“[Aldous Huxley] compared the brain to a 'reducing valve'. In ordinary perception, the senses send an overwhelming flood of information to the brain, which the brain then filters down to a trickle it can manage for the purpose of survival in a highly competitive world. Man has become so rational, so utilitarian, that the trickle becomes most pale and thin. It is efficient, for mere survival, but it screens out the most wondrous part of man's potential experience without his even knowing it. We're shut off from our own world.”

“... 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.”

“Prediction in a complex world is a chancy business. Every decision that a survival machine takes is a gamble, and it is the business of genes to program brains in advance so that on average they take decisions that pay off. The currency used in the casino of evolution is survival, strictly gene survival, but for many purposes individual survival is a reasonable approximation.”

“When anxiety becomes problematic, most people try vainly to think their way out of trouble. But worry has its roots in the reptilian brain, minimally responsive to will. As a wise psychoanalyst once remarked of the autonomic nervous system (which carries the outgoing fear messages from the reptilian brain), "It's so far from the head it doesn't even know there is a head." (49)”

“Your brain can only process a tiny portion of your environment,It risks being overwhelmed by the volumeof information that bombards you every waking moment.Your brain compensates by filtering out the 99.9 percent ofyour environment that doesn’t matter to you.”

“There is more information in one thimble of realitythan can be understood by a galaxy of human brains. It isbeyond the human brain to understand the world and itsenvironment, so the brain compensates by creating simplifiedillusions that act as a replacement for understanding.”
