And if ever the suspicion of their manifold being dawns upon men of unusual powers and of unusually delicate perceptions, so that, as all geniuses must, they break through the illusion of the unity of the personality and perceive that the self is made up of a bundle of selves… A man, therefore, who gets so far as making the supposed unity of the self twofold is already almost a genius, in any case a most exceptional and interesting person. In reality, however, every ego, so far from being unity, is in the highest degree a manifold world, a constellated heaven, a chaos of forms, of stages and stages, of inheritances and potentialities. It appears to be a necessity as imperative as a eating or breathing for everyone to be forced to regard this chaos as a unity and to speak of his ego as though it were a onefold and clearly detached and fixed phenomenon. Even the best of us share the delusion.

Hermann Hesse, from Steppenwolf
