RE: NPR, Godel, Semantic Web

Correct me if I'm wrong, but doesn't the incompleteness theorem come into
play when you bring in arithmetic into logic? I can't think how the kind of
logic that's being talked about for the semantic web is likely to stray into
this territory. In any case - what's the likely problem? Ok, within any
given system of axioms, we can't prove all maths, but how might this affect
the web? I think the theories of chaos might have a little more bearing on
likely problems - all the feedback, all the non-linearity - should be fun.

BTW, I am not a logician. In fact, I got so frustrated trying to grasp
something apparently elementary the other day that I've just bought a copy
of 'The Language of First-Order Logic', which starts *really easy* and goes
just up to Godel's I.T., and there's also some software with it that allows
you to argue about a simple world of brightly coloured objects (joy!). I've
also ordered the legendary Wff'n'Proof as a fallback, though by the time it
arrives from the states hopefully I won't need it...
