Chapter 17 — Section 16. How the Stranger vainly endeavoured to reveal to me in words the mysteries of Spaceland Central question Why are words still not enough once a higher dimension has appeared? Main...
As soon as the sound of the Peace-cry of my departing Wife had died
away, I began to approach the Stranger with the intention of taking a
nearer view and of bidding him be seated: but his appearance struck me
dumb and motionless with astonishment. Without the slightest symptoms
of angularity he nevertheless varied every instant with gradations of
size and brightness scarcely possible for any Figure within the scope
of my experience. The thought flashed across me that I might have
before me a burglar or cut-throat, some monstrous Irregular Isosceles,
who, by feigning the voice of a Circle, had obtained admission somehow
into the house, and was now preparing to stab me with his acute angle.
In a sitting-room, the absence of Fog (and the season happened to be
remarkably dry), made it difficult for me to trust to Sight
Recognition, especially at the short distance at which I was standing.
Desperate with fear, I rushed forward with an unceremonious, "You must
permit me, Sir--" and felt him. My Wife was right. There was not the
trace of an angle, not the slightest roughness or inequality: never in
my life had I met with a more perfect Circle. He remained motionless
while I walked round him, beginning from his eye and returning to it
again. Circular he was throughout, a perfectly satisfactory Circle;
there could not be a doubt of it. Then followed a dialogue, which I
will endeavour to set down as near as I can recollect it, omitting only
some of my profuse apologies--for I was covered with shame and
humiliation that I, a Square, should have been guilty of the
impertinence of feeling a Circle. It was commenced by the Stranger
with some impatience at the lengthiness of my introductory process.
STRANGER. Have you felt me enough by this time? Are you not
introduced to me yet?
I. Most illustrious Sir, excuse my awkwardness, which arises not from
ignorance of the usages of polite society, but from a little surprise
and nervousness, consequent on this somewhat unexpected visit. And I
beseech you to reveal my indiscretion to no one, and especially not to
my Wife. But before your Lordship enters into further communications,
would he deign to satisfy the curiosity of one who would gladly know
whence his Visitor came?
STRANGER. From Space, from Space, Sir: whence else?
I. Pardon me, my Lord, but is not your Lordship already in Space, your
Lordship and his humble servant, even at this moment?
STRANGER. Pooh! what do you know of Space? Define Space.
I. Space, my Lord, is height and breadth indefinitely prolonged.
STRANGER. Exactly: you see you do not even know what Space is. You
think it is of Two Dimensions only; but I have come to announce to you
a Third--height, breadth, and length.
I. Your Lordship is pleased to be merry. We also speak of length and
height, or breadth and thickness, thus denoting Two Dimensions by four
names.
STRANGER. But I mean not only three names, but Three Dimensions.
I. Would your Lordship indicate or explain to me in what direction is
the Third Dimension, unknown to me?
STRANGER. I came from it. It is up above and down below.
I. My Lord means seemingly that it is Northward and Southward.
STRANGER. I mean nothing of the kind. I mean a direction in which you
cannot look, because you have no eye in your side.
I. Pardon me, my Lord, a moment's inspection will convince your
Lordship that I have a perfect luminary at the juncture of two of my
sides.
STRANGER. Yes: but in order to see into Space you ought to have an
eye, not on your Perimeter, but on your side, that is, on what you
would probably call your inside; but we in Spaceland should call it
your side.
I. An eye in my inside! An eye in my stomach! Your Lordship jests.
STRANGER. I am in no jesting humour. I tell you that I come from
Space, or, since you will not understand what Space means, from the
Land of Three Dimensions whence I but lately looked down upon your
Plane which you call Space forsooth. From that position of advantage I
discerned all that you speak of as SOLID (by which you mean "enclosed
on four sides"), your houses, your churches, your very chests and
safes, yes even your insides and stomachs, all lying open and exposed
to my view.
I. Such assertions are easily made, my Lord.
STRANGER. But not easily proved, you mean. But I mean to prove mine.
When I descended here, I saw your four Sons, the Pentagons, each in his
apartment, and your two Grandsons the Hexagons; I saw your youngest
Hexagon remain a while with you and then retire to his room, leaving
you and your Wife alone. I saw your Isosceles servants, three in
number, in the kitchen at supper, and the little Page in the scullery.
Then I came here, and how do you think I came?
I. Through the roof, I suppose.
STRANGER. Not so. Your roof, as you know very well, has been recently
repaired, and has no aperture by which even a Woman could penetrate. I
tell you I come from Space. Are you not convinced by what I have told
you of your children and household?
I. Your Lordship must be aware that such facts touching the belongings
of his humble servant might be easily ascertained by any one in the
neighbourhood possessing your Lordship's ample means of obtaining
information.
STRANGER. (TO HIMSELF.) What must I do? Stay; one more argument
suggests itself to me. When you see a Straight Line--your wife, for
example--how many Dimensions do you attribute to her?
I. Your Lordship would treat me as if I were one of the vulgar who,
being ignorant of Mathematics, suppose that a Woman is really a
Straight Line, and only of One Dimension. No, no, my Lord; we Squares
are better advised, and are as well aware as your Lordship that a
Woman, though popularly called a Straight Line, is, really and
scientifically, a very thin Parallelogram, possessing Two Dimensions,
like the rest of us, viz., length and breadth (or thickness).
STRANGER. But the very fact that a Line is visible implies that it
possesses yet another Dimension.
I. My Lord, I have just acknowledged that a Woman is broad as well as
long. We see her length, we infer her breadth; which, though very
slight, is capable of measurement.
STRANGER. You do not understand me. I mean that when you see a Woman,
you ought--besides inferring her breadth--to see her length, and to SEE
what we call her HEIGHT; although that last Dimension is infinitesimal
in your country. If a Line were mere length without "height", it would
cease to occupy Space and would become invisible. Surely you must
recognize this?
I. I must indeed confess that I do not in the least understand your
Lordship. When we in Flatland see a Line, we see length and
BRIGHTNESS. If the brightness disappears, the Line is extinguished,
and, as you say, ceases to occupy Space. But am I to suppose that your
Lordship gives to brightness the title of a Dimension, and that what we
call "bright" you call "high"?
STRANGER. No, indeed. By "height" I mean a Dimension like your
length: only, with you, "height" is not so easily perceptible, being
extremely small.
I. My Lord, your assertion is easily put to the test. You say I have
a Third Dimension, which you call "height". Now, Dimension implies
direction and measurement. Do but measure my "height", or merely
indicate to me the direction in which my "height" extends, and I will
become your convert. Otherwise, your Lordship's own understanding must
hold me excused.
STRANGER. (TO HIMSELF.) I can do neither. How shall I convince him?
Surely a plain statement of facts followed by ocular demonstration
ought to suffice. --Now, Sir; listen to me.
You are living on a Plane. What you style Flatland is the vast level
surface of what I may call a fluid, on, or in, the top of which you and
your countrymen move about, without rising above it or falling below it.
I am not a plane Figure, but a Solid. You call me a Circle; but in
reality I am not a Circle, but an infinite number of Circles, of size
varying from a Point to a Circle of thirteen inches in diameter, one
placed on the top of the other. When I cut through your plane as I am
now doing, I make in your plane a section which you, very rightly, call
a Circle. For even a Sphere--which is my proper name in my own
country--if he manifest himself at all to an inhabitant of
Flatland--must needs manifest himself as a Circle.
Do you not remember--for I, who see all things, discerned last night
the phantasmal vision of Lineland written upon your brain--do you not
remember, I say, how, when you entered the realm of Lineland, you were
compelled to manifest yourself to the King, not as a Square, but as a
Line, because that Linear Realm had not Dimensions enough to represent
the whole of you, but only a slice or section of you? In precisely the
same way, your country of Two Dimensions is not spacious enough to
represent me, a being of Three, but can only exhibit a slice or section
of me, which is what you call a Circle.
The diminished brightness of your eye indicates incredulity. But now
prepare to receive proof positive of the truth of my assertions. You
cannot indeed see more than one of my sections, or Circles, at a time;
for you have no power to raise your eye out of the plane of Flatland;
but you can at least see that, as I rise in Space, so my sections
become smaller. See now, I will rise; and the effect upon your eye
will be that my Circle will become smaller and smaller till it dwindles
to a point and finally vanishes.

There was no "rising" that I could see; but he diminished and finally
vanished. I winked once or twice to make sure that I was not dreaming.
But it was no dream. For from the depths of nowhere came forth a
hollow voice--close to my heart it seemed--"Am I quite gone? Are you
convinced now? Well, now I will gradually return to Flatland and you
shall see my section become larger and larger."
Every reader in Spaceland will easily understand that my mysterious
Guest was speaking the language of truth and even of simplicity. But
to me, proficient though I was in Flatland Mathematics, it was by no
means a simple matter. The rough diagram given above will make it
clear to any Spaceland child that the Sphere, ascending in the three
positions indicated there, must needs have manifested himself to me, or
to any Flatlander, as a Circle, at first of full size, then small, and
at last very small indeed, approaching to a Point. But to me, although
I saw the facts before me, the causes were as dark as ever. All that I
could comprehend was, that the Circle had made himself smaller and
vanished, and that he had now reappeared and was rapidly making himself
larger.
When he regained his original size, he heaved a deep sigh; for he
perceived by my silence that I had altogether failed to comprehend him.
And indeed I was now inclining to the belief that he must be no Circle
at all, but some extremely clever juggler; or else that the old wives'
tales were true, and that after all there were such people as
Enchanters and Magicians.
