OK, point taken. Yes, if we were to set out to do
an ontology of mental life or agency or
consciousness or whatever, like your
Peirce-in-OWL (wow!) then 'concept' might well be
a category or classification in that ontology
(though I would like to read the explanation of
it very carefully :-). But what we were debating,
I think, is whether we need to talk about
concepts when talking about the whole business of
ontology engineering itself, regardless of the
topic; whether the very idea of a concept
(concept of a concept??) must be part of our
ontology metatheory, a term of art in our very
discipline. That's the view I was arguing (well,
not exactly arguing) against, in any case. (02)
