“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.”

“He who will not use the thoughts of other men's brains proves that he has no brains of his own.”

“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 entirely personal experience of them, English was jazz music, German was classical music, French was ecclesiastical music, and Spanish was from the streets. Which is to stay, stab his heart and it would bleed French, slice his brain open and its convolutions would be lined with English and German, and touch his hands and they would feel Spanish.”

“He unzipped his pants and his brains fell out.”
