Contemplating a Four Dimensional World

I've been reading the book "Flatland" by Edwin A. Abbott. It's about a square in a two dimensional universe (three, if you include time, but the book doesn't, so whatever). It was first published in 1884, so it's considered a classic. It's also awesome.

Anyway, "A. Square," our main character, sees the universe in one-dimension, or as a straight line, despite that he lives in a two-dimensional world.

We live in a three-dimensional world and see in two-dimensions, ignoring depth perception which gives us pseudo-three-dimensional vision by utilizing two perspectives.

In a four-dimensional world, one would see in three-dimensions, a perspective almost incomprehensible to the human mind.
