“In his blackest hours, Stone doubted the utility of all thought, and all intelligence. There were times he envied the laboratory rats he worked with; their brains were so simple. Certainly, they did not have the intelligence to destroy themselves; that was a peculiar invention of man.”

“There were times when [he] allowed himself to see clearly that he would end his working life, that was to say, his conscious thinking life, in this task, that all his thoughts would have been another man's thoughts, all his work another man's work. And then he thought it did not perhaps matter so greatly... It was a pleasant subordination, if he was a subordinate.”

“For instance, on the planet Earth, man had always assumed that he was more intelligent than dolphins because he had achieved so much—the wheel, New York, wars and so on—whilst all the dolphins had ever done was muck about in the water having a good time. But conversely, the dolphins had always believed that they were far more intelligent than man—for precisely the same reasons.”

“Man is so intelligent that he feels impelled to invent theories to account for what happens in the world. Unfortunately, he is not quite intelligent enough, in most cases, to find correct explanations. So that when he acts on his theories, he behaves very often like a lunatic.”

“So said Hair-Face, and they killed him, because, they said, he was a wild man and wanted to go back and live in a tree. It was very strange. Whenever a man arose and wanted to go forward all those that stood still said he went backward and should be killed. And the poor people helped stone him, and were fools. We were all fools, except those who were fat and did no work. The fools were called wise, and the wise were stoned. Men who worked did not get enough to eat, and the men who did not work ate too much.”

“If God did not exist, He would have to be invented. But all nature cries aloud that he does exist: that there is a supreme intelligence, an immense power, an admirable order, and everything teaches us our own dependence on it.”
