Dave,
- Just to set the stage:
- In arguing towards an infinite number of potential selves, I had been claiming that combinations of sperm cells and ova from your dad and Cleopatra, respectively, represented potential selves. You said that such would require time travel, which is impossible. I came back with impossible does not preclude potential. You came back with P(me) is 1. I came back with, “There is no P(me) is one in the Bayesian formula.” To which, you came back with, “But to calculate the probability, you still need to look at the conditions at the time of the event occurring.”
...and to calculate the likelihood of that person existing given "A", you need to include all the factors that A says led to her existence.
- But all that A "says" is that each self has only one finite life to live. It doesn't say anything specific about "her," or "me." And "A" is the only given.
- There is nothing in the Bayes formula that deals with the specific factors leading to my, existence. And, we're really asking, "What is the likelihood (in a random universe) that all the factors necessary for leading to my current existence would occur?
- Again, we already know that I exist. What we're looking for is the impact that my current existence has on the truth value of "A." Does my current existence undermine the theory?
The probability of drawing a particular sample from a particular population has mathematical implications re the probability that a particular sample was, in fact, drawn from THAT population... (My own quote -- you might want to read that again.)
- Which leads, I think, to the "other" major issue here (the first issue being the 'number' of potential selves), "Is the likelihood of
my, particular, current existence, given 'A,' the appropriate entry here; or, is the likelihood of
anyone's current existence, given 'A,' the appropriate entry here?
- I know that everyone has been asking me to move on to that issue, but I was hoping to clear up the infinity issue first.
- Hopefully, I’ll be able to organize that better, and get on with the “me” vs “anyone” issue in my next posting.
