The major Western monotheisms, and Christianity in particular, are often supposed to be committed to a substance dualism of a Cartesian sort. Aquinas, however, has an account of the soul which is non-Cartesian in character. He takes the soul to be something essentially immaterial or configurational but nonetheless realized in material components. In this paper, I argue that Aquinas’s account is coherent and philosophically interesting; in my view, it suggests not only that Cartesian dualism isn’t essential to (...) Christianity but also that the battle lines between dualism and materialism are misdrawn. (shrink)

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.

Rene Descartes's argument begins from one obviously true premise that (at the time when he was considering this argument) Descartes is thinking. It then proceeds by means of two principles about what is “conceivable” to the conclusion that Descartes is essentially “a thinking substance distinct from his body, which he calls his 'soul'”. This chapter looks in more detail at Descartes's argument. It explains some of the terminology which Descartes uses. Descartes consists of two parts ‐ an essential part (...) (his soul) and an inessential part (his body). And, Descartes would add, what applies to Descartes, applies to all other humans. Hence substance dualism ‐ humans consist of two substances, a soul (the essential part) and a body (the inessential part). The chapter illustrates how there can be Descartes's propositions whose metaphysical modality differs from their logical modality. (shrink)

This chapter aims to separate the caricatures of dualism from a serious philosophical and theological view of human, and nonhuman animal nature. It addresses one of the key sources for discontent with substance dualism: the assumption that people have a clear, problem‐free understanding of what it is to be physical. The chapter discusses author's argument for why people should believe that human persons are not numerically identical with their bodies. It also offers reasons why materialism is unacceptable (...) in terms of mental‐physical identity. The chapter defends the possibility of persons ceasing to be while their bodies survive, and persons surviving death despite the annihilation of their bodies. It proposes that the way forward is to consider whether there is a reason to believe that what people know in their experience is the very same thing as what most physicalists claim is physical: their brains and brain processes or their bodies as a whole.

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.

Mele uses survey methods of experimental philosophy to argue that folk notions of freedom and responsibility do not really require any dubious mind–body dualism. In his comment, Nadelhoffer questions Mele's interpretation of the experiments and adds contrary data of his own. Vargas then suggests that Mele overlooks yet another threat to free will—sourcehood. Mele replies by reinterpreting Nadelhoffer's data and rejecting Vargas’ claim that free will requires sourcehood.

The appearance of consciousness in the world is an amazing and puzzling fact in its own right. Indeed, consciousness is one of the most mystifying features of the cosmos. The unity of consciousness is something that cries out for analysis and explanation as well. This chapter provides a way of relating the three types of unity: objectual phenomenal unity; subject phenomenal unity; and subsumptive phenomenal unity. According to Tim Bayne and David Chalmers, this sort of unity is irrelevant for investigating (...) the nature of consciousness' unity because it is trivially true by definition and tells us nothing about consciousness. Many thinkers, including Bayne himself, believe there is no self or subject that unifies consciousness. Bayne's position amounts to a bunch of mere assertions that allow him to avoid an obvious solution: substance dualism. (shrink)

This book analyses anthropological debates on "relationism" (referring to methodological and theoretical issues) and sets out to reconsider these discussions with regards to the notion of "substance" (generally associated with the body). Reflecting on the philosophical origins and implications of these two concepts, the author aims to bring them to the heart of contemporary anthropological discourse and addresses the erasure (or blurring) of "substance" in favour of "relation." The argument put forward is that the conceptual pairing of " (...) class='Hi'>substance-relation" should be substituted for the "nature-culture" dualism that has been dominant in structural anthropology. The chapters engage with the work of scholars such as Philippe Descola, Eduardo Viveiros de Castro and Wang Mingming as part of a decentring and questioning of the tradition in which anthropology is rooted. The book also considers the role that the anthropology of China plays in the re-evaluation of the relationship between relation and substance. The concept of "submutance" is introduced with Chinese ethnographic material to explore the possibility of moving beyond the relation-substance dualism of Western heritage. This is valuable reading for scholars interested in the theory and history of anthropology. (shrink)

Substance dualism is the view that humans are essentially immaterial souls, and that conscious events are events in that soul. This chapter considers the arguments for and against this view. It argues that such questions as ‘Would I have existed if my mother's egg had been fertilized by a different though genetically identical sperm from my father?’ must have a sharp yes-or-no answer, but that they would not have a sharp answer if being me consisted simply of being (...) made of similar genetic material and having a similar conscious life.

Currently, there remains an aversion for substance dualism in both philosophical and theological literature. However, there has been a renewed interest in substance dualism within philosophical literature. In the present article, I advance substance dualism as a viable position that persuasively accounts for the Scriptural and theological data within Christian thought. I make a specific argument in favor of a metaphysically simple substance. Along the way, I note the overlap between the philosophical and (...) theological literature and suggest that a simple soul as substance is a metaphysical presupposition grounding the data. (shrink)

n this paper I would like to defend the three interconnected claims. The first one is based on that fact that the definition of substance dualism proposed recently by Dean Zimmerman needs some essential adjustments in order to capture the genuine spirit of this doctrine. In this paper I will formulate the conditions for the genuine substance dualism in contrast to quasi-dualisms and provide the definition for the genuine substance dualism which I consider to (...) be more appropriate than the Zimmerman's one. The second claim is that none of the contemporary forms of substance dualism is able to provide the satisfactory evaluation of the conscious subjectivity. To support this claim I can present two arguments: the first one is against the Cartesian Dualism, and another is against the Emergent Dualism. The third claim, I believe, derives from the two mentioned above: if the dualistic arguments against the ability of physicalist theories to provide the sound account for the unity of a subject of consciousness are persuasive enough, then, in order to acquire the more adequate account of the unity of conscious subject, we should look more closely towards such forms of quasi-dualism as spiritualism or the broad Aristotelian view of human persons.

In a number of places, Richard Swinburne has defended the logical possibility of perception without a body; and has inferred from this logical possibility that substance dualism is true. I challenge his defence of disembodied perception by arguing that a disembodied perceiver would not be able to distinguish between perceptions and hallucinations. I then claim that even if disembodied perception were possible, this could not be used to support substance dualism: such an inference would be either (...) invalid or question-begging. (shrink)

Events are the instantiations of properties in substances at times. A full history of the world must include, as well as physical events, mental events (ones to which the substance involved has privileged access) and mental substances (ones to the existence of which the substance has privileged access), and, among the latter, pure mental substances (ones which do not include a physical substance as an essential part). Humans are pure mental substances. An argument for this is that (...) it seems conceivable that I could exist without my body. An objection to this argument is that ‘I’ refers to my body, and so what seems conceivable is not metaphysically possible. My response to this objection is that ‘I’ is an informative designator and so necessarily we know to what it refers, and it does not refer to my body. (shrink)

There are two tasks for any adequate philosophy of mind: (1) articulate one’s position and explain why dualism is the commonsense view; (2) defend one’s position. I believe that there is an argument that simultaneously satisfies both desiderata in a non–ad hoc way and, thus, the argument can thereby claim the virtue of theoretical simplicity in its favor. In what follows, I shall present the argument and defend its most crucial premise, respond to three criticisms that have been raised (...) against it, and draw out one dialectical implication of the argument.

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.

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)

The first stems from the fact that the definition of substance dualism recently proposed by Dean Zimmerman needs some essential adjustments in order to capture the genuine spirit of the doctrine.

Non-Cartesian substance dualism maintains that persons or selves are distinct from their organic physical bodies and any parts of those bodies. It regards persons as ‘substances’ in their own right, but does not maintain that persons are necessarily separable from their bodies, in the sense of being capable of disembodied existence. In this paper, it is urged that NCSD is better equipped than either Cartesian dualism or standard forms of physicalism to explain the possibility of mental causation. (...) A model of mental causation adopting the NCSD perspective is proposed which, it is argued, is consistent with all that is currently known about the operations of the human central nervous system, including the brain. Physicalism, by contrast, seems ill-equipped to explain the distinctively intentional or teleological character of mental causation, because it effectively reduces all such causation to ‘blind’ physical causation at a neurological level.

You have a body, but you are a soul or self. Without your body, you could still exist. Your body could be and perhaps is outlasted by the immaterial substance which is your soul or self. Thus the substance dualist. Most substance dualists are Cartesians. The self, they suppose, is essentially conscious: it cannot exist unless it thinks or wills or has experiences. In this paper I sketch out a different form of substance dualism. I (...) suggest that it is not consciousness but another immaterial feature which is essential to the self, a feature in one way analogous to a non-dispositional taste. Each self has moreover a different feature of this general kind. If this is right then simple and straightforward answers are available to some questions which prove troublesome to the Cartesian, consciousness-requiring type of substance dualist. I mean the questions, How can the self exist in dreamless sleep?, What distinguishes two simultaneously existing selves, and What makes a self the same self as a self which exists at some other time?

Non‐Cartesian substance dualism is a position in the philosophy of mind concerning the nature of the mind‐body relation or, more exactly, the person‐body relation. Whereas Cartesian substance dualism takes subjects of experience to be necessarily immaterial and indeed nonphysical substances, non‐Cartesian substance dualism does not insist on this. This distinctive feature of non‐Cartesian substance dualism gives it certain advantages over Cartesian dualism, without compelling it to forfeit any of the intuitive appeal (...) that attaches to its more traditional rival. In this chapter, the author's own view is that the self is indeed a simple substance. The simplicity of the self goes some way toward explaining its unity, including the unity of consciousness that characterizes its normal condition. A divided consciousness is in principle consistent with self‐identity: what is not consistent with this is a radical disunity of beliefs and values, manifested in a radical inconsistency of thought and action.

A groundbreaking collection of contemporary essays from leading international scholars that provides a balanced and expert account of the resurgent debate about substance dualism and its physicalist alternatives. Substance dualism has for some time been dismissed as an archaic and defeated position in philosophy of mind, but in recent years, the topic has experienced a resurgence of scholarly interest and has been restored to contemporary prominence by a growing minority of philosophers prepared to interrogate the core (...) principles upon which past objections and misunderstandings rest. As the first book of its kind to bring together a collection of contemporary writing from top proponents and critics in a pro-contra format, The Blackwell Companion to Substance Dualism captures this ongoing dialogue and sets the stage for rigorous and lively discourse around dualist and physicalist accounts of human persons in philosophy. Chapters explore emergent, Thomistic, Cartesian, and other forms of substance dualism—broadly conceived—in dialogue with leading varieties of physicalism, including animalism, non-reductive physicalism, and constitution theory. Loose, Menuge, and Moreland pair essays from dualist advocates with astute criticism from physicalist opponents and vice versa, highlighting points of contrast for readers in thematic sections while showcasing today’s leading minds engaged in direct debate. Taken together, essays provide nuanced paths of introduction for students, and capture the imagination of professional philosophers looking to expand their understanding of the subject. Skillfully curated and in touch with contemporary science as well as analytic theology, The Blackwell Companion to Substance Dualism strikes a measured balanced between advocacy and criticism, and is a first-rate resource for researchers, scholars, and students of philosophy, theology, and neuroscience.

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.

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.

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 monograph presents an interpretation of Descartes's dualism, which differs from the standard reading called 'classical separatist dualism' claiming that the mind can exist without the body. It argues that, contrary to what it is commonly claimed, Descartes’s texts suggest an emergent creationist substance dualism, according to which the mind is a nonphysical substance (created and maintained by God), which cannot begin to think without a well-disposed body. According to this interpretation, God’s laws of nature (...) endow each human body with the power to be united to an immaterial soul. While the soul does not directly come from the body, the mind can be said to emerge from the body in the sense that it cannot be created by God independently from the body. The divine creation of a human mind requires a well-disposed body, a physical categorical basis. This kind of emergentism is consistent with creationism and does not necessarily entail that the mind cannot survive the body. This early modern view has some connections with Hasker’s substance emergent dualism (1999). Indeed, Hasker states that the mind is a substance emerging at one time from neurons and that consciousness has causal powers which effects cannot be explained by physical neurons. An emergent unified self-existing entity emerges from the brain on which it acts upon. For its proponents, Hasker’s view explains what Descartes’s dualism fails to explain, especially why the mind regularly interacts with one and only one body. After questioning the notion of emergence, the author argues that the theory of emergent creationist substance dualism that she attributes to Descartes is a more appropriate alternative because it faces fewer problems than its rivals. This monograph is valuable for anyone interested in the history of early modern philosophy and contemporary philosophy of mind. (shrink)

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)

This article presents arguments and evidence that run counter to the widespread assumption among scholars that humans are intuitive Cartesian substance dualists. With regard to afterlife beliefs, the hypothesis of Cartesian substance dualism as the intuitive folk position fails to have the explanatory power with which its proponents endow it. It is argued that the embedded corollary assumptions of the intuitive Cartesian substance dualist position (that the mind and body are diff erent substances, that the mind (...) and soul are intensionally identical, and that the mind is the sole source of identity) are not compatible with cultural representations such as mythologies, funerary rites, iconography and doctrine as well as empirical evidence concerning intuitive folk reasoning about the mind and body concerning the afterlife. Finally, the article suggests an alternative and more parsimonious explanation for understanding intuitive folk representations of the afterlife. (shrink)

The common materialist view that a functional account of intentionality will eventually be produced is rejected, as is the notion that intentional states are multiply realisable. It is argued also that, contrary to what many materialists have held, the causation of behaviour by intentional states rules out the possibility of a complete explanation of human behaviour in physical terms, and that this points to substance dualism. Kant's criticism of the Cartesian self as a substance, endorsed by P. (...) F. Strawson, rests on a misinterpretation of Descartes. The so-called , which Kim sees to be the crucial objection to substance dualism, is examined, and Kim's arguments are rejected. (shrink)

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

At the end of the 19th Century, substance dualism-roughly, the thesis that the human person is comprised of a substantial immaterial soul and a physical body-was widespread. Materialism was not a live option. As U.T. Place observed, [Ever] since the debate between Hobbes and Descartes ended in apparent victory for the latter, it was taken more or less for granted that whatever answer to the mind-body problem is true, materialism must be false. This sociological fact changed quickly bringing (...) about what William James described as "the evaporation of the definite soul-substance." Arthur O. Lovejoy deemed the 20th century as "the Age of the Great Revolt against Dualism." The inevitable defeat of substance dualism was assumed a foregone conclusion. Gilbert Ryle had, in the words of Daniel Dennett, "danced quite a jig on the corpse of Cartesian dualism.". (shrink)

In his Rules for the Direction of the Mind, Descartes elevates arithmetic and geometry to the status of paradigms for all the sciences, because of the potential for certainty in their results. This emphasis on certainty is present throughout the Cartesian corpus, but in the Rules and other early works the substance dualism characteristic of Cartesian philosophy is not as obvious. However, when several key concepts from this early work are considered together, it becomes clear that Cartesian (...) class='Hi'>dualism necessarily follows. The most important of these concepts are: Descartes’s rejection of the Scholastic theory of sense data in favor of a telecommunicative theory of perception; his innovative reconceptualization of mathematics in which he treats number and magnitude as interchangeable, making use of the symbolism of algebra; his frequent use of visual metaphors to describe perception in general, as well as other cognitive activity. It is in consideration of this third point that Descartes’s treatment of the imagination shows its importance, for the relationship of the imagination to the intellect parallels that of geometric figures to algebraic formulae. Though the role of the imagination in the Rules seems to make the status of a dualist ontology in this work more ambiguous, this paper will argue that in fact it is precisely in the treatment of imagination that one can find the traces of a fully developed substance dualism.

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)

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.

The problem of divine agency and action is analogous to the problem of human agency and action: How is such agency possible in the absence of a dualistic causal interaction between disparate orders of being? This paper explores nondualistic accounts of divine agency that assert the following: (1) physical monism, (2) antireductionism, (3) physical realization, and (4) divine causal realism. I conclude that a robustly causal deity is incompatible with nonddualism's affirmation of physical monism. Specifically, I argue the incoherence of (...) nondualistic strategies that advocate divine information transfer without energy transfer or the divine downward causation of physical events. Furthermore, I claim that the principle of explanatory exclusion makes any nondualistic, noninterventionist account of divine agency highly dubious. Finally, I suggest that Judaism, Christianity, and Islam can avoid a causally inert deity only if they are willing to deny the current presumption of the causal closure of the physical. (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 early modern period one can find unity of consciousness arguments in the writings of Rene Descartes and G. W. Leibniz, and in the recent literature they have been defended by David Barnett, William Hasker, and Richard Swinburne (among others). Descartes's unity of consciousness argument for dualism is to be found in the sixth of his Meditations on First Philosophy. Descartes claims that his unity of consciousness argument was itself sufficient to establish substance dualism. Swinburne's central (...) line of argument involves deploying a number of puzzle cases. He argues that our intuitions about these cases can be accommodated only by adopting a “further fact” view of the self, according to which the continued existence of a person over time consists in the continued existence of a mental substance, and “it is metaphysically possible that the substance acquires a totally new body, totally new apparent memories, and character”.

I argue in this essay that Richard Swinburne’s revised version of Descartes’ argument in chapter 5 of his Are We Bodies or Souls? does not quite get him to the conclusion that he requires, but that a modified version of his treatment of personal identity will do the trick. I will also look critically at his argument against epiphenomenalism, where, once again, I share his conclusion but have reservations about the argument.

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)
