"In the next few days you will master the rules and techniques for every activity, skill, talent, sport and art ever mastered by any human being anywhere. You will be as expert at clipping flints as at architectural drawing. You will be able to juggle, walk a tightrope and add the numerals on the sides of passing freight cars as fast as any idiot savant. You’ll absorb all the information in all the books — the human race’s entire heritage of knowledge…"This was only the beginning of the experiment that was to turn a petty thief into the mos brilliant and powerful man ever to hold the earth in thrall.This was only the first step on the path of conquest mapped out for — THE ULTIMAX MAN.
