Prelude to Foundation - Isaac Asimov [61]
Seldon's own Helicon was somewhat larger by a percent or two than Trantor was and had a smaller ocean. The Heliconian land surface was perhaps 10 percent larger than the Trantorian. But Helicon was sparsely populated, its surface only sprinkled with scattered cities; Trantor was all city. Where Helicon was divided into twenty administrative sectors; Trantor had over eight hundred and every one of those hundreds was itself a complex of subdivisions.
Finally Seldon said in some despair, "Perhaps it might be best, Hummin, m chose which candidate for my supposed abilities is most nearly benign, hand me over to that one, and count on him to defend me against the rest."
Hummm looked up and said in utmost seriousness, "That is not necessary. I know the candidate who is most nearly benign and he already has you."
Seldon smiled. "Do you place yourself on the same level with the Mayor of Wye and the Emperor of all the Galaxy?"
"In point of view of position, no. But as far as the desire to control you is concerned, I rival them. They, however, and anyone else I can think of want you in order to strengthen their own wealth and power, while I have no ambitions at all, except for the good of the Galaxy."
"I suspect," said Seldon dryly, "that each of your competitors-if asked-would insist that he too was thinking only of the good of the Galaxy."
"I am sure they would," said Hummin, "but so far, the only one of my competitors, as you call them, whom you have met is the Emperor and he was interested in having you advance fictionalized predictions that might stabilize his dynasty. I do not ask you for anything like that. I ask only that you perfect your psychohistorical technique so that mathematically valid predictions, even if only statistical in nature, can be made."
"True. So far, at least," said Seldon with a half-smile.
"Therefore, I might as well ask: How are you coming along with that task? Any progress?"
Seldon was uncertain whether to laugh or cage. After a pause, he did neither, but managed to speak calmly. "Progress? In less than two months? Hummin, this is something that might easily take me my whole life and the lives of the next dozen who follow me. -And even then end in failure."
"I'm not talking about anything as final as a solution or even as hopeful as the beginning of a solution. You've said flatly a number of times that a useful psychohistory is possible but impractical. All I am asking is whether there now seems any hope that it can be made practical.'
"Frankly, no."
Dors said, "Please excuse me. I am not a mathematician, so 1 hope this is not a foolish question. How can you know something is both possible and impractical? I've heard you say that, in theory, you might personally meet and greet all the people in the Empire, but that it is not a practical feat because you couldn't live long enough to do it. But how can you tell that psychohistory is something of this sort?"
Seldon looked at Dors with some incredulity. "Do you want that explained."
"Yes," she said, nodding her head vigorously so that her curled hair vibrated.
"As a matter of fact," said Hummin, "so would L"
"Without mathematics?" said Seldon with just a trace of a smile.
"Please," said Hummin.
"Well-" He retired into himself to choose a method of presentation. Then he said,- If you want to understand some aspect of the Universe, it helps if you simplify it as much as possible and include only those properties and characteristics that are essential to understanding. If you want to determine how an object drops, you don't concern yourself with whether it is new or old, is red or green, or has an odor or not. You eliminate those things and thus do trot needlessly complicate matters. The simplification you can call a model or a simulation and you can present it either as an actual representation on a computer screen or as a mathematical relationship. If you consider the primitive theory of nonrelativistic gravitation "
Don said at once, "You promised
