I have probably missed something (in the 10^9 episodes!), but I still cannot figure out why should "my" measure decrease with "time". At least with comp, it seems to me that the measure can only grow, for I can have only a countable set of past histories, and (even "without immortality") "I" have a uncountable set of futur "histories" (continuations). If you (or any one else) could elaborate on this, and/or refer me to the discussion-list, or to an URL, it would help me to understand the point. You also seem to know what precisely the "measure" is. In http://iridia.ulb.ac.be/~marchal I give a *proof* that if comp is correct then we MUST isolate "physics" from such a measure. After that, I use modal and provability logic to illustrate how to construct a path TOWARD such a measure. I aknowledge that I am at a billion miles from having isolate it ..., and I'm still open to the idea that such a measure doesn't exist (in wich case comp would be false). Where does your assurance come from ? Bruno.
