Question

[Oneiros]

I am confused as to how a 2D world would appear to an inhabitant. If line segments are infinitely small in terms of height, then how would it be possible to see anything as everything would be infinitely short/thin? :?

Well it's hard for us to see anything if our vision is confined to a line, but not so for bionians (2d world inhabitants). I'm not sure how to explain it better, but bionians basically grow up with their vision confined to a line so it's not a problem.A tetronian (4d world inhabitant) would have difficulty understanding how we could see anything with our vision confined to a plane, since their vision is confined to a realm (a 3-plane). The image a single eye of ours receives is wide and high, and binocular vision gives it thickness, but it has no trength - it is infinitely tarrow.

you are thinking of a horizontal line. with vertical lines they have height but nothing else.
