"Right. What would happen if the whole brain were used?
"Andy, what kind of a card file would you need to do the following: One: locate from a mention the complete account of a complex experience; two: do it almost instantly, and three: compile the data in five dimensions?"
"Five dim—? Are you kidding?"
"Not at all. Each of the five senses are essentially different and will require separate cards to make the picture complete. A rose smell, for instance, would be meaningless alone—you must classify it. The same card would not fit for all rose-smelling memories since some are strong, some are weak, some are mixed with other minor odors, and so forth. Do you follow?"
"Yes, but aren't we getting off the track?"
"Not at all. If your mind can run through ten to the fiftieth power experiences in five mediums and come up with the proper, correlated accounts, all in a matter of seconds—think what the same mind might be able to do if presented with a lesser problem."
"Why can't it do just that?"
"Because when you start to figure out a problem, something restricts your brain power to less than ten percent of its capability."
"That means that ninety percent of the brain is nonfunctional."
"Right. It is. You can carve better than half of a man's brain out and not impair a single memory, or action, or ability."
