Given reductionism about people, personal persistence must fundamentally consist in some kind of impersonal continuity relation. Typically, these continuity relations can hold from one to many. And, if they can, the analysis of personal persistence must include a non-branching clause to avoid non-transitive identities or multiple occupancy. It is far from obvious, however, what form this clause should take. This paper argues that previous accounts are inadequate and develops a new proposal.

§I. Anti-realism of the sort which Michael Dummett has expounded takes issue with the traditional idea that an understanding of any statement (here, declarative sentence) is philosophically correctly analysed as involving grasp of conditions necessary and sufficient for its truth. Many kinds of statement to which, as we ordinarily think, we attach a clear sense would have to be represented, according to this tradition, as possessingverification-transcendenttruth-conditions; if true that is to say, they would be so in virtue of circumstances of (...) a type transcending our range of possible awareness. Exactly where to draw the boundaries of our possible awareness might be controversial; but there is clearly no being aware, in the relevant sense, of the kind of state of affairs which would make true a generalization of theoretical physics, an assertion about James II weight on his twenty-eighth birthday, a claim about what would have happened if Edward Heath had not sought a fresh mandate during the miners' strike, or—from your point of view—the statement that my left ear aches. In each of these kinds of case the traditional view, while granting that we (or you) cannot experience the truth-conferring states of affairs as such, would nevertheless credit us with a clear conception of the type of thing they would be. To be sure, there is then no possibility of a straightforward construal of this conception as a recognitional capacity. But the traditional view tends to conceal from itself the problematic status which the alleged grasp of truth-conditions therefore assumes by working with the picture that the ‘conception’ isindirectlyrecognitional, that itissues ina cluster of unproblematic recognitional capacities; in particular, the ability to recognize what is or is not good evidence for the relevant statement and the ability to recognize its logical relations to other statements.

Two closely related issues are addressed in this thesis. The first of these issues is whether Lockean criteria can withstand criticisms based on cases such as Wiggins' brain bisection case. The problem here is that the memory relation, or in general any relation of psychological continuity, seems to be a many-one relation and hence not suitable as a criterion of identity for persons. The second issue involves the question of what we ought to say about such cases. The problem here (...) is that, intuitively, psychological continuity seems to be a very good criterion of personal identity. When one person is psychologically continuous with a future person, we want to say that the one person has survived--as that future person. ;Several contemporary philosophers have addressed themselves to these issues. In Chapter I of the thesis, I consider the theory of identity suggested by Baruch Brody. He rejects Lockean criteria, and instead uses his own perfectly general theory as a criterion of identity. I argue that the theory he suggests is of limited value, and that the arguments he provides against Lockean criteria are question-begging. In Chapter II, I develop a specific Lockean criterion; in Chapter III, I consider and finally reject particular arguments against this criterion which are based on the brain bisection cases. In this chapter, I consider work by David Wiggins, Bernard Williams, and Roland Puccetti. In Chapter IV, I turn to the defense of Lockean criteria suggested by John Perry and David Lewis. Finally, in Chapter V, I develop my own views on the brain bisection case, and concluding that Lockean criteria of a certain sort remain defensible. (shrink)

Abstract: Those who endorse the Psychological Continuity Approach (PCA) to analyzing personal identity need to impose a non-branching constraint to get the intuitively correct result that in the case of fission, one person becomes two. With the help of Brueckner's (2005) discussion, it is shown here that the sort of non-branching clause that allows proponents of PCA to provide sufficient conditions for being the same person actually runs contrary to the very spirit of their theory. The problem is first presented (...) in connection with perdurantist versions of PCA. The difficulty is then shown to apply to endurantist versions as well. -/- . (shrink)

In this paper I discuss the nature of the “I” (or “self”) and whether it is presupposed by the very existence of conscious experiences (as that which “has” them) or whether it is, instead, in some way constituted by them. I argue for the former view and try to show that the very nature of experience implies a non-constituted synchronic and diachronic transcendence of the experiencing “I” with regard to its experiences, an “I” which defies any objective characterization. Finally I (...) suggest that the self, though irreducible to inter-experiential relations, is not a “separately existing entity”, but should be conceived of as a dimension , namely the dimension of first-personal manifestation of the experiences.

In this article, I develop and defend a conception of psychological continuity that differs from the 'orthodox' conception in terms of overlapping chains of strongly connected mental states. By recognizing the importance of the (narrative) interrelatedness of qualitatively dissimilar mental contents, as well as the role of the body in psychological continuity, I argue, serious problems confronting the orthodox view can be solved.

In this volume, thirteen philosophers contribute new essays analyzing the criteria for personal identity and their import on ethics and the theory of action: it presents contemporary treatments of the issues discussed in Personal Identity, edited by John Perry (University of California Press, 1975).

The animalist says we are animals. This thesis is commonly understood as the universal generalization that all human persons are human animals. This article proposes an alternative: the thesis is a generic that admits of exceptions. We defend the resulting view, which we call ‘generic animalism’, and show its aptitude for diagnosing the limits of eight case-based objections to animalism.

To the extent that the performance of embodied and situated cognitive agents is predicated on fore- thought;such agents must remember; and learn from; the past to predict the future. In complex; non-stationaryenvironments; such learning is facilitated by an intrinsic motivation to seek novelty. A significant part of anagent’s identity is thus constituted by its remembered distilled cumulative life experience; which the agent isdriven to constantly expand. The combination of the drive to novelty with practical limits on memorycapacity posits a problem. (...) On the one hand; because novelty seekers are unhappy when bored; merelyreliving past positive experiences soon loses its appeal: happiness can only be attained sporadically; via anopen-ended pursuit of new experience. On the other hand; because the experiencer’s memory is finite;longevity and continued novelty; taken together; imply eventual loss of at least some of the stored content;and with it a disruption of the constructed identity. In this essay; I examine the biobehavioral and cognitive-computational circumstances that give rise to this problem and explore its implications for the humancondition. (shrink)

Animalism is at once a bold metaphysical theory and a pedestrian biological observation. For according to animalists, human persons are organisms; we are members of a certain biological species. In this article, I introduce some heretofore unnoticed data concerning the interlocking interests of human persons and human organisms. I then show that the data support animalism. The result is a novel and powerful argument for animalism. Bold or pedestrian, animalism is true.

Many bioethical arguments rely implicitly on the assumption that the concept of “human part” is one on which everyone must agree, because it is unambiguous. But various parties interpret this “unambiguous” term in incompatible ways, leading to contention. This article is an informal presentation of a topomereological system on whose preferred interpretation several distinct but related meanings of “human part” can be isolated: part of a human body, part of the completion of a human body, and part of a human (...) being. A case is analyzed (the first total artificial heart (TAH) implantation), demonstrating in the process much of the apparatus of the system. By means of a casuistic methodology, the analysis is translated into recommendations for the ethical conduct of future TAH research. The more general conclusion, however, is that formal methods may provide useful tools for clarifying thought processes and organizing arguments in debates over bioethical issues. (shrink)

Stanley Klein and Shaun Nichols describe the case of patient R.B., whose memories lacked the sense of “mineness” usually conveyed by memory. Klein and Nichols take R.B.’s case to show that the sense of mineness is merely a contingent feature of memory, which they see as raising two problems for memory-based accounts of personal identity. First, they see it as potentially undermining the appeal of memory-based accounts. Second, they take it to show that the conception of quasi-memory that underpins many (...) memory-based accounts is inadequate. I argue that Klein and Nichols’ characterization of R.B.’s experience is implausible; as a result, the problems that they describe for memory-based accounts of personal identity do not arise.

The purpose of this thesis is to provide a brief examination of the historical accounts of philosophical theories of personal identity and show the influence that each has had on the development of contemporary theories. In doing so, the thesis explores the problems associated with these theories, attempting to establish a meta-theory of personal identity. What is demonstrated is that the fundamental problems of personal identity arise from issues related to the use of language, as well as assumptions involving the (...) concept of personhood. By demonstrating that our understanding of personhood is relative to frameworks of understanding based on assumption, the meta-theory states that propositions made about persons are not factual statements, but are, rather, matters of contingency. As such, propositions about persons contain truth-value only within a particular frame of reference that is based on these assumptions. Therefore, the problems that traditionally arise in theories of personal identity -- problems with dualism, the mental criterion, and bodily criterion -- result from a flawed approach to the problem altogether. The conclusion is that it is possible to construct a theory of personal identity, but not the theory of personal identity. (shrink)

This seminal contribution to Kant studies, originally published in 1982, was the first to present a thorough survey and evaluation of Kant's theory of mind. Ameriks focuses on Kant's discussion of the Paralogisms in the Critique of Pure Reason, and examines how the themes raised there are treated in the rest of Kant's writings. Ameriks demonstrates that Kant developed a theory of mind that is much more rationalistic and defensible than most interpreters have allowed.

It is often argued that associations are intelligent organisms with minds and intentional states of their own. It is also argued that groups are merely a plurality of individuals who are related or associated only in a specific and limited sense. This paper draws on both classical and contemporary scholarship to develop an ontological account of persons which has real-world legal and ethical implications.

On many accounts, the criterion of our diachronic identity or persistence consists in or comprises some psychological conditions. As on Locke's account, these conditions often include one's appealing to the relation of remembering having an experience of. Contemporary theorists are unlikely to claim simply that a necessary condition for Pm at tm being the same person as Pn at a later time, tn, is that Pn remembers having experiences had by Pm at tm. They are more likely to appeal, as (...) does Derek Parfit, to a ‘continuity of memory’ or ‘overlapping chains’ of memories, that is, to assert that Pn must at least remember having experiences had by somebody, Pn-1, existing at some time in-between tm and tn, that Pn-1 in turn must remember having experiences had by somebody Pn-2 … and so on back to Pm.
