what is an object? take the physics of quasiparticles and the whole idea of objects falls apart what constitutes the identity of an object? take the physics of fermion, boson, anyon statistics and compare with maxwell-boltzmann; take the Gibbs paradox but if these topics are a prerequisite for discussing ontology, who can take part in the discussion? it takes the fun out of philosophy </lecture>

Migeru: it's funny how QM philosophical problems always end up at the conscious observer ... but I think it's about philosophy, not about quantum consciousness Colman: Yes. Migeru: it's like the philosophhy of probability: it's also broken Colman: It's an artificial split between system and observer. Or somethign along those lines. Migeru: do you know about the holographic principle in quantum gravity? Colman: I've heard of it. But I forget... Migeru: it says roughly... you can put a boundary wherever you want the area of the boundary is a bound on the information entropy of either half it appears likely to be a key principle of the new theory but quite what it has to do with consciousness... though it does seem to have something to do with these boundaries between systems Colman: Hm. Migeru: subject and object, etc Colman: Could do. The distincition is artifical. Migeru: the problem is since we don't understand consciousness we can't do a toy model of a self-aware entity Colman: No. Migeru: so there's no way to put that in QM and talking about QM as the basis of consciousness just confuses things even more!
