It is clear that we don't think the same way. M(x) is simply the total
measure of observations with the characteristic x. M(x|y), on the other
hand, is undefined since "observer" is undefined. I don't understand what
you mean by M(x|z).
For the sake of others who may have forgotten, I'll describe again what
is involved. The problem is to compare the measaure of 1) x = "you are the
product of Darwinian evolution" and 2) x' = "you are the direct result of
(quantum or thermal) 'random fluctuations'". Presumably, x and x' would be
seen by different 'observers' if that was defined.

And here I thought you were an everything-ist.
As you know, I'd sum over all implementations in the multi-multiverse to
find a measure.

Then you should have posted the above to the list, no doubt an
oversight.
The problem is that most of the active posters are under delusions
similar to yours. Those who believe in (e.g.) QTI must be more likely than
sane people to join the everything-list and to post.
