As usually happens in debates of this sort, it has degenerated into
dictionary definitions and semantics. Nobody can win this debate. Greater
minds than you have failed. If you want to see where it ultimately leads,
read Wittgenstein's "On Certainty". Then laugh out loud at a billiant man
hopelessly bogged down in semantics, trying (and failing) to create an
air-tight argument for his own existance.
Please, for the sake of the bandwidth... for the sake of whatever it is that
you're supposed to be doing right now... drop it.
