I followed you up until that paragraph. Why should the rebirth from a no-consciousness state say anything about the substrate on which consciousness runs? It matters only that there be some entity that remembers being the entity that faded away for that entity to be reborn. How that entity is implementedt and whether it is even causally related to the first entity in any way is irrelevant. > The Turing principle (p135 of David Deutsch’s book – “the Fabric of > Reality”) would imply that, a universal machine could simulate the > physical structure of brains in such a way so as to be able to act as > a medium whereby, if the above argument is possible, consistent > extensions of conscious physical observers (persons) could avoid cul > de sacs.

That we don't see extremely old people is consistent with QTI, since from the third person perspective rare events such as living to a great age happen only rarely. However, from the first person perspective you will live to a great age, and this will happen in the most probable way, even if it is improbable in absolute (third person) terms. > The mechanics of such reincarnational transitions would be > interesting to speculate about since I see this as the only way out > for a QTI. > > Nick Prince - Stathis Papaioannou -- You received this message because you are subscribed to the Google Groups "Everything List" group.
