“I can’t recall the exact manner in which I blundered into it. The fact that I did make such a blunder was because I was talking extemporaneously and had wandered ahead of my text. I was trying to show the results of the collapse of the Ottoman Empire after the First World War, and the partition of the Middle East into a loose collection of Arab states, and the passing of British and other European spheres of influence following the Second. You know, when you consider it, the Islamic Caliphate was inevitable; the surprising thing is that it was created by a man like Khalid . . .”
He was talking to gain time, and he suspected that Hauserman knew it. The “memories” were coming into his mind more and more strongly; it was impossible to suppress them. The period of anarchy following Khalid’s death would be much briefer, and much more violent, than he had previously thought. Tallal ib’n Khalid would be flying from England even now; perhaps he had already left the plane to take refuge among the black tents of his father’s Bedouins. The revolt at Damascus would break out before the end of the month; before the end of the year, the whole of Syria and Lebanon would be in bloody chaos, and the Turkish army would be on the march.
“Yes. And you allowed yourself to be carried a little beyond the present moment, into the future, without realizing it? Is that it?”
“Something like that,” he replied, wide awake to the trap Hauserman had set, and fearful that it might be a blind, to disguise the real trap. “History follows certain patterns. I’m not a Toynbean, by any manner of means, but any historian can see that certain forces generally tend to produce similar effects. For instance, space travel is now a fact; our government has at present a military base on Luna. Within our lifetimes—certainly within the lifetimes of my students—there will be explorations and attempts at colonization on Mars and Venus. You believe that, Doctor?”
“Oh, unreservedly. I’m not supposed to talk about it, but I did some work on the Philadelphia Project, myself. I’d say that every major problem of interplanetary flight had been solved before the first robot rocket was landed on Luna.”
“Yes. And when Mars and Venus are colonized, there will be the same historic situations, at least in general shape, as arose when the European powers were colonizing the New World, or, for that matter, when the Greek city-states were throwing out colonies across the Aegean. That’s the sort of thing we call projecting the past into the future through the present.”
Hauserman nodded. “But how about the details? Things like the assassination of a specific personage. How can you extrapolate to a thing like that?”
“Well . . .” More “memories” were coming to the surface; he tried to crowd them back. “I do my projecting in what you might call fictionalized form; try to fill in the details from imagination. In the case of Khalid, I was trying to imagine what would happen if his influence were suddenly removed from Near Eastern and Middle Eastern, affairs. I suppose I constructed an imaginary scene of his assassination . . .”
He went on at length. Mohammed and Noureed were common enough names. The Middle East was full of old U.S. weapons. Stoning was the traditional method of execution; it diffused responsibility so that no individual could be singled out for blood-feud vengeance.
“You have no idea how disturbed I was when the whole thing happened, exactly as I had described it,” he continued. “And worst of all, to me, was this Intelligence officer showing up; I thought I was really in for it!”
“Then you’ve never really believed that you had real knowledge of the future?”
“I’m beginning to, since I’ve been talking to these Psionics and Parapsychology people,” he laughed. It sounded, he hoped, like a natural and unaffected laugh. “They seem to be convinced that I have.”
There would be an Eastern-inspired uprising in Azerbaijan by the middle of the next year; before autumn, the Indian Communists would make their fatal attempt to seize East Pakistan. The Thirty Days’ War would be the immediate result. By that time, the Lunar Base would be completed and ready; the enemy missiles would be aimed primarily at the rocketports from which it was supplied. Delivered without warning, it should have succeeded—except that every rocketport had its secret duplicate and triplicate. That was Operation Triple Cross; no wonder Major Cutler had been so startled at the words, last evening. The enemy would be utterly overwhelmed under the rain of missiles from across space, but until the moon-rockets began to fall, the United States would suffer grievously.
“Honestly, though, I feel sorry for my friend Fitch,” he added. “He’s going to be frightfully let down when some more of my alleged prophecies misfire on him. But I really haven’t been deliberately deceiving him.”
And Blanley College was at the center of one of the areas which would receive the worst of the thermonuclear hell to come. And it would be a little under a year . . .
“And that’s all there is to it!” Hauserman exclaimed, annoyance in his voice. “I’m amazed that this man Whitburn allowed a thing like this to assume the proportions it did. I must say that I seem to have gotten the story about this business in a very garbled form indeed.” He laughed shortly. “I came here convinced that you were mentally unbalanced. I hope you won’t take that the wrong way, Professor,” he hastened to add. “In my profession, anything can be expected. A good psychiatrist can never afford to forget how sharp and fine is the knife-edge.”
“The knife-edge!” The words startled him. He had been thinking, at that moment, of the knife-edge, slicing moment after moment relentlessly away from the future, into the past, at each slice coming closer and closer to the moment when the missiles of the Eastern Axis would fall. “I didn’t know they still resorted to surgery, in mental cases,” he added, trying to cover his break.
“Oh, no; all that sort of thing is as irrevocably discarded as the whips and shackles of Bedlam. I meant another kind of knife-edge; the thin, almost invisible, line which separates sanity from non-sanity. From madness, to use a deplorable lay expression.” Hauserman lit another cigarette. “Most minds are a lot closer to it than their owners suspect, too. In fact, Professor, I was so convinced that yours had passed over it that I brought with me a commitment form, made out all but my signature, for you.” He took it from his pocket and laid it on the desk. “The modern equivalent of the lettre-de-cachet, I suppose the author of a book on the French Revolution would call it. I was all ready to certify you as mentally unsound, and commit you to Northern State Mental Hospital.”
Chalmers sat erect in his chair. He knew where that was; on the other side of the mountains, in the one part of the state completely untouched by the H-bombs of the Thirty Days’ War. Why, the town outside which the hospital stood had been a military headquarters during the period immediately after the bombings, and the center from which all the rescue work in the state had been directed.
“And you thought you could commit me to Northern State!” he demanded, laughing scornfully, and this time he didn’t try to make the laugh sound natural and unaffected. “You—confine me, anywhere? Confine a poor old history professor’s body, yes, but that isn’t me. I’m universal; I exist in all space-time. When this old body I’m wearing now was writing that book on the French Revolution, I was in Paris, watching it happen, from the fall of the Bastile to the Ninth Thermidor. I was in Basra, and saw that crazed tool of the Axis shoot down Khalid ib’n Hussein—and the professor talked about it a month before it happened. I have seen empires rise and stretch from star to star across the Galaxy, and crumble and fall. I have seen . . .”
Doctor Hauserman had gotten his pen out of his pocket and was signing the commitment form with one hand; with the other, he pressed a button on the desk. A door at the rear opened, and a large young man in a white jacket entered.
“You’ll have to go away for a while, Professor,” Hauserman was telling him, much later, after he had allowed himself to become calm again. “For how long, I don’t know. Maybe a year or so.”
“You mean to Northern State Mental?”
“Well . . . Yes, Professor. You’ve had a bad crack-up. I don’t suppose you realize how bad. You’ve been working too hard; harder than your nervous system could stand. It’s been too much for you.”
“You mean, I’m nuts?”
“Please, Professor. I deplore that sort of terminology. You’ve had a severe psychological breakdown . . .”
“Will I be able to have books, and papers, and work a little? I couldn’t bear the prospect of complete idleness.”
“That would be all right, if you didn’t work too hard.”
“And could I say good-bye to some of my friends?”
Hauserman nodded and asked, “Who?”
“Well, Professor Pottgeiter . . .”
“He’s outside now. He was inquiring about you.”
“And Stanly Weill, my attorney. Not business; just to say good-bye.”
“Oh, I’m sorry, Professor. He’s not in town, now. He left almost immediately after . . . After . . .”
“After he found out I was crazy for sure? Where’d he go?”
“To Reno; he took the plane at five o’clock.”
Weill wouldn’t have believed, anyhow; no use trying to blame himself for that. But he was as sure that he would never see Stanly Weill alive again as he was that the next morning the sun would rise. He nodded impassively.
“Sorry he couldn’t stay. Can I see Max Pottgeiter alone?”
“Yes, of course, Professor.”
Old Pottgeiter came in, his face anguished. “Ed! It isn’t true,” he stammered. “I won’t believe that it’s true.”
“What, Max?”
“That you’re crazy. Nobody can make me believe that.”
He put his hand on the old man’s shoulder. “Confidentially, Max, neither do I. But don’t tell anybody I’m not. It’s a secret.”
Pottgeiter looked troubled. For a moment, he seemed to be wondering if he mightn’t be wrong and Hauserman and Whitburn and the others right.
“Max, do you believe in me?” he asked. “Do you believe that I knew about Khalid’s assassination a month before it happened?”
“It’s a horribly hard thing to believe,” Pottgeiter admitted. “But, dammit, Ed, you did! I know, medieval history is full of stories about prophecies being fulfilled. I always thought those stories were just legends that grew up after the event. And, of course, he’s about a century late for me, but there was Nostradamus. Maybe those old prophecies weren’t just ex post facto legends, after all. Yes. After Khalid, I’ll believe that.”
“All right. I’m saying, now, that in a few days there’ll be a bad explosion at Reno, Nevada. Watch the papers and the telecast for it. If it happens, that ought to prove it. And you remember what I told you about the Turks annexing Syria and Lebanon?” The old man nodded. “When that happens, get away from Blanley. Come up to the town where Northern State Mental Hospital is, and get yourself a place to live, and stay there. And try to bring Marjorie Fenner along with you. Will you do that, Max?”
“If you say so.” His eyes widened. “Something bad’s going to happen here?”
“Yes, Max. Something very bad. You promise me you will?”
“Of course, Ed. You know, you’re the only friend I have around here. You and Marjorie. I’ll come, and bring her along.”
“Here’s the key to my apartment.” He got it from his pocket and gave it to Pottgeiter, with instructions. “Everything in the filing cabinet on the left of my desk. And don’t let anybody else see any of it. Keep it safe for me.”
The large young man in the white coat entered.
BLANK!

Time travel involved no paradoxes at all: the machine was as safe as an elevator!
“PRESUMABLY,” said August Pointdexter, “there is such a thing as overweening pride. The Greeks called it hubris, and considered it to be defiance of the gods, to be followed always by ate, or retribution.” He rubbed his pale blue eyes uneasily.
“Very pretty,” said Dr. Edward Barron impatiently. “Has that any connection with what I said?” His forehead was high and had horizontal creases in it that cut in sharply when he raised his eyebrows in contempt.
“Every connection,” said Pointdexter. “To construct a time machine is itself a challenge to fate. You make it worse by your flat confidence. How can you be sure that your time-travel machine will operate through all of time without the possibility of paradox?”
Barron said, “I didn’t know you were superstitious. The simple fact is that a time machine is a machine like any other machine, no more and no less sacrilegious. Mathematically, it is analogous to an elevator moving up and down its shaft. What danger of retribution lies in that?”
Pointdexter said energetically, “An elevator doesn’t involve paradoxes. You can’t move from the fifth floor to the fourth and kill your grandfather as a child.”
Dr. Barron shook his head in agonized impatience. “I was waiting for that. For exactly that. Why couldn’t you suggest that I would meet myself or that I would change history by telling McClellan that Stonewall Jackson was going to make a flank march on Washington, or anything else? Now I’m asking you point blank. Will you come into the machine with me?”
Pointdexter hesitated. “I . . . I don’t think so.”
“Why do you make things difficult? I’ve explained already that time is invariant. If I go into the past it will be because I’ve already been there. Anything I decided to do and proceed to do. I will have already done in the past all along, so I’ll be changing nothing and no paradoxes will result. If I decided to kill my grandfather as a baby, and did it I would not be here. But I am here. Therefore I did not kill my grandfather. No matter how I try to kill him and plan to kill him, the fact is I didn’t kill him and so I won’t kill him. Nothing would change that. Do you understand what I’m explaining?”
“I understand what you say, but are you right?”
“Of course I’m right. For God’s sake, why couldn’t you have been a mathematician instead of a machinist with a college education?” In his impatience, Barron could scarcely hide his contempt. “Look, this machine is only possible because certain mathematical relationships between space and time hold true. You understand that, don’t you, even if you don’t follow the details of the mathematics? The machine exists, so the mathematical relations I worked out have some correspondence in reality. Right? You’ve seen me send rabbits a week into the future. You’ve seen them appear out of nothing. You’ve watched me send a rabbit a week into the past one week after it appeared. And they were unharmed.”
“All right. I admit all that.”
“Then will you believe me if I tell you that the equations upon which this machine is based assume that time is composed of particles that exist in an unchanging order; that time is invariant. If the order of the particles could be changed in any way-any way at all-the equations would be invalid and this machine wouldn’t work; this particular method of time travel would be impossible.”
Pointdexter rubbed his eyes again and looked thoughtful. “I wish I knew mathematics.”
Barron said, “Just consider the facts. You tried to send the rabbit two weeks into the past when it had arrived only one week in the past. That would have created a paradox, wouldn’t it? But what happened? The indicator stuck at one week and wouldn’t budge. You couldn’t create a paradox. Will you come?”
Pointdexter shuddered at the edge of the abyss of agreement and drew back. He said, “No.”
Barron said, “I wouldn’t .ask you to help if I could do this alone, but you know it takes two men to operate the machine for intervals of more than a month. I need someone to control the Standards so that we can return with precision. And you’re the one I want to use. We share the-the glory of this thing now. Do you want to thin it out, but in a third person? Time enough for that after we’ve established ourselves as the first time travelers in history. Good Lord, man, don’t you want to see where we’ll be a hundred years from now, or a thousand; don’t you want to see Napoleon, or Jesus, for that matter? We’ll be like—like”—Barron seemed carried away—“like gods.”
“Exactly,” mumbled Pointdexter. “Hubris. Time travel isn’t godlike enough to risk being stranded out of my own time.”
“Hubris. Stranded. You keep making up fears. We’re just moving along the particles of time like an elevator along the floors of a building. Time travel is actually safer because an elevator cable can break, whereas in the time machine there’ll be no gravity to pun us down destructively. Nothing wrong can possibly happen. I guarantee it,” said Barron, tapping his chest with the middle finger of his right hand. “I guarantee it.”
“Hubris,” muttered Pointdexter, but fell into the abyss of agreement nevertheless, overborne at last.
Together they entered the machine.
“POINTDEXTER did not understand the controls in the sense Barron did, for he was no mathematician, but he knew how they were supposed to be handled.
Barron was at one set, the Propulsions. They supplied the drive that forced the machine along the time axis. Pointdexter was at the Standards that kept the point of origin fixed so that the machine could move back to the original starting point at any time.
Pointdexter’s teeth chattered as the first motion made itself felt in his stomach, Like an elevator’s motion it was, but not quite, It was something more subtle, yet very real. He said, “What if—”
Barron snapped out, “Nothing can go wrong. Please!” And at once there was a jar and Pointdexter fell heavily against the wall.
Barron said, “What the devil!”
“What happened?” demanded Pointdexter breathlessly. “I don’t know, but it doesn’t matter. We’re only twenty-two hours into the future. Let’s step out and check.”
The door of the machine slid into its recessed panel and the breath went out of Pointdexter’s body in a panting whoosh. He said, “There’s nothing there.”
Nothing. No matter. No light. Blank!
Pointdexter screamed. “The Earth moved. We forgot that. In twenty-two hours, it moved thousands of miles through space, traveling around the sun.”
