So, as the Renaissance receded, a few writers began trying to imagine the future. Besides Madden with his
Memoirs of the Twentieth Century
and Mercier with his dream of the year 2440, others attempted imaginative fiction about societies to come, which can, in hindsight, be called “futuristic,” though that word did not register in English until 1915. They were all defying Aristotle, who wrote, “Nobody can
narrate
what has not yet happened. If there is narration at all, it will be of past events, the recollection of which is to help the hearers to make better plans for the future.”

The first true futurist in Asimov’s sense of the word was Jules Verne. In the 1860s, as railroad trains chugged across the countryside and sailing ships gave way to steam, he imagined vessels traveling under the sea, across the skies, to the center of the earth, and to the moon. We would say he was a man ahead of his time—he had an awareness, a sensibility, suited to a later era. Edgar Allan Poe was ahead of his time. The Victorian mathematician Charles Babbage and his protégé Ada Lovelace, forerunners of modern computing, were ahead of their time. Jules Verne was so far ahead of his time that he could never even find a publisher for his most futuristic book,
Paris au XXe siècle,
a dystopia featuring gas-powered cars, “boulevards lit as brightly as by the sun,” and machine warfare. The manuscript, handwritten in a yellow notebook, turned up in 1989, when a locksmith cracked open a long-sealed family safe.

The next great futurist was Wells himself.

We are all futurists now.

Per the
Oxford English Dictionary.
One precursor, though: in 1866, an English travel writer concluding a railway journey through Transylvania mused in the
Cornhill Magazine,
“This charm of traveling would become perfect if we could travel in time as well as in space—…take a fortnight in the fifteenth century, or, still more pleasant, a leap into the twenty-first. It is possible to accomplish this object more or less in imagination.”

Of course the century was turning only per the Christian calendar, and even so, in 1800, the consensus was barely firm. France, still in the throes of its revolution, was running on a new calendar of its own,
le calendrier républicain français,
so it was the year 9. Or 10. This Republican year had a neat 360 days, organized into months with new names, from
vendémiaire
to
fructidor.
Napoleon dispensed with that shortly after being crowned emperor on 11
frimaire,
year 13.

Evidently it was not easy to translate.
Current Literature
magazine in New York reported in 1899, “The ‘Mercure de France’ is about to begin publishing a translation of Mr. Wells’
Time Machine.
The translator finds the title difficult to put into French.
‘Le Chronomoteur,’ ‘Le Chrono Mobile,’ ‘Quarante Siècles à l’heure,’
and
‘La Machine à Explorer le Temps’
are some of the suggestions….”

Jarry explains: “The Present is non-existent, a tiny fraction of a phenomenon, smaller than an atom. The physical size of an atom is known to be 1.5 x 10
–8
centimeters in diameter. No one has yet measured the fraction of a solar second that is equal to the Present.”

Philosophers and Pulps

“Time travel?! You expect me to believe such nonsense?”
“Yes, it is a difficult concept, isn’t it.”
—Douglas Adams (“The Pirate Planet,”
Doctor Who,
1978)

TIME TRAVEL AS DESCRIBED
by Wells and his many heirs is everywhere now, but it does not exist. It cannot. In saying so, it occurs to me that I’m Filby.

“But the thing’s a mere paradox,”
says the Editor.
“It’s against reason,”
says Filby.

Critics of the 1890s took the same view. Wells knew they would. When his book was finally published in the spring of 1895—
The Time Machine: An Invention,
sold in New York by Henry Holt (75¢) and in London by William Heinemann (2/6)—reviewers admired it for a good tale: a “fantastic story”; “shocker of no ordinary kind”; “
tour de force
of ghastly imaginings”; “distinctly above the average of such fanciful works”; and “worth reading if you like to read impossible yarns” (that last from the
New York Times
). They noted the apparent influence of the Dark Romantics, Edgar Allan Poe and Nathaniel Hawthorne. One sniffed, “We have some difficulty in discerning the exact utility of such excursions into futurity.”

Only a few paid Wells the compliment of analyzing his fantastic notion logically. They found it illogical. “There is no getting into the Future, except by waiting,” wrote Israel Zangwill in the
Pall Mall Magazine,
wagging a stern finger. “You can only sit down and see it come by.” Zangwill, himself an occasional novelist and humorist, soon also to be a famous Zionist, thought he understood time quite well. He admonished the author:

In verity there is no Time Traveller, Mr. Wells, save Old Father Time himself. Instead of being a Fourth Dimension of Space, Time is perpetually travelling through Space, repeating itself in vibrations farther and farther from the original point of incidence; a vocal panorama moving through the universe across the infinities, a succession of sounds and visions that, having once been, can never pass away…

(Zangwill had clearly been reading Poe: vibrations indefinitely extending through the atmosphere—“no thought can perish”—and this sentence, too, sails indefinitely onward.)

…but only on and on from point to point, permanently enregistered in the sum of things, preserved from annihilation by the endlessness of Space, and ever visible and audible to eye or ear that should travel in a parallel movement.

Despite his objections Zangwill couldn’t help but admire Wells’s “brilliant little romance.” He shrewdly noticed that
The Arabian Nights
had employed a sort of time-machine precursor: a magic carpet that traverses space. Meanwhile, even in 1895, Zangwill seemed to understand certain peculiar implications of time travel—the paradoxes, we will soon say—better than Wells himself.

The Time Machine
looks one way: forward. Ostensibly Wells’s time machine could travel to the past with a reverse throw of the lever, but the Time Traveller had no interest in going there. And a good thing too, says Zangwill. Just think what difficulties would be entailed. Our past had no Time Traveller barging through. A past that included a Time Traveller would be a different past, a new past. None of this was easy to put into words:

Had he travelled backwards, he would have reproduced a Past which, in so far as his own appearance in it with his newly invented machine was concerned, would have been
ex hypothesi
unveracious.

Then there’s the problem of meeting oneself. Zangwill becomes the first to notice this, and he will not be the last:

Had he recurred to his own earlier life, he would have had to exist in two forms simultaneously, of varying ages—a feat which even Sir Boyle Roche would have found difficult.

(His readers would recognize Roche as the Irish politician who said, “Mr. Speaker, it is impossible I could have been in two places at once, unless I were a bird.”)

The book reviewers came and went, and before long philosophers got into the game. When they first took notice of time travel it was with a certain embarrassment, like a symphony conductor unable to look away from an organ grinder. “A frivolous example drawn from contemporary fiction,” said Professor Walter Pitkin at Columbia University, writing in the
Journal of Philosophy
in 1914. Something was stirring in science—the realm in which time was a measurable and absolute quantity known familiarly as
t
—and philosophers were uneasy. In the first years of the new century, when they turned to the subject of time, they had one thinker above all to contend with: the young Frenchman Henri Bergson. In the United States, William James, who might otherwise have been resting on his laurels as the “father of psychology,” found new vitality in Bergson. “Reading his works is what has made me bold,” James said in 1909. “If I had not read Bergson, I should probably still be blackening endless pages of paper privately, in the hope of making ends meet that were never meant to meet.” (He added, “I have to confess that Bergson’s originality is so profuse that many of his ideas baffle me entirely.”)

Bergson asks us to remember how artificial is the notion of space as an empty homogenous medium—the absolute space announced by Newton. It is a creation of human intellect, he notes: “We may as well say that men have a special faculty of perceiving or conceiving a space without quality.” Scientists may find this abstract empty space to be useful for calculating, but let’s not make the mistake of confusing it with
reality.
Even more so with time. When we measure time with mechanical clocks, when we draw diagrams where time is an axis on a graph, we may fall into the trap of imagining time to be merely another version of space. To Bergson, time
t,
the time of the physicists, sliced into hours, minutes, and seconds, turned philosophy into a prison. He rejected the immutable, the absolute, the eternal. He embraced flux, process, becoming. For Bergson, the philosophical analysis of time could not be divorced from our human experience of it: the overlapping of mental states, the segue from one to the next that we experience as duration—
la durée.

He held time apart from space rather than commingling the two: “Time and space begin to interweave only when both become fictional.” He saw time, not space, as the essence of consciousness; duration, the heterogeneous tide of moments, as the key to freedom. Philosophers were about to follow physics down a new path, and Bergson would be left behind, but for now he was hugely popular. Crowds thronged his lectures at the Collège de France, Proust attended his wedding, and James called him a magician. “Dive back into the flux then,” cried James. “Turn your face toward sensation, that flesh-bound thing which rationalism has always loaded with abuse.” Here he parted company with physics.

What really
exists
is not things made but things in the making. Once made, they are dead….Philosophy should seek this kind of living understanding of the movement of reality, not follow science in vainly patching together fragments of its dead results.

Pitkin seems to have felt that he needed to rescue the poor scientists from Bergson’s onslaught. Described by
Time
magazine in a brief moment of fame as “a man of many ideas, some of them large,” he was a founding member of a short-lived movement that called itself new realism. In his 1914 essay he declared that he liked some of Bergson’s “conclusions” but despised his “entire method,” particularly the rejection of scientific process in favor of psychological introspection. Pitkin proposed to clear up the space-time conundrum by means of logical proof. He would embrace the physicists’
t
and
t
′ and
t
′′ and yet he would prove once and for all that time is different from space. To wit: we can move hither and yon in space, but not in time. Or rather, we do move in time, but not freely: “a thing moves in time only by moving with all other things.” And how would he prove this? In a most unexpected way:

To make the proof as simple as possible, I shall present it in the form of a sober criticism of one of the wildest flights of literary fancy which that specialist in wild flights, H. G. Wells, has indulged in. I refer, of course, to his amusing skit,
The Time Machine.

It was the first but not the last time that Mr. Wells’s amusing skit would impose itself upon the attention of this august journal.

“You cannot leap back into the thirteenth century, nor can a man of that period hop into our own,” wrote Pitkin. “Mr. Wells would have us imagine a man at rest in the space dimensions, but moving with respect to the time of that space field. Very well! Let us do our noblest to play the game. What do we find? Something very disconcerting indeed. Something which, I fear, will make time-touring very unpopular among sedate people.”

The traveler flies, not through abstract time (like the “pure space” of the geometer).
He flies through real time. But real time is history: and history is the course of physical events. It is the sequence of activities, physical, physiological, political, and otherwise.

Do we really want to go down this road? Must we look for errors of logic in a piece of fantastic fiction?

Yes, we must. The practitioners of time travel, even in “pulp” magazines, were soon to work out rules and justifications that would make a Talmudist proud. What is allowed, what is possible, what is plausible—the rules evolved and varied, but logic must be honored. We may as well begin with Professor Pitkin, man of many ideas, some of them large, in the
Journal of Philosophy.
