Well, maybe there isn't anything he should be able to see, but does that really matter? It's used to help visuilize the concepts of the dimentions
The awkward comes in thinking we might be only a few microns thick in that dimension or that we might have a more varied shape in that dimension that we have no clue about.
There's further awkwardness to think we have some extent in some dimension yet have no ability to turn any of our joints out of our hyperplane.
If we're only seeing a 3d slice of our bodies, we wouldn't see those tiny aspects of it turning out of our hyperplane. We...see only the surface of what we look at. What is turning or moving in the higher dimensions happens on the level of the smallest component of matter. We're only looking at a compilation of the 2d surface of each of those components that face our directional view at any time. Think of a 4d matrix turning around, but not as a whole, but each one of the tiny individual points within it turning around itself. Does that make sense?
If we and the universe are 4d, not only what we're looking at but what we're looking with is 4d too.
but then, i don't understand tony's theory...
Because as the object is infinitly thin and approaching zero, so is the entity seeing, and so is the realm they are in... if it ever reched zero though the being would cease to exist. So assuming they are still at some width that they do not understand, that width is still enough to exist and allow light to travel for sight.
if it were to actually reach zero it would no longer exist. So essentially you are saying that the 2nd dimension doesn't exist without the 3rd being there?
Looking downward onto the 2D realm from our realm (like in the drawings above) you can move the objects around in 2 dimensions. Up down and left right. These objects will collide; will they not?

If we can mass a 2D object (which yes we can... go to physics and calculus and you will learn howto), and one 2d object of a mass f passes through another 2d object of another mass g then the point of crossing would have to be a combination of both mass's. Which well means that something occured there! So even IF things didn't collide, they'd would atleast have to combine!
thickness doesn't matter for collision. collision is two objects making contact. the line y=x+2 crosses the line y=-x+2 at the point (0,2). That point (0,2) is a point of collision!
Your statement about life probably not existing in 2D... well I could easily believe and agree with that. But then we are not positive so you can not denounce it all together.
