This book brings together some of the best minds in neurology and philosophy to discuss the concept of personal identity and the moral dimensions of treating ...

Addressing many topics in epistemology and metaphysics, this treatise sets out a new theory of the unity of objects, and discusses personal identity, the metaphysics of possible worlds, the continuity in space time, and the nature of philosophical theorizing.

In this essay I take issue with Derek Parfit's reductionist account of personal identity.Parfit is concerned to respond to what he sees as flaws in the conception of the role of 'person' in self-interest theories. He attempts to show that the notion of a person as something over and above a totality of mental and physical states and events (in his words, a 'further fact'), is empty, and so, our ethical concerns must be based on something other than this. My objections centre around the claim that Parfit employs an impoverished conception of 'life'. Parfit misconceives the connection between 'I' and one's body, and, so, despite his rejection of a metaphysical conception of 'self', remains within the logic of Cartesianism. What Parfit and other reductionists call an 'impersonal' perspective, I shall call the third-person perspective: a perspective which one in general may take. Against Parfit I shall offer a more complex conception of 'self' through the concept of 'bodily perspective'. I emphasize the irreducible ambiguities of human embodiment in order to show the presuppositions and the limitations of Parfit's view. Of interest is the conception of time and the model of continuity that is appropriate to an embodied subject's life. I employ Paul Ricoeur's concept of 'human time' to argue that the reflective character of human experience demands a model of temporality and continuity that differs significantly from the one Parfit employs.

This thesis gives an overview of the topic of personal identity from a philosophical viewpoint, describing both numerical and qualitative aspects. Reductionist approaches to numerical identity, such as the neo-Lockean psychological continuity theory of Derek Parfit or the physical criterion theory of Bernard Williams, are subject to a discussion. Apart from some significant criticisms in detail, there is the more general problem that they appear to imply a kind of neo-dualism. As a consequence, the author suggests a holistic approach to numerical personal identity which is more in accord with our times, placing the body firmly at the center of focus. The section on qualitative identity aims to develop a more complex theory of psychological continuity and continuity per se than that generally found in the literature. The suggestion is made that the most viable way to bring together the various strands of personal identity, both numerical and qualitative, is a concept of narrativity. Narratives are both indicative of and constitutive of personal identity.

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.

This lucid book is the first to be wholly dedicated to Hume's theory of personal identity, and presents a bold new interpretation which bears directly on ...

The first book synthesizing the many different topics that surround the issue of personal identity, this text makes an important contribution to the philosophy of personal identity and mind, and to epistemology.

The Euro-American philosophical traditions offer two extreme positions to the problem of identity over time: G. W. Leibniz' essentialism and Derek Parfit's reductionism. A third alternative conception of personal identity is presented here, more appropriately named personal nonduality, which is based on Nishida Kitarō's conception of personal unity as nonrelative contradictory self-identity.

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