Time Travel
Stephen Dedalus says memorably in Ulysses that history is a nightmare from which he is trying to awake. Is there no escape? What if Julius Caesar had not been murdered on the Senate steps, or Pyrrhus killed in Argos? “Time has branded them,” thinks Stephen, “and fettered they are lodged in the room of the infinite possibilities they have ousted. But can those have been possible seeing that they never were? Or was that only possible which came to pass? Weave, weaver of the wind.”
Can these eager assassins change history or can’t they? For a while, every new story seemed to offer a new theory. Alfred Bester, a New York PR man turned sci-fi writer, invented his own special variation of you can’t change history for his 1958 story, “The Men Who Murdered Mohammed.” The unhappy protagonist, Henry Hassel, angered by discovering his wife “in the arms of” another man, goes on an ever-more-murderous rampage through history, armed with his time machine and a .45-caliber pistol, killing parents and grandparents and historical figures near and far, Columbus, Napoleon, Mohammed (everyone but Hitler), and nothing seems to work. The wife continues in her merry ways. Why? Another sad time traveler finally explains:
“My boy, time is entirely subjective. It’s a private matter….We each travel into our own past, and no other person’s. There is no universal continuum, Henry. There are only billions of individuals, each with his own continuum; and one continuum cannot affect the other. We’re like millions of strands of spaghetti in the same pot….Each of us must travel up and down his strand alone.”
From branching paths to spaghetti strands.
In Stephen Fry’s variation, the hero is a student historian named Michael Young. (One wonders—why do our imaginative time-travel writers keep naming their characters Young?) In this variation, he hopes to change history not by assassinating Hitler but by sterilizing his father: “The historian as God. I know so much about you, Mr. So-Called Hitler, that I can stop you from being born.” And then? Will the twentieth century live happily ever after? (“It was insane of course. I knew that. It couldn’t possibly work. You can’t change the past. You can’t redesign the present.”) All you can do is ask, What if? The novelist makes the world. Kate Atkinson’s 2013 novel, Life After Life, changes the rules yet again. The shooting of Hitler comes in the opening scene: our heroine, Ursula Todd (surname death this time) fires her father’s old service revolver at the Führer across the table in a Munich café in 1930. Then she dies, and she keeps on dying, again and again, at different ages, in different ways, always starting over and trying to do it right. Her alternative lives are like strands of spaghetti in a pot. “History is all about ‘what ifs,’ ” someone tells her, as if she didn’t know. Someone else urges, “We must bear witness…we must remember these people when we are safely in the future.” Atkinson, the author, said later, “I am in that future now, and I suppose this book is my bearing witness to the past.”
One consequence of Hitler’s being the favorite victim of time-traveling assassins is that he keeps on coming back to life. Here he is, living in the Amazon jungle, ninety years old, in George Steiner’s novel The Portage to San Cristóbal of A.H. Or alive and well in Berlin, still führer of the Greater German Reich, having won World War II in Robert Harris’s Fatherland. Or syphilitic and senile, in The Man in the High Castle by Philip K. Dick—Germany has won the war, because in this history it was the young Franklin D. Roosevelt who was assassinated before he could put his strong hand on the tiller of history. The variations on this theme continue to multiply. As a literary genre, these counterfactual narratives are called alternative history in English, or ucronía, uchronie, etc., or allohistory. The labels arose only in the mid to late twentieth century, when the genre began to explode, fed by time travel and branching universes, but in 1930 James Thurber was presciently satirizing it in the New Yorker magazine, in his story “If Grant Had Been Drinking at Appomattox” (identified as a follow-up to “If Booth Had Missed Lincoln,” “If Lee Had Won the Battle of Gettysburg,” and “If Napoleon Had Escaped to America”). Professionals ask similar questions these days. The humor bleeds into academic historiography. It’s possible to become quite obsessed with historical contingency. In a comprehensive study, The World Hitler Never Made, Gavriel D. Rosenfeld analyzed as many of the Nazi variations as he could find to see how many ended up making history “the same or worse without Hitler as opposed to being better.”*6 There are few happy endings, he found. It is often the writers of science fiction or “speculative fiction” who give us, not only the weirdest, but the most rigorously analyzed approaches to the working of history.
It all might have been different. For want of a nail, the kingdom was lost. I coulda been a contender. Regret is the time traveler’s energy bar. If only…something. Every writer nowadays knows about the butterfly effect. The slightest flutter might alter the course of great events. A decade before the meteorologist and chaos theorist Edward Lorenz chose the butterfly for illustrative purposes, Ray Bradbury deployed a history-changing butterfly in his 1952 story “A Sound of Thunder.” Here the time machine—the Machine, a vague mess of “silver metal” and “roaring light”—carries paying sightseers on Time Safaris back to the era of the dinosaurs. Apart from the addition of oxygen helmets and intercoms, the time travel itself is pure Wells: “The Machine howled. Time was a film run backward. Suns fled and ten million moons fled after them….The Machine slowed; its scream fell to a murmur.” The Safari operators, though, try to be careful about leaving everything unchanged, because they worry about history.
A little error here would multiply in sixty million years, all out of proportion….A dead mouse here makes an insect imbalance there, a population disproportion later, a bad harvest further on, a depression, mass starvation….Perhaps only a soft break, a whisper, a hair, pollen on the air, such a slight, slight change that unless you looked close you wouldn’t see it. Who knows?
In the event, a feckless time-tourist steps on a butterfly: “an exquisite thing, a small thing that could upset balances and knock down a line of small dominoes and then big dominoes and then gigantic dominoes, all down the years across Time.”
The butterfly effect, though, is a matter of potential only. Not every flutter in the air leaves its mark on the ages. Most fade to nothing, damped by viscosity. That was Asimov’s assumption in The End of Eternity: that the effects of tampering with history tend to die out as the centuries pass, perturbations extinguished by friction or dissipation. His Technician confidently explains: “Reality has a tendency to flow back to its original position.” But Bradbury was right and Asimov was wrong. If history is a dynamical system, it’s surely nonlinear, and the butterfly effect must obtain. At some places, some times, a slight divergence can transform history. There are critical moments—nodal points. These are where you want to place your lever. History—our real history, that is—must be full of such moments or people, if only we could identify them. We imagine that we can. Births and assassinations, military victories and defeats. We focus on individuals, heroes and villains with an outsize influence. Hence the fascination with Hitler. If you could kill just one person…By and large, though, the creators of these fantasies have been wise enough to mock the hubris they imply. “Can anyone alter fate?” asks Philip K. Dick in The Man in the High Castle. “All of us combined…or one great figure…or someone strategically placed, who happens to be in the right spot. Chance. Accident. And our lives, our world, hanging on it.” Surely some people, some events, some decisions matter more than others. Nodal points must exist, just not necessarily where we think.
Stuck as we are in our own time, most of us aren’t trying to make history, much less change it. We take the days one at a time, and history happens. Clive James has said that the greatest poets aspire not to change literary history but only to enrich it. One more reason for the special fascination with Hitler is his playing God. “The Führer was different,” thinks Kate Atkinson’s Ursula Todd, “he was consciously making history for the future. Only a true narcissist could do tha
t.” Beware the politician who aspires to make history. Ursula herself lives in her many moments, one timeline after another: “the future as much a mystery as the past.”
We cannot escape the alternative realities, the limitless variations. The OED carefully tells us that the word multiverse was “orig. Science Fiction” but now, alas, “Physics”: “the large collection of universes in the many-worlds interpretation of quantum mechanics…in which each in turn of the different possible outcomes occurs.” At the same time, entirely apart from quantum theory, we have discovered the pleasure and pain of virtual worlds, inside the computer or the matrix, forcing us to contemplate the possibility that we ourselves are characters in someone else’s simulated reality. Or our own. Nowadays, when one speaks of “the real world,” it is difficult to refrain from using ironic quotation marks. We inhabit virtual worlds as familiarly and as avidly as the real one. In virtual worlds time travel could not be easier.
Follow me down the rabbit hole into the looping tunnels. William Gibson will be our Virgil. He is reading The Alteration, a 1976 novel of alternative history by Kingsley Amis, better known for his comic satires of contemporary Britain. In this world Europe has succumbed to authoritarianism, but never mind Hitler—the papacy is in charge. The Reformation never happened, and the Catholic Church holds much of the world in a theocratic grip. Amis is, of course, investigating in a sidelong way his own, all-too-real world, just as Philip Roth is in The Plot Against America and Fry in Making History. Amis’s story opens in the Cathedral Basilica of St. George at Coverley, “the mother church of all England and of the English Empire overseas.” In passing we observe bits of perverted art history: Turner has evidently painted the ceiling “in commemoration of the Holy Victory,” Blake has decorated one wall with some holy frescoes, and the choir sings Mozart’s Second Requiem, “the crown of his middle age.” Science has been suppressed. Although it is 1976, there are wagons and oil lamps, but “matters electrical were held in general disesteem.” And there are wheels within wheels.
Lacking science, literature in the world of The Alteration has failed to generate science fiction, but the novel’s young hero enjoys reading in a disreputable genre known as Time Romance, or TR, for short. TR “appealed to a type of mind.” It was illegal but impossible to suppress fully. Inside this genre has evolved a subgenre known as Counterfeit World, CW. In this subgenre, books imagine histories that never happened—alternative histories. Now Gibson will explain:
Amis accomplishes, as it were in the attic of his novel, a sublime hall-of-mirrors effect. In our world, Philip K. Dick wrote The Man in the High Castle, in which the Axis triumphed in World War II. Within Dick’s book there is another, imaginary book, The Grasshopper Lies Heavy, envisioning a world in which the Allies won, though that world clearly isn’t ours. In Amis’s counterfeit world, someone called Philip K. Dick has written a novel, The Man in the High Castle, imagining a non-Catholic world. Which isn’t ours.
And isn’t theirs. It’s hard to keep track. Amis’s boy hero, in his world without science, is amazed to read of a counterfactual world where “they use electricity…they send messages all over the Earth with it” and Mozart died in 1799 and Beethoven wrote twenty symphonies, and another famous book explains that humans evolved from a thing like an ape. “This business of TR and CW strikes me,” says Gibson, “as it plays so artfully through the book, as likely the best Jorge Luis Borges story Jorge Luis Borges never wrote.”
The shelves continue to fill with counterfeit worlds. The future becomes the present, and so every futuristic fantasy is slated to become alternative history. When the year 1984 arrived, Orwell’s particular surveillance state made the transition from TR to CW. Then 2001 came and went without any noticeable space odysseys. The careful futurist learns to avoid specifying dates. Still our literature and our filmmaking keep breeding new pasts, along with all the putative futures. And so do we all, every day, every night, waking and dreaming in the subjunctive, weighing the options, regretting the might-have-beens.

“DUAL TIME-TRACKS, alternate universes,” scoffs a skeptical lawyer in Ursula K. Le Guin’s 1971 novel The Lathe of Heaven. “Do you see a lot of old late-night TV shows?”
Her troubled client is a man named George Orr. (A tip of the hat to George Orwell, whose special year, 1984, had nearly arrived when Le Guin, in her forties, departed from her previous form to write this strange book.*7) When aliens appear, they pronounce his name Jor Jor.
He is an ordinary man—an office worker, apparently placid, milquetoast, conventional. But George is a dreamer. When he was sixteen, he dreamed that his aunt Ethel had been killed in a car crash, and when he awoke he realized that his aunt Ethel had been killed in a car crash, weeks earlier. His dream changed reality retroactively. He has “effective dreams”—a sci-fi trope invented here. You might say he carries alternate universes within. Who else does that? The author, for one.
This is a lot of responsibility, and George doesn’t want it. He has no more control over his dreams than you or I—not conscious control, anyway. (He fears he had resented Ethel’s sexual advances.) Increasingly desperate, he doses himself with barbiturates and dextroamphetamine in hopes of suppressing his dreams altogether and ends up in the hands of a psychologist—a dreaming specialist—named William Haber. Haber believes in striving and control; he believes in the power of reason and science. He is plasticoated, like his office furniture. He hypnotizes poor George in an effort to guide his effective dreams and remake reality, step by step. The doctor’s office decor seems to have improved. Somehow he has become Director of the Institute.
For the rest of the universe, pulled in the wake of George’s dreams, progress is not so simple. Just as quantum theorists may have trouble finding sensible pathways through an unconstrained cornucopia of universes, so might the conscientious novelist. Le Guin does not make matters easy for the reader. She draws us no diagrams.*8 We must drift in her currents and listen carefully. The music changes. The weather changes. Portland is a city of ceaseless rain, “a downpour of warm soup, forever.” Portland enjoys clear air and level sunlight. Was there a dream about President John F. Kennedy and an umbrella? Dr. Haber encourages George to focus on his dread of overpopulation—Portland is a crowded metropolis of three million souls. Or Portland’s population has fallen to a hundred thousand, since the Plague Years and the Crash. Everyone remembers those: pollutants in the atmosphere “combining to form virulent carcinogens,” the first epidemic, “the riots, and the fuck-ins, and the Doomsday Band, and the Vigilantes.” Only George and now Dr. Haber remember multiple realities. “They took care of the overpopulation problem, didn’t they?” George says sarcastically. “We really did it.” When are we less the masters of our thoughts than when we dream?
He is not a time traveler. He does not travel through time. He changes it: the past and the future, at once. Much later, sci-fi developed terminology for these conventions, or borrowed them from physics: alternative histories may be called “timelines” or, per William Gibson, “stubs.” In any one stub, people are bound to think that their history is the only one that happened. It’s not so much that Orr’s dream brings a new plague; it’s that once he has dreamed, the plague had always happened. He begins to appreciate the paradox. “He thought: In that life, yesterday, I dreamed an effective dream, which obliterated six billion lives and changed the entire history of humankind for the past quarter century. But in this life, which I then created, I did not dream an effective dream.” There was always a plague. If this sounds like George Orwell’s “We’ve always been at war with Eastasia,” that’s no accident. Totalitarian governments also purvey alternate histories.*9
The Lathe of Heaven is a critique of a certain kind of hubris—one that every willful creature shares in some degree. It is the hubris of politicians and social engineers: champions of progress who believe we can remake the world. “Isn’t that man’s very purpose on earth—to do things, change things, run things, make a better wo
rld?” says Haber, the scientist, when Orr expresses doubts. Change is good: “Nothing remains the same from one moment to the next, you can’t step into the same river twice.”
George sees it differently. “We’re in the world, not against it,” he says. “It doesn’t work to try to stand outside things and run them that way. It just doesn’t work, it goes against life.” Evidently he is a natural Taoist. “There is a way but you have to follow it. The world is, no matter how we think it ought to be.”
Having solved overpopulation, Haber tries to use George to bring about peace on Earth. What could go wrong? The Alien Invasion. Sirens, crashes, silvery spaceships. The eruption of Mount Hood. Orr dreams an end to racial strife, to “color problems.” Now everyone is gray.
A word from Zhuang Zhou: “Those who dream of feasting wake to lamentation.”
It seems there is no way out of this mess—no way based on intention or control—but an unexpected source of wisdom appears: the Aliens. They look like big green turtles. They sense a kindred spirit in Jor Jor, as well they might, since he has presumably dreamed them into existence. They speak in riddles:
We also have been variously disturbed. Concepts cross in mist. Perception is difficult. Volcanoes emit fire. Help is offered: refusably. Snakebite serum is not prescribed for all. Before following directions leading in wrong directions, auxiliary forces may be summoned.
They sound vaguely Taoist themselves. “Self is universe. Please forgive interruption, crossing in mist.”
