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 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.

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)

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.

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)

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)

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.

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.

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)

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 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)

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)

Apresentaremos neste texto a tese de David Hume sobre a identidade pessoal tal como é apresentada no Tratado da natureza humana, de sua autoria. No apêndice da obra, Hume apresenta dúvidas sobre a tese que defendeu, apontando uma série de problemas que não se resolvem em sua teoria. Mas o tratamento desses problemas e uma possível resposta a Hume podem ser encontrados em D. W. Winnicott.

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.

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.

No Tratado da Natureza Humana David Hume (2009, p. 285-6 / T 1.4.6 (§5)) prescreve que “devemos distinguir a identidade pessoal enquanto diz respeito a nosso pensamento e imaginação, e enquanto diz respeito a nossas paixões ou ao interesse que temos por nós mesmos”. Enquanto o primeiro escopo é por ele abordado em seção específica no Livro I da obra em questão e pode ser sintetizado através da tese de que a atribuição de identidade sincrônica e diacrônica ao eu é (...) imprópria e que o eu não passa de uma coleção ou feixe de percepções, a segunda delimitação é desenvolvida ao longo de todo o Livro II do Tratado, em meio a sua argumentação acerca das emoções, ou paixões, humanas. Uma vez tendo negado ser possível dispor de uma ideia de eu simples em um instante e contínua no transcorrer do tempo, devido à inexistência de qualquer impressão simples e duradoura para sustentá-la, é intrigante que, ao tratar das paixões indiretas, o autor reintroduza a noção de eu, desta vez como objeto do orgulho. Ademais, Hume (2009, p. 285 / T 1.4.6 (§4)) alega haver uma “propensão natural a imaginar essa simplicidade e identidade” do eu. Em que medida essa propensão deve-se não apenas à semelhança, à causalidade e à memória, como defendido no Livro I, mas também às emoções? Questiona-se ainda se há, como defende Rorty (2006), diferentes ideias de eu, uma pressuposta pelo orgulho e outra por este produzida, ou se Hume desenvolve diferentes aspectos de uma única ideia de eu em todo o Tratado, de modo que o eu como feixe de percepções é o mesmo implicado pela simpatia e produzido, enquanto objeto, pelo orgulho e pela humildade, como argumenta Carlson (2010). A fim de lançar luz sobre tais problemas e de compreender como o Livro II complementa os escritos humeanos acerca do eu no Livro I, o presente trabalho está organizado em dois momentos. Primeiramente será apresentado o viés humeano acerca do problema da identidade pessoal a partir da seção 6 da parte 4 do primeiro livro do Tratado, seguido pela apreciação das diferentes interpretações da noção de eu desenvolvida no Livro II.

Many scholars have claimed that the psychology of the indirect passions in the Treatise is meant to capture how we come to regard persons as morally responsible agents. My question is exactly how the indirect passions relate to responsibility. In elucidating Hume’s account of responsibility, scholars have often focused not on the passionate responses themselves, but on their structural features. In this paper, I argue that locating responsibility in the structural features is insufficient to make sense of Hume’s account of (...) responsibility. I argue this on the grounds that without reference to the passions, Hume does not have the resources to distinguish between responsible and non-responsible entities. Instead, I attribute to Hume a distinctive, sympathy-based response-dependent conception of responsibility. (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)

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 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 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)

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.

Hume introduced important innovations concerning the theory of ideas. The two most important are the distinction between impressions and ideas, and the use he made of the principles of association in explaining mental phenomena. Hume divided the perceptions of the mind into two classes. The members of one class, impressions, he held to have a greater degree of force and vivacity than the members of the other class, ideas. He also supposed that ideas are causally dependent copies of impressions. (...) And, unlike Locke and others, Hume makes positive use of the principle of association, both of the association of ideas, and, in a more limited way, of the association of impressions. Such associations are central to his explanations of causal reasoning, belief, the indirect passions (pride and humility, love and hatred), and sympathy. These views about impressions and ideas and the principles of association form the core of Hume’s science of human nature. Relying on them, he attempts a rigorously empirical investigation of human nature. The resulting system is a remarkable but complex achievement. (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)

John Locke accepts that every perception gives me immediate and intuitive knowledge of my own existence. However, this knowledge is limited to the present moment when I have the perception. If I want to understand the necessary and sufficient conditions of my continued existence over time, Locke argues that it is important to clarify what ‘I’ refers to. While we often do not distinguish the concept of a person from that of a human being in ordinary language, Locke emphasizes that (...) this distinction is important if we want to engage with questions of identity over time. According to Locke, persons are thinking intelligent beings who can consider themselves as extended into the past and future and who are concerned for their happiness and accountable for their actions. Moreover, for Locke a self is a person, considered from a first-personal point of view. I show that the concept of self that he develops in the context of his discussion of persons and personal identity is richer and more complex than the I-concept that he invokes in his version of the cogito. I further argue that Locke’s moral and religious views explain why he emphasizes the need for a conceptual distinction between persons and human beings. In the final section I turn to the reception of Locke’s view by some of his early critics and defenders, including Elizabeth Berkeley Burnet, an anonymous author, and Catharine Trotter Cockburn.

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.

Collection of papers presented at the 2nd and 3rd Budapest Seminar in Early Modern Philosophy.

In this paper I examine the concept of cross-temporal personal identity (diachronicity). This particular form of identity has vexed theorists for centuries -- e.g.,how can a person maintain a belief in the sameness of self over time in the face of continual psychological and physical change? I first discuss various forms of the sameness relation and the criteria that justify their application. I then examine philosophical and psychological treatments of personal diachronicity(for example,Locke's psychological connectedness theory; the role of (...) episodic memory) and find each lacking on logical grounds, empirical grounds, or both. I conclude that to achieve a successful resolution of the issue of the self as a temporal continuant we need to draw a sharp distinction between the feeling of the sameness of one's self and the evidence marshaled in support of that feeling.

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.

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)

Recent research has begun treating the perennial philosophical question, “what makes a person the same over time?” as an empirical question. A long tradition in philosophy holds that psychological continuity and connectedness of memories are at the heart of personal identity. More recent experimental work, following Strohminger & Nichols (2014), has suggested that persistence of moral character, more than memories, is perceived as essential for personal identity. While there is a growing body of evidence supporting these findings, a (...) critique by Starmans & Bloom (2018) suggests that this research program conflates personal identity with mere similarity. To address this criticism, we explore how loss of someone’s morality or memories influence perceptions of identity change, and perceptions of moral duties towards the target of the change. We present participants with a classic ‘body switch’ thought experiment and after assessing perceptions of identity persistence, we present a moral dilemma, asking participants to imagine that one of the patients must die (Study 1) or be left alone in a care home for the rest of their life (Study 2). Our results highlight the importance of the continuity of moral character, suggesting lay intuitions are tracking (something like) personal identity, not just mere similarity. (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)

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 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)

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)

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.

Decision theory explains weakness of will as the result of a conflict of incentives between different transient agents. In this framework, self-control can only be achieved by the I-now altering the incentives or choice-sets of future selves. There is no role for an extended agency over time. However, it is possible to extend game theory to allow multiple levels of agency. At the inter-personal level, theories of team reasoning allow teams to be agents, as well as individuals. I apply (...) team reasoning at the intra-personal level, taking the self as a team of transient agents over time. This allows agents to ask, not just “what should I-now do?’, but also ‘What should I, the person over time do?’, which may enable agents to achieve self-control. The resulting account is Aristotelian in flavour, as it involves reasoning schemata and perception, and it is compatible with some of the psychological findings about self-control. (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.

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.

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.

Two problems seem to plague Adam Smith’s account of sympathy and approbation in The Theory of Moral Sentiments (TMS). First, Smith’s account of sympathy at the beginning of TMS appears to be inconsistent with the account of sympathy at the end of TMS. In particular, it seems that Smith did not appreciate the distinction between ‘self-oriented sympathy’ and ‘other-oriented sympathy’, that is, between imagining being oneself in the actor’s situation and imagining being the actor in the actor’s situation. Second, Smith’s (...) account of approbation, according to which a sentiment of approval arises when there is recognition of concordance between the spectator’s sympathetic passion and the actor’s original passion, seems to face the following problem: since the spectator attains both his own sympathetic passion and the actor’s original passion by sympathizing with the actor, the sympathetic passion of the spectator and the original passion of the actor will necessarily be identical. Therefore, Smith’s account of approbation requires that the spectator utilize both self-oriented and other-oriented sympathy (‘the double-sympathy model of approbation’). I offer a novel developmental account of sympathy in TMS that renders Smith’s account of sympathy consistent and allows for the utilization of the double-sympathy model of approbation. (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)

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

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)

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.

The pronoun ‘I’ refers to myself from the first-person perspective and a person (me) from the third person perspective. Essentially there is something common between the two perspectives taken: ‘I’ from the first person perspective refers to ‘self’; from the third person perspective refers to a ‘person’. Now ‘self’ and ‘person’ signify the same concept. ‘Self’ is a term used in context of first-person statements and ‘person’ is a term used in third person contexts. Both the terms refer to the (...) same concept but from different perspectives. Consequently the terms ‘no-person’ and ‘no-self’ will be taken as synonymous in this article. The use of ‘I’ signifies one more thing – that there exists a ‘self’ or ‘person’ that exists through time, in other words, it signifies ‘self-identity’ or ‘personal identity’. The aim of this article is to analyze the notion of ‘self’ or ‘person’ as denoted in the usage of the pronoun ‘I’. This article would examine ‘I’ as a fictitious entity in the background of the two historical theories of personal identity – David Hume’s theory and the Buddhist theory. (shrink)

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

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)
