In this paper, I develop an ontological position according to which substances such as you and I have no substantial parts. The claim is not that we are immaterial souls. Nor is the claim that we are “human atoms” co-located with human organisms. It is, rather, that we are macrophysical objects that are, in the relevant sense, simple. I contend that despite initial appearances, this claim is not obviously false, and I defend it by showing how much work it can (...) do. (shrink)

Timothy Williamson thinks that every object is a necessary, eternal existent. In defense of his view, Williamson appeals primarily to considerations from modal and tense logic. While I am uncertain about his modal claims, I think there are good metaphysical reasons to believe permanentism: the principle that everything always exists. B-theorists of time and change have long denied that objects change with respect to unqualified existence. But aside from Williamson, nearly all A-theorists defend temporaryism: the principle that there are temporary (...) existents. I think A-theorists are better off without this added commitment, but I will not argue for that in any great detail here. Instead, I will contend that a very tempting A-theoretic argument for temporaryism is unsound. In the first half of the paper, I will develop the Moorean “common sense” argument for temporaryism and dispute its central premise, namely that temporaryism is a valid generalization from highly plausible beliefs about change. I will argue that given the pervasive vagueness in our ordinary beliefs about change and the background commitments of all A-theories, no party can claim to be the common sense view because no party can accommodate most of our common sense beliefs about change in existence. In the second half of the paper, I will propose a permanentist A-theory that explains all change over time as a species of property change. I call it the minimal A-theory, since it dispenses with the change in existence assumption. As we'll see, the permanentist alternative performs well enough in explaining our ordinary beliefs about change, and it has better prospects for answering some objections commonly levied against A-theories.

There has in recent years been a significant surge of interest in non-materialist accounts of the mind. Property dualists hold that all substances (concrete particulars that persist over time) are material, but mental properties are distinct from physical properties. Substance dualists maintain that the mind or person is a non-material substance. This article considers the prospects for substance dualism given the current state of the debate. The best known type of substance dualism, Cartesian dualism, has traditionally faced a number of (...) objections, but many contemporary philosophers have sought to avoid these by formulating novel versions of the view. I identify three central claims held in common by all forms of substance dualism, consider recent arguments for these claims, and assess how successfully different types of substance dualism respond to the traditional objections. I argue that most contemporary forms of the view still face one or more of three major challenges, from bundle theories of the self, from the recently developed “phenomenal concepts strategy”, and from worries about explanatory simplicity.

Most answers to the mind-body problem are claims about the nature of mental properties and substances. But advocates of non-reductive physicalism have generally neglected the topic of the nature of substance, quickly nodding to the view that all substances are physical, while focusing their intellectual energy on understanding how mental properties relate to physical ones. Let us call the view that all substances are physical or are exhaustively composed of physical substances substance physicalism (SP). Herein, I argue that non-reductive physicalism (...) (NRP) cannot uphold substance physicalism and is thereby false. For NRP faces a mind problem: its commitment to property irreducibility prevents that which bears the mental properties—the mind, or on some views, the self or person—from being a physical thing.

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)

In recent publications, Michael Tye and Alva Noë have claimed that there is a sense in which a tilted plate looks round and another sense in which it looks elliptical. This paper argues that their proposal faces decisive objections. On Tye and Noë's account of ordinary, veridical perception, appearances are in constant conflict. As a characterization of ordinary visual experience, this cannot be correct. I examine various responses to this criticism, and conclude that they all fail. I then argue that (...) Noë's account has the further, unintended and undesirable consequence of promoting a version of the sense-datum theory. (shrink)

Many philosophers say that two or more people or thinking beings could share a single human being in a split‐personality case, if only the personalities were sufficiently independent and individually well integrated. I argue that this view is incompatible with our being material things, and conclude that there could never be two or more people in a split‐personality case. This refutes the view, almost universally held, that facts about mental unity and disunity determine how many people there are. I suggest (...) that the number of human people is simply the number of appropriately endowed human animals. (shrink)

In this paper I shall explore a novel alternative to these familiar views. In his recent book Sub ects of Ex erience, E. J. Lowe argues, as many others have done before, that you and I are not animals. It follows from this, he says, that we must be simple substances without parts. That may sound like Cartesian dualism. But Lowe is no Cartesian. He argues from premises that many present-day materialists accept. And he claims that our being mereologically simple (...) is consistent with our having such paradigmatically physical properties as being six feet tall and weighing 160 pounds. You and I, he claims, are mereological atoms shaped like human beings. (shrink)

In recent years, emergentism has resurfaced as a possible method by which to secure autonomous mental causation from within a physicalistic framework. Critics argue, however, that emergentism fails, since emergentism entails that effects have sufficient physical causes, so they cannot also have distinct mental causes. In this paper I argue that this objection may be effective against supervenient emergentism, but it is not established that it is effective against mereological emergentism. In fact, after demonstrating that two founding emergentists, Samuel Alexander (...) and C. Lloyd Morgan, are mereological emergentists, I show how mereological emergentism provides fresh responses to the causal exclusion problem. (shrink)

Many metaphysicians tell us that our world is one in which persisting objects are four-dimensionally extended in time, and persist by being partially present at each moment at which they exist. Many normative theorists tell us that at least some of our core normative practices are justified only if the relation that holds between a person at one time, and that person at another time, is the relation of strict identity. If these metaphysicians are right about the nature of our (...) world, and these normative theorists are right about what justifies our normative practices, then we should be error theorists about the justification of at least some of our core normative practices and in turn, arguably we should eliminate those practices for which justification is lacking. This paper offers a way of resolving the tension between these two views that does not lead into the grips of error theory. It is a way that is amenable to “exceptionists” about persons: those who think there is something special about persons and the first-person perspective; that personhood cannot be explained naturalistically, and the first-person perspective is naturalistically irreducible. The conclusion is thus a conditional: given that one is an exceptionist, an attractive way to resolve this tension is to embrace the view that persons are sui generis ontological kinds. (shrink)

In the first part, the paper describes in detail the classical conception of intentionality which was expounded in its most sophisticated form by Edmund Husserl. This conception is today largely eclipsed in the philosophy of mind by the functionalist and by the representationalist account of intentionality, the former adopted by Daniel Dennett and David Chalmers, the latter by John Searle and Fred Dretske. The very considerable differences between the classical and the modern conceptions are pointed out, and it is argued (...) that the classical conception is more satisfactory than the two modern ones, not only regarding phenomenal adequacy, but also on the grounds of epistemological considerations. In the second part, the paper argues that classical intentionality is not naturalizable, that is, physicalizable. Since classical intentionality exists (in the experiences that display it), the non-naturalizability of classical intentionality implies psychophysical dualism. (shrink)

In this paper I consider the relationship between the spatial properties of visual perceptual experience and the sense-datum inference. I argue that the sense datum inference should be accepted if spatial properties are not merely intentionally present in such experiences. This result serves to underline the seriousness of the difficulties that are presented to direct realism by a particular class of illusory spatial experiences based on the geometry of visual perceptual experience. In light of these considerations I argue that it (...) is a constraint on direct realism that the underlying spatial character of visual perceptual experiences must be the same as that of the physical world.

Martine Nida-Rümelin has argued recently for subject-body dualism on the basis of reflections on the possibility of survival in fission cases from the literature on personal identity. The argument focuses on the claim that there is a factual difference between the claims that one or the other of two equally good continuers of a person in a fission case is identical with her. I consider three interpretations of the notion of a factual difference that the argument employs, and I argue (...) that on each of them the argument either begs the question or is unsound. (shrink)

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.

Towards the end of Chapter XXI of Book II of the Essay Concerning Human Understanding, Locke remarks, with all the appearance of sincerity and genuine modesty, that.

The paper examines the Cartesian and the Strawsonian answers to the question of why self-applied and other-applied mental predicates mean the same. While these answers relate to different, complementary aspects of this question, they seem and are usually considered as incompatible. Indeed, their apparent incompatibility constitutes a major objection to the Cartesian answer. A primary aim of the paper is to show that the Strawsonian answer does not pose a real problem to the Cartesian answer. Unlike other attempts to show (...) this, the paper does not seek to undermine the Strawsonian answer. Indeed, its second aim is to defend this answer against these other attempts. The paper’s strategy in defending the Cartesian answer is to show that the framework underlying this answer can — indeed, for internal reasons, must — accommodate the Strawsonian answer. By showing this, the paper also shows that a Cartesian framework can provide a comprehensive answer to the aforementioned question, which is its third aim. (shrink)

Sydney Shoemaker leads today’s “neo-Lockean” liberation of persons from the conservative animalist charge of “neo-Aristotelians” such as Eric Olson, according to whom persons are biological entities and who challenge all neo-Lockean views on grounds that abstracting from strictly physical, or bodily, criteria plays fast and loose with our identities. There is a fundamental mistake on both sides: a false dichotomy between bodily continuity versus psychological continuity theories of personal identity. Neo-Lockeans, like everyone else today who relies on Locke’s analysis of (...) personal identity, including Derek Parfit, have either completely distorted or not understood Locke’s actual view. Shoemaker’s defense, which uses a “package deal” definition that relies on internal relations of synchronic and diachronic unity and employs the Ramsey–Lewis account to define personal identity, leaves far less room for psychological continuity views than for my own view, which, independently of its radical implications, is that (a) consciousness makes personal identity, and (b) in consciousness alone personal identity consists—which happens to be also Locke’s actual view. Moreover, the ubiquitous Fregean conception of borders and the so-called “ambiguity of is” collapse in the light of what Hintikka has called the “Frege trichotomy.” The Ramsey–Lewis account, due to the problematic way Shoemaker tries to bind the variables, makes it impossible for the neo-Lockean ala Shoemaker to fulfill the uniqueness clause required by all such Lewis style definitions; such attempts avoid circularity only at the expense of mistaking isomorphism with identity. Contrary to what virtually all philosophers writing on the topic assume, fission does not destroy personal identity. A proper analysis of public versus perspectival identification, derived using actual case studies from neuropsychiatry, provides the scientific, mathematical and logical frameworks for a new theory of self-reference, wherein “consciousness,” “self-consciousness,” and the “I,” can be precisely defined in terms of the subject and the subject-in-itself.

The conservation laws do not establish the central premise within the argument from causal overdetermination – the causal completeness of the physical domain. Contrary to David Papineau, this is true even if there is no non-physical energy. The combination of the conservation laws with the claim that there is no non-physical energy would establish the causal completeness principle only if, at the very least, two further causal claims were accepted. First, the claim that the only way that something non-physical could (...) affect a physical system is by affecting the amount of energy or momentum within it, or redistributing the energy and momentum within it. Second, the claim that redistribution of energy and momentum cannot be brought about without supplying energy or momentum. Both of these claims, however, are exceedingly difficult to defend in the context of the argument. (shrink)

Mentalistic (or Lockean) accounts of personal identity are normally formulated in terms of causal relations between psychological states such as beliefs, memories, and intentions. In this paper we develop an alternative (but still Lockean) account of personal identity, based on phenomenal relations between experiences. We begin by examining a notorious puzzle case due to Bernard Williams, and extract two lessons from it: first, that Williams's puzzle can be defused by distinguishing between the psychological and phenomenal approaches, second, that so far (...) as personal identity is concerned, it is phenomenal rather than psychological continuity that matters. We then consider different ways in which the phenomenal approach may be developed, and respond to a number of objections. That with which the consciousness of this present thinking thing can join itself, makes the same person, and is one self with it, and with nothing else; and so attributes to itself and owns all the actions of that thing, as its own, as far as that consciousness reaches, and no farther; as every one who reflects will perceive.

The subjective character of a given experience leaves open the question of its precise status. If it looks to a subject K as if there is an object of a kind F in front of him, the experience he is having could be veridical, or hallucinatory. Advocates of the Causal Theory of perception (whom I shall call.

In this paper I shall attempt to argue for the simple view of personal identity. I shall first argue that we often do have warrant for our beliefs that we exist as continuing subjects of experience, and that these beliefs are justified independently of any reductionist analysis of what it means to be a person. This has two important implications that are relevant to the ongoing debate concerning the number of persons that are in existence throughout any duration in time: (...) (1) the lack of logically or metaphysically necessary and sufficient conditions for distinguishing one person from another should imply neither that there is only one person nor that personhood is not individuative; and (2) the lack of such universally applicable identity criteria should not imply that the term ‘person’ is a folk term with no real application. In other words, lack of reductionist analysis does not entail lack of existence. (shrink)

This paper examines the prevalent assumption that when people interact online via proxies—avatars—they encounter each other. Through an exploration of the ontology of users and their avatars we argue that, contrary to the trend within current discussions of interaction online, this cannot be unproblematically assumed. If users could be considered in some sense identical to their avatars, then it would be clear how an encounter with an avatar could ground an encounter with another user. We therefore engage in a systematic (...) investigation of several conceptions of identity, concluding that in none of these senses can users and avatars be identified. We go on to explore how current accounts of identity-as-selfhood online might resolve this problem by appealing to narrativity or authorship, ultimately concluding that as these accounts stand they are unable to provide grounds for the claim that users encounter each other online and so supplementary work is required.

How does the modern scientific conception of time constrain the project of assigning the mind its proper place in nature? On the scientific conception, it makes no sense to speak of the duration of a pain, or the simultaneity of sensations occurring in different parts of the brain. Such considerations led Henri Poincaré, one of the founders of the modern conception, to conclude that consciousness does not exist in spacetime, but serves as the basic material out of which we must (...) create the physical world. The central claim of Sensorama is that Poincaré was substantially correct. The best way to reconcile the scientific conception of time with the evidence of introspection is through a phenomenalist metaphysic according to which consciousness exists in neither time nor space, but serves as a basis for the logical construction of spacetime and its contents.
