Waterman,
- It looks backwards to establish the probability of an hypothesis, given that a certain event has occurred. We're not trying to establish the probability of an event; we're trying to establish the probability of the hypothesis, given new information.

Aah, I have learned something new. So to simplify an example. I know that Bob is rolling either a die with 6 sides (d6) or a die with 20 sides (d20).
Bob rolls a 5. This has a probability of 1:6 on a d6 and 1:20 on a d20
It is more likely that to be a d6 than a d20. The second roll is a 4. This increases the likelihood that it is a d6 but a d20 is still possible. The 3rd roll is a 7 that eliminates the d6 option it is 100% the d20 regardless of what the odds were after roll two.
I am sure there are formula for this but that is not really relevant yet. Before this can be applied a clear understanding of the relative probabilities if the two hypothesis is required.
What you have appear to have done is to declare that one of the hypotheses is impossible prior to putting it into the equation. Therefore stacking the deck in favor of the perferred hypothesis regardless of how unlikely.
So Bayes cannot be applied until a reasonable probability can be established for BOTH hypotheses. Current scientific theory is that a normally functioning human brain will have the property of self awareness and sense of continuity and growth.
If a healthy human brain exists the odds that it will have a property of self is 1:1. Do you disagree?
