Abstract
Ego psychology, more existential than scientific in tone, has made psychoanalytic theory more congenial to historical studies, especially when they deal with creative and conflicted leaders. Erikson's concept of the identity crisis points to the intersection of family-centered conflicts with social and cultural history. It also orients the historian to the reanimation of problems in earlier stages of the life-cycle, the importance of work to identity formation, and the neurotic function of over-identification with a troublesome parent. Phenomenologically descriptive rather than causally explanatory, psycho-biography mediates between Freud's naturalism and Collingwood's idealism by relating conscious and unconscious purposes. It establishes congruences and resonances, helping to explain in narrative form the meaning, timing, and urgency of a leader's characteristic ideas.
