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.

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? How can it be that physicalist theories still have a problem (...) explaining something which their physicalism was intended to explain in the first place? If physicalism is meant to be an explanation of mental causation, then why should it still face the problem of mental causation? (shrink)

Empirical evidence, it has often been argued, undermines our commonsense assumptions concerning the efficacy of conscious intentions. One of the most influential advocates of this challenge has been Daniel Wegner, who has presented an impressive amount of evidence in support of a model of "apparent mental causation". According to Wegner, this model provides the best explanation of numerous curious and pathological cases of behavior. Further, it seems that Benjamin Libet's classic experiment on the initiation of action and the (...) empirical evidence concerning the confabulation of reason explanations provide further support for this view. In response, I will propose an alternative model of "real mental causation" that can accommodate the empirical evidence just as well as Wegner's. Further, we will see that there is plenty of evidence in support of the assumption that intentions are causally efficacious. This will provide us with ample reason to endorse the model of real mental causation. (shrink)

The Exclusion Problem for mental causation suggests that there is a tension between the claim that the mental causes physical effects, and the claim that the mental does not overdetermine its physical effects. In response, Karen Bennett puts forward an extra necessary condition for overdetermination : if one candidate cause were to occur but the other were not to occur, the effect would still occur. She thus denies one of the assumptions of EP, the assumption that (...) if an effect has two sufficient causes, it is overdetermined. If sound, her argument does two things: it solves EP, and it shows how to use counterfactuals in order to make the notion of overdetermination precise. However, the argument is not sound. (shrink)

The problem of mental causation is discussed by taking into account some recent developments in the philosophy of science. The problem is viewed from the perspective of the new interventionist theory of causation developed by Woodward. The import of the idea that causal claims involve contrastive classes in mental causation is also discussed. It is argued that mental causation is much less a problem than it has appeared to be.

The problem of mental causation in contemporary philosophy of mind concerns the possibility of holding two different views that are in apparent tension. The first is physicalism, the view that there is nothing more to the world than the physical. The second is that the mental has genuine causal efficacy in a way that does not reduce to pure physical particle-bumping. This article provides a historical background to this question, with focus on Davidson’s anomalous monism and Kim’s (...) causal exclusion problem. Responses to causal exclusion are categorized in terms of six different argumentative strategies. In conclusion, caution is advised regarding the inclination to reduce the mental to the physical and sketch a positive direction for substantively characterizing mental causation by recourse to well-confirmed accounts of causation coupled with empirical research.

Suppose that, for every event, whether mental or physical, there is some physical event causally sufficient for it. Suppose, moreover, that physical reductionism in its various forms fails—that mental properties cannot be reduced to physical properties and mental events cannot be reduced to physical events. In this case, how could there be mental causation? More specifically, how could mental events cause other mental events, physical events, and intentional actions? The primary goal of this (...) paper is to answer this question. (shrink)

Despite Spinoza’s reputation as a thoroughgoing critic of teleology, in recent years a number of scholars have argued convincingly that Spinoza does not wish to eliminate teleological explanations altogether. Recent interpretative debates have focused on a more recalcitrant problem: whether Spinoza has the resources to allow for the causal efficacy of representational content. In this paper I present the problem of mental causation for Spinoza and consider two recent attempts to respond to the problem on Spinoza’s behalf. While (...) these interpretations certainly shed some light on Spinoza’s account of cognitive economy, I argue that both fail to point the way out of the problem because they fail to differentiate between two forms of representation, one of which is causally efficacious, one of which is not. I close by suggesting that there is some reason to believe that Spinoza’s account of mind avoids some of the problems typically associated with mental causation. (shrink)

Book review of 'Tropes: Properties, Objects, and Mental Causation' (2011, OUP). By DOUGLAS EHRING.

Mental causation is a problem and not just a problem for the nonphysicalist. One of the many lessons learned from Jaegwon Kim’s writings in the philosophy of mind is that mental causation is a problem for the nonreductive physicalist as well. A central component of the common sense picture we have of ourselves as persons is that our beliefs and desires causally explain our actions. But the completeness of the “brain sciences” threatens this picture. If all (...) of our actions are causally explained by neurophysiological events occurring in our brains, what causal role is left for our reasons and motives? It would seem that these brain events do all the causal work there is to do, thus robbing the mental of its efficacy altogether or else making it a merely superfluous or redundant causal factor. This essay presents a systematic treatment of this exclusion dilemma from the perspective of a nonreductive physicalist. I argue that both horns of this dilemma can be avoided if we ground mental causation in counterfactual dependence between distinct events and understand the mind-body relation as event realization. Although in the final analysis our actions are overdetermined by their mental and neurophysiological antecedents, this overdetermination is entirely unproblematic. (shrink)

S. C. Gibb holds that some mental events enable physical events to take place by acting as ‘double preventers’ which prevent other mental events from effecting change in the physical domain. She argues that this enables a dualist account of psychophysical interaction consistent with the causal relevance of mental events, their distinctness from physical events, the causal closure of the physical and the exclusion of systematic overdetermination. While accepting the causal powers metaphysic, this paper argues that: Closure (...) is maintained only on the assumption of an implausible pre-ordained harmony between preventing and double-preventing mental events. Distinctness is preserved only at the cost of positing brute unexplained powers of mental and physical events to causally interact with each other. Exclusion is systematically violated in a substantial number of everyday cases. The case for Relevance made by the Double Prevention model is accordingly too weak to sustain a dualist approach to mental causation. (shrink)

The problem of downward causation is that an intuitive response to an intuitive picture leads to counterintuitive results. Suppose a mental event, m1, causes another mental event, m2. Unless the mental and the physical are completely independent, there will be a physical event in your brain or your body or the physical world as a whole that underlies this event. The mental event occurs at least partly in virtue of the physical event’s occurring. And the (...) same goes for m2 [2] and p2. Let’s not worry about what exactly “underlying” or “in virtue of” means here. Here’s the picture. m1 -----> m2 | | p1 -----> p2 The horizontal arrows represent causation, and the vertical lines represent underlying, whatever that may be. There’s some reason to think that the only way m1 can bring about m2 is by bringing about p2. You can’t convince someone of something through mental telepathy. You need to interact with the physical world, perhaps by saying something and so making some noise, or by pointing and getting them to turn their head and see. What goes for the case of two people goes for the case of one person as well. Superstition aside, there is no purely mental energy that floats free of the merely physical workings of the brain. If m1 brings about m2 by bringing about p2, then m1 brings about p2. This is downward causation. But wait. Doesn’t p1 bring about p2? Isn’t that what the bottom arrow represents? Maybe m1 and p1 work together to bring about p2. There are little holes in the physical causal structure that need to be filled by mental events. You don’t need a sweeping metaphysical thesis about the causal closure of the physical to find this implausible. Maybe p2 is overdetermined. (shrink)

The paper argues that tropes cannot be used to solve the mind-body problem, as advocated by David Robb in some paper.

There are numerous theoretical reasons which are usually said to undermine the case for mental causation. But in recent years, Libet‘s experiment on readiness potentials (Libet, Wright, and Gleason 1982; Libet, Gleason, Wright, and Pearl 1983), and a more recent replication by a research team led by John Dylan Haynes (Soon, C.S., Brass, M., Heinze, H.J., and Haynes, J.-D. [2008]) are often singled out because they appear to demonstrate empirically that consciousness is not causally involved in our choices (...) and actions. In this paper, an alternative interpretation of these studies is offered; one which is in accordance both with the empirical evidence and also with the phenomenology of the will, demonstrating that the two opposing views of agency – both the ones that deny the reality of free will and the ones that affirm it – are equally compatible with the outcomes of these two experiments. On this basis, it is shown that the claim that the results on the timing of readiness potential tip the scales in favour of one or the other view cannot be justified - neither from a neurological, nor from a philosophical perspective.

The Problems of Mental Causation. Functionalism in the philosophy of mind identifies mental states with their dispositional connections with other mental states, perceptions and actions. Many theories of the mind have sailed under the Functionalist flag. But what I take to be essential to Functionalism is that mental states are individuated causally: the reality of mental states depends essentially on their causal efficacy.

On the dominant interpretation, Ockham is an externalist about mental content. This reading is founded principally on his theory of intuitive cognition. Intuitive cognition plays a foundational role in Ockham’s account of concept formation and judgment, and Ockham insists that the content of intuitive states is determined by the causal relations such states bear to their objects. The aim of this paper is to challenge the externalist interpretation by situating Ockham’s account of intuitive cognition vis-à-vis his broader account of (...) efficient causation. While there can be no doubt that intuitive states are causally individuated, I argue that, given Ockham’s broader theory of efficient causation (on which causation turns out to be an internal relation), this very fact entails that the content of such states is determined by factors internal (rather than external) to the states themselves. (shrink)

The recent literature on mental causation has not been kind to nonreductive, materialist functionalism (‘functionalism’, hereafter, except where that term is otherwise qualified). The exclusion problem2 has done much of the damage, but the epiphenomenalist threat has taken other forms. Functionalism also faces what I will call the ‘problem of metaphysically necessary effects’ (Block, 1990, pp. 157-60, Antony and Levine, 1997, pp. 91-92, Pereboom, 2002, p. 515, Millikan, 1999, p. 47, Jackson, 1998, pp. 660-61). Functionalist mental properties (...) are individuated partly by their relation to the very effects those properties’ instantiations are thought to cause. Consequently, functionalist causal generalizations would seem to have the following problematical structure: The state of being, among other things, a cause of e (under such-andsuch conditions) causes e (under those conditions).3 The connection asserted lacks the contingency one would expect of a causal generalization. Mental states of the kind in question are, by metaphysical necessity, causes of e; any state that does not cause e is thereby a different kind of state. Yet, a mental state’s being the sort of state it is must play some causal role if functionalism is to account for mental causation.4 In what follows, I first articulate more fully the problem of metaphysically necessary effects. I then criticize three functionalist attempts to solve the problem directly. Given the failure of functionalist efforts to meet the problem head-on, I consider less direct strategies: these involve formulating functionalism or its causal claims in such a way that they appear not to generate the problem of metaphysically necessary effects. I argue against these indirect solutions, in each case concluding either that the problem still arises or that avoiding it requires the adoption of an unorthodox form of functionalism (itself a surprising result). In the final.. (shrink)

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. (shrink)

In this paper I first try to clarify the essential features of tropes and then I use the resulting analysis to cope with the problem of mental causation. As to the first step, I argue that tropes, beside being essentially particular and abstract, are simple, where such a simplicity can be considered either from a phenomenal point of view or from a structural point of view. Once this feature is spelled out, the role tropes may play in solving (...) the problem of mental causation is evaluated. It is argued that no solution based on the determinable/determinate relation is viable without begging the question as regards the individuating conditions of the related properties. Next, it is shown that Robb’s solution, much in the spirit of Davidson’s anomalous monism, entails abandoning the assumption that tropes are essentially simple, a consequence that I find not acceptable. My conclusion is that these entities are of no help in solving the problem of mental causation, and that a universalist approach should be preferred. (shrink)

Most of us have a very firm belief in mental causation; that is, we firmly believe that our own distinctly mental properties are causally efficacious in the production of our behavior. This belief is dominating in contemporary philosophy of mind as a part of the causal explanatory exclusion problem for non-reductive materialists. I do not discuss the exclusion problem; rather, I assess the conception of mental causation that is presupposed in the current debate. I propose (...) that in order to make sense of our firm belief in mental causation we need to operate with a broader conception of it than is normally seen, focusing on common-sense aspects concerning the timing, awareness, control, and tracking of mental causation. However, prominent studies in social psychology and cognitive neuroscience show that mental causation is not as self-evident, robust, and pervasive as our firm belief in it would suggest. There is therefore a tension between the common-sense, broad conception of mental causation and our empirical evidence for mental causation. A full defense of mental causation is not just a matter of securing causal efficacy but also of situating our notion of mental properties in relation to difficult issues concerning awareness, control, and judgment.

As Jaegwon Kim points out in his excellent new book, “reductionism” has become something of a pejorative term in philosophy and related disciplines. But originally (eg, as expressed in Ernest Nagel’s 1961 The Structure of Science) reduction was supposed to be a form of explanation, and one may wonder whether it is reasonable to reject in principle the advances in knowledge which such explanations may offer. Nagel’s own view, illustrated famously by the reduction of thermodynamics to statistical mechanics, was that (...) reduction is a relation between theories: theory A is reduced to theory B by formulating “bridge laws” which link the terminology of the theories, and using them to derive A from B. (An additional reductive claim is that Aphenomena are identical with certain B-phenomena—as when the temperature of a gas is identified with its mean molecular kinetic energy—but this kind of identity claim is, strictly speaking, independent of the claim about theories.) Applied to the case of mental states and brain states, a reduction would provide explanatory relations between psychology and neuroscience, normally supplemented with the claim that mental properties are identical with physical properties in the brain. (shrink)

Many philosophers want to say both that everything is determined by the physical and subject to physical laws and principles, and that certain mental entities cannot be identified with any physical entities. The problem of mental causation is to make these two assumptions compatible with the causal efficacy of the mental. The concern is that this physicalist picture of the world leaves no space for the causal efficacy of anything non-physical. The physical, as it is sometimes (...) said, excludes anything non- physical from doing causal work. (shrink)

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)

This paper presents a puzzle or antinomy about the role of properties in causation. In theories of properties, a distinction is often made between determinable properties, like red, and their determinates, like scarlet (see Armstrong 1978, volume II). Sometimes determinable properties are cited in causal explanations, as when we say that someone stopped at the traffic light because it was red. If we accept that properties can be among the relata of causation, then it can be argued that (...) there are good reasons for allowing that some of these are determinable properties. On the other hand, there are strong arguments in the metaphysics of properties to treat properties as sparse in David Lewis’s (1983) sense. But then it seems that we only need to believe in the most determinate properties: particular shades of colour, specific masses, lengths and so on. And if we also agree with Lewis that sparse properties are ‘the ones relevant to causal powers’ (1983: 13) it seems we must conclude that if properties are relevant to causation at all, then all of these are determinate properties. I call this ‘the antinomy of determinable causation’. On the one hand, we have a good argument for the claim that determinable properties can be causes, if any properties are. I call this the Thesis. But on the other hand, we have a good argument for the claim that only the most determinate properties can be causes, if any properties are. I call this the Antithesis. Clearly, we need to reject either the Thesis or the.. (shrink)

In recent years Jaegwon Kim has offered an argument – the ‘supervenience argument’ – to show that supervenient mental properties, construed as second- order properties distinct from their first-order realizers, do not have causal powers of their own. In response, several philosophers have argued that if Kim’s argument is sound, it generalizes in such a way as to condemn to causal impotency all properties above the level of basic physics. This paper discusses Kim’s supervenience argument in the context of (...) his reply to this so-called ‘generalization argument’. In particular, the paper focuses on the level/order distinction, to which Kim appeals in his reply to the generalization argument, and on the relation between this distinction and two varieties of functionalism, ‘realizer’ vs. ‘role’ functionalism. The author argues that a proper analysis of the notions of levels and orders undermines Kim’s response to the generalization argument, and suggests that Kim’s reductionist strategy for vindicating the causal powers of mental properties is better served if mental properties are construed as first-order properties, as realizer-functionalism recommends.

Many believe that a suitably programmed computer could act for its own goals and experience feelings. I challenge this view and argue that agency, mental causation and qualia are all founded in the unique, homeostatic nature of living matter. The theory was formulated for coherence with the concept of an agent, neuroscientific data and laws of physics. By this method, I infer that a successful action is homeostatic for its agent and can be caused by a feeling - (...) which does not motivate as a force, but as a control signal. From brain research and the locality principle of physics, I surmise that qualia are a fundamental, biological form of energy generated in specialized neurons. Subjectivity is explained as thermodynamically necessary on the supposition that, by converting action potentials to feelings, the neural cells avert damage from the electrochemical pulses. In exchange for this entropic benefit, phenomenal energy is spent as and where it is produced - which precludes the objective observation of qualia. (shrink)

In this paper, I explore anomalous dualism about consciousness, a view that has not previously been explored in any detail. We can classify theories of consciousness along two dimensions: first, a theory might be physicalist or dualist; second, a theory might endorse any of the three following views regarding causal relations between phenomenal properties (properties that characterize states of our consciousness) and physical properties: nomism (the two kinds of property interact through deterministic laws), acausalism (they do not causally interact), and (...) anomalism (they interact but not through deterministic laws). I suggest that a kind of anomalous dualism, nonreductive anomalous panpsychism, promises to offer the best overall answer to two pressing issues for dualist views, the problem of mental causation and the mapping problem (the problem of predicting mind-body associations).

We offer a critical assessment of the “exclusion argument” against free will, which may be summarized by the slogan: “My brain made me do it, therefore I couldn't have been free”. While the exclusion argument has received much attention in debates about mental causation (“could my mental states ever cause my actions?”), it is seldom discussed in relation to free will. However, the argument informally underlies many neuroscientific discussions of free will, especially the claim that advances in (...) neuroscience seriously challenge our belief in free will. We introduce two distinct versions of the argument, discuss several unsuccessful responses to it, and then present our preferred response. This involves showing that a key premise – the “exclusion principle” – is false under what we take to be the most natural account of causation in the context of agency: the difference-making account. We finally revisit the debate about neuroscience and free will. (shrink)

Abstract (for the combined three Parts) This paper presents the simplest known theory of processes involved in a person’s unconscious and conscious achievements such as intending, perceiving, reacting and thinking. The basic principle is that an individual has mental states which possess quantitative causal powers and are susceptible to influences from other mental states. Mental performance discriminates the present level of a situational feature from its level in an individually acquired, multiple featured norm (exemplar, template, standard). The (...) effect on output of a moderate disparity between input and norm is scaled in a universal unit of discrimination (Weber’s fraction), with the norm’s level being zero. When one process converts separate sources of input into an output, their discriminative distances from norm are summated. Distinct processes converging on an output combine their discriminations from norm orthogonally. An output may be influenced by the constructs of other outputs as well as by inputs. Descriptive performance is the influence of one category of input on a verbal output. Reasoning is minimally the effect of one verbal process on another. In deeper mental processing, the influence on a response comes from a response construct modulating a description: this process gives the meaning to an emotion or a motive. Descriptive modulation of stimulation corresponds to a bodily sensation or other conceptualized percept. When an output is explained solely by sources of input, that response to the stimulation may be mediated unconsciously. Development of a person within physical and communal environments embodies such mental causation within material causation and acculturates that mind to social causation. (shrink)

What does it mean to say that mind-body dualism is causally problematic in a way that other mind-body theories, such as the psychophysical type identity theory, are not? After considering and rejecting various proposals, I advance my own, which focuses on what grounds the causal closure of the physical realm. A metametaphysical implication of my proposal is that philosophers working without the notion of grounding in their toolkit are metaphysically impoverished. They cannot do justice to the thought, encountered in every (...) introductory class in the philosophy of mind, that dualism has a special problem accounting for mental causation. (shrink)

Jaegwon Kim’s influential exclusion argument attempts to demonstrate the inconsistency of nonreductive materialism in the philosophy of mind. Kim’s argument begins by showing that the three main theses of nonreductive materialism, plus two additional considerations, lead to a specific and familiar picture of mental causation. The exclusion argument can succeed only if, as Kim claims, this picture is not one of genuine causal overdetermination. Accordingly, one can resist Kim’s conclusion by denying this claim, maintaining instead that the effects (...) of the mental are always causally overdetermined. I call this strategy the ‘ overdetermination challenge’. One of the main aims of this paper is to show that the overdetermination challenge is the most appropriate response to Kim’s exclusion argument, at least in its latest form. I argue that Kim fails to adequately respond to the overdetermination challenge, thus failing to prevent his opponents from reasonably maintaining that the effects of the mental are always causally overdetermined. Interestingly, this discussion reveals a curious dialectical feature of Kim’s latest response to the overdetermination challenge: if it succeeds, then a new, simpler and more compact version of the exclusion argument is available. While I argue against the consequent of this conditional, thereby also rejecting the antecedent, this dialectical feature should be of interest to philosophers on either side of this debate.

Some physicalists (Balog 2012, Howell 2013), and most dualists, endorse the acquaintance response to the Knowledge Argument. This is the claim that Mary gains substantial new knowledge, upon leaving the room, because phenomenal knowledge requires direct acquaintance with phenomenal properties. The acquaintance response is an especially promising way to make sense of the Mary case. I argue that it casts doubt on two claims often made on behalf of physicalism, regarding parsimony and mental causation. I show that those (...) who endorse the acquaintance response face special obstacles to invoking parsimony in an argument for physicalism. And I show how acknowledging the phenomenon of acquaintance can ease the dualist’s problems with mental causation, by dispelling three key objections to epiphenomenalism. The most challenging of these objections is that epiphenomenalism blocks an evolutionary explanation of the so-called “hedonic/utility match”. I propose that pleasures and pains, while themselves epiphenomenal, can nonetheless explain positive and negative associations with stimuli, associations that can contribute to fitness. (shrink)

Although there are several monistic and dualistic approaches to the mind-body problem on the basis of classical or quantum mechanics, thus far no consensus exists about a solution. Recently, the Elementary Process Theory (EPT) has been developed: this corresponds with a fundamentally new disciplinary matrix for the study of physical reality. The purpose of the present research was to investigate the mind-body problem within this newly developed disciplinary matrix. The main finding is that the idea of a duality of body (...) and mind has to be rejected as an incomplete representation of reality: in the universe of the EPT, man hás to be a trinity of body, spirit and soul, where ‘body’, ‘spirit’ and ‘soul’ are names for distinct physical things. The mind is then a mere idea that arises from (self-)experience, but without onto-logical connotation. In addition a mechanism for mental causation, which implies a principle of choice, is rigorously formulated. The main conclusion is that a fundamentally new physicalist approach to the mind-body problem, according to which man has a free will, has been formulated strictly within the language of the EPT. Further physical research is then required to describe how the interaction between body, spirit and soul is to be understood in terms of fundamental interactions. In addition, further philosophical-theological research has to establish whether the presently discussed trinity and the trinities of body, spirit and soul mentioned in the Bible and the Vedic texts are one and the same thing.

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 statesshare the causal powers of their physical counterparts. In this paper, I present a variety of counterarguments to causal inheritance and conclude that the conditions 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. (shrink)

I agree with Nachev and Hacker’s general approach. However, their criticism of claims of covert automaticity can be strengthened. I first say a few words on what voluntary action involves and on the consequent limited relevance of brain research for the determination of voluntariness. I then turn to Nachev and Hacker’s discussion of possible covert automaticity and show why the case for it is weaker than they allow.

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.

Jaegwon Kim’s supervenience/exclusion argument attempts to show that non-reductive physicalism is incompatible with mental causation. This influential argument can be seen as relying on the following principle, which I call “the piggyback principle”: If, with respect to an effect, E, an instance of a supervenient property, A, has no causal powers over and above, or in addition to, those had by its supervenience base, B, then the instance of A does not cause E (unless A is identical with (...) B). In their “Epiphenomenalism: The Dos and the Don’ts,” Larry Shapiro and Elliott Sober employ a novel empirical approach to challenge the piggyback principle. Their empirical approach pulls from the experiments of August Weismann regarding the inheritance of acquired characteristics. Through an examination of Weismann’s experiments, Shapiro and Sober extract lessons in reasoning about the epiphenomenalism of a property. And according to these empirically drawn lessons, the piggyback principle is a don’t. My primary aim in this paper is to defend the piggyback principle against Shapiro and Sober’s empirical approach.

Functionalists think an event's causes and effects, its 'causal role', determines whether it is a mental state and, if so, which kind. Functionalists see this causal role principle as supporting their orthodox materialism, their commitment to the neuroscientist's ontology. I examine and refute the functionalist's causal principle and the orthodox materialism that attends that principle.

In her landmark book, Language, Thought, and Other Biological Categories (Millikan1984),1 Ruth Garrett Millikan utilizes the idea of a biological function to solve philosophical problems associated with the phenomena of language, thought, and meaning. Language and thought are activities of biological organisms, according to Millikan, and we should treat them as such when trying to answer related philosophical questions. Of special interest is Millikan’s treatment of intentionality. Here Millikan employs the notion of a biological function to explain what it is (...) for one thing in nature, a bee dance (43), for example, to be about another, in this case, the location of a nectar source. My concern in this paper is to understand whether Millikan’s account of intentionality adequately explains how humans achieve reference, in language or thought, to individuals and groups in their environment. In bringing her theory of intentional content to bear on human activities, Millikan focuses largely on natural language. Thus, in what follows, I begin by laying out the biology-based principles that underlie Millikan’s theory of content, then proceed with an explanation of how the theory is to apply to natural language. As it appears, Millikan’s account of how content is determined for natural language terms and sentences rests on the determinacy of intentional content at the psychological level. This leads me to take a careful look at what Millikan says about the content of mental representations, in hopes of finding a sufficient basis there for the application of Millikan’s theory of content to natural language. Ultimately, I conclude that Millikan’s theory faces a problem of vacuity. If we approach the theory as a theory of intentional content, intended to explain the nature of reference, the theory is lacking in an extremely important respect: Millikan explains how it could be one of the biological functions of a mental or natural language term to refer, without telling us precisely what in the natural order constitutes the reference relation..

A popular response to the Exclusion Argument for physicalism maintains that mental events depend on their physical bases in such a way that the causation of a physical effect by a mental event and its physical base needn’t generate any problematic form of causal overdetermination, even if mental events are numerically distinct from and irreducible to their physical bases. This paper presents and defends a form of dualism that implements this response by using a dispositional essentialist (...) view of properties to argue that the psychophysical laws linking mental events to their physical bases are metaphysically necessary. I show the advantages of such a position over an alternative form of dualism that merely places more “modal weight” on psychophysical laws than on physical laws. The position is then defended against the objection that it is inconsistent with dualism. Lastly, some suggestions are made as to how dualists might clarify the contribution that mental causes make to their physical effects. (shrink)

In order to defend mental explanations dualists may appeal to dispositions (powers). By accepting a powers theory of causation, a dualist can more plausibly defend mental explanations that are given independently of physical explanations. Accepting a power-based theory still comes with a price. Absences and double preventers are not causes in a powers theory, and solutions based on them can only defend their explanatory relevance in mental explanations. There is still a chance that such mental (...) explanations can be causal explanations, though they do not refer to real causes. (shrink)

In ‘The Mental Causation Debate’ (1995), I pointed out the parallel between the premises in some traditional arguments for physicalism and the assumptions which give rise to the problem of mental causation. I argued that the dominant contemporary version of physicalism finds mental causation problematic because it accepts the main premises of the traditional arguments, but rejects their conclusion: the identification of mental with physical causes. Moreover, the orthodox way of responding to this (...) problem (which I call the ‘constitution view’) implicitly rejects an assumption hidden in the original argument for physicalism: the assumption that mental and physical causation are the same kind of relation (‘homogeneity’). The conclusion of my paper was that if you reject homogeneity, then there is no obvious need for an account of the relation between mental and physical properties. (shrink)

The thesis develops solutions to two main problems for mental realism. Mental realism is the theory that mental properties, events, and objects exist, with their own set of characters and causal powers. The first problem comes from the philosophy of science, where Psillos proposes a notion of scientific realism that contradicts mental realism, and consequently, if one is to be a scientific realist in the way Psillos recommends, one must reject mental realism. I propose adaptations (...) to the conception of scientific realism to make it compatible with mental realism. In the process, the thesis defends computational cognitive science from a compelling argument Searle can be seen to endorse but has not put forth in an organized logical manner. A new conception of scientific realism emerges out of this inquiry, integrating the mental into the rest of nature. The second problem for mental realism arises out of non-reductive physicalism- the view that higher-level properties, and in particular mental properties, are irreducible, physically realized, and that physical properties are sufficient non-overdetermining causes of any effect. Kim’s Problem of Causal Exclusion aims to show that the mental, if unreduced, does no causal work. Consequently, given that we should not believe in the existence of properties that do not participate in causation, we would be forced to drop mental realism. A solution is needed. The thesis examines various positions relevant to the debate. Several doctrines of physicalism are explored, rejected, and one is proposed; the thesis shows the way in which Kim’s reductionist position has been constantly inconsistent throughout the years of debate; the thesis argues that trope theory does not compete with a universalist conception of properties to provide a solution; and shows weakness in the Macdonald’s non-reductive monist position and Pereboom’s constitutional coincidence account of mental causation. The thesis suggests that either the premises of Kim’s argument are consistent, and consequently his reductio is logically invalid, or at least one of the premises is false, and therefore the argument is not sound. Consequently, the Problem of Causal Exclusion that Kim claims emerges out of non-reductive physicalism does not force us to reject mental realism. Mental realism lives on. (shrink)

It is often argued that higher-level special-science properties cannot be causally efficacious since the lower-level physical properties on which they supervene are doing all the causal work. This claim is usually derived from an exclusion principle stating that if a higherlevel property F supervenes on a physical property F* that is causally sufficient for a property G, then F cannot cause G. We employ an account of causation as differencemaking to show that the truth or falsity of this principle (...) is a contingent matter and derive necessary and sufficient conditions under which a version of it holds. We argue that one important instance of the principle, far from undermining non-reductive physicalism, actually supports the causal autonomy of certain higher-level properties. (shrink)

If we reject physicalism, for the reasons given in my 2011 book ‘Panpsychism,’ we can arrive at a variant of idealism that accepts the concrete existence of all entities discoverable by science, but argues that these are nothing over and above centres of experience that can perceive one another and act on their percepts. In this metaphysical system, all physical properties and laws reduce without remainder to mental dittos – length is used in this paper as an example. Adopting (...) this position resolves many difficulties in the philosophy of mind, including the problems of: the explanatory gap, mental causation, perception, qualia and zombies. (shrink)

The thesis that follows proffers a solution to the mind-matter problem, the problem as to how mind and matter relate. The proposed solution herein is a variant of panpsychism – the theory that all (pan) has minds (psyche) – that we name pansentient monism. By defining the suffix 'psyche' of panpsychism, i.e. by analysing what 'mind' is (Chapter 1), we thereby initiate the effacement of the distinction between mind and matter, and thus advance a monism. We thereafter critically examine the (...) prevalent view, antithetical to a pansentient monism, that mind is not identical to matter but emergent therefrom (Chapter 2). This anti-emergentist critique acts also as a fortification of the Genetic Argument for panpsychism: if mind is not emergent (nor distinct) from matter, mind must always have existed with matter. But what is 'matter'? Chapter 3 investigates what we understand by 'matter', or 'the physical', and exposes it as a highly deficient concept and percept that in concreto points to its identity with that denoted by 'mind'. This also acts as a fortification of the Abstraction Argument for panpsychism, employing a new taxonomy of physicalism and a new taxonomy of the varieties of abstraction. Thus do we reach a monism that is a parsimonious psycho-physical identity theory. But here we face what can be called The Identity Problem for Panpsychism: if our panpsychism is a psycho-physical identity theory, how can it respond to the powerful objections that beset the identity theory of the twentieth century? In Chapter 4 it will be argued that, like emergentism, this psycho-neural identity theory presupposed a deficient concept of 'matter', down to which mind was reduced away, let alone identified. But to identify down phenomena to what is actually an abstraction is to commit failure of explanation. When the theory is amended accordingly, we move from a psycho-neural identity theory to a genuine psycho-physical identity theory that as such can overcome the aforementioned identity problem. Furthermore, as Chapter 5 clarifies, our pansentient monism has, in addition to parsimony, the explanatory power to resolve the problem of mental causation that afflicts both the reductive physicalism of psycho-neural identity theory and the non-reductive physicalism of emergentism, by genuinely identifying physical and mental causation. Jaegwon Kim considers the place of consciousness in a physical world and the nature of mental causation to be the two key components of the mind-matter problem. Through the critical analysis of our prosaic understanding of mind and matter in this thesis, which incorporates the thought of both classical and contemporary thinkers through a novel fusion, it is hoped that both components are addressed and redressed. That is to say that I present this pansentient monism as a plausible, parsimonious, explanatory, and thus, I think, powerful position towards this ever-perplexing mind-matter mystery. -/- [This thesis was passed in January 2019 with viva examination from Galen Strawson and Joel Krueger.

The principle of energy conservation is widely taken to be a se- rious difficulty for interactionist dualism (whether property or sub- stance). Interactionists often have therefore tried to make it satisfy energy conservation. This paper examines several such attempts, especially including E. J. Lowe’s varying constants proposal, show- ing how they all miss their goal due to lack of engagement with the physico-mathematical roots of energy conservation physics: the first Noether theorem (that symmetries imply conservation laws), its converse (that conservation (...) laws imply symmetries), and the locality of continuum/field physics. Thus the “conditionality re- sponse”, which sees conservation as (bi)conditional upon symme- tries and simply accepts energy non-conservation as an aspect of interactionist dualism, is seen to be, perhaps surprisingly, the one most in accord with contemporary physics (apart from quantum mechanics) by not conflicting with mathematical theorems basic to physics. A decent objection to interactionism should be a posteri- ori, based on empirically studying the brain. (shrink)

Western philosophy and science have a strongly dualistic tradition regarding the mental and physical aspects of reality, which makes it difficult to understand their possible causal relations. In recent debates in cognitive neuroscience it has been common to claim on the basis of neural experiments that conscious experiences are causally inefficacious. At the same time there is much evidence that consciousness does play an important role in guiding behavior. The author explores whether a new way of understanding the causal (...) role of mental states and consciousness could be provided by the ontological interpretation of the quantum theory (Bohm and Hiley, Phys. Rep. 144:323–348, 1987; Bohm and Hiley, The undivided universe: An ontological interpretation of quantum theory. Routledge: London, 1993). This interpretation radically changes our notion of matter by suggesting that a new type of active information plays a causal role at the quantum level of reality. The author thus considers to what extent the alleged causal powers of consciousness involve information, and then moves on to consider whether information in (conscious) mental states can be connected to the information at the level of quantum physics. In this way he sketches how quantum theory might help to throw light upon one of the grand challenges facing the social sciences and the humanities, namely the question of whether consciousness plays any genuine causal role in the physical world.
