Ah, I see I had misunderstood what you were saying was inconsistent
with what.  I agree that I can see that the two assertions above are
inconsistent with one another, and I'm prepared to stipulate that with
enough OWL and inference to hand a machine could too.

What I _thought_ you had meant was that 

 http://xmlns.com/wordnet/1.6/Hoary_Marmot is_a "web page"

was _internally_ inconsistent.  I actually have come to believe that,
on the contrary, we'd be better off if we could reliably (and
automatically) conclude that

  http://xmlns.com/wordnet/1.6/Hoary_Marmot is_a "Hoary Marmot"

is internally inconsistent, but that's a subject for another and
longer posting.
