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)

This paper is a rejoinder to a critique by richard hull in a previous issue. hull denied the legitimacy of moving from the thesis that there are certain one-to-one correlations between mental and physical properties to the thesis that the mental and physical are one and the same. i argue that the move can be justified if it is taken not as deductive but as inductive. given the right sort of correlations, it may be fruitful to conceive of the mental (...) as identical with the physical.

Identity criteria are used to confer ontological respectability: Only entities with clearly determined identity criteria are ontologically acceptable. From a logical point of view, identity criteria should mirror the identity relation in being reflexive, symmetrical, and transitive. However, this logical constraint is only rarely met. More precisely, in some cases, the relation representing the identity condition fails to be transitive. We consider the proposals given so far to give logical adequacy to inadequate (...) identity conditions. We focus on the most refined proposal and expand its formal framework by taking into account two further aspects that we consider essential in the application of identity criteria to obtain logical adequacy: contexts and granular levels. (shrink)

In this paper we introduce some logical and philosophical refinements to OntoClean, first by developing some formal constraints on identity criteria, secondly by specifying a kind of identity criteria, two level identity criteria, whose role is to explain an identity among some entities referring to some other, more basic, entities. Using such refinement we add a formal constraint to the stock of OntoClean meta-constraints (OC+). We, then, observe that two level identity (...) class='Hi'>criteria have an intuitive reading in terms of dependence of a kind of entities on some other entities, possibly specified in terms of a grounding relation. Are identity criteria grounding principles? In the second part of the paper we discuss this option. (shrink)

I explore proposals for stating identity criteria in terms of ground. I also address considerations for and against taking identity and distinctness facts to be ungrounded.

In this paper, a general perspective on criteria of identity of kinds of objects is developed. The question of the admissibility of impredicative or circular identity criteria is investigated in the light of the view that is articulated. It is argued that in and of itself impredicativity does not constitute sufficient grounds for rejecting a putative identity criterion. The view that is presented is applied to Davidson’s criterion of identity for events and to the (...) structuralist criterion of identity of places in a structure. (shrink)

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

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 (...) 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.

Identity criteria are powerful tools for the metaphysician. They tell us when items are identical or distinct. Some varieties of identity criteria also try to explain in virtue of what items are identical or distinct. This Element has two objectives: to discuss formulations of identity criteria and to take a closer look at one notorious criterion of object identity, Leibniz's Law. The first section concerns the form of identity criteria. The second (...) section concerns the better-regarded half of Leibniz's Law, the indiscernibility of identicals. The third section turns to the more controversial half of Leibniz's Law, the identity of indiscernibles. The author considers alternatives to Leibniz's Law as well as the possibility that there are no adequate identity criteria to be found. (shrink)

Anthony Everett () argues that those who embrace the reality of fictional entities run into trouble when it comes to specifying criteria of character identity. More specifically, he argues that realists must reject natural principles governing the identity and distinctness of fictional characters due to the existence of fictions which leave it indeterminate whether certain characters are identical and the existence of fictions which say inconsistent things about the identities of their characters. Everett's critique has deservedly drawn (...) much attention and a number of defensive moves have been made by, or on the behalf of, fictional realists. My goal in this paper is to move this debate on a further step. I have three goals: to clarify the importance of Everett's discussion of identity criteria within the context of fictional realism, to reassess Everett's objections to realism in light of the resultant literature, and to develop a novel strategy for responding to Everett's concerns. On the approach to be developed, the problems emerge due to an indeterminacy inherent in the concept of a fictional character itself. (shrink)

This paper points out a tension between Agustín Rayo's criteria for singulartermhood and his explicit views on the status of Hybrid Identities, that is, identity statements that use singular terms from two different Systems of Representation, such as "7=Julius Caesar" or more suggestively "I am b" where "b" is a singular term referring to my brain. It argues that non-trivial Hybrid Identities are common and important in philosophy and elsewhere, and it suggests a friendly alternative that involves treating (...) Hybrid Identities on the model of Rayo's "Just Is" statements. The last section of the paper points out that even this friendly alternative has counterintuitive consequences when combined with the metaphysical conventionalism that Rayo finds attractive, when it comes to questions of personal identity over time.

The project takes as its starting point our conflicting intuitions about personal identity exposed by Bernard Williams' thought experiment involving the switching of bodies in "The Self and the Future." The conflicted intuitions are identified as animalist and psychologist and correspond roughly with the two major approaches to personal identity. The traditional strategy to resolve the conflict---thought experiments---is critically examined and the project concludes that proper thought experiments will reveal the conflict but are unlikely to resolve it. A (...) new reading of the conflict is proposed. The concept of the person is a cluster concept with distinct components: biological human beings, rational agency and psychological continuity, where the latter is construed as the temporal analog of phenomenological unity at a time. The project then suggests that moral theory is best pursued not by a naturalist conception of persons that unites the components of the cluster, but by a novel conception that separates them. This can be accomplished best by eliminating the concept of the person altogether. Objections that the concept of the person is ineliminable are considered and rejected, as are objections that the nature of conflict is not reason enough to abandon the concept. Personhood's centrality for value theory is questioned and the eliminativist strategy is defended on the grounds that responsibility, self-concern and moral rights are best analyzed with the component concepts instead of the cluster concept. Eliminativism is therefore preferable to competing accounts of personal identity because the former is better suited for moral theory. Among the advantages are the ability to: attribute responsibility to group agents without calling them persons, make sense of our conflicting demonstrations of self-concern without taking them as evidence for conflicting theories of personal identity, and attribute moral rights to entities who fail to meet traditional criteria for personhood but who are nonetheless entitled to moral respect.

The paper reviews the arguments for and against a number of criteria for event identity. The proliferation of such criteria in the 1970’s raises the question of how one is to choose between them. Eight adequacy conditions, whose own adequacy has been argued for elsewhere, are determined to be insufticient for deciding among the criteria. Some concluding remarks about the role of the adequacy conditions and the problem of choosing a criterion are offered. Finally, questions about (...) the nature of and role of an identity criterion are raised. (shrink)

Talk of gender identity is at the core of heated current philosophical and political debates. Yet, it is unclear what it means to have one. I examine several ways of understanding this concept in light of core aims of trans writers and activists. Most importantly, the concept should make good trans people’s understanding of their own gender identities and help understand why misgendering is a serious harm and why it is permissible to require information about people’s gender identities in (...) public life. I conclude that none of the available accounts meets these essential criteria, on the assumption that the gender norms of femininity and masculinity are unjustified. But we can, and should, pursue the feminist project without “gender identity”. Such feminism can include trans people because it is possible to account for the specific harm of misgendering without assuming a claim to the recognition of our gender identities. I conclude that we should eliminate the concept of “gender identity.” To understand the phenomena that are putatively captured by “gender identity,” we are better off employing other concepts, such as “sexual dysphoria,” (assigned or aspirational) “gender roles,” and (internalised or endorsed) “gender norms”. These concepts can usefully replace “gender identity” in an individual evaluation of each of the trans people’s claims to inclusion into particular spaces. (shrink)

Four-dimensionalists offer a unified picture of various puzzles about identity over time, including the puzzle of fission, the puzzle of constitution and the puzzle of undetached parts. What unifies the four-dimensionalist approaches to these puzzles is the possibility of temporal overlap—the possibility for distinct continuants to share a common temporal part, or stage. I claim that the unified picture is inconsistent, if there are informative criteria of identity over time. I will show that while temporal overlap is (...) compatible with four-dimensionalist criteria of diachronic composition, temporal overlap is incompatible with any four-dimensionalist criteria of diachronic identity.

Available from UMI in association with The British Library. Requires signed TDF. ;In this thesis I argue that we ought to accept some version of the Analysis view--the view that the identity of a person over time can be analysed in terms of physical and/or psychological continuities. I also argue that there is no sense in which we ought to be ontological reductionists about persons--a person is an essentially embodied, irreducible, entity whose identity over time is analysable in (...) terms of physical and psychological continuities. ;I argue that any plausible theory of personal identity over time is a best-candidate theory, which implies that the identity of a person over time can be extrinsically determined. Some philosophers find this consequence absurd; but I claim that they have no good reason to. I also show how reference to the extrinsicness of identity features in a powerful argument for Derek Parfit's thesis that identity is not "what matters". Finally, I argue that there are plausible counter-examples to all versions of the Physical and Psychological Criteria of personal identity, and that we ought to accept a version of the Mixed Criterion which acknowledges the importance of both sorts of continuity, but which assigns greater weight to the relation of psychological continuity.

Questions of identity such as ‘Who am I?’ are often answered by appeals to one or more affiliations with a specific nation (citizenship), culture, ethnicity, religion, etc. Taking as given the idea that identity over time—including identification and re-identification—for objects of a particular kind requires that there be criteria of identity appropriate to things of that kind, I argue that citizenship, as a ‘collectivist’ concept, does not generate such criteria for individual citizens, but that the (...) concept person—which specifies the kind of entity that I am—does generate such criteria. Confusion on this point has led some writers on citizenship to equivocate between identity for individuals and what is properly called self-determination in terms of their group affiliations and commitments. In the second part of the paper, I articulate and defend a relational view of personhood, and argue that it provides adequate grounding for morality in general, and moral education in particular. While not denying the value of civics or citizenship education, the link between morality and citizenship is derivative, at best. Finally, I examine the implications of a relational conception of personhood for the specific context of schools and classrooms, arguing that this conception is appropriately represented when the classroom functions as a community of inquiry, in which each member is encouraged to see her/himself as one among others. Drawing on the theory and practice of Philosophy for Children, I conclude with a call to reunite citizenship and moral education with their philosophical roots. (shrink)

There is a spectrum of identities: from the mathematical, through cases where specific criteria matter, to the complex or intuitive cases where we can recognize identity but don't know what the criteria should be. In a series of essays by senior figures in the sciences and humanities, this book examines what identity means across a number of academic disciplines. Topics range from mathematics, through the rules of recognition in biology and the law, to comprehending the individual (...) in the visual, performing and literary arts, and ultimately to notions of the philosophy of existence. Using the theme of identity to make new interdisciplinary connections, the contributors offer interested readers a glimpse into their specialist subjects and suggest new ways for students and scholars to think about identity in relation to their own work.

According to one argument for Animalism about personal identity, animal , but not person , is a Wigginsian substance concept—a concept that tells us what we are essentially. Person supposedly fails to be a substance concept because it is a functional concept that answers the question “what do we do?” without telling us what we are. Since person is not a substance concept, it cannot provide the criteria for our coming into or going out of existence; animal , (...) on the other hand, can provide such criteria. This argument has been defended by Eric Olson, among others. I argue that this line of reasoning fails to show Animalism to be superior to the Psychological Approach, for the following two reasons: (1) human animal , animal , and organism are all functional concepts, and (2) the distinction between what something is and what it does is illegitimate on the reading that the argument needs.

This paper evaluates six contenders which might be invoked by essentialists in order to meet Quine’s challenge, viz., to provide necessary and sufficient conditions for the crossworld identity of individuals: (i) an object’s qualitative character; (ii) matter; (iii) origins; (iv) haecceities or primitive non-qualitative thisness properties; (v) “world-indexed properties”; and (iv) individual forms. The first three candidates, I argue, fail to provide conditions that are both necessary and sufficient for the crossworld identity of individuals; the fourth and fifth (...) criteria are open to the charge that they do not succeed in meeting Quine’s demand in an explanatorily adequate fashion. On balance, then, individual forms, or so I propose, deserve to be taken very seriously as a possible response to Quine’s challenge, especially by neo-Aristotelians who are already committed to a hylomorphic conception of composite concrete particular objects for other reasons. Theorists who also accept a non-modal conception of essence, i.e., a conception according to which essence is not reducible to modality, in addition face the further difficult task, over and above what is required to meet Quine’s challenge, of having to explain how an object’s de re modal profile in some way follows from facts about its essence. Haecceities and world-indexed properties, as I indicate, are unlikely to be of much help with respect to this second challenge, while the forms of hylomorphic compounds are in fact well-suited for this purpose.

ABSTRACT The target article uses the metaphysics of properties to make its meta-ethical claims. This comment discusses two general points in the metaphysics of properties. The first point has to do with the conditions for property identity. Philosophers who accept the existence of properties have proposed a variety of criteria for their identity. The standard Broome applies is medium coarse. Other standards for property identity could be evaluated for their appropriateness for addressing questions in the metaphysics (...) of ethics. Use of a formalized theory of properties might help in such an evaluation. The second point has to do with Broome’s suggestion of a distinction between a property and a reified property. A suggestion will be offered for a range of ways such a distinction could be filled out using the resources of a formalized theory of properties and objects. Objects will be proposed that could serve as Broome’s reified properties. (shrink)

There is a category of objects such that for any two occurrences of an object in that category, Establishing the highest degree of their qualitative identity will not be sufficient to establish that the object involved is one and the same.

'identity' includes a family of relations and is wrongly restricted to what satisfies leibniz's law: diachronic and strict identity are related since the criteria of the former are just the criteria of continuity of stages of the strictly identical continuant. A general account can be given in terms of the preservation of a weighted preponderance of properties of the stages. Puzzle cases arise because of contextual shifts in the weightings assigned; in the case of persons this (...) is particularly clear because of change of emphasis between mental and physical, Both of which classes of predicate are applicable.

Fictional ersatz realism is the metaphysical stance that abstract fictional entities exist and are dependent on fiction and literary practices. Everett tackled the position of ersatz realism by claiming that the ersatz realist cannot provide an identity criterion for fictional entities that does not imply a contradiction. Although Woodward proposed a defense to Everett's argument, I will argue that ersatz realism is no tenable position, as it still cannot provide an adequate identity criterion. To establish this result, I (...) will provide a base frame for identity criteria available to the ersatz realist. Afterwards, I will show that to any identity criterion the ersatz realist may propose there is a story such that a fictional entity corresponding to this story is not self-identical, imposing a contradiction to the metaphysical account of ersatz realism.

This book examines the different conceptions of the individual that have emerged in recent new approaches in economics, including behavioral economics, experimental economics, social preferences approaches, game theory, neuroeconomics, evolutionary and complexity economics, and the capability approach. These conceptions are classified according to whether they seek to revise the traditional atomist individual conception, put new emphasis on interaction and relations between individuals, account for individuals as evolving and self-organizing, and explain individuals in terms of capabilities. The method of analysis uses (...) two identity criteria for distinguishing and re-identifying individuals to determine whether these different individual conceptions successfully identify individuals. Successful individual conceptions account for sub-personal and supra-personal bounds on single individual explanations. The former concerns the fragmentation of individuals into multiple selves; the latter concerns the dissolution of individuals into the social. The book develops an understanding of bounded individuality, seen as central to the defense of human rights. (shrink)

Putnam raises two objections against the token-identity theory in his _Dewey Lectures. (1) Token-physicalism invokes a mysterious or _sui generis concept of identity between mental and physical event tokens; (2) The theory suffers from explanatory failure because it cannot individuate mental events using physical criteria. I argue that the first claim is false, since Davidson adopts the same criterion of identity Quine employs for ordinary objects which invokes a concept of identity we understand clearly enough. (...) I then show that Putnam's second complaint is an extravagant demand that needs not be answered and is at odds with his own direct realism. (shrink)

Some relations - like supervenience and composition - can appear very much like identity. Sometimes, the relata differ only in modal, or modally-involved features. Yet, in some cases, we judge the pairs to be identical (water/H2O; Hesperus/Phosphorus), while in others, many judge one of the weaker relations to hold (c-fiber firing/pain; statues/lumps). Given the seemingly same actual properties these pairs have, what can justify us in sometimes believing identity is the relation, and sometimes something weaker? I argue that (...) it can only be knowledge of differences of individuative criteria that we know a priori because they are built into the meanings of the words/concepts involved. Possible metaphysical conclusions are considered. (shrink)

My aim in this paper is to carve out a political understanding of the Muslim identity. The Muslim identity is shaped within a religious mold. Inseparable from this religious understanding is a political one that is valuable in its own right in order to secure any sustainable possibility of participating politically as Muslims within a democratic liberal democracy, such as the United States. Here I explore not the historical or theological formation of the Muslim identity, rather a (...) metaphysical understanding of it, in order to mobilize politically while avoiding the traps of essentialism. I begin with a brief overview of the early understandings of the term “identity politics” in the United States. Moving beyond interest-based movements I explore María Lugones' particular understanding of the self as multiplicitous. I then offer examples of the Muslim identity within the context of a social movement and individualist claims, in order to draw out the political aspects of the Muslim identity. In the final section I argue that the theological criteria that define “who counts as a Muslim” is a crucial aspect of how many Muslims may understand their identity as Muslims. However, I claim that in order to avoid the traps of marginalization of Muslim minorities, one must understand oneself as a multiplicitous political agent and that, furthermore, such an understanding is not at odds with Islam or one's own understanding of their identity as Muslim.

This is a strikingly original, rich, and trenchant study. Its point of departure is the notion of discrimination, which is shown to illuminate a range of topics in metaphysics and epistemology, including subjectivity, observationality, sorites paradoxes, and identity criteria. A central problem involves the phenomenal character of experience. We are intuitively tempted to say that character is subjective in the sense that distinct characters must be discriminable. This seems to imply that matching experiences--that is, experiences which are indiscriminable (...) in character--must have the same character. We find familiar cases, however, in which the experiences x and y match, and the experiences y and z match, but x and z do not match. Williamson defends the subjectivity of character by arguing that a pair of characters may be indiscriminable as presented by one pair of experiences but discriminable as presented by another pair of experiences. Hence the indiscriminability of characters is indeed sufficient for their identity, which makes characters subjective, but the matching of experiences is not sufficient for the experiences' having the same character.

The inclusion of girls and women in sport at all levels depends on single sex categories for most sports from puberty onwards, because of the biological differences between the sexes. Most sport is, by definition, competitive; involving invasion games, teams, leagues, races, competitions and sometimes rankings, from foundation to excellence. Girls and women are underrepresented, particularly in traditional sport, as recognised by the UK Sports Councils and most governing bodies of sport. This paper uses feminist philosophy: Lister on androcentric citizenship, (...) and Fraser on justice as balance, framing, recognition, representation and redistribution. It investigates the impact on the inclusion of girls and women, of eligibility policies adopting ‘self-identification of gender’ guidelines for the inclusion of transgender people in sport, at participation rather than elite levels. It explores fairness and equality as incorporated in law in the 2010 Equality Act in Britain, and contributes to ‘equality evidence’ available to the UK Sports Councils and GBS. These bodies are charged with developing fair and inclusive evidence-based eligibility criteria, in sports participation settings, for both girls and women, and transgender people. (shrink)

The purpose of this paper is to test the contemporary concept of biological species against some of the problems caused by treating species as spatiotemporally extended entities governed by criteria of persistence, identity, etc. After outlining the general problem of symmetric division in natural objects, I set out some useful distinctions (section 1) and confirm that species are not natural kinds (section 2). Section 3 takes up the separate issue of species definition, focusing on the Biological Species Concept (...) (BSC). Sections 4 and 5 examine the matter of species identity over space and time respectively, as determined by the BSC. Both gradualistic and punctuated equilibrium models of speciation are discussed. In section 6 I argue that the BSC fails to determine adequate criteria for dealing with certain kinds of speciation. Section 7 moves speculatively beyond the BSC to a brief examination of alternatives. (shrink)

In decision-making based on multiple criteria, situations may arise where agents find their options to be neither better than, worse than nor equal to each other with respect to the relevant criteria. How, if at all, can a justified choice be made between such options? Are the options incomparable? This article explores a hypothetical case that illustrates how such a situation can arise in an environmental context; more specifically, it considers the deliberations of an imagined ‘ethics committee’ as (...) it struggles to decide whether or not a deep-sea mining project should be allowed to proceed. I argue that the case is best understood as involving options that are comparable in the sense of being ‘on a par’. Working out from a discussion of Ruth Chang's ‘self-governance’ theory of choice in cases of parity, I suggest that, in the environmental context, the idea of choices expressing a moral identity may lead us in the direction of a plausible solution to these particularly challenging cases.

My real intention, however, is not to praise Wilson but to harry him. His argument seeks to give us substances, concrete individuals, without the prop of a Lockean substrate and without the Humean stigma of reducibility to bundles of properties. Wilson explicitly aims at doing justice in his doctrine to our rather hazy ordinary beliefs about individuals. He writes: "Goodman's language is remote from our ordinary ways of looking at the world and our ordinary ways of speaking about it. At (...) the risk of being subsequently hoist with my own petard I should be inclined to suggest that these ordinary ways should be treated with respect and, if possible, vindicated. At any rate we may quite properly be suspicious of gratuitous and unnecessary departures from our common sense views." Here Wilson stands in the tradition of Aristotle's attempt to resolve puzzles about common sense concepts and so to forestall the motivation for a revisionary metaphysics like Plato's. And much more blatantly than does the De Anima account of souls as simply the forms of organisms, Wilson's treatment of substances succeeds in distorting important differences in our ways of thought about personal identity and about non-personal identity. Without ignoring the fact that non-personal individuals themselves form a heterogeneous class from an identifier's point of view, I do suggest that certain identification puzzles about people and near-people tend to diverge sharply from those about things and near-things. Anthony Flew has brought out several quite peculiar difficulties concerning 'same person' in a paper on 'Locke and Personal Identity'. For instance, the problem of finding criteria for personal identity, as Flew commends Locke for showing, is quite crucial to questions about the concepts of fair reward and punishment and about the notion of 'survival.' Recall the obvious: it is people and near-people that we worry about both as having the possibility of a reincarnation or hereafter--be it theological, theosophical or parapsychological--and as being the proper recipients of praise and blame. Insofar as we worry about dogs, ships and ideals in these respects they are treated as what I call 'near-people.' Insofar as people do not invite such queries they are 'near-things.' Locke's probe into the logical grammar of personal identity points to common sense intuitions about individuals which Wilson here and elsewhere has contrived to slur over. Of course such apparent intuitions may lead to error or even nonsense, but let us for the moment cleave to Wilson's intention of vindicating them. (shrink)

Properties and concepts are similar kinds of thing in so far as they are both typically understood to be whatever it is that predicates stand for. However, they are generally supposed to have different identity criteria: for example, heat is the same property as molecular kinetic energy, whereas the concept of heat is different from the concept of molecular kinetic energy. This paper examines whether this discrepancy is really defensible, and concludes that matters are more complex than is (...) generally thought. The distinction between canonical and non-canonical designators, as applied to such entities as propositions, properties and concepts, is examined, as are causal realist accounts of the semantics of such terms as ‘electricity’ and ‘mass’.

In philosophy, the criteria for personhood (PH) at a specific point in time (synchronic), and the necessary and sufficient conditions of personal identity (PI) over time (diachronic) are traditionally separated. Hence, the transition between both timescales of a person's life remains largely unclear. Personal habits reflect a decision-making (DM) process that binds together synchronic and diachronic timescales. Despite the fact that the actualization of habits takes place synchronically, they presuppose, for the possibility of their generation, time in a (...) diachronic sense. The acquisition of habits therefore rests upon PI over time; that is, the temporal extension of personal decisions is the necessary condition for the possible development of habits. Conceptually, habits can thus be seen as a bridge between synchronic and diachronic timescales of a person's life. In order to investigate the empirical mediation of this temporal linkage, we draw upon the neuronal mechanisms underlying DM; in particular on the distinction between internally and externally guided DM. Externally guided DM relies on external criteria at a specific point in time (synchronic); on a neural level, this has been associated with lateral frontal and parietal brain regions. In contrast, internally guided DM is based on the person's own preferences that involve a more longitudinal and thus diachronic timescale, which has been associated with the brain's intrinsic activity. Habits can be considered to reflect a balance between internally and externally guided DM, which implicates a particular temporal balance between diachronic and synchronic elements, thus linking two different timescales. Based on such evidence, we suggest a habit-based neurophilosophical approach of PH and PI by focusing on the empirically-based linkage between the synchronic and diachronic elements of habits. By doing so, we propose to link together what philosophically has been described and analyzed separately as PH and PI. (shrink)

Erikson is Professor of Human Development at Harvard, a psychoanalyst, and the author of the widely influential books, Young Man Luther, and Childhood and Society. What is the relevance of his latest book to philosophy? One answer is that Erikson deals with several concepts of personal identity which philosophers will recognize as corresponding to historical philosophic positions. He does not choose between these disparate views, but correlates them, treating each as partial, and learning about his complex subject from the (...) habits of syntax appropriate to each. Erikson divides personal identity into the "I," the "selves," and the "ego," on the grounds that these terms provide a way to distinguish roles and "counterplayers" of various functionings of human personality. We need these various terms to designate identity as viewed from without and from within. Erikson's "selves" are what the "I" reflects on when it views the body, the personality, or the social roles to which it is attached. The counterplayers of the "selves" are the "others" of Existentialism. Erikson's reflective "I," like the subject of Descartes' cogito, is "the center of awareness in a universe of experience in which I have a coherent identity... am in possession of my wits and able to say what I see and think." With Descartes, Erikson finds the unique counterplayer to the "I" in the Deity; the repository of the vitality which is being affirmed of itself in each awareness of the "I." Erikson's "ego" corresponds to the Self of Hume's Treatise, undiscoverable beneath its particular perceptions. The "ego" is necessarily unconscious; we are aware of its work but never of it. As of Hume's self, we can say of it that it has the task of turning passive into active, screening and organizing the impositions of the internal and external environment in such a way that they bring about volitions. Like Hume, Erikson feels philosophers and psychologists have "created nouns such as the 'I' or the 'self', making imaginary entities out of a manner of speaking" and that we would be mistaken to give ontological status to these particles. Perhaps Erikson would accept a statement of the contemporary philosophical form: "The several designations of 'selves', etc., are instrumental in explaining complex personal identity feelings or events." In other parts of the book Erikson uses William James as an example of creative identity, discusses the concept of "negative identity", and in the last three chapters discusses aspects of personal identity in the disequilibrium of the young, the races, and women. The book contains Erikson's writings on identity over a twenty-year period. However, in areas of common interest to psychoanalytic theory and philosophy, the requirements of Erikson's clinical work have suggested relationships between concepts different from the relationships often assumed by philosophers. Thus, on personal identity, criteria of ideological soundness of a society, and the determinants of empirical perception, the addition of Erikson's insights may give the philosopher a multidimensional glimpse of the field wherein he labors.--M.

I identify a class of arguments against multiple realization (MR): BookofSand arguments. The arguments are in their general form successful under reasonably uncontroversial assumptions, but this, on the other hand, turns the table on identity theory: If arguments from MR can always be refuted by BookofSand arguments, is identity theory falsifiable? In the absence of operational demarcation criteria, it is not. I suggest a parameterized formal demarcation principle for brain state/process types and show how it can be (...) used to identify previously unconsidered contenders for evidence for MR, e.g., binary classification, division, and sorting. For these to be actual instances of MR, the corresponding psychological kinds must be verifiably, relevantly similar. I also briefly discuss possible linguistic, behavioral, and experimental demarcation criteria for psychological kinds. (shrink)

Following insights from the New Theory of Reference, it has become widely accepted that theoretical identities like ‘water = H2O' are necessary. However, some have challenged this claim. I propose yet another challenge in the form of a sceptical argument. The argument is based on the contention that the necessity of theoretical identities is dependent upon criteria of identity. Thus, a theoretical identity is necessary given one criterion of identity but contingent given another. Since we do (...) not know which criteria of identity in fact obtain, it follows that, for all we know, theoretical identities may not be necessary. (shrink)

Quine has persuasively shown that the empiricist "dogma of reductionism", which is the belief that each meaningfiil statement of science can be reduced to statements about immediate sense experience, must be abandoned. However, Quine's methodology of ontology seems to incorporate an analogous physicalistic dogma according to which the identity conditions of each scientifically respectable sort of abstract objects can be reduced to the identity conditions of physical objects. This paper aims to show that the latter dogma must be (...) abandoned, too. In section 1, the reductionist methodology underlying Quine's prescript "No Entity without Identity" is reconstructed in detail. In section 2 and 3, this methodology is criticized on the ground that Quine's individuation of sets offendsagainst the reductive Criteria of adequacy for individuations that are presupposed by his criticism of the ontological recognition of intensional objects. Finally, in section 4 an alternative holistic conception of individuation is outlined. (shrink)

Ethical theories must include an account of the concept of a person. They also need a criterion of personal identity over time. This requirement is most needed in theories involving distributions of resources or questions of moral responsibility. For instance, in using ethical theories involving compensations of burdens, we must be able to keep track of the identities of persons earlier burdened in order to ensure that they are the same people who now are to receive the compensatory benefits. (...) Similarly, in order to attribute moral responsibility to someone for an act, we must be able to determine that that person is the same person as the person who performed the act. Unfortunately, ethical theories generally include a concept of a person and criteria of personal identity either as notions implied or presupposed by the already worked out theory, with little or no argument given in support of them. But both approaches are unsatisfactory, for each runs the risk of ignoring certain fundamental features of the way persons actually are. What is needed first is a plausible metaphysical account of persons and personal identity to which an ethical theory might then conform and apply. Derek Parfit has attempted to provide such an account in Reasons and Persons, where he argues for what he calls the reductionist view of persons and personal identity and then attempts to show how such a conception provides a metaphysical background that lends important partial support to utilitarianism. 1 But Parfit’s metaphysical view is neutral between two possible conceptions of personhood, and utilitarianism presupposes the truth of the more radical of the two conceptions, which precludes the possibility of there being a class of goods crucial to any plausible ethical theory. Utilitarianism thus presupposes a wildly implausible conception of persons, and so is itself implausible. (shrink)

It is not the case that there is only one literal sense of “same person.” When presented in different contexts, “she is/is not the same person” can have different answers concerning the same entity or set of entities across the same period of time. This is because: Persons are composed of many parts, and different parts have different persistence conditions. This follows from a reductionist view of the self. When we ask about sameness of persons, or “personal identity,” we (...) are asking because of certain practical concerns. Different concerns will look to the persistence of different parts of the person for criteria of sameness. No single criterion of sameness tracks all concerns. By combining reductionism with contextualism, the disparate answers to the personal identity question can be clarified without losing the practical concerns motivating them. (shrink)

This paper examines Charles Taylor’s claim that personal identity is a matter of strong evaluations. Strong evaluations are in this paper analyzed as stable preferences, which are strongly identified with and which are based on qualitative distinctions concerning the non-instrumental value of options. In discussing the role of strong evaluations in personal identity, the focus is on "self-identity", not on the criteria of personhood or on the logical relation of identity. Two senses of self-identity (...) can be distinguished: identity as practical orientation and identity as self-definition in a more encompassing sense. The former consists of one’s strong evaluations only, the latter is a more comprehensive notion, in which strong evaluations have a double role. Strong evaluations are first of all directly a constituent of self-definitions, and secondly, self-definition with respect to other features proceeds in the light of the strong evaluations. (shrink)

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)
