In the Treatise Hume argues that a person is “nothing but a bundle of perceptions”. But what precisely is the meaning of this bundle thesis of a person? In my paper, an attempt is made to articulate two plausible interpretations of this controversial view and to identify and evaluate a number of problems for this thesis that is central to Hume’s account of the self.

Personal indexicals are often taken to refer to the agent of an expression’s context, but deviant uses (e.g. ‘I’m parked out back’) complicate matters. I argue that personal indexicals refer to the extended self of the agent, where the extended self is a mereological chimera incorporating whatever determines our behavioral capacities. To ascertain the persistence conditions of personal identity, I propose a method for selecting a level of description and a set of functional properties at that level (...) that remain constant over a lifetime. I argue for functional constancy, and against continuity, as the central determinant of diachronic identity. (shrink)

This paper explores the implications of extended and distributed cognition theory for our notions of personal identity. On an extended and distributed approach to cognition, external information is under certain conditions constitutive of memory. On a narrative approach to personal identity, autobiographical memory is constitutive of our diachronic self. In this paper, I bring these two approaches together and argue that external information can be constitutive of one’s autobiographical memory and thus also of one’s diachronic self. To develop (...) this claim, I draw on recent empirical work in human-computer interaction, looking at lifelogging technologies in both healthcare and everyday contexts. I argue that personal identity can neither be reduced to psychological structures instantiated by the brain nor by biological structures instantiated by the organism, but should be seen as an environmentally-distributed and relational construct. In other words, the complex web of cognitive relations we develop and maintain with other people and technological artifacts partly determines our self. This view has conceptual, methodological, and normative implications: we should broaden our concepts of the self as to include social and artifactual structures, focus on external memory systems in the (empirical) study of personal identity, and not interfere with people’s distributed minds and selves.

The paper discusses Thomas Reid's objection to David Hume's theory of personal identity. The hypothesis states that this criticism is not effective because it is based on a misunderstanding of Hume’s theory, namely, that Hume would have admitted a negative ontological thesis - the inexistence of a mind beyond perceptions - and a positive ontological thesis - a mind reduced to a bundle of perceptions. After explaining in what measures Reid’s objection is based upon this misunderstanding, the paper (...) shows why Hume does not accept those theses,. (shrink)

This paper offers an overview of consciousness and personal identity in eighteenth-century philosophy. Locke introduces the concept of persons as subjects of consciousness who also simultaneously recognize themselves as such subjects. Hume, however, argues that minds are nothing but bundles of perceptions, lacking intrinsic unity at a time or across time. Yet Hume thinks our emotional responses to one another mean that persons in everyday life are defined by their virtues, vices, bodily qualities, property, riches, and the like. Rousseau (...) also takes persons to be fundamentally determined by our socially-mediated emotional responses to one another, though unlike Hume or Locke, he has little interest in placing this account of persons alongside a larger discussion of the human mind and its operations. Developing this idea further, Kant argues that our moral commitments require that we must take ourselves to be free. The fundamental equality that Rousseau sought in the political order is, for Kant, a requirement that reason puts on all of us. (shrink)

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)

I intend to discuss Hume’s theory of personal identity in Books I and II of the Treatise of Human Nature. First, I intend to argue that Hume’s distinction between a ‘personal identity with regard to thought and imagination’ and a ‘personal identity with regard to passions and self-interest’ is only methodological, not radical. That is, the philosopher does not sug-gest the existence of two distinct ideas of personal identity in mind. Secondly, I try to show the (...) contribution of the passions of pride and humility to the production of a belief in personal identity. Pride and humility contribute to the liveliness of this belief by producing the person’s interest in his sensations and actions of the past and the future. Thirdly, I want to show how passions and self-interest make it possible to explain the corporeal aspect of the belief in personal identity. I propose to discuss how the body and its qualities can be understood as constituent elements of the notion of personal identity. (shrink)

This article aims to identify the bundle theory and its influence on the philosophy of mind discussions. The theory was put forward by David Hume, one of the pioneer philosophers of the Enlightenment era, in the context of personal identity. Firstly, a general framework will be drawn about the problem of personal identity. Secondly, it will be explained how the problem is understood in Hume’s epistemology through concepts such as person, identity, self, selfhood. To see the philosophical (...) effects caused by Hume's epistemology, discussions of the philosophy of mind will be exemplified in the existence and knowledge of self through the mindbody understandings of philosophers. Daniel Dennet, John Searle, David Chalmers, and Thomas Metzinger, who have theories about the relationship of self, consciousness, and matter, are the names to be considered under the title of philosophy of mind. Finally, Hume and his theories will be presented with several assessments of the philosophical problems caused by the positions of the aforementioned names on the issue of self. This article aims to reveal the similarities between Hume and philosophers of mind in terms of the existence and knowledge of the self. Except for the evaluation and conclusion section, this article aims to present preliminary work on these approaches. (shrink)

In contemporary Western analytic philosophy, the classic analogical argument explaining our knowledge of other minds has been rejected. But at least three alternative positive theories of our knowledge of the second person have been formulated: the theory-theory, the simulation theory and the theory of direct empathy. After sketching out the problems faced by these accounts of the ego’s access to the contents of the mind of a “second ego”, this paper tries to recreate one argument given by Abhinavagupta (Shaiva philosopher (...) of recognition) to the effect that even in another’s body, one must feel and recognize one’s own self, if one is able to address that embodied person as a “you”. The otherness of You does not take away from its subjectivity. In that sense, just as every second person to whom one could speak is, first, a person, she is also a first person. Even as I regret that I do not know exactly how some other person is feeling right now, I must have some general access to the subjective experience of that other person, for otherwise what is it that I feel so painfully ignorant about? My subjective world is mine only to the extent that I recognize its continuity with a sharable subjective world where other I-s can make a You out of me. (shrink)

The problem of personal identity contains various questions and issues, but the main issue is persistence; how can one person remain the same over time? Modern philosophers have proposed various solutions to this problem; however, none are without problems. David Hume rejected the notion of personal identity as fictitious and posited a theory that personal identity is merely a bundle of perceptions which does not remain the same over time. Hume’s approach to personal identity is (...) flawed, and Derek Parfit pushed back against Hume’s complete rejection of personal identity through his argument of psychological continuity; a continuous chain of overlapping cognitive connections between beliefs, preferences, memories, and other characteristics can meet the criterion of identity. However, Parfit falls short in only acknowledging mental features as the essential property of personal identity; physical features such as age, race, sex, etc. have a significant impact on one’s understanding of themselves. Through a combination of Hume’s bundle theory and Parfit’s psychological continuity, an understanding of what personal identity is and how it is able to remain constant over time can be reached. In this paper, I argue that personal identity is a bundle of mental and physical features that persists through time through psychological continuity. (shrink)

In his magnum opus, David Hume asserts that a person is “nothing but a bundle or collection of different perceptions, which succeed each other with an inconceivable rapidity, and are in a perpetual flux and movement.” (Treatise 252) Hume is clearly proud of his bold thesis, as is borne out by his categorical arguments and analyses on the self. Contributions like this will, in his opinion, help establish a new science of human nature, “which will not be inferior in (...) certainty, and will be much superior in utility to any other of human comprehension.” (Treatise xix) Unfortunately for Hume, the bundle theory of the self subsequently elicits substantial criticism and hostility from numerous critics, both philosophical and non-philosophical. As confident as the young Scot is about the merits of his theory when he first proposes it, the sharp critical responses to his thought on the self ultimately compel him to withdraw his controversial views from public scrutiny. The irony is that the author of the bundle theory of the self himself acknowledges that his account of the self is seriously defective. In his appendix to the Treatise, Hume decries the labyrinth that his views on the self have driven him into. Five years in the making, Hume's Labyrinth: A Search for the Self explores in detail both Hume's views on the self and his critical reservations on an account of the self that would subsequently become highly influential in the philosophy of mind. -/- Central to Hume's Labyrinth is the suggestion that a careful analysis of the appendix to the Treatise throws an invaluable light on a number of elements fundamental to Hume's views on the self, not least of which is the role of Berkeley s views on language. While Hume often acknowledges the significance of Berkeley's philosophy in the Treatise, the argument here is that Berkeley's account of terms is the foundation of Hume's philosophy of the mind, with its contentious bundle theory of the self. And when this influence is assayed a new dimension of Hume's views on the self emerges. For now it appears that the bundle theory of the self is nothing but a heuristic device adopted by Hume to help further philosophical investigations into the mind. In short, it turns out that Hume is a pragmatist, intent on presenting an account of the self that researchers interested in the problems of human nature will find useful. (shrink)

This paper is a tentative step towards a historical cognitive science, in the domain of memory and personal identity. I treat theoretical models of memory in history as specimens of the way cultural norms and artifacts can permeate ('proto')scientific views of inner processes. I apply this analysis to the topic of psychological control over one's own body, brain, and mind. Some metaphors and models for memory and mental representation signal the projection inside of external aids. Overtly at least, medieval (...) and Renaissance theorists agreed that such models had to allow for, or even guarantee, some conception of cognitive order and discipline. Individual memory traces had to be independent, not mixed up or interfering with others. The long tradition of improving or bypassing 'natural memory' by deliberately internalizing artefactual models was part of an arduous process of self-fashioning. Moral panic about confusion and mixture features centrally in the imposition of cognitive discipline in local memory traditions. (shrink)

Self, person, and identity are among the concepts most central to the way humans think about themselves and others. It is often natural in biology to use such concepts; it seems sensible to say, for example, that the job of the immune system is to attack the non-self, but sometimes it attacks the self. But does it make sense to borrow these concepts? Don’t they only pertain to persons, beings with sophisticated minds, and perhaps even souls? I argue that if (...) we focus on the every-day concepts of self and identity, and set aside loftier concepts found in religion, philosophy, and psychology that are applicable, at most, to humans, we can see that self and identity can be sensibly applied widely in biology.

In his Treatise Hume makes a profound suggestion: philosophical problems, especially problems in metaphysics, are verbal. This view is most vigorously articulated and defended in the course of his investigation of the problem of the self, in the section “Of personal identity.” My paper is a critical exploration of Hume's arguments for this influential thesis and an analysis of the context that informs this 1739 version of the nature of philosophical problems that anticipates the linguistic turn in philosophy. -/- (...) .

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.

In this paper, I argue that virtual manifestations of selfhood in VR environments have a transformative effect on the users, which in turn has spillover effects in the physical world. I will argue in favor of extending our notion of personal identity as to include VR avatars as negotiable bodies that constitute a genuine part of who we are. Recent research in VR shows that users can experience the Proteus Effect and other lasting psychological changes after being immersed in (...) VR. An extended theory of the self, modeled after the extended mind thesis advanced by Clark and Chalmers (1998), can offer a deeper understanding of how and why immersive virtual experiences have such a transformative effect on users. The early VR scholars had a similar intuition- that “VR is a medium for the extension of body and mind” (Biocca and Delaney 1995), acting like a genuine “reality engine” (Biocca and Levy 1995).

In exploring personal identity, we are confronted with a perplexing dilemma: What is it in virtue of which a person's younger self is identical to his later self? Personal identity is a significant concept overarching philosophy, psychology, neuroscience, and ethics (Glover, 1988). It provoked debates amongst countless philosophers regarding ideas about human existence, challenging our understanding of self-continuity and selfhood. This essay explores this philosophical problem to better understand ourselves and our interpretations. To build on the foundation of (...) the contrasting insights of philosophers John Locke and David Hume, whose perspectives are examined through concepts of psychological continuity theory, bodily continuity theory, and narrative theory. By shifting the focus on the roots of identity, I reason that the root of a person's identity is their rational nature, defined as the capacity for reason, abstract thought, and self-reflection that mark human beings as persons. If rational nature has been lost, it is only until his social/narrative identity is lost that the person has completely lost their identity. (shrink)

The special and unique attitudes that we take towards events in our futures/pasts—e.g., attitudes like the dread of an impeding pain—create a challenge for “Reductionist” accounts that reduce persons to aggregates of interconnected person stages: if the person stage currently dreading tomorrow’s pain is numerically distinct from the person stage that will actually suffer the pain, what reason could the current person stage have for thinking of that future pain as being his? One reason everyday subjects believe they have a (...) substantially extended temporal existence stems from introspection—they introspectively experience their selves as being temporally extended. In this paper, I examine whether a Reductionist about personal identity can co-opt this explanation. Using Galen Strawson’s recent work on self-experience as a resource, I reach both a negative and a positive conclusion about the prospects of such a position. First, the relevant kind of self-experience—i.e., the introspective experience of one’s self as being a substantially temporally extended entity—will not automatically arise within a person stage simply in virtue of that stage being psychologically connected to/continuous with other person stages. Second, the relevant kind of self-experience will arise, however, in virtue of person stages weaving together their respective experiences, actions, etc. via a narrative. This positive conclusion points towards a new Reductionist position that focuses upon a narrative, and not mere psychological continuity, in attempting to justify the special attitudes we take towards events in our futures/pasts.

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)

Future superintelligent AI will be able to reconstruct a model of the personality of a person who lived in the past based on informational traces. This could be regarded as some form of immortality if this AI also solves the problem of personal identity in a copy-friendly way. A person who is currently alive could invest now in passive self-recording and active self-description to facilitate such reconstruction. In this article, we analyze informational-theoretical relationships between the human mind, its traces, (...) and its future model; based on this analysis, we suggest the instruments to most cost-effectively collect quality data about a person for future resurrection. These guidelines form a “digital immortality protocol”. Digital immortality is plan C for achieving immortality, after plan A, life extension, and plan B, cryonics. (shrink)

In his wide-ranging study of architecture and cultural evolution, Chris Abel argues that, despite progress in sustainable development and design, resistance to changing personal and social identities shaped by a technology-based and energy-hungry culture is impeding efforts to avert drastic climate change. The book traces the roots of that culture to the coevolution of Homo sapiens and technology, from the first use of tools as artificial extensions of the human body to the motorized cities spreading around the world, whose (...) uncontrolled effects are fast changing the planet itself. Advancing a new concept of the meme, called the 'technical meme', as the primary agent of cognitive extension and technical embodiment, Abel proposes a theory of the 'extended self' as a complex and diffuse outcome of that coevolution. Challenging conventional ideas of the self as a separate and autonomous being, the extended self, he explains, encompasses material and spatial as well as psychological and social elements, including the built environment and artifacts, and now reaches out into the virtual world of cyberspace. Drawing upon research into extended cognition and embodied minds from philosophy, psychology and the neurosciences, the book presents a new approach to environmental and cultural studies. N.B.

The book results from several years of work on the problems of consciousness and the self as they are currently posed in the Philosophy of mind and Philosophy of psychiatry. I debate various theories of the self, including those found in contemporary versions of dualism, panpsychism, structuralism, enactivism, and predictive processing, while working towards naturalising the phenomenology of subjectivity.

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)

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.

Deep Brain Stimulation (DBS) is an invasive therapeutic method involving the implantation of electrodes and the electrical stimulation of specific areas of the brain to modulate their activity. DBS brings therapeutic benefits, but can also have adverse side effects. Recently, neuroethicists have recognized that DBS poses a threat to the very fabric of human existence, namely, to the selves of patients. This article provides a review of the neuroethical literature examining this issue, and identifies the crucial dimensions related to the (...) self which DBS may endanger—personal identity, authenticity, and autonomy. The most influential theories accounting for these dimensions are analyzed herein, and it is argued that most of these theories require further refinement. This paper also demonstrates the interrelation between personal identity, authenticity, and autonomy, and concludes that one can only fully understand the impact of DBS on the self when all of these factors are taken into account.

This paper proposes a metaphysical solution to the hard problem of consciousness by presenting a formal theorem that uses set theory and modal logic to demonstrate the equivalence of Being, Self, and the Absolute. Through a series of self-evident axioms and logical propositions it establishes that Being is necessary for all possible entities, Self is necessary for all possible phenomena, and entities imply phenomena while Being implies Self. Furthermore, it posits that there can only be one Absolute, since multiple non-contingent (...) entities lead to a paradox of interdependence; resulting in reductio ad absurdum. Hence, Being, which is Absolute in the objective sense, and Self, which is Absolute in the subjective, are in fact a single Absolute Conscious Being (God). The final postulate takes the form of an imperative which elucidates the Self’s inherent potential for knowledge of itself – commonly mistaken for the individual (body with a mind in a world) – and reveals the path for direct realization of this Absolute Identity. Personal application, cultural integration, and ethical implications are discussed. (shrink)

Hume’s theory of personal identity is developed in response to Locke’s account of personal identity. Yet it is striking that Hume does not emphasize Locke’s distinction between persons and human beings. It seems even more striking that Hume’s account of the self in Books 2 and 3 of the Treatise has less scope for distinguishing persons from human beings than his account in Book 1. This is puzzling, because Locke originally introduced the distinction in order to answer questions (...) of moral accountability and Hume’s discussion of the self in Book 2 provides the foundation of his moral theory in Book 3. In response to the puzzle I show that Locke and Hume hold different moral and religious views and these differences are important to explain why their theories of personal identity differ. (shrink)

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.

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)

Nils-Frederic Wagner takes issue with my argument that influential critics of “transplant” thought experiments make two cardinal mistakes. He responds that the mistakes I identify are not mistakes at all. The mistakes are rather on my part, in that I have not taken into account the conceptual genesis of personhood, that my view of thought experiments is idiosyncratic and possibly self-defeating, and in that I have ignored important empirical evidence about the relationship between brains and minds. I argue that my (...) case still stands and that transplant thought experiments can do damage to rivals of a psychological continuity theory of personal identity like Marya Schechtman’s Person Life View.

Michel Gondry and Charlie Kaufman’s 2004 Eternal Sunshine of the Spotless Mind, which celebrated its fifteenth anniversary in 2019, is an extended thought experiment on the nature of memory, minds, and persons. The memory erasure thought experiment presented in the film—and its implications for personal identity—raises poignant questions for the ethicist, epistemologist, neuroscientist, metaphysician, and cognitive scientist. In this paper, I explore the rich insights the film has to offer interdisciplinary studies of memory, providing a case study in how (...) narrative can uniquely contribute to memory research, while also maintaining philosophical rigor and fidelity to scientific discoveries about memory. Turning to the philosophical implications of memory erasure, I consider memory erasure in the context of several leading views of personal identity and proposed answers to the persistence question of personal identity, assessing the challenges and complications that the memory erasure thought experiment brought to life by Eternal Sunshine poses to these theories. I argue that the psychological continuity view of personal identity—in its various iterations—does not allow an individual to truly survive the memory erasure procedure. The memory erasure thought experiment presented in Eternal Sunshine—and its metaphysical and epistemological consequences—reveal how we establish the relationship between memories and selfhood, how to define personhood in the presence of both hypothetical and real-world memory loss, and what experiences we value in human life.

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.

This paper introduces three new criteria that a theory of personal identity ought to satisfy: (1) material holism, (2) narrative unity, and (3) narrative integrity. Material holism guards against the undesirable consequence of positing the person as part and existentially distinct from the organismal whole, of which it is dependent and interconnected. Narrative unity ensures that continuity between the beginning, middle, and end of a human life is sufficiently accounted for. Narrative integrity secures fidelity and congruence between each part (...) and the whole, the whole to each part. Jeff McMahan’s Embodied Mind Account (EM) fails to satisfy each of these. On McMahan’s account, human persons and human organisms are distinct entities, human persons come into existence after its human organism, and human persons may go out of existence before their human organism. Moreover, fetuses, infants, the congenitally severely cognitively impaired, those with severe dementia, and the comatose are non-persons. A theory of personal identity that incorporates holism and narrative can provide a better explanation of human existence, life and death, and the identity paradox of dicephalic twins. If accepted, EM must either be rejected or ameliorated, and the new criteria ought to be incorporated in contemporary research of personal identity. (shrink)

This article examines the Buddhist idea of anātman, ‘no- self ’ and pudgala, ‘the person’ in relation to the notion of ‘self ’ emerging from contemporary cognitive science. The Buddhist no-self doctrine is enriched by the cognitive scientist’s understanding of the multiple facets of selfhood, or structures of experience, and the causative action of a functional self in the world. A proper understanding of the Buddhist concepts of anātman and pudgala proves critical to mindfulness-based therapeutic interventions: this is as the (...) ‘person’, as constituted by various structures of selfhood, including—the ecological, interpersonal, extended, private, narrative, relational and conceptual selves—which may be disrupted by traumatic events which disorder one’s experience of time, defence, relationality, memory, resource and agency. In the absence of this understanding, the no-self doctrine might encourage a sort of bypass, in which traumatic facets of selfhood are overlooked in the quest for spiritual liberation. With a proper understanding of the function served by the Buddhist concepts of no-self and ‘person’, psychotherapeutic work may be situated as a necessary ‘preliminary practice’ for meditative exploration of deeper transpersonal domains and soteriological goals.

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)

Tobias-Renstrøm and Køppe (2020) show the several conceptual limits that new materialism and postmodern subject models have for psychological theory and research. The present study continues in this discussion and argues that the applicability of the ideas of quantum-inspired new materialism depends on the theoretical perspectives that we consider for analysis: be it the first-person perspective referring to the subjective experience of a human subject, or the third-person perspective, in which a human subject is observed by an external observer. While (...) the arguments of new materialism are in accordance with the analysis of the act of observation performed by an external observer, some problems arise when trying to theoretically approach the first-person subjective experience of a human subject. For example, new materialism fails to explain why human minds can maintain the awareness of a subject’s identity throughout their lives and to recall the memories about their past personal experiences.

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

Memory of past episodes provides a sense of personal identity — the sense that I am the same person as someone in the past. We present a neurological case study of a patient who has accurate memories of scenes from his past, but for whom the memories lack the sense of mineness. On the basis of this case study, we propose that the sense of identity derives from two components, one delivering the content of the memory and the other (...) generating the sense of mineness. We argue that this new model of the sense of identity has implications for debates about quasi-memory. In addition, articulating the components of the sense of identity promises to bear on the extent to which this sense of identity provides evidence of personal identity. (shrink)

In this paper, we propose a mathematical model of subjective experience in terms of classes of hierarchical geometries of representations (“n-awareness”). We first outline a general framework by recalling concepts from higher category theory, homotopy theory, and the theory of (infinity,1)-topoi. We then state three conjectures that enrich this framework. We first propose that the (infinity,1)-category of a geometric structure known as perfectoid diamond is an (infinity,1)-topos. In order to construct a topology on the (infinity,1)-category of diamonds we then propose (...) that topological localization, in the sense of Grothendieck-Rezk-Lurie (infinity,1)-topoi, extends to the (infinity,1)-category of diamonds. We provide a small-scale model using triangulated categories. Finally, our meta-model takes the form of Efimov K-theory of the (infinity,1)-category of perfectoid diamonds, which illustrates structural equivalences between the category of diamonds and subjective experience (i.e.its privacy, self-containedness, and self-reflexivity). Based on this, we investigate implications of the model. We posit a grammar (“n-declension”) for a novel language to express n-awareness, accompanied by a new temporal scheme (“n-time”). Our framework allows us to revisit old problems in the philosophy of time: how is change possible and what do we mean by simultaneity and coincidence? We also examine the notion of “self” within our framework. A new model of personal identity is introduced which resembles a categorical version of the “bundle theory”: selves are not substances in which properties inhere but (weakly) persistent moduli spaces in the K-theory of perfectoid diamonds.

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)

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.

Our ability to tell stories about ourselves has captivated many theorists, and some have taken these developments for an opportunity to answer long-standing questions about the nature of personhood. In this essay I employ two skeptical arguments to show that this move was a mistake. The first argument rests on the observation that storytelling is revisionary. The second implies that our stories about ourselves are biased in regard to our existing self-image. These arguments undercut narrative theories of identity, but they (...) leave room for a theory of narrative self-knowledge. The theory accommodates the first skeptical argument because there are event descriptions with retrospective assertibility conditions, and it accommodates the second argument by denying us epistemic privilege in regard to our own past. The result is that we do know our past through storytelling, but that it is a contingent feature of some of our stories that they are about ourselves. (shrink)

I am Me and not someone else. This might just be a spur of the moment type of statement; however, it weighs more than it seems. Moreover, it delves into an individual’s understanding of the self-amidst different factors revolving one’s identity. Personal identity can be deemed as a puzzle of distinct characteristics, experiences, understanding, and values in which when put together define who a person is. It involves different aspects in life such as self-perception, cultural background, beliefs, traditions, and (...) even societal roles, which contribute bit by bit on how individuals view themselves and are perceived by others. Identity and sameness over time are related to one another. Understanding sameness over time—how a person remains essentially “the same” amidst changes in physical appearance, experiences and, or beliefs—remains significant as it helps maintain a rational sense of the self. The continuity of the interplay of changes in different aspects of an individual’s self is essential in fostering self-awareness, personal growth, and formation of stable relationship among others. This also underpins moral and legal accountability to ensure that individuals are treated as themselves throughout time. What constitutes the “self” that remains the same person over time, despite changes in experiences, physical form, and beliefs? This paper aims to explore major theories of identity and argue for the most coherent view or propose an integrated approach. (shrink)

The aims of this paper are to: (1) identify the best framework for comprehending multidimensional impact of deep brain stimulation on the self; (2) identify weaknesses of this framework; (3) propose refinements to it; (4) in pursuing (3), show why and how this framework should be extended with additional moral aspects and demonstrate their interrelations; (5) define how moral aspects relate to the framework; (6) show the potential consequences of including moral aspects on evaluating DBS’s impact on patients’ selves. Regarding (...) (1), I argue that the pattern theory of self can be regarded as such a framework. In realizing (2) and (3), I indicate that most relevant issues concerning PTS that require resolutions are ontological issues, including the persistence question, the “specificity problem”, and finding lacking relevant aspects of the self. In realizing (4), I identify aspects of the self not included in PTS which are desperately needed to investigate the full range of potentially relevant DBS-induced changes—authenticity, autonomy, and responsibility, and conclude that how we define authenticity will have implications for our concept of autonomy, which in turn will determine how we think about responsibility. Concerning (5), I discuss a complex relation between moral aspects and PTS—on one hand, they serve as the lens through which a particular self-pattern can be evaluated; on the other, they are, themselves, products of dynamical interactions of various self-aspects. Finally, I discuss (6), demonstrating novel way of understanding the effects of DBS on patients’ selves. (shrink)

The acquisition of virtue can be conceptualized as a self-regulatory process in which deliberate practice results in increasingly higher levels of skillfulness in leading a virtuous life. This conceptualization resonates with philosophical virtue theories as much as it converges with psychological models about skill development, expertise, goal motivation, and self-regulation. Yet, the conceptualization of virtue as skill acquisition poses the crucial question of motivation: What motivates individuals to self-improvement over time so that they can learn from past experience, correct mistakes, (...) and expand their ethical knowledge to new and unfamiliar circumstances? In this paper, it is argued that the motivation to increase one’s level of skillfulness in leading a virtuous life is supported by a specific identity goal, namely the goal to be a moral person. However, this moral identity goal needs to carry specific goal characteristics in order to effectively provide this motivation. It needs to be sufficiently abstract, internally motivated and promotion- rather than prevention-oriented. Research in developmental psychology suggests that the moral identity of children is rather concrete, externally motivated, and prevention-oriented. With development, higher levels of abstraction, internal motivation, and promotion-orientation gain importance providing an important motivational basis for a self-regulated process of virtue acquisition.

This paper proposes a new explanation for the paradoxes related to anthropic reasoning. Solutions to the Sleeping Beauty Problem and the Doomsday argument are discussed in detail. The main argument can be summarized as follows: -/- Our thoughts, reasonings and narratives inherently comes from a certain perspective. With each perspective there is a center, or using the term broadly, a self. The natural first-person perspective is most primitive. However we can also think and express from others’ perspectives with a theory (...) of mind. A perspective’s center could be unrelated to the topic of discussion so its de se thoughts need not to be considered, e.g. the perspective of an outside observer. Let’s call these the third-person perspective. First-person reasoning allows primitive self identification as I am inherently unique as the center of the perspective. Whereas from third-person perspective I am not fundamentally special comparing to others so a reference class of observers including me can be defined. It is my contention that reasonings from different perspectives should not mix. Otherwise it could lead to paradoxes even independent of anthropic reasoning. The paradoxes surrounding anthropic reasoning are caused by the aforementioned perspective mix. Regarding the sleeping beauty problem the correct answer should be double halving. Lewisian halving and thirding uses unique reasonings from both first and third-person perspectives. Indexical probabilities such as “the probability that this is the first awakening” or “the probability of me being one of the first 100 billion human beings” also mixes first- and third-person reasonings. Therefore invalid. Readers against perspectivism may disagree with point 1 and suggest we could reason in objective terms without the limit of perspectives. My argument is compatible with this belief. Objective reasoning would be analytically identical to the third-person perspective. My argument would become that objective reasoning and perspective reasonings should not mix. In the following I would continue to use “third-person perspective” but readers can switch that to “objective reasoning” if they wish so. (shrink)

One of the topics in the philosophy of mind is the discussion of "I", which philosophers have referred to in various interpretations as "The self", "personal identity", "ego", "soul" and "spirit". Philosophers' different theories about the existence and even the nature of this seemingly simple and obvious have turned it into a philosophical problem. Galen Strawson is a physicalist who has addressed this issue by interpreting “The self”. On the one hand, he believes in the existence of the "empirical (...) self", but on the other hand, he denies such qualities as Long-term persistence, personality, and agency, which seem to be essential to the meaning of the "I". The present paper tries to address, by an analythical-critical method, the question of how Strawson believed in the existence of the "I" despite the non-acceptance of these three characteristics. In this regard, first Strawson's view on the nature and existence of the "I" is analyzed, and after evaluating his view, it is concluded that the elimination of these three characteristics is due to weaknesses such as adopting a physicalist basis, a phenomenological method, and a purely mental view of the "I", confusion of the two positions of Truth and proof and his weakness in explaining the nature of unity over time.

Can a person from Latin America be a Catholic, or a feminist, or a democratic socialist in an authentic way? These identities come from Europe, and given the colonial history of Latin America, it seems reasonable to think that decolonizing the Latin American mind is a condition for its authenticity. Further, it seems reasonable to think that decolonization itself requires extirpating ideas and identities originating from the colonizers, especially those used to establish the colonial order. Thus, it seems that Latin (...) Americans cannot adopt such identities; authentic decolonization demands otherwise. In this paper I argue that the thought of twentieth century Mexican philosopher Jorge Portilla provides a persuasive account of the nature of authentic self-creation that allows for a kind of decolonization that makes it conceptually possible for Latin Americans to be Catholics, feminists, or democratic socialists in an authentic fashion. That is, authentic decolonization of the mind, I argue, need not involve a blanket rejection of identities originating from the colonizers; instead, it can be understood as a particular kind of authentic self-creation: one that is appropriately sensitive to the colonial history of the identities freely chosen by the agent.

In this paper I argue for a novel interpretation of Shepherd’s notion of selfhood. In distinction to Deborah Boyle’s interpretation, I contend that Shepherd differentiates between the mind and the self. The latter, for Shepherd, is an effect arising from causal interactions between mind and body – specifically those interactions that give rise to our present stream of consciousness, our memories, and that can unite these two. Thus, the body plays a constitutive role in the formation of the self. The (...) upshot of this interpretation is that it can dissolve the problem of individuating mind that Boyle identifies. Briefly, the problem consists in Shepherd seemingly individuating minds in terms of their associated bodies and bodies in terms of the minds they are united with. My interpretation, however, allows to see that Shepherd neither wants nor needs to individuate the mind in isolation of the body and to read the passages, in which the problem seems to arise, as being about what makes living beings individual – with mind and body both playing a crucial role in this context.

In this paper, I present a two-pronged argument devoted to defending the type-identity theory of mind against the argument presented by Kripke in _Naming and Necessity_. In the first part, the interpersonal case, I show that since it is not possible to establish the metaphysical conditions for phenomenal identity, it is not possible to argue that there can be physical differences between two subjects despite their phenomenal identity. In the second part, the intrapersonal case, I consider the possibility of imagining (...) one and the same individual having the same phenomenal state while counterfactually being in very different physical states. I argue that this case should respect Kripke’s implicit theory of personal identity—but this proves to be a very difficult task to accomplish, thus preventing the argument from getting off the ground. Therefore, I maintain, that the type-identity theory is still the better option to solve the mind–body problem. (shrink)
