“These rare mini mind-blanks always seemed to occur when he needed perking up, creative jolts as if his brain had temporarily overclocked its processor to light-speed frequency, but with the side effect of shutting his consciousness down to protect it from overheating. That theory certainly fit the observable phenomena. Then again, the competing theories included: he was nuts; he had a brain tumour; aliens had temporarily abducted him.”

“It is worth repeating at this point the theories that Ford had come up with, on his first encounter with human beings, to account for their peculiar habit of continually stating and restating the very very obvious, as in "It's a nice day," or "You're very tall," or "So this is it, we're going to die."His first theory was that if human beings didn't keep exercising their lips, their mouths probably shriveled up.After a few months of observation he had come up with a second theory, which was this--"If human beings don't keep exercising their lips, their brains start working.”

“If it wasn’t for the mist we could see your home across the bay," said Gatsby. "You always have a green light that burns at the end of your dock."Daisy put her arm through his abruptly but he seemed absorbed in what he had just said. Possibly it had occurred to him that the colossal significance of that light had now vanished forever. Compared to the great distance that had separated him from Daisy it had seemed very near to him, almost touching her. It had seemed as close as a star to the moon. Now it was again a green light on a dock. His count of enchanted things had diminished by one.”

“why had he happened to hear such a discussion and such ideas at the very moment when his own brain was just conceiving … the very same ideas? And why, just at the moment when he had brought away the embryo of his idea from the old woman had he dropped at once upon a conversation about her? This coincidence always seemed strange to him. This trivial talk in a tavern had an immense influence on him in his later action; as though there had really been in it something preordained, some guiding hint…”

“Moreover, during his wife's confinement, something had happened that seemed extraordinary to him. He, an unbeliever, had fallen into praying, and at the moment he prayed, he believed. But that moment had passed, and he could not make his state of mind at that moment fit into the rest of his life.”

“I don't think it had ever occurred to me that man's supremacy is not primarily due to his brain, as most of the books would have one think. It is due to the brain's capacity to make use of the information conveyed to it by a narrow band of visible light rays. His civilization, all that he had achieved or might achieve, hung upon his ability to perceive that range of vibrations from red to violet. Without that, he was lost.”
