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.
