Prelude to Foundation

“We’re talking about social pressures. I’m not exactly a Galactic traveler, but I’ve had to involve myself in a great deal of social history. On the planet of Derowd, there was a time when premarital sex was absolutely free. Multiple sex was allowed for the unmarried and public sex was frowned upon only when traffic was blocked: And yet, after marriage, monogamy was absolute and unbroken. The theory was that by working off all one’s fantasies first, one could settle down to the serious business of life.”

“Did it work?”

“About three hundred years ago that stopped, but some of my colleagues say it stopped through external pressure from other worlds who were losing too much tourist business to Derowd. There is such a thing as overall Galactic social pressure too.”

“Or perhaps economic pressure, in this case.”

“Perhaps. And being at the University, by the way, I get a chance to study social pressures, even without being a Galactic traveler. I meet people from scores of places inside and outside of Trantor and one of the pet amusements in the social science departments is the comparison of social pressures.

“Here in Mycogen, for instance, I have the impression that sex is strictly controlled and is permitted under only the most stringent rules, all the more tightly enforced because it is never discussed. In the Streeling Sector, sex is never discussed either, but it isn’t condemned. In the Jennat Sector, where I spent a week once doing research, sex is discussed endlessly, but only for the purpose of condemning it. I don’t suppose there are any two sectors in Trantor-or any two worlds outside Trantor-in which attitudes toward sex are completely duplicated.”

Seldon said, “You know what you make it sound like? It would appear-”

Dors said, “I’ll tell you how it appears. All this talk of sex makes one thing clear to me. I’m simply not going to let you out of my sight anymore.”

“What?”

“Twice I let you go, the first time through my own misjudgment and the second because you bullied me into it. Both times it was clearly a mistake. You know what happened to you the first time.”

Seldon said indignantly, “Yes, but nothing happened to me the second time.”

“You nearly got into a lot of trouble. Suppose you had been caught indulging in sexual escapades with a Sister?”

“It wasn’t a sexual-”

“You yourself said she was in a high state of sexual excitement.”

“But-”

“It was wrong. Please get it through your head, Hari. From now on, you go nowhere without me.”

“Look,” said Seldon freezingly, “my object was to find out about Mycogenian history and as a result of the so-called sexual escapade with a Sister, I have a book-the Book.”

“The Book! True, there’s the Book. Let’s see it.”

Seldon produced it and Dors thoughtfully hefted it.

She said, “It might not do us any good, Hari. This doesn’t look as though it will fit any projector I’ve ever encountered. That means you’ll have to get a Mycogenian projector and they’ll want to know why you want it. They’ll then find out you have this Book and they’ll take it away from you.”

Seldon smiled. “If your assumptions were correct, Dors, your conclusions would be inescapable, but it happens that this is not the kind of book you think it is. It’s not meant to be projected. The material is printed on various pages and the pages are turned. Raindrop Forty-Three explained that much to me.”

“A print-book!” It was hard to tell whether Dors was shocked or amused. “That’s from the Stone Age.”

“It’s certainly pre-Empire,” said Seldon, “but not entirely so. Have you ever seen a print-book?”

“Considering that I’m a historian? Of course, Hari.”

“Ah, but like this one?”

He handed over the Book and Dors, smiling, opened it-then turned to another page-then flipped the pages. “Its blank,” she said.

“It appears to be blank. The Mycogenians are stubbornly primitivistic, but not entirely so. They will keep to the essence of the primitive, but have no objection to using modern technology to modify it for convenience’s sake. Who knows?”

“Maybe so, Hari, but I don’t understand what you’re saying.”

“The pages aren’t blank, they’re covered with microprint. Here, give it back. If I press this little nubbin on the inner edge of the cover- Look!”

The page to which the book lay open was suddenly covered with lines of print that rolled slowly upward.

Seldon said, “You can adjust the rate of upward movement to match your reading speed by slightly twisting the nubbin one way or the other. When the lines of print reach their upward limit when you reach the bottom line, that is-they snap downward and turn off. You turn to the next page and continue.”

“Where does the energy come from that does all this?”

“It has an enclosed microfusion battery that lasts the life of the book.”

“Then when it runs down-”

“You discard the book, which you may be required to do even before it runs down, given wear and tear, and get another copy. You never replace the battery.”
