In this thought experiment the meaning of the word "I" is not obvious and in fact the entire point of the exercise is supposed to be to make clear exactly what "I" means, and yet you throw out the word as if the meaning is already clear. In one sense there is zero probability because if you became a flying pig you would not be Bruno Marchal anymore. And in some sense there is zero probability the Helsinki man will be the Moscow man because the Moscow experiences is what transformed the Helsinki man into the Moscow man so that although he may remembers being him he is not the Helsinki man anymore. So the answer to the question "If I change what is the probability I will remain the same?" is zero. And that's why I think this first person indeterminacy stuff is just silly. > Comp is just "I can survive with a digital brain".

You claim you have proven that a computer made of matter is not necessary to do a simulation like this but I'll be damned if I can see where you did this. In Aristotle's metaphysics the potential and the actual are somehow one, but is this really true? I don't know. > OK.

You may ask "why are you the Moscow man and not the Washington man?", and my answer is because I received inputs from Moscow not Washington. So a legitimate question and a proper use of probabilities would be "What is the probability I will receive sights and sound from Moscow but not Washington?". Unlike your question this one is perfectly clear and is well suited for statistical analysis, but I don't see what deep philosophical insights can be gained from it. > he know that he will be in W and in M, but he knows that whatever he will > feel to be, it will be in only one place, because he knows that he will not > feel to be in two place at once. > Even that is not a given. This is virtual reality after all, it's the point of your dovetail machine, so there is no reason you couldn't have the White House in the middle of the Kremlin and the Washington Monument right next to St. Basil's Cathedral. > he is aware that he cannot predict which one among the many "he" he will > feel to be. > That is true ONLY if he does not know if he will receive signals from Washington or Moscow, if he knew that, and there is no reason in theory he could not, then he could make such a prediction. > That is the 1-indeterminacy, which is crucial for the rest of the > reasoning. > I know it's crucial, and so if that fails, and it does, then the entire proof falls apart. Don't misunderstand me, I'm not saying your conclusions about numbers are wrong and in fact my hunch is that they are probably right or close to it, but I don't think you've proved it and I'm certain this 1p indeterminate stuff is a dead end. > There is no difficulty.

Forest Gump had a similar explanation that was every bit as deep, "Life is like a box of chocolates...you never know what you're gonna get". >> Non-comp may not be contradictory but all the human practitioners of >> non-comp most certainly are, every single one, no exceptions. >> > > > Many are, but why all, and why necessarily? > All non-comp fans say that knowing what someone or something does is not enough to determine if it is conscious, you need to know HOW they do what they do; and yet until very recently nobody had the slightest idea how the brain worked and yet they still firmly believed that their fellow human beings were conscious when they acted as if they were, that is to say when they were not sleeping or dead. Even today 99.9% of the human population thinks that how the brain works is so unimportant that they have not bothered to learn the first thing about it and are no more informed on the subject than a medieval alchemist, and yet they still insist that how the brain does what it does is far more important than what it does.

If you want to talk about something that is responsible for our existence but is not a person then that's fine, I do it all the time myself, but when I do so I don't use the word "God" because I believe the purpose of language is communication and thus I believe that a language known only to me is of no use to anyone. There are about 900,000 words in the English language and I'm sure you can find at least one of them that describes Arithmetic better than "God", however as I said before, many people are willing to abandon the idea of God but for reasons I don't understand they are unwilling to abandon the word "God". >> Arithmetic is not a person, super or otherwise. >> > > > Arithmetical truth?

There are a enormous number of other things that call themselves John K Clark, some of them very similar to the thing that is writing this Email and others radically different (including one that is now Pope) but all of them see at least some order in their past. It is true that there are a even larger number of paths that have no order whatsoever, no rhyme or reason; and at the end of one of those paths if there were a being looking back he would indeed see nothing but white noise, but there is no being there to look back, because although a little randomness is helpful to Evolution in producing intelligence, random mutation is only half the story, the other half is nonrandom natural selection. So if looking back I saw nothing but white noise I would not be around to look back. John K Clark -- You received this message because you are subscribed to the Google Groups "Everything List" group.
