Are you saying, here, that it is wrong to factor in the utility of the hypothesis when giving weight to the hypothesis?
No (assuming you mean the expected utility of the action given the hypothesis), just that you have to accurately weight its probability.
If he didn't consider all the cases, his particular application of the argument was bad, not the argument itself, right?
But his argument wouldn't somehow be improved by considering all the cases (not that it would be practical to even consider all the hypotheses of lengths up to that which implies high utility from faith in God!). Considering those cases would find hypotheses that assign the opposite utility to faith, and worse, some would be more probable.
To salvage the argument, one would have to not just consider more cases, but provide a lot more epistemic labor -- that is, make arguments that aren't part of PW to begin with.
All of your objections to PW seem to be about Pascal's application of the argument (the probabilities he inputted, the number of cases cases he considered) in which case we can agree that his conclusion wouldn't be correct.
When I read that Pascal's Wager is flawed as an argument, I interpret this as 'the argument does not have good form'. Did people just mean, all along, that they disagreed with the conclusion of the argument because they didn't agree with the numbers he used?
It has been claimed on this site that the fundamental question of rationality is "What do you believe, and why do you believe it?".
A good question it is, but I claim there is another of equal importance. I ask you, Less Wrong...
What are you doing?
And why are you doing it?
