fundamentally on what one means by all those words:
"model", "wrong", "useful" - 3 unknowns, assuming "some"
and "all" are understood as quantifiers and "are" is
understood as membership/identity. The problem with the EO
Wilson aphorism was that it was too short. This one is
even shorter. As I tried to hint at in my comment about
*solving* for the meaning of a variable in a sentence, the
fewer the sentences, the less meaning the sentences have.
Why not simply reduce all aphorisms to Mu and be done with
it?<br>

bisimulation ever exists between machines. It is fine, I
suppose, as a world view, but proving bisimulation between
things also seems fine.<br>

model universal computers, limitations of various types
can render any particular model useless. Only partially
with tongue-in-cheek, I am not sure anyone has ever found
Turing's machine to be useful for anything other than
getting a passing grade on a senior year project. In the
case of ants, do we really have to wait so long?<br>
