This paper presents a moral argument in support of the view that the mind is a nonphysical object. It is intuitively obvious that we, the bearers of conscious experiences, have an inherent value that is not reducible to the value of our conscious experiences. It remains intuitively obvious that we have inherent value even when we represent ourselves to have no physical bodies whatsoever. Given certain assumptions about morality and moral intuitions, this implies that the bearers of conscious experiences—the objects (...) possessing inherent value—are not physical objects. This moral evidence is corroborated by introspective evidence. (shrink)

Descartes maintained substance dualism, the thesis that no substance has both mental and material properties. His main argument for this thesis, the so-called separability argument from the Sixth Meditation (AT VII: 78) has long puzzled readers. In this paper I argue that Descartes’ independence conception of substance (which Descartes presents in article 51 of the Principles) is crucial for the success of the separability argument and that Descartes used this conception of substance to defend his (...) argument for substance dualism from an important objection.

Many contemporary philosophers of mind disagree with substance dualism, saying that despite the failure of physical theories of mind, substance dualism cannot be advocated, because it faces more serious problems than physical theories, lacking compatibility with philosophical arguments and scientific evidence. Regardless of the validity of the arguments in support of substance dualism, it is demonstrated in this article that this theory is coherent, with no philosophical or scientific problems. The main arguments of opponents (...) of substance dualism are explained and criticized in this respect. Based on this, it becomes clear that the interaction of soul and body has a reasonable philosophical explanation, the problem of the pairing of soul and body, although it may not have a scientific explanation, it has a philosophical and theological solution, the principle of the physical causal closure lacks conclusive reasons and cannot reject the existence of the soul, the existence of the soul does not contradict the theory of evolution, the dependence of the soul on the brain is compatible with its independence, and finally, the principle of simplicity does not make any problem for accepting the substance dualism.

This article aims to review the standard objections to dualism and to argue that will either fail to convince someone committed to dualism or are flawed on independent grounds. I begin by presenting the taxonomy of metaphysical positions on concrete particulars as they relate to the dispute between materialists and dualists, and in particular substance dualism is defined. In the first section, several kinds of substance dualism are distinguished and the relevant varieties of this (...) kind of dualism are selected. The remaining sections are analyses of the standard objections to substance dualism : It is uninformative, has troubles accounting for soul individuation, causal pairing and interaction, violates laws of physics, is made implausible by the development of neuroscience and it postulates entities beyond necessity. I conclude that none of these objections is successful. (shrink)

Unger has recently argued that if you are the only thinking and experiencing subject in your chair, then you are not a material object. This leads Unger to endorse a version of Substance Dualism according to which we are immaterial souls. This paper argues that this is an overreaction. We argue that the specifically Dualist elements of Unger’s view play no role in his response to the problem; only the view’s structure is required, and that is available to (...) Unger’s opponents. We outline one such non-Dualist view, suggest how to resolve the dispute, respond to some objections, and argue that ours is but one of many views that survive Unger’s challenge. All these views are incompatible with microphysicalism. So Unger’s discussion does contain an insight: if you are the only conscious subject in your chair, then microphsyicalism is false. Unger’s mistake was to infer Substance Dualism from this; for microphysicalism is not the only alternative to Dualism. (shrink)

In this paper, I will argue that Locke is a substance dualist in the general sense, in that he holds that there are, independent of our classificatory schema, two distinct kinds of substances: wholly material ones and wholly immaterial ones. On Locke’s view, the difference between the two lies in whether they are solid or not, thereby differentiating him from Descartes. My way of establishing Locke as a general substance dualist is to be as minimally committal as possible (...) at the outset, especially with respect to the classic debates on Locke’s positions in this domain, including those concerning substrata, real essences, and the like. Nonetheless, I show that minimal commitments about Locke’s primary/secondary quality distinction are sufficient to derive some substantive conclusions about his positions on these issues, as well as that he is a general substance dualist.

In the last decade, there has been a notable upsurge in property (PD) and generic substance dualism (SD). By SD I mean the view that there is a spiritual substantial soul that is different from but variously related to its body. SD includes Cartesian, certain forms of late Medieval hylomorphic (e.g., Aquinas'), and Haskerian emergent SD. Nevertheless, some form of physicalism remains the majority view in philosophy of mind. Several fairly standard objections have been raised against SD, and (...) SDists have been preoccupied with these objections. As a result, a potent objection has not been given the attention it deserves. The purpose of this article is to fill that lacuna by raising the visibility of this objection and providing plausible responses to it. First, I shall clarify the explanatory–impotence challenge and, second, provide defeaters against it. Note that several of the issues to follow apply both to PD and SD. I will focus mostly on SD, but sometimes PD is a part of the discussion in that certain arguments for and against PD indirectly affect SD. When it is important for me to note that either SD or PD is specifically being addressed, I will notify the reader. (shrink)

I critically examine the view that Descartes’s independence conception (IC) of substance plays a crucial role in his “separability argument” for substance dualism. I argue that IC is a poisoned chalice. I do so by considering how an IC-based separability argument fares on two different ways of thinking about principal attributes. On the one hand, if we take principal attributes to be universals, then a separability argument that deploys IC establishes a version of dualism that is (...) unacceptably strong. On the other hand, if we take principal attributes to be tropes, then IC introduces challenges which undermine the argument. This is partly because the assumption of tropes makes it possible to distinguish several versions of substance dualism, versions which differ with respect to their degree of generality. I argue that taking principal attributes to be tropes makes it challenging to establish any of these versions by way of an IC-based separability argument. I conclude the paper by suggesting a way forward for the proponent of the separability argument. (shrink)

Substance dualism has received much attention from philosophers and theologians in contemporary literature. Whilst it may have been fashionable in the recent past to dismiss substance dualism as an unviable and academically absurd position to hold, this is no longer the case. My contention is not so much the merits of substance dualism in general, but a more specified variation of substance dualism. My specific contribution to the literature in this article is (...) that I argue for the viability of pure substance dualism as a more satisfactory option in contrast to compound or composite varieties of substance dualism. I put forth one argument and tease out the implications that make compound dualism less than satisfactory. I conclude that, minimally, more work is required on compound variations of dualism to make it a more appealing and a philosophically satisfactory option. (shrink)

In Galileo's Error, Philip Goff sets out a manifesto for a post-Galilean science of consciousness. Article four of the manifesto reads: 'Anti-Dualism: Consciousness is not separate from the physical world; rather consciousness is located in the intrinsic nature of the physical world.' I argue that there is an important sense of ‘dualism’ in which Goff’s arguments are not only compatible with but entail dualism, and not only dualism but substance dualism. Substance dualism, (...) in the sense I have in mind, is the view that (i) there are two sides to reality, a fundamentally mental side and a fundamentally nonmental side; and (ii) the fundamentally mental side consists of mental substances resembling Cartesian souls. I do not suggest that this is bad news for post-Galilean science of consciousness. My aim is rather to push for a certain view about what a theory of consciousness motivated by Goff’s arguments must look like. (shrink)

In their book on Descartes’s Changing Mind, Peter Machamer and J. E. McGuire argue that Descartes discarded dualism to embrace a kind of monism. Descartes famously proposed that there are two separate substances, mind and body, with distinct attributes of thought and extension. According to Machamer and McGuire, because of the limitations of our intellect, we cannot have insight into the nature of either substance. After reviewing their argument in some detail, I will argue that Descartes did not (...) relinquish his favorite doctrine but may have actually fooled himself about the nature of his dualism. It is my contention that the problem with Cartesian dualism stems from the definition of mind and body as substances and the role of their respective attributes—thought and extension—in the definition of substances.

Emergent substance dualism is explained in detail and several criticisms are raised against the view.

This is a companion to an earlier essay, "An Argument for Dualism from the Lived Experience of Time," in which I argue that our lived experience of being in space is best accounted for on a substance dualist ontology of the experiencing subject and a 3-dimensionalist account of time. Such an account excludes the metaphysical possibility of 4-dimensionalism as a literal, descriptive account of noumenal time inasmuch as it is incompatible with facts we know with greater certainty than (...) any scientific theory. (shrink)

In a sequel to the author's argument for dualism from the lived experience of time, this paper continues the line of thought initiated by in that study a bit further by considering the implications of our experience of being in space for dualism. I conclude that four-dimensionalism cannot accommodate the facts of our experience of ourselves as being in time - localized in space but not located there after the manner of a material thing. Substance dualism, (...) however, makes perfect sense of all these facts, which helps confirm the natural presumption in favor of that view. REVISED: March 24, 2022 with substantive changes.

In this essay, I discuss the standard objections to substance dualism and conclude that they are far less formidable than is usually supposed.

In this dissertation, I examine the implications of the problem of mental causation and what David Chalmers has dubbed the “ hard problem of consciousness” for competing accounts of the mind. I begin, in Chapter One, with a critical analysis of Jaegwon Kim’s Physicalism, or Something Near Enough. (2005) There, I maintain that Kim’s ontology cannot adequately address both the problem of mental causation and the “ hard problem of consciousness.” In Chapter Two, I examine the causal pairing problem for (...) substance dualism. I demonstrate both that the substance dualist can respond to the argument at no great cost, and that the pairing problem applies, with equal force, to the irreducible qualia posited on Kim’s account. Chapters Three and Four are devoted to what I take to be the central argument against any kind of dualism: the causal exclusion argument. In Chapter Three, I examine dualistic responses to the exclusion argument that grant the causal closure of the physical world. I note that these responses, though technically adequate, are nevertheless theoretically unpalatable. In addition to requiring the dualist to adopt unconventional attitudes towards causation, responses of this variety also have the unfortunate result of rendering libertarian freedom impossible. Finally, in Chapter Four, I turn my attention to the question of causal closure. I maintain that the causal closure of the physical world, though widely affirmed, is nevertheless extraordinarily difficult to support. In light of Hempel’s Dilemma, causal closure is either false, compatible with dualistic interaction, or unacceptably stipulative. There is, I maintain, no causal closure principle up to the tasks required by the causal exclusion argument. For that reason, I conclude that the dualist ought not to worry about causal closure.

According to the Christian doctrine of bodily resurrection, human persons will have an embodied existence in eternity. Many Christian materialists, especially Lynne Rudder Baker, Trenton Merricks, and Kevin Corcoran, argue that the doctrine of bodily resurrection creates serious problems for substance dualism (dualism). These critiques argued that bodily resurrection is made trivial by dualism, that dualism makes it difficult if not impossible to explain why we need to be embodied, or that dualism should be (...) rejected as bodily resurrection is better accounted for by a materialist view. As of yet, there has been no systematic analysis of these arguments in the literature. This paper fills that gap and argues that each of these objections to dualism fail. In making these arguments I make use of neo-Aristotelian metaphysics to provide a theory of embodiment for substance dualism. Accordingly, the body is a complex structural mode of the soul. The essence of the soul is the internal efficient cause and teleological guide of the functions and structure of the body. As such, the body is an ensouled physical structure, not a mere physical machine, but has both physical and non-physical aspects. (shrink)

Sometimes in philosophy one view engenders another. If you hold the first, chances are you hold the second. But it’s not always because the first entails the second. Sometimes the tie is less clear, less clean. One such tie is between substance dualism and anti-criterialism. Substance dualism is the view that people are, at least in part, immaterial mental substances. Anti-criterialism is the view that there is no criterion of personal identity through time. Most philosophers who (...) hold the first view also hold the second. In fact, many philosophers just assume that substance dualists ought to, or perhaps even have to, accept anti-criterialism. But I aim to show that this assumption is baseless. Substance dualism doesn’t entail, suggest, support, or in any way motivate anti-criterialism, and anti-criterialism confers no benefit on dualism. Substance dualists have no special reason—and, indeed, no good reason at all—to accept anti-criterialism. Or so I shall argue. My aim isn’t to defend substance dualism, nor is it to attack anti-criterialism. My aim is to show that, contrary to a long-standing trend, dualists needn’t be anti-criterialists. Nor, as it will turn out, should they be. (shrink)

I argue that in the Phaedo, Plato maintains that the soul is located in space and is capable of locomotion and of interacting with the body through contact. Numerous interpreters have dismissed these claims as merely metaphorical, since they assume that as an incorporeal substance, the soul cannot possess spatial attributes. But careful examination of how Plato conceives of the body throughout his corpus reveals that he does not distinguish it from the soul in terms of spatiality. Furthermore, assigning (...) spatial attributes to the soul plays an important role in Plato’s account of the relation of body and soul. (shrink)

This essay proposes a new interpretation of Clauberg’s account of the mind-body problem, against both occasionalist and interactionist readings. It examines his treatment of the mind-body relation through the lens of his theories of substance and cause. It argues that, whereas Clauberg embraces Descartes’s substance dualism, he retains a broadly scholastic theory of causation as the action of essential powers. On this account, mind and body are distinct, power-bearing substances, and each is a genuine secondary cause of (...) its own modifications. Between mental and bodily modes, however, there is only a special, divinely instituted correlation, but no causation. Clauberg’s view has the consequence that the conjunction of mind and body cannot be understood causally but only as the covariation of sensations and brain states, which he treats as mutually referring signs.

Descartes claims that God is a substance, and that mind and body are two different and separable substances. This paper provides some background that renders these claims intelligible. For Descartes, that something is real means it can exist in separation, and something is a substance if it does not depend on other substances for its existence. Further, separable objects are correlates of distinct ideas, for an idea is distinct (in an objective sense) if its object may be easily (...) and clearly separated from everything that is not its object. It follows that if our idea of God is our most distinct idea, as Descartes claims, then God must be a substance in the Cartesian sense of the term. Also, if we can have an idea of a thinking subject which does not in any sense refer to bodily things, and if bodily things are substances, then mind and body must be two different substances.

According to Nicole Oresme (c. 1320–1382), human beings, unlike all other animals, consist of two substances: a thinking substance and a sensing substance. This paper presents and explores the arguments Oresme uses to arrive at this position, which is unusual in medieval philosophical psychology and which at least superficially – though their methods are completely different – resembles what Descartes concluded about the nature of the human soul and body two and a half centuries later. The paper also (...) considers some moments of ambivalence in Oresme’s presentation, as well as unresolved difficulties, several of which have theological as well as philosophical implications.

Soul substance (jīva dravya) is ubiquitous but unseen. Driving force within each one of us, it has been, since time immemorial, a subject matter of research by philosophers, religious leaders and laity. Still, ambiguity and misconceptions prevail as regard its real nature. Some negate the existence of soul and attribute consciousness to the union of four basic substances – earth (prthvī), water (jala), fire (agni), and air (vāyu); death leads to its annihilation. Some believe it to be momentary, devoid (...) of self-existence. Still others consider it a product of illusion (māyā) or ignorance (avidyā) as all objects are manifestations of Brahma; only the one eternally undivided Brahma exists. All such conceptions are based on absolutism like: existence (bhāvaikānta) and non-existence (abhāvaikānta), non-dualism (advaita-ekānta) and separateness (prthaktva-ekānta), and permanence (nityatva-ekānta) and momentariness (ksanika-ekānta). Jaina epistemology goes beyond the superficial and examines objects of knowledge from all possible points of view. It asserts that the entity (dharmī) and its attributes (dharma) are neither absolutely dependent (āpeksika) nor absolutely independent (anāpeksika). Only an entity which has general (sāmānya – concerning the substance, dravya) and particular (viśesa – concerning the mode, paryāya) attributes can be the subject of knowledge. Substance without its modification and modification without its substance cannot be the subject of valid knowledge; only their combination can be the subject of knowledge. (shrink)

Elisabeth was the first of Descartes' interlocutors to press concerns about mind-body union and interaction, and the only one to receive a detailed reply, unsatisfactory though she found it. Descartes took her tentative proposal `to concede matter and extension to the soul' for a confused version of his own view: `that is nothing but to conceive it united to the body. Contemporary commentators take Elisabeth for a materialist or at least a critic of dualism. I read her instead as (...) a dualist of a different variety from Descartes: a forerunner of twenty-first century naturalistic dualism which calls for empirical investigation of the psychological and its posits to be taken just as seriously as physics and its posits. -/- I argue that Elisabeth, a keen scholar of mechanistic physics, objected not to substance dualism per se but to the residual Scholasticism of Descartes' account of mind-body causality and his dogmatism about principal attributes. She queried Descartes' categorisation of the `action' of thought as mind's principal attribute, and his identification of it with the merely negative property of immateriality, holding instead that further philosophical and empirical investigation into the nature of the mind is necessary. I problematise the materialist interpretation of Elisabeth with reference to later letters where she dismissed the materialist Objections of Hobbes and Gassendi and continued to urge further clarifications to Cartesian dualism. I explore Elisabeth's contrasting of statements of mechanistic physics with statements about thought, and her call for further investigation into the properties of the mind, and argue they mark her out as a forerunner of contemporary naturalistic dualism which proposes substance dualism as a best interpretation of recent psychology and of the difference in logical form between current physics and current psychology.

The contemporary debate around consciousness presents us (and often leads us to embrace) a specific current of thought: physicalism, which states that everything in our reality is physical1. In this paper I want to introduce the main points of the opposite view, dualism, according to which there are two different realms of reality: the mental and the physical one. In the introduction I give the main idea and sketch the general intuition behind dualism. In Section 1 I present (...) substance dualism and its more refined version, which is interactionism. In sub-section 1.1 I describe property dualism, which is the mainstream form of dualism adopted nowadays. In sub-sections 1.1.2 and 1.1.3 are proposed two variations of property dualism: epiphenomenalism and panpsychism. Finally, in Section 2 and its two sub-sections (2.1 and 2.2.) I recall Frank Jackson’s famous 1982 thought experiment and two classical objections to it, which are the Ability Hypothesis and the phenomenal concept strategy one. I conclude with a short reflection if we were to take under consideration the acceptance of dualism as an explanation of consciousness and its nature. PS: there's a mistake at page 12, as there's a note in the middle of the page that is not supposed to be there. (shrink)

Gilbert Ryle’s The Concept of Mind (1949/2002. Chicago, IL: University of Chicago Press) is generally considered a landmark in the quest to refute Cartesian dualism. The work contains many inspirational ideas and mainly posits behavioral disposition as the referent of mind in order to refute mind–body dualism. In this article, I show that the Buddhist theory of ‘non-self’ is also at odds with the belief that a substantial soul exists distinct from the physical body and further point out (...) similarities between the Buddhist outlook and Ryle’s ideas in three parts. First, I illustrate that Ryle’s ‘category mistake’ has certain points in common with the Buddhist refutation of ‘self’. Within the Buddhist framework, referents such as ‘mind’ and ‘self’ are merely imputed terms. The presumed existence of an independent substance such as a ‘soul’, when considered in isolation from the expedient usage of the term ‘mind’, can therefore also be viewed as a ‘category mistake’. Second, attempting to solve the questions of ‘what mind is’ and ‘how mind operates’ are two entirely different approaches to the study of mind. I argue that it is necessary to focus on ‘knowing-how’ rather than ‘knowing-that’, if we are to gain a more comprehensive understanding of mind and avoid any kind of category mistake such as those that follow from isolating the physical properties of brain or drawing inferences from a mystical soul. Third, I aim to show why investigating mind from the perspective of ‘dispositions’ of behavior is a valid approach. The Buddhist concept of karma-vāsanā elucidates the habitual tendency to act or not act in various situations. Based on this theory, I argue that the workings of the human mind bears strong links to the formation of karma and as such have important axiological implications that cannot be ignored. I conclude by pointing out that Ryle’s insightful ideas could in certain ways be complemented by the Buddhist theory of mind. In my view, his philosophy is not only a mediator between Analytic Philosophy and Phenomenology, but could perhaps also be seen as a mediator between traditional Eastern systems of thought and contemporary philosophies of mind.

One of the most serious challenges (if not the most serious challenge) for interactive psycho-physical dualism (henceforth interactive dualism or ID) is the so-called ‘interaction problem’. It has two facets, one of which this article focuses on, namely the apparent tension between interactions of non-physical minds in the physical world and physical laws of nature. One family of approaches to alleviate or even dissolve this tension is based on a collapse solution (‘consciousness collapse/CC) of the measurement problem in (...) quantum mechanics (QM). The idea is that the mind brings about the collapse of a superposed wave function onto one of its eigenstates. Thus, it is claimed, can the mind change the course of things without violating any law figuring in physical theory. I will first show that this hope is premature because energy and momentum are probably not conserved in collapse processes, and that even if this can be dealt with, the violations are either severe or produce further ontological problems. Second, I point out several conceptual difficulties for interactionist CC. I will also present solutions for those problems, but it will become clear that those solutions come at a high cost. Third, I shall briefly list some empirical problems which make life even harder for interactionist CC. I conclude with remarks about why no- collapse interpretations of QM don’t help either and what the present study has shown is the real issue for ID: namely to find a plausible integrative view of dualistic mental causation and laws of nature.

In this paper, I should like to argue against both eliminative materialism and substance/property dualism, aiming more specifically at the reductionist arguments offered by the Churchlands’ and Swinburne’s versions thereof, insofar as they undermine moral beliefs qua first-personish accounts dismissed as folk psychology by the former, as the latter regards them as supervening on natural events extendedly, that is, necessarily both ways of the biconditional linking mental and physical substances (for every A-substance x there is a B- (...) class='Hi'>substance y, such that necessarily if y exists x exists).

Mind, Brain, and Free Will, Richard Swinburne’s stimulating new book, covers a great deal of territory. I’ll focus on some of the positions Swinburne defends in the philosophy of mind. Many philosophers are likely to have reservations about the arguments he uses to defend them, and others will think his basic position is unmotivated. My goal in this brief discussion is to articulate some of the reasons why.

A post-Newtonian understanding of matter includes immaterial forces; thus, the concept of ‘physical’ has lost what usefulness it previously had and Cartesian dualism has, consequently, ceased to support a divide between the mental and the physical. A contemporary scientific understanding of mind that goes back at least as far as Priestley in the 18th century, not only includes immaterial components but identifies brain parts in which these components correlate with neural activity. What are we left with? The challenge is (...) no longer to figure out how a physical brain interacts with a nonphysical mind, but to try to unify theories of mind and theories of brain that to date do not share a single property. The challenge is enormous, but at least we can be quite clear about what its nature is, as there is no reason to be distracted by the idea of two distinct substances. In the present volume, many historical perspectives on the mind-body problem are discussed. In what follows, we follow major currents of thought regarding the mind-body problem so that it can be seen how we arrived at the modern conception that it makes sense only to talk about theory unification.

At a 2011 meeting of the Society of Christian Philosophers, N. T. Wright offered four reasons for rejecting the existence of soul. This was surprising, as many Christian philosophers had previously taken Wright's defense of a disembodied intermediate state as a defense of a substance dualist view of the soul. In this paper, I offer responses to each of Wright's objections, demonstrating that Wright's arguments fail to undermine substance dualism. In so doing, I expose how popular arguments (...) against dualism fail, such as dualism is merely an unwarranted influence of Greek culture on Christianity, and substance dualism is merely a soul-of-the-gaps hypothesis. Moreover, I demonstrate that Wright himself has offered a powerful reason for adopting substance dualism in his previous works. In conclusion I offer a view that explains why the human soul needs a resurrected body. (shrink)

According to the AI ensoulment hypothesis, some future AI systems will be endowed with immaterial souls. I argue that we should have at least a middling credence in the AI ensoulment hypothesis, conditional on our eventual creation of AGI and the truth of substance dualism in the human case. I offer two arguments. The first relies on an analogy between aliens and AI. The second rests on the conjecture that ensoulment occurs whenever a physical system is “fit to (...) possess” a soul, where very roughly this amounts to being physically structured in such a way that the system can meaningfully cooperate with the operations of the soul.

Philosophy is experiencing a resurgence of property (PD) and generic substance dualism (SD). One important argument for SD that has played a role in this resurgence is some version of a modal argument. Until recently, premise (3) of the argument (Possibly, I exist, and no wholly physical objects exist.) has garnered most of the attention by critics. However, more recently, the focus has also been on (2) (Wholly physical objects are essentially, wholly, and intrinsically physical and wholly spiritual (...) substances are essentially, wholly, and intrinsically immaterial.). Andrew Bailey has provided one of the best criticisms of (2) on offer. In what follows, I present and clarify one form of the argument and defend premise (2) by responding to important defeaters proffered by Andrew Bailey and his contingent physicalism. (shrink)

In this paper the author will assess Plato’s tripartite psychology in the light of his metaphysical account of μέγιστα γένη and One and Many, in order to further clarify the structure of his “dualism”. By doing so, the author will try to show that the tripartition is not a metaphysical conundrum of Plato’s thought and that it cannot be read in the light of Cartesian substance dualism, which is a noticeable approach in contemporary discussions. Aside of that, (...) Plato and Descartes are often understood as the main advocates of the substance dualism. Since the author finds the approach misleading, the aim of the paper is to point out the fundamental differences between the two, foremost by paying attention to the role of body in conceptual determination of soul.

Mereological nihilists hold that composition never occurs, so that nothing is ever a proper part of anything else. Substance dualists generally hold that we are each identical with an immaterial soul. In this paper, I argue that every popular objection to substance dualism has a parallel objection to composition. This thesis has some interesting implications. First, many of those who reject composition, but accept substance dualism, or who reject substance dualism and accept composition, (...) have some explaining to do. Secondly, one popular objection to mereological nihilism, one which contends that mereological nihilism is objectionable insofar as it is incompatible with the existence of people, is untenable.

Leibniz accepts causal independence, the claim that no created substance can causally interact with any other. And Leibniz needs causal independence to be true, since his well-known pre-established harmony is premised upon it. So, what is Leibniz’s argument for causal independence? Sometimes he claims that causal interaction between substances is superfluous. Sometimes he claims that it would require the transfer of accidents, and that this is impossible. But when Leibniz finds himself under sustained pressure to defend causal independence, those (...) are not the reasons that he marshals in its defense. Instead, deep into his long correspondence with Burchard de Volder, he gives a different sort of argument, one that has gone nearly unnoticed by commentators and has not yet been properly understood. In part, this is because the argument develops slowly over four years of correspondence. It emerges in early 1704, but it is formulated tersely and appears murky unless understood in light of Leibniz and De Volder’s tangled exchanges. There Leibniz argues that, on his distinctive ontology of an infinity of created substances, no two created substances could possibly causally interact, for roughly the same reasons that some Cartesians like De Volder deny interaction between minds and bodies on their substance dualist ontology. In this paper I draw out this lost argument, explain it and the metaphysics on which Leibniz builds it, and untangle Leibniz and De Volder’s exchanges concerning causation from which this argument results.

The link between human nature and human flourishing is undeniable. "A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit" (Matt. 7:18). The ontology of the human person will, therefore, ground the nature of human flourishing and thereby sanctification. Spiritual formation is the area of Christian theology that studies sanctification, the Spirit-guided process whereby disciples of Jesus are formed into the image of Jesus (Rom. 8:28-29; 2 Cor. 3:18; 2 Peter 3:18). Until the nineteenth century, (...) there was an overwhelming consensus among Christian thinkers that some form of mind-body (or soul-body) dualism is true of human beings. Recently, that consensus has eroded, and with it the availability of a shared body of knowledge about spiritual formation. Some Christian physicalists argue that dualism is incompatible with central elements of spiritual formation. Neuroscientist Warren Brown and psychologist Brad Strawn offer the only substantive account of spiritual formation from the view of Christian physicalism and its accompanying objections to dualism. It is on their arguments that this chapter focuses. We argue that Brown and Strawn fail to support their incompatibility thesis. Additionally, we argue that Christian physicalism stands in tension with important philosophical and theological foundations of Christian spiritual formation. In doing so we offer a specific form of dualism, the bodily soul view, and explain how this view illuminates the importance of embodiment, our neurological and social development, and hence the important physical aspects of Christian spiritual formation.

In a series of publications spanning over two decades, William Hasker has argued both that (1) human beings have souls and (2) these souls are not directly created by God but instead are produced by (or “emergent from”) a physical process of some sort or other. By contrast, an alternative view of the human person, endorsed by the contemporary Catholic Church, maintains that (1) human beings have souls but that (2*) each human soul is directly created by God rather than (...) produced by any kind of physical process. Hasker argues that given what we know from evolutionary biology, (2*) is a much less plausible position for believers in souls to take than (2) is. If Hasker is right, then there is a serious tension between the Church’s teaching about the human person and evolutionary biology. In this article, I challenge Hasker’s reasoning. I argue that those who hold the Catholic view that each human soul is directly created by God face no more difficulty reconciling their view with evolutionary biology than those who maintain, as Hasker does, that human souls are instead produced by some kind of physical process.

As substance dualism fell out of favor, philosophers became increasingly interested in making sense of mind in purely physicalist terms. Along the way, the physicalist project has hit a few snags. Perhaps the most popular challenge was presented by Frank Jackson’s Mary’s Room thought experiment, wherein Mary, a brilliant color scientist, comes to know all of the physical facts about color whilst confined to a black-and-white room. Once released, Mary is presented with a ripe tomato. The intuition is (...) that Mary, upon seeing a colored object for the first time, has learned something new, but what she has learned apparently cannot be accounted for by physicalism, thereby leaving an explanatory gap between mind and matter. There are those, like Joseph Levine, who believe the explanatory gap to be a necessary consequence of any physicalist theory of mind. I disagree, and in this dissertation, I aim to show that at least one physicalist theory of mind can close the gap. However, it requires embracing a theory that physicalists are hesitant to embrace: panpsychism. (shrink)

The mind-body problem is the problem of explaining how our mental states, events and processes—like beliefs, actions and thinking—are related to the physical states, events and processes in our bodies. A question of the form, ‘how is A related to B?’ does not by itself pose a philosophical problem. To pose such a problem, there has to be something about A and B which makes the relation between them seem problematic. Many features of mind and body have been cited as (...) responsible for our sense of the problem. Here I will concentrate on two: the fact that mind and body seem to interact causally, and the distinctive features of consciousness. A long tradition in philosophy has held, with René Descartes, that the mind must be a non-bodily entity: a soul or mental substance. This thesis is called ‘substance dualism’ (or ‘Cartesian dualism’) because it says that there are two kinds of substance in the world, mental and physical or material. One reason for believing this is the belief that the soul, unlike the body, is immortal. Another reason for believing it is that we have free will, and this seems to require that the mind is a non-physical thing, since all physical things are subject to the laws of nature. (shrink)

In Measuring the Immeasurable Mind: Where Contemporary Neuroscience Meets the Aristotelian Tradition, Matthew Owen argues that despite its nonphysical character, it is possible to empirically detect and measure consciousness. -/- Toward the end of the previous century, the neuroscience of consciousness set its roots and sprouted within a materialist milieu that reduced the mind to matter. Several decades later, dualism is being dusted off and reconsidered. Although some may see this revival as a threat to consciousness science aimed at (...) measuring the conscious mind, Owen argues that measuring consciousness, along with the medical benefits of such measurements, is not ruled out by consciousness being nonphysical. Owen proposes the Mind-Body Powers model of neural correlates of consciousness, which is informed by Aristotelian causation and a substance dualist view of human nature inspired by Thomas Aquinas, who often followed Aristotle. In addition to explaining why there are neural correlates of consciousness, the model provides a philosophical foundation for empirically discerning and quantifying consciousness. En route to presenting and applying the Mind-Body Powers model to neurobiology, Owen rebuts longstanding objections to dualism related to the mind-body problem. With scholarly precision and readable clarity, Owen applies an oft forgotten yet richly developed historical vantage point to contemporary cognitive neuroscience. (shrink)

After rejecting substance dualism, some naturalists embrace patternism. It states that persons are bodies and that bodies are material machines running abstract person programs. Following Aristotle, these person programs are souls. Patternists adopt four-dimensionalist theories of persistence: Bodies are 3D stages of 4D lives. Patternism permits at least six types of life after death. It permits quantum immortality, teleportation, salvation through advanced technology, promotion out of a simulated reality, computational monadology, and the revision theory of resurrection.

A main element in Richard Swinburne’s (2019) argument for substance dualism concerns the conditions of a person’s continued existence over time. In this commentary I aim to question two things: first, whether the kind of imaginary cases that Swinburne relies on to make his case should be accorded the kind of weight he supposes; and second, whether philosophers should be concerned to give any substantial theory, of the sort that dualism and its competitors are apparently meant to (...) provide, to explain the conditions of personal identity after all. My suggestion, instead, will be that the concept of a person’s continued existence is better taken as philosophically unanalyzable. (shrink)

Zu den Anliegen dieses Beitrags zählt zum einen die Diskussion einiger aktuellerer Argumente gegen die Vereinbarkeit eines Dualismus von Eigenschaften mit einem (Substanz-)Physikalismus und zum anderen in einer Präsentation und Verteidigung des von E. J. Lowe (1950-2014) vertretenen (Nicht-Cartesianischen) Substanzendualismus. -/- Erschienen in: Patricia Wallusch/ Heinrich Watzka (Hrsg.): Verkörpert existieren. Ein Beitrag zur Metaphysik menschlicher Personen, Münster: Aschendorff 2015, pp. 59-70. ISBN 978-3-402-11892-4 .

A well-known problem seems to beset views on which humans are essentially material, but where I can survive my death: they seem incoherent or reducible to substance dualism. Thomas Aquinas held a unique hylomorphic view of the human person as essentially composed of body and soul, but where the human soul can survive the death of the body. ‘Survivalists’ have argued that, post mortem, a human person comes to be composed of their soul alone. ‘Corruptionists’ point to Thomas’ (...) texts, where he claims that the human person ceases to exist at death and only a part of one – albeit a special part – persists. With some help from Elizabeth Anscombe, I show that a denial of the semantic and metaphysical assumptions made by both parties on that point gives us a much better solution to the controversy over the personality of the separated soul.

Qualia are defined as subjective or private feelings associated with sensory and other experiences. This article argues that private feelings might be expressed by or in a personal brain and discusses possible neurobiological implications. Four issues are considered: Functional dualism implies that mental functions are realized as emergent properties of the brain. In practice, functional dualism is compatible with both substance dualism and pan-psychism. The (adult) human brain is the product of biological and environmental processes, including (...) cultural influences, and is individually unique. Part of the cerebral neuronal processing is molded by individual memories and previous experiences. Biological processes underlying the realization of qualia, including neural activities, escape conscious control. The temporal expression of qualia is in part consciously channeled by, for instance, actual situations and cultural habits. Neuroscientific explanations refer to general principles of nature, rather than to individual phenomena. Hence, future neurobiological approaches might aim to identify which neuronal processes are involved in qualia and how. It seems illusory to explain each quale. (shrink)

Descartes's "conceivability argument" for substance-dualism is defended against Arnauld's criticism that, for all he knows, Descartes can conceive himself without a body only because he underestimates his true essence; one could suggest with equal plausibility that it is only for ignorance of his essential hairiness that Descartes can conceive himself as bald. Conceivability intuitions are defeasible but special reasons are required; a model for such defeat is offered, and various potential defeaters of Descartes's intuition are considered and rejected. (...) At best though Descartes shows the separability of mind from body, not (as he claims) their actual separateness. (shrink)
