This study will explore the Enlightenment conception of the individual of reason, its attempted formulations in actor biographies, and its ultimate denial by the reality of human identity as multiple, fluid, and dialogical. Such fluidity sought to overcome the marginal status of the stage player through the embodiment of rational models of personality. Some stage celebrities, most notably David Garrick, were offering themselves as public models of identity for the new age of reasoned discourse. This involved the presentation (...) before the public of stage performers as fully realized individuals. However, the unavoidable problem was that presenting an individual, even a renowned stage star, as a living paradigm of the enlightened person of reason would prove elusive. Aside from the inherent contradiction of locating any perfected stereotype in an actual person, the qualities making an individual in full conformity to his or her “reason” did not match the particular cultural qualities demanded for a successful eighteenth-century middle-class Englishman or Englishwoman. Nonetheless, by the last quarter of the eighteenth century, significant advances were made both within the particular profession of acting and before the onstage and offstage public. The acting profession was moving quickly and for the first time in England away from its marginalized status to offer respected agents for cultural change. The new genre of actor biographies as well contributed to this more fully realized formulation of the modern individual. (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.

In the philosophy of science, identity over time emerges as a central concern both as an ontological category in the interpretation of physical theories, and as an epistemological problem concerning the conditions of possibility of knowledge. In Reichenbach and subsequent writers on the problem of indistinguishable quantum particles we see the return of a contrast between Leibniz and Aquinas on the subject of individuation. The possibility of rejecting the principle of the identity of indiscernibles has certain (...) logical difficulties, leading us inexorably from ontology into epistemology. For the epistemological problem we attend to the differences that emerged between the (neo-)Kantian and logical empiricist traditions, also saliently displayed in Reichenbach's writings. After examining the contrast between Kant's and Leibniz's conceptions of empirical knowledge, specifically with respect to the irreducibility of spatiotemporal determinations, we explore an application of a neo-Kantian view to the same problem of indistinguishable quantum particles.

What am I? And what is my relationship to the thing I call ‘my body’? Thus each of us can pose for himself the philosophical problems of the nature of the self and the relationship between a person and his body. One answer to the question about the relationship between a person and the thing he calls ‘his body’ is that they are two things composed of the same matter at the same time (like a clay statue and the (...) piece of clay which presently constitutes it). This is the ‘constitution view’. In this paper we give a novel overview of the literature on personal identity, the constitution view, and surrounding topics. (shrink)

According to reductionists about agency, an agent’s bringing something about is reducible to states and events involving the agent bringing something about. Many have worried that reductionism cannot accommodate robust forms of agency, such as self-determination. One common reductionist answer to this worry contends that self-determining agents are identified with certain states and events, and so these states and events causing a decision counts as the agent’s self-determining the decision. In this paper, I discuss Michael Bratman’s well-known identification reductionist theory (...) and his general strategy of grounding an agent’s identification at a time in the agent’s identity over time. I develop two constraints that an adequate identification reductionist theory must satisfy, argue that Bratman’s theory cannot satisfy both, and show that his general strategy for grounding an agent’s identification at a time in the agent’s identity over time is without merit.

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)

Identity-Over-Time has been a favorite subject in the literature concerning Thomas Aquinas. Aquinas addresses this issue in many discussions, including especially the identity of material things and artifacts, the identity of the human soul after the corruption of body, the identity of the body of Christ in the three days from his death to his resurrection and the identity of the resurrected human body at the end of time. All these discussions have (...) a point in common: they lead Aquinas to raise the question of Identity-Over-Time with respect to things that fully exist in act, i.e., things that possess an identity of their own and change some of their parts or properties over time while continuing to be what they are. In this article, I investigate this topic from a different angle, considering the case of the trans-temporal identity of things that do not yet have an identity of their own or fully exist in act. The case at stake is that of the identity of the human embryo through the process of human generation. It is a puzzle that Aquinas seems to have some difficulties to solving, given his account of human embryogenesis as a process that alternates generations and corruptions of the subject. At the same time, though, Aquinas does not want to renounce the idea that the subject of generation must be numerically one and the same throughout all the process. In order to solve this puzzle, Aquinas seems to suggest distinguishing the identity of the subject from the identity of its matter and/or form. At given conditions, a thing can even change its matter and form while continuing to be the same thing in number. Specifically, the numerical identity of the subject of generation is justified by the identity entailed by the metaphysical notions of potency and act. (shrink)

The analysis of personal identity over time (personal persistence) in terms of properties of the first-person perspective has been neglected for quite a while. However, there seems to be an interesting relation between experiential features on the one hand and the notion of personal persistence on the other hand. This idea is famously spelled out in an argument introduced by Barry Dainton (2000; 2005; 2008), according to which diachronic personal persistence con- sists in experiential continuity (stream of (...) consciousness). This paper challenges one central claim of the argument, whose main target is to ward off the threat of factual interruptions in the stream of consciousness. It will be objected that this problem cannot be properly solved. However, the relevance of experiential features to personal persistence can be shown if one leaves behind the question of criteria of personal identity over time and instead turns to the question of what it means to have a sense of self-identity over time. It will be argued that not only experiential continuity but also experiential features of episodic memory characterise the sense of self-identity over time. (shrink)

This essay explores what is at stake while considering the change and identity of objects over time. Philosophers worry about an object having incompatible properties in part due to the fact that it is ruled out by Leibniz's Law. They have preferred to hold on to Leibniz's Law and to find some other way to resolve the problem of an object's changing its properties over time. The chapter examines three accounts of how objects change (...) class='Hi'>over time without violating Leibniz's Law: endurance, perdurance, and exdurance. The chapter finally provides a brief discussion of something that has been much neglected in the literature on persistence, namely, mixed theories. (shrink)

ABSTRACTThis paper studies Antoine Le Grand's account of organic identity over time in human bodies. In response to Aristotelian critics who argued that the Cartesian rejection of the Aristotelian ontology of matter and form had put in jeopardy the diachronic identity of material substances in general and of living bodies in particular, Le Grand argued that the identity over time of the human body could be accounted for without the traditional notions of matter (...) and form. The paper shows how he drew on both the Cartesian metaphysics of mind and body and contemporary views on human anatomy and organic generation to develop a unique account of bodily identity over time in human animals.

We ordinarily believe that the inhabitants of the world - including ourselves - persist over time. Such an idea, however, has puzzled philosophers for centuries. How can we change and still be the same? More specifically, is there any constitutive condition of our identity over time? And if so, does this condition involve mental aspects, physical aspects, or something else? Or is rather personal identity primitive and unanalyzable, so that our persistence is nothing but (...) a brute fact? This volume is a collection of new essays from leading figures in the field analyzing the persistence of persons and the criteria of personal identity over time. It presents an extensive discussion of the most relevant views on personal identity in contemporary metaphysics and provides new treatments of the constitutive conditions of personal persistence.

Dissociative experiences have been associated with diachronic disunity. Yet, this work is in its infancy. Dissociative identity disorder is characterized by different identity states reporting their own relatively continuous sense of self. The degree to which patients in dissociative identity states experience diachronic unity has not been empirically explored. This study examined the degree to which patients in dissociative identity states experienced diachronic unity. Participants were DID adults assessed in adult and child identity states, adults (...) with a psychotic illness, adults from the general population, children from the general population and adults imagining themselves as children. They completed the Diachronic Disunity Scale, the Dissociative Experiences Scale, and the Self-Concept Clarity Scale. Diachronic disunity was not limited to psychiatric groups, but evident to some degree in all adult and child samples. The DID adult sample experienced more dissociation and self-confusion than the psychosis and adult comparison groups, but did not differ on the diachronic measure. DID patients in their child identity states and child comparisons showed disunity and were significantly different from child simulators, who showed relatively more unity. Results suggest that DID patients in either adult or child dissociative identity states, like those in other samples, do not universally experience themselves as having a consistent sense of self over time.

The aim of the paper is to shed light on the problem of identity of particulars over time within the framework of Quinean analysis. First, it focuses on the relationship between essential and accidental property changes as a criterion for distinguishing cases when objects retain their identity from cases when they loose it. In this part it is shown, that a coherent distinction between essential and accidental properties is problematic. Quinean approach indicates that we do not (...) need to look for any kind of criterion of identity of particulars over time. Hence, the conclusion is that the identity of particulars over time should not be viewed as a problem of how to understand the concept of identity, but rather as a problem of how to understand certain general concepts, i.e. how to individualize certain parts of the world by the use of certain general terms.

The existence and importance of supervenience principles for identity across times and worlds have been noted, but insufficient attention has been paid to their precise nature. Such attention is repaid with philosophical dividends. The issues in the formulation of the supervenience principles are two. The first involves the relevant variety of supervenience: that variety is global, but there are in fact two versions of global supervenience that must be distinguished. The second involves the subject matter: the names “identity (...) over time” and “identity across worlds” are misnomers, for in neither case is identity at issue. The philosophical dividends then follow. Nathan Salmon’s argument that identity over time needs no “grounds” in matters of qualitative fact can be answered, as can an argument offered by many, that coincident objects would require objectionably ungrounded differences in identities across times and worlds.

The temporal unity of the self cannot be accounted for by the continuity of causal, factual, or contiguous relations between independently definable mental events, as proposed by Locke and Parfit. The identity of the self over time is normative: it depends on the institutional context of social rules external to the self that determine the relationship between past commitments and current responsibilities. (2005).

One of the topics that often comes up in ethical discussions of deep brain stimulation (DBS) is the question of what impact DBS has, or might have, on the patient’s self. This is often understood as a question of whether DBS poses a “threat” to personal identity, which is typically understood as having to do with psychological and/or narrative continuity over time. In this article, we argue that the discussion of whether DBS is a “threat” to continuity (...) over time is too narrow. There are other questions concerning DBS and the self that are overlooked in discussions exclusively focusing on psychological and/or narrative continuity. For example, it is also important to investigate whether DBS might sometimes have a positive (e.g. a rehabilitating) effect on the patient’s self. To widen the discussion of DBS, so as to make it encompass a broader range of considerations that bear on DBS’s impact on the self, we identify six features of the commonly used concept of a person’s “true self”. We apply these six features to the relation between DBS and the self. And we end with a brief discussion of the role DBS might play in treating otherwise treatment-refractory anorexia nervosa. This further highlights the importance of discussing both continuity over time and the notion of the true self. (shrink)

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)

According to most contemporary philosophers, the Indiscernibility of Identicals is obviously true. We might therefore expect earlier philosophers to endorse it. But I will use a puzzle about identity over time to argue that Descartes would reject it.

Brian Hedden defends a radical view about the relationship between rationality, personal identity, and time. On the standard view, personal identity over time plays a central role in thinking about rationality, because there are rational norms for how a person's attitudes and actions at one time should fit with her attitudes and actions at other times. But these norms are problematic. They make what you rationally ought to believe or do depend on facts about (...) your past that aren't part of your current perspective on the world, and they make rationality depend on controversial, murky metaphysical facts about what binds different instantaneous snapshots into a single person extended in time. Hedden takes a different approach, treating the relationship between different time-slices of the same person as no different from the relationship between different people. On his account, the locus of rationality is the time-slice rather than the temporally extended agent. This impersonal, time-slice-centric approach to rationality yields a unified approach to the rationality of beliefs, preferences, and actions where what rationality demands of you is solely determined by your evidence, with no special weight given to your past beliefs or actions.

Spinoza claims that a person's body can be numerically identical over time, despite changes in its size, shape, and speed. This chapter argues that he would reject the Indiscernibility of Identicals. The Indiscernibility of Identicals is often taken to have profound implications for one's view of change. Spinoza seems to deny the existence of times, because he similarly classifies them as “beings of reason”. As Spinoza understands instantiation, whenever a property is instantiated by an object, it metaphysically depends (...) on that object. As Spinoza understands instantiation, the existence of a property causally depends on whatever instantiates it. Spinoza says that the mind, and therefore the body, can “undergo great changes, and pass to a greater, to a lesser perfection”. Spinoza is committed to saying that all bodies are capable of change, even the shortest‐lived. Spinoza can deny that the non‐identity of Downstairs Peter and Upstairs Peter is due to their conflicting properties. (shrink)

Aquinas, Ockham, and Burdan all claim that a person can be numerically identical over time, despite changes in size, shape, and color. How can we reconcile this with the Indiscernibility of Identicals, the principle that numerical identity implies indiscernibility across time? Almost all contemporary metaphysicians regard the Indiscernibility of Identicals as axiomatic. But I will argue that Aquinas, Ockham, and Burdan would reject it, perhaps in favor of a principle restricted to indiscernibility at a time.

Tracking persons, that is, determining that a person now is or is not a specific earlier person, is extremely common and widespread in our way of life and extremely important. If so, figuring out what we are tracking, what it is to persist as a person over a period of time, is also important. Trying to figure this out will be the main focus of this chapter.

Several recent papers dealing with Plato's position on the imperfection of the phenomenal world draw heavily on the differences between two kinds of predicates in order to show the following: In the middle dialogues, Plato posits Forms only as referents of what the writers call incomplete predicates.

When interpreters ignore the differences between these kinds of predicates, they ascribe too radical a view regarding the imperfection of the phenomenal world to (...) the middle dialogues.

This article charts the feminist perspectives that have come out of the author’s thinking on the dance performance text Human Sex and how this has informed her own feminism. In doing so, the author argues that a feminist agenda is shifting and dynamic but also reliant upon prior readings and interpretations that provide the point of reference for a departure to other readings and perspectives. Using autobiographical material, the author highlights the importance of considering the personal histories of subject-hood that (...) influence a feminist consciousness and how these are the condition of possibility for making other readings. To demonstrate the shifting character of identity over time, she engages in different readings of Human Sex through the work of feminist theorists Sara Ahmed, Judith Butler and Peggy Phelan.

The family of theories dubbed ‘luck egalitarianism’ represent an attempt to infuse egalitarian thinking with a concern for personal responsibility, arguing that inequalities are just when they result from, or the extent to which they result from, choice, but are unjust when they result from, or the extent to which they result from, luck. In this essay I argue that luck egalitarians should sometimes seek to limit inequalities, even when they have a fully choice-based pedigree (i.e., result only from the (...) choices of agents). I grant that the broad approach is correct but argue that the temporal standpoint from which we judge whether the person can be held responsible, or the extent to which they can be held responsible, should be radically altered. Instead of asking, as Standard (or Static) Luck Egalitarianism seems to, whether or not, or to what extent, a person was responsible for the choice at the time of choosing, and asking the question of responsibility only once, we should ask whether, or to what extent, they are responsible for the choice at the point at which we are seeking to discover whether, or to what extent, the inequality is just, and so the question of responsibility is not settled but constantly under review. Such an approach will differ from Standard Luck Egalitarianism only if responsibility for a choice is not set in stone—if responsibility can weaken then we should not see the boundary between luck and responsibility within a particular action as static. Drawing on Derek Parfit’s illuminating discussions of personal identity, and contemporary literature on moral responsibility, I suggest there are good reasons to think that responsibility can weaken—that we are not necessarily fully responsible for a choice for ever, even if we were fully responsible at the time of choosing. I call the variant of luck egalitarianism that recognises this shift in temporal standpoint and that responsibility can weaken Dynamic Luck Egalitarianism (DLE). In conclusion I offer a preliminary discussion of what kind of policies DLE would support. (shrink)

The principle of homophily says that people associate with other groups of people who are mostly like themselves. Many online communities are structured around groups of socially similar individuals. On Twitter, however, people are exposed to multiple, diverse points of view through the public timeline. The authors captured 30,000 tweets about the shooting of George Tiller, a late-term abortion doctor, and the subsequent conversations among pro-life and pro-choice advocates. They found that replies between like-minded individuals strengthen group identity, whereas (...) replies between different-minded individuals reinforce in-group and out-group affiliation. Their results show that people are exposed to broader viewpoints than they were before but are limited in their ability to engage in meaningful discussion. They conclude with implications for different kinds of social participation on Twitter more generally. (shrink)

Using the methodology and findings of conversation analysis, we analyze changes in the talk of a man with aphasia (a language disorder acquired following brain damage) at two points in his spontaneous recovery period in the first months post-stroke. We note that in the earlier conversation (15 weeks post-stroke) two of the turn constructional methods he particularly makes use of are replacement (a form of repair) and extension. By the time of the latter conversation (30 weeks poststroke) these methods (...) are less prevalent, while another repair operation, insertion, is now used in a particular way not seen in the earlier conversation. We suggest that these methods are means by which the aphasic speaker adapts his limited linguistic resources to the demands of constructing a turn-at-talk in conversation in order to lessen the extent of repair and delay with the turn and thus lessen the exposure of his linguistic noncompetence and his identity as ‘different’, ‘disabled’, or ‘language impaired’. These turn constructional methods are dynamic and change as the speaker recovers. We suggest that communication disorders such as aphasia can be problematic not only because of difficulties they can cause in conveying information or producing other social actions, but also because they can create difficulties in the presentation of self in everyday life.

In lieu of an abstract, here is a brief excerpt of the content:Inheriting Identity and Practicing TransformationThe Time of Feminist PoliticsShannon HoffA human life unfolds over time. No moment of it can be considered apart from the others, independently of the fact that the human being was and will be, and so no moment is sufficient on its own to tell us of the nature of that identity. Each moment is insufficient as an expression of (...) who we are, as an answer to the question of what we want to be, or as a point at which a full account of our identity could be given. And we live each moment as if afflicted by a dual blindness with regard to the past and future that lend it significance; while exercising pervasive influence in the present, this past and future are relatively inaccessible to our reflective insight. We are always “growing up,” so to speak, from out of a childhood that can never be the purely transparent object of reflection, to an adulthood or “accomplishment” of identity that is always in the mysterious future, unimaginable in the terms of the adolescence in which we find ourselves.My purpose here is to show how this issue resonates in the context of feminist philosophy, feminist critique, and feminist practice—that is, how a consideration of time and its impact on human experience allows us to highlight the accomplishments of various avenues of feminist thought, to elaborate their shortcomings in relation to each other, to perceive the reasons behind the tensions among them, and to understand the way in which they are (and should [End Page 167] be understood as) connected. I will work through the issue of what it means to live in the temporal dimensions of past, present, and future—what it means to inherit an already meaningful world, to be an individual in the present, and to be propelled into an uncertain future—so as to provide a general framework by which to interpret the history of feminist thought. I will explain these different temporal dimensions in terms of the (respective) ideas of cultivation, universality, and transformation, identifying the positive and negative significance of each and also the demand that the tensions among them be negotiated. Finally, I will show that feminist justice is in fact found here, as answerability to all three—to communities of cultivation, to the demands of universality, and to the inconclusiveness and transformability of human identity. While much feminist thinking has been committed to exploring these elements singly, in abstraction from the others, and while such work is important, it is also valuable to explicitly explore the relationships and tensions among these different aspects, to articulate how to act and think in light of this underlying conceptual context, and to do so in a more explicit and self-conscious way.There is, of course, a disadvantage to not exploring these elements on their own terms: namely, that one handles their subtleties roughly. A further and related danger is that involved in trying to draw a broad picture of a tradition with complex and conflicting elements, one that does not count itself as a tradition at times—as a “we,” a feminism, or a feminist thought.1 While I will talk about “feminism” or “feminist thought,” I do not presume that these differences do not exist; my goal is simply to explore what is involved in an elaboration of a critical interpretation of society, when the society one critically interprets is an agent in one’s formation. The description of the dynamics of human becoming, agency, and critique I develop below has the purpose of showing that it is possible to understand differences between feminist positions as complementary, a process that will lead me to underemphasize stringent divisions and charged oppositions and to focus on drawing connections. Let us turn now to a preliminary description of the conceptual framework I seek to construct.Feminism and TimeTo advance feminist purposes is, one might presume, to hope for and work toward a new and transformed reality in the future. It would seem, however, that this reality cannot be clearly envisioned in the present, since that would require the transformation of the very people envisioning it. In... (shrink)

Among theories of personal identity over time the simple view has not been popular among philosophers, but it nevertheless remains the default view among non philosophers. It may be construed either as the view that nothing grounds a claim of personal identity over time, or that something quite simple (a soul perhaps) is the ground. If the former construal is accepted, a conspicuous difficulty is that the condition of causal dependence between person-stages is absent. (...) But this leaves such a view open to an objection from the failure to provide a condition of individuation. If, on the other hand something like a soul is said to ground personal identity over time, such an account turns out to be more suited to a kind of continuity view. (shrink)
