Don Marquis' future‐like‐ours account is regarded as the best secular anti‐abortion position because he frames abortion as a wrongful killing via deprivation of a valuable future. Marquis objects to the reductio ad absurdum of contraception as being immoral because it is too difficult to identify an individual that is deprived of a future. To demonstrate why Marquis’ treatment of the contraception reductio is flawed by his own future‐like‐ours line of reasoning, I offer an argument for why there is indeed a (...) candidate for harm—the ovum—for it can be viewed as providing the functional foundation for a new life through (1) mitochondrial DNA inheritance, (2) paternal histone restructuring during fertilization, and (3) ability to initiate parthenogenesis. As evidenced by these distinct and natural features of ova, candidate (2) “some ovum or other” should be morally prioritized as the direct candidate for harm in the contraception reductio. By assessing the philosophical inconsistencies in Marquis’ future‐like‐ours argument, this paper provides strong metaphysical grounds for rejecting the best secular anti‐abortion position. (shrink)

In the recent neuroethics literature, there has been vigorous debate concerning the ethical implications of the use of neurotechnologies that may alter a person’s identity. Much of this debate has been framed around the concept of authenticity. The argument of this chapter is that the ethics of authenticity, as applied to neurotechnological treatment or enhancement, is conceptually misleading. The notion of authenticity is ambiguous between two distinct and conflicting conceptions: self-discovery and self-creation. The self-discovery conception of authenticity is based (...) on a problematic conception of a static, real inner self. The notion of self-creation, although more plausible, blurs the distinction between identity and autonomy. Moreover, both conceptions are overly individualistic and fail sufficiently to account for the relational constitution of personal identity. The authors propose that a relational, narrative understanding of identity and autonomy can incorporate the more plausible aspects of both interpretations of authenticity, while providing a normatively more illuminating theoretical framework for approaching the question of whether and how neurotechnologies threaten identity.

Applies Dogen Kigen's religious philosophy and the philosophy of Nishida Kitaro to the philosophical problem of personal identity, probing the applicability of the concept of non-self to the philosophical problems of selfhood, otherness, and temporality which culminate in the conundrum of personal identity.

The central fact about the problem of personal identity is that it is a problem posed by an apparent dichotomy: the dichotomy between the objective, third-person viewpoint on the one hand and the subjective perspective provided by the first-person viewpoint on the other. Everyone understands that the mind/body problem is precisely the problem of what to do about another apparent dichotomy, the duality comprising states of consciousness on the one hand and physical states of the body on the (...) other. By contrast, contemporary discussions of the problem of personal identity generally display little or no recognition of the divide which to my mind is at the heart of the problem. As a consequence, there has been a relentlessly third-personal approach to the issue, and the consequent proposal of solutions which stand no chance at all of working. I think the idea that the problem is to be clarified by an appeal to the idea of a human being is the latest manifestation of this mistaken approach. I am thinking in particular of the claim that what ought to govern our thinking on this issue is the fact that human beings constitute a natural kind, and that standard members of this kind can be said to have some sort of essence. Related to this is the idea that ‘person’, while not itself a natural kind term, is not a notion which can be framed in entire independence of this natural kind. (shrink)

Our aim in this entry is to articulate the state of the art in the moral psychology of personal identity. We begin by discussing the major philosophical theories of personal identity, including their shortcomings. We then turn to recent psychological work on personal identity and the self, investigations that often illuminate our person-related normative concerns. We conclude by discussing the implications of this psychological work for some contemporary philosophical theories and suggesting fruitful areas for (...) future work on personal identity. (shrink)

The view that it is possible for someone to think at a time without existing at that time is not only perfectly coherent but in harmony with an attractive externalist view of the mental. Furthermore, it offers plausible solutions to various puzzles of personal identity.

Given that all Buddhists give universal scope to the no-self view, accounts of personal identity in Buddhism cannot rest on egological conceptions of self-consciousness. Without a conception of consciousness as the property, function, or dimension of an enduring subject or self, how, then, do mental states acquire their first-personal character? What it is that in virtue of which mental states exhibit a basic or minimal sense of self? These questions are at the heart of a long debate (...) about the nature and character of consciousness and self-consciousness. This paper traces the genealogy of key concepts of consciousness and personal identity in Buddhism, their role in articulating specific accounts of self-knowledge, and their relevance to contemporary debates in phenomenology and philosophy of mind about the relation between consciousness and self-consciousness.

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.

This paper aims to provide an overview of the conceptual terrain of what we call conative accounts of personal identity. These are views according to which the same-person relation in some sense depends on a range of broadly conative phenomena, especially desires, behaviours and conventions. We distinguish views along three dimensions: what role the conations play, what kinds of conations play that role, and whether the conations that play that role are public or private. We then offer a (...) more detailed consideration of direct private conativism—the version of conativism that we favour—before considering how conativists ought respond to a general worry, according to which any conativist view will lead us to be radically pluralist about persons.

In this paper I outline and defend a new approach to personal-identity—personal-identity non-cognitivism—and argue that it has several advantages over its cognitivist rivals. On this view utterances of personal-identity sentences express a non-cognitive attitude towards relevant person-stages. The resulting view offers a pleasingly nuanced picture of what we are doing when we utter such sentences.

The personal identity relation is of great interest to philosophers, who often consider fictional scenarios to test what features seem to make persons persist through time. But often real examples of neuroscientific interest also provide important tests of personal identity. One such example is the case of Phineas Gage – or at least the story often told about Phineas Gage. Many cite Gage’s story as example of severed personal identity; Phineas underwent such a tremendous (...) change that Gage “survived as a different man.” I discuss a recent empirical finding about judgments about this hypothetical. It is not just the magnitude of the change that affects identity judgment; it is also the negative direction of the change. I present an experiment suggesting that direction of change also affects neuroethical judgments. I conclude we should consider carefully the way in which improvements and deteriorations affect attributions of personal identity. This is particularly important since a number of the most crucial neuroethical decisions involve varieties of cognitive enhancements or deteriorations. (shrink)

In this paper, I offer a conceptual framework for understanding and evaluating personal identity claims. I analyze ontological and political properties of personal identity separately, arguing that their conceptual (if not practical) separation is necessary for a proper evaluation of different identity claims. I use probability theory to bypass some of the logical difficulties in conceptualizing personal identity and discuss a case of transitional identification. Finally, I outline the guidelines for a justified liberal (...) policy of recognition. (shrink)

Personal identity is not always symmetric: even if I will not be a later person, the later person may have been me. What makes this possible is that the relations that are criterial of personal identity---such as memory and anticipation---are asymmetric and "count in favor of personal identity from one side only". Asymmetric personal identity can be accommodated by temporal counterpart theory but not by Lewisian overlapping aggregates of person stages. The question (...) of uncertainty in cases of personal fission (and in Everettian quantum mechanics) is also discussed. (shrink)

Phineas Gage’s story is typically offered as a paradigm example supporting the view that part of what matters for personal identity is a certain magnitude of similarity between earlier and later individuals. Yet, reconsidering a slight variant of Phineas Gage’s story indicates that it is not just magnitude of similarity, but also the direction of change that affects personal identity judgments; in some cases, changes for the worse are more seen as identity-severing than changes for (...) the better of comparable magnitude. Ironically, thinking carefully about Phineas Gage’s story tells against the thesis it is typically taken to support. (shrink)

What is a person? What makes me the same person today that I was yesterday or will be tomorrow? Philosophers have long pondered these questions. In Plato's Symposium, Socrates observed that all of us are constantly undergoing change: we experience physical changes to our bodies, as well as changes in our 'manners, customs, opinions, desires, pleasures, pains, [and] fears'. Aristotle theorized that there must be some underlying 'substratum' that remains the same even as we undergo these changes. John Locke rejected (...) Aristotle's view and reformulated the problem of personal identity in his own way: is a person a physical organism that persists through time, or is a person identified by the persistence of psychological states, by memory? These essays - written by prominent philosophers and legal and economic theorists - offer valuable insights into the nature of personal identity and its implications for morality and public policy.

Kevin Tobia on how our intuitions about personal identity reflect moral norms.

Personal identity deals with questions about ourselves qua people (or persons). Many of these questions are familiar ones that occur to everyone at some time: What am I? When did I begin? What will happen to me when I die? Discussions of personal identity go right back to the origins of Western philosophy, and most major figures have had something to say about it. (There is also a rich literature on personal identity in Eastern (...) philosophy, which I am not competent to discuss. Collins 1982 is a good source.). (shrink)

In contemporary western philosophy, there are two major positions on the issue of personal identity, the one upholding the substantive notion of an enduring ego, the other rejecting the idea of an enduring subject completely. While the substantive position seems to be untenable in the light of contemporary cognitive science and philosophy of mind, the rejection of an enduring agency has left unanswered the questions of subjective agency, ethical responsibility and accountability. In contrast to these approaches, Buddhism has (...) long upheld a conception which, while rejecting the problematic notion of an enduring person or self, does not dispense with the notion of subjective agency. My dissertation will formulate such a non-substantive notion of personhood based on the Buddhist theory of self-cultivation. ;My dissertation commences with a critique of the present theories of personal identity and the assumptions underlying the very notion of personal identity. In the light of this criticism, the notion of "Mensch-sein" seems to be more appropriate than the notion of "personal identity." With this as a basis, the dissertation offers a new conception of Mensch-sein, drawing on Dogen's theory of self-cultivation and Jung's notion of individuation. It will especially investigate the phenomena of selfhood, alterity, and continuity. It is my belief that such an understanding of Mensch-sein not only contributes to a comparative philosophy of personhood and of the mind but also provides a conceptual tool to understand latest developments in cognitive science and psychology. Thus, it illustrates that the study of religion contributes to the systematized understanding of the world. (shrink)

The Research Studies The Problem Of Personal Identity, Dealing With The Nature/Source Of The Problem, The Approach Of Traditional/Modern Philosophers And Its Proper Analysis. It Finally Shows That Bodily Continuity Is The Primary Criterion Of Personal Identity.

There is a connection between moral facts and personal identity facts: morality grounds personal identity. If, for example, old Sally enters a teletransporter, and new Sally emerges, the fundamental question to ask is: is new Sally morally responsible for actions (and omissions) of old Sally? If the moral facts are such that she is morally responsible, then Sally persisted through the teletransporter event, and if not, Sally ceased to exist.

What is the self? And how does it relate to the body? In the second edition of Personal Identity, Harold Noonan presents the major historical theories of personal identity, particularly those of Locke, Leibniz, Butler, Reid and Hume. Noonan goes on to give a careful analysis of what the problem of personal identity is, and its place in the context of more general puzzles about identity. He then moves on to consider the main (...) issues and arguments which are the subject of current debate, including the work of Bernard Williams and Derek Parfit, and makes new and challenging interpretations of them. This new edition contains additional material assessing the biological approach which has become increasingly popular in recent years, and extends the treatment of indeterminate identity to take account of the epistemic view of vagueness. This book covers the problem of personal identity from its origin in Locke's work to the most recent debates in the philosophical literature, and will be invaluablereading for any student of the topic.

Self-interest is widely regarded as an important, if not as the only, source of reasons for action, and hence it is widely held that one can rationally give special weight to one’s self-interest in deciding how to act. In what follows, I will argue against this view. I will do so by following the lead of Derek Parfit, and considering cases in which personal identity appears to break down. My argument will differ from Parfit’s, however, in that it (...) will have a stronger conclusion, it will involve fewer assumptions, and it will be compatible with a wider range of theories of personal identity.

We take it for granted that a person persists over time: when we make plans, we assume that we will carry them out; when we punish someone for a crime, we assume that she is the same person as the one who committed it. Metaphysical questions underlying these assumptions point towards an area of deep existential and philosophical interest. In this volume, leading metaphysicians discuss key questions about personal identity, including 'What are we?', 'How do we persist?', and (...) 'Which conditions guarantee our identity over time?' They discuss whether personal identity is 'complex', whereby it is analyzable in terms of simpler relations such as physical or psychological features, or whether it is 'simple', namely something that cannot be analyzed in terms of more fundamental relations. Their essays offer an innovative discussion of this topic and will be of interest to a wide readership in metaphysics. (shrink)

Many philosophers hypothesize that our concept of personal identity is partly constituted by the one-person-one-place rule, which states that a person can only be in one place at a time. This hypothesis has been assumed by the most influential contemporary work on personal identity. In this paper, we report a series of studies testing whether the hypothesis is true. In these studies, people consistently judged that the same person existed in two different places at the same (...) time. This result undermines some widely held philosophical assumptions, supports others, and fits well with recent discoveries on identity judgments about inanimate objects and non-human animals.

This document consists primarily of an excerpt (chapter 5) from the author’s book From Brain to Cosmos. That excerpt presents an analysis of personal identity through time, using the concept of subjective fact that the author developed earlier in the book. (Readers unfamiliar with that concept are strongly advised to read chapters 2 and 3 of From Brain to Cosmos first. See the last page of this document for details on how to obtain those chapters.).

‘Soul’, ‘self’, ‘substance’ and ‘person’ are just four of the terms often used to refer to the human individual. Cutting across metaphysics, ethics, and religion the nature of personal identity is a fundamental and long-standing puzzle in philosophy. Personal Identity and Applied Ethics introduces and examines different conceptions of the self, our nature, and personal identity and considers the implications of these for applied ethics. A key feature of the book is that it considers (...) a range of different approaches to personal identity; philosophical, religious, and cross-cultural, including perspectives from non-Western traditions. Within this comparative framework, Andrea Sauchelli examines the following topics: -Early views of the soul in Plato, Christianity, and Descartes -The Buddhist ‘no-self’ views and the self as a fiction -Confucian ideas of our nature and the importance of self-cultivation as constitutive of the self -Locke’s theory of personal identity as continuity of consciousness and memory and objections to Locke’s argument by Butler and Reid as well as contemporary critics -The theory of ‘animalism’ and arguments concerning embodied concepts of personal identity -Practical and narrative theories of personal identity and moral agency -Personal identity and issues in applied ethics, including abortion, organ transplantation, and the idea of life after death -Implications of life-extending technologies for personal identity. Throughout the book Sauchelli also considers the views of important recent philosophers of personal identity such as Sydney Shoemaker, Bernard Williams, Derek Parfit, Marya Schechtman, and Christine Korsgaard, placing these in helpful historical context. Chapter summaries, a glossary of key terms, and suggestions for further reading make this a refreshing, approachable introduction to personal identity and applied ethics. It is an ideal text for courses on personal identity that consider both Western and non-Western approaches and that apply theories of personal identity to ethical problems. It will also be of interest to those in related subjects such as religious studies and history of ideas. (shrink)

This paper defends a version of strong conventionalism minus the ontological commitments of that view. It defends the claim that strictly speaking there are no persons, whilst explicating how to make sense of talk that is about (or purportedly about) persons, by appealing to features in common to conventionalist accounts of personal identity. This view has the many benefits of conventionalist accounts in being flexible enough to deal with problem cases, whilst also avoiding the various worries associated with (...) the existence of both persons and human animals occupying the same place at the same time to which conventionalist accounts are committed.

There are two main views about the nature of personal identity. I shall briehy describe these views, say without argument which I believe to be true, and then discuss the implications of this view for one of the main conceptions of rationality. This conception I shall call "C1assical Prudence." I shall argue that, on what I believe to be the true view about personal identity, Classical Prudence is indefensible.

There has been a call for a potentially revolutionary change to our existing understanding of the psychological concept of personal identity. Apparently, people can psychologically represent people, including themselves, as multiple individuals at the same time. Here we ask whether the intransitive judgments found in these studies truly reflect the operation of an intransitive concept of personal identity. We manipulate several factors that arbitrate between transitivity and intransitivity and find most support for transitivity: in contrast to (...) prior work, most participants do not make intransitive judgments when there is any reason to favor one individual over another. People change which single individual they personally identify with, depending on which individual competes more strongly or weakly for identity, rather than identifying with both individuals. Even when two individuals are identical and therefore both entitled to be the same person, we find that people make more transitive judgments once they understand the practical commitments of their responses (Experiment 4), and report not being able to actually imagine two perspectives simultaneously when reasoning about the scenario (Experiment 5). In short, we suggest that while people may make intransitive judgments, these do not reflect that they psychologically represent identity in an intransitive manner. (shrink)

_Personal Identity and Self-Consciousness_ is about persons and personal identity. What are we? And why does personal identity matter? Brian Garrett, using jargon-free language, addresses questions in the metaphysics of personal identity, questions in value theory, and discusses questions about the first person singular. Brian Garrett makes an important contribution to the philosophy of personal identity and mind, and to epistemology.

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)
