Prelude to Foundation

air-jet. And regardless of how safe it is here, I’d feel better if Demerzel didn’t know exactly where you were.

—As a matter of fact, we’re not done yet. We’re going to take the Expressway for the final stage.”

Seldon knew the expression. “One of those open monorails moving on an electromagnetic field, right?”

“Right.”

“We don’t have them on Helicon. Actually, we don’t need them there. I rode on an Expressway the first day I was on Trantor. It took me from the airport to the hotel. It was rather a novelty, but if I were to use it all the time, I imagine the noise and crowds would become overpowering.”

Hummin looked amused. “Did you get lost?”

“No, the signs were useful. There was trouble getting on and off, but I was helped. Everyone could tell I was an Outworlder by my clothes, I now realize. They seemed eager to help, though; I guess because it was amusing to watch me hesitate and stumble.”

“As an expert in Expressway travel by now, you will neither hesitate nor stumble.” Hummin said it pleasantly enough, though there was a slight twitch to the corners of his mouth. “Come on, then.”

They sauntered leisurely along the walkway, which was lit to the extent one might expect of an overcast day and that brightened now and then as though the sun occasionally broke through the clouds. Automatically, Seldon looked upward to see if that were indeed the case, but the “sky” above was blankly luminous.

Hummin saw this and said, “This change in brightness seems to suit the human psyche. There are days when the street seems to be in bright sunlight and days when it is rather darker than it is now.”

“But no rain or snow?”

“Or hail or sleet. No. Nor high humidity nor bitter cold. Trantor has its points, Seldon, even now.”

There were people walking in both directions and there were a considerable number of young people and also some children accompanying the adults, despite what Hummin had said about the birthrate. All seemed reasonably prosperous and reputable. The two sexes were equally represented and the clothing was distinctly more subdued than it had been in the Imperial Sector. His own costume, as chosen by Hummin, fit right in. Very few were wearing hats and Seldon thankfully removed his own and swung it at his side.

There was no deep abyss separating the two sides of the walkway and as Hummin had predicted in the Imperial Sector, they were walking at what seemed to be ground level. There were no vehicles either and Seldon pointed this out to Hummin.

Hummin said, “There are quite a number of them in the Imperial Sector because they’re used by officials. Elsewhere, private vehicles are rare and those that are used have separate tunnels reserved for them. Their use is not really necessary, since we have Expressways and, for shorter distances, moving corridors. For still shorter distances, we have walkways and we can use our legs.”

Seldon heard occasional muted sighs and creaks and saw, some distance off, the endless passing of Expressway cars.

“There it is,” he said, pointing.

“I know, but let us move on to a boarding station. There are more cars there and it is easier to get on.”

Once they were safely ensconced in an Expressway car, Seldon turned to Hummin and said, “What amazes me is how quiet the Expressways are. I realize that they are mass-propelled by an electromagnetic field, but it seems quiet even for that.” He listened to the occasional metallic groan as the car they were on shifted against its neighbors.

“Yes, it’s a marvelous network,” said Hummin, “but you don’t see it at its peak. When I was younger, it was quieter than it is now and there are those who say that there wasn’t as much as a whisper fifty years ago—though I suppose we might make allowance for the idealization of nostalgia.”

“Why isn’t it that way now?”

“Because it isn’t maintained properly. I told you about decay.”

Seldon frowned. “Surely, people don’t sit around and say, ‘We’re decaying. Let’s let the Expressways fall apart.’?”

“No, they don’t. It’s not a purposeful thing. Bad spots are patched, decrepit coaches refurbished, magnets replaced. However, it’s done in more slapdash fashion, more carelessly, and at greater intervals. There just aren’t enough credits available.”

“Where have the credits gone?”

“Into other things. We’ve had centuries of unrest.

The navy is much larger and many times more expensive than it once was. The armed forces are much better-paid, in order to keep them quiet. Unrest, revolts, and minor blazes of civil war all take their toll.”

“But it’s been quiet under Cleon. And we’ve had fifty years of peace.”

“Yes, but soldiers who are well-paid would resent having that pay reduced just because there is peace. Admirals resist mothballing ships and having themselves reduced in rank simply because there is less for them to do. So the credits still go—unproductively—to the armed forces and vital areas of the social good are allowed to deteriorate. That’s what I call decay. Don’t you? Don’t you think that eventually you would fit that sort of view into your psychohistorical notions?”

Seldon stirred uneasily. Then he said, “Where are we going, by the way?”

“Streeling University.”

“Ah, that’s why the sector’s name was familiar. I’ve heard of the University.”

“I’m not surprised. Trantor has nearly a hundred thousand institutions of higher learning and Streeling is one of the thousand or so at the top of the heap.”

“Will I be staying there?”

“For a while. University campuses are unbreachable sanctuaries, by and large. You will be safe there.”

“But will I be welcome there?”

“Why not? It’s hard to find a good mathematician these days. They might be able to use you. And you might be able to use them too—and for more than just a hiding place.”

“You mean, it will be a place where I can develop my notions.”

“You have promised,” said Hummin gravely.

“I have promised to try,” said Seldon and thought to himself that it was about like promising to try to make a rope out of sand.

Conversation had run out after that and Seldon watched the structures of the Streeling Sector as they passed. Some were quite low, while some seemed to brush the “sky.” Wide crosspassages broke the progression and frequent alleys could be seen.

At one point, it struck him that though the buildings rose upward they also swept downward and that perhaps they were deeper than they were high. As soon as the thought occurred to him, he was convinced it was true.

Occasionally, he saw patches of green in the background, farther back from the Expressway, and even small trees.

He watched for quite a while and then became aware that the light was growing dimmer. He squinted about and turned to Hummin, who guessed the question.

“The afternoon is waning,” he said, “and night is coming on.”

Seldon’s eyebrows raised and the corners of his mouth turned downward. “That’s impressive. I have a picture of the entire planet darkening and then, some hours from now, lighting up again.”

Hummin smiled his small, careful smile. “Not quite, Seldon. The planet is never turned off altogether—or turned on either. The shadow of twilight sweeps across the planet gradually, followed half a day later by the slow brightening of dawn. In fact, the effect follows the actual day and night above the domes quite closely, so that in higher altitudes day and night change length with the seasons.”

Seldon shook his head. “But why close in the planet and then mimic what would be in the open?”

“I presume because people like it better that way. Trantorians like the advantages of being enclosed, but they don’t like to be reminded of it unduly, just the same. You know very little about Trantorian psychology,
