Hoyle wan't necessarily assuming comp (and nor do I when talking in this
way). But the point which I have consistently tried to put to you is more
basic. This is that "the relative indeterminacy of the relative first
person perspective" already, by that very formulation, assumes without
justification (albeit rather inexplicitly) some specific relative
localisation within what is, more properly considered, an indifferent
ensemble (e.g. UD* or alternatively some cosmological SWE). Hoyle's way of
thinking makes the indeterminate localisation of experience explicit and *
absolute* at the outset: he just imagines, in effect, what would it be
"like" if the ensemble of all possible occasions of sentience were
"unrolled" stochastically in a sort of eternal recurrence. This gives,
effectively, a relative-frequency interpretation of the probability of any
particular occasion being presently "given".
*But then such stochastic process will interfere with the outcomes of
duplication, and transportation, at least to make sense. But then it might
be in conflict with computationalism.*
I don't see why you think so. The experiences associated with each
duplication or transportation outcome are assumed to be present in the
deterministic substrate in due measure, and hence to occur in the
associated stream of consciousness in due course. That there is always
some given occasion of experience is consequent on an absolute
first-personal indeteminism; relativisation to an episode of a particular
personal history is then dependent on whatever deterministic substrate is
associated with the given occasion. "Relative amnesia" (or selective
memory) effectively compartmentalises first-personal histories from each
other and is consequently transparent to "reconstitution delay".
The above considerations seem so basic to our disagreement that rather than
comment further on your other points, I will await your response to this.
It is of course perfectly possible (not to say likely) that I am missing
something basic here, so I am trying to be as explicit as possible. Let me
know what, if anything, is still unclear.
