Since you agree that the number of histories is on a continuum, you 
must accept that no matter how large or small a segment of the 
continuum is considered, the number of histories is the same. Hence 
measure is the same for any observer.



The whole concept of "measure" is based on assigning different 
probabilities to different infinite sets--the fact that two sets 
have the same cardinality doesn't imply they must have the same 
measure. For example, any continuous probability distribution used 
in statistics (the bell curve, for example) can be used to assign a 
measure to an arbitrary finite interval (which necessarily contains 
an infinite number of points), the measure just being the area under 
the curve over that interval.

Jesse I agree with you from the third person perspective. You can 
only take a measure of infinite sets when you have more then one set 
. In other words you need at least two sets so you can compare them. 
However in the case of first person perspective, the observer has 
only his own set. All he has is the cardinality of the set and he has 
only one set. No other set to compare it to. The cardinality is the 
same for all first person observers.

But if you have one set with an infinite number of elements, you can 
assign different measures to different infinite subsets of that set. 
And weren't you talking about an infinite "number of histories" above?

Jesse,
the infinite number of histories refer to the continuum of histories. 
The first person observer can only perceive through his own experiments 
that physics in his own world, provides a infinite number of histories 
as large as the continuum.  All he knows is that his own history  is 
embedded in a continuum of histories.
