Fantasy is not antirational, but pararational; not realistic but surrealistic, a heightening of reality. In Freud's terminology, it employs primary not secondary process thinking. It employs archetypes which, as Jung warned us, are dangerous things. Fantasy is nearer to poetry, to mysticism, and to insanity than naturalistic fiction is. It is a wilderness, and those who go there should not feel too safe.
Ursula K. Le GuinTrue myths may serve for thousands of years as an inexhaustible source of intellectual speculation, religious joy, ethical inquiry, and artistic renewal. The real mystery is not destroyed by reason. The fake one is. You look at it and it vanishes. You look at the Blonde Hero-really look-and he turns into a gerbil. But you look at Apollo, and he looks back at you. The poet Rilke looked at a statue of Apollo about fifty years ago, and Apollo spoke to him. "You must change your life," he said. When the true myth rises into consciousness, that is always its message. You must change your life.
Ursula K. Le GuinThe place they go towards is a place even less imaginable to us than the city of happiness. I cannot describe it at all. It is possible it does not exist. But they seem to know where they are going, the ones who walk away from Omelas.
