The strength of the computer lies in its being a logic machine. It does precisely what it is programed to do. This makes it fast and precise. It also makes it a total moron; for logic is essentially stupid. It is doing the simple and the obvious. The human being, by contrast, is not logical; he is perceptual. This means that he is slow and sloppy. But he is also bright and has insight. The human being can adapt; that is, he can infer from scant information or from no information at all what the total picture might be like. He can remember a great many things nobody has programed.
