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.
