Many of us experience ourselves as having or being a 'self', even though we may not be clear what that is. The philosophical papers in this volume reflect on key questions about the self, such as: Does the self exist? If so, what is its nature? Is it a single thing, or could there be a succession of selves? Could our sense of a single continuous self be an illusion? What are the ethical implications of selfhood? And what is the relation between self-expression and self-control? The papers are written by leading authorities in the field: Barry Dainton, Ingmar Persson, Marya Schechtman, Bas van Fraassen, Peter van Inwagen, and the volume editor, Galen Strawson.
