I am now typing on a computer I bought two years ago. The computer I bought is identical to the computer on which I type. My computer persists over time. Let us divide our subject matter in two. There is first the question of criteria of identity, the conditions governing when an object of a certain kind, a computer for instance, persists until some later time. There are secondly very general questions about the nature of persistence itself. Here I include (...) the question of temporal parts, as well as certain familiar paradoxes (e.g., the statue and the lump). Following John Perry (1975, Introduction), let us characterize a criterion of identity over time for F s as a way of filling in φ in the following schema: Stages S1 and S2 belong to some continuing F iff φ Defenders of temporal parts (see below) regard S1 and S2 as being temporal parts of the continuing F ; others regard S1 and S2 as different stages in the life history of the continuing F . Thus each camp can make use of Perry’s formula. It is traditional to divide such criteria into those governing persons and those governing anything else. It is further traditional to say that the criterion of identity over time for non-persons involves spatiotemporal continuity. An excellent discussion is Eli Hirsch’s The Concept of Identity1, which utilizes the notion of continuity under a sortal. Kind-terms, or sortals, are terms that specify what kind of or sort of thing an object is. Examples include ‘tree’, ‘car’, and ‘mountain’. Where F is a sortal, Hirsch’s analysis is roughly that stages belong to the same F iff they are connected by a spatiotemporally and qualitatively continuous sequence of F -stages. Unmodified, this analysis prohibits temporally discontinuous entities, such as a watch that is taken apart and then reassembled. Hirsch discusses the necessary modifications. Spatiotemporal continuity analyses face a problem when applied to the persistence of matter. The literature here has been dominated by discussion of examples provided by David Armstrong (1980) and Saul Kripke (unpublished.... (shrink)

Many philosophers have taken there to be an important relation between personal identity and several of our practical concerns (among them moral responsibility, compensation, and self-concern). I articulate four natural methodological assumptions made by those wanting to construct a theory of the relation between identity and practical concerns, and I point out powerful objections to each assumption, objections constituting serious methodological obstacles to the overall project. I then attempt to offer replies to each general objection in a way that leaves (...) the project intact, albeit significantly changed. Perhaps the most important change stems from the recognition that the practical concerns motivating investigation into personal identity turn out to be not univocal, as is typically thought, such that each of the different practical concerns may actually be related to personal identity in very different ways.

Harry Frankfurt introduces the concept of externality. Externality is supposed to be a fact about the structure of an agent's will. We argue that the pre-theorethical basis of externality has a lot more to do with feelings of alienation than it does with the will. Once we realize that intuitions about externality are guided by intuitions about feelings of alienation surprising conclusions follow regarding the structure of our will.

In Epicurean cosmology, material reconstitution, or palingenesis (παλιγγενεσία) is the necessary consequence of the infinity of time and the eternity of atoms. I examine Lucretius’ treatment of this phenomenon (DRN 3.843–864) and consider the extent to which his view enables us to develop an Epicurean response to the question: what makes a person at two different times one and the same person? I offer a reading of this passage in the light of modern accounts of persistence and identity, and what (...) Lucretius states in Books 3 and 4 about memory and the soul’s motions. Guided by the metaphysical implications of this analysis, I determine the type of relation which, according to Lucretius, holds between the mental and the physical. (shrink)

The Problem of Overlappers is a puzzle about what makes it the case, and how we can know, that we have the parts we intuitively think we have. In this paper, I develop and motivate an overlooked solution to this puzzle. According to what I call the self-making view it is within our power to decide what we refer to with the personal pronoun ‘I’, so the truth of most of our beliefs about our parts is ensured by the very (...) mechanism of self-reference. Other than providing an elegant solution to the Problem of Overlappers, the view can be motivated on independent grounds. It also has wide-ranging consequences for how we should be thinking about persons. Among other things, it can help undermine an influential line of argument against the permissibility of elective amputation. After a detailed discussion and defence of the self-making view, I consider some objections to it. I conclude that none of these objections is persuasive and we should at the very least take seriously the idea that we are to some extent self-made. (shrink)

I present an internal problem for David Lewis’s genuine modal realism. My aim is to show that his analysis of modality is inconsistent with his metaphysics. I consider several ways of modifying the Lewisian analysis of modality, but argue that none are successful. I argue that the problem also affects theories related to genuine modal realism, including the stage theory of persistence and modal fictionalism.

Life, whatsoever it is, is a temporal flux. Everything is doomed to change often apparently beyond our awareness. My body appears totally different now, so does my mind. I have gained new attitudes and new ambitions, and a substantial number of old ones have been discarded. But, I am still the same person in an ongoing manner. Besides, recent neuroscientific and psychological evidence has shown that our conscious perception happens as a series of discrete or bounded instants—it emerges in temporally (...) scattered, gappy, and discrete forms. But, if it is so, how does the brain persevere our self-continuity in this gappy setting? How is it possible that despite moment-to-moment changes in my appearance and mind, I am still feeling that I am that person? How can we tackle with this second by second gap and resurrection in our existence which leads to a foundation of wholeness and continuity of our self? How is continuity of self that results in a feeling that one’s life has purpose and meaning preserved? To answer these questions, the problem has been comprehended from a philosophical, psychological, and neuroscientific perspective. I realize that first and foremost fact lies in the temporal nature of identity. Having equipped with these thoughts, in this article, it is hypothesized that according to two principles self-continuity is maintained. It is supposed that there should be a precise temporal integration mechanism in the CNS with the outside world that provides us this smooth, ungappy flow of the Self. However, we are often taken for granted the importance of self-continuity, but it can be challenged by life transitions such as entering adulthood, retirement, senility, emigration, and societal changes such as immigration, globalization, and in much unfortunate and extreme cases of mental illnesses such as schizophrenia.

John Stuart Mill wrote in the opening chapter of Utilitarianism, ‘A test of right and wrong must be the means, one would think, of ascertaining what is right or wrong,’ thus explaining why he thought the work to follow was practically important. In Chapter 3, ‘On the Ultimate Sanction of the Principle of Utility,’ he answers the question, ‘What are the motives to obey the principle of utility?’ This principle is presented as a morality to be adopted. Yet before the (...) nineteenth century was over Henry Sidgwick was proposing that it may well be best, from a utilitarian view, that the utilitarian doctrine is not too widely adopted. Perhaps it should be an esoteric morality.Moreover, Sidgwick argues, it seems contrary to self interest to adhere to an impartially benevolent morality. Devotion to utilitarian duty seems to require that the agent sacrifice his or her own happiness in a devotion to the relief of others that can only ‘partially mitigate’ their distress. Such a morality seems impossibly demanding. Sidgwick’s argument challenges Mill's claim that there is an adequate sanction for adoption of utilitarian morality. (shrink)

This paper explores a distinctive form of social interaction—interpersonal inquiry—in which two or more people attempt to understand one another by engaging in conversation. Like many modes of inquiry into human beings, interpersonal inquiry partly shapes its own objects. How we conduct it thus affects who we become. I present an ethical ideal of conversation to which, I argue, at least some of our interpersonal inquiry ought to aspire. I then consider how this ideal might influence philosophical conceptions of the (...) self. (shrink)

In this paper, I report on a quasi-case study of U.S. presidential identity based on Donald J. Trump’s presidency, demonstrating that Trump is considered by the American public as an antithesis of presidentiality. I then discuss the insights from this study on several critical issues that face identity studies, an expansive area of investigation which has attracted the attention of students from a diverse range of disciplines. I demonstrate that identity is a set of attributes the formation of which is (...) based on the mission of the group and the expected behaviors of members of that group, that the construction of identity is largely a bottom-up and gradual process, and that identity is both preexisting and emergent.

Søren Kierkegaard's thesis, "The Concept of Irony", contains an interesting critique of pure irony. Kierkegaard's critique turns on two main claims: (a) pure irony is an incoherent and thus, unrealizable stance; (b) the pursuit of pure irony is morally enervating, psychologically destructive, and culminates in bondage to moods. In this essay, first I attempt to clarify Kierkegaard's understanding of pure irony as "infinite absolute negativity." Then I set forth his multilayered critique of pure irony. Finally, I consider briefly a distinctly (...) theological component in Kierkegaard's critique. I argue that this feature of Kierkegaard's account can and should be distinguished from the broadly ethical critique of pure irony that I sketch in the second section, even if these components of Kierkegaard's position are found together as a unified whole in "The Concept of Irony". My overall goal in this essay is to reveal the subtlety and plausibility of Kierkegaard's critique of pure irony. I also attempt to disclose the richness of the Hegelian account of ethical life to which Kierkegaard recurs in his thesis. (shrink)

This article reflects upon the increasingly popular claim that animals are persons. Such a claim can take a metaphysical, a moral, or a legal meaning. Animals may or may not be persons, but I challenge the assumption that it is even fruitful to think about the ways in which animals are “persons.” At best, it is a relatively narrow assimilationist conceptual exercise. At worst, it distracts us from conceptualizing more effective strategies to improve the welfare of animals and impoverishes more (...) promising avenues of philosophical investigation on interspecies relations and on the nature and moral status of both animals and human beings.

Sydney Shoemaker has claimed that functionalism, a theory\nabout mental states, implies a certain theory about the\nidentity over time of persons, the entities that have\nmental states. He also claims that persons can survive a\n"Brain-State-Transfer" procedure. My examination of these\nclaims includes description and analysis of imaginary\ncases, but--notably--not appeals to our "intuitions"\nconcerning them. It turns out that Shoemaker's basic\ninsight is correct. But there is no implication that it is\nnecessary. (edited).

The following thesis starts from the question «why be moral?» and adresses an action-theoretic strategy for answering this question in the positive by reference to the constitutive natur of actions. In these debates, the epistemology of action has turned into a central issue. The thesis adresses these debates and develops a novel account of the epistemology: an account that may well turn out to provide a ground for the aforementioned constitutivist strategies.
