OK, as I understand your ontology it is something like: mathematics->computation->consciousness->material But this seems to still leave the problems of dualism because it allows that a consciousness (e.g. mine) can be generated without any associated material (e.g. a brain) and also that consciousnesses can generate another brain (e.g. duplicate of mine) with no associated consciousness. I take it that this is the 'indeterminism' you illustrate by the Washington/Moscom duplication experiment. I had never been able to understand what indeterminism you referred to until now. Now I see that you suppose that the original consciousness will go into one of the duplicates and the other will be void of consciousness. Is this correct?
