Philosophy of Personal Identity and Multiple Personality

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.

Logi Gunnarsson is Professor of Philosophy at University of Potsdam, Germany.
