“Already, the brain consumed more than a quarter of the body's blood supply... an organ accounting for only a small percentage of body mass. If brains grew larger, and better, then perhaps they would consume more - perhaps so much that, like an infection, they would overrun their hosts and kill the bodies that transported them. Or perhaps, in their infinite cleverness, they would find a way to destroy themselves and each other. There were times when, as he [Stone] sat at State Department or Defense Department meetings, and looked around the table, he would see nothing more than a dozen gray, convoluted brains sitting on the table... Just brains, sitting around, trying to decide how to outwit other brains, at other conference tables.Idiotic.”

“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.”

“... we have created a man with not one brain but two. ... This new brain is intended to control the biological brain. ... The patient's biological brain is the peripheral terminal -- the only peripheral terminal -- for the new computer. ... And therefore the patient's biological brain, indeed his whole body, has become a terminal for the new computer. We have created a man who is one single, large, complex computer terminal. The patient is a read-out device for the new computer, and is helpless to control the readout as a TV screen is helpless to control the information presented on it.”

“Paul Broca, for example, was a famous French craniologist in the nineteenth century whose name is given to Broca’s area, the part of the frontal lobe involved in the generation of speech (which is wiped out in many stroke victims). Among his other interests, Broca used to measure brains, and he was always rather perturbed by the fact that the German brains came out a hundred grams heavier than French brains. So he decided that other factors, such as overall body weight, should also be taken into account when measuring brain size: this explained the larger Germanic brains to his satisfaction. But for his prominent work on how men have larger brains than women, he didn’t make any such adjustments. Whether by accident or by design, it’s a kludge.”

“More of your conversation would infect my brain.”

“He sees a human body of a type that is supposed to fit the curves of his brain, but the body is so warped and broken that it can no longer cozy up to any of those curves.”

“The only shame George Webber felt was that at one time in his life, for however short a period, he broke bread and sat at the same table with any man when the living warmth of friendship was not there; or that he ever traded upon the toil of his brain and the blood of his heart to get the body of a scented whore that might have been better got in a brothel for some greasy coins. This was the only shame he felt. And this shame was so great in him that he wondered if all his life thereafter would be long enough to wash out of his brain and blood the last pollution of its loathsome taint.”
