Both Marya Schechtman and Galen Strawson appeal to autobiographical memory in developing their accounts of personal identity. Although both scholars share a similar conception of autobiographical memory, they use it to develop theories of personal identity that are radically distinct. Memories that are relevant for personal identity are generally considered to be personal (autobiographical) memories of those events in one’s lifetime to which one can gain first-personal access: memories from-the-inside. Both Schechtman and Strawson base their discussion of personal identity on (...) exactly this type of memory. Empirical evidence shows, however, that personal memory imagery is not only visualised from-the-inside, from a “field” perspective. Personal memories may also involve “observer” perspectives, in which one sees oneself from-the-outside in the remembered scene. Both Schechtman and Strawson appeal to the notion of remembering from-the-inside, but they remain silent on the phenomenon of observer perspectives in personal memory. I suggest that accounts of personal identity that appeal to memory should consider observer perspectives as one aspect of personal memory. I explore the implications that the acknowledgment and inclusion of observer perspectives would have for both Schechtman’s and Strawson’s accounts. Even though autobiographical memory is not their theoretical target, both Schechtman and Strawson base their accounts of personal identity on their understanding of autobiographical memory. Therefore, their depictions of the nature of personal identity are founded upon an incomplete picture of autobiographical memory. (shrink)

What does our naïve conception of a conscious subject demand of the nature of conscious beings? In a series of recent papers David Barnett has argued that a range of powerful intuitions in the philosophy of mind are best explained by the hypothesis that our naïve conception imposes a requirement of mereological simplicity on the nature of conscious beings. It is argued here that there is a much more plausible explanation of the intuitions in question. Our naïve conception of a (...) conscious subject imposes a requirement of topological integrity.

Contemporary philosophers of mind tend to accept either some version of dualism or physicalism when considering the mind–body problem. Likewise, recent philosophers of religion typically assume that we must work within these two categories when considering problems related to the possibility of bodily resurrection. Recently, some philosophers have reintroduced the Thomistic version of hylomorphism. In this article, we will consider the distinctive doctrines of Thomistic hylomorphism and how they can be used to address concerns about both the mind–body problem and (...) the possibility of resurrection. We will see that hylomorphism allows for a novel version of emergent property dualism that is both metaphysically plausible and allows us to recognize the irreducibility of mental states and the possibility of resurrection without ignoring the fact of human embodiment. We will also discuss the currently lively debate among Thomistic hylomorphists who advocate opposed corruptionist and survivalist versions of the afterlife. (shrink)

What sort of thing, fundamentally, are you and I? For convenience, I use the term persimal to refer to the kind of thing we are, whatever that kind turns out to be. Accordingly, the question is, what are persimals? One possible answer is that persimalhood consists in being a human animal, but many theorists, including Derek Parfit and Jeff McMahan, not to mention John Locke, reject this idea in favor of a radically different view, according to which persimalhood consists in (...) having certain sorts of mental or psychological features. In this essay, I try to show that the animalist approach is defensible as against the mentalist approach. I also suggest that animalists have a plausible story to tell about cases such as brain transplantation and dicephaly that might appear to support the mentalist approach. (shrink)

Some Christian materialists have argued for the possibility of resurrection given that persons are constituted by bodies, and constitution is not identity. Baker's constitutionist view claims superiority over animalist alternatives but offers only circular accounts of both personal identity over time and personhood. Corcoran's alternative approaches these questions differently but makes use of Zimmerman's ‘Falling Elevator Model’ of resurrection, which is rendered incoherent by its reliance on contingent identity. A recent constitutionist revision of this model succeeds only in exchanging incoherence (...) for absurdity. Despite difficulties for such resurrection accounts, the idea of constitution as a sui generis relation remains attractive among philosophers and Christian materialists in particular. However, Wasserman's deflationary view combines with problems such as extensionality, indiscernibility and the explosion of reality to provide reason to worry that constitution might be just identity after all. If so, then the metaphysics of constitution cannot provide a convenient route between animalism and immaterialism when explaining the possibility of resurrection. (shrink)

Whether or not it is coherent to place hope in a future life beyond the grave has become a central question in the larger debate about whether a materialist view of human persons can accommodate Christian belief. Hud Hudson defends a four-dimensional account of resurrection in order to avoid persistent difficulties experienced by three-dimensionalist animalism. I present two difficulties unique to Hudson’s view. The first problem of counterpart hope is a manifestation of a general weakness of four-dimensional views to accommodate (...) adequately prudential concern about one’s future self. More significantly, the second problem of quasi hope demonstrates that even if a temporal parts view can accommodate the possibility of future resurrection it necessarily leaves human beings in the dark about their individual futures and thus incapable of hope. I conclude that whatever its merits in demonstrating the possibility of resurrection, four-dimensionalist materialism cannot accommodate veridical Christian hope. (shrink)

The goal of this paper is to defend animalism from the remnant person problem. Specifically, I argue that animalism is consistent with the view that one could become a remnant person in virtue of psychological continuity. For this argument, I show that the dilemma for the remnant person parallels the dilemma animalists use when they argue that one could become a human vegetable or corpse. I then argue that animalists who claim that psychological continuity is not necessary for our persistence (...) through time should say that biological continuity is not necessary either. This implies that psychological continuity is sufficient, though not necessary, for personal identity over time in some cases. Finally, I show how my argument points animalists toward anti-criterialism and defend it from a fission problem. (shrink)

The central argument for animalism is the thinking animal problem : if you are not an animal, there are two thinkers within the region you occupy, i.e., you and your animal body. This is absurd. So you are an animal. The main objection to this argument is the thinking brain problem : animalism faces a problem that is structurally analogous to TAP. Specifically, if animalism is true, you and your brain both think. This is absurd. So animalism is false. The (...) purpose of this paper is to propose strategies animalists can endorse to solve TBP. I first show that animalists can solve TBP by arguing that it is not sound. This solution to TBP raises questions about personal identity over time and the mereological relation between the person and the brain. I argue that animalists can answer the personal identity question by endorsing non-biological persistence conditions as well as biological ones. For the mereological question, I first show that animalism is incompatible with four-dimensionalism and eliminativism. I then argue that animalists should endorse the dominant sortal account to answer the mereological question. (shrink)

Physicalist Christology is the view that God the Son, in the Incarnation, became identical with the body of Jesus. The goal of this paper is to defend PC from two recent objections. One is that if GS is a physical object, then he cannot have properties had by God. Then, by Leibniz’s law, the incarnate GS cannot be identical with the second Person of the Trinity. The other objection is that PC implies that the incarnate GS did not exist in (...) the interim period between his death and resurrection. PC then leads to the theologically absurd consequence that one of the three Persons of the Trinity did not exist during this period. I argue that the first objection fails because the very same argumentative strategy applies to the Incarnation on any view. As for the second objection, I endorse an animalist theory of death and argue that the incarnate GS continues to exist as a dead person from his death to resurrection. This shows that there is still continuing Trinity of GS during this period. (shrink)

The determination of death by neurological criteria (brain death) is practiced in at least 80 countries, though it is a matter of continuing controversy. At the same time, the brain is central to human life, thinking, and behavior; however, a growing “neurocentrism” or a brain‐focused image of human identity became established in most Western and in many non‐Western societies and acts as a forceful ideology. This paper seeks a broader theoretical and sociocultural basis to approaching death bioethically by analyzing criticisms (...) aimed at a neurologically focussed vision of human life, and then turning these towards the brain death criteria exposed to the criticism. The overall critique of the “neuro‐self” has scope to offer alternative perspectives to the contested issues in brain‐death criteria. Specifically, the paper examines two major shortcomings of a narrow brain view of life and culture. First, it considers the reduction of the individual to the brain: this is the crux of the neurological way of determining death, and is a way that is seemingly context‐independent and culturally neutral. Second, it considers how dimensions of society and culture for humans are detached from the brain and have little impact on clinical practice and thinking in brain‐death criteria; however, a deeper exploration reveals that they actually have direct relevance and that social and cultural factors have greater contributions to make to the current debates.

Trenton Merricks has argued that given endurantism personal identity is unanalysable in terms of psychological continuity, while Anthony Brueckner has argued against this claim. This article shows that neither philosopher has made a compelling case and also shows what it would take to settle the issue either way. It is then argued that whether personal identity is analysable or not may not be of crucial importance to those wanting to defend a psychological continuity approach to personal identity.

Sartre's conception of bad faith suggests that every desire to be someone in love is self-deceptive in the attempt to define my factual being. Departing from İlham Dilman's discussion of personal identity, I argue that this view on selfhood is inattentive to the kind of personal and moral reflection inherent in asking who I am. There is a temptation in love to deceive myself and you by renouncing responsibility. Yet the concept also embodies demands that allow me to continuously shape (...) myself into a loving subject by scrutinising my responses and by asking whether they are expressive of love or not.

The Problem of Overlappers is a puzzle about what makes it the case, and how we can know, that we have the parts we intuitively think we have. In this paper, I develop and motivate an overlooked solution to this puzzle. According to what I call the self-making view it is within our power to decide what we refer to with the personal pronoun ‘I’, so the truth of most of our beliefs about our parts is ensured by the very (...) mechanism of self-reference. Other than providing an elegant solution to the Problem of Overlappers, the view can be motivated on independent grounds. It also has wide-ranging consequences for how we should be thinking about persons. Among other things, it can help undermine an influential line of argument against the permissibility of elective amputation. After a detailed discussion and defence of the self-making view, I consider some objections to it. I conclude that none of these objections is persuasive and we should at the very least take seriously the idea that we are to some extent self-made. (shrink)

Nihilism is the thesis that no composite objects exist. Some ontologists have advocated abandoning nihilism in favor of deep nihilism, the thesis that composites do not existO, where to existO is to be in the domain of the most fundamental quantifier. By shifting from an existential to an existentialO thesis, the deep nihilist seems to secure all the benefits of a composite-free ontology without running afoul of ordinary belief in the existence of composites. I argue that, while there are well-known (...) reasons for accepting nihilism, there appears to be no reason at all to accept deep nihilism. In particular, deep nihilism draws no support either from the usual arguments for nihilism or from considerations of parsimony. (shrink)

In this paper, I first consider a famous objection that the standard interpretation of the Lockean account of diachronicity (i.e., one’s sense of personal identity over time) via psychological connectedness falls prey to breaks in one’s personal narrative. I argue that recent case studies show that while this critique may hold with regard to some long-term autobiographical self-knowledge (e.g., episodic memory), it carries less warrant with respect to accounts based on trait-relevant, semantic self-knowledge. The second issue I address concerns the (...) question of diachronicity from the vantage point that there are (at least) two aspects of self—the self of psychophysical instantiation (what I term the epistemological self) and the self of first person subjectivity (what I term the ontological self; for discussion, see Klein SB, The self and its brain, Social Cognition, 30, 474–518, 2012). Each is held to be a necessary component of selfhood, and, in interaction, they are appear jointly sufficient for a synchronic sense of self (Klein SB, The self and its brain, Social Cognition, 30, 474–518, 2012). As pertains to diachronicity, by contrast, I contend that while the epistemological self, by itself, is precariously situated to do the work required by a coherent theory of personal identity across time, the ontological self may be better positioned to take up the challenge.

Current formulations of Four-Dimensionalism may be objected to on grounds that they are too inflexible: the formulations do not seem to allow for enough variety in the views they are paired with. For instance, Kit Fine has noted that formulations of Four-Dimensionalism in terms of instantaneous parts may be too demanding for Four-Dimensionalists who believe nothing is instantaneous. And Trenton Merricks has argued that one can think something persists four-dimensionionally without taking it to have proper temporal parts, and claims that (...) our formulation of Four-Dimensionalism should be revised to allow for this. I will add my own worries to those of Fine and Merricks. I will note that current formulations of Four-Dimensionalism are not sufficiently neutral with respect to the structure of time, with respect to how liberally objects decompose into parts, and with respect to whether objects and the regions they fill match in mereological structure. I will show that we can formulate Four-Dimensionalism in a sufficiently neutral way, while still producing a view that can do the work we typically require of Four-Dimensionalism. (shrink)

What is the metaphysical relationship between the fetus/embryo and the pregnant organism? In this paper I apply a substance metaphysics view developed by Barry Smith and Berit Brogaard to argue, on the basis of topological connectedness, that fetuses/embryos are Lady-Parts: part of the maternal organism up until birth. This leaves two options. Either mammalian organisms begin at birth, or we revise our conception of organisms such that mammalian organisms can be part of other mammals. The first option has some advantages: (...) it is numerically neat; aligns with an intuitive picture of organisms as physically distinct individuals; and ties ‘coming into existence’ to a suitably recognisable and important event: birth. But it denies that the fetus survives birth, or that human organisms existed prior to their birth. The second option allows us to recognise that human organisms exist prior to and survive their birth, but at a cost: it leaves the question of when an organism comes into existence unanswered, and demands potentially far-reaching conceptual revision across a range of domains.

Scott Campbell has recently defended the psychological approach to personal identity over time by arguing that a person is literally a series of mental events. Rejecting four-dimensionalism about the persistence of physical objects, Campbell regards constitutionalism as the main rival version of the psychological approach. He argues that his "series view" has two clear advantages over constitutionalism: it avoids the "two thinkers" objection and it allows a person to change bodies. In addition, Campbell suggests a reply to the objection, often (...) raised against views such as his, that thoughts must be distinct from their thinker. In this paper, I argue that Campbell's responses to the "two thinkers" and the "thoughts/thinker" objections are unsuccessful. Furthermore, his reply to the latter leads to four-dimensionalism of the kind he wanted to avoid – and this view too allows a person to change bodies. Moreover, I argue that it speaks against the series view that generalised versions of it fare much more poorly than do generalised versions of constitutionalism and four-dimensionalism. (shrink)

Psychiatric patients sometimes ask where to draw the line between who they are – their selves – and their mental illness. This problem is referred to as the self-illness ambiguity in the literature; it has been argued that solving said ambiguity is a crucial part of psychiatric treatment. I distinguish a Realist Solution from a Constructivist one. The former requires finding a supposedly pre-existing border, in the psychiatric patient’s mental life, between that which belongs to the self and that which (...) belongs to the mental illness. I argue that no such border exists, and that attempts to find it might even render the felt ambiguity worse. Instead, any solution must be constructivist; the patient (and others) should deliberate and discuss what to identify with or not. I further argue that psychiatric patients need not see their mental illness as wholly distinct from themselves to avoid ‘identifying with their diagnoses' in a problematic way. Finally, we can excuse problematic behaviour by mentally ill people – in fact, we can do so in a more nuanced and constructive way – while rejecting the view that the mental illness is wholly distinct from the patient’s self.

In this paper we articulate and diagnose a previously unrecognized problem for theories of entitlement, what we call the Claims Conundrum. It applies to all entitlements that are originally generated by some claim-generating action, such as laboring, promising, or contract-signing. The Conundrum is spurred by the very plausible thought that a later claim to the object to which one is entitled is a function of whether that original claim-generating action is attributable to one. This is further assumed to depend on (...) one’s being identical to the person who performed the claim-generating action. But the right theory of personal identity for grounding these later claims proves quite elusive. In demonstrating both the Claims Conundrum and diagnosing its source, we begin with its instantiation in John Locke’s theories of personal identity and initial acquisition, and then we gradually expand its net to include both Lockean and non-Lockean theories of both, moving ultimately to show that this is a problem for most entitlements generally. We then diagnose the source of the trouble, showing that a basic assumption about the link between attributability and identity that most people take to be obvious is in fact false, clearing a path for future investigation into this overlooked but serious problem’s resolution.

According to the cohabitation account, all the persons that result from a fission event cohabit the same body prior to fission. This article concerns a problem for this account. Suppose Manuel and Jimena are suffering from an equally painful migraine. Unlike Jimena, however, Manuel will undergo fission. Assuming you have a spare painkiller, whom should you give it to? Intuitively, you have no more reason to give it to one or the other. The problem is that the cohabitation account suggests (...) otherwise. According to the account, there are two persons cohabiting Manuel’s body, in which case you should arguably give them the pill, since doing so alleviates the pain of more beings. One response argues that the two persons cohabiting Manuel’s body share one pain. Thus, giving them the pill alleviates no more pain than giving it to Jimena, and therefore you have no more reason to do one or the other. The goal of this article is to show that this response fails. (shrink)

Plans to attempt what has been called a head transplant, a body transplant, and a head-to-body transplant in human beings raise numerous ethical, social, and legal questions, including the circumstances, if any, under which it would be ethically permissible to attempt whole-body transplantation (WBT) in human beings, the possible effect of WBT on family relationships, and how families should shape WBT decisions. Our assessment of many of these questions depends partially on how we respond to sometimes centuries-old philosophical thought experiments (...) about personal identity. As with so much in bioethics, it is impossible to escape, or at least inadvisable to try to bypass, the relevant foundational philosophical concerns. (shrink)

Psychological accounts of personal identity claim that the human person is not identical to the human animal. Advocates of such accounts maintain that the definition and criterion of death for a human person should differ from the definition and criterion of death for a human animal. My contention is instead that psychological accounts of personal identity should have human persons dying deaths that are defined biologically, just like the deaths of human animals. Moreover, if brain death is the correct criterion (...) for the death of a human animal, then it is also the correct criterion for the death of a human person. What the nonidentity of persons and animals requires is only that they have distinct criteria for ceasing to exist. (shrink)

There remains a need to properly analyze the metaphysical assumptions underlying two organ procurement policies: presumed consent and organ sales. Our contention is that if one correctly understands the metaphysics of both the human body and material property, then it will turn out that while organ sales are illiberal, presumed consent is not.

Animalism is prima facie the most plausible view about what we are; it aligns better with science and common sense, and is metaphysically more parsimonious. Thought experiments involving the brain, however, tend to elicit intuitions contrary to animalism. In this paper, I examine two classical thought experiments from the literature, brain transplant and cerebrum transplant, and a new one, cerebrum regeneration. I argue that they are theoretically possible, but that a scientifically informed account of what would actually happen shows that (...) in none of the cases would the person be separated from the animal. Our intuitions in these cases, when adequately informed by neuroscience, do not conflict with animalism – rather, they suggest a correction of the animalist position: the persisting animal should be at least minimally sentient. Sentience animalism is a new formulation of the animalist account of personal identity that allows us to reconcile facts about our biological persistence conditions with the intuition that human persistence should involve some kind of psychological continuity.

Animalism offers a more attractive account of the human person than the Embodied Mind Account. If people are not animals, but small proper parts of animals, then there is a threat of spatially coincident thinkers. This will likely have to be avoided at the cost of the sparsest of ontologies, one in which there are no larger entities that can become reduced to the size of the brain or cerebrum-size thinker. This will be a rather implausible ontology as such thinkers (...) will not fit well into the natural world, meet traditional independence or unity criteria for being substances, nor provide a compositional principle with causal glue.

ABSTRACT: There are some problems with Lynne Baker’s constitution account of personal identity that become evident when we consider brain transplant thought experiments and two kinds of rare cases of conjoined twins — the first appears to be one organism but two persons and the second seems to involve two organisms associated with one person. To handle the problems arising from brain transplants, the constitution theorist must admit an additional level of constitution between the organism and the person. To resolve (...) the problems posed by the two kinds of conjoined twins, the constitution theorist must accept that constitution is not always a one-to-one relationship. RESUME: La théorie constitutionnelle de l’identité personnelle de Lynne Baker soulève certains problèmes qui deviennent évidents lorsque l’on considère des expériences de pensée sur des transplantations de cerveaux et deux genres de cas rares de jumeaux conjoints — du premier cas paraît s’ensuivre qu’il y a deux personnes pour un seul organisme alors que du deuxième découle qu’une seule personne existe dans deux organismes. Afin d’expliquer les problèmes qui surviennent avec les transplantations de cerveaux, le théoricien de la constitution doit admettre un niveau de constitution intermédiaire entre l’organisme et la personne. Pour résoudre les problèmes que posent les cas de jumeaux conjoints, le théoricien de la constitution doit accepter que la relation de constitution ne se réalise pas toujours entre deux termes.

Eric Olson criticizes Lynne Baker’s constitution account of persons on the grounds that personhood couldn’t be ontologically significant as nothing new comes into existence with the acquisition of thought. He claims that for something coming to function as a thinker is no more ontologically significant than something coming to function as a locomotor when a motor is added to it. He levels two related charges that there’s no principled answer about when and where constitution takes place rather than an already (...) existing object just acquiring new properties. I’ll argue that none of these objections are problems for understanding person to be a substantial kind. (shrink)

We argue that animalism is the only materialist account of personal identity that can account for the autonomy that we typically think of ourselves as possessing. All the rival materialist theories suffer from a moral version of the problem of too many thinkers when they posit a human person that overlaps a numerically distinct human animal. The different persistence conditions of overlapping thinkers will lead them to have interests that conflict, which in many cases prevents them both from autonomously forming (...) and acting on the same intentions. These problems are exacerbated by problems of self-reference plaguing the overlapping thinkers. We contend that the impossibility of simultaneous autonomous action by animals and persons provides a reason to favor animalism over Neo-Lockeanism, Four-Dimensionalism, Constitution theory, and brain-size views of the person. We anticipate and reject arguments that the autonomy of the person and the animal can be shown to be compatible by relying upon either the Parfitian thesis that identity isn’t what matters or claiming that animals acquire the interests of the person they constitute.

A number of philosophers maintain that the destruction of an embryo in the first 2 weeks after fertilization is not morally problematic as it is metaphysically impossible for any human organism to then have existed. We contend that the typical adult human organism was once a zygote so there is no metaphysical shortcut to justify early abortion. We show that five arguments against human organisms ever having been zygotes fail. All of the arguments have to do with one variant or (...) another of the zygote or early embryo dividing. They do not provide any reason to believe that since some adult organisms are not identical to zygotes due to earlier divisions, none could have been. (shrink)

The defensibility of the extended mind thesis (EMT) is often thought to hinge on the possibility of extended selves. I argue that the self cannot extend and consider the ramifications of this finding, especially for EMT. After an overview of EMT and the supposed cruciality of the extended self to the defensibility of the former thesis, I outline several lines of argument in support of the possibility of extended selves. Each line of argument appeals to a different account of diachronic (...) personal identity. I argue that no such argument for extended selves succeeds, as no account of diachronic personal identity is both plausible and supports the view that the self can extend. Next, I consider three objections that, if successful, would undercut the preceding argument that the self cannot extend. I conclude by reflecting on the implications of the conclusion that the self cannot extend, including the prospects for EMT. (shrink)

There are three families of solutions to the traditional Amputation Paradox: Eliminativism, Contingent Identity Theories, and Theories of Coincident Entities. Theories of Coincident Entities challenge our common understanding of the relation between identity and parthood, since they accept that two things can be mereologically coincident without being identical. The contemporary discussion of the Amputation Paradox tends to mention only one theory of Coincident Entities, namely the Constitution View, which violates the mereological principle of Extensionality. But in fact, there is another (...) theory, namely the Unique Part View, which violates another mereological principle. In this paper, I argue that the contemporary focus on the Constitution View is unmotivated, at least when we are confronted with the Amputation Paradox, and that a balanced comparison of the two views should favour the Unique Part View.

In the debate on personal identity, different criteria of identity are proposed and defended. The criteria of identity have usually been taken to state the necessary and sufficient conditions of identity and are interpreted as providing truth conditions for relevant identity statements. The Simple View of personal identity is the thesis that there are no noncircular and informative metaphysical criteria of identity for persons. The paper intends to first deliver a precise and general formulation of the Simple View, and, second, (...) to present the various arguments in favour of the doctrine in question. It argues that there are no other facts of the matter than identity itself which could serve as the truth-conditions of identity statements. The considerations presented in the paper lead to the conclusion that, although the Simple View is faced with many theoretical difficulties, it is still a lively intellectual position in the debate on personal identity.

This paper investigates the notion of ‘distributed cognition’—the idea that entities external to one’s organic brain participate in one’s overall cognitive functioning—and the challenges it poses to the notion of personhood. Related to this is also a consideration of the ever-increasing ways in which neuroprostheses replace and functionally replicate organic parts of the brain. However, the literature surrounding such issues has tended to take an almost exclusively physicalist approach. The common assumption is that, given that non-physicalist theories (chiefly, dualism, and (...) hylomorphism) postulate some form of immaterial ‘soul’, then they are immune from the challenges that these advances in cognitive science pose. The first aim of this paper, therefore, is to argue that this is not the case. The second aim of this paper is to attempt to elucidate a route available for the non-physicalists that will allow them to accept the notion of distributed cognition. By appealing to an Aristotelian framework, I propose that the non-physicalist can accept the notion of distributed cognition by appealing to the notion of ‘unitary life’ which I introduce, as well as to Aristotle’s dichotomy between active and passive mind.

I am a person. But am I fundamentally and essentially a person? The animalist says no. So must the phenomenal continuity theorist, or so I will argue. Even if, contra animalism, we cannot survive zombification, being a subject of experience is not sufficient for being a person, and phenomenal continuity is not sufficient for our survival as the same person over time. These observations point the way to a positive account of personhood, and provide further insight into the conditions under (...) which literal survival preserves what matters. (shrink)

Abstract. Could a person or mind be uploaded—transmitted to a computer or network—and thereby survive bodily death? I argue ‘mind uploading’ is possible only if a mind is an abstract object rather than a concrete particular. Two implications are notable. One, if someone can be uploaded someone can be multiply-instantiated, such that there could be as many instances of a person as copies of a book. Second, mind uploading’s possibility is incompatible with the leading theories of personal identity, insofar as (...) these assume the mind is a concrete particular. Moreover, because David Chalmers (2010; 2012; 2014) defends mind uploading without construing minds as abstract, I show Chalmers’ argument to be unsound. (shrink)

The neuroscience revolution has led many scientists to posit “expansive” or “thinking” brains that instantiate rich psychological properties. As a result, some scientists now even claim you are identical to such a brain. However, Eric Olson has offered new arguments that thinking brains cannot exist due to their intuitively “abominable” implications. After situating the commitment to thinking brains in the wider scientific discussions in which they are posited, I then critically assess Olson's arguments against such entities. Although highlighting an important (...) insight, I show that Olson's objections to the existence of thinking brains fail and that a wider discussion engaging our new empirical findings is actually required in order to resolve the deeper issues.

Various psychopathologies of self-awareness, such as somatoparaphrenia and thought insertion in schizophrenia, might seem to threaten the viability of the higher-order thought (HOT) theory of consciousness since it requires a HOT about one’s own mental state to accompany every conscious state. The HOT theory of consciousness says that what makes a mental state a conscious mental state is that there is a HOT to the effect that “I am in mental state M.” I have argued in previous work that a (...) HOT theorist can adequately respond to this concern with respect to somatoparaphrenia and thought insertion. There is also Cotard syndrome which is a rare neuropsychiatric disorder in which people hold the delusional belief that they are dead, do not exist, or have lost their blood or internal organs. In this paper, I argue that HOT theory has nothing to fear from it either and can consistently account for what happens in such unusual cases. I analyze Cotard syndrome in light of my previous discussion of somatoparaphrenia and thought insertion, and argue that HOT theory can provide a somewhat analogous account without the worry of inconsistency. It is crucial to recognize that there are multiple “self-concepts” and levels of HOTs which can help to provide a more nuanced explanation. With regard to the connection between consciousness and self-consciousness, it is proposed that Cotard patients are indeed capable of having some “I-thoughts” about their bodies and mental states.

Various cases of conjoined twinning have been presented as problems for the animalist view that we are animals. In some actual and possible cases of human dicephalus that have been discussed in the literature, it is arguable that there are two persons but only one human animal. It is also tempting to believe that there are two persons and one animal in possible instances of craniopagus parasiticus that have been described. Here it is argued that the animalist can admit that (...) these are cases in which human persons are not animals, without forfeiting the title “animalist.” It is also shown that this is not only an option but also a well-motivated and plausible option for the animalist. Seeing this requires getting clear on what the word “we” should be thought to include in the animalist's claim that we are animals. Here animalism is defended against twinning objections by figuring out how to view the scope of the animalist's identity claim. (shrink)

Nearly all defences of the agent-causal theory of free will portray the theory as a distinctively libertarian one — a theory that only libertarians have reason to accept. According to what I call ‘the standard argument for the agent-causal theory of free will’, the reason to embrace agent-causal libertarianism is that libertarians can solve the problem of enhanced control only if they furnish agents with the agent-causal power. In this way it is assumed that there is only reason to accept (...) the agent-causal theory if there is reason to accept libertarianism. I aim to refute this claim. I will argue that the reasons we have for endorsing the agent-causal theory of free will are nonpartisan. The real reason for going agent-causal has nothing to do with determinism or indeterminism, but rather with avoiding reductionism about agency and the self. As we will see, if there is reason for libertarians to accept the agent-causal theory, there is just as much reason for compatibilists to accept it. It is in this sense that I contend that if anyone should be an agent-causalist, then everyone should be an agent-causalist. (shrink)

According to reductionists about agency, an agent’s bringing something about is reducible to states and events involving the agent bringing something about. Many have worried that reductionism cannot accommodate robust forms of agency, such as self-determination. One common reductionist answer to this worry contends that self-determining agents are identified with certain states and events, and so these states and events causing a decision counts as the agent’s self-determining the decision. In this paper, I discuss Michael Bratman’s well-known identification reductionist theory (...) and his general strategy of grounding an agent’s identification at a time in the agent’s identity over time. I develop two constraints that an adequate identification reductionist theory must satisfy, argue that Bratman’s theory cannot satisfy both, and show that his general strategy for grounding an agent’s identification at a time in the agent’s identity over time is without merit.

Consider the following two metaphysical questions about pregnancy: (1) When does a new organism of a certain kind start to exist? (2) What is the mereological and topological relationship between the pregnant organism and with what it is pregnant? Despite assumptions made in the literature, I take these questions to be independent of each other, such that an answer to one does not provide an answer to the other. I argue that the way to connect them is via a maximality (...) principle that prevents one organism being a proper part of another organism of the same kind. That being said, such a maximality principle need not be held, and may not apply in the case of pregnancy. The aims of this paper are thus to distinguish and connect these metaphysical questions, in order to outline a taxonomy of rival mereotopological models of pregnancy that result from the various combinations of their answers.

If a lump of clay is shaped into a statue, is there one thing or are there two? That is: are the lump and the statue two distinct things? This dialogue introduces some reasons to think they are two different things and then discusses the issues involved.

Transhumanism is an ideology that embraces the use of various forms of biotechnology to enhance human beings toward the emergence of a “posthuman” kind. In this article, I contrast some of the foundational tenets of Transhumanism with those of Christianity, primarily focusing on their respective anthropologies—that is, their diverse understandings of whether there is an essential nature shared by all human persons and, if so, whether certain features of human nature may be intentionally altered in ways that contribute toward how (...) each views human flourishing. A central point of difference concerns Transhumanists’ aim of attaining “substrate independence” for the human mind, such that one’s consciousness could be uploaded into a cybernetic environment. Christian anthropology, on the other hand, considers embodiment, with its characteristics of vulnerability and finitude, to be an essential feature of human nature—hence, Christians’ belief in bodily resurrection. Despite Christianity and Transhumanism having fundamental differences, I contend that Christians may support moderate forms of enhancement oriented toward supporting our flourishing as living, sentient, social, and rational animals.

I can be aware of myself, and thereby come to know things about myself, in a variety of different ways. But is there some special way in which I—and only I—can learn about myself? Can I become aware of myself by introspecting? Do I somehow show up in my own conscious experiences? David Hume and most contemporary philosophers say no. They deny that the self shows up in experience. However, in this paper I appeal to research on schizophrenia—on thought insertion, (...) in particular—to argue that Hume and his follows are wrong: The self does, in fact, show up in experience.

Suppose that you're lying in bed. You just woke up. But you're alert. Your mind is clear and you have no distractions. As you lie there, you think to yourself, ‘2 + 2 = 4.’ The thought just pops into your head. But, wanting to be sure of your mathematical insight, you once again think ‘2 + 2 = 4’, this time really meditating on your thought. Now suppose that you're sitting in an empty movie theatre. The lighting is normal (...) and the screen in front of you is blank. Then at some point an image of a peach is flashed on the screen. The image isn't up there for long. In fact, it's only on the screen for what seems like an instant—just long enough for you to see it. These two scenarios are a bit mundane. But, as I will show, reflection on them can yield significant results concerning the nature of persons and their persistence through time. First I will show that thought and perception have temporal constraints whereby your thinking or perceiving in the above scenarios implies that you exist through a temporally.. (shrink)
