How can the Helsinki man be at 2 places at once? BECAUSE HE HAS BEEN DUPLICATED. But they now hold different views on where they are, what are the consequences of that? The Helsinki man differentiates into two, the Moscow man and the Washington man; although both are still the Helsinki man, at least in the same way that although you Bruno Marchal have changed from what you were yesterday, you Bruno Marchal of today are still the man you were yesterday. And the point in space your body was in yesterday or today is not relevant to the question at hand. > you confuse an intellectual hybrid of your 1-you with the set {3-you in > M, 3-you in W}, > The only thing this homemade gobbledegook achieves is confusion, mostly to yourself. > By definition of first person (content or sequence of content of the > diary) > Then I (the original John K Clark or the copy, there is no way for me to tell the difference) share the same "first person" (whatever the hell that is) with the person who just materialized in front of me in the duplicating chamber, because the diary I'm holding looks just like the one that other fellow is holding, and I can vividly remember writing every single line of that diary and he says he remembers doing that exact same thing too. > You seem to continue to oscillate between there is no 1-indeterminacy, > because ... 100% for Moscow, and there is an indeterminacy (but it is > trivial, nothing new). > There is rock stability and no oscillation whatsoever; Indeterminacy is always with us, in the real world thanks to deterministic chaos, in physics thanks to Heisenberg and even in pure mathematics thanks to Godel and Turing, but your complications do not add any more because no matter how convoluted you make them as long as you make clear who "I" and "you" and "he" is your additional probabilities always boil down to 0% or 100%. And if you don't make it clear then everything is meaningless. John K Clark -- You received this message because you are subscribed to the Google Groups "Everything List" group.
