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 anti-missile 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."
Zebatinsky said, "What if you don't find a better future?"
"That is the risk you will have to take. You will be no worse off than now, my friend."
Zebatinsky stared at the little man uneasily, "I don't believe any of this. I'd sooner believe numerology."
The numerologist sighed. "I thought a person like yourself would feel more comfortable with the truth. I want to help you and there is much yet for you to do. If you believed me a numerologist, you would not follow through. I thought if I told you the truth you would let me help you."
Zebatinsky said, "If you can see the future - "
"Why am I not the richest man on earth? Is that it? But I am rich - in all I want. You want recognition and I want to be left alone. I do my work. No one bothers me. That makes me a billionaire. I need a little real money and this I get from people such as yourself. Helping people is nice and perhaps a psychiatrist would say it gives me a feeling of power and feeds my ego. Now - do you want me to help you?"
"How much did you say?"
"Fifty dollars. I will need a great deal of biographical information from you but I have prepared a form to guide you. It's a little long, I'm afraid. Still, if you can get it in the mail by the end of the week, I will have an answer for you by the - " (he put out his lower lip and frowned in mental calculation) "the twentieth of next month."
"Five weeks? So long?"
"I have other work, my friend, and other clients. If I were a fake, I could do it much more quickly. It is agreed then?"
Zebatinsky rose. "Well, agreed. - This is all confidential, now."
"Perfectly. You will have all your information back when I tell you what change to make and you have my word that I will never make any further use of any of it."
The nuclear physicist stopped at the door. "Aren't you afraid I might tell someone you're not a numerologist?"
The numerologist shook his head. "Who would believe you, my friend? Even supposing you were willing to admit to anyone that you've been here."
On the twentieth, Marshall Zebatinsky was at the paint-peeling door, glancing sideways at the shop front with the little card up against the glass reading "Numerology," dimmed and scarcely legible through the dust. He peered in, almost hoping that someone else would be there already so that he might have an excuse to tear up the wavering intention in his mind and go home.
He had tried wiping the thing out of his mind several times. He could never stick at filling out the necessary data for long. It was embarrassing to work at it. He felt incredibly silly filling out the names of his friends, the cost of his house, whether his wife had had any miscarriages, if so, when. He abandoned it.
But he couldn't stick at stopping altogether either. He returned to it each evening.
It was the thought of the computer that did it, perhaps; the thought of the infernal gall of the little man pretending he had a computer. The temptation to call the bluff, see what would happen, proved irresistible after all.
He finally sent off the completed data by ordinary mail, putting on nine cents worth of stamps without weighing the letter. If it comes back, he thought, I'll call it off.
It didn't come back.
He looked into the shop now and it was empty. Zebatinsky had no choice but to enter. A bell tinkled.
The old numerologist emerged from a curtained door. "Yes? - Ah, Dr. Zebatinsky."
"You remember me?" Zebatinsky tried to smile.
"Oh, yes."
"What's the verdict?"
The numerologist moved one gnarled hand over the other. "Before that, sir, there's a little - "
"A little matter of the fee?"
"I have already done the work, sir. I have earned the money."
Zebatinsky raised no objection. He was prepared to pay. If he had come this far, it would be silly to turn back just because of the money.
