Hi Bruce, I'm not satisfied with Bruno's answer here, so let me try my perspective. Computational supervenience states that two counterfactually equivalent computations must instantiate the same conscious state. Obviously it is possible for two inequivalent computations to instantiate the same state, even computations passing through different sets of states, which is clearly the case in step 3. However, we are being asked to consider two conscious states where the conscious state differs by at least one bit - the W/M bit. Clearly, by the YD assumption, both states are survivor states from the original conscious state, but are not the same consciousness because of the single bit difference. >From this construction, FPI follows. It doesn't depend on the notion of personal identity, interesting though that discussion is. -- ---------------------------------------------------------------------------- Dr Russell Standish Phone 0425 253119 (mobile) Principal, High Performance Coders Visiting Senior Research Fellow hpco...@hpcoders.com.au Economics, Kingston University http://www.hpcoders.com.au ---------------------------------------------------------------------------- -- You received this message because you are subscribed to the Google Groups "Everything List" group.
