The End of Eternity

Chapter 14

"Or B, the later individual, may see A while A does not see B. Here, too, no serious consequences need be expected. B, seeing A, sees him in a position and engaged in activity of which he already has knowledge. Nothing new is involved.

"The third and fourth possibilities are that A sees B, while B does not see A, and that A and B see one another. In each possibility, the serious point is that A has seen B; the man at an earlier stage in his physiological existence sees himself at a later stage. Observe that he has learned he will be alive at the apparent age of B. He knows he will live long enough to perform the action he has witnessed. Now a man in knowing his own future in even the slightest detail can act on that knowledge and therefore changes his future. It follows that Reality must be changed to the extent of not allowing A and B to meet or, at the very least, of preventing A from seeing B. Then, since nothing in a Reality made un-Real can be detected, A never has met B. Similarly, in every apparent paradox of Time-travel, Reality always changes to avoid the paradox and we come to the conclusion that there are no paradoxes in Time-travel and that there can be none."

Sennor looked well pleased with himself and his exposition, but Twis sell rose to his feet.

Twis sell said, "I believe, gentlemen, that time presses."

Far more suddenly than Harlan would have thought the lunch was over. Five of the subcommittee members filed out, nodding at him, with the air of those whose curiosity, mild at best, had been a.s.suaged. Only Sennor held out a hand and added a gruff "Good day, young man" to the nod.



With mixed feelings Harlan watched them go. What had been the purpose of the luncheon? Most of all, why the reference to men meeting themselves? They had made no mention of Noys. Were they there, then, only to study him? Survey him from top to bottom and leave him to Twissell"s judging?

Twissell returned to the table, empty now of food and cutlery. He was alone with Harlan now, and almost as though to symbolize that he wielded a new cigarette between his fingers.

He said, "And now to work, Harlan. We have a great deal to do."

But Harlan would not, could not, wait longer. He said flatly, "Before we do anything, I have something to say."

Twissell looked surprised. The skin of his face puckered up about his faded eyes, and he tamped at the ash end of his cigarette thoughtfully.

He said, "By all means, speak if you wish, but first, sit down, sit down, boy."

Technician Andrew Harlan did not sit down. He strode up and back the length of the table, biting off his sentences hard to keep them from boiling and bubbling into incoherence. Senior Computer Laban Twissell"s age-yellowed pippin of a head turned back and forth as he followed the other"s nervous stride.

Harlan said, "For weeks now I"ve been going through films on the history of mathematics. Books from several Realities of the 575th. The Realities don"t matter much. Mathematics doesn"t change. The order of its development doesn"t change either. No matter how else the Realities shifted, mathematical history stayed about the same. The mathematicians changed; different ones switched discoveries, but the end results---- Anyway, I pounded a lot of it into my head. How does that strike you?"

Twissell frowned and said, "A queer occupation for a Technician?"

"But I"m not just a Technician," said Harlan. "You know that."

"Go on," said Twissell and he looked at the timepiece he wore. The fingers that held his cigarette played with it with unwonted nervousness.

Harlan said, "There was a man named Vikkor Mallansohn who lived in the 24th Century. That was part of the Primitive era, you know. The thing he is known best for is the fact that he first successfully built a Temporal Field. That means, of course, that he invented Eternity, since Eternity is only one tremendous Temporal Field shortcircuiting ordinary Time and free of the limitations of ordinary Time."

"You were taught this as a Cub, boy."

"But I was not taught that Vikkor Mallansohn could not possibly have invented the Temporal Field in the 24th Century. Nor could anyone have. The mathematical basis for it didn"t exist. The fundamental Lefebvre equations did not exist; nor could they exist until the researches of Jan Verdeer in the 27th Century."

If there was one sign by which Senior Computer Twissell could indicate complete astonishment, it was that of dropping his cigarette. He dropped it now. Even his smile was gone.

He said, "Were you taught the Lefebvre equations, boy?"

"No. And I don"t say I understand them. But they"re necessary for the Temporal Field. I"ve learned that. And they weren"t discovered till the 27th. I know that, too."

Twissell bent to pick up his cigarette and regarded it dubiously. "What if Mallansohn had stumbled on the Temporal Field without being aware of the mathematical justification? What if it were simply an empirical discovery? There have been many such."

"I"ve thought of that. But after the Field was invented, it took three centuries to work out its implications and at the end of that time there was no one way in which Mallansohn"s Field could be improved on. That could not be coincidence. In a hundred ways, Mallansohn"s design showed that he must have used the Lefebvre equations. If he knew them or bad developed them without Verdeer"s work, which is impossible, why didn"t he say so?"

Twissell said, "You insist on talking like a mathematician. Who told you all this?"

"I"ve been viewing films."

"No more?"

"And thinking."

"Without advanced mathematical training? I"ve watched you closely for years, boy, and would not have guessed that particular talent of yours. Go on."

"Eternity could never have been established without Mallansohn"s discovery of the Temporal Field. Mallansohn could never have accomplished this without a knowledge of mathematics that existed only in his future. That"s number one. Meanwhile, here in Eternity at this moment, there is a Cub who was selected as an Eternal against all the rules, since he was overage and married, to boot. You are educating him in mathematics and in Primitive sociology. That"s number two."

"Well?"

"I say that it is your intention to send him back into Time somehow, back past the downwhen terminus of Eternity, back to the 24th. It is your intention to have the Cub, Cooper, teach the Lefebvre equations to Mallansohn. You see, then," Harlan added with tense pa.s.sion, "that my own position as expert in the Primitive and my knowledge of that position ent.i.tles me to special treatment. Very special treatment."

"Father Time!" muttered Twissell.

"It"s true, isn"t it? We come full circle, _with my help_. Without it . . ." He let the sentence hang.

"You come so close to the truth," said Twissell. "Yet I could swear there was nothing to indicate----" He fell into a study in which neither Harlan nor the outside world seemed to play a part.

Harlan said quickly, "Only close to the truth? It _is_ the truth." He could not tell why he was so certain of the essentials of what he said, even quite apart from the fact that he so desperately wanted it to be so.

Twissell said, "No, no, not the exact truth. The Cub, Cooper, is not going back to the 24th to teach Mallansohn anything."

"I don"t believe you."

"But you must. You must see the importance of this. I want your co-operation through what is left of the project. You see, Harlan, the situation is more full circle than you imagine. Much more so, boy. Cub Brinsley Sheridan Cooper _is_ Vikkor Mallansohn!"

12 The Beginning of Eternity

Harlan would not have thought that Twissell could have said anything at that moment that could have surprised him. He was wrong.

He said, "Mallansohn. He--"

Twissell, having smoked his cigarette to a stub, produced another and said, "Yes, Mallansohn. Do you want a quick summary of Mallansohn"s life? Here it is. He was born in the 78th, spent some time in Eternity, and died in the 24th."

Twissell"s small hand placed itself lightly on Harlan"s elbow and his gnomish face broke into a wrinkled extension of his usual smile. "But come, boy, physiotime pa.s.ses even for us and we are not completely masters of ourselves this day. Won"t you come with me to my office?"

He led the way and Harlan followed, not entirely aware of the opening doors and the moving ramps.

He was relating the new information to his own problem and plan of action. With the pa.s.sing of the first moment of disorientation his resolution returned. After all, how did this change things except to make his own importance to Eternity still more crucial, his value higher, his demands more sure to be met, Noys more certain to be bartered back to him.

Noys!

Father Time, they must not harm her! She seemed the only real part of his life. All Eternity beside was only a filmy fantasy, and not a worth-while one, either.

When he found himself in Computer Twissell"s office, he could not clearly recall how it had come about that he had pa.s.sed from the dining area here. Though he looked about and tried to make the office grow real by sheer force of the ma.s.s of its contents, it still seemed but another part of a dream that had outlived its usefulness.

Twissell"s office was a clean, long room of porcelain asepsis. One wall of the office was crowded from floor to ceiling and wall to distant wall with the computing micro-units which, together, made up the largest privately operated Computaplex in Eternity and, indeed, one of the largest altogether. The opposite wall was crammed with reference films. Between the two what was left of the room was scarcely more than a corridor, broken by a desk, two chairs, recording and projecting equipment, and an unusual object the like of which Harlan was not familiar with and which did not reveal its use until Twissell flicked the remnants of a cigarette into it.

It flashed noiselessly and Twissell, in his usual prestidigitational fashion, held another in his hands.

Harlan thought: To the point, now.

He began, a trifle too loudly, a bit too truculently, "There is a girl in the 482nd----"

Twissell frowned, waved one hand quickly as though brushing an unpleasant matter hastily to one side. "I know, I know. She will not be disturbed, nor you. All will be well. I will see to it."

"Do you mean----"

"I tell you I know the story. If the matter has troubled you, it need trouble you no more."

Harlan stared at the old man, stupefied. Was this all? Though he had thought intently of the immensity of his power, he had not expected so clear a demonstration.

But Twissell was talking again.

"Let me tell you a story," he began, with almost the tone he would have used in addressing a newly inducted Cub. "I had not thought this would be necessary, and perhaps it still isn"t, but your own researches and insight deserve it."

He stared at Harlan quizzically and said, "You know, I still can"t quite believe that you worked this out on your own," then went on: "The man most of Eternity knows as Vikkor Mallansohn left the record of his life behind him after he died. It was not quite a diary, not quite a biography. It was more of a guide, bequeathed to the Eternals he knew would someday exist. It was enclosed in a volume of Time-stasis which could be opened only by the Computers of Eternity, and which therefore remained untouched for three Centuries after his death, until Eternity was established and Senior Computer Henry Wadsman, the first of the great Eternals, opened it. The doc.u.ment has been pa.s.sed along in strictest security since, along a line of Senior Computers ending with myself. It is referred to as the Mallansohn memoir.

"The memoir tells the story of a man named Brinsley Sheridan Cooper, born in the 78th, inducted as a Cub into Eternity at the age of twenty-three, having been married for a little over a year, but having been, as yet, childless.

"Having entered Eternity, Cooper was trained in mathematics by a Computer named Laban Twissell and in Primitive sociology by a Technician named Andrew Harlan. After a thorough grounding in both disciplines, and in such matters as temporal engineering as well, he was sent back to the 24th to teach certain necessary techniques to a Primitive scientist named Vikkor Mallansohn.

"Once having reached the 24th, he embarked first on a slow process of adjusting himself to the society. In this he benefited a great deal from the training of Technician Harlan and the detailed advice of Computer Twissell, who seemed to have an uncanny insight into some of the problems he was to face.

"After the pa.s.sage of two years, Cooper located one Vikkor Mallansohn, an eccentric recluse in the California backwoods, relationless and friendless but gifted with a daring and unconventional mind. Cooper made friends slowly, acclimated the man to the thought of having met a traveler from the future still more slowly, and set about teaching the man the mathematics he must know.

"With the pa.s.sage of time, Cooper adopted the other"s habits, learned to shift for himself with the help of a clumsy Diesel-oil electric generator and with wired electrical appliances which freed them of dependence on power beams.

"But progress was slow and Cooper found himself something less than a marvelous teacher. Mallansohn grew morose and unco-operative and then one day died, quite suddenly, in a fall down a canyon of the wild, mountainous country in which they lived. Cooper, after weeks of despair, with the ruin of his lifework and, presumably, of all Eternity, staring him in the eye, decided on a desperate expedient. He did not report Mallansohn"s death. Instead, he slowly took to building, out of the materials at hand, a Temporal Field.

"The details do not matter. He succeeded after mountains of drudgery and improvisation and took the generator to the California Inst.i.tute of Technology, just as years before he had expected the real Mallansohn to do.

"You know the story from your own studies. You know of the disbelief and rebuffs he first met, his period under observation, his escape and the near-loss of his generator, the help he received from the man at the lunch counter whose name he never learned, but who is now one of Eternity"s heroes, and of the final demonstration for Professor Zimbalist, in which a white mouse moved backward and forward in time. I won"t bore you with any of that.

"Cooper used the name of Vikkor Mallansohn in all this because it gave him a background and made him an authentic product of the 24th. The body of the real Mallansohn was never recovered.

"In the remainder of his life, he cherished his generator and cooperated with the Inst.i.tute scientists in duplicating it. He dared do no more than that. He could not teach them the Lefebvre equations without outlining three Centuries of mathematical development that was to come. He could not, dared not hint at his true origin. He dared not do more than the real Vikkor Mallansohn had, to his knowledge, done.

"The men who worked with him were frustrated to find a man who could perform so brilliantly and yet was unable to explain the whys of his performance. And he himself was frustrated too, because he foresaw, without in any way being able to quicken, the work that would lead, step by step, to the cla.s.sic experiments of Jan Verdeer, and how from that the great Antoine Lefebvre would construct the basic equations of Reality. And how, after that, Eternity would be constructed.

"It was only toward the end of his long life that Cooper, staring into a Pacific sunset (he describes the scene in some detail in his memoir) came to the great realization that he was Vikkor Mallansohn; he was not a subst.i.tute but the man himself. The name might not be his, but the man history called Mallansohn was really Brinsley Sheridan Cooper.

"Fired with that thought, and with all that implied, anxious that the process of establishing Eternity be somehow quickened, improved, and made more secure, he wrote his memoir and placed it in a cube of Time-stasis in the living room of his house.

"And so the circle was closed. Cooper-Mallansohn"s intentions in writing the memoir were, of course, disregarded. Cooper must go through his life exactly as he had gone through it. Primitive Reality allows of no changes. At this moment in physiotime, the Cooper you know is unaware of what lies ahead of him. He believes he is only to instruct Mallansohn and to return. He will continue to believe so until the years teach him differently and he sits down to write his memoir.

"The intention of the circle in Time is to establish the knowledge of Time-travel and of the nature of Reality, to build Eternity, ahead of its natural Time. Left to itself, mankind would not have learned the truth about Time before their technological advances in other directions had made racial suicide inevitable."

Harlan listened intently, caught up in the vision of a mighty circle in Time, closed upon itself, and traversing Eternity in part of its course. He came as close to forgetting Noys, for the moment, as he ever could.

He asked, "Then you knew all along everything you were to do, everything I was to do, everything I _have_ done."

Twissell, who seemed lost in his own telling of the tale, his eyes peering through a haze of bluish tobacco smoke, came slowly to life. His old, wise eyes fixed themselves on Harlan and he said reproachfully, "No, of course not. There was a lapse of decades of physiotime between Cooper"s stay in Eternity and the moment when he wrote his memoir. He could remember only so much, and only what he himself had witnessed. You should realize that."

Twissell sighed and he drew a gnarled finger through a line of updrafting smoke, breaking it into little turbulent swirls. "It worked itself out. First, I was found and brought to Eternity. When, in the fullness of physiotime, I became a Senior Computer, I was given the memoir and placed in charge. I had been described as in charge, so I was placed in charge. Again in the fullness of physiotime, you appeared in the changing of a Reality (we had watched your earlier a.n.a.logues carefully), and then Cooper.

"I filled in the details by using my common sense and the services of the Computaplex. How carefully, for instance, we instructed Educator Yarrow in his part while betraying none of the significant truth. How carefully, in his turn, he stimulated your interest in the Primitive.

"How carefully we had had to keep Cooper from learning anything he did not prove he had learned by reference in the memoir." Twissell smiled sadly. "Sennor amuses himself with matters such as this. He calls it the reversal of cause and effect. Knowing the effect, one adjusts the cause. Fortunately, I am not the cobweb spinner Sennor is.

"I was pleased, boy, to find you so excellent an Observer and Technician. The memoir had not mentioned that since Cooper had no opportunity to observe your work or evaluate it. This suited me. I could use you in a more ordinary task that would make your essential one less noticeable. Even your recent stay with Computer Finge fitted in. Cooper mentioned a period of your absence during which his mathematical studies were so sharpened that he longed for your return. Once, though, you frightened me."

Harlan said, at once, "You mean the time I took Cooper along the kettle ways."

"How do you come to guess that?" demanded Twissell.

"It was the one time you were really angry with me. I suppose now it went against something in the Mallansohn memoir."

"Not quite. It was just that the memoir did not speak of the kettles. It seemed to me that to avoid mention of such an outstanding aspect of Eternity meant he had little experience with it. It was my intention therefore to keep him away from the kettles as much as possible. The fact that you had taken him upwhen in one disturbed me greatly, but nothing happened afterward. Things continued as they should, so all is well."

The old Computer rubbed one hand slowly over the other, staring at the young Technician with a look compounded of surprise and curiosity. "And all along you"ve been guessing this. It simply astonishes me. I would have sworn that even a fully trained Computer could not have made the proper deductions, given only the information you had. For a Technician to do it is uncanny." He leaned forward, tapped Harlan"s knee lightly. "The Mallansohn memoir says nothing about your life after Cooper"s leaving, of course."

"I understand, sir," said Harlan.

"We will be free then, in a manner of speaking, to do as we please with it. You show a surprising talent that must not be wasted. I think you are meant for something more than a Technician. I promise nothing now, but I presume that you realize that Computership is a clistinct possibility."

It was easy for Harlan to keep his dark face expressionless. He had had years of practice for that.

He thought: An additional bribe.

But nothing must be left to conjecture. His guesses, wild and unsupported at the start, arrived at by a freak of insight in the course of a very unusual and stimulating night, had become reasonable as the result of directed library research. They had become certainties now that Twissell had told him the story. Yet in one way at least there had been a deviation. Cooper was Mallansohn.

That had simply improved his position, but, wrong in one respect, he might be wrong in another. He must leave nothing to chance, then. Have it out! Make certain!

He said levelly, almost casually, "The responsibility is great for me, also, now that I know the truth."

"Yes, indeed?"

"How fragile is the situation? Suppose something unexpected were to happen and I were to miss a day when I ought to have been teaching Cooper something vital."

"I don"t understand you."
