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.

Do people with multiple personalities have more than one self? The first full-length philosophical study of multiple personality disorder, First Person Plural maintains that even the deeply divided multiple personality contains an underlying psychological unity. Braude updates his work in this revised edition to discuss recent empirical and conceptual developments, including the charge that clinicians induce false memories in their patients, and the professional redefinition of "multiple personality disorder" as "dissociative identity disorder."

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.
