Re: SUO: Re: Ballot Comment




John,
   Forgive me for speaking somewhat bluntly below.  I don't wish to offend 
but I think you really have to be more concrete.  You've said a single 
ontology won't work but I think there's a burden of proof on you to show in 
detail why.  In contract, the SUMO proposal is a very concrete effort to 
show how it will work to have a single ontology.  If you wish to show that 
it won't work please define

1.  ...what it means precisely in logic that it "doesn't work".  Does this 
mean that both P and (not P) are derivable from axioms in the ontology?  Or 
something else?

2.  ...a proof which shows that the definition of "doesn't work" above is 
satisfied from axioms in SUMO

Otherwise, this is an unjustified criticism.  An opinion of value due to 
the strength of your accomplishments and intuitions, but hardly a precise 
criticism.  You've made a reasonable case for why you can have a lattice of 
theories.  I agree that's possible too (by the way I don't see that you've 
given any examples below counter to a single ontology, just statements 
about a lattice).  But you haven't shown that a single ontology is impossible.
