a romance of at least 3 dimensions

A square is sitting alone in his two-dimensional home.
A cube, a being of three-dimensions, visits.

“Upwards, not forwards.” The cube instructs.
“Length, width, and height.”
But the square does not understand.
After all, there are only two dimensions.

“What is height?” The square asks.
Its two-dimensional mind cannot grasp such a concept.
“Imagine yourself. A square. Four lines.
Made up of four one dimensional shapes.
I am like you, but I am a cube.
I am a being made up of six two-dimensional shapes, squares, like you.
Eight vertices, rather than four.”
Despite Geometric Proofs, the cube does not understand.

“Allow me to show you,” The cube says.
All at once, the square is thrust above the world of two dimensions,
And into the world of three.
“I understand now!” the square cries, seeing what’s beyond the world it knew
“And why did you doubt me before?” The cube asks.
After all, for the cube, this is common knowledge.
Of course there are three dimensions.
“It’s simply unbelievable!” The square responds. “Not without seeing it.”
“But you know it to exist now.” The cube replies.
The square does not reply.
“What is on your mind?” The cube asks.
“What comes after three dimensions? What is the fourth like?”
The cube is silent. The square pushes.
“What of a being made up of eight cubes? Sixteen vertices?”
“You speak of the impossible. There cannot be such a thing.”
The cube hides its anger, and dismisses the square back to the world of two dimensions.

A hypercube, a being of four dimensions, visits.

pov: you are a hypercube-->
