<h2><SPAN name="chap01"></SPAN>I.<br/> Introduction</h2>
<p>The Time Traveller (for so it will be convenient to speak of him) was
expounding a recondite matter to us. His pale grey eyes shone and twinkled, and
his usually pale face was flushed and animated. The fire burnt brightly,
and the soft radiance of the incandescent lights in the lilies of silver
caught the bubbles that flashed and passed in our glasses. Our chairs,
being his patents, embraced and caressed us rather than submitted to be sat
upon, and there was that luxurious after-dinner atmosphere, when thought
runs gracefully free of the trammels of precision. And he put it to us in
this way—marking the points with a lean forefinger—as we sat
and lazily admired his earnestness over this new paradox (as we thought it)
and his fecundity.</p>
<p>“You must follow me carefully. I shall have to controvert one or
two ideas that are almost universally accepted. The geometry, for instance,
they taught you at school is founded on a misconception.”</p>
<p>“Is not that rather a large thing to expect us to begin
upon?” said Filby, an argumentative person with red hair.</p>
<p>“I do not mean to ask you to accept anything without reasonable
ground for it. You will soon admit as much as I need from you. You know of
course that a mathematical line, a line of thickness <i>nil</i>, has no
real existence. They taught you that? Neither has a mathematical plane.
These things are mere abstractions.”</p>
<p>“That is all right,” said the Psychologist.</p>
<p>“Nor, having only length, breadth, and thickness, can a cube have
a real existence.”</p>
<p>“There I object,” said Filby. “Of course a solid body
may exist. All real things—”</p>
<p>“So most people think. But wait a moment. Can an
<i>instantaneous</i> cube exist?”</p>
<p>“Don’t follow you,” said Filby.</p>
<p>“Can a cube that does not last for any time at all, have a real
existence?”</p>
<p>Filby became pensive. “Clearly,” the Time Traveller
proceeded, “any real body must have extension in <i>four</i>
directions: it must have Length, Breadth, Thickness, and—Duration.
But through a natural infirmity of the flesh, which I will explain to you
in a moment, we incline to overlook this fact. There are really four
dimensions, three which we call the three planes of Space, and a fourth,
Time. There is, however, a tendency to draw an unreal distinction between
the former three dimensions and the latter, because it happens that our
consciousness moves intermittently in one direction along the latter from
the beginning to the end of our lives.”</p>
<p>“That,” said a very young man, making spasmodic efforts to
relight his cigar over the lamp; “that . . . very clear
indeed.”</p>
<p>“Now, it is very remarkable that this is so extensively
overlooked,” continued the Time Traveller, with a slight accession of
cheerfulness. “Really this is what is meant by the Fourth Dimension,
though some people who talk about the Fourth Dimension do not know they
mean it. It is only another way of looking at Time. <i>There is no
difference between Time and any of the three dimensions of Space except
that our consciousness moves along it</i>. But some foolish people have got
hold of the wrong side of that idea. You have all heard what they have to
say about this Fourth Dimension?”</p>
<p>“<i>I</i> have not,” said the Provincial Mayor.</p>
<p>“It is simply this. That Space, as our mathematicians have it, is
spoken of as having three dimensions, which one may call Length, Breadth,
and Thickness, and is always definable by reference to three planes, each
at right angles to the others. But some philosophical people have been
asking why <i>three</i> dimensions particularly—why not another
direction at right angles to the other three?—and have even tried to
construct a Four-Dimensional geometry. Professor Simon Newcomb was expounding
this to the New York Mathematical Society only a month or so ago. You know
how on a flat surface, which has only two dimensions, we can represent a
figure of a three-dimensional solid, and similarly they think that by
models of three dimensions they could represent one of four—if they
could master the perspective of the thing. See?”</p>
<p>“I think so,” murmured the Provincial Mayor; and, knitting
his brows, he lapsed into an introspective state, his lips moving as one
who repeats mystic words. “Yes, I think I see it now,” he said
after some time, brightening in a quite transitory manner.</p>
<p>“Well, I do not mind telling you I have been at work upon this
geometry of Four Dimensions for some time. Some of my results are curious.
For instance, here is a portrait of a man at eight years old, another at
fifteen, another at seventeen, another at twenty-three, and so on. All
these are evidently sections, as it were, Three-Dimensional representations
of his Four-Dimensioned being, which is a fixed and unalterable thing.</p>
<p>“Scientific people,” proceeded the Time Traveller, after the
pause required for the proper assimilation of this, “know very well
that Time is only a kind of Space. Here is a popular scientific diagram, a
weather record. This line I trace with my finger shows the movement of the
barometer. Yesterday it was so high, yesterday night it fell, then this
morning it rose again, and so gently upward to here. Surely the mercury did
not trace this line in any of the dimensions of Space generally recognised?
But certainly it traced such a line, and that line, therefore, we must
conclude, was along the Time-Dimension.”</p>
<p>“But,” said the Medical Man, staring hard at a coal in the
fire, “if Time is really only a fourth dimension of Space, why is it,
and why has it always been, regarded as something different? And why cannot
we move in Time as we move about in the other dimensions of
Space?”</p>
<p>The Time Traveller smiled. “Are you so sure we can move freely in
Space? Right and left we can go, backward and forward freely enough, and
men always have done so. I admit we move freely in two dimensions. But how
about up and down? Gravitation limits us there.”</p>
<p>“Not exactly,” said the Medical Man. “There are
balloons.”</p>
<p>“But before the balloons, save for spasmodic jumping and the
inequalities of the surface, man had no freedom of vertical
movement.”</p>
<p>“Still they could move a little up and down,” said the
Medical Man.</p>
<p>“Easier, far easier down than up.”</p>
<p>“And you cannot move at all in Time, you cannot get away from the
present moment.”</p>
<p>“My dear sir, that is just where you are wrong. That is just where
the whole world has gone wrong. We are always getting away from the present
moment. Our mental existences, which are immaterial and have no dimensions,
are passing along the Time-Dimension with a uniform velocity from the
cradle to the grave. Just as we should travel <i>down</i> if we began our
existence fifty miles above the earth’s surface.”</p>
<p>“But the great difficulty is this,” interrupted the
Psychologist. ’You <i>can</i> move about in all directions of Space,
but you cannot move about in Time.”</p>
<p>“That is the germ of my great discovery. But you are wrong to say
that we cannot move about in Time. For instance, if I am recalling an
incident very vividly I go back to the instant of its occurrence: I become
absent-minded, as you say. I jump back for a moment. Of course we have no
means of staying back for any length of Time, any more than a savage or an
animal has of staying six feet above the ground. But a civilised man is
better off than the savage in this respect. He can go up against
gravitation in a balloon, and why should he not hope that ultimately he may
be able to stop or accelerate his drift along the Time-Dimension, or even
turn about and travel the other way?”</p>
<p>“Oh, <i>this</i>,” began Filby, “is
all—”</p>
<p>“Why not?” said the Time Traveller.</p>
<p>“It’s against reason,” said Filby.</p>
<p>“What reason?” said the Time Traveller.</p>
<p>“You can show black is white by argument,” said Filby,
“but you will never convince me.”</p>
<p>“Possibly not,” said the Time Traveller. “But now you
begin to see the object of my investigations into the geometry of Four
Dimensions. Long ago I had a vague inkling of a machine—”</p>
<p>“To travel through Time!” exclaimed the Very Young Man.</p>
<p>“That shall travel indifferently in any direction of Space and
Time, as the driver determines.”</p>
<p>Filby contented himself with laughter.</p>
<p>“But I have experimental verification,” said the Time
Traveller.</p>
<p>“It would be remarkably convenient for the historian,” the
Psychologist suggested. “One might travel back and verify the
accepted account of the Battle of Hastings, for instance!”</p>
<p>“Don’t you think you would attract attention?” said
the Medical Man. “Our ancestors had no great tolerance for
anachronisms.”</p>
<p>“One might get one’s Greek from the very lips of Homer and
Plato,” the Very Young Man thought.</p>
<p>“In which case they would certainly plough you for the
Little-go. The German scholars have improved Greek so much.”</p>
<p>“Then there is the future,” said the Very Young Man.
“Just think! One might invest all one’s money, leave it to
accumulate at interest, and hurry on ahead!”</p>
<p>“To discover a society,” said I, “erected on a
strictly communistic basis.”</p>
<p>“Of all the wild extravagant theories!” began the
Psychologist.</p>
<p>“Yes, so it seemed to me, and so I never talked of it
until—”</p>
<p>“Experimental verification!” cried I. “You are going
to verify <i>that</i>?”</p>
<p>“The experiment!” cried Filby, who was getting
brain-weary.</p>
<p>“Let’s see your experiment anyhow,” said the
Psychologist, “though it’s all humbug, you know.”</p>
<p>The Time Traveller smiled round at us. Then, still smiling faintly, and
with his hands deep in his trousers pockets, he walked slowly out of the
room, and we heard his slippers shuffling down the long passage to his
laboratory.</p>
<p>The Psychologist looked at us. “I wonder what he’s
got?”</p>
<p>“Some sleight-of-hand trick or other,” said the Medical Man,
and Filby tried to tell us about a conjuror he had seen at Burslem, but before
he had finished his preface the Time Traveller came back, and Filby’s
anecdote collapsed.</p>
<h2><SPAN name="chap02"></SPAN>II.<br/> The Machine</h2>
<p>The thing the Time Traveller held in his hand was a glittering metallic
framework, scarcely larger than a small clock, and very delicately made.
There was ivory in it, and some transparent crystalline substance. And now
I must be explicit, for this that follows—unless his explanation is
to be accepted—is an absolutely unaccountable thing. He took one of
the small octagonal tables that were scattered about the room, and set it
in front of the fire, with two legs on the hearthrug. On this table he
placed the mechanism. Then he drew up a chair, and sat down. The only other
object on the table was a small shaded lamp, the bright light of which fell
upon the model. There were also perhaps a dozen candles about, two in brass
candlesticks upon the mantel and several in sconces, so that the room was
brilliantly illuminated. I sat in a low arm-chair nearest the fire, and I
drew this forward so as to be almost between the Time Traveller and the
fireplace. Filby sat behind him, looking over his shoulder. The Medical Man
and the Provincial Mayor watched him in profile from the right, the
Psychologist from the left. The Very Young Man stood behind the
Psychologist. We were all on the alert. It appears incredible to me that
any kind of trick, however subtly conceived and however adroitly done,
could have been played upon us under these conditions.</p>
<p>The Time Traveller looked at us, and then at the mechanism.
“Well?” said the Psychologist.</p>
<p>“This little affair,” said the Time Traveller, resting his
elbows upon the table and pressing his hands together above the apparatus,
“is only a model. It is my plan for a machine to travel through time.
You will notice that it looks singularly askew, and that there is an odd
twinkling appearance about this bar, as though it was in some way
unreal.” He pointed to the part with his finger. “Also, here is
one little white lever, and here is another.”</p>
<p>The Medical Man got up out of his chair and peered into the thing.
“It’s beautifully made,” he said.</p>
<p>“It took two years to make,” retorted the Time Traveller.
Then, when we had all imitated the action of the Medical Man, he said:
“Now I want you clearly to understand that this lever, being pressed
over, sends the machine gliding into the future, and this other reverses
the motion. This saddle represents the seat of a time traveller. Presently
I am going to press the lever, and off the machine will go. It will vanish,
pass into future Time, and disappear. Have a good look at the thing. Look
at the table too, and satisfy yourselves there is no trickery. I
don’t want to waste this model, and then be told I’m a
quack.”</p>
<p>There was a minute’s pause perhaps. The Psychologist seemed about
to speak to me, but changed his mind. Then the Time Traveller put forth his
finger towards the lever. “No,” he said suddenly. “Lend
me your hand.” And turning to the Psychologist, he took that
individual’s hand in his own and told him to put out his forefinger.
So that it was the Psychologist himself who sent forth the model Time
Machine on its interminable voyage. We all saw the lever turn. I am
absolutely certain there was no trickery. There was a breath of wind, and
the lamp flame jumped. One of the candles on the mantel was blown out, and
the little machine suddenly swung round, became indistinct, was seen as a
ghost for a second perhaps, as an eddy of faintly glittering brass and
ivory; and it was gone—vanished! Save for the lamp the table was
bare.</p>
<p>Everyone was silent for a minute. Then Filby said he was damned.</p>
<p>The Psychologist recovered from his stupor, and suddenly looked under
the table. At that the Time Traveller laughed cheerfully.
“Well?” he said, with a reminiscence of the Psychologist. Then,
getting up, he went to the tobacco jar on the mantel, and with his back to
us began to fill his pipe.</p>
<p>We stared at each other. “Look here,” said the Medical Man,
“are you in earnest about this? Do you seriously believe that that
machine has travelled into time?”</p>
<p>“Certainly,” said the Time Traveller, stooping to light a
spill at the fire. Then he turned, lighting his pipe, to look at the
Psychologist’s face. (The Psychologist, to show that he was not
unhinged, helped himself to a cigar and tried to light it uncut.)
“What is more, I have a big machine nearly finished in
there”—he indicated the laboratory—“and when that
is put together I mean to have a journey on my own account.”</p>
<p>“You mean to say that that machine has travelled into the
future?” said Filby.</p>
<p>“Into the future or the past—I don’t, for certain,
know which.”</p>
<p>After an interval the Psychologist had an inspiration. “It must
have gone into the past if it has gone anywhere,” he said.</p>
<p>“Why?” said the Time Traveller.</p>
<p>“Because I presume that it has not moved in space, and if it
travelled into the future it would still be here all this time, since it
must have travelled through this time.”</p>
<p>“But,” said I, “If it travelled into the past it would
have been visible when we came first into this room; and last Thursday when
we were here; and the Thursday before that; and so forth!”</p>
<p>“Serious objections,” remarked the Provincial Mayor, with an
air of impartiality, turning towards the Time Traveller.</p>
<p>“Not a bit,” said the Time Traveller, and, to the
Psychologist: “You think. <i>You</i> can explain that. It’s
presentation below the threshold, you know, diluted
presentation.”</p>
<p>“Of course,” said the Psychologist, and reassured us.
“That’s a simple point of psychology. I should have thought of
it. It’s plain enough, and helps the paradox delightfully. We cannot
see it, nor can we appreciate this machine, any more than we can the spoke
of a wheel spinning, or a bullet flying through the air. If it is
travelling through time fifty times or a hundred times faster than we are,
if it gets through a minute while we get through a second, the impression
it creates will of course be only one-fiftieth or one-hundredth of what it
would make if it were not travelling in time. That’s plain
enough.” He passed his hand through the space in which the machine
had been. “You see?” he said, laughing.</p>
<p>We sat and stared at the vacant table for a minute or so. Then the Time
Traveller asked us what we thought of it all.</p>
<p>“It sounds plausible enough tonight,” said the Medical Man;
“but wait until tomorrow. Wait for the common sense of the
morning.”</p>
<p>“Would you like to see the Time Machine itself?” asked the
Time Traveller. And therewith, taking the lamp in his hand, he led the way
down the long, draughty corridor to his laboratory. I remember vividly the
flickering light, his queer, broad head in silhouette, the dance of the
shadows, how we all followed him, puzzled but incredulous, and how there in
the laboratory we beheld a larger edition of the little mechanism which we
had seen vanish from before our eyes. Parts were of nickel, parts of ivory,
parts had certainly been filed or sawn out of rock crystal. The thing was
generally complete, but the twisted crystalline bars lay unfinished upon
the bench beside some sheets of drawings, and I took one up for a better
look at it. Quartz it seemed to be.</p>
<p>“Look here,” said the Medical Man, “are you perfectly
serious? Or is this a trick—like that ghost you showed us last
Christmas?”</p>
<p>“Upon that machine,” said the Time Traveller, holding the
lamp aloft, “I intend to explore time. Is that plain? I was never
more serious in my life.”</p>
<p>None of us quite knew how to take it.</p>
<p>I caught Filby’s eye over the shoulder of the Medical Man, and he
winked at me solemnly.</p>
