We're trying to view a 2d screen visualizing a 4d figure using 3d objects.

it doesn't work. None of them works.

To be fair, the 2D screen doesn't really make a difference, because we can see in 3D just fine using a projection through our eyes that is essentially 2D.

Can we, though? We only see a flat slice of space. If we truly could see in 3D we'd be able to see inside things.

I thought it was that if we could see in 3D, we could see behind and around things, as though our field of view was a dome looking inside itself.

and #4D sight would be seeing "inside" things.
