Do you mean to say that we can't recover the 1-person from a physical
universe on the assumption that the mind is a 'computation' executed
by elements of a physical brain, or that it can't be recovered *in any
manner* on the assumption of 'physical ontology'? I've always assumed
the former - which is the one attacked in your thought experiments;
the latter would be a much stronger and more startling claim, to say
the least.

Yes, I should have said 'otherwise intractable' - meaning intractable
for any schema that doesn't explicitly generate the dreamers and their
many viewpoints as well as their dream contents. This is the problem
space that must be confronted - as COMP does. My point is that any
approach to the mind-body issues that doesn't tackle this must fail at
the outset. Agreed?

I'm still trying! I must say that the more I think about your
arguments in detail (some of the basic ones - like the teleportation
examples - have direct counterparts in my own intuitive history) the
more they exercise my intuitions in helpful directions. I feel that
there is something intuitively necessary in this generative approach,
and specifically in the way it seeks to resolve the 0-1-3-person
conundrums that - even if it turns out to be unsupportable as a whole
- would remain a core feature of any successor theory.
