The little Hexagon meditated on this a while and then said to me; 〃But you have been teaching me to raise numbers to the third power: I suppose 3^3 must mean something in Geometry; what does it mean?〃 〃Nothing at all;〃 replied I; 〃not at least in Geometry; for Geometry has only Two Dimensions。〃 And then I began to shew the boy how a Point by moving through a length of three inches makes a Line of three inches; which may be represented by 3; and how a Line of three inches; moving parallel to itself through a length of three inches; makes a Square of three inches every way; which may be represented by 3^2。
Upon this; my Grandson; again returning to his former suggestion; took me up rather suddenly and exclaimed; 〃Well; then; if a Point by moving three inches; makes a Line of three inches represented by 3; and if a straight Line of three inches; moving parallel to itself; makes a Square of three inches every way; represented by 3^2; it must be that a Square of three inches every way; moving somehow parallel to itself (but I don't see how) must make Something else (but I don't see what) of three inches every way and this must be represented by 3^3。〃
〃Go to bed;〃 said I; a little ruffled by this interruption: 〃if you would talk less nonsense; you would remember more sense。〃
So my Grandson had disappeared in disgrace; and there I sat by my Wife's side; endeavouring to form a retrospect of the year 1999 and of the possibilities of the year 2000; but not quite able to shake off the thoughts suggested by the prattle of my bright little Hexagon。 Only a few sands now remained in the half…hour glass。 Rousing myself from my reverie I turned the glass Northward for the last time in the old Millennium; and in the act; I exclaimed aloud; 〃The boy is a fool。〃
Straightway I became conscious of a Presence in the room; and a chilling breath thrilled through my very being。 〃He is no such thing;〃 cried my Wife; 〃and you are breaking the Commandments in thus dishonouring your own Grandson。〃 But I took no notice of her。 Looking round in every direction I could see nothing; yet still I FELT a Presence; and shivered as the cold whisper came again。 I started up。 〃What is the matter?〃 said my Wife; 〃there is no draught; what are you looking for? There is nothing。〃 There was nothing; and I resumed my seat; again exclaiming; 〃The boy is a fool; I say; 3^3 can have no meaning in Geometry。〃 At once there came a distinctly audible reply; 〃The boy is not a fool; and 3^3 has an obvious Geometrical meaning。〃
My Wife as well as myself heard the words; although she did not understand their meaning; and both of us sprang forward in the direction of the sound。 What was our horror when we saw before us a Figure! At the first glance it appeared to be a Woman; seen sideways; but a moment's observation shewed me that the extremities passed into dimness too rapidly to represent one of the Female Sex; and I should have thought it a Circle; only that it seemed to change its size in a manner impossible for a Circle or for any regular Figure of which I had had experience。
But my Wife had not my experience; nor the coolness necessary to note these characteristics。 With the usual hastiness and unreasoning jealousy of her Sex; she flew at once to the conclusion that a Woman had entered the house through some small aperture。 〃How comes this person here?〃 she exclaimed; 〃you promised me; my dear; that there should be no ventilators in our new house。〃 〃Nor are there any;〃 said I; 〃but what makes you think that the stranger is a Woman? I see by my power of Sight Recognition 〃 〃Oh; I have no patience with your Sight Recognition;〃 replied she; 〃'Feeling is believing' and 'A Straight Line to the touch is worth a Circle to the sight'〃 two Proverbs; very common with the Frailer Sex in Flatland。
〃Well;〃 said I; for I was afraid of irritating her; 〃if it must be so; demand an introduction。〃 Assuming her most gracious manner; my Wife advanced towards the Stranger; 〃Permit me; Madam; to feel and be felt by 〃 then; suddenly recoiling; 〃Oh! it is not a Woman; and there are no angles either; not a trace of one。 Can it be that I have so misbehaved to a perfect Circle?〃
〃I am indeed; in a certain sense a Circle;〃 replied the Voice; 〃and a more perfect Circle than any in Flatland; but to speak more accurately; I am many Circles in one。〃 Then he added more mildly; 〃I have a message; dear Madam; to your husband; which I must not deliver in your presence; and; if you would suffer us to retire for a few minutes 〃 But my Wife would not listen to the proposal that our august Visitor should so incommode himself; and assuring the Circle that the hour of her own retirement had long passed; with many reiterated apologies for her recent indiscretion; she at last retreated to her apartment。
I glanced at the half…hour glass。 The last sands had fallen。 The third Millennium had begun。
Section 16。 How the Stranger vainly endeavoured to reveal to me in words the mysteries of Spaceland
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 o
