Many Worlds and A priori Knowledge

1. If MWI is true then all physical possibilities are realized (Saunders 1998)
2. All realized possibilities are decoherent with each other
3. Decoherence implies that no experience in the sense physics puts behind this term could transcend the actual physical possibility [to use the conventional term “world”] of an observer
4. Hence, no observer in one world could have some experience about what is going on in a different world
5. Still, observers could have some knowledge about decoherent worlds
6. Experiential or non-experiential [a priori] knowledge
7. Therefore, observers could have [some] a priori knowledge about decoherent worlds

Some photos from Dubrovnik conference 2006

More than half of the photos are disfocused due to the slow camera shutter. Mostly the ones in the lecture halls. The ones where objects (and people for that matter) are shot in motion are basically ruined. My first reaction was to delete all of the ruined ones but then, even some of the disfocued ones bring memories which will fade away without them so I decided to leave them as they are. Apologies for unpleasant representation of what happened to be a nice event.

The Oxonian Everettian Repsonse

James Ladyman gave a talk at Philosophy of Physics conference in Dubrovnik where he posed some questions about the Oxonian Everettian (Saunders, Deutsch, Wallace). Harvey Brown summarized as a response the following crucial point: it is not the branching but the multiplicity that is the real problem that has to be solved. My intuition is that he is quite right about that and that proper effort should be directed to solve the problem of multiplicity.

Remark: several years ago such debate would have been impossbile. Brown himself recognized that it took him years to realize the non-schizo component behind the MWI. Now, everyone is talking about MW. I had the feeling some 7 years ago that this is exactly what is going to happen, I just did not expect to be so soon.

Dubrovnik conference April 2006

In brief:

AMAZING talk by Harvey Brown, Oxford. About the Role of geometry in physics. Briefly: not so big.

Devastating talk by Butterfield. On Harvey Brown :).

Cute Talks by Nenad and Danny. Still waiting the hard core stuff by James Ladyman and Oliver Pooley as well as Itamar Pitowsky.

Bad weather, TRUBADUR is practically not working.
