A comprehensive introduction to the nature of the self and its relation to the body, this title places the problem of personal identity in the context of more general puzzles about identity, and discusses the major related theories.

This volume collects a number of Perry’s classic works on personal identity as well as four new pieces, The Two Faces of Identity,Persons and Information,Self-Notions and The Self, and The Sense of Identity. Perry’s Introduction puts his own work and that of others on the issues of identity and personal identity in the context of philosophical studies of mind and language over the past thirty years.

This book challenges, with several powerful arguments, some of our deepest beliefs about rationality, morality, and personal identity. The author claims that we have a false view of our own nature; that it is often rational to act against our own best interests; that most of us have moral views that are directly self-defeating; and that, when we consider future generations the conclusions will often be disturbing. He concludes that moral non-religious moral philosophy is a young subject, with a promising but unpredictable future.

The relationship between personal identity and ethics remains on of the most intriguing yet vexing issues in philosophy. It is commonplace to hold that moral responsibility for past actions requires that the responsible agent is in some respect identical to the agent who performed the action. Is this true? On the other hand, can ethics constrain our account of personal identity? Do the practical requirements of moral theory commit us to the view that persons do remain identical over time? For example, does the moral status of abortion or stem cell research depend on whether personal identity is based on psychological or biological properties? Or is it the case that personal identity is not, in fact, relevant to ethics? Personal Identity and Ethics provides the first comprehensive examination of these issues. Topics include personal identity and prudential rationality; personal identity’s significance for moral responsibility and ethical theory; and the practical consequences of accounts of personal identity for issues such as abortion, stem cell research, cloning, advance directives, population ethics, multiple personality disorder, and the definition of death.

John Locke's theory of personal identity underlies all modern discussion of the nature of persons and selves—yet it is widely thought to be wrong. In this book, Galen Strawson argues that in fact it is Locke’s critics who are wrong, and that the famous objections to his theory are invalid. Indeed, far from refuting Locke, they illustrate his fundamental point. Strawson argues that the root error is to take Locke’s use of the word "person" as merely a term for a standard persisting thing, like "human being." In actuality, Locke uses "person" primarily as a forensic or legal term geared specifically to questions about praise and blame, punishment and reward. This point is familiar to some philosophers, but its full consequences have not been worked out, partly because of a further error about what Locke means by the word "conscious." When Locke claims that your personal identity is a matter of the actions that you are conscious of, he means the actions that you experience as your own in some fundamental and immediate manner. Clearly and vigorously argued, this is an important contribution both to the history of philosophy and to the contemporary philosophy of personal identity.

In this volume, Geoffrey Madell develops a revised account of the self, making a compelling case for why the "simple" or "anti-criterial" view of personal identity warrants a robust defense. Madell critiques recent discussions of the self for focusing on features which are common to all selves, and which therefore fail to capture the uniqueness of each self. In establishing his own view of personal identity, Madell proposes (a) that there is always a gap between ‘A is f and g’ and ‘I am f and g’; (b), that a complete description of the world offered without recourse to indexicals will fail to account for the contingent truth that I am one of the persons described; and (c), that an account of conscious perspectives on the world must take into account what it means for an apparently arbitrary one of these perspectives to be mine. Engaging with contemporary positions on the first person, embodiment, psychological continuity, and other ongoing arguments, Madell contends that there can be no such thing as a criterion of personal identity through time, that no bodily or psychological continuity approach to the issue can succeed, and that personal identity through time must be absolute, not a matter of degree. Madell’s view that the nature of the self is substantively different from that of objects in the world will generate significant discussion and debate among philosophers of mind.

As witnessed by recent films such as Fight Club and Identity, our culture is obsessed with multiple personality—a phenomenon raising intriguing questions about personal identity. This study offers both a full-fledged philosophical theory of personal identity and a systematic account of multiple personality. Gunnarsson combines the methods of analytic philosophy with close hermeneutic and phenomenological readings of cases from different fields, focusing on psychiatric and psychological treatises, self-help books, biographies, and fiction. He develops an original account of personal identity (the authorial correlate theory) and offers a provocative interpretation of multiple personality: in brief, "multiples" are right about the metaphysics but wrong about the facts.
