“On the other hand, I don’t think that healing the man born blind had anything to do with ability to do calculus, manipulate words, solve IQ puzzles, or engage in deep philosophical discussion.”

True, if all existence falls within the laws of nature. I think our spirits know things we're unable to wrap our minds around, because they are partially outside of the laws of nature as we know them.
