduce and argue for a Priority Principle, according to which we exemplify certain of our mental properties in the primary or non-derivative sense. I then apply this principle to several debates in the metaphysics and philosophy of mind.

Russellian Monism, the view that phenomenal or protophenomenal properties serve as the categorical grounds of physical dispositions, has increasingly been thought to enjoy an advantage over traditional property dualism in that it avoids epiphenomenalism. This paper argues otherwise. Russellian Monism faces problems with mental causation that parallel those of traditional dualism. The best it can hope for is that phenomenal properties are causally relevant, but not in virtue of their phenomenality.

Karen Bennett (2003, 2008) has argued for and developed a way of defending a non-reductive physicalist solution to Jaegwon Kim's Causal Exclusion Argument. She argues that mental and physical causes can both be sufficient causes of the same event without being classified as overdetermining causes. This strategy, however, is only available to physicalists. I argue that dualists can adopt or adapt her strategy.

The problem of mental causation results from some unwarranted metaphysical assumption: the Principle of Nomological Character of Causality. However, there is little reason to understand causation in the manner required to make NCC work. The motivation for the demand for laws in action explanations stems at least in part from the fact that the laws cited in explanations are the laws that subsume events in naturalistic causal relations. By rejecting the idea that causal explanation is causal because it is grounded (...) in natural causal relations, the motivation for requiring laws in explanations disappears. I claim that this is the reason why we need to pay attention to our practice and explanatory strategies. By rejecting NCC we can in fact arrive at a sustainable, defensible and rewarding account of mental causation. The primacy of explanatory practice over the ontological commitment reverses such that an explanation is causal if we accept it as such. By reinterpreting the notion of causation we regain the causal efficacy of the mental. We look to a theory of intentional action for help in answering the problem of mental causation. In this work I provide a novel conception of intentional action by distinguishing normative reasons from motivating reasons. The proposal recommends itself as being capable of dealing with many problems, including the problems raised by unintended side effects and lucky actions. More importantly, the proposal is able to deal with the problem of causal deviance and consequently is promising in that it avoids epiphenomenalism of mental properties. I conclude the criteria for intentional action must be wide enough to include the normative perspectives of a third-point of view as well as the psychological perspectives. (shrink)

In many biological experiments, due to gene-redundancy or distributed backup mechanisms, there are no visible effects on the functionality of the organism when a gene is knocked out or down. In such cases there is apparently no counterfactual dependence between the gene and the phenotype in question, although intuitively the gene is causally relevant. Due to relativity of causal relations to causal models, we suggest that such cases can be handled by changing the resolution of the causal model that represents (...) the system. By decreasing the resolution of our causal model, counterfactual dependencies can be established at a higher level of abstraction. By increasing the resolution, stepwise causal dependencies of the right kind can serve as a sufficient condition for causal relevance. Finally, we discuss how introducing a temporal dimension in causal models can account for causation in cases of non-modular systems dynamics. (shrink)
