The Freud-Fliess letters reveal the immense difficulty with which Freud negotiated his revolution from without to within; they document the resistance that accompanied each of his steps away from the familiar terrain of so-called objective reality to the uncharted wilderness of psychic reality. This resistance was never completely overcome by Freud—as it is never overcome by anyone...The unexamined life may not be worth living, but the examined life is impossible to live for more than a few moments at a time. To fully accept the idea of unconscious motivation is to cease to be human. (p29)
