One more thought / question on this point:
If we were to add a separate subforum on "Rhetoric" at some point (and not just under Philodemus) would that be clearly more appropriate for the "Ethics" section, or is it possible that it should be considered under "Canonics?"
That in itself is possibly an interesting discussion. Is part of the problem with "rhetoric" that it is being asserted to be a standard of truth? Or is it clearly and distinctly an issue of Ethics/Politics?
