I grant you that an omnipotent being could invalidate all possible sets of axioms IF IT EXISTED. But the proof shows that it doesn't, and it does so without denying the being's ability to do any particular thing, including denying axioms. You may, of course, claim that there is an omnipotent being who has presented us with a logic that appears to work in all cases that we can verify, but which does not apply to herself. The argument then reduces to "either there is no omnipotent being, or all of logic (and all of mathematics) is just an illusion." Obviously the continuation of that argument does not belong in sci.math. -- Dave Seaman ags@j.cc.purdue.edu
