The sphere is no more barrier to him than the circle was to 3D man. To 3D man this is a miracle.

The analogy doesn't play out in reality. Stop a bunch of our 4 diminsional college grads and quiz them on some 2D geometry fundamentals or 3D situations and you'll find they rarely have a clue about the principles at work in the lower dimensions. In that sense they would seem god-like in that they do bungle a lot of simple stuff.
