Well, likewise with the quantum version. In fact there are two versions of you who can ask them (i.e. if you accept the MWI, what's the problem?) (We seem to have been around in a loop on this about 100 times...)

In other words, all types of existence appear to be equally "Heraclitean" and I'm not sure why Bruno's thought experiment should be treated any differently to the nonduplicated and the quantum-duplicated versions. He's just using it to point out the somewhat disjointed nature of normal existence by putting it into a hypothetical situation where we can more easily think about the consequences. It's all very well having reservations that X might make a difference, but as Bruno keeps saying, show him where he's gone wrong so he can stop worrying about comp and spend his time keeping bees instead! -- You received this message because you are subscribed to the Google Groups "Everything List" group.
