Unfortunately the man who thinks he can “see” doesn’t see the underlying reality of energy waves and molecules that make up the true reality of what we call “elephant”. And so, the gist of the fable is that some might know more than others, but true understanding is an illusion.
I'll go out on a limb -- Truth is a illusion with a purpose. It is that purpose which is real. Moreover, for us, truth is all we have to work with, and for that we'd best stick with truth, because it is the only path to our purpose.
