I have put this to you in the past, but you have always responded that the multiple universes always emerges out of the UD, leaving me most confused as to whether I support the COMP position or not. > Your move could belong to what I will perhaps eventually call "the > magical use of matter for explaining (away) consciousness".

Physical supervenience is not equivalent to assuming a concrete primitive material world. The latter is an additional assumption. > We should come back on this in a "the 8th step" (movie graph) thread. > > Bruno > > > http://iridia.ulb.ac.be/~marchal/ > > > -- *PS: A number of people ask me about the attachment to my email, which is of type "application/pgp-signature".
