But I found that I had no motion of my own.
I absolutely depended on the volition of my Guide, who said in gloomy tones,
"Heed not thy brother; haply thou shalt have ample time hereafter
to condole with him. Follow me."
Once more we ascended into space. "Hitherto," said the Sphere,
"I have shewn you naught save Plane Figures and their interiors.
Now I must introduce you to Solids, and reveal to you the plan upon which
they are constructed. Behold this multitude of moveable square cards.
See, I put one on another, not, as you supposed, Northward of the other,
but ON the other. Now a second, now a third. See, I am building up
a Solid by a multitude of Squares parallel to one another.
Now the Solid is complete, being as high as it is long and broad,
and we call it a Cube."
"Pardon me, my Lord," replied I; "but to my eye the appearance
is as of an Irregular Figure whose inside is laid open to view;
in other words, methinks I see no Solid, but a Plane such as we
infer in Flatland; only of an Irregularity which betokens some
monstrous criminal, so that the very sight of it is painful to my eyes.
