In this paper, I defend the idea that we need a metaphysical theory to justify identity-related practical concerns, such as self-concern. I outline D. Parfit’s theory, in which the concerns receive a metaphysical justification. Then, I focus on two objections: C. Korsgaard’s claim that the concerns are justified by the unity of agency, and M. Johnston’s contention that the concerns are prima facie justified independently of a metaphysical theory. I argue that even if these theories (...) have a point, they do not cover a range of situations in which justification may be sought. It is in these situations that a metaphysical theory may find its place. (shrink)

When talking about personal identity in the context of medical ethics, ethicists tend to borrow haphazardly from different philosophical notions of personal identity, or to abjure these abstract metaphysical concerns as having nothing to do with practical questions in medical ethics. In fact, however, part of the moral authority for respecting a patient’s self-regarding decisions can only be made sense of if we make certain assumptions that are central to a particular, psychological picture of personal (...) identity, namely, that patients will remain psychologically connected to a certain degree with their future selves. I draw this out, show problems with approaches in medical ethics based on alternate theories of personal identity that do not recognise this, and explore some important implications. Namely, I show how this recognition can better explain the circumstances under which we should respect advance directives and why, and how it can better make sense of patient fears that they will not "survive" personality-altering deep brain stimulation procedures, and provide guidance on approaching patient decisions concerning this type of procedure in a manner that captures and addresses such concerns.

This paper focuses on three theories of personal identity that incorporate the idea that personal identity is the result of a person’s adopting certain attitudes towards certain mental states and actions. I call these theories subjective theories of personal identity. I argue that it is not clear what the proponents of these theories mean by “personal identity”. On standard theories, such as animalism or psychological theories, the term “personal identity” refers to the numerical identity of (...) persons and its analysis provides the persistence conditions for persons. I argue that if the subjective theories purport to provide a criterion of numerical personal identity, they fail. A different interpretation may suggest that they purport to provide a non-numerical type of identity for the purpose of providing plausible analyses of certain identity-related practical concerns. I argue that the criteria the subjective theories provide fail to capture several of the identity-related concerns. As a result, this interpretation must be rejected as well. (shrink)

I want to examine the implications of a metaphysical thesis which is presupposed in various objections to Rawls' theory of justice.Although their criticisms differ in many respects, they concur in employing what I shall refer to as the continuity thesis. This consists of the following claims conjointly: (1) The parties in the original position (henceforth the OP) are, and know themselves to be, fully mature persons who will be among the members of the well-ordered society (henceforth the WOS) which is (...) generated by their choice of principles of justice. (2) The OP is a conscious event among others, integrated (compatibly with the constraints on knowledge and motivation imposed on the parties) into the regular continuity of experience that comprises each of their ongoing constitutes lives. (3) The parties in the OP thus are, and regard themselves as, psychologically continuing persons, partially determined in personality and interests by prior experiences, capable of recollection and regret concerning the past, anticipation and apprehensiveness regarding the future, and so on. Although the continuity thesis as stated above is not at odds with any of the conditions that define the OP, its exegetical validity is a matter for discussion. I shall be concerned to argue that if it is indeed contained in or a consequence of Rawls' theory, then it casts into doubt the capacity of the OP to generate or justify any principles of justice at all. On the other hand, if the continuity thesis is viewed as dispensable and unnecessary to the Rawlsian enterprise, then Rawls is correct in maintaining the irrelevance of the question of personal identity to the construction of his moral theory. In this case, the contract-theoretic, instrumentalist justification for the two principles of justice (henceforth the 2PJ) needs to be supplanted by a modified conception of wide reflective equilibrium. The considerations that form the bulk of this discussion then may be understood as providing a rationale for Rawls' recent revisions in the model of justification on which his theory of justice rests, and for his increasing emphasis on us as moral mediators between the OP and the WOS. Now I want to consider the question of whether or not, given the textual evidence, anything like the continuity thesis is stated or implied by Rawls, and what problems for his theory, if any, turn on a positive or negative answer to this question. -/- .

ABSTRACT: This essay examines and criticizes a set of Kantian objections to Parfit's attempt in Reasons and Persons to connect his theory of personal identity to practical rationality and moral philosophy. Several of Parfit's critics have tried to sever the link he forges between his metaphysical and practical conclusions by invoking the Kantian thought that even if we accept his metaphysical theory of personal identity, we still have good practical grounds for rejecting that theory when (...) deliberating about what to do. The argument between Parfit and his opponents illuminates broader questions about the relationship between our metaphysical beliefs and ourpractical reasons.RÉSUMÉ: Cet article examine et critique un ensemble d'objections kantiennes à la tentative de Parfit, dans Reasons and Persons, d'ajuster sa théorie de l'identité personnelle à la rationalité pratique et à la philosophie morale. Plusieurs des critiques de Parfit ont essayé de rompre le lien qu'il tisse entre ses conclusions métaphysiques et pratiques en évoquant l'idée kantienne selon -laquelle, même si nous acceptons sa théorie métaphysique de l'identité personnelle, il existe cependant de bonnes raisons pratiques de rejeter cette théorie lorsque nous délibérons à propos de ce que nous devons faire. Le débat entre Parfit et ses adversaires nous éclaire sur un questionnement plus large à propos du rapport entre croyance métaphysique et raison pratique. (shrink)

Animalism—the view that the identity across time of individuals like us consists in the persistence of our animal organisms—does poorly at accounting for our identity-related practical concerns. The reason is straightforward: whereas our practical concerns seem to track the identity of psychological creatures—persons—animalism focuses on the identity of human organisms who are not essentially persons. This lack of fit between our practical concerns and animalism has been taken to reduce animalism’s plausibility (relative to psychological (...) criteria of identity). In this paper, I survey the three leading replies to this challenge, finding them either implausible or incomplete. I will then attempt to construct the only viable response, one that begins by admitting that our practical concerns actually do not consist in a monolithic set; rather, there are distinctly different types of practical concerns, and while some are clearly grounded on psychological relations, some are actually grounded on others, including animalistic and humanistic relations; furthermore, their actual connection to identity is tenuous at best. What these concerns are, how they divide up, and what they are grounded on in each instance—these are the issues it is my second aim in this paper to take up. (shrink)

The vast advances in biometrics over the past several decades have brought with them a host of pressing concerns. Philosophical scrutiny has already been devoted to many of the relevant ethical and political issues, especially ones arising from matters of privacy, bias, and security in data collection. But philosophers have devoted surprisingly little attention to the relevant metaphysical issues, in particular, ones concerning matters of personal identity. This paper aims to take some initial steps to correct this oversight. (...) After discussing the philosophical problem of personal identity, the ways in which the notion of biometric identity connects with, or fails to connect with, the philosophical notion of personal identity is explored. Though there may be some good reasons to use biometric identity to track personal identity, it is contended that biometric identity is not the same thing as personal identity and thus that biometrics researchers should stop talking as if it were.

This paper has two main aims. The first is to propose a new way of characterizing the problem of personal identity. The second is to show that the metaphysical picture that underlies my proposal has important implications for the 3D/4D debate. I start by spelling out several of the old ways of characterizing the problem of personal identity and saying what I think is wrong with each of them. Next I present and motivate some metaphysical principles concerning property (...) instantiations that underlie my proposal. Then I introduce the new way of characterizing the problem of personal identity that I am recommending, and I show that it avoids the difficulties facing the old ways. I also mention several vexing problems that arise in connection with certain popular views about personal identity, and I argue that if we formulate the problem of personal identity in the way that I am proposing, then each of these problems can be handled fairly easily. Finally, I show that there is an additional benefit to adopting my proposal, namely, that several other important problems facing anyone who endorses a 3D view of persistence (as opposed to the 4D, “temporal parts” view of persistence) can all be resolved in a relatively straightforward..

Christine Korsgaard bases her interpretation of personal identity upon the notion of moral agency and thereby refutes the Reductionist thesis of Derek Parfit. Korsgaard indicates that actions and choices, from the practical standpoint, must be viewed as having agents and choosers. This is what makes them our own actions and choices as well as contributes to the process of self-constitution. Personal identity manifested as the chooser of our desires and author of our actions can be viewed as (...) the common denominator between Korsgaard and Wang Yangming (王陽明). For liangzhi (良知) is none other than the agency that acts as the capacity for moral judgment and the motivation of performing moral actions. Given liangzhi is the authentic self that make laws for us, our true identities are exhibited in the performance of moral behaviors. Moreover, further engagement between the two sides reveals that Wang’s characterizations of liangzhi, particularly those of practical justification, law-embodying identity, and zhih –zhi (致知), can be seen as either a complement to practical standpoint argument or an approach of consummating self-constitution.

Eric Olson and David Shoemaker argue that our numerical identity over time is irrelevant to such practical issues as moral responsibility or self-concern. Being the same individual at different moments in time may, in our case, can be seen as the preservation of the relevant biological processes (e.g., according to Olson), while psychological continuity, independent of these processes, may be crucial for such issues. I will defend the view that, contrary to the above authors, any conception of our diachronic (...) identity has ethical implications, at least with regard to the aforementioned issues. My argument has two basic assumptions. (1) The dispute over identity of persons is a dispute over the conditions of our persistence in time as the same individuals, whether we consider being a person as our essential property or not (e.g., Olson maintains the latter). The question is under what conditions I am the same as a particular earlier or later individual. (2) The pronoun “I,” on the other hand, is an essential component of practical reasoning, so also of ethical one. Thus, the debate on the persistence of persons concerns the identity conditions of the individuals to whom/which we refer when planning our future actions, formulating our intentions. My rational self-concern or my moral responsibility for past actions regards the individual to whom the pronoun refers. An additional result of my argument is to undermine the influential strategy of defending positions on our diachronic identity against the charge of controversial ethical implications. It cannot be argued in the case of every such controversy that a given ethical issue only apparently involves our identity, while in fact what is relevant to it is a different relation binding persons at different moments in time.

This paper examines Charles Taylor’s claim that personal identity is a matter of strong evaluations. Strong evaluations are in this paper analyzed as stable preferences, which are strongly identified with and which are based on qualitative distinctions concerning the non-instrumental value of options. In discussing the role of strong evaluations in personal identity, the focus is on "self-identity", not on the criteria of personhood or on the logical relation of identity. Two senses of self-identity can be distinguished: identity (...) as practical orientation and identity as self-definition in a more encompassing sense. The former consists of one’s strong evaluations only, the latter is a more comprehensive notion, in which strong evaluations have a double role. Strong evaluations are first of all directly a constituent of self-definitions, and secondly, self-definition with respect to other features proceeds in the light of the strong evaluations. (shrink)

David Hume’s thought has interrupted entire disciplines from dogmatic slumbers. Yet Hume’s influence is even more expansive and continuous than we might have thought. There are two significant areas of inquiry where Hume’s influence has not been adequately appreciated or articulated: analytic phenomenology and analytic process philosophy. My dissertation explores these traditions’ indebtedness to Hume by engaging with the work of Edmund Husserl and Alfred North Whitehead, who introduce consequential changes into their systems in direct response to what they see (...) as Humean problems with their initial models. Three major themes are of special interest. First, vis-à-vis “Unity of Mind,” each philosopher asks what accounts for the apparent unity of mind and experience, including what principles connect distinct experiences. Second, vis-à-vis “Temporal Awareness,” each philosopher inquires into what grounds temporality and the experience of temporal passage, including what principles connect distinct moments. Third, vis-à-vis “Personal Identity,” each philosopher investigates what constitutes the experience of continuity and unity over time, including personal continuity and unity qua “personal identity.” A fourth concordance is methodological. In pursuing the aforementioned themes, each philosopher accords epistemic primacy to lived experience and what discloses itself therein. An overarching Humean problem for all, correlatively, is how continuity and unity arise from distinct items: perceptions, intentional experiences, and actual occasions, respectively. My dissertation attempts to explicate this and related systematic issues from a historical perspective informed by contemporary analytic metaphysics, philosophy of mind, and recent scholarship in Hume, Husserl, and Whitehead studies. Chapter One argues that Hume’s infamous “Appendix problem” concerns reconciling the incontrovertible unity of mind with his unrenounceable epistemological principle that the mind never perceives real connections between distinct perceptions. Chapter Two traces Hume’s proto-phenomenological influence on Husserl’s theories (not theory) of temporal awareness. Chapter Three examines Hume’s proto-processual influence on Whitehead's theories (not theory) of personal identity. Unfortunately, neither Husserl nor Whitehead read each other’s work. Nevertheless, both take Hume to be the one who knocks at, yet ultimately fails to walk through the doors that his explorations unveil. By so doing, they beg that we do the same with them. (shrink)

Organ transplantation centers set criteria for candidate qualification, which has led to disparate healthcare resource allocation practices affecting those with a substance use history. These individuals are denied organ transplants by committees and healthcare providers who assign them lower priority status. The lower priority argument claims that healthcare resources should not be provided equally to individuals who fail to share responsibility for not doing enough to address the diseases associated with substance use. The purpose of this paper is to explore (...) the interrelatedness between the ethics of a merit-based system of moral responsibility and the lower priority setting involved in healthcare resource allocation pertaining to those with substance use histories. An interdisciplinary approach to the argument against the lower prioritists is taken with a focus on the relationship between different organ allocation practices affecting substance users and the justification for resource allocation practices of healthcare and transplant committees. Lower priority setting is challenged, and an argument is offered in which substance users are assigned higher priority when relying on "doing enough" in a merit-based system of moral responsibility. It is determined that one cannot substantiate assigning a lower priority status since a lack of success in rehab does not imply a lack of effort. Additionally, neither to confirmatory behavior nor to non-conforming behavior may freedom be justifiably ascribed in a merit-based system of responsibility because freedom to choose can neither be established a priori nor a posteriori concerning meritorious behavior.

In this paper, I provide an analysis of Marya Schechtman's theory of personal identity defended in her book Staying Alive: Personal Identity, Practical Concerns, and the Unity of a Life.

This Element offers the first detailed study of Catharine Trotter Cockburn's philosophy and covers her contributions to philosophical debates in epistemology, metaphysics, moral philosophy, and philosophy of religion. It examines not only Cockburn's view that sensation and reflection are the sources of knowledge, but also how she draws attention to the limitations of human understanding and how she approaches metaphysical debates through this lens. In the area of moral philosophy, this Element argues that it is helpful to take seriously Cockburn's (...) distinction between questions concerning the metaphysical foundation of morality and questions concerning the practice of morality. Moreover, this Element examines Cockburn's religious views and considers her understanding of the relation between morality and religion and her religious views concerning the resurrection and the afterlife.

Saul Goodman, Slipping Jimmy, Charlie Hustle, Gene Takavic, Viktor Saint Claire, and many others — all seem to be aliases of one James McGill. The characterization question, from the point of view of the metaphysics of identity, is trying to answer what determines personal identity. The notion of persistence describes necessary and sufficient conditions for a person to continue or cease to exist as a person. The practical importance of persistence includes both responsibility for a person's actions and (...) the fact that identity matters practically because of a person's selfish care about his or her own future. From a Better Call Saul perspective, we are combining metaphysical issues of identity — that pinpoint what it takes for someone to remain the same person — with the pendulum of various James McGill personae. -/- James McGill does seem to have both biological and psychological continuity while shifting from one character to another, but we will argue that psychological continuity is only relevant at the lowest level and that the narrativist account seems to better explain different Jimmy personae. Narrativism answers the persistence question by stating that we are persisting as the same person because of the stories we tell about ourselves, which influence our lives and our decisions. Identity is being constituted at a narrative level, that is — Jimmy is his (current) story, determining when he begins and ends. In this paper, by analyzing character development throughout the series, we are trying to show that James McGill may not always be equated with his aliases because of different spatial and temporal narratives, which also could open various ethical implications of responsibility for past actions.

In her book Experience Embodied Anik Waldow devotes a chapter to “Locke’s Experimental Persons.” Her chapter aims to show how Locke’s views on persons, personal identity, and moral agency in his Essay concerning Human Understanding build on his esteem-based approach to education that he develops in Some Thoughts concerning Education. After outlining main contributions that Waldow makes in her chapter, I turn to three issues that in my view deserve further consideration. First, I draw attention to the question of (...) how Locke’s esteem-based education can be reconciled with his moral views in the Essay. I propose that the question of how children become persons or moral agents who see their actions bound by divine law is worth examining with more detail. Second, I contrast Waldow’s interpretation of what a Lockean action is with an alternative interpretation and show that this has implications for how we understand the role of consciousness in Locke’s account of persons and personal identity. Third, I take a closer look at Waldow’s view that consciousness has an epistemic function in Locke’s account of persons and personal identity and highlight advantages of also acknowledging a metaphysical function of consciousness.

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.

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 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)

Personal identity is one of the important and complex issues in the field of the philosophy of the soul. It is also related to the philosophy of ethics and metaphysics in different respects and has given rise to some problems in these two areas. The justification of ethical responsibility and man's eternity in the posthumous state have attracted psychologist-philosophers' attention to the significance and necessity of explaining personal identity. This paper examines the issue from the view point of (...) Mulla Sadra. Here, the writer initially refers to some of the most important contemporary theories about personal identity which can generally be divided into two reductionist and non-reductionist branches. Reductionists intend to reduce the human identity to elements such as memory, biological specifications, or continuous psychological states, while non-reductionists are against this. Mulla Sadra's theory in this regard is not in conformity with any of the above theories; however, it is more consistent with the non-reductionist approach from certain aspects. Though relying on the fundamental ontological and psychological principles of his own philosophy, Mulla Sadra tries to present a picture of human identity that, while depending on human nature, reveals personal identity, too. This is an identity in whose process of formation the three elements of habits, intentions, and acts play major roles. The extent of the consistency of these three elements with rationality is the reason behind having people with different identities. It should also be added that no human being enjoys a single and fixed identity; rather, identity is a continuous reality that, while being one, is a plural truth. (shrink)

In this paper I discuss a set of problems concerning the method of cases as it is used in applied ethics and in the metaphysical debate about personal identity. These problems stem from research in social psychology concerning our access to the data with which the method operates. I argue that the issues facing ethics are more worrying than those facing metaphysics.

The article focuses on one of the identity-related practical concerns discussed in contemporary debate on personal identity, namely self-concern. The dominant view seems to be that people’s concern for their future selves is preconditioned by their ability to anticipate the experiences of their future selves and that, as a result, a psychological theory of personal identity is required to justify self-concern. I argue that self-concern in its most general form is not preconditioned by the possibility of (...) anticipation. I provide examples showing that people may legitimately be concerned for their future selves even if those selves are unconscious or dead, that is, in states that the people cannot anticipate. I contend that self-concern is not rooted in our desire to have positive experiences, but in our desire to live meaningful lives. Since the value of our lives can be influenced by events that only take place after we cease to exist, I further argue that certain posthumous states of affairs relevant to our lives can also be the legitimate target of an indirect sort of self-concern. Inspired by Marya Schechtman’s theories, I develop a form of the narrative theory of personal identity in the sense of characterization and show that narrative continuity can be both a source of meaning in a person’s life and a ground for the person’s self-concern. It turns out that the sort of identity that justifies non-anticipatory self-concern cannot be numerical identity, because it does not provide the persistence conditions of people. (shrink)

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.

Ruth Boeker offers a new perspective on Locke’s account of persons and personal identity by considering it within the context of his broader philosophical project and the philosophical debates of his day. Her interpretation emphasizes the importance of the moral and religious dimensions of his view. By taking seriously Locke’s general approach to questions of identity, Boeker shows that we should consider his account of personhood separately from his account of personal identity over time. On this basis, she (...) argues that Locke endorses a moral account of personhood, according to which persons are subjects of accountability, and that his particular thinking about moral accountability explains why he regards sameness of consciousness as necessary for personal identity over time. In contrast to some Neo-Lockean views about personal identity, Boeker argues that Locke’s account of personal identity is not psychological per se, but rather his underlying moral, religious, metaphysical, and epistemic background beliefs are relevant for understanding why he argues for a consciousness-based account of personal identity. Taking his underlying background beliefs into consideration not only sheds light on why many of his early critics do not adopt Locke’s view, but also shows why his view cannot be as easily dismissed as some of his critics assume. -/- .

Despite its central role in his important theories of self and external world, Hume’s account of numerical identity has been neglected or misunderstood. The account is designed as a response to a difficulty concerning identity apparently original with Hume. I argue that the problem is real, crucial, and remains unresolved today. Hume’s response to the difficulty enlists his idiosyncratic, empiricist views on time: time consists of discrete, partless moments, some of which coexist with successions of others. Time is more like (...) a wall of variously sized bricks than like a continuous line. Hume’s arguments that time (and space) are not infinitely divisible have met with literal contempt. I show that his unusual views are motivated and consistent. The topic of identity leads naturally to Hume’s account of personal identity and his later retraction--one of the most widely discussed topics in Hume scholarship. I give a new, straightforward explanation of the retraction, by arguing that Hume’s views on consciousness preclude his prior account of the self as a fiction. I then suggest that Hume’s fundamental problem for personal identity is his general difficulty concerning identity. Discussing Hume’s metaphysics raises perhaps the most central and difficult topic in Hume scholarship--how to reconcile the constructive, theoretical Hume with the skeptical Hume. The prevailing view for the last century has been that Hume’s skepticism is limited, leaving room for his theorizing. I argue, rather, that Hume is an unlimited Pyrrhonian skeptic in relevant respects, and that this interpretation of him best reconciles his two sides. (shrink)

Shaftesbury’s major work Characteristicks of Men, Manners, Opinions, Times was one of the most influential English works in the eighteenth century. This paper focuses on his contributions to debates about persons and personal identity and shows that Shaftesbury regards metaphysical questions of personal identity as closely connected with normative questions of character development. I argue that he is willing to accept that persons are substances and that he takes their continued existence for granted. He sees the need to (...) supplement metaphysical debates of personal identity and believes that we have to turn to the character that is realized by a substance if we want to understand who we are. For Shaftesbury persons have a particular character, can act, and govern themselves. I propose that Shaftesbury’s approach to persons has a developmental dimension, which is meant to encourage personal development and improvement of character. The developmental dimension can be understood as an intellectual journey that invites us to search for our true self, to develop our character, and to seek happiness, which ultimately involves understanding our place as persons in the order of the universe. I show that my developmental interpretation is preferable to other existing interpretations. (shrink)

Nancy Jecker and Andrew Ko (2017) wish to present an account of personal identity which captures what matters to the patient and places the patient at the center of medical decisions. They focus particularly on medical interventions in the brain that can cause drastic changes in personality; under what circumstances should we say the patient has 'survived' these changes? More specifically, how can we best understand the notion of survival in a way that captures what is of concern to (...) the patient? This goal is laudable, however, their chosen account of narrative identity is ill-suited to this task for one reason in particular; it does not give sufficient guidance in predicting which medical decisions are likely to be experienced as disruptive to identity.

This is the third chapter of my book Transformation of the self, which covers Schleiermacher's reception of Kant on the problem of personal 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.

Locke’s account of personal identity has been highly influential because of its emphasis on a psychological criterion. The same consciousness is required for being the same person. It is not so clear, however, exactly what Locke meant by ‘consciousness’ or by ‘having the same consciousness’. Interpretations vary: consciousness is seen as identical to memory, as identical to a first personal appropriation of mental states, and as identical to a first personal distinctive experience of the qualitative features of (...) one’s own thinking. There is wide agreement, however, that Locke’s theory of personal identity is meant to complement his moral and theological commitments to a system of divine punishment and reward in an afterlife. But these commitments seem to require also a metaphysical criterion, and Locke is insistent that it cannot be substance. The difficulty reconciling the psychological and metaphysical requirements of the theory has led, at worst, to charges of incoherence and, at best, to a slew of interpretations, none of which is widely accepted.

In this paper, I present an informational approach to the nature of personal identity. In “Plato and the problem of the chariot”, I use Plato’s famous metaphor of the chariot to introduce a specific problem regarding the nature of the self as an informational multiagent system: what keeps the self together as a whole and coherent unity? In “Egology and its two branches” and “Egology as synchronic individualisation”, I outline two branches of the theory of the self: one concerning (...) the individualisation of the self as an entity, the other concerning the identification of such entity. I argue that both presuppose an informational approach, defend the view that the individualisation of the self is logically prior to its identification , and suggest that such individualisation can be provided in informational terms. Hence, in “A reconciling hypothesis: the three membranes model”, I offer an informational individualisation of the self, based on a tripartite model, which can help to solve the problem of the chariot. Once this model of the self is outlined, in “ICTs as technologies of the self” I use it to show how ICTs may be interpreted as technologies of the self. In “The logic of realisation”, I introduce the concept of “realization” (Aristotle’s anagnorisis ) and support the rather Spinozian view according to which, from the perspective of informational structural realism, selves are the final stage in the development of informational structures. The final “Conclusion: from the egology to the ecology of the self” briefly concludes the article with a reference to the purposeful shaping of the self, in a shift from egology to ecology. (shrink)

This paper presents a new anti-criterialist view, Brutal Personal Identity (BPI). According to BPI, personal identity is a quasi-fundamental fact, which is metaphysically grounded in brute facts about absolutely fundamental personhood. By reversing the order of metaphysical explanation, BPI is not a form of identity mysticism as Dean Zimmerman asserts. Instead, BPI has even the potential to lay a solid foundation for developing an appropriate account of mentality and first-person perspectives. Furthermore, a comparison between BPI and soul theory (...) is provided to show why BPI is better than its main anti-criterialist rival. This provides us a compelling reason for considering BPI in the debate over personal identity. (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.

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.

The question of whether or not one should procreate is rarely cast as a personal choice in philosophical discourse; rather, it is presented as an ethical choice made against a backdrop of aggregate concerns. But justifications concerning procreation in popular culture regularly engage with the role that identity plays in making procreative decisions; specifically, how one’s decision will affect who they are and who they might be in the future. Women in particular cite the personally transformative aspects of (...) becoming a parent — personal circumstances, including socioeconomic status, age, health, and relationship status — as the most important considerations for the decision they make regarding possible parenthood, and not the more aggregate concerns that an ethics of procreation prioritizes. I highlight women because when women undergo a transformative experience related to parenthood, they do so in contexts where the social, economic, and emotional effects related to pregnancy and motherhood are extensive and impose greater effects on women than men. These harmful material effects threaten a woman’s economic stability, career development, social relationships, and emotional health. Because of this, I argue that an ethics of procreation must engage with the ways in which women’s identities are transformed through procreative decisions. (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.

Derek Parfit’s early work on the metaphysics of persons has had a vast influence on Western philosophical debates about the nature of personal identity and moral theory. Within the study of Buddhism, it also has sparked a continuous comparative discourse, which seeks to explicate Buddhist philosophical principles in light of Parfit’s conceptual framework. Examining important Parfitian-inspired studies of Buddhist philosophy, this article points out various ways in which a Parfitian lens shaped, often implicitly, contemporary understandings of the anātman doctrine (...) and its relation to Buddhist ethics. I discuss in particular three dominant elements appropriated by Parfitian-inspired scholarship: Parfit’s theoretical categories; philosophical problems raised by his reductionist theory of persons; and Parfit’s argumentative style. I argue that the three elements used in this scholarship constitute different facets of one methodological approach to cross-cultural philosophy, which relies on Western terminology and conceptual schemes to establish a conversation with non-Western philosophy. I suggest that while this methodology is fruitful in many ways, philosophy as a cosmopolitan space may benefit significantly from approaching Buddhist philosophy using its own categories and terminology.

This paper presents a new cognitivist account for the old puzzle of self-consciousness or knowing self-reference. Knowing self-reference does not rely on reflection on some putative pre-existent pre-reflexive self-consciousness, nor is it the result of a process of identification of oneself as the employer of the relevant token of “I” according to the token-reflexive rule of the first-person pronoun. Rather, it relies on the architecture of the cognitive system. By exploiting the acquaintance relation that every brain has to one’s own (...) body, a “mental file” is opened in a subliminal way to house information about oneself gained through the appropriate proprioceptors. Knowing self-reference based on self-files dispenses with self-identification because the opening of the file in the same brain/body is not a deed of the cognitive system but rather something that takes place sub-personally.

Schiller says that “it is only through beauty that man makes his way to freedom.” Here I attempt to defend a claim in the same spirit as Schiller’s but by different means. My thesis is that a person’s autonomous agency depends on their adopting an aesthetic identity. To act, we need to don contingent features of agency, things that structure our practical thought and explain what we do in very general terms but are neither universal nor necessary features of (...) agency as such. Without these things, the question of what to do for any individual would be underdetermined. The problem is that adopting such a contingent form of agency amounts to a restriction on what we can do, and so it is a prima facie threat to our autonomy. I will argue that one way, and indeed the only way, of meeting this challenge lies in aesthetic experience. Granting our capacity for aesthetic pleasure the authority to determine the particularities of our agency is compatible with autonomy because doing so means identifying with one’s capacity for pleasure in free and creative activity. Doing this allows us to be both particular sorts of agents and creatures regulated by the universalizing demands of reason. (shrink)

A popular “Reductionist” account of personal identity unifies person stages into persons in virtue of their psychological continuity with one another. One objection to psychological continuity accounts is that there is more to our personal identity than just mere psychological continuity: there is also an active process of self-interpretation and self-creation. This criticism can be used to motivate a rival account of personal identity that appeals to the notion of a narrative. To the extent that they comment (...) upon the issue, proponents of narrative accounts typically reject Reductionist metaphysics that (ontologically) reduce persons to aggregates of person stages. In contrast to this trend, we seek to develop a narrative account of personal identity from within Reductionist metaphysics: we think person stages are unified into persons in virtue of their narrative continuity with one another. We argue that this Reductionist version of the narrative account avoids some serious problems facing non-Reductionist versions of the narrative account. (shrink)

This is an extension of my earlier work, How in the World Are There Many Worlds and it's a lot more interesting! This paper explores personal identity and persistence through time in the many-worlds framework, governed by the Many Worlds Interpretation (MWI) of quantum mechanics (QM). First, I will motivate our consideration of the MWI in this context. Second, I will introduce endurantism, which is one answer to the puzzle concerning persistence through time. Third, I will explain the foundational (...) physics underlying the MWI that lends itself to branching worlds. In turn, I will explain what exactly a world amounts to in this picture. Then, I will present three views on personal identity and persistence through time: the bye-bye Betty view, the every-branch view, and the privileged branch view. I will argue that the privileged branch view is the most attractive of the bunch for determining the best candidate among close continuers. Finally, I will discuss knowledge, attitudes, and moral responsibility within the privileged branch view. (shrink)

The question of transtemporal identity of objects in general and persons in particular is an important issue in both philosophy and psychology. While the focus of philosophers traditionally was on questions of the nature of identity relation and criteria that allow to settle ontological issues about identity, psychologists are mostly concerned with how people think about identity, and how they track identity of objects and people through time. In this article, we critically engage with widespread use of inferring folk judgments (...) of identity from study participants’ use of proper names in response to experimental vignettes. We provide reasons to doubt that using this method one can reliably infer judgments of numerical identity over time and transformations. We also critically examine allegedly-Kripkean justification of this method and find it lacking. Merely assuming that names are rigid designators will not help. A study participant’s use of proper names can be taken to track the participant’s identity judgments only if supported by the participant’s belief that names used in the scenario are used rigidly.

Hobbes is known for bridging natural and political philosophy, but less attention has been given to how this distinguishes the Hobbesian conception of the self from individualist strands of liberalism. First, Hobbes’s determinism suggests a conception of the self in which externalities determine the will and what the self is at every moment. Second, there is no stable conception of the self because externalities keep it in a constant state of flux. The metaphysical underpinnings of his project downplay the notion (...) of a purely individualistic conception of the self, pointing to a positivist theory of criminology relying upon external forces. This theory is especially prescient with respect to twentieth-century variants of positivism that focus upon how social organization affects personality. In a sense, then, modern criminological theory is indebted to Hobbes’s focus upon the connections between externalities and the self; a focus that illuminates new ways of viewing responsibility and accountability.

I provide a simple solution to the problem of determining the characterising feature(s) of the simple approach to personal identity, sometimes also called the simple view: instead of focusing on claims regarding the analysability, reducibility, or triviality of the concepts used in simple theories of personal identity, I propose instead a metaphysical criterion to define this approach. In particular, I claim that the simple approach is (best seen as) that family of theories according to which personal identity (...) is a relation that essentially depends on a mereologically simple (or impartite) entity the existence and features of which may be known directly (e.g., by introspection) or indirectly (e.g., by deduction from a series of other premises).

The purpose of this article is to introduce, interpret, and develop two incompatible process -ontological theories of personal identity that have received little attention in analytic metaphysics. The first theory derives from the notion of personal identity proposed in Alfred North Whitehead’s philosophy, but I interpret this notion differently from previous commentators. The Whiteheadian theory may appeal to those who believe that personal identity involves an entity or entities that are essentially dynamic, but has nothing to do (...) with diachronic objectual identity : the binary equivalence relation that every entity bears to itself, and only to itself, even after undergoing intrinsic change. The Whiteheadian theory may also find favor with those who, like Whitehead, reject the possibility of pure processes and hold that in every becoming, something—which need not be an object, thing, or individual substance—becomes. The second theory derives from the notion of recurrent dynamics presented in Johanna Seibt’s General Process Theory. The Seibtian theory may appeal to those who believe that personal identity involves not only an entity or entities that are essentially dynamic, but also the relation of diachronic objectual identity. The Seibtian theory may also find favor with those who, like Broad and Sellars, find reason to postulate pure processes. (shrink)

We offer an account of the metaphysics of persons rooted in Latter-day saint scripture that vindicates the essentiality of origins. We then give theological support for the claim that prospects for the success of God’s soul making project are bound up in God creating particular persons. We observe that these persons would not have existed were it not for the occurrence of a variety of evils (of even the worst kinds), and we conclude that Latter-day saint theology has the resources (...) to endorse a strong soul-making non-identity theodicy. We then introduce two complications for this account rooted in the problem of horrendous evils. First, horrendous evils threaten to undermine our confidence that God is good to each created person within the context of their life. And second, horrendous evils raise concerns about the value of persons whose existence depends on the occurrence of those evils. We may wonder whether those whose existence depends on the occurrence of horrendous evils are valuable enough to motivate God’s allowance of those evils. We show that by attending to important structural features of a post-mortem, pre-eschatological state called the spirit world, Latter-day Saints can ameliorate these concerns about horrendous evils .

A main element in Richard Swinburne’s (2019) argument for substance dualism concerns the conditions of a person’s continued existence over time. In this commentary I aim to question two things: first, whether the kind of imaginary cases that Swinburne relies on to make his case should be accorded the kind of weight he supposes; and second, whether philosophers should be concerned to give any substantial theory, of the sort that dualism and its competitors are apparently meant to provide, to (...) explain the conditions of personal identity after all. My suggestion, instead, will be that the concept of a person’s continued existence is better taken as philosophically unanalyzable. (shrink)

In this paper we argue that reflection on the patterns of practical concern that agents like us exhibit strongly suggests that the same person relation comes in continuous degrees rather than being an all or nothing matter. We call this the SP-degree thesis. Though the SP-degree thesis is consistent with a range of views about personal-identity, we argue that combining desire-first approaches to personal-identity with the SP-degree thesis better explains our patterns of practical concern, and hence (...) gives us reason to endorse such an approach. We then argue that the combination of the SP-degree thesis and the desire-first approach are best modelled by a stage-theoretic view of persistence according to which temporal counterpart relations are non-symmetric relations that come in continuous degrees. Ultimately, we think that the overall appeal of this package of views provides reason to accept the package: reasons that outstrip the reasons we have to endorse any particular member of the package.
