Visible Identities critiques the critiques of identity and of identity politics and argues that identities are real but not necessarily a political problem. Moreover, the book explores the material infrastructure of gendered identity, the experimental aspects of racial subjectivity for both whites and non-whites, and in several chapters looks specifically at Latio identity.

Identities formed with proper names may be contingent. this claim is made first through an example. the paper then develops a theory of the semantics of concrete things, with contingent identity as a consequence. this general theory lets concrete things be made up canonically from fundamental physical entities. it includes theories of proper names, variables, cross-world identity with respect to a sortal, and modal and dispositional properties. the theory, it is argued, is coherent and superior to its rivals, (...) in that it stems naturally from a systematic picture of the physical world.

When philosophers address personal identity, they usually explore numerical identity: what are the criteria for a person's continuing existence? When non-philosophers address personal identity, they often have in mind narrative identity: Which characteristics of a particular person are salient to her self-conception? This book develops accounts of both senses of identity, arguing that both are normatively important, and is unique in its exploration of a range of issues in bioethics through the lens of identity. (...) Defending a biological view of our numerical identity and a framework for understanding narrative identity, DeGrazia investigates various issues for which considerations of identity prove critical: the definition of death; the authority of advance directives in cases of severe dementia; the use of enhancement technologies; prenatal genetic interventions; and certain types of reproductive choices. He demonstrates the power of personal identity theory to illuminate issues in bioethics as they bring philosophical theory to life. (shrink)

_Identity and Discrimination_, originally published in 1990 and the first book by respected philosopher Timothy Williamson, is now reissued and updated with the inclusion of significant new material.

Identity-Relative Paternalism, as defended by Wilkinson, holds that paternalistic intervention is justified to prevent an individual from doing to their future selves (where there are weakened prudential unity relations between the current and future self) what it would be justified to prevent them from doing to others.1 Wilkinson, drawing on the work of Parfit and others, defends the notion of Identity-Relative Paternalism from a series of objections. I argue here, however, that Wilkinson overlooks a significant problem for (...) class='Hi'>Identity-Relative Paternalism—namely, that it yields unactionable and self-contradictory results when applied to choices where both options present potential harms to future selves. To illustrate this point, let us consider the following: > A is an acclaimed oboist, for whom the practice and performance of music has brought deep joy throughout their adult life. A, however, develops a condition which will not only cause the rapid loss of their manual dexterity and capacity to hear, but will also certainly be fatal within the year. Suppose further that Drug Z, if taken now, will slow the loss of A ’s dexterity and hearing, but will hasten their demise by a number of months. > > A considers the choice of whether or not to take the drug. A believes that they have had a long and joyful life, but would, all else equal, like to spend as much time as possible with their family. However, A also understands that, without the capacity to enjoy the music which has been central to their life, that those remaining months would likely be joyless in a meaningful way. Taking this background, let us consider the first of A ’s options: to prioritise retaining their ability to enjoy music, and, therefore, to take the drug. Within this branch of the choice, there are two potential future selves: call these …. (shrink)

Identity and Difference consists of English translations and the original German versions of two little-known lectures given in 1957 by Martin Heidegger, "The Principle of Identity" and "The Onto-theo-logical Constitution of Metaphysics.

Steven French and Decio Krause examine the metaphysical foundations of quantum physics. They draw together historical, logical, and philosophical perspectives on the fundamental nature of quantum particles and offer new insights on a range of important issues. Focusing on the concepts of identity and individuality, the authors explore two alternative metaphysical views; according to one, quantum particles are no different from books, tables, and people in this respect; according to the other, they most certainly are. Each view comes with (...) certain costs attached and after describing their origins in the history of quantum theory, the authors carefully consider whether these costs are worth bearing. Recent contributions to these discussions are analyzed in detail and the authors present their own original perspective on the issues. The final chapter suggests how this perspective can be taken forward in the context of quantum field theory. (shrink)

Personal identity deals with questions about ourselves qua people (or persons). Many of these questions are familiar ones that occur to everyone at some time: What am I? When did I begin? What will happen to me when I die? Discussions of personal identity go right back to the origins of Western philosophy, and most major figures have had something to say about it. (There is also a rich literature on personal identity in Eastern philosophy, which I (...) am not competent to discuss. Collins 1982 is a good source.). (shrink)

I propose formulating identity criteria as generic statements of ground, thereby avoiding objections that have been made to the more usual formulations.

Are identity criteria grounding principles? A prima facie answer to this question is positive. Specifically, two-level identity criteria can be taken as principles related to issues of identity among objects of a given kind compared with objects of a more basic kind. Moreover, they are grounding metaphysical principles of some objects with regard to others. In the first part of the paper we criticise this prima facie natural reading of identity criteria. This result does not mean (...) that identity criteria could not be taken as grounding principles. In the second part, we propose some basic steps towards a conceptual reading of grounding. Such a way of understanding it goes along with an epistemic reading of identity criteria. (shrink)

What does it mean to say that this person at this time is 'the same' as that person at an earlier time? If the brain is damaged or the memory lost, how far does a person's identity continue? In this book two eminent philosophers develop very different approaches to the problem.

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

The topic of personal identity has prompted some of the liveliest and most interesting debates in recent philosophy. In a fascinating new contribution to the discussion, Peter Unger presents a psychologically aimed, but physically based, account of our identity over time. While supporting the account, he explains why many influential contemporary philosophers have underrated the importance of physical continuity to our survival, casting a new light on the work of Lewis, Nagel, Nozick, Parfit, Perry, Shoemaker, and others. Deriving (...) from his discussion of our identity itself, Unger produces a novel but commonsensical theory of the relations between identity and some of our deepest concerns. In a conservative but flexible spirit, he explores the implications of his theory for questions of value and of the good life. (shrink)

ABSTRACT: This essay examines and criticizes a set of Kantian objections to Parfit's attempt in Reasons and Persons to connect his theory of personal identity to practical rationality and moral philosophy. Several of Parfit's critics have tried to sever the link he forges between his metaphysical and practical conclusions by invoking the Kantian thought that even if we accept his metaphysical theory of personal identity, we still have good practical grounds for rejecting that theory when deliberating about what (...) to do. The argument between Parfit and his opponents illuminates broader questions about the relationship between our metaphysical beliefs and ourpractical reasons.RÉSUMÉ: Cet article examine et critique un ensemble d'objections kantiennes à la tentative de Parfit, dans Reasons and Persons, d'ajuster sa théorie de l'identité personnelle à la rationalité pratique et à la philosophie morale. Plusieurs des critiques de Parfit ont essayé de rompre le lien qu'il tisse entre ses conclusions métaphysiques et pratiques en évoquant l'idée kantienne selon -laquelle, même si nous acceptons sa théorie métaphysique de l'identité personnelle, il existe cependant de bonnes raisons pratiques de rejeter cette théorie lorsque nous délibérons à propos de ce que nous devons faire. Le débat entre Parfit et ses adversaires nous éclaire sur un questionnement plus large à propos du rapport entre croyance métaphysique et raison pratique. (shrink)

Suppose that X and Y can’t possibly exist apart in reality; then—by definition—there’s no real distinction between them, only a conceptual distinction. There’s a conceptual distinction between a rectilinear figure’s triangularity and its trilaterality, for example, but no real distinction. In fundamental metaphysics there is no real distinction between an object’s categorical properties and its dispositional properties. So too there is no real distinction between an object and its properties. And in fundamental metaphysics, for X and Y to be such (...) that there is no real distinction between them is for them to be identical. (shrink)

Terence Parsons presents a lively and controversial study of philosophical questions about identity. Because many puzzles about identity remain unsolved, some people believe that they are questions that have no answers and that there is a problem with the language used to formulate them. Parsons explores a different possibility: that such puzzles lack answers because of the way the world is (or because of the way the world is not). He claims that there is genuine indeterminacy of (...) class='Hi'>identity in the world. He articulates such a view in detail and defends it from a host of criticisms. (shrink)

Based on the ongoing work of the agenda-setting Future of Minority Studies national research project, Identity Politics Reconsidered reconceptualizes the scholarly and political significance of social identity. It focuses on the deployment of “identity” within ethnic-, women’s-, disability-, and gay and lesbian studies in order to stimulate discussion about issues that are simultaneously theoretical and practical, ranging from ethics and epistemology to political theory and pedagogical practice. This collection of powerful essays by both well-known and emerging scholars (...) offers original answers to questions concerning the analytical legitimacy of “identity” and “experience,” and the relationships among cultural autonomy, moral universalism, and progressive politics.

ABSTRACT It has become standard to conceive of metalinguistic disagreement as motivated by a form of negotiation, aimed at reaching consensus because of the practical consequences of using a word with one content rather than another. This paper presents an alternative motive for expressing and pursuing metalinguistic disagreement. In using words with given criteria, we betray our location amongst social categories or groups. Because of this, metalinguistic disagreement can be used as a stage upon which to perform a social (...) class='Hi'>identity. The ways in which metalinguistic disagreements motivated in this way diverge in character from metalinguistic negotiations are described, as are several consequences of the existence of metalinguistic disagreements motivated in this way.

Putative counterexamples to the Principle of Identity of Indiscernibles (PII) are notoriously inconclusive. I establish ground rules for debate in this area, offer a new response to such counterexamples for friends of the PII, but then argue that no response is entirely satisfactory. Finally, I undermine some positive arguments for PII.

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)

Traditionally, this puzzle has been solved in various ways. Aristotle, for example, distinguished between “accidental” and “essential” changes. Accidental changes are ones that don't result in a change in an objects' identity after the change, such as when a house is painted, or one's hair turns gray, etc. Aristotle thought of these as changes in the accidental properties of a thing. Essential changes, by contrast, are those which don't preserve the identity of the object when it changes, such (...) as when a house burns to the ground and becomes ashes, or when someone dies. Armed with these distinctions, Aristotle would then say that, in the case of accidental changes, (1) and (2) are both false—a changing thing can really change one of its “accidental properties” and yet literally remain one and the same thing before and after the change.

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)

A theory of gender ought to be compatible with trans-inclusive definitions of gender identity terms, such as ‘woman’ and ‘man’. Appealing to this principle of trans-inclusion, Katharine Jenkins argues that we ought to endorse a dual social position and identity theory of gender. Here, I argue that Jenkins’s dual theory of gender fails to be trans-inclusive for the following reasons: it cannot generate a definition of ‘woman’ that extends to include all trans women, and it understands transgender gender (...) identity through a cisgender frame.

Some authors have claimed that ante rem structuralism has problems with structures that have indiscernible places. In response, I argue that there is no requirement that mathematical objects be individuated in a non-trivial way. Metaphysical principles and intuitions to the contrary do not stand up to ordinary mathematical practice, which presupposes an identity relation that, in a sense, cannot be defined. In complex analysis, the two square roots of –1 are indiscernible: anything true of one of them is true (...) of the other. I suggest that ‘i’ functions like a parameter in natural deduction systems. I gave an early version of this paper at a workshop on structuralism in mathematics and science, held in the Autumn of 2006, at Bristol University.

Identity Economics provides an important and compelling new way to understand human behavior, revealing how our identities--and not just economic incentives--influence our decisions. In 1995, economist Rachel Kranton wrote future Nobel Prize-winner George Akerlof a letter insisting that his most recent paper was wrong. Identity, she argued, was the missing element that would help to explain why people--facing the same economic circumstances--would make different choices. This was the beginning of a fourteen-year collaboration--and of Identity Economics. The authors (...) explain how our conception of who we are and who we want to be may shape our economic lives more than any other factor, affecting how hard we work, and how we learn, spend, and save. Identity economics is a new way to understand people's decisions--at work, at school, and at home. With it, we can better appreciate why incentives like stock options work or don't; why some schools succeed and others don't; why some cities and towns don't invest in their futures--and much, much more. Identity Economics bridges a critical gap in the social sciences. It brings identity and norms to economics. People's notions of what is proper, and what is forbidden, and for whom, are fundamental to how hard they work, and how they learn, spend, and save. Thus people's identity--their conception of who they are, and of who they choose to be--may be the most important factor affecting their economic lives. And the limits placed by society on people's identity can also be crucial determinants of their economic well-being. (shrink)

What is the self? And how does it relate to the body? In the second edition of Personal Identity, Harold Noonan presents the major historical theories of personal identity, particularly those of Locke, Leibniz, Butler, Reid and Hume. Noonan goes on to give a careful analysis of what the problem of personal identity is, and its place in the context of more general puzzles about identity. He then moves on to consider the main issues and arguments (...) which are the subject of current debate, including the work of Bernard Williams and Derek Parfit, and makes new and challenging interpretations of them. This new edition contains additional material assessing the biological approach which has become increasingly popular in recent years, and extends the treatment of indeterminate identity to take account of the epistemic view of vagueness. This book covers the problem of personal identity from its origin in Locke's work to the most recent debates in the philosophical literature, and will be invaluablereading for any student of the topic.

Jonathan Lowe argues that metaphysics should be restored to a central position in philosophy, as the most fundamental form of rational inquiry, whose findings underpin those of all other disciplines. He portrays metaphysics as charting the possibilities of existence, by idetifying the categories of being and the relations of ontological dependency between entities of different categories. He proceeds to set out a unified and original metaphysical system: he defends a substance ontology, according to which the existence of the world s (...) one world in time depends upon the existence of persisting things which retain their identity over time and through processes of qualitative change. And he contends that even necessary beings, such as the abstract objects of mathematics, depend ultimately for their existence upon there being a concrete world of enduring substances. Within his system of metaphysics Lowe seeks to answer many of the deepest and most challenging questions in philosophy. (shrink)

In the last two decades, interest in narrative conceptions of identity has grown exponentially, though there is little agreement about what a "life-narrative" might be. In connecting Kierkegaard with virtue ethics, several scholars have recently argued that narrative models of selves and MacIntyre's concept of the unity of a life help make sense of Kierkegaard's existential stages and, in particular, explain the transition from "aesthetic" to "ethical" modes of life. But others have recently raised difficult questions both for these (...) readings of Kierkegaard and for narrative accounts of identity that draw on the work of MacIntyre in general. While some of these objections concern a strong kind of unity or "wholeheartedness" among an agent's long-term goals or cares, the fundamental objection raised by critics is that personal identity cannot _be_ a narrative, since stories are artifacts made by persons. In this book, Davenport defends the narrative approach to practical identity and autonomy in general, and to Kierkegaard's stages in particular. (shrink)

This volume collects a number of Perry's classic works on personal identity as well as four new pieces, 'The Two Faces of Identity', 'Persons and Information', 'Self-Notions and The Self' and 'The Sense of Identity'. Perry's Introduction puts his own work and that of others on the issues of identity and personal identity in the context of philosophical studies of mind and language over the past thirty years.

According to realist structuralism, mathematical objects are places in abstract structures. We argue that in spite of its many attractions, realist structuralism must be rejected. For, first, mathematical structures typically contain intra-structurally indiscernible places. Second, any account of place-identity available to the realist structuralist entails that intra-structurally indiscernible places are identical. Since for her mathematical singular terms denote places in structures, she would have to say, for example, that 1 = − 1 in the group (Z, +). We call (...) this the identity problem and conclude that nominalism is presently the safest route for the structuralist. (shrink)

Dominic Wilkinson’s defence of identity-relative paternalism raises many important issues that are well worth considering. In this short paper, I will argue that there could be two important differences between the first-party and third-party cases that Wilkinson discusses, namely, a difference in associative duties and how the decision relates to the decision maker’s own autonomous life. This could mean that identity-relative paternalism is impermissible in a greater number of cases than he suggests.

_Personal Identity and Self-Consciousness_ is about persons and personal identity. What are we? And why does personal identity matter? Brian Garrett, using jargon-free language, addresses questions in the metaphysics of personal identity, questions in value theory, and discusses questions about the first person singular. Brian Garrett makes an important contribution to the philosophy of personal identity and mind, and to epistemology.

This paper explores the significant strengths of Fricker's account, and then develops the following questions. Can volitional epistemic practice correct for non-volitional prejudices? How can we address the structural causes of credibility-deflation? Are the motivations behind identity prejudice mostly other-directed or self-directed? And does Fricker aim for neutrality vis-à-vis identity, in which case her account conflicts with standpoint theory?

Identity metaphysics finds identity or unity where other metaphysical theories find difference or diversity. It denies the fundamentality of ontological distinctions that other theories treat as fundamental. It’s opposed to separatism, which mistakes natural conceptual distinctions for ground-floor ontological differences. It proposes that the distinctions between the concepts SUBSTANCE, OBJECT, QUALITY, PROPERTY, PROCESS, STATE, and EVENT are metaphysically superficial; so too the distinctions between the concepts ENERGY, LAWSOFNATURE, FORCE, CAUSATION, POWER, and NATURALNECESSITY. So too the distinction between these (...) two sets of concepts. “Thinking takes apart what is really one” (Nietzsche 1885). (shrink)

How can we think about identities in the wake of feminist critiques of identity and identity politics? Allison Weir rethinks conceptions of individual and collective identities in relation to freedom.

In the heated debates over identity politics, few theorists have looked carefully at the conceptualizations of identity assumed by all sides. Visible Identities fills this gap. Drawing on both philosophical sources as well as theories and empirical studies in the social sciences, Martín Alcoff makes a strong case that identities are not like special interests, nor are they doomed to oppositional politics, nor do they inevitably lead to conformism, essentialism, or reductive approaches to judging others. Identities are historical (...) formations and their political implications are open to interpretation. But identities such as race and gender also have a powerful visual and material aspect that eliminativists and social constructionists often underestimate.Visible Identities offers a careful analysis of the political and philosophical worries about identity and argues that these worries are neither supported by the empirical data nor grounded in realistic understandings of what identities are. Martín Alcoff develops a more realistic characterization of identity in general through combining phenomenological approaches to embodiment with hermeneutic concepts of the interpretive horizon. Besides addressing the general contours of social identity, Martín Alcoff develops an account of the material infrastructure of gendered identity, compares and contrasts gender identities with racialized ones, and explores the experiential aspects of racial subjectivity for both whites and non-whites. In several chapters she looks specifically at Latino identity as well, including its relationship to concepts of race, the specific forms of anti-Latino racism, and the politics of mestizo or hybrid identity.

This book gathers together thirteen of Peter van Inwagen's essays on metaphysics, several of which have acquired the status of modern classics in their field. They range widely across such topics as Quine's philosophy of quantification, the ontology of fiction, the part-whole relation, the theory of 'temporal parts', and human knowledge of modal truths. In addition, van Inwagen considers the question as to whether the psychological continuity theory of personal identity is compatible with materialism, and defends the thesis that (...) possible states of affairs are abstract objects, in opposition to David Lewis's 'extreme modal realism'. A specially-written introduction completes the collection, which will be an invaluable resource for anyone interested in metaphysics. (shrink)

Issues of identity and reduction have monopolized much of the philosopher of mind’s time over the past several decades. Interestingly, while investigations of these topics have proceeded at a steady rate, the motivations for doing so have shifted. When the early identity theorists, e.g. U. T. Place ( 1956 ), Herbert Feigl ( 1958 ), and J. J. C. Smart ( 1959 , 1961 ), fi rst gave voice to the idea that mental events might be identical to (...) brain processes, they had as their intended foil the view that minds are immaterial substances. But very few philosophers of mind today take this proposal seriously. Why, then, the continued interest in identity and reduction? Th e concern, as philosophers like Hilary Putnam and Jerry Fodor have expressed it, is that a victory for identity or reduction is a defeat for psychology. For if minds are physical, or if mental events are physical events, then psychologists might as well disassemble their laboratories, making room for the neuroscientists and molecular biologists who are in a better position to explain those phenomena once misdescribed as “psychological.” Th e worry nowadays is not that locating thought in immaterial souls will make psychology intractable, but that locating thoughts in material brains will make it otiose.

In a recent article, Wilkinson puts forward the notion of identity-relative paternalism. According to Wilkinson’s final formulation of this principle, ‘[i]ndividuals should be prevented from doing to future selves (where there are weakened prudential unity relations between the current and future self) what it would be justified to prevent them from doing to others’.1 In medical ethics, it is usually assumed that hard paternalism, that is, acting against a competent person’s wishes for their own benefit, is not justified. According (...) to Mill’s harm principle, we may only limit people’s freedom if they cause harm to others.2 Harm to self is not a sufficient reason for overriding competent persons’ decisions. Wilkinson, however, draws on Parfit’s reductionist view of personal identity to argue that sometimes, patients’ future selves are sufficiently disconnected from their present selves to treat future selves like different persons. If a competent person’s medical decision negatively affects a future self, this should be treated like a case of harm to others. Thus, overriding competent persons’ decisions in such cases—and treating them against their will—could be justified. In this commentary, I point out two problems with this approach. First, I demonstrate that the cases Wilkinson’s argument is based on are not examples of harm to others but rather cases of surrogate decision making gone wrong, …. (shrink)

Many philosophers hypothesize that our concept of personal identity is partly constituted by the one-person-one-place rule, which states that a person can only be in one place at a time. This hypothesis has been assumed by the most influential contemporary work on personal identity. In this paper, we report a series of studies testing whether the hypothesis is true. In these studies, people consistently judged that the same person existed in two different places at the same time. This (...) result undermines some widely held philosophical assumptions, supports others, and fits well with recent discoveries on identity judgments about inanimate objects and non-human animals.

Background: Recent literature on addiction and judgments about the characteristics of agents has focused on the implications of adopting a ‘brain disease’ versus ‘moral weakness’ model of addiction. Typically, such judgments have to do with what capacities an agent has (e.g., the ability to abstain from substance use). Much less work, however, has been conducted on the relationship between addiction and judgments about an agent’s identity, including whether or to what extent an individual is seen as the same person (...) after becoming addicted. Methods: We conducted a series of vignette-based experiments (total N = 3,620) to assess lay attitudes concerning addiction and identity persistence, systematically manipulating key characteristics of agents and their drug of addiction. Conclusions: In Study 1, we found that US participants judged an agent who became addicted to drugs as being closer to ‘a completely different person’ than ‘completely the same person’ as the agent who existed prior to the addiction. In Studies 2-6, we investigated the intuitive basis for this result, finding that lay judgments of altered identity as a consequence of drug use and addiction are driven primarily by perceived negative changes in the moral character of drug users, who are seen as having deviated from their good true selves.
