"There has never been a book remotely like this one in its profusion of ancient references on ideas about human identity and selfhood . . . . Readers unfamiliar with the subject also need to know that Sorabji breaks new ground in giving special attention to philosophers such as Epictetus and other Stoics, Plotinus and later Neoplatonists, and the ancient commentators on Aristotle (on the last of whom he is the world's leading authority)."--Anthony A. Long, Times Literary Supplement
