“... 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.”

“Considering that we live in an era of evolutionary everything---evolutionary biology, evolutionary medicine, evolutionary ecology, evolutionary psychology, evolutionary economics, evolutionary computing---it was surprising how rarely people thought in evolutionary terms. It was a human blind spot. We look at the world around us as a snapshot when it was really a movie, constantly changing.”

“Our metaphors for the operation of the brain are frequently drawn from the production line. We think of the brain as a glorified sausage machine, taking in information from the senses, processing it and regurgitating it in a different form, as thoughts or actions. The digital computer reinforces this idea because it is quite explicitly a machine that does to information what a sausage machine does to pork. Indeed, the brain was the original inspiration and metaphor for the development of the digital computer, and early computers were often described as 'giant brains'. Unfortunately, neuroscientists have sometimes turned this analogy on its head, and based their models of brain function on the workings of the digital computer (for example by assuming that memory is separate and distinct from processing, as it is in a computer). This makes the whole metaphor dangerously self-reinforcing.”

“First, we cannot overload the human brain. This divinely created brain has fourteen billion cells. If used to the maximum, this human computer inside our heads could contain all the knowledge of humanity from the beginning of the world to the present and still have room left over. Second, not only can we not overload our brain - we also know that our brain retains everything. I often use saying that "The brain acquires everything that we encounter." The difficulty does not come with the input of information, but getting it out. Sometimes we "file" information randomly of little importance, and it confuses us.”

“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.”

“But it was one thing to release a population of virtual agents inside a computer's memory to solve a problem. It was another thing to set real agents free in the real world.”
