Pourquoi "hurluberlu"? Expliquez-moi ce mot (en anglais), s'il vous plait. (Je ne parle pas francais!) > > Sorry to break it to you, but you do.

If you believe there's a UD, you believe there's a UD. If not, stop sounding like you do and tell us in plain "anglais" what you mean. I am sure the distinction is totally irrelevant. Math is math. In any case, you either believe that it implements the computations, or you believe that it doesn't. If the latter, then it certainly can't be a candidate for any kind of TOE. >At least you don't believe (unless you change your mind) in the >1-person/3-person distinction, so I don't need even to try >explaining my way, do I? The "third person view" is fully capable of describing the entire situation. (Notice that _I_ never use the term "3rd person view"; a better term would be "actual situation".) Anything an observer-moment sees is just a property of his observer-moment. The measure distribution predicts everything (to the extent possible); one can look at conditional effective probabilities by holding some property of an observation fixed. (Such as "the observer thinks his name is Jack and that the time is 10:00 pm".) Simple. Forget your "first person probabilities" crap, it doesn't mean anything. By the way, "computational continuation" is also meaningless undefined crap. A computation either halts or doesn't; in either case the only continuation is that it either halts or doesn't. It seems to me that I need to repeat myself a lot here. Hey, what's the french word for "crap"? I bet it would sound much more elegant ... unless the french just stole it. - - - - - - - Jacques Mallah ([EMAIL PROTECTED]) Physicist / Many Worlder / Devil's Advocate "I know what no one else knows" - 'Runaway Train', Soul Asylum My URL: http://hammer.prohosting.com/~mathmind/ _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com
