The numerologist said, “Then you want me to help you provided I don’t embarrass you by telling you the silly nonscientific basis of the way in which I helped you. Is that it?”

“All right. That’s it.”

“But you still work on the assumption that I am a numerologist, and I am not. I call myself that so that the police won’t bother me and” (the little man chuckled dryly) “so that the psychiatrists won’t either. I am a mathematician; an honest one.”

Zebatinsky smiled.

The numerologist said, “I build computers. I study probable futures.”

“What?”

“Does that sound worse than numerology to you? Why? Given enough data and a computer capable of sufficient number of operations in unit time, the future is predictable, at least in terms of probabilities. When you compute the motions of a missile in order to aim an anti-missile, isn’t it the future you’re predicting? The missile and antimissile would not collide if the future were predicted incorrectly. I do the same thing. Since I work with a greater number of variables, my results are less accurate.”

“You mean you’ll predict my future?”

“Very approximately. Once I have done that, I will modify the data by changing your name and no other fact about you. I throw that modified datum into the operation-program. Then I try other modified names. I study each modified future and find one that contains a greater degree of recognition for you than the future that now lies ahead of you. Or no, let me put it another way. I will find you a future in which the probability of adequate recognition is higher than the probability of that in your present future.”

“Why change my name?”

“That is the only change I ever make, for several reasons. Number one, it is a simple change. After all, if I make a great change or many changes, so many new variables enter that I can no longer interpret the result. My machine is still crude. Number two, it is a reasonable change. I can’t change your height, can I, or the color of your eyes, or even your temperament. Number three, it is a significant change. Names mean a lot to people. Finally, number four, it is a common change that is done every day by various people.”
