It would be quite interesting.

My counter-point to your counter-point is thus: In theory, if one had absolutely no conception of the baseball, no possible perception or logical awareness, one could, potentially, be unaffected by it. Consider it a sort of mind over matter. In theory, if one was completely unaware of the effect of gravity, even in the most basic of senses, one could fly. But, like all those old Saturday morning cartoons, if that same person was suddenly taught that all things are drawn towards a greater body unless suspended in some way, that floating person would plummet to the Earth like the rest of us. Of course, this is just theory.
