That society is strong and viable which recognizes its own provisionality. In fact, I learned something just the other day. Talking about the Uroc Indians, an early explorer up there commented on their fantastic self-confidence. Every Indian has this fantastic self-confidence. Yes, every healthy culture does.
Every healthy culture provides for there being non-joiners.
A society like the Comanche or the Sioux demands that everybody go out there and have this vision, and incorporates and ritualizes it within the culture. Then a society like India, a step more civilized, permits some individuals to have these visions, but doesn't demand it of everyone. And then later it becomes purely eccentric. It may be explained by the theory of reincarnation. They're still entranced by all of the manmade props.
