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?"
