Substance dualism is widely rejected by philosophers of mind, but many continue to accept some form of property dualism. The assumption here is that one can consistently believe that (1) mental properties are not physical properties, while denying that (2) mental particulars are not physical particulars. But is this assumption true? This paper considers several analyses of what makes something a physical particular (as opposed to a non-physical particular), and it is argued that on any plausible analysis, (...) accepting (1) requires accepting (2) as well.

Property dualism is enjoying a slight resurgence in popularity, these days; substance dualism, not so much. But it is not as easy as one might think to be a property dualist and a substance materialist. The reasons for being a property dualist support the idea that some phenomenal properties (or qualia) are as fundamental as the most basic physical properties; but what material objects could be the bearers of the qualia? If even some qualia require (...) an adverbial construal (if they are modifications of the thing that is conscious because of them, not properties of something else to which the subject of consciousness is related), then the property dualist can be driven to speculative forms of materialism none of which, at this point, looks more likely to be true than the more modest versions of emergent dualism defended by contemporary substance dualists.

I argue that property dualists cannot hold that minds are physical substances. The focus of my discussion is a property dualism that takes qualia to be sui generis features of reality.

It is widely thought that mind–body substance dualism is implausible at best, though mere “property” dualism is defensible and even flourishing. This paper argues that substance dualism is no less plausible than property dualism and even has two advantages over it.

Substance dualism is the view that there are two fundamentally different kinds of substances: physical and mental. By contrast, according to property dualism there is only one kind of substance (physical) but two fundamentally different kinds of properties: physical and mental. Property nominalism is the view that there are neither repeatable nor non-repeatable fundamentally predicable entities (i.e. neither universals nor tropes) and that things being a certain way or being related in a certain way must ultimately (...) be accounted for in terms of concrete particulars. In this paper, we consider a number of different kinds of property nominalism and argue that none of them sits well with property dualism. We pay special attention to the question of what it could mean for a property to count as mental given different nominalistic accounts of properties. Our conclusion is that property nominalism and property dualism are not a stable match. This is surprising, since property dualism has usually been understood as a thesis that is neutral about the nature of fundamental ontological categories and the relation between them. (shrink)

This chapter defends the property dualism argument. The term “semantic premise” mentioned is used to refers to an assumption identified by Brian Loar that antiphysicalist arguments, such as the property dualism argument, tacitly assume that a statement of property identity that links conceptually independent concepts is true only if at least one concept picks out the property it refers to by connoting a contingent property of that property. It is argued that, the (...) property that does the work in explaining the possibility of a posteriori identities need not be a first-order property of the referent in question. On his view, the property dualism argument requires only a weaker semantic premise, which allows that the property in question be a higher order property. A refined version of the property dualism argument is formulated, which uses the weaker premise, and defends the argument against various objections. (shrink)

I attempt to rebut Dean Zimmerman's novel argument (2010), which he presents in support of substance dualism, for the conclusion that, in spite of its popularity, the combination of property dualism with substance materialism represents a precarious position in the philosophy of mind. I take issue with Zimmerman's contention that the vagueness of ‘garden variety’ material objects such as brains or bodies makes them unsuitable candidates for the possession of phenomenal properties. I also argue that the ‘speculative (...) materialism’ that is available to a substance materialist property dualist who abandons the identification of persons with such garden variety objects is significantly more attractive than Zimmerman allows. Although I do not attempt to refute its substance dualist rival, I conclude that the combination of property dualism with substance materialism can withstand Zimmerman's objections. (shrink)

This paper examines some consequences of the (quasi-)epiphenomenalism implied by a property dualistic view of phenomenal consciousness. The focus is upon the variation of phenomenal content over time. A thought-experiment is constructed to support two claims. The weaker claim exhibits an incompatibility which arises in certain logically possible situations between a conscious subject’s epistemic norms and the requirement that one be aware of one’s conscious experience. This could be interpreted as providing some epistemic grounds for the postulation of bridging (...) laws between the physical/functional and phenomenal domains. The stronger claim has it that the ontology of property dualism is not properly able to account for the certainty I have of being phenomenally conscious. The problem is viewed as resulting from the neglect of the intensional context involved in a proper representation of the argument for property dualism. It is argued that only a transcendental move can do justice to this certainty I have. (shrink)

Many contemporary philosophers of mind are concerned to defend a thesis called a posteriori physicalism. This thesis has two parts, one metaphysical, and the other epistemological. The metaphysical part of the thesis—the physicalist part—is the claim that the psychological nature of the actual world is wholly physical. The epistemological part of the thesis—the a posteriori part—is the claim that no a priori connection holds between psychological nature and physical nature. Despite its attractiveness, however, a familiar argument alleges that a posteriori (...) physicalism cannot be true. This argument is sometimes called the Property Dualism Argument Against Physicalism. In this paper, I consider Stephen White’s version of the Property Dualism Argument and argue that it fails. I distinguish two ways in which the argument’s crucial notion might be understood, and I argue that on neither way of understanding it is the Property Dualism Argument compelling. (shrink)

This paper is divided into two main sections. The first articulates what I believe Strawson's position to be. I contrast Strawson's usage of 'physicalism' with the mainstream use. I then explain why I think that Strawson's position is one of property dualism and substance monism. In doing this, I outline his view and Locke's view on the nature of substance. I argue that they are similar in many respects and thus it is no surprise that Strawson actually holds (...) a view on the mind much like one plausible interpretation of Locke's position. Strawson's use of terminology cloaks this fact and he does not himself explicitly recognize it in his paper. In the second section, I outline some of Strawson's assumptions that he uses in arguing for his position. I comment on the plausibility of his position concerning the relation of the mind to the body compared with mainstream physicalism and various forms of dualism. Before embarking on the two main sections, in the remainder of this introduction, I very briefly sketch Strawson's view. (shrink)

In recent years there has been a resurgence of interest in property dualism—the view that some mental properties are neither identical with, nor strongly supervenient on, physical properties. One of the principal objections to this view is that, according to natural science, the physical world is a causally closed system. So if mental properties are really distinct from physical properties, then it would seem that mental properties never really cause anything that happens in the physical world. Thus, (...) class='Hi'>dualism threatens to lead inexorably to epiphenomenalism. In this paper, I will argue that the only way for a property dualist to avoid epiphenomenalism is to deny that the human body is strictly identical with the sum of its microphysical parts. I will go on to argue that the only way to sustain such anti-reductionism about the human body is to embrace some sort of substance-hylomorphism. (shrink)

In this paper I develop an argument against a type of Non-Analytic Normative Naturalism. This argument, the Normative Property Dualism Argument, suggests that, if Non-Analytic Normative Naturalists posit that normative properties are identical to natural properties and that such identities are a posteriori, they will be forced to posit that these properties which are both normative and natural have higher-order normative properties of their own.

Several philosophers have argued that property dualism and substance materialism are incompatible positions. Recently, Susan Schneider has provided a novel version of such an argument, claiming that the incompatibility will be evident once we examine some underlying metaphysical issues. She purports to show that on any account of substance and property-possession, substance materialism and property dualism turn out incompatible. In this paper, I argue that Schneider’s case for incompatibility between these two positions fails. After briefly (...) laying out her case for incompatibility, I present an account of substance—one that relies on a relational ontology—that makes the combination of substance materialism and property dualism unproblematic. Then I show that even under the theories of substance that Schneider considers—those that rely on a constituent ontology—there still is no incompatibility problem. (shrink)

Searle suggests biological naturalism as a solution to the mind-brain problem that escapes traditional terminology with its seductive pull towards either dualism or materialism. We reconstruct Searle's argument and demonstrate that it needs additional support to represent a position truly located between dualism and materialism. The aim of our paper is to provide such an additional argument. We introduce the concept of "autoepistemic limitation" that describes our principal inability to directly experience our own brain as a brain from (...) the first-person perspective. The neglect of the autoepistemic limitation leads to inferences from epistemic properties to ontological features - we call this "epistemic-ontological inference." Searle attempts to avoid such epistemic-ontological inference but does not provide a sufficient argument. Once the autoepistemic limitation is considered, epistemic-ontological inference can be avoided. As a consequence, one can escape traditional terminology with its seductive pull towards either dualism or materialism. (shrink)

My overall aim here is to intersect two issues central to Max Velmans' wide-ranging paper. The first concerns one of the most vexing problems in consciousness research — how best to approach the terms 'mental' and 'physical'. The second looks at the phenomenology of volition, and the degree to which information presumably necessary for making voluntary conscious decisions is, or is not, present in consciousness. Velmans offers three general reasons to motivate his position: the physical world is 'causally closed' to (...) the influence of consciousness; consciousness does not contain the information necessary for making volitional decisions; conscious feelings of volition occur before the acts they supposedly cause. It seems to me that none of this holds up well under scrutiny. I will concentrate on the first two reasons, since I think they involve more basic and widespread aspects of consciousness research.

I have argued in a number of writings[1] that the philosophical part (though not the neurobiological part) of the traditional mind-body problem has a fairly simple and obvious solution: All of our mental phenomena are caused by lower level neuronal processes in the brain and are themselves realized in the brain as higher level, or system, features. The form of causation is.

We argue that the so-called "property-dualist" theory of consciousness is consistent both with current neurobiological data and with modern theories of physics. The hypothesis that phenomenal properties are global properties that are irreducible to microphysical properties, whose role is to integrate information across large portions of the brain, is consistent with current neurobiological knowledge. These properties can exercise their integration function through action on microscopic structures in the neuron without violating the laws of quantum mechanics. Although we offer no (...) positive argument for the existence of irreducibly global properties, the conclusion is that this view is a scientifically respectable hypothesis that deserves to be investigated.

In Max Black’s Objection to Mind–Body Identity, Ned Block seeks to offer a definitive treatment of property dualism arguments that exploit modes of presentation. I will argue that Block’s central response to property dualism is confused. The property dualist can happily grant that mental modes of presentation have a hidden physical nature. What matters for the property dualist is not the hidden physical side of the property, but the apparent mental side. Once that (...) ‘thin’ side is granted, the property dualist has won. I conclude that although Block is wrong to think that the property dualist must argue for so-called thin mental properties, Block, and the physicalist, are able to resist property dualism. But any attempt to bolster this resistance and do more than dogmatically assert the crucial identity runs a serious risk of undermining the physicalism it is meant to save. (shrink)

This paper sketches and motivates a metaphysics of mind that is both substance dualist and, to a large extent, property reductive. Call it “property reductive emergent dualism”. Section “Emergent Dualism” gives the broad outlines of the view. Sections “Problems of Mental Causation” and “Theoretical Virtues” argue that it can claim several advantages over non-reductive physicalist theories of mind. Section “Problems of Mental Causation” considers metaphysical challenges to mental causation in detail. Section “Theoretical Virtues” considers overall theoretical (...) virtues: ontological and ideological economy, unification with physical sciences, the promise of explanatory gain. On these grounds, I propose that the view coupling substance dualism with property reductivism deserves further philosophical attention. (shrink)

The attribution of perceptually based aesthetic properties to a garden should be indexed to whether that attribution is (1) to the ever-changing dynamic garden or (2) to some phenomenal capture of the garden in one’s experience, frozen like a photograph. Perceptually based aesthetic properties are used to identify objects, to compare them to others, to evaluate them, and to describe them as we seek to interpret or find meaning in them. This set of activities requires aesthetic properties that do not (...) change, or at least not much, if any degree of normativity is to be maintained. But those aesthetic properties that are derived from our immediate sensations of a garden only describe a garden at a certain time, under certain conditions, in certain states—all of which change constantly. Both descriptions are useful, and perhaps necessary, for appreciating gardens. (shrink)

To the extent that dualism is even taken to be a serious option in contemporary discussions of personal identity and the philosophy of mind, it is almost exclusively either Cartesian dualism or property dualism that is considered. The more traditional dualism defended by Aristotelians and Thomists, what I call hylemorphic dualism, has only received scattered attention. In this essay I set out the main lines of the hylemorphic dualist position, with particular reference to personal (...) identity. First I argue that overemphasis of the problem of consciousness has had an unhealthy effect on recent debate, claiming instead that we should emphasize the concept of form. Then I bring in the concept of identity by means of the notion of substantial form. I continue by analyzing the relation between form and matter, defending the traditional theses of prime matter and of the unicity of substantial form. I then argue for the immateriality of the substantial form of the human person, viz. the soul, from an account of the human intellect. From this follows the soul's essential independence of matter. Finally, although the soul is the immaterial bearer of personal identity, that identity is still the identity of an essentially embodied being. I explain how these ideas are to be reconciled. Footnotesa I am grateful to Stephen Braude, John Cottingham, John Haldane, David Jehle, Joel Katzav, Eduardo Ortiz, and Fred Sommers for helpful comments and discussion of a draft of this essay. I would also like to thank Ellen Paul, whose suggestions have helped greatly to improve the essay's style and content. (shrink)

This chapter draws an analogy between substance dualism (SD) and one kind of creationism. Some substance dualists appear to believe that SD is preferable to physicalism because only the former can account for the existence of morality. Some dualists are attracted to emergence, although it is unclear that it is a form of SD; indeed, it is not clear that it is a form of dualism at all, and if it is it would seem to be a form (...) of property dualism. The chapter discusses SD's relationship to three key elements of religious doctrine and the idea of emergence. It describes most serious arguments for physicalism and consequently against SD. According to SD, mind and brain are radically different substances, the former nonphysical, the latter physical. Advocates of occasionalist SD claim that God appropriately correlates mental and physical events occasion by occasion. (shrink)

Arguments for property dualism offer a strong challenge to materialist views, but even if they are regarded as successful, a large task remains, namely, to develop a positive account of the place of non-physical properties in the world -- one that holds some promise of eventual satisfaction regarding the hard problem. After noting some difficulties in current approaches to this task, this paper outlines one possible line of development for a dualistic view. Like all other suggestions for routes (...) to progress in this area, this one is speculative. However, the empirical findings that would support this line of development lie within current epistemic possibility. Moreover, the conceptual changes that would be required are intelligible from our present vantage point, and have parallels in views that are accepted in science and by non-dualist philosophers.

The article discusses the relationship between John Searle’s doctrine of naturalism and various forms of materialism and dualism. It is argued that despite Searle’s protestations, his doctrine is not substantially differ- ent from the epiphenomenalistic property dualism, except for the admis- sion, in his later works, of the existence of an irreducible non-Humean self. In particular, his recognition that consciousness is unique in having an irreducible first-person ontology makes his disavowal of property du- alism purely verbalistic. (...) As for epiphenomenalism, Searle’s explanation of how consciousness can be efficacious without violating the causal clo- sure of the physical, by analogy with the causal efficacy of the higher level properties of physical objects that are supervenient on the microphysical, confuses causality and constitution (causal and constitutive superve- nience). It is also argued that Searle’s recognition of the existence of an irreducible non-Humean self that is responsible for decision-making sits badly both with his (property dualistic) view that conscious mental states are irreducibly first-personal states of the brain (rather than of the self) and with his (epiphenomenalistic) view that consciousness has no causal power in addition to that of the underlying neurobiology.

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)

This chapter explains that most of the standard objections to substance dualism (SD) count as effectively against property dualism (PD), and that PD is hardly more plausible, or less implausible, than SD. Dualism competes, not with neuroscience (a science), but with materialism, an opposing philosophical theory. The chapter shows that although Cartesian dualism faces some serious objections, that does not distinguish it from other philosophical theories, and the objections are not an order of magnitude worse (...) than those confronting materialism in particular. There remain the implausibilities required by the Cartesian view; but bare claim of implausibility is not argument. The dialectical upshot is that, on points, and going just by actual arguments as opposed to appeals to decency and what good guys believe, materialism is not significantly better supported than dualism.

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)

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).

Dualism is the view that mental phenomena are, in some respect, nonphysical. The best-known version is due to Descartes, and holds that the mind is a nonphysical substance. Descartes argued that, because minds have no spatial properties and physical reality is essentially extended in space, minds are wholly nonphysical. Every human being is accordingly a composite of two objects: a physical body, and a nonphysical object that is that human being's mind. On a weaker version of dualism, which (...) contemporary thinkers find more acceptable, human beings are physical substances but have mental properties, and those properties aren't physical. This view is known as property dualism, or the dual-aspect theory. (shrink)

A large, diverse sample of adults was interviewed about their conception of the ontological and functional properties of the mind as compared to the soul. The existence of the mind was generally tied to the human lifecycle of conception, birth, growth and death, and was primarily associated with cognitive as opposed to spiritual functions. In contrast, the existence of the soul was less systematically tied to the lifecycle and frequently associated with spiritual as opposed to cognitive functions. Participants were also (...) asked about three ethical issues: stem cell research, life support for patients in a persistent vegetative state and cloning. As expected, participants' beliefs about the ontology and function of the soul were linked to their judgments about these ethical issues whereas their beliefs about the mind were unrelated. Overall, the findings show that many adults do not espouse a simple body-mind dualism, and any tendency toward such dualism is unlikely to explain their beliefs in an afterlife. Instead, afterlife beliefs appear to be associated with the idea of an immaterial essence, potentially dissociable from the biology of life and death. (shrink)

All organised bodies are composed of parts, similar to those composing inorganic nature, and which have even themselves existed in an inorganic state; but the phenomena of life, which result from the juxtaposition of those parts in a certain manner, bear no analogy to any of the effects which would be produced by the action of the component substances considered as mere physical agents. To whatever degree we might imagine our knowledge of the properties of the several ingredients of a (...) living body to be extended and perfected, it is certain that no mere summing up of the separate actions of those elements will ever amount to the action of the living body itself.

This paper is to spell out a version of perception dualism, whose ontological description of the mind-body relation is stronger than property dualism but weaker than substance dualism, that is, to define mental events as perceptions from an internal point of view and physical events as perceptions from an external point of view, then, the author set out to tackle some long-persisting ontological issues in philosophy of mind, such as the psycho-physical interaction, the criterion of mind, (...) the clash between free will and natural necessity, Benjamin Libet’s Experiment. It also recovers some of the observations and conclusions achieved byCartesian internalism and Leibniz’s parallelism. Since perception is the most essential feature of mind, while defining mental and physical events in terms of perception, the author also develops a philosophical theory of perception. (shrink)

We examine Sophie Gibb’s emergent property-dualist theory of mental causation as double-prevention. Her account builds on a commitment to a version of causal realism based on a powers metaphysic. We consider three objections to her account. We show, by drawing out the implications of the ontological commitments of Gibb’s theory of mental causation, that the first two objections fail. But, we argue, owing to worries about cases where there is no double-preventive role to be played by mental properties, her (...) account, which solely affords mental properties a double-preventive role, is incomplete and vulnerable to a causal exclusion objection. We propose a friendly modification to her theory of mental causation that is consistent with her theory’s ontological commitments. Specifically, we sketch an account on which mental properties have a more pronounced causal-structuring role that is not exhausted by the role Gibb assigns them as double-preventers. The result is a novel emergentist theory of mental causation. (shrink)
