He opened his eyes, "Did we make it?"
Hummin said dryly, "We're not dead," then walked away, his grip forcing Seldon to follow.
"I mean, did we get to the right level?"
"Of course."
"What would have happened if we were dropping down and someone else was moving upward?"
"There are two separate lanes. In one lane everyone drops at the same speed; in the other everyone rises at the same speed. The shaft clears only when there are no people within ten meters of each other. There is no chance of a collision if all works well."
"I didn't feel a thing."
"Why should you? There was no acceleration. After the first tenth of a second, you were at constant speed and the air in your immediate vicinity was moving down with you at the same speed."
"Marvelous."
"Absolutely. But uneconomic. And there seems no great pressure to increase the efficiency of the procedure and make it worthwhile. Everywhere one hears the same refrain. 'We can't do it. It can't be done.' It applies to everything." Hummin shrugged in obvious anger and said, "But we're here at the taxi rental. Let's get on with it."
10.
Seldon tried to look inconspicuous at the air-taxi rental terminus, which he found difficult. To look ostentatiously inconspicuous-to slink about, to turn his face away from all who passed, to study one of the vehicles overintently - was surely the way to invite attention. The way to behave was merely to assume an innocent normality.
But what was normality? He felt uncomfortable in his clothes. There were no pockets, so he had no place to put his hands. The two pouches, which dangled from his belt on either side, distracted him by hitting against him as he moved, so that he was continually thinking someone had nudged him.
He tried looking at women as they passed. They had no pouches, at least none dangling, but they carried little boxlike affairs that they occasionally clipped to one hip or another by some device he could not make out. It was probably pseudomagnetic, he decided. Their clothes were not particularly revealing, he noted regretfully, and not one had any sign of decolletage, although some dresses seemed to be designed to emphasize the buttocks.
Meanwhile, Hummin had been very businesslike, having presented the necessary credits and returned with the superconductive ceramic tile that would activate a specific air-taxi.
Hummin said, "Get in, Seldon," gesturing to a small two-seated vehicle.
Seldon asked, "Did you have to sign your name, Hummin?''
"Of course not. They know me here and don't stand on ceremony. "
"What do they think you're doing?"
"They didn't ask and I volunteered no information." He inserted the tile and Seldon felt a slight vibration as the air-taxi came to life.
"We're headed for D-7," said Hummin, making conversation.
Seldon didn't know what D-7 was, but he assumed it meant some route or other.
The air-taxi found its way past and around other ground-cars and finally moved onto a smooth upward-slanting track and gained speed. Then it lifted upward with a slight jolt.
Seldon, who had been automatically strapped in by a webbed restraint, felt himself pushed down into his seat and then up against the webbing.
He said, "That didn't feel like antigravity."
"It wasn't," said Hummin. "That was a small jet reaction. Just enough to take us up to the tubes."
What appeared before them now looked like a cliff patterned with cave openings, much like a checkerboard. Hummin maneuvered toward the D-7 opening, avoiding other air-taxis that were heading for other tunnels.
"You could crash easily," said Seldon, clearing his throat.
"So I probably would if everything depended on my senses and reactions, but the taxi is computerized and the computer can overrule me without trouble. The same is true for the other taxis. -Here we go."
They slid into D-7 as if they had been sucked in and the bright light of the open plaza outside mellowed, turning a warmer yellow hue.
Hummin released the controls and sat back. He drew a deep breath and said, "Well, that's one stage successfully carried through. We might have been stopped at the station. In here, we're fairly safe."
The ride was smooth and the walls of the tunnel slipped by rapidly. There was almost no sound, just a steady velvety whirr as the taxi sped along.
"How fast are we going?" asked Seldon.
Hummin cast an eye briefly at the controls. "Three hundred and fifty kilometers per hour."
"Magnetic propulsion?"
"Yes. You have it on Helicon, I imagine."
"Yes. One line. I've never been on it myself, though I've always meant to. I don't think it's anything like this."
"I'm sure it isn't. Trantor has many thousands of kilometers of these tunnels honeycombing the land subsurface and a number that snake under the shallower extensions of the ocean. It's the chief method of long-distance travel."
"How long will it take us?"
"To reach our immediate destination? A little over five hours."
"Five hours!" Seldon was dismayed.
"Don't be disturbed. We pass rest areas every twenty minutes or so where we can stop, pull out of the tunnel, stretch our feet, cat, or relieve ourselves. I'd like to do that as few times as possible, of course. "
They continued on in silence for a while and then Seldon started when a blaze of light flared at their right for a few seconds and, in the flash, he thought he saw two air-taxis.
"That was a rest area," said Hummin in answer to the unspoken question.
Seldon said, "Am I really going to be safe wherever it is you are taking me?"
Hummin said, "Quite safe from any open movement on the part of the Imperial forces. Of course, when it comes to the individual operator-the spy, the agent, the hired assassin-one must always be careful. Naturally, I will supply you with a bodyguard."
Seldon felt uneasy. "The hired assassin? Are you serious? Would they really want to kill me?"
Hummin said, "I'm sure Demerzel doesn't. I suspect he wants to use you rather than kill you. Still, other enemies may turn up or there may be unfortunate concatenations of events. You can't go through life sleepwalking."
Seldon shook his head and turned his face away. To think, only fortyeight hours ago he had been just an insignificant, virtually unknown Outworld mathematician, content only to spend his remaining time on Trantor sight-seeing, gazing at the enormity of the great world with his provincial eye. And now, it was finally sinking in: He was a wanted man, hunted by Imperial forces. The enormity of the situation seized him and he shuddered.
"And what about you and what you're doing right now?"
Hummin said thoughtfully, "Well, they won't feel kindly toward me, I suppose. I might have my head laid open or my chest exploded by some mysterious and never-found assailant."
Hummin said it without a tremor in his voice or a change in his calm appearance, but Seldon winced.
Seldon said, "I rather thought you would assume that might be in store for you. You don't seem to be . . . bothered by it."
"I'm an old Trantorian. I know the planet as well as anybody can. I know many people and many of them are under obligation to me. I like to think that I am shrewd and not easy to outwit. In short, Seldon, I am quite confident that I can take care of myself."
"I'm glad you feel that way and I hope you're justified in thinking so, Hummin, but I can't get it through my head why you're taking this chance at all. What am I to you? Why should you take even the smallest risk for someone who is a stranger to you?"
Hummin checked the controls in a preoccupied manner and then he faced Seldon squarely, eyes steady and serious. '
"I want to save you for the same reason that the Emperor wants to use you-for your predictive powers."
Seldon felt a deep pang of disappointment. This was not after all a question of being saved. He was merely the helpless and disputed prey of competing predators. He said angrily, "I will never live down that presentation at the Decennia
l Convention. I have ruined my life."
"No. Don't rush to conclusions, mathematician. The Emperor and his officers want you for one reason only, to make their own lives more secure. They are interested in your abilities only so far as they might be used to save the Emperor's rule, preserve that rule for his young son, maintain the positions, status, and power of his officials. I, on the other hand, want your powers for the good of the Galaxy.„
"Is there a distinction?" spat Seldon acidly.
And Hummin replied with the stern beginning of a frown, "If you do not see the distinction, then that is to your shame. The human occupants of the Galaxy existed before this Emperor who now rules, before the dynasty he represents, before the Empire itself. Humanity is far older than the Empire. It may even be far older than the twenty-five million worlds of the Galaxy. There are legends of a time when humanity inhabited a single world."
"Legends!" said Seldon, shrugging his shoulders.
"Yes, legends, but I see no reason why that may not have been so in fact, twenty thousand years ago or more. I presume that humanity did not come into existence complete with knowledge of hyperspatial travel. Surely, there must have been a time when people could not travel at superluminal velocities and they must then have been imprisoned in a single planetary system. And if we look forward in time, the human beings of the worlds of the Galaxy will surely continue to exist after you and the Emperor are dead, after his whole line comes to an end, and after the institutions of the Empire itself unravel. In that case, it is not important to worry overmuch about individuals, about the Emperor and the young Prince Imperial. It is not important to worry even about the mechanics of Empire. What of the quadrillions of people that exist in the Galaxy? What of them?"
Seldon said, "Worlds and people would continue, I presume."
"Don't you feel any serious need of probing the possible conditions under which they would continue to exist.
"One would assume they would exist much as they do now."
"One would assume. But could one know by this art of prediction that you speak of?"
"Psychohistory is what I call it. In theory, one could."
"And you feel no pressure to turn that theory into practice."
"I would love to, Hummin, but the desire to do so doesn't automatically manufacture the ability to do so. I told the Emperor that psychohistory could not be turned into a practical technique and I am forced to tell you the same thing."
"And you have no intention of even trying to find the technique?"
"No, I don't, any more than I would feel I ought to try to tackle a pile of pebbles the size of Trantor, count them one by one, and arrange them in order of decreasing mass. I would know it was not something I could accomplish in a lifetime and I would not be fool enough to make a pretense of trying."
"Would you try if you knew the truth about humanity's situation?"
"That's an impossible question. What it the truth about humanity's situation? Do you claim to know it?"
"Yes, I do. And in five words." Hummin's eyes faced forward again, turning briefly toward the blank changelessness of the tunnel as it pushed toward them, expanding until it passed and then dwindling as it slipped away. He then spoke those five words grimly.
He said, "The Galactic Empire is dying."

University
STREELING UNIVERSITY-. . . An institution of higher learning in the Streeling Sector of ancient Trantor . . . Despite all these claims to fame in the fields of the humanities and silences alike, is is not for those that the University looms large in today's consciousness. It would probably have come as a coral surprise to the generations of scholars ac the University to know that in lacer times Streeling University would be most remembered because a certain Hari Seldon, during the period of The Flight, had been in residence there for a shore time.
ENCYCLOPEDIA GALACTICA
11.
Hari Seldon remained uncomfortably silent for a while after Hummin's quiet statement. He shrank within himself in sudden recognition of his own deficiencies.
He had invented a new science: psychohistory. He had extended the laws of probability in a very subtle manner to take into account new complexities and uncertainties and had ended up with elegant equations in innumerable unknowns. -Possibly an infinite number; he couldn't tell.
But it was a mathematical game and nothing more.
He had psychohistory--or at least the basis of psychohistory but only as a mathematical curiosity. Where was the historical knowledge that could perhaps give some meaning to the empty equations?
He had none. He had never been interested in history. He knew the outline of Heliconian history. Courses in that small fragment of the human story had, of course, been compulsory in the Heliconian schools. But what was there beyond that? Surely what else he had picked up was merely the bare skeletons that everyone gatheredhalf legend, the other half surely distorted.
Still, how could one say that the Galactic Empire was dying? It had existed for ten thousand years as an accepted Empire and even before that, Trantor, as the capital of the dominating kingdom, had held what was a virtual empire for two thousand years. The Empire had survived the early centuries when whole sections of the Galaxy would now and then refuse to accept the end of their local independence. It had survived the vicissitudes that went with the occasional rebellions, the dynastic wars, some serious periods of breakdown. Most worlds had scarcely been troubled by such things and Trantor itself had grown steadily until it was the worldwide human habitation that now called itself the Eternal World.
To be sure, in the last four centuries, turmoil had increased somehow and there had been a rash of Imperial assassinations and takeovers. But even that was calming down and right now the Galaxy was as quiet as it had ever been. Under Cleon I and before him under his father, Stanel VI, the worlds were prosperous-and Cleon himself was not considered a tyrant. Even those who disliked the Imperium as an institution rarely had anything truly bad to say about Cleon, much as they might inveigh against Eto Demerzel.
Why, then, should Hummin say that the Galactic Empire was dyingand with such conviction?
Hummin was a journalist. He probably knew Galactic history in some detail and he had to understand the current situation in great detail. Was it this that supplied him with the knowledge that lay behind his statement? In that case, just what was the knowledge?
Several times Seldon was on the point of asking, of demanding an answer, but there was something in Hummin's solemn face that stopped him. And there was something in his own ingrained belief that the Galactic Empire was a given, an axiom, the foundation stone on which all argument rested that prevented him too. After all, if that was wrong, he didn't want to know.
No, he couldn't believe that he was wrong. The Galactic Empire could no more come to an end than the Universe itself could. Or, if the Universe did end, then-and only then-would the Empire end.
Seldon closed his eyes, attempting to sleep but, of course, he could not. Would he have to study the history of the Universe in order to advance his theory of psychohistory?
How could he? Twenty-five million worlds existed, each with its own endlessly complex history. How could he study all that? There were book-films in many volumes, he knew, that dealt with Galactic history. He had even skimmed one once for some now-forgotten reason and had found it too dull to view even halfway through.
The book-films had dealt with important worlds. With some, it dealt through all or almost all their history; with others, only as they gained importance for a time and only till they faded away. He remembered having looked up Helicon in the index and having found only one citation. He had punched the keys that would turn up that citation and found Helicon included in a listing of worlds which, on one occasion, had temporarily lined up behind a certain claimant to the Imperial throne who had failed to make good his claim. Helicon had escaped retribution on that occasion, probably because it was not even sufficiently important to be punished.
/> What good was such a history? Surely, psychohistory would have to take into account the actions and reactions and interactions of each world-eacb and every world. How could one study the history of twentyfive million worlds and consider all their possible interactions? It would surely be an impossible task and this was just one more reinforcement of the general conclusion that psychohistory was of theoretical interest but could never be put to any practical use.
Seldon felt a gentle push forward and decided that the air-taxi must be decelerating.
"What's up?" he asked.
"I think we've come far enough," said Hummin, "to risk a small stopover for a bite to eat, a glass of something or other, and a visit to a washroom."
And, in the course of the next fifteen minutes, during which the air-taxi slowed steadily, they came to a lighted recess. The taxi swerved inward and found a parking spot among five or six other vehicles.
12.
Hummin's practiced eye seemed to take in the recess, the other taxis, the diner, the walkways, and the men and women all at a glance. Seldon, trying to look inconspicuous and again not knowing how, watched him, trying not to do so too intently.
When they sat down at a small table and punched in their orders, Seldon, attempting to sound indifferent, said, "Everything okay?"
"Seems so," said Hummin.
"How can you tell?"
Hummin let his dark eyes rest on Seldon for a moment. "Instinct," he said. "Years of news gathering. You look and know, 'No news here.'"
Seldon nodded and felt relieved. Hummin might have said it sardonically, but there must be a certain amount of truth to it.
His satisfaction did not last through the first bite of his sandwich. He looked up at Hummin with his mouth full and with a look of hurt surprise on his face.
Hummin said, "This is a wayside diner, my friend. Cheap, fast, and not very good. The food's homegrown and has an infusion of rather sharp yeast. Trantorian palates are used to it."
Seldon swallowed with difficulty. "But back in the hotel-"
"You were in the Imperial Sector, Seldon. Food is imported there and where microfood is used it is high-quality. It is also expensive. "
