Weston La Barre on Human Nature

"“God” is often clinically paranoiac because the shaman’s “supernatural helper” is the projection of the shaman himself. The personality of Yahweh, so to speak, exactly fits the irascible personality of the sheikh-shaman Moses; the voices of Yahweh and Moses are indistinguishable. Of course, shamans do not always have an easy time of it. If the dereistic dreamer arouses too much anxiety, people call him crazy, just as people must put themselves at a psychological distance from the frightening and uncanny schizophrenic. But if the dreamer largely allays anxiety in the society, then he is the shaman-savior. Thus it is that outsiders to the society cannot tell the difference between a psychotic and a vatic personality. Only the society itself can distinguish between its psychotics and its shaman-saviors."
