I predicted the guy who saw Moscow would become the Moscow guy and the guy who saw Washington would become the Washington guy, and that is exactly precisely what happened. And don't complain that's a tautology, it's your thought experiment and your question not mine.

And I don't even understand why you're so obsessed with prediction when that has nothing to do with our sense of self, we get that by looking into the past and a good thing too because nobody can look into the future. > > like the prediction “I will see one city”. > And you have no idea who Mr. I is either, not if there are Mr. I duplicating machines. >>I have agreed that if survival today means being able to remember being >> the Helsinki Man yesterday and somebody remembers today then the Helsinki >> Man has survived today.

If you say "both" you can't still demand one and only one answer unless logic means nothing to you. Don't you think the fact that you can't answer the question even AFTER the "experiment" is over is a pretty good indication that it's not a experiment at all and the question makes no sense? > >*the question is about what to expect in Helsinki, given that we know > that there will be two futures, but only one from all first person > experiences accessible from Helsinki.* > If the question was not gibberish you could forget about theories and philosophy and metaphysics and simply perform the experiment and tell me the one and only one city name that turned out to be correct, but you can't do that.

The same for the > Moscow guy.* > Well maybe that's true, maybe the Helsinki man was unable to predict that, but then the Helsinki man is a idiot. I am not a idiot so I could have predicted it. Not that prediction has anything to do with the sense of self. John K Clark -- You received this message because you are subscribed to the Google Groups "Everything List" group.
