    But I hope that you will admit that while being that is true, it is
trivial given the mathematical Platonist assumption! What ideas do you have
about a "physicalist postulate"? What can I read to learn more about this?

    Maybe my question is: how does it make sense to talk about logical
statements and relations all the while declaring that the existence of the
manipulations of physical states is just the "possible relations between
numbers"? I understand somewhat how any logical statement can be encoded as
some string of numbers, that is a "Goedelization".
    Perhaps what I need to understand how the notion of "meaning" and "time"
are recovered. ;-)

    I am trying to use MIND as an equivalence class but an still strugling
with the notion of a "universal (and immaterial) machine".
     I understand the notion of a UTM but can not understand how one can
reason consistently about computations by it or any other "Machine" without
introducing temporality and motion in some way. This is the same as asking
how can software be said to exist without some way to implement it. It is in
the implementation that time, motion, thermodynamics and other complications

    Does the notion of observation itself even mean anything at the level of

    What is Time in your theory? Some kind of ordering? What makes it have,
at least the appearence, of beng absolute?

Kindest regards,
