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

In recent years largely due to the seminal work of Kit Fine and that of Jonathan Lowe there has been a resurgence of interest in the concept of essence and the project of explaining de re necessity in terms of it. Of course, Quine rejected what he called Aristotelian essentialism in his battle against quantified modal logic. But what he and Kripke debated was a notion of essence defined in terms of de re necessity. The new Aristotelian essentialists regard essence (...) as entailing but prior in the order of explanation to de re necessity. In what follows I argue that the concept of essence so understood has not been adequately explained and that any attempt to explain it, at least along the lines most familiar from the literature, must be flagrantly circular or make use of de re modal notions.

Examples suggest that one and the same A may be different Bs, and hence that there is some sort of incompleteness in the unqualified statement that x and y are the same which needs to be eliminated by answering the question “the same what?” One way to make this more precise is by appeal to Geach's idea that identity is relative. In this paper I evaluate Geach's relative identity thesis.

My purpose is to explore the possible lines of reply available to a defender of the neo‐Lockean position on personal identity in response to the recently popular ‘animalist’ objection. I compare the animalist objection with an objection made to Locke by Bishop Butler, Thomas Reid and, in our own day, Sydney Shoemaker. I argue that the only possible response available to a defender of Locke against the Butler–Reid–Shoemaker objection is to reject Locke's official definition of a person as a thinking, (...) intelligent thing and replace it with the concept of the self– the object of self‐reference – and that this response is equally obligatory for the neo‐Lockean in replying to the animalist. I explore other possibilities, including the position that there is no sense in talking about personal identity at all. (shrink)

The essays in this volume apply philosophical analysis to address three kinds of questions: What are the implications of genetic science for our understanding of nature? What might it influence in our conception of human nature? What challenges does genetic science pose for specific issues of private conduct or public policy?

In this book, Eli Hirsch focuses on identity through time, first with respect to ordinary bodies, then underlying matter, and eventually persons. These are linked at various points with other aspects of identity, such as the spatial unity of things, the unity of kinds, and the unity of groups. He investigates how our identity concept ordinarily operates in these respects. He also asks why this concept is so cental to our thinking and whether we can justify seeing the world in (...) terms of such a concept. This is the revised and updated edition of a hardback published in 1982. (shrink)

How is the debate between presentism and eternalism to be characterized? It is usual to suggest that this debate about time is analogous to the debate between the actualist and the possibilist about modality. I think that this suggestion is right. In what follows I pursue the analogy more strictly than is usual and offer a characterization of what is at the core of the dispute between presentists and eternalists that may be immune to worries often raised about the substantiality (...) of the debate. I suggest that the debate be characterized in Lewisean terms and define positions I call *Lewisean* eternalism and anti-*Lewisean*' presentism (analogous to Lewisean possibilism and anti-Lewisean actualism). I explain some advantages of the proposal and discuss some objections. I conclude that pursuing the analogy strictly offers the prospect of giving clear sense to a controversy which otherwise seems to many deeply obscure. (shrink)

In the first twelve chapters of this book, I am concerned with the Fregean notion of an object (the reference of a proper name) and its connection with the notion of identity. The rest of the book is devoted to a discussion of the problem of personal identity.

As our scientific and technical abilities expand at breathtaking speeds, concern that modern genetics and bioengineering are leading us to a posthuman future is growing. Is Human Nature Obsolete? poses the overarching question of what it is to be human against the background of these current advances in biotechnology. Its perspective is philosophical and interdisciplinary rather than technical; the focus is on questions of fundamental ontological importance rather than the specifics of medical or scientific practice.The authors -- all distinguished scholars (...) in their fields -- take on questions about technology's goals and values that are often ignored or sidelined in the face of rapid scientific advances and the highly specialized nature of technical knowledge. The essays included represent a rich variety of thought, ranging from finely nuanced philosophical and theological arguments to historical studies and cultural commentaries. Several explore the historical background of today's biotechnology: Timothy Casey traces such developments as the emergence of cybernetic humanity from Cartesian dualism, and Diane Paul presents the history of "positive" versus coerced eugenics. Jean Bethke Elshtain discusses cloning as a "messianic project" to perfect the body and exclude natural diversity -- giving as an example the elimination of Down Syndrome as an acceptable human type -- while Harold Baillie calls for an examination of the metaphysical roots of personhood. Robert Proctor finds no evidence in paleontology for any "essence of humanity," and Tom Shannon argues against materialist reductionism. Addressing social concerns, Lisa Sowle Cahill finds the possibility of a political solution to the problems raised by genetic engineering in Catholic teachings on social justice, and Langdon Winner looks critically at the "scientific enthusiasts of a posthuman future." Taken as a whole, the book provides a humanistic overview of a subject too often considered only in its technological aspect. (shrink)

The aim of the paper is to discuss some recent variants of familiar puzzles concerning the relations of parts to wholes put forward by Trenton Merricks and Eric Olson. The argument is put forward that so long as the familiar distinction between 'loose and popular' and 'strict and philosophical' senses of identity claims is accepted the paradoxical conclusions at which Merricks and Olson arrive can be resisted. It is not denied that accepting the distinction between 'loose and popular' and 'strict (...) and philosophical' senses of identity claims is itself a departure from common-sense, but it is argued that it is the smallest such departure available to us.

The paper defends Gareth Evan's argument against vague identity "de re" from a criticism that quantum mechanics provides actual counter-examples to its validity. A more general version of Evans's argument is stated in which identity involving properties are not essential and it is claimed that the scientific facts as so far known are consistent with the Evansian thesis that indeterminacy in truth-value must always be due to semantic indecision.

To reduce the spread of the human immunodeficiency virus (HIV), Granich et al. 1 ( 2009 ) have proposed a new strategy for universal voluntary HIV testing immediately followed by antiretroviral therapy. Although this proposal is likely to benefit the partners of those affected and thus promote public health, it is by no means clear that it benefits the infected people themselves and indeed it may be harmful. Since the proposal involves an intervention that is not clinically indicated, it falls (...) foul of the normal ethical standards of clinical medicine, which is to act in the best interests of patients. Neither is it a measure that would be imposed under the protection of public health law on people who are seen as representing such danger to others that significant restrictions in liberty are appropriate. Thus, the proposal represents a third category of public health measure. We argue that a coherent ethical framework including a robust process is appropriate to proposals of this kind and that medical research offers a useful model since some research, like this proposal, is motivated not by the interests of the individual participants but by the common good. We outline some possible elements of such an ethical framework. (shrink)

There is a well-developed literature on trust. In his important article Faulkner, 424−429, 2015) distinguishes three-place, two-place and one-place trust predicates. He then argues that our more basic notions of trust are expressed by the one-place and two-place predicates. Three-place trust, contractual trust, is not fundamental. This matters. Having a clear understanding of our concepts of trust is important. The most important assumption of Faulkner’s argument is that the notion of trust expressed by the three-place predicate is not attitudinal; it (...) is a ‘metaphysical hybrid of attitude and action’. I argue that this is wrong. All three notions are attitudinal and no reason exists to deny that the one-place and two-place notions derive from the three-place one. Once one rejects Faulkner’s assumption that the three-place notion can be separated off from the others as a metaphysical hybrid argument for the priority of the one-place and two-place notions collapses.

Personal Identity is a comprehensive introduction to the nature of the self and its relation to the body. Harold Noonan places the problem of personal identity in the context of more general puzzles about identity, discussing the major historical theories and more recent debates. The second edition of Personal Identity contains a new chapter on 'animalism' and a new section on vagueness.

A plausible principle governing identity is that whether a later individual is identical with an earlier individual cannot ever merely depend on whether there are, at the later time, any better candidates for identity with the earlier individual around. This principle has been a bone of contention amongst philosophers interested in identity for many years. In his latest book Philosophical Explanations Robert Nozick presents what I believe to be the strongest case yet made out for the rejection of this principle. (...) My aim in this paper is to argue, with reference in particular to personal and artefact identity, that Nozick's case can be met and that a theory of identity which entails the correctness of this principle is the equal, indeed the superior, in explanatory power of the theory Nozick develops on the basis of its rejection.

Debate between Humean contingentists and anti-Humean necessitarians in the philosophy of science is ongoing. One of the most important contemporary anti-Humeans is Alexander Bird. Bird calls the particular version of Humeanism he is opposed to 'categoricalism'. In his paper (2005) and in Chapter 4 of his book (2007) Bird argues against categoricalism about properties and laws. His arguments against categoricalism about properties are intended to support the necessitarian position he calls dispositional monism. His arguments against categoricalism about laws are intended (...) to refute the contingent regularity view of laws (even in its sophisticated Lewisean version) and the nomic necessitation view of Armstrong (which involves a contingent necessitation relation). The general position Bird defends is that properties are necessarily related to the dispositions they bestow on their bearers and laws are necessary truths. I consider two of Bird's arguments against categoricalism about properties, and one of his arguments against the regularity view of laws. Maybe other arguments against categoricalism are persuasive. These, I submit, are not. (shrink)
