Copyright 1981. This has always been one of my favorite books, but it's illuminating to read it again with new eyes. Some of the messages there. Learned them at 10 as fiction. Learning them again at 45 as more than fiction.
(Possible spoilers in the quotes.)
The gnomes message in the rock world about all life being one.
"Others having forgotten that all life is one, and meaning harm to dance-world, tree-world, light-world. So making them, in pain, one with self-substance, showing them once that all life is one."
Cam's learning to let go and trust his instincts.
He did not know if he was reading the old man's thoughts, or whether it was intuition or clairvoyance. Maybe, in the universe he was now inhabiting, there was no difference between them. He simply knew. Jennifer had somehow known that he was ready for that knowledge. Cameron Fenton had been a parapsychologist for ten years. And he knew, now, that he was only beginning to learn the very first thing about parapsychology. It was an opening door, a new world he was entering, a new universe.
The dig at organized religion.
How long had the Worldhouse been in operation? Probably, he thought, from time immemorial—if time had any meaning in the new picture of the cosmos which the very existence of the Worldhouse had given him. And somewhere along that line, control of the Gates had slipped. In Pentarn's world they had fallen under control of a power-mad dictator who was using them recklessly for his own purposes, without realizing what this might do to the Gates. And in Fenton's world, their existence had been forgotten, kept secret, eventually fallen into the hands of amateurs and volunteers because the scientific establishment was less and less ready to accept anything like that. The time could be measured in millennia here, too. Certainly the Worldgates had not been known in historical times. But historical time, according to some new theories, was only a fraction of the time man had lived on this planet... unless you wanted to stick to the exploded theory that history had begun in 4004 BC when God created the world in seven days, fossils and all, to confuse the ungodly.
The observation that parapsychology is one of the few fields where no amount of evidence will change people's minds.
What would it matter, then, if we did prove that some people can hear things believed to be out of earshot and see things out of the range of their eyes? Most of us have known all along that clairvoyance and clairaudience are facts; why should we spend all this effort trying to prove these things to ignoramuses who have told us they wouldn't believe them with ten times the evidence, anyhow?
And having gone that far Fenton was forced to stop and wonder: what was a fact anyhow?
The idea of risks and path and purpose.
"All the same," Fenton said, "I have the right to choose what risks I will take." He had been taking risks, knowingly, ever since he chose parapsychology as a field—first, the risk of abandoning a respectable psychologist's profession, then the risks of strange talents, experimentation with drugs that could loosen the inner girders of the mind. He wondered if all those risks had been run to prepare him for this moment of choice.
The total sceptic and the true believer.
Sally laughed and nodded. "I forget which scientist it was who said that the universe is not only queerer than we imagine, but queerer than we can imagine," she said.
"That's so," Uncle Stan agreed. "In your business—Cam told me you were working in parapsychology too—you ought to know that, if anybody does. You must get awfully tired of skeptics who don't believe what's right under their noses. And almost as tired, I'd imagine, of people who believe all kinds of hogwash without a shred of proof. You folks really have to walk a chalk line, in that business, don't you? Skepticism on one side and credulity on the other, and both of them completely blind to logic and rational proof, either way."
"Oh, you're so right," Sally said. "That's why we try to make sure the people we take in the department are fairly stable to start with. Accept an ignorant and logic-proof skeptic, breach his skepticism, and he turns into an equally ignorant and logic-proof True Believer."
And this....
He just didn't like the idea of being a Flat-Earther of the mind, the kind of person who didn't want facts muddling up his prejudices.
