I started this message a couple days ago and it may now be out of

Yikes! I guess if you define objective reality that way then I
agree. And I can see that that is a plausible definition of
objective reality as follows: Our subjective experiences are
caused by the movement of electrons in our brains and our brains
and their electrons are part of objective reality so our
subjective experiences are part of objective reality. Is this
what you're getting at?

But I can never experience your subjective reality. What we *can*
share is objective reality. I may say that the colour is blue-green
while you insist that it is green-blue but we can sit down
and use a spectrograph to determine how many photons of each
wavelength range the object is reflecting/emitting. We may still
argue about whether it seems more green or more blue but at least
we can agree about the more objective properties.

All of those terms can be defined very precisely. Yes, I agree
that it is probably not possible to fully satisfy someone who is
trying to think of all possible objections, right down to the
definitions of all the words and the words used to explain the
words etc. But that person also probably doesn't really believe
hir objections because s/he would have been selected against long
ago :-)
