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)

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)

Enlightenment values are built around the presumption of an independent rational self, citizen, consumer and pursuer of self-interest. Even the authoritarian and communitarian variants of the Enlightenment presumed the existence of autonomous individuals, simply arguing for greater weight to be given to their collective interests. Since Hume, however, radical Enlightenment empiricists have called into question the existence of a discrete, persistent self. Today neuroscientific reductionism has contributed to the rejection of an essentialist model of personal identity. Contemporary (...) transhumanism has yet to grapple with the radical consequences of the erosion of liberal individualism on their projects of individually chosen enhancement and longevity. Most transhumanists still reflect an essentialist idea of personal identity, even as they embrace projects of radical cognitive enhancement that would change every constituent element of consciousness. Transhumanists need to grapple with how their projects and ethics would change if personal identity is an arbitrary, malleable fiction. (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)

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)

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)

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)

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)

I am going to defend a diagnosis of Hume’s recantation that I have already defended—rather unsuccessfully—in more than one publication. My excuse for trying again is that I shall now offer a more carefully qualified defense. My diagnosis was, and still is, that in the Appendix to the Treatise Hume came to see that he could not account for the necessary ownership of perceptions —i.e., for the fact that this very perception could not have occurred in a different (...) set. (shrink)

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)

The paper aims to present two distinct ways of defending John Locke’s theory of personal identity from Thomas Reid’s objection. First, it will be argued that this objection is not effective since it starts from a misunderstanding of Locke’s theory. The identity of a person is not preserved by the psychological continuity of consciousness, as Reid understood it, but by its ontological continuity: the existence of the same consciousness preserves the personal identity. Secondly, it will (...) be argued that it is possible to reply to that objection in the light of the observation that the personal identity is preserved by the identity of the man: person and man are connected by means of the notion of body.

This book provides the first comprehensive account of Hume’s conception of objects in Book I of the Treatise. What, according to Hume, are objects? Ideas? Impressions? Mind-independent objects? All three? None of the above? Through a close textual analysis, I show that Hume thought that objects are imagined ideas. However, I argue that he struggled with two accounts of how and when we imagine such ideas. On the one hand, Hume believed that we always and universally (...) imagine that objects are the causes of our perceptions. On the other hand, he thought that we only imagine such causes when we reach a “philosophical” level of thought. This tension manifests itself in Hume’s account of personal identity; a tension that, I argue, Hume acknowledges in the Appendix to the Treatise. As a result of presenting a detailed account of Hume’s conception of objects, we are forced to accommodate new interpretations of, at least, Hume’s notions of belief, personal identity, justification and causality. (shrink)

This essay gives a new interpretation of Hume's second thoughts about minds in the Appendix, based on a new interpretation of his view of composition. In Book 1 of the Treatise, Hume argued that, as far as we can conceive it, a mind is a whole composed by all its perceptions. But—this essay argues—he also held that several perceptions form a whole only if the mind to which they belong supplies a “connexion” among them. In order to do (...) so, it must contain a further perception or perceptions. But when the perceptions in question are all of those belonging to a given mind—as in the section “Of personal identity” and the Appendix—there cannot be a further perception in that mind, and so those perceptions do not form a whole. Hence, Hume's views were inconsistent. This essay argues that, unlike most others, this interpretation explains his retreat to skepticism in the Appendix. (shrink)

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. -/- .

John Locke is often understood as the inaugurator of the modern discussion of personal human identity—a discussion that inevitably falls back on his own theory with its critical reliance on memory. David Hume and Sigmund Freud would later make arguments for what constituted personal identity, both relying, like Locke, on memory, but parting from Locke's company in respect the role that memory played. The purpose of this paper will be to sketch the groundwork for Locke's (...) own theory of personal identity and consider some common objections tied to his special reliance on memory. Then, we will investigate the extent to which Hume and Freud refined their respective concepts of self-identity in ways that escape some of the most intractable objections to Locke's theory in its dependence on memory. Finally, we will consider which theorist's conception of self-identity best accords with our notion of the cyber-self, or psychological subjectivity in the context of cyberspace. For Locke, the nature of self-identity is that it is continuous across time, and to remain uninterrupted it must be beholden to a psychological process, rather than a material or immaterial substance.

The following article examines the comparison between the human mind and a Commonwealth proposed by Hume in section 1.4.6 of the Treatise of Human Nature. As the members of a given social society do not link their respective interests by causality relations, such a comparison is not to be understood as an illustration of causality relations between perceptions. We would like to prove that such comparison asserts that our belief in personal identity is stemming from the invention (...) of an artificial reality; showing that only the invention of a rule of stability of possession can legitimate the possession of all objects – may they be goods or perceptions – and sets a criterion enabling to differentiate my perceptions from those of my fellows.

This essay examines the relation between philosophical questions concerning personal identity and character development in Shaftesbury’s and Hume’s philosophy. Shaftesbury combines a metaphysical account of personal identity with a normative approach to character development. By contrasting Shaftesbury’s and Hume’s views on these issues, I examine whether character development presupposes specific metaphysical views about personal identity, and in particular whether it presupposes the continued existence of a substance, as Shaftesbury assumes. I show that (...) Hume’s philosophy offers at least two alternatives. Moreover, I consider whether and how Hume’s philosophy leaves scope for character development and how he departs from Shaftesbury’s normative project of self-formation. (shrink)

Given the difficulty of characterizing the quandary introduced in Hume’s Appendix to the Treatise, coupled with the alleged “underdetermination” of the text, it is striking how few commentators have considered whether Hume addresses and/or redresses the problem after 1740—in the first Enquiry, for example. This is not only unfortunate, but ironic; for, in the Appendix, Hume mentions that more mature reasonings may reconcile whatever contradiction(s) he has in mind. I argue that Hume’s 1746 letter to Lord (...) Kames foreshadows a subtle, but significant, shift in Hume’s reasonings regarding the relevance of “real connexions”; that the Enquiry of 1748 provides evidence for this shift; and that this shift obviates Hume’s second thoughts by reconciling the contradiction that he had in mind. In short, Hume’s letter to Kames and Enquiry supply the retrodictive keys to a systematically satisfactory account. (shrink)

In this paper I explore how and why personal identity might be essentially narrative in nature. My topic is the question of personal identity in the strict sense of identity—the question of which person you are, and how that person is extended in space, time, and quality. In this my question appears to contrast with the question of personal identity in the sense sought by teenagers and sufferers of mid-life crises who are trying (...) to ‘find themselves’. But in fact it will be key to my argument that these questions are not distinct and independent. Whereas Parfit was concerned, in his work on personal identity, with how he was extended over time, the teenager who is finding themselves is concerned with how they are extended in quality. Indeed, the core of my argument is that because narrative is the key to understanding how we are extended in quality, and quality is just one more dimension along which we are extended, along with space and time, narrative must also be the clue as to how we are extended in space and time. You, I will argue, are the protagonist in the best story of your life. (shrink)

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

Hume’s Letter from a Gentleman is an important document for Hume scholarship because, among other things, it serves as a useful tool for the interpretation and analysis of Hume’s philosophical intentions in the Treatise. The Letter itself, however, raises several difficult problems of interpretation. One of the most important of these concerns the identity of Hume’s “accuser“-the author of A Specimen of the Principles concerning Religion and Morality &c., to which Hume is responding in (...) the Letter. Clearly the interpretation of the Letter, and its relevance to the Treatise, will vary depending on who is identified as the source of the accusations against Hume, and what is made of this person’s motivation and philosophical commitments. The immediate difficulty is that the Specimen is presented anonymously, and thus conjectures must be made about the author on the basis of available evidence. (shrink)

Locke is often thought to have introduced the topic of personal identity into philosophy when, in the second edition of theEssay,he distinguished the person from both the human being and the soul. Each of these entities differs from the others with respect to their identity conditions, and so they must be ontologically distinct. In particular, Locke claimed, a person cannot survive total memory loss, although a human being or a soul can.

This paper will argue that Hume's notion of the self in Book 2 of the Treatise seems subject to two constraints. First, it should be a succession of perceptions. Second, it should be durable in virtue of the roles that it plays with regard to pride and humility, as well as to normativity. However, I argue that these two constraints are in tension, since our perceptions are too transient to play these roles. I argue that this notion of self (...) should be characterized as a bundle of dispositions to our perceptions, such that these dispositions are durable and counterfactual-supporting. I argue that Hume confused his ‘philosophical’ notion of dispositions, as nothing above and beyond their effects, with the thicker notion of dispositions to which the passions respond—which explains his mistaken commitment to the durability constraint.

The Scottish philosopher David Hume (1711-1776) is widely regarded as the greatest and most significant English-speaking philosopher and often seen as having had the most influence on the way philosophy is practiced today in the West. His reputation is based not only on the quality of his philosophical thought but also on the breadth and scope of his writings, which ranged over metaphysics, epistemology, morals, politics, religion, and aesthetics. The Handbook's 38 newly commissioned chapters are divided into six parts: (...) Central Themes; Metaphysics and Epistemology; Passion, Morality and Politics; Aesthetics, History, and Economics; Religion; Hume and the Enlightenment; and After Hume. The volume also features an introduction from editor Paul Russell and a chapter on Hume's biography. (shrink)

This essay examines Locke’s chapter “Of Identity and Diversity” (Essay 2.27) in the context of the series of chapters on ideas of relations (Essay 2.25–28) that precede and follow it. I begin by introducing Locke’s account of how we acquire ideas of relations. Next, I consider Locke’s general approach to individuation and identity over time before I show how he applies his general account of identity over time to persons and personal identity. I draw attention (...) to Locke’s claim that “person” is a forensic term and analyse his arguments for why the sameness of a human being and the sameness of a substance or soul are neither necessary nor sufficient for personal identity. Instead, Locke argues that personal identity consists in sameness of consciousness. Locke regards persons as moral agents who are accountable for their actions. If a person now is held accountable for a past action it is important that the person now is the same person as the person who did the action. This means that moral accountability presupposes personal identity. Additionally, it will be important to consider whether the person deserves reward or punishment for the action. Locke’s account of moral relations, which he develops in Essay 2.28, addresses this issue and I show how it supplements his account of persons and personal identity. (shrink)

In this paper I try to understand David Hume’s theory of the ideas as an alternative ontology. I assume that David Hume seeks to establish a criterion of human knowledge and moral behavior by thinking the fundamental concepts from philosophical tradition, such as substance and personal identity or subjectivity, and turning between the denial and the affirmation of them. In this sense, the criticism of the metaphysical tradition, to which some interpreters reduce his theory, and the (...) alternative ontology which we purpose here, have to promote a middle ground between common sense and philosophical meaning of life, truth and morality. In the development of this interpretation the classifi cations perceptions are exposed, being independent existences and the basis of Hume’s epistemology. Subsequently, the elements of an intermittent subjectivity that can be derived from them are exposed. Finally, we consider the figments of the imagination, being the latter, rather than a power of representation among others, a substance between substances. (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)

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

In “Of Personal Identity”, Hume attempts to understand why we ordinarily believe in persistent selves. He proposes that this ontological commitment depends on illusions and fictions: the imagination tricks us into supposing that an unchanging core self remains static through the flux and change of experience. Recent work in cognitive science provides a good deal of support for Hume’s hypothesis that common beliefs about the self are founded on psychological biases rather than rational insight or evidence. (...) We naturally believe in personal persistence, according to this emerging research, because we are prone to categorize the world in terms of hidden essences and structure our lives in terms of whole life stories.

In the appendix to his Treatise Hume admits that his philosophy of mind is defective. Reluctantly he asserts that his thought has ensnared him in a labyrinth. Referring specifically to the section in the Treatise on personal identity and the self, the young Scot admits that he is “involv’d in such a labyrinth, that, I must confess, I neither know how to correct my former opinions, nor how to render them consistent.” (Treatise 633) My paper is a (...) critical investigation of this characterization of Hume’s predicament. I argue (1) that at best Hume is facing a dilemma, not a labyrinth, and (2) that the dilemma can be solved, and (3) that the resolution to Hume’s problem can be found in his conception of intelligibility.

In this paper I explore how Kant’s development of the idea of the disposition in the Religion copes with problems implied by Kant’s idea of transcendental freedom. Since transcendental freedom implies the power of absolutely beginning a state, and therefore of absolutely beginning a series of the consequences of that state, a transcendentally free act is divorced from the preceding state of an agent, and would thus seem to be divorced from the agent’s character as well. The paper is divided (...) into two parts. First I analyze Kant’s understanding of the disposition and discuss the ways in which it allows us to understand a person’s transcendentally free actions in terms of that person’s character. I then discuss Kant’s resources for understanding the Socratic injunction to care for the soul in light of his concept of the disposition. (shrink)

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.

The ancient theory of substance and accident is supposed to make sense of complex unities in a way that respects both their unity and their complexity. On Hume’s view such complex unities are only fictitiously unities. This result follows from his thoroughgoing critique of the theory of substance. I will characterize the theory Hume is critiquing as it is presented in Locke, presupposing what Bennett calls the “Leibnizian interpretation.” Locke uses the word ‘substance’ in two senses. Call substance (...) in the first sense “individual substance” and in the second sense “pure substance.” I will discuss the seven main parts of Hume’s view: (I) that we have no idea of pure substance, (II) that there is no complex individual substance, except in a loose sense, (III) that the fiction of complex individual substance arises in a way parallel to that of the fiction of identity through time, and (IV) results in the fiction of pure substance, (V) that simple qualities and perceptions satisfy the definition of individual substance, (VI) that there is no such thing as inherence, and (VII) that there is no such thing as pure substance. Hume’s views on substance are often mentioned without being discussed in detail. Kemp Smith, Stroud, and Garrett, for example, mostly summarize various claims of Hume in the course of expounding on his theory of the idea of personal identity. In contrast, I will attempt to present a systematic treatment of Hume on substance as a refutation of Locke. (shrink)

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

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

The paper advances the hypothesis that David Hume’s philosophy explains the corporeal dimension of the self, particularly, one’s belief in a body as being ‘her own body’, as a part of one’s self, in light of three different perspectives: through the operations of the imagination, the associative principles and the perception of mental and physical parallel states; through the occurrence of certain passions in the mind, particularly, pride, humility, and self-interest which direct one’s attention to a body that is (...) felt to be her own body; through the consciousness of the ability of the will to guide the power of moving certain parts of the body. Finally, it is argued that the mental phenomenon of belief in one's own body is a mutual construction of the human mind, that is, it is produced simultaneously by intellectual, affective, and volitional operations.

Legal theorists have proposed several theories to justify statutes of limitations in the criminal law, but none of these normative theories is generally accepted. This chapter investigates the related descriptive question as to whether ordinary people have the intuition that legal punishment becomes less appropriate as time passes from the date of the offense and, if they do, what factors play a role in these intuitions. Five studies demonstrate that there is an intuitive statute of limitations on both legal punishment (...) and moral criticism, and that these intuitions arise, in part, from judgments about changes in psychological connectedness over time.

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

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- (...) class='Hi'>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)

Öz David Hume İnsan Doğası Üzerine Bir İnceleme’de ben idesinin bilgikuramsal temellerini araştırırken, bir yandan hiç kuşku duyulmaksızın kabul edilen ben’e ilişkin bilgimizin güvenilir temellere dayanmadığını göstermeye çalışıyor, diğer yandan da bu tür bir araştırmanın ancak bir bilim aracılığıyla yapılması gereğine dikkat çekiyordu. Ben idesi için görgül kanıt arayışı, oluşturmaya çalıştığı insan biliminin deneysel temelleri olması gerektiği gibi insan doğasına ilişkin araştırmalar için yeni bir uslamlamayı da imliyordu. Hume’un önerdiği uslamlama yöntemi, geleneksel felsefenin insan zihnine dair yaklaşımının artık (...) savunulamaz olduğunun bir göstergesidir. Bu yazıda Hume’un ben idesi öğretisini oluştururken, zihinsel etkinlikleri doğal bir süreç içerisinde kalarak açıklama girişimi irdelenecek, ortaya koyduğu kavramsal ve ilkesel yeniliklerin günümüzde bilişsel bilimler olarak tanımlanan alanın doğuşunda etkili olduğu savunulacaktır. Bu amaçla, ben idesinin oluşumundaki bilgi kuramsal temeller, kişi-özdeşliği öğretisine ve bu tür bir özdeşliği düşünmemizi olanaklı kılan belleğin rolüne dikkat çekerek çözümlenecektir. -/- Abstract While Hume investigates the epistemological basis of the idea of self in his book 'A Treatise of Human Nature', on the one hand he tries to show that our knowledge about the self that is accepted without any doubt does not have reliable basis, on the other hand he draws our attention that any research in this field should be conducted through a science. The search for the emprical evidence for the idea of self is both required for the experimental basis of the newly formed human sciences, and implies a new reasoning for the researches concerning the human nature. Hume’s method of reasoning indicates that the approaches of the traditional philosophy concerning human mind are no longer tenable. In this paper it is examined that while Hume establishes the doctrine of the idea of self, he attempts to explain the mental activities remaining in a natural course, and it is argued that Hume’s epoch-making conceptual and principal contributions in this area have an undeniable impact upon the cognitive sciences of our age. Thus, the epistemological basis of the formation of the idea of self will be analysed by drawing our attention to the personal identity and to memory which makes possible to think such an identity.

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.

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.

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)

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)

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.

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 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.

According to Locke, appropriation is a precondition for moral responsibility and thus we can expect that it plays a distinctive role in his theory. Yet it is rare to find an interpretation of Locke’s account of appropriation that does not associate it with serious problems. To make room for a more satisfying understanding of Locke’s account of appropriation we have to analyse why it was so widely misunderstood. The aim of this paper is fourfold: First, I will show that Mackie’s (...) and Winkler’s interpretations that have shaped the subsequent discussion contain serious flaws. Second, I will argue that the so-called appropriation interpretation —that is the view that appropriation is meant to provide alternative persistence conditions for persons—lacks support. Third, I will re-examine Locke’s texts and argue that we can come to a better understanding of his notion of appropriation in the Essay if we interpret it in analogy to his account of appropriation in Two Treatises. Fourth, I will offer a more fine-grained interpretation of the role of appropriation in relation to persistence conditions for persons. I conclude by showing that the advantage of this proposal is that it reconciles interpretations that have commonly been thought to be inconsistent. (shrink)

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