Well, here's the thing though: If we were *all* blind, would the
   objective model be true? Or be true for us - and we may call it
   objective - yet the elephant may turn out to be something
   entirely different, for no matter how well we study it, we still
   won't be able to tell you everything; and could easily miss
   something important because we don't have the tools of
   discovery. We know what we know but we don't know what we don't
   know. I've seen it extended out to "can't know" but I think that
   kind of finality is an unnecessary extension. Also, I think that
   sometimes we can mix up "What is True?" with "What is better to
   teach as True?" and with "What can be treated as if True as it
   serves a function we consider to be important while not
   necessarily considering it True?"
