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)

According to David Hume, there is nothing to the mind other than the various fleeting events that it hosts. According to commonsense, this is false. But the commonsense view has never been meaningfully elaborated. This short work states an analysis of personal identity that combines Hume's position with the position, so far as there is one, of commonsense, thereby giving much needed substance to the latter.

In this article, we consider three metaphysical theories of personal identity: the soul theory, the body theory, and the psychological theory. Clinical cases are discussed as they present conceptual problems for each of these theories. For the soul theory, the case of Phineas Gage, and cases of pedophilic behavior due to a brain tumor are discussed. For the body theory, hypothetical cases of cephalosomatic anastomosis and actual cases of dicephalic parapagus and craniopagus parasiticus are discussed. For (...) the psychological theory, cases of delusions and memory impairments are discussed. After a discussion of all these cases, we conclude that it is very difficult to unequivocally favor one of these theories, yet we argue that this discussion must be based not on abstract armchair speculation, but rather, consideration of real clinical cases.

In this paper, I defend the view that the identity of indiscernibles could serve as an adequate basis for a general theory of identity. I then show how a theory of essentialism forces one to modify that general theory. In light of both the original and modified theory, I offer a new resolution of some of the classical and contemporary problems of personal identity.

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

It is widely held that Locke propounded a theory of personal identity in terms of consciousness and memory. By ‘theory’ here is meant a set of necessary and sufficient conditions indicating what personal identity consists in. It is also held that this theory is open to obvious and damaging objections, so much so that it has to be supplemented in terms of bodily continuity, either because memory alone is not sufficient, or because the concept of memory (...) is itself dependent upon considerations of bodily continuity. Alternatively it has been suggested that Locke's theory could be modified by allowing that for the purposes of personal identity ‘remember’ should be regarded as a transitive relation. So if A remembers the experiences of B but not those of C, and B remembers the experiences of C, then A, B and C can be regarded as belonging to the same unit of consciousness. (shrink)

Since his contribution to the field of personal identity in 1738 Hume’s theory has been debated thoroughly. Throughout the years there have been multiple critiques of Hume’s theory, but despite the fact that all of these generally appear unsatisfactory, Hume’s theory of personal identity is far from being a popular one in the field. I believe the blame partly falls on Hume himself. Hume’s appendix to Treaties is most often read as expressing a deep concern regarding (...) his own theory, and this concern, I believe, is to blame for his theory never gaining the respect it deserves. After all, why should we listen to Hume if he himself found his theory lacking? It is, however, a mistake to judge Hume’s theory of personal identity, based on the appendix to Treaties. The appendix is far too ambiguity for any real conclusion and it offers nothing that cannot be found in the original chapter on personal identity from Treaties. (shrink)

David lewis has argued that--Despite the 'fission' cases--One may consistently hold both that what matters in survival is "mental continuity and connectedness" and that what matters in survival is identity. To prove his point, He produces a certain theory of persons. Derek parfit and penelope maddy have objected that the theory lewis produces does not actually have the advantages he claims for it. In this paper, The author questions their objections, And then argues that, Even though lewis's theory has (...) many virtues, No sufficiently knowledgeable person can be justified in accepting it (here and now) as an adequate theory of persons.

The problem of diachronic personal identity is this: what explains why a person P1 at time T1 is numerically identical with a person P2 at a later time T2, even if they are not at those times qualitatively identical? One traditional explanation is the soul theory, according to which persons persist in virtue of their nonphysical souls. I argue here that this view faces a new and arguably insuperable dilemma: either souls, like physical bodies, change over time, in (...) which case the soul theory faces an analogue problem of diachronic soul identity, or souls, unlike physical bodies, do not change over time, in which case the soul theory cannot explain why souls relate to particular bodies over time and so at best only partially explains personal identity. I conclude that the soul theory fares no better than physicalist-friendly accounts of personal identity such as bodily- or psychological-continuity-based views. (shrink)

The major concern of the problem of personal identity gravitates around the question of whether a person’s identity is located in the mind or in the body. Scholars have developed different theories such as survivalist and physicalist criteria among others in response to this question. In this paper, I engage with the theory of sense-phenomenalism as an aspect of the physicalist criterion of personal identity to show how it might legitimize racism and colour-branding. Sense-phenomenalism (...) is a body-only model of personal identity that holds that an individual’s identity is determined by the physical features sensually perceptible by other humans in the society. I argue that sense-phenomenalism by reposing a person’s identity on his/her bodily traits might foster social discrimination, deepen the dichotomy between the self and the other and enhance the fabrication of justifications for the denial of individual’s rights.

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

Locke’s theory of personal identity was philosophically groundbreaking for its attempt to establish a non-substantial identity condition. Locke states, “For the same consciousness being preserv’d, whether in the same or different Substances, the personal Identity is preserv’d” (II.xxvii.13). Many have interpreted Locke to think that consciousness identifies a self both synchronically and diachronically by attributing thoughts and actions to a self. Thus, many have attributed to Locke either a memory theory or an appropriation theory of (...) personal identity. But the former stumble on circularity and the latter is insufficient for Locke’s moral theory insofar as he is committed to a theory of divine rectification. The common problem is that Locke’s theory seems to demand an objective, or metaphysical, fact of a continuing consciousness that does not appeal to a traditional notion of substance for the continuity. I’m suggesting something new. In II.xxvii of the Essay, we see an ambiguity in Locke’s use of the term ‘consciousness’. Locke seems to see consciousness as both a mental state by means of which we are aware of ourselves as perceiving and as the ongoing self we are aware of in these conscious states. First, I make the textual argument why we should read Locke as having a conception of a metaphysical fact of a continuing consciousness that does not appeal to thinking or bodily substance to establish its continuity. I then argue that the metaphysical fact of an enduring consciousness is revealed to us as a phenomenological fact of experience. Due to the nature of certain kinds of perceptual situations we have an experience of ourselves as temporally extended. Although the text bears out that Locke seemed to think there is a fact of an ongoing consciousness, I argue that it is consistent with his reluctance elsewhere that he makes no further epistemological or ontological claims about it. Finally, I provide an account of Locke’s understanding of memory and its relation to consciousness that supports the claim that consciousness is something ontologically distinct from either thinking or bodily substance.

In Reasons and Persons Parfit vacillates between two views of personal identity. Both views have unpalatable consequences. According to one view, the question, "Is person A the same as person C?" is always empty. According to the other view, this question is empty only some of the time. The first view is elegant, but it has consequences which are counterintuitive and incompatible with Parfit's later claims. The second view is commonsensical, but its only coherent version is vulnerable to (...) an argument made by Parfit, himself. (shrink)

Il est une opinion fort répandue que la théorie leibnizienne de l'identité personnele dans les Nouveaux Essais est contradictoire car elle renferme deux thèses incompatibles, à savoir, que 1) comme persone, je suis mon esprit, et que 2) je pourrais continuer, sans mon esprit. Dans cette étude, par une interprétation nouvelle de la pensée leibnizienne sur l'identité personnelle dans les Nouveaux Essais, je soutiens que pour Leibniz est vrai mais est faux, et que par conséquence sa théorie est consistante.

Locke’s consciousness-based theory of personal identity resulted not only from his agnosticism on substance, but also from his biblical theology. This theory was intended to complement and sustain Locke’s moral and theological commitments to a system of otherworldly rewards and sanctions as revealed in Scripture. Moreover, he inferred mortalist ideas from the Bible, rejecting the resurrection of the same body and maintaining that the soul dies at physical death and will be resurrected by divine miracle. Accordingly, personal (...) identity is neither in the soul, nor in the body, nor in a union of soul and body. To Locke, personal identity is in consciousness, which, extending “backwards to any past Action or Thought,” enables the self, both in this life and upon resurrection for the Last Judgment, to recognize that “it is the same self now it was then; and ‘tis by the same self with this present one that now reflects on it, that that Action was done” (Essay II.xxvii.9).

Much specific support for theories of personal identity comes from data which is really about 'what matters' in identity. I argue that if we accept Parfit's arguments that identity is not sufficient for what matters, then we should think our subject matter is actually underdetermined and indefinite, and there can be no correct answer to the question 'Under what conditions is P2 identical to P!?'.

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.

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

The main contribution of this work is to develop the account of material constitution presented in Spatially Coinciding Objects (Ratio 24, 1982) and a series of related articles. This account was merely ‘analytical’ in that it applied generously to ‘putative’ examples of distinct entities (individuals, pluralities and masses of stuff) in the same place at the same time. The account herein is ‘critical’ in that it seeks justification for recognizing the existence of entities constituted in addition to the entities that (...) allegedly constitute them. While the earlier account used examples such as a clay statue and the clay of the statue for purposes of illustrating material constitution, the present account would consider ‘reducing’ the statue to the clay, and seeks justification for how to resist this and admit the existence of generable and perishable natural objects in general. The justification sought is ‘deep’ in the sense that (unlike the popular ‘method of cases) it does not belong to ‘descriptive’ metaphysics (in Strawson’s sense) but is sufficiently potent to counter ‘revisionist’ views. Transcendental arguments, beginning with austere assumptions of justification itself, are thereby employed. Suggestions are made about what to conclude about our own identity, which amount to supporting animalism. (shrink)

A prominent view on personal identity over time, Jeff McMahan’s ‘Embodied Mind Account’ (2002) holds that we cease to exist only once our brains can no longer sustain the basic capacity to uphold consciousness. One of the many implications of this view on identity persistence is that we continue to exist throughout even the most severe cases of dementia, until our consciousness irreversibly shuts down. In this paper, I argue that, while the most convincing of prominent accounts (...) of personal identity over time, McMahan’s account faces serious challenges in explanatory power of dementias and related neurodegenerative conditions. Particularly, this becomes visible in the face of emerging methods for neural tissue regeneration, and the possibility of ‘re-emerging patients’. I argue that medical professionals’ neglecting qualitative aspects of identity risks resulting in grave misunderstandings in decision-making processes, and ethically objectionable outcomes in future practices. Finally, I propose revisions which could potentially salvage the great benefits that Embodied Mind Theory still can bring to the field of dementia care in terms of understanding life, death, and identity across the lifespan.

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)

Studying personal identity, the continuity and sameness of persons across lifetimes, is notoriously difficult and competing conceptualizations exist within philosophy and psychology. Personal reidentification, linking persons between points in time is a fundamental step in allocating merit and blame and assigning rights and privileges. Based on Nozick’s closest continuer theory we develop a theoretical framework that explicitly invites a meaningful empirical approach and offers a constructive, integrative solution to current disputes about appropriate experiments. Following Nozick, reidentification involves (...) judging continuers on a metric of continuity and choosing the continuer with the highest acceptable value on this metric. We explore both the metric and its implications for personal identity. Since James, academic theories have variously attributed personal identity to the continuity of memories, psychology, bodies, social networks, and possessions. In our experiments, we measure how participants weighted the relative contributions of these five dimensions in hypothetical fission accidents, in which a person was split into two continuers. Participants allocated compensation money or adjudicated inheritance claims and reidentified the original person. Most decided based on the continuity of memory, personality, and psychology, with some consideration given to the body and social relations. Importantly, many participants identified the original with both continuers simultaneously, violating the transitivity of identity relations. We discuss the findings and their relevance for philosophy and psychology and place our approach within the current theoretical and empirical landscape. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:REID' S CRITICISM OF HUME'S THEORY OF PERSONAL IDENTITY One of the most interesting philosophical controversies is that between Reid and Hume, considered as representatives of two different sorts of empiricism. Hume, for these purposes, represents 'radical' empiricism, and the attempt to base knowledge solely on experience and what can be validly inferred from it, regardless of how far this leads one from everyday notions and beliefs. (...) Reid, in contrast, represents 'common sense' empiricism, and the view that the. results of experience and deduction must conform to a number of 'first principles or intuitive judgments' (Essays on the intellectual powers of man, VI, 4), which aie unprovable, but which no one can avoid accepting. It is important to be clear about the status of Reid' s 'intuitive judgments', or 'principles of common sense'. They are not merely the general beliefs of a particular culture, which could be 'vulgar errors or preJUdICeS''. Nor are they merely beliefs generally held by people uncorrupted by philosophy. They are assumptions which have to be made if theoretical or practical activity is to be possible at all, principles which are always accepted in practice even by those who deny them in theory. For example, although the uniformity of nature is not a logically necessary truth, everybody always thinks and acts in ways that presuppose that it is true: 'Nature is governed by fixed laws, and if it were not so, there could be no such thing as prudence in human conduct.... the whole fabric of natural philosophy is built upon this principle.' (Essays, VI, 5) Again, everyone, even a theoretical determinist, makes moral judgments and deliberates what to do; and these activities presuppose a belief in human free will. (Essays, ibid.) Hume himself, as Reid was aware, accepted the validity of some principles of this sort, notably of the 42. uniformity of nature. But Reid was dissatisfied with Hume's account, partly because he thought Hume had rejected far too much, and partly because of the grounds Hume gives for accepting, for example, the validity of induction, and the existence of the external physical world. Hume regards these beliefs as non-rational, and deriving from our psychological make-up; it is nature and not reason which causes the belief in an ordered physical reality. In Hume's eyes this is a sufficient justification: if our nature compels us to believe something, this is as good a ground for believing it as any other. Reid, on the other hand, believed, first, that there were many more principles of this sort than Hume had acknowledged, and secondly, that the justification of them was rational, and not merely psychologically determined, since it was based on the impossibility of thinking and acting coherently without them. Hence, even though Hume builds up with one hand what he pulls 'down with the other, and destroys the rational basis for belief only to replace it by one based on human nature and psychology, Reid continues to treat him as the archsceptic. In constructing his list of first principles in Essays, VI, 5, Reid explicitly or implicitly attacks Hume's 'scepticism' on five points - the existence of the mind; the existence of the physical world and the reliability of our senses; the reliability of memory; the reliability of reason; and the uniformity of nature. Against this scepticism he deploys three types of argument. The first is the argument from the universal beliefs of mankind, particular!/ as displayed in the structural features supposedly common to all languages. The second is the argument that the position of the sceptic is, when its consequences are worked out, either self-contradictory or incoherent. And the third is the argument already mentioned, that this position is inconsistent with other beliefs which the sceptic inevitably holds, since he thinks and acts in ways which are 43. inconsistent with their falsity, and cannot avoid doing so. To assess the force of Reid' s attacks, we have to consider both the strength of arguments of this sort in general and whether they apply in all these five cases. In this article, I want to concentrate on the first issue of the five, that of personal identity. Apart from displaying Reid... (shrink)

This paper assesses the first-person authority account (FPA) of gender, according to which X's self-identification of what X's gender is, is the final say on what X's gender is, such that if others disagree, they are mistaken. One main reason in support of FPA is respecting X's autonomy—that is, overriding X's self-identification amounts to denying X's autonomy. Ozturk criticizes this view using analogies of religious and patriotic self-identifications, such that there are cases in which someone can permissibly claim that another (...) is not, say, a true Muslim or a true patriot. This implies that there might also be cases of permissible rejections of gender self-identification. Ozturk offers instead the negotiative theory of identity, according to which it is permissible to reject a self identification as long as three constraints are satisfied: no harm is done to the self-identifier, and their privacy and dignity are not violated. (This essay is a slightly revised version of that found in the 7th edition of The Philosophy of Sex.). (shrink)

A philosophical account of personal identity - in terms of the maintenance of fundamental beliefs, principles and commitments by spatiotemporally continuous particulars - is sketched, an account which is able to incorporate a social and relational conception of personal identity, and thus serve as the basis for a social psychological theory of personal identity - in terms of the pursuit of identity projects’within social collectives. Some implications of this theory are developed, concerning the (...) relation between identity and individualism, responsibility and social labeling. The theory develops an account of the social constitution of personal identity that is consistent with a realist conception of social psychological theories of identity: as objective theoretical descriptions of the social dimensions of identity.

The article sets out aspects of locke's theory of personal identity which were seen by contemporaries to be not only fallacious but also to conflict with christian doctrine regarding the soul. A modified theory is then educed, From berkeley, Butler, William law and other divines, Which avoids these fallacies, Is epistemologically more rigorous and arguably expressed christian doctrine more accurately. This is seen as a forerunner of some central concerns of romantic theology.

The main target of The Kinds of Things is the Lockean-Humean view of personal identity that had its most controversial expression in Parfit and that so thoroughly shaped the debate on the issue. Doepke develops an alternative Kantian-Aristotelian account of personal identity, partly by analyzng the demerits of the Lockean-Humean view. While locating itself in the landscape of the traditional debate, though, the book is very atypical of it.

The first-person authority view (FPA) is the current dominant view about what someone’s gender is. According to FPA the person has authority over her own gender identity; her sincere self-identification trumps the opinions of others. There are two versions of FPA: epistemic and ethical. Both versions try to explain why a person has authority over her own gender identity. But both have problems. Epistemic FPA attributes to the self-identifier an unrealistic degree of doxastic reliability. Ethical FPA implies the (...) existence of an unreasonably strong and unqualified obligation on the part of others not to reject the person’s identification. This essay offers an alternative: the negotiative theory of identity. Unlike epistemic FPA, the negotiative theory doesn’t presume the reliability of self-directed beliefs. Unlike ethical FPA, the negotiative theory doesn’t imply an obligation not to reject. Instead, it contends that an act of rejection is morally permissible if and only if it respects three ethical and epistemic constraints. In doing so, the negotiative theory combines the strengths and avoids the weaknesses of both versions of FPA, and gives us substantive insight into how far first-person authority reaches in terms of grounding rights and obligating others.

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.

This book examines the conception of the person at work in John Rawls's writings from Theory of Justice to Justice as Fairness: A Restatement. The book aims to show that objections to Rawls's political conception of the person fail and that a Rawlsian conception of political identity is defensible. The book shows that the debate between liberals and communitarians is relevant to the current debate regarding perfectionism and neutrality in politics, and clarifies the debate between Rawls and communitarians in (...) a way that will promote fruitful discussion on the issue of political identity. It does this by providing a clearer account of a conception of personal identity according to which persons are socially constituted, including the intuitions and assumptions underlying the communitarians' conception of persons as "socially constituted." It examines the communitarian objections to liberal political theory and to the liberal conception of persons, the "unencumbered self." The book differentiates between two types of objection to the liberal conception of persons: the metaphysical and normative. It explains Rawls's political conception of persons, and the metaphysical and normative commitments Rawls incurs-and does not incur-in virtue of that conception. It shows that both kind of objection to Rawls's political conception of the person fail. Finally, modifying Rawls's political conception of the person, a Rawlsian conception of political identity is explained and defended. (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)

Theories of personal identity try to explain what the identity of a person necessarily consists in, but frequently leave open what kind of necessity is at issue. This paper is concerned with conceptual necessity. It proposes an analysis of the concept of personal identity in terms of a definite description. The analysis coheres with out judgments about clear cases and explains why cases of division seem indeterminate. The apparent indeterminacy results from attempting to apply (...) a definite description to a situation in which more than one object would satisfy the description. The definite description analysis also explains the strengths of the influential no-branching theory, while avoiding the problems with that view. The no-branching theory is in effect a second-order analysis, i.e., a combination of the definite description analysis of personal identity plus a Russellian analysis of the definite description.
