(when I say realtime, it's not that the inner time of the conscious moment should be one to one with the external time where that conscious moment is supervening, but that the conscious moment exists at the same time it is running) (as Russel seems to say). Like say when I'm running an actual program (any one, not a "conscious" one if that exist) in a VM with recorded inputs of a previous run... everytime I run it, it is running and instantiated (not just once)... likewise a "conscious" program, under physical supervenience, the conscious moment would be "existing" everytime I run it and not just once. > > How does this undermine physical supervenience?

Multiple realisation does not undermine physical supervenience... what undermine it, is that you're forced to accept (with the movie graph argument) that the consciousness is supervening on the movie + broken gate... which is absurd, and the conclusion is either that physical supervenience is false or computationalism is... Quentin I agree with that... I'm just saying that if you say, under physical supervenience, that running N times the conscious moment does not instantiate it N times, then you simply reject physical supervenience... > > > Bruce > > > -- > You received this message because you are subscribed to the Google Groups > "Everything List" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To post to this group, send email to [email protected]. > Visit this group at http://groups.google.com/group/everything-list. > For more options, visit https://groups.google.com/d/optout. > -- All those moments will be lost in time, like tears in rain.
