The paper defends Humean approaches to autonomous mental causation against recent attacks in the literature. One important criticism launched at Humean approaches says that the truth-makers of the counterfactuals in question include laws of nature, and there are laws that support physical-to-physical counterfactuals, but no laws in the same sense that support mental-to-physical counterfactuals. This paper argues that special science causal laws and physical causal laws cannot be distinguished in terms of degrees of strictness. It follows that mental-to-physical counterfactuals are (...) supported—or not supported—by laws in just the same way as are physical-to-physical counterfactuals. (shrink)

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)

In Zhong (Philos Phenomenol Res 83:129–147, 2011; Analysis 72:75–85, 2012), I argued that, contrary to what many people might expect, the counterfactual theory of causation will generate (rather than solve) the exclusion problem. Recently some philosophers raise an incisive objection to this argument. They contend that my argument fails as it equivocates between different notions of a physical realizer (see Christensen and Kallestrup in Analysis 72:513–517, 2012). However, I find that their criticism doesn’t threaten the central idea of my view. (...) In this paper, I make two separate responses that appeal to two unequivocal notions of physical realizers, respectively. I aim to show that a modified argument that uses either notion would work. (shrink)

Many philosophers insist that the most plausible solution to the exclusion problem is to adopt the so-called ‘autonomy approach’, which denies either upward or downward causation between mental and physical properties. But the question of whether the autonomy approach is compatible with respectable theories of causation has seldom been discussed in the literature. This paper considers two influential theories of causation, the counterfactual account and the regularity account. I argue that neither the counterfactual theory nor the regularity theory can support (...) the autonomy approach – while the counterfactual approach fails to block downward causation, the regularity approach is unable to refute upward causation.

The overdetermination problem has long been raised as a challenge to nonreductive physicalism. Nonreductive physicalists have, in various ways, tried to resolve the problem through appeal to counterfactuals. This essay does two things. First, it takes up the question whether counterfactuals can yield an appropriate notion of causal redundancy and argues for a negative answer. Second, it examines how this issue bears on the mental causation debate. In particular, it considers the argument that the overdetermination problem simply does not arise (...) on a dependency conception of causation and shows why this idea, though initially appealing, does not address the real problem. As the essay shows, the idea derives its spurious plausibility from the fact that the dependency conception cannot even make sense of our pretheoretic idea of causal redundancy. The essay concludes by briefly discussing a possible picture of mental causation that suggests itself in light of these results. (shrink)

This paper explores and defends the idea that mental properties and their physical bases jointly cause their physical effects. The paper evaluates the view as an emergentist response to the exclusion problem, comparing it with a competing nonreductive physicalist solution, the compatibilist solution, and argues that the joint causation view is more defensible than commonly supposed. Specifically, the paper distinguishes two theses of closure, Strong Closure and Weak Closure, two causal exclusion problems, the overdetermination problem and the supervenience problem, and (...) argues that emergentists can avoid the overdetermination problem by denying Strong Closure and respond to the supervenience problem by accepting the joint causation view.

The present essay argues against the view that Santayana’s philosophy can unproblematically be classified as epiphenomenalist. To this end, it examines the central tenets that provide the foundation for his position on metal causation as developed in Scepticism and Animal Faith. This analysis shows that a range of positions are available to Santayana that are compatible with his prohibition on invoking ideas as motor causes, perhaps even demanded by it. While Santayana is consistent in denying that ideas are causes, taken (...) in the usual sense of efficient or motor causes, he does not clearly deny that they are necessary conditions for some behavioral effects. The essay then responds to the objection that we should sooner reject the claim that essences are necessary conditions for action than attempt to argue for the compatibility of this claim with the claim that essences are causally inert. It is argued that Santayana is not alone in considering these assertions compatible, and therefore his position should be classed alongside those of contemporary philosophers who also assert their compatibility. The essay closes by examining some similarities between Santayana’s view and those of contemporary compatibilists. (shrink)

This paper examines Jaegwon Kim's Supervenience Argument (SA) against nonreductive physicalism, concentrating on Kim's response to two of the most important objections against the SA: First, the Overdetermination Argument, according to which Kim has no convincing argument against the possibility that mental causation might be a case of genuine or systematic overdetermination; second, the Generalization Argument, according to which the SA would entail that causation at any level gives way to causation at the next lower level, thereby leading to an (...) untenable all-encompassing epiphenomenalism. It is argued that as of yet, Kim has failed to develop a coherent overall position, since various moves he makes in response to these criticisms are strangely at odds with other parts of his philosophical position. (shrink)

In Elder-Vass’s response to my critical discussion of his social ontology, it is maintained (1) that a social object is not identical with but is merely composed of its suitably interrelated parts, (2) that a social object is necessarily indistinguishable in terms of its causal capacities from its interrelated parts, and (3) that ontological individualism lacks an adequate ontological justification. In this reply, I argue that in view of (1) the so-called redescription principle defended by Elder-Vass ought to be reformulated (...) and renamed; that the conjunction of (1) and (2) renders social objects causally redundant; and that ontological individualism can be coherently formulated and theoretically justified within Elder-Vass’s own metaphysics of objects with causal powers. (shrink)

The paper aims to demonstrate the possibility of consistently accepting the existence of effective mental causality in the fundamentally physical world. We suppose that the concept of causality in J. Kim’s exclusion argument against mental causation, which implies а generative conception of causal relations, can be revised taking into account the specificity of the multilevel organization of living objects. Rejection of the mechanistic model of causality as a linear process, allows you to maintain commitment to the principle of causal closure (...) of the physical world and at the same time explain how top-down causality at the macro level is possible. For this, we use the model of a fractal tree of causal chains by J. Lowe, in which mental causality plays the role of an indirect cause of a fact. We carry out a meaningful distinction between the causality of facts and events by resorting to the multilevel model of J. Ellis, in which mental causality can be considered as a macro-level fact that has a selective effect on physical events of lower levels, taking into account a wide environmental context. (shrink)

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)

Loewer (in: Physicalism and its discontents, 2001; Philos Phenomenol Res 65:655–663, 2002; in: Contemporary debates in philosophy of mind, 2007) has argued that the nonreductive physicalist should respond to the exclusion problem by endorsing the overdetermination entailed by their view. Kim’s (Physicalism, or something near enough, 2005; in: Contemporary debates in the philosophy of mind, 2007) argument against this reply is based on the premise that mental causation must be a productive relation in order to sustain human agency. In this (...) paper, I challenge the premise that mental causation is a productive relation by appealing to the underlying double prevention structure of the physiological mechanisms of human action. Since the causal pathways from an agent’s mental events to bodily movement involves an absence, mental causation is not productive. This places Kim in a troublesome dilemma in his debate with Loewer: either surrender mental causation or deny that causation is a productive relation. With the support offered for productive mental causation undermined, responses to the exclusion problem based on accepting overdetermination remain viable options for the nonreductive physicalist.

This article considers three views about which properties are genuine. According to the first view, we should look to successful commonsense and scientific explanations in determining which properties are genuine. On this view, predicates that figure in such explanations thereby pick out genuine properties. According to the second view, the only predicates that pick out genuine properties are those that figure in our best scientific explanations. On this view, predicates that figure in commonsense explanations pick out genuine properties only if (...) such explanations are vindicated by the sciences. According to the third view, the only genuine properties are the fundamental, microphysical ones. On this view, although there are “higher-level” predicates that figure in true commonsense and scientific explanations, there are no “higher-level” properties corresponding to such predicates. The article argues that the third view is superior to the others. (shrink)

As conceived by Kim, the causal exclusion argument targets all forms of nonreductive physicalism equally, but by restricting its focus to functionalist varieties of nonreductivism, I am able to develop a version of the argument that has a number of virtues lacking in the original. First, the revised argument has no need for Kim’s causal exclusion principle, which many find dubious if not simply false. Second, the revised argument can be adapted to either a production-based conception of causation, as Kim (...) himself favors, or to any of a number of dependence-based conceptions, like the ones favored by many of Kim’s critics. And, finally, the revised argument does not have the objectionable consequence that all so-called higher-level properties are epiphenomenal, for it does not generalize in the way that Kim’s original version of the argument arguably does. Nor does it concede much to narrow the scope of the argument in the way proposed. Those who adopt nonreductive theories of mind do so, by and large, on the strength of functionalist arguments for the multiple realizability of mental states. If functionalism entails that mental properties are epiphenomenal, this thus deals a critical, if not quite fatal, blow to nonreductivism. (shrink)

I argue for the epiphenomenality of functional properties by means of thought experiments and general principles. General principles suggest that an object’s causal powers nomologically supervene on its intrinsic properties and that its functional role does not. This implies that it is possible for an object to lose its functional role without undergoing any change to its intrinsic properties or causal powers. Nor is it difficult to conceive of such scenarios. Various thought experiments are introduced for just this purpose. But (...) properties that can vary independently of an object’s causal powers in this way are epiphenomenal, for their instantiation by an object at a time makes no difference to the causal processes the object is involved in at that time. The same processes would have occurred even if such properties hadn’t been instantiated. The intrinsicness thesis is controversial, but it is not controversial that it is true of productive causation, and many believe that productive causation is the only form of mental causation worth having. Nevertheless, in the paper’s final section I consider dependence-based accounts of causation, which do not presuppose the intrinsicness of causal powers, and show that they too have difficulties accounting for the efficacy of functional properties. (shrink)

A popular approach in philosophy, the so-called Canberra Plan, is critically scrutinized. Two aspects of this research program, the formal and the informal program, are distinguished. It is argued that the formal program runs up against certain serious technical problems. It is also argued that the informal program involves an unclear leap at its core. Consequently, it is argued that the whole program is much more problematic than its advocates recognize.

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.

Identity theories are those that hold that 'sensations are brain processes'. In particular, they hold that mental/psychological state kinds are identical to brain/neuroscientific state kinds. In this paper, I isolate and explain some of the key features of contemporary identity theories. They are then contrasted with the main live alternatives by means of considering the two most important lines of objection to identity theories.

The type-type reductive identity of the mental to the physical was once the dominant position in the mental causation debate. In time this consensus was overturned, largely due to its inability to handle the problem of multiple realizability. In its place a nonreductive position emerged which often included an adherence to functionalism. Functionalism construes mental properties as functional states of an organism, which in turn have specific physical realizers. This nonreductive form of functionalism, henceforth called role functionalism, has faced a (...) number of criticisms itself. Chief among these is the concern that the realizer of the functional role is causally sufficient, so the role property does not make a contribution of its own. In this paper I argue that there is a way for unreduced functional properties to play a role after all. This is done by conceiving of functional properties as higher level functional properties of a macro system which determine that its realizers will play the roles that they play. (shrink)

Qualia epiphenomenalism is the view that qualitative properties of events, such as the raw feel of tastes or painfulness, lack causal efficacy. One common objection to qualia epiphenomenalism is the epistemic argument, which states that this loss of causal efficacy undermines our capacity to know about these epiphenomenal qualitative properties. A number of rejoinders have been offered up to insulate qualia epiphenomenalism from the epistemic argument. In this paper I consider and ultimately reject two such replies, namely, the common underlying (...) cause reply and the appeal to physical-effect epiphenomenalism.

According to proponents of the causal exclusion problem, there cannot be a sufficient physical cause and a distinct mental cause of the same piece of behaviour. Increasingly, the causal exclusion problem is circumvented via this compatibilist reasoning: a sufficient physical cause of the behavioural effect necessitates the mental cause of the behavioural effect, so the effect has a sufficient physical cause and a mental cause as well. In this paper, I argue that this compatibilist reply fails to resolve the causal (...) exclusion problem. (shrink)

Jaegwon Kim argues that unreduced mental causes are excluded from efficacy because physical causes are sufficient in themselves. One response to this causal exclusion argument is to embrace some form of overdetermination. In this paper I consider two forms of overdetermination. Independent overdetermination suggests that two individually sufficient causes bring about one effect. This model fails because the sufficiency of one cause renders the other cause unnecessary. Dependent overdetermination suggests that a physical cause is necessary and sufficient for a given (...) effect, but it necessitates a mental cause of the effect as well. This model fails because the necessity of the mental cause renders the physical cause individually insufficient. (shrink)

Nonreductive physicalists endorse the principle of mental causation, according to which some events have mental causes: Sid climbs the hill because he wants to. Nonreductive physicalists also endorse the principle of physical causal completeness, according to which physical events have sufficient physical causes: Sid climbs the hill because a complex neural process in his brain triggered his climbing. Critics typically level the causal exclusion problem against this nonreductive physicalist model, according to which the physical cause is a sufficient cause of (...) the behavioural effect, so the mental cause is excluded from causally influencing Sid’s behaviour. In this paper I demonstrate how numerous nonreductive physicalists have responded to the causal exclusion problem by weakening the principle of physical causal completeness in numerous ways. The result: either numerous nonreductive physicalist solutions fail on account of the fact that they do not satisfy a robustly defined principle of physical causal completeness, or there is an accelerating trend of solving the causal exclusion problem by suitably weakening the principle of physical causal completeness.

Sydney Shoemaker has proposed a new definition of `realization’ and used it to try to explain how mental events can be causes within the framework of a non-reductive physicalism. I argue that it is not actually his notion of realization that is doing the work in his account of mental causation, but rather the assumption that certain physical properties entail mental properties that do not entail them. I also point out how his account relies on certain other controversial assumptions, including (...) analytical filler-functionalism for mental properties, and the assumption that causes must be proportional to their effects. I conclude by pointing out that Shoemaker has provided no explanation of why, on his view, certain physical properties entail mental properties. (shrink)

Recent worries about possible epiphenomenalist consequences of nonreductive materialism are misplaced, not, as many have argued, because nonreductive materialism does not have epiphenomenalist implications but because the epiphenomenalist implications are actually virtues of the theory, rather than vices. It is only by showing how certain kinds of mental properties are causally impotent that cognitive scientific explanations of mentality as we know them are possible.

Abstract: I offer a novel objection to Jaegwon Kim's Supervenience Argument. I argue that the Supervenience Argument relies upon an untenable conception of the base physical properties upon which mental properties are supposed to supervene: the base properties are required to be both ordinary physical/causal properties and also unconditionally sufficient for the properties that they subvene. But these requirements are mutually exclusive; as a result, at least two premises in the Supervenience Argument are false. I argue that this has disruptive (...) consequences both for the reductive position that Kim defends and the non-reductive position that he attacks. Neither side in the debate over the status of functionally conceived mental properties comes out unscathed. (shrink)

Counterfactual conditionals have been appealed to in various ways to show how the mind can be causally efficacious. However, it has often been overestimated what the truth of certain counterfactuals actually indicates about causation. The paper first identifies four approaches that seem to commit precisely this mistake. The arguments discussed involve erroneous assumptions about the connection of counterfactual dependence and genuine causation, as well as a disregard of the requisite evaluation conditions of counterfactuals. In a second step, the paper uses (...) the insights of the foregoing analyses to formulate a set of counterfactuals-based conditions that are characterized as sufficient to establish singular causal claims. The paper concludes that there are ample reasons to believe that some mental events satisfy all these conditions with respect to certain further events and, hence, that mental events sometimes are causes.

In this reply, I argue that in view of the so-called redescription principle defended by Elder-Vass ought to be reformulated and renamed; that the conjunction of and renders social objects (...) causally redundant; and that ontological individualism can be coherently formulated and theoretically justified within Elder-Vass’s own metaphysics of objects with causal powers.

Kim's exclusion argument threatens to show that irreducible constituted objects are epiphenomenal. Kim's arguments are examined and found to be unconvincing; that a constituted cause requires its constituent to be a cause is not an adequate reason to reject the causation of the constituted object (event or property-instance). However, I introduce and argue for, the Causal Power Uniqueness Condition (CPUC). I argue that CPUC and the causal closure of the physical, implies that constituted objects or property-instances are not novel causal (...) powers. (shrink)

Intuitions play an important role in the debate on the causal status of high‐level properties. For instance, Kim has claimed that his “exclusion argument” relies on “a perfectly intuitive … understanding of the causal relation.” We report the results of three experiments examining whether laypeople really have the relevant intuitions. We find little support for Kim's view and the principles on which it relies. Instead, we find that laypeople are willing to count both a multiply realized property and its realizers (...) as causes, and regard the systematic overdetermination implied by this view as unproblematic. (shrink)

Concerns about ‘mental causation’ are concerns about how it is possible for mental states to cause anything to happen. How does what we believe, want, see, feel, hope, or dread manage to cause us to act? Certain positions on the mind-body problem—including some forms of physicalism—make such causation look highly problematic. This entry sketches several of the main reasons to worry, and raises some questions for further investigation.

Emergent properties are intended to be genuine, natural higher level causally efficacious properties irreducible to physical ones. At the same time they are somehow dependent on or 'emergent from' complexes of physical properties, so that the doctrine of emergent properties is not supposed to be returned to dualism. The doctrine faces two challenges: (i) to explain precisely how it is that such properties emerge - what is emergence; (ii) to explain how they sidestep the exclusion problem - how it is (...) that there is room for these properties to be causally efficacious, given the causal completeness of the physical. In this paper I explain how functional properties can meet both challenges. (shrink)

In this dissertation, I develop and defend a model of causation that allows for dualist mental causation in worlds where the physical domain is physically complete. In Part I, I present the dualist ontology that will be assumed throughout the thesis and identify two challenges for models of mental causation within such an ontology: the exclusion worry and the common cause worry. I also argue that a proper response to these challenges requires a thoroughly lightweight account of causation, i.e. an (...) account that allows for causes to be metaphysically distinct from the phenomena that produce or physically necessitate their effects. In Part II, I critically evaluate contemporary responses to these challenges from the philosophical literature. In particular, I discuss List and Stoljar’s criticism of exclusion worries, Kroedel’s alternative dualist ontology, concerns about the notion of causal sufficiency, and Lowe’s models of dualist mental causation. I argue that none of these proposals provide independent motivation for a thoroughly lightweight account of causation and therefore leave room for improvement. In the first four chapters of Part III, I develop a thoroughly lightweight model of causation, which builds on interventionist approaches to causation. First, I explain how so-called ‘holding fixed’-requirements in standard interventionist accounts stand in the way of dualist mental causation. I then argue that interventionist accounts should impose a robustness condition on causal correlations and that, with this condition in place, the ‘holding fixed’-requirements can be weakened such that they do allow for dualist mental causation. I dub the interventionist model with such weakened ‘holding fixed’-requirements ‘insensitive interventionism’, argue that it can counter the exclusion worry as well as the common cause worry, and explain under which circumstances it would predict there to be dualist mental causation. Importantly, these circumstances might, for all we know, hold in the actual world. In the final three chapters of Part III, I defend insensitive interventionism against some objections. I consider the objection that causation must be productive, the objection that causes must physically necessitate their effects, and the objection that insensitive interventionism is too permissive. I respond by drawing from the literature on causation by absences and on the relation between causation and fundamental physics. Overall, insensitive interventionism performs as well as standard interventionist accounts. I conclude that insensitive interventionism is a credible model of causation. (shrink)

I think that there is an awful lot wrong with the exclusion problem. So, it seems, does just about everybody else. But of course everyone disagrees about exactly _what_ is wrong with it, and I think there is more to be said about that. So I propose to say a few more words about why the exclusion problem is not really a problem after all—at least, not for the nonreductive physicalist. The genuine _dualist_ is still in trouble. Indeed, one of (...) my main points will be that the nonreductive physicalist is in a rather different position vis à vis the exclusion problem than the dualist is. Properly understanding nonreductive physicalism—and clearly recognizing that it is, after all, a form of _physicalism_—goes a long way toward solving the exclusion problem. (shrink)

Jaegwon Kim (1998a, 2005) claims that his exclusion problem follows a priori for the non-reductive physicalist given her commitment to five apparently inconsistent theses: mental causation, non-identity, supervenience, causal closure and non-overdetermination. For Kim, the combination of these theses entails that mental properties are a priori excluded as causes, forcing the non-reductive physicalist to accept either epiphenomenalism, or some form of reduction. In this thesis, I argue that Kim’s exclusion problem depends on a particular conception of causation, namely sufficient production, (...) and that when causation is understood in interventionist terms, the non-reductive physicalist can avoid the exclusion problem. I argue that Woodward’s (2003, 2008a, 2011a) version of interventionism not only provides an account of mental causation that avoids the exclusion problem, but argue that it also upholds all of the minimal commitments of non-reductive physicalism, thereby providing a successful non-reductive physicalist solution to the exclusion problem. In Chapter 2, I argue that all five theses are minimal commitments of non-reductive physicalism that cannot be rejected in order to avoid the exclusion problem. Chapter 3 identifies the assumptions that I take to underlie the exclusion problem. Chapter 4 introduces and outlines the central features of Woodward’s (2003) interventionism and Chapter 5 argues that Woodward’s interventionist account of mental causation provides a solution to the exclusion problem. I examine two alternative interventionist accounts of mental causation[1] that fail to provide satisfactory solutions to the exclusion problem and conclude that Woodward’s account therefore provides the only satisfactory account of mental causation and solution to the exclusion problem. Chapter 6 addresses some challenges proposed by Michael Baumgartner (2009, 2010) and argues that the interventionist is able to defend her position against these objections and uphold the interventionist solution to the exclusion problem outlined in this thesis. [1. Proposed by List and Menzies (2009) and Campbell (2007, 2008a, 2008b, 2010).]. (shrink)

In this thesis, I argue that physicalism should be understood to be the view that mental properties are realized by physical properties. In doing this, I explore what the realization relation might be. Since realization is the relation that should help us formulate physicalism, I suggest that the theoretical role of realization consists in explaining some of the things that physicalists wish to explain. These are: How are mental properties metaphysically necessitated by physical properties? How are mental properties causally efficacious? (...) A theory of realization should provide resources for answering these questions. Having identified the theoretical role of realization, I discuss several theories of realization, but then focus on the subset view of realization. According to the subset view, a property P realizes a property Q if and only if the causal powers of Q are a proper subset of the causal powers of P. I argue that the realization relation as it is formulated by the subset view is a promising candidate to play the theoretical role that I want realization to play. I then investigate how this theoretical role is occupied. In doing so, I provide a general metaphysical framework that the defenders of the subset view can appeal to. This framework specifies in what ways properties are related to their causal powers. Discussing some problems that the subset view faces, I propose my own version of the subset view. I argue that a property P realizes a property Q if and only if the causal powers of Q are a proper subset of the causal powers of P, and P is more fundamental than Q. Thanks to the requirement that a realized property is less fundamental than its realizers, two things that the original version of the subset view cannot explain are guaranteed: first, fundamental properties are not realized; second, arbitrary conjunctions of properties do not realize their conjuncts. By showing how a theory of realization can help us explain some of the things that physicalists typically wish to explain, I also show that a non-reductive variety of physicalism does not face the problems that it is commonly thought to face. (shrink)

I examine the debate between reductive and non-reductive physicalists, and conclude that if we are to be physicalists, then we should be reductive physicalists. I assess how both reductionists and non-reductionists try to solve the mind-body problem and the problem of mental causation. I focus on the problem of mental causation as it is supposed to be faced by non-reductionism: the so-called overdetermination problem. I argue that the traditional articulation of that problem is significantly flawed, and I show how to (...) articulate it properly: what I call the ‘super-overdetermination problem’. In doing so, I demonstrate that the problem of mental causation faced by non-reductionism is in fact a special case of the mind-body problem, as faced by non-reductionism, and that the former can’t be solved independently of the latter. I then assess the prospects for a particular family of non-reductive views that I call immanentism, and show that they fail to solve the super-overdetermination problem. Finally, I put forward two arguments to support the conclusion that physicalism entails reductionism. Both arguments establish, via distinct reasoning, the proposition that mental property instances are identical to physical property instances; and then each argument employs the inference, which I also defend, that if mental instances are physical instances, then mental properties are physical properties; hence, reductionism follows.

What drives much of the current philosophical interest in the idea of group cognition is its appeal to the manifestation of psychological properties—understood broadly to include states, processes, and dispositions—that are in some important yet elusive sense emergent with respect to the minds of individual group members. Our goal in this paper is to address a set of related, conditional questions: If human mentality is real yet emergent in a modest metaphysical sense only, then: (i) What would it mean for (...) a group to have emergent cognitive states? (ii) Is this even a metaphysically coherent view? (iii) Relative to which notion of emergence do we have reason to believe that certain groups in fact have emergent cognitive states? We shall argue that evidence from a wide variety of social science domains makes it plausible that there are group cognitive states and processes no less metaphysically emergent than human cognitive (and other special science) states and processes.
