    You're right, almost. But what _about_ the present? Without an
_objective_ measure on possible experiences, there would be no reason for
even the present moment to be as wabbit-free as it is! (e.g. The present
moment suggests evolution, etc.)
    And you can never see the future (maybe you _will_, depending on the
definition of "you", but you never have yet!), so clearly it is only the
present that supplies the info you have to make such Bayesian deductions.
In fact it's simpler to define "you" as just existing now.
(Which is not to say your utility function shouldn't care about future
    It should be apparent to all that an objective measure is needed on
observer-moments. I do not call this a "3rd person" measure because that
would falsely imply the existance of some other type of measure to be a
logical possibility.
