The illusion of a flow of time is created by the fact that subjectively later OM's remember subjectively earlier OM's. Today is Tuesday, and I remember yesterday, which was Monday, and look forward to tomorrow, which will be Wednesday. It could be that in real time, Wednesday occurred yesterday and Monday will occur tomorrow, but this can make no subjective difference to me experiencing the illusion of continuity from one day to the next. Even if a trillion copies of the Monday me are run tomorrow, that cannot possibly cause me to wake up in my subjective future and find, to my great surprise, that it is Monday rather than Wednesday. Or to put it differently, I *will* wake up tomorrow (per real time) and find that it is Monday, but that version of me will have no memory of Tuesday, whereas the Wednesday version of me that was actually run yesterday will have this memory. The subjective temporal ordering of experience has nothing to do with the actual temporal ordering of OM's and will also occur in the absence of any actual temporal ordering, i.e. in a block universe. Only OM's with a particular content are candidates for inclusion in my subjective future. Of those candidates, which one I will experience depends on their relative measure. > Does this mean that you disagree with the notion that > we can draw conclusions (a la Bostrom) about measure from the OM we > happen to be experiencing?

The self-sampling assumption is useful if I am trying to guess what group I am in. If I don't know whether it is Monday or Tuesday but I know that there are a trillionfold as many copies of the Monday me, then I should bet on it being Monday. But if I already know that it's Tuesday, then the probability that it is Monday is zero and the probability that I will experience Monday in the future is also zero. You might say that it very unlikely that it would be Tuesday if there are a trillionfold as many Monday copies, but we come up against this all the time in everyday life. It is far more likely that a person will be born in China than in Lichtenstein, but given that he was born in Lichtenstein, he stays born in Lichtenstein. -- Stathis Papaioannou --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Everything List" group.
