Many philosophers have become sceptical of the use of thought experiments in theorising about personal identity. In large part this is due to work in experimental philosophy that appears to confirm long held philosophical suspicions that thought experiments elicit inconsistent judgements about personal identity, and hence judgements that are thought to be the product of cognitive biases. If so, these judgements appear to be useless at informing our theories of personal (...) identity. Using the methods of experimental philosophy, we investigate whether people exhibit inconsistent judgements and, if they do, whether these judgements are likely to be the source of cognitive bias or, instead, sensitivity to some relevant factor. We do not find that people’s judgements are sensitive to any of the factors we investigate (relevant or irrelevant), nor that people have inconsistent judgements across cases. Rather, people’s judgements are best explained by them having a very minimal account of what it takes for a person to survive. Since this pattern of judgements is no reason to think that we are subject to cognitive bias, we see no reason, as things stand, to be sceptical of our judgements. (shrink)

Should we descry the nature of the self from thought experiments? Shaun Nichols says ‘maybe,’ but only if we use thought experiments that do not recruit the indexical “I” (non-I-recruiting). His reason is that the psychology of “I” perforce mandates that imagination responds to thought experiments that recruit it (I-recruiting) peculiarly. Here, I consider whether he is correct about non-I-recruiting personal identity thought experiments. I argue positively using the same framework, (...) i.e., considering the underlying psychology.

Good physical experiments conform to the basic methodological standards of experimental design: they are objective, reliable, and valid. But is this also true of thought experiments? Especially problems of personal identity have engendered hypothetical scenarios that are very distant from the actual world. These imagined situations have been conspicuously ineffective at resolving conflicting intuitions and deciding between the different accounts of personal identity. Using prominent examples from the literature, I argue that this is (...) due to many of these thought experiments not adhering to the methodological standards that guide experimental design in nearly all other disciplines. I also show how empirically unwarranted background assumptions about human physiology render some of the hypothetical scenarios that are employed in the debate about personal identity highly misleading.

Thought experiments are profitably compared to compasses. A compass is a simple but useful device for determining direction. Nevertheless, it systematically errs in the presence of magnets ...it becomes unreliable near the North Pole, in mine shafts, when vibrated, in the presence of metal ...experts will wish to use the compass as one element in a wider portfolio of navigational techniques. Analogously, thought experiments are simple but useful devices for determining the status of propositions. Sadly, they (...) systematically err under certain conditions and so are best used with sensitivity to their foibles and limited scope (Sorensen, 1992, pp. 288–289). (shrink)

This book explores the scope and limits of the concept of personDS a vexed question in contemporary philosophy. The author begins by questioning the methodology of thought-experimentation, arguing that it engenders inconclusive and unconvincing results, and that truth is stranger than fiction. She then examines an assortment of real-life conditions, including infancy, insanity andx dementia, dissociated states, and split brains. The popular faith in continuity of consciousness, and the unity of the person is subjected to sustained criticism. The author (...) concludes with a look at different views of the person found in Homer, Aristotle, the post-Cartesians, and contemporary cognitive science. (shrink)

African perspectives on personhood and personal identity and their relation to those of the West have become far more central in mainstream Western discussion than they once were. Not only are African traditional views with their emphasis on the importance of community and social relations more widely discussed, but that emphasis has also received much wider acceptance and gained more influence among Western philosophers. Despite this convergence, there is at least one striking way in which the discussions remain (...) apart and that is on a point of method. The Western discussion makes widespread use of thought experiments. In the African discussion, they are almost entirely absent. In this article, we put forward a possible explanation for the method of thought experiment being avoided that is based on considerations stemming from John Mbiti’s account of the traditional African view of time. These considerations find an echo in criticism offered of the method in the Western debate. We consider whether a response to both trains of thought can be found that can further bring the Western and African philosophical traditions into fruitful dialogue. (shrink)

In a recent series of papers, Beck and Wagner have been arguing about the general role that thought experiments can play in the debate on personal identity, showing their disagreement about the famous criticisms that Wilkes’ launched against their use. In this article I come back to Wilkes’ criticisms to show that her position is deeply problematic. If we adopt instead the mental model account of thought experiments, we can accommodate Wilkes’ criticisms and justify (...) the use of thought experiments in the debate of personal identity. This will allow us to see why Beck and Wagner were both half right and half wrong in their discussion. (shrink)

Through careful analysis of a specific example, Parfit’s ‘fission argument’ for the unimportance of personal identity, I argue that our judgements concerning imaginary scenarios are likely to be unreliable when the scenarios involve disruptions of certain contingent correlations. Parfit’s argument depends on our hypothesizing away a number of facts which play a central role in our understanding and employment of the very concept under investigation; as a result, it fails to establish what Parfit claims, namely, that identity (...) is not what matters. I argue that Parfit’s conclusion can be blocked without denying that he has presented an imaginary case where prudential concern would be rational in the absence of identity. My analysis depends on the recognition that the features that explain or justify a relation may be distinct from the features that underpin it as necessary conditions. (shrink)

Paul Ricoeur and Marya Schechtman express grave doubts about the acceptability and informativeness of the thought-experiments employed by analytic philosophers (notably Derek Parfit) in the debate about personal identity, and for what appear to be related reasons.

Hylomorphism offers a third way between animalist approaches to personal identity, which maintain that psychology is irrelevant to our persistence, andneo-Lockean accounts, which deny that humans are animals. This paper provides a Thomistic account that explains the intuitive responses to thought experiments involving brain transplants and the transformation of organic bodies into inorganic ones. This account does not have to follow the animalist in abandoning the claim that it is our identity which matters in survival, (...) or countenance the puzzles of spatially coincident entities that plague the neo-Lockean. The key is to understand the human being as only contingently an animal. This approach to our animality is one that Catholics have additional reason to hold given certain views about purgatory, our uniqueness as free and rational creatures, and our having once existed as zygotes.

ABSTRACTJohn Locke is famous for popularizing the method of the philosophical thought experiment in discussions of personal identity; the cases introduced in the second edition of An Essay Concerning Understanding are still employed by contemporary philosophers. Here I argue that Locke’s method is nonetheless importantly different from later efforts in ways that can help us better appreciate his larger projects. Rather than pumping the reader’s intuitions in support of his preferred account, Locke’s thought experiments serve (...) to illustrate common errors in assessments of identity that he sees as particularly prevalent and problematic. Locke defends his idea of ‘person’ otherwise, through what I call his ‘lived experiments’: observations about linguistic usage that serve to illustrate the term’s role in practical reasoning. I focus especially on Locke’s example of the forensic status of the madman. Examples like these do not, for Locke, demonstrate the intuitiveness of his analysis, but rather bolste... (shrink)

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.

What are the metaphysical and metapsychological boundaries of a person? How do we draw our borders? This much is clear: personal identity without thought experiments is impossible. I develop a new way of conceptualizing physiological and psychological borders leading to a re-evaluation of the problem of personal identity within the contemporary literature, especially Parfit, arguing that we must, necessarily, turn to the conceptual analysis of metaphysical and metapsychological borders. I offer an explanation of the (...) persistence of common sense against philosophical analysis, criticize Wilkes's position, and provide a foundation for the proper use of thought experiments in analytic metapsychology and metaphysics.

This paper examines the role of episodic memory, and the broader notion of “mental time travel” (MTT), in constituting personal identity. After arguing that the construal of memory’s role in personal identity found in traditional psychological continuity theories of personal identity is both unrealistic and unsatisfying, the paper endeavors to provide a better account. This begins with recent work in the science and philosophy of memory that sees episodic memory as part of a broader (...) faculty for MTT (which also involves imagination and counterfactual thought). Some of the basic ideas expressed in this work are developed into an account of the connection between MTT with “strong identification” and personal identity. According to this alternative approach, we regularly “borrow affect” from our pasts and futures through forms of remembering, imagining, and counterfactual thinking that involve a particular form of identification with our past and future selves. This activity generates a strong diachronic experience of self, which contributes in important ways to diachronic personal identity. The sense of self generated through MTT is, however, only one piece of a more comprehensive account of personal identity. The paper concludes by describing its place in the larger picture. (shrink)

‘Transplant’ thought-experiments, in which the cerebrum is moved from one body to another, have featured in a number of recent discussions in the personal identity literature. Once taken as offering confirmation of some form of psychological continuity theory of identity, arguments from Marya Schechtman and Kathleen Wilkes have contended that this is not the case. Any such apparent support is due to a lack of detail in their description or a reliance on predictions that we (...) are in no position to make. I argue that the case against them rests on two serious misunderstandings of the operation of thought-experiments, and that even if they do not ultimately support a psychological continuity theory, they do major damage to that theory’s opponents.

Most philosophers writing about personal identity in recent years claim that what it takes for us to persist through time is a matter of psychology. In this groundbreaking new book, Eric Olson argues that such approaches face daunting problems, and he defends in their place a radically non-psychological account of personal identity. He defines human beings as biological organisms, and claims that no psychological relation is either sufficient or necessary for an organism to persist. Olson rejects (...) several famous thought-experiments dealing with personal identity. He argues, instead, that one could survive the destruction of all of one's psychological contents and capabilities as long as the human organism remains alive--as long as its vital functions, such as breathing, circulation, and metabolism, continue.

Martha Nussbaum has argued in support of the view (supposedly that of Aristotle) that we can, through thought-experiments involving personal identity, find an objective foundation for moral thought without having to appeal to any authority independent of morality. I compare the thought-experiment from Plato’s Philebus that she presents as an example to other thought-experiments involving identity in the literature and argue that this reveals a tension between the sources of authority which (...) Nussbaum invokes for her thought-experiment. I also argue that each of her sources of authority presents further difficulties for her project. Finally, I argue that it is not clear that her thought-experiment is one that actually involves identity in any crucial way. As a result, the case she offers does not offer any satisfactory support for her view on the relation between identity, morality and thought-experiments, but we do gain some insights into what that relation really is along the way.

This paper intends to discuss some aspects of what we conceive as personal identity: what it consists in, as well as its alleged fragility. First I will try to justify the methodology used in this paper, that is, the use of allegories in ontological debates, especialy in the form of thought experiments and science fiction movies. Then I will introduce an original thought experiment I call “Who am I actually?,” one that was coined with the (...) intent to shed light on several aspects of the issue under examination, that is, the fragility of personal identity. Then I will move on to Christopher Nolan’s film The Prestige, as well as to Derek Parfit’s ‘divided minds’ thought experiment, to further discuss the fragility of personal identity; next to identity theft, the prospect of duplication is also intriguing, especially with regard to the psychological impact this might have on both the prototype and the duplicate. I will conclude with the view that spatial and temporal proximity or coexistence, especially when paired with awareness on behalf of the duplicates, would expectedly result in the infringement of the psychological continuity of one’s identity.

The project takes as its starting point our conflicting intuitions about personal identity exposed by Bernard Williams' thought experiment involving the switching of bodies in "The Self and the Future." The conflicted intuitions are identified as animalist and psychologist and correspond roughly with the two major approaches to personal identity. The traditional strategy to resolve the conflict---thought experiments---is critically examined and the project concludes that proper thought experiments will reveal the conflict (...) but are unlikely to resolve it. A new reading of the conflict is proposed. The concept of the person is a cluster concept with distinct components: biological human beings, rational agency and psychological continuity, where the latter is construed as the temporal analog of phenomenological unity at a time. The project then suggests that moral theory is best pursued not by a naturalist conception of persons that unites the components of the cluster, but by a novel conception that separates them. This can be accomplished best by eliminating the concept of the person altogether. Objections that the concept of the person is ineliminable are considered and rejected, as are objections that the nature of conflict is not reason enough to abandon the concept. Personhood's centrality for value theory is questioned and the eliminativist strategy is defended on the grounds that responsibility, self-concern and moral rights are best analyzed with the component concepts instead of the cluster concept. Eliminativism is therefore preferable to competing accounts of personal identity because the former is better suited for moral theory. Among the advantages are the ability to: attribute responsibility to group agents without calling them persons, make sense of our conflicting demonstrations of self-concern without taking them as evidence for conflicting theories of personal identity, and attribute moral rights to entities who fail to meet traditional criteria for personhood but who are nonetheless entitled to moral respect.

Philosophers have traditionally used thought-experiments in their endeavours to find a satisfactory account of the self and personal identity. Yet there are considerations from empirical psychology as well as related ones from philosophy itself that appear to completely undermine the method of thought-experiment. This paper focuses on both sets of considerations and attempts a defence of the method.

The non-identity problem, which is much discussed in bioethics, metaphysics and environmental ethics, is usually examined by philosophers because of the difficulties it raises for our understanding of possible harms done to present human agents. In this article, instead of attempting to solve the non-identical problem, I explore an entirely different feature of the problem, namely the implications it has for the admissibility of outlandish or bizarre thought experiments. I argue that in order to sustain the claim (...) that later born selves cannot be harmed (since they are in fact different persons), one must rule inadmissible certain kinds of modally bizarre imaginary cases. In this paper I explore how one might justify such a constraint on outlandish cases and, in so doing, develop the outline of a model for distinguishing between admissible and inadmissible imaginary cases in philosophical debate.

Thought experiments that concoct bizarre possible world modalities are standard fare in debates on personal identity. Appealing to intuitions raised by such evocations is often taken to settle differences between conflicting theoretical views that, albeit, have practical implications for ethical controversies of personal identity in health care. Employing thought experiments that way is inadequate, I argue, since personhood is intrinsically linked to constraining facts about the actual world. I defend a moderate modal (...) skepticism according to which intuiting across conceptually incongruent worlds constitutes ‘invalid intuitioninferences’—i.e., carrying over intuitions gathered from facts about possible worlds that are at odds with facts about the actual world, for the purpose of making claims about real-life persons and their identity, leads to conceptual incongruences. Such a methodological fallout precludes accurate, informative judgments about personal identity in the actual world, calling into question the adequacy of thought experimental considerations for potential real world applications in medical ethics.

Compatibilists disagree over whether there are historical conditions on moral responsibility. Historicists claim there are, whilst structuralists deny this. Historicists motivate their position by claiming to avoid the counter-intuitive implications of structuralism. I do two things in this paper. First, I argue that historicism has just as counter-intuitive implications as structuralism when faced with thought experiments inspired by those found in the personal identity literature. Hence, historicism is not automatically preferable to structuralism. Second, I argue that (...) structuralism is much more plausible once we accept that personal identity is irrelevant to moral responsibility. This paves the way for a new structuralist account that makes clear what it takes to be the diachronic ownership condition (which is normally taken to be personal identity) and the locus of moral responsibility (which is normally taken to be ‘whole’ person), and helps to alleviate the intuitive unease many have with respect to structuralism.

Thought experiments have been used by philosophers for centuries, especially in the study of personal identity where they appear to have been used extensively and indiscriminately. Despite their prevalence, the use of thought experiments in this area of philosophy has been criticized in recent times. Bernard Williams criticizes the conclusions that are drawn from some experiments, and retells one of these experiments from a different perspective, a retelling which leads to a seemingly (...) opposing result. Wilkes criticizes the method of thought experimentation itself, suggesting that the results drawn from the experiments are tainted by a faulty method. This paper examines both these types of objection, and concludes that neither can be sustained. (shrink)

Thought experiments are usually employed by philosophers as a tool in conceptual analysis. We pose ourselves questions such as “Would it be the same F if p?” or “Would it count as knowledge if q,” where p and q state some bizarre circumstances that are unlikely actually to occur and may even be beyond current technical possibility. The answers we are inclined to give to such questions are held to throw light on the nature of our concepts of, (...) in these cases, identity and knowledge. But the facts about our concepts that are unearthed in this way are implicitly assumed to be deep, not superficial, facts. They are not meant to be facts contingent upon our current linguistic usage, psychology, or social structure, where these could easily be otherwise. If they were just facts of this superficial kind, it would hardly be worth the effort of uncovering them, for they would bind no-one who preferred a different convention or practice. The conceptual truths revealed are meant to be unavoidable, in some sense, and not merely conventional: there is something Platonic or Kantian in the background. The argument of Sections 2–8 of this essay is that, in the case of the thought experiments used to throw light on our concepts of person and personal identity, the results do not seem to be deep or hard to revise, and that this is so largely because of the ontological assumptions shared by more or less all participants in the debate. I shall be arguing that it is primarily these ontological assumptions, rather than the insight into our concepts that the thought experiments are supposed to bring, that determine the answers to the questions about persons and their identity. In the final two sections I shall make some cautious qualifications to this conclusion. (shrink)

Williams (1970) argues that our intuitions about personal identity vary depending on how a given thought experiment is framed. Some frames lead us to think that persistence of self requires persistence of one's psychological characteristics; other frames lead us to think that the self persists even after the loss of one's distinctive psychological characteristics. The current paper takes an empirical approach to these issues. We find that framing does affect whether or not people judge that persistence of (...) psychological characteristics is required for persistence of self. Open-ended, abstract questions about what is required for survival tend to elicit responses that appeal to the importance of psychological characteristics. This emphasis on psychological characteristics is largely preserved even when participants are exposed to a concrete case that yields conflicting intuitions over whether memory must be preserved in order for a person to persist. Insofar as our philosophical theory of personal identity should be based on our intuitions, the results provide some support for the view that psychological characteristics really are critical for persistence of self.

In this dissertation, I defend an answer to the following question in the diachronic personal identity debate: what are the necessary and sufficient conditions for our persistence over time? Two popular approaches to answering this question are the psychological and the somatic approach. On the former approach, we persist in virtue of some sort of psychological continuity. So, some proponents of the psychological approach think that we cease to exist if we lose certain features of our psychology such (...) as our memories, beliefs, and rationality. On the latter approach, we persist in virtue of some sort of physical continuity. Eric Olson defends a version of the somatic approach called animalism. On his view, we are numerically identical to biological organisms and we persist if and only if the organisms we are persist. Although Olson’s animalism has some benefits, it also faces some challenges. For example, many people would say that we go wherever our brains go (if we go anywhere at all) because our brains (more specifically, our cerebra) realize the aspects of our psychology traditionally associated with persons, such as memories, beliefs, rationality, and self-awareness. But on Olson’s animalism, our psychology has nothing to do with our persistence and we go wherever our bodies go rather than our cerebra. Following Aristotle and Aquinas, I lay out an animalist view of our persistence called hylomorphic animalism. On this view, we are numerically identical to rational animals, which are living bodies composed of prime matter and a rational soul. Furthermore, we persist if and only if the composite of matter and rational soul persists. I claim that hylomorphic animalism makes better sense of certain contemporary personal identity thought experiments than Olson’s animalism. For example, contra Olson, I argue that our psychology does have something to do with our persistence and that we go wherever our brains go. (shrink)

The concept of the person, and the notion that the latter is an entity separate and distinct from other persons, has persisted as one of the more secure ‘givens’ of philosophical thought. We have very little difficulty, in observer language, in pointing to a person, describing his or her attributes, distinguishing him or her from other persons, etc. Likewise, it is ordinarily not much of a problem to subjectively experience, both sensorially and conceptually, the self – that is, to (...) distinguish in agent language ‘my person’ from the rest of the universe. The second of these two perspectives on the person defines the ‘I,’ ‘ego,’ or ‘identity.’ Several recent developments in experimental psychology and brain science – while not defeating the ordinary notion of the person on the merits of data per se – at least force a re-thinking of tacit assumptions basic to our sense of the concepts of both the person and personal identity. In this paper, I would like to show how the concept of the person needs revision, and at the same time to raise some objections to Shaffer's (1977) account of the consequences of brain bisection and brain transplant with respect to the fate of the person and his identity.

Locke’s theory of personal identity was philosophically groundbreaking for its attempt to establish a non-substantial identity condition. Locke states, “For the same consciousness being preserv’d, whether in the same or different Substances, the personal Identity is preserv’d” (II.xxvii.13). Many have interpreted Locke to think that consciousness identifies a self both synchronically and diachronically by attributing thoughts and actions to a self. Thus, many have attributed to Locke either a memory theory or an appropriation theory of (...) personal identity. But the former stumble on circularity and the latter is insufficient for Locke’s moral theory insofar as he is committed to a theory of divine rectification. The common problem is that Locke’s theory seems to demand an objective, or metaphysical, fact of a continuing consciousness that does not appeal to a traditional notion of substance for the continuity. I’m suggesting something new. In II.xxvii of the Essay, we see an ambiguity in Locke’s use of the term ‘consciousness’. Locke seems to see consciousness as both a mental state by means of which we are aware of ourselves as perceiving and as the ongoing self we are aware of in these conscious states. First, I make the textual argument why we should read Locke as having a conception of a metaphysical fact of a continuing consciousness that does not appeal to thinking or bodily substance to establish its continuity. I then argue that the metaphysical fact of an enduring consciousness is revealed to us as a phenomenological fact of experience. Due to the nature of certain kinds of perceptual situations we have an experience of ourselves as temporally extended. Although the text bears out that Locke seemed to think there is a fact of an ongoing consciousness, I argue that it is consistent with his reluctance elsewhere that he makes no further epistemological or ontological claims about it. Finally, I provide an account of Locke’s understanding of memory and its relation to consciousness that supports the claim that consciousness is something ontologically distinct from either thinking or bodily substance.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Beyond Personal Identity: Dōgen, Nishida, and a Phenomenology of No-SelfCarl OlsonBeyond Personal Identity: Dōgen, Nishida, and a Phenomenology of No-Self. By Gereon Kopf. Richmond, UK: Curzon Press, 2001. 298 + xx pp.This work of comparative philosophy focuses on the problem of the self by comparing Western existential and phenomenological thought with Zen thinkers such as Dōgen and Nishida. In addition to such thinkers (...) as Jean-Paul Sartre, Merleau-Ponty, Edmund Husserl, and Martin Heidegger, the author also includes a discussion of such Western philosophers as Descartes, Kant, Leibniz, Lock, and Hume. The author demonstrates a knowledgeable command of his subjects and the central focus of the book.After discussing the problem of personal identity in the first part of the book, the author uses the second part of the book to place phenomenologists into dialogue with Zen Buddhist thinkers. The second part of the book includes the following topics: selfhood, otherness, continuity of experience, and temporality. In the final part of the book, the author considers the Zen conception of personal identity by discussing a Zen phenomenology of experience and personhood as presencing. Within the context of this final part of the book, Kopf wants to develop terminology that derives from both phenomenology and Zen Buddhism in order to consider the Zen notion of no-self as a process of presencing. This approach gives the author an opportunity to explore the philosophical implications of Zen Buddhist terminology and rhetoric and to suggest a way to theorize and discuss the self beyond personal [End Page 200] identity. Overall, each of the three parts of the book provides a different perspective: a discourse on personal identity, a comparative philosophical perspective, and a Zen viewpoint.This work of comparative philosophy embodies an internal tension between the position of the author and the impermanent nature of the non-self in Zen Buddhism. Kopf acknowledges his basic position in the following way: "It is my thesis that the framing of the question of personal identity already implies the notion of an enduring self" (p. xviii). In contrast, Dōgen rejects the notion of an enduring self or personal identity. The author's stated thesis and that of Zen Buddhism suggests that continuity is a crucial issue for this book.In chapter 4, Kopf elucidates his understanding of the continuity of experience: "The notion of continuity reflects the assumption that the 'I' of human experience is not without a history: It finds itself in the context of past experiences, which the experiental 'I' encounters in memories, as well as in a given situation" (p. 124). In short, a person finds oneself thrown into a situation. After discussing Sartre, Merleau-Ponty, the non-self doctrine in early Buddhism, how the Mahāyāna thinker Vasubandhu attributes continuity of experience to the habit energy produced by karmic activity, and how Nāgārjuna collapses the distinction between sam.sāra and nirvan.a, the author considers the positions of Dōgen and Nishida. The former defines the continuity of experience by two diachronically diverse dharma positions instead of three moments of time. This position suggests that Dōgen views continuity as the process from the present to the present and not as a process that operates from the past into the future. According to Nishida, the I-Thou forms a nonrelative contradictory self-identity, and it exists in the world of expression. This implies that the self is simultaneously continuous and discontinuous.In his chapter on temporality, Kopf distinguishes between abstract time, phenomenal time, lived time, and actual time, which is a fourth dimension suggested by Dōgen and Nishida. Abstract time is rejected because time is inseparable from existence. Grasping time as a dynamic event, the author discusses phenomenal time, in which the self realizes its own temporality and historicity. In contrast to the threefold structure of abstract time, phenomenal time possesses a twofold structure of past and future, whereas lived time embodies an internal unity in which the present unifies the past and future. A fourth dimension of time—actual time—is suggested by the work of Dōgen and Nishida. Actual time expresses a "modality of... (shrink)

In this paper, I identify and discuss the following feature of our judgments about hypothetical scenarios concerning the identity of persons: with respect to the vast majority of scenarios, both members of a pair of logically complementary propositions about personal identity are conceivable. I consider a number of explanations of this feature that draw on the metaphysics and the epistemology of personal identity, none of which prove to be satisfactory. I then argue that in order (...) to give an adequate explanation, one needs to recognize an important characteristic of our concept of personal identity: it is such that if there are mental substances (or the like), they constitute personal identity. At the same time, there can still be persons if there are no such substances. Since this finding casts doubts on the way that thought experiments about personal identity are usually set up, I end by outlining its potential consequences for the debate over the identity of persons. (shrink)

According to the psychological account of personal identity for someone to be one and the same person over time Y today must have some of the beliefs, desires, intentions and memories that X had yesterday, as well as some memories of the events that happened to X yesterday. But, on this account, we have the undesirable result that persons can be reduplicated unless we add an additional requirement: Y is uniquely psychologically continuous with X. In an attempt to (...) avoid the problem of reduplication in a different way I invoke arguments for active externalism and the embodied mind. The motivation for exploring embedded and embodied approaches to cognition is that they cast doubt on the easy separation of brain and body which is often taken for granted in the identity literature. With these approaches in mind, the simple assumptions by which brains are imagined to be transplanted into new bodies, and agents are said to be teletransported to new environments should be reviewed. Whilst embodiment provides us with some reasons to re-evaluate our understanding of brain transplant thought experiments, we ultimately see that the nature of teletransportation is consistent with the mind as both extended and embodied.

By a generalization of Parfit’s argument for the unimportance of personal identity in survival, it is argued that the practical significance that appears to attach to our identity belongs to the relation of direct control, which we exercise through will. What explains the special concern and moral responsibility that normally pertains only to ourselves is that it is ordinarily just ourselves whom we animate by our decisions. But thought experiments involving amnesia and replication seem to (...) show that direct control only contingently coexists with personal identity. If so, the practically important question is whom we can control directly and the metaphysical question of our identity may be of only theoretical interest. The practical importance of the metaphysics of personal identity is defended by showing that our beliefs about which things we are determine what we can will. Such beliefs influence emotions of fear and the like and circumscribe our sense of responsibility. (shrink)

The author, a member of the faculty in philosophy at Visva-Bharati University, produced this volume under appointment as Visiting Fellow at the Indian Institute of Advanced Study, after having studied in England. These four essays are concerned with recent analytic thought, concentrating upon the problem of identity and the experiments of reflection which have appeared in modern British philosophy, such as Strawson’s world of nothing but sound. Chandra’s central concern is to analyse the relationship between identity (...) and continuity, and to show that these concepts are not identical. Thus the book is an extended essay in conceptual clarification and logical geography. Saying that a is identical with b is not to say that a is continuous with b. All of this is undertaken because the author finds this inappropriate identification pervasive in contemporary philosophy, and the source of considerable logical confusion, especially in the consideration of personal identity. As an underlying theme attention is also focused upon the relevance of this issue to the debate concerning philosophical skepticism. Strawson’s sound world is seen as an attempt to refute the skeptic, which attempt fails because of Strawson’s failure to distinguish between identity and continuity. With the failure of Strawson’s attack upon the skeptic, and perhaps the phenomenalist as well, his defense of material bodies is thereby undermined. In addition to Strawson, Chandra studies Price, Ryle, Hick, and the very recent work on personal identity by Parfit. The author concludes that identity is consistent with discontinuous existence. He also offers an analysis of after-images, including not only visual after-images but after-images of taste as well. A further underlying theme is the use of science in such thought experiments, for they are frequently presented as if they were of a scientific character, thus exaggerating scientific capabilities. However, the nature of the relationship between philosophy and science is hardly clarified, and the nature of scientific limits remains vague throughout the book. Chandra has isolated a unique feature of contemporary analytic philosophy for consideration, for few others have so concentrated upon this strange feature of thought experiment which pervades British philosophy, nor the identification of identity and continuity. The book would have been improved tremendously, however, if the author had only indicated much more clearly than he does the philosophical conclusions which he wishes to draw from his reflections. These constantly remain uncertain and ambiguous.—H.A.D. (shrink)

Can some films be genuine thought experiments that challenge our commonsense intuitions? Certain filmic narratives and their mise-en-scène details reveal rigorous reasoning and counterintuitive outcomes on philosophical issues, such as skepticism or personal identity. But this philosophical façade may hide a mundane concern for entertainment. Unfamiliar narratives drive spectator entertainment, and every novel cinematic situation could be easily explained as part of a process that lacks motives of philosophical elucidation. -/- The paper inverses the above objection, (...) and proposes that when the main cinematic character resists spectator engagement (a crucial source of cinematic entertainment), emotionally challenged spectators also question their commonsensical beliefs about his/her actions, and detect a conceptually novel situation as such. -/- A case study is Mike Leigh’s film Happy-Go-Lucky (2008), in which the main female character presents an unrelenting but eccentric version of 'feel good' happiness. Spectators gradually detect that the previously unexamined, commonsensical version of subjective happiness comes at the price of individual eccentricity, and that the choice of a subjective theory of happiness leads to consequences hitherto unacknowledged.

The Naked Self explores Søren Kierkegaard's understanding of selfhood by situating his work in relation to central problems in contemporary philosophy of personal identity: the role of memory in selfhood, the relationship between the notional and actual subjects of memory and anticipation, the phenomenology of diachronic self-experience, affective alienation from our past and future, psychological continuity, practical and narrative approaches to identity, and the intelligibility of posthumous survival. By bringing his thought into dialogue with major living (...) and recent philosophers of identity, Stokes reveals Kierkegaard as a philosopher with a significant--if challenging--contribution to make to philosophy of self and identity.

In lieu of an abstract, here is a brief excerpt of the content:Personal Identity and the Moral Authority of Advance DirectivesAndrea OttSection 1What is the metaphysical basis for respecting an advance directive first drawn up by an individual who is competent but who is at present rendered incapacitated?1 What are the roles of autonomy, personal values, integrity, and beneficence contained within said respect? In this section the positions of two prominent philosophers, Ronald Dworkin and Jeff McMahan, will (...) be analyzed with regard to the above questions. While the two thinkers have different scholastic orientations—with Dworkin primarily a philosopher of law and McMahan an ethicist and metaphysician—their conclusions regarding the respect of the wishes of the competent-turned-demented are remarkably similar. Namely, they both argue that the values and desires held by the previously competent agent trump any current (contrary) wishes. What this amounts to for Dworkin involves respecting the autonomy of the dominant, competent part of the life where countermanding such autonomy would be worse for the life as a whole. For McMahan this means respecting the precedent autonomy generated by the deep prudential unity relations which form the basis for egoistic concern; this concern is often the basis for drafting a directive regarding future care in the first place.I will argue in this paper that if McMahan is to be consistent with his position regarding prudential unity relations then he will, in fact, not arrive at the same conclusion as Dworkin.2 Consistency will demand that the demented patient’s directive should not be followed because the demented individual will, at best, be only weakly connected to the previously autonomous, decision-capable agent. Therefore, I will argue, the moral authority [End Page 38] of the advance directive will be similarly weakened. According to McMahan, Dworkin maintains that the precedent autonomous decision has moral authority, for he assumes that the individual in question is understood to be one “temporally extended individual,” so that what is best for her life now will, in fact, be what is best for her life as a whole (501). McMahan claims to support Dworkin’s conclusion, albeit for different reasons. McMahan supports the execution of the directive out of some sort of respect for the earlier “reasonably full and complete life with its own deep prudential unity” (502). I argue that McMahan, though ostensibly in agreement with Dworkin, will have to acknowledge that the weakened prudential unity relations which make the life as a whole matter less will also undercut the moral authority of the directive. In other words, the moral authority of an advance directive weakens as the prudential unity relations weaken.Ultimately, I believe, Lynne Baker and her metaphysics of constitution can provide the best direction when faced with dilemmas such as The Advance Directive. Baker can do this and avoid the charge of positing a “post-person” (the basis for McMahan’s criticism of other versions of psychological accounts of personal identity). I use her metaphysics of constitution and derivative properties within a novel explanation of prudential concern for the organism without positing identity. I argue, in section 2, that the organism made the decision for advance care when it was derivatively (in Baker’s sense) a person. We can thus avoid the charges of (1) new entities “popping” into existence and (2) a person binding a nonperson. Such a metaphysics of constitution may thus offer some hope of adjudication within debate concerning these matters.Now I shall turn to the thought experiment in The Ethics of Killing that forms the basis of this discussion. True to the general style of his work, Jeff McMahan asks the reader to consider a thought experiment. To avoid any misinterpretation of the facts, I reproduce The Advance Directive in full below:A woman whose life has been devoted to creative intellectual work finds herself in the very early stages of Alzheimer’s disease. Given her nature, her values, and the character of her previous life, she believes that for her to continue to live in a demented state would be horribly degrading, worse than simply ceasing to exist. She accepts, however, that her life will continue to be worth living as long as she remains competent; therefore to commit... (shrink)
