Alchemy and Kabbalah are later developments in my thinking. I think the primary interest has been the relationship of magic and mystery to logic and understanding.

It's very frustrating if you've never had an experience and somebody comes up to you and says, "I've just been on a flying saucer." Your tendency is to think, "Oh, this guy must be wacko, nuts, having an hallucination. None of that can be true because none of that has ever happened to me."
