Three problems with Pascal's Wager:

1) It is logical, too logical, as it turns out. If the idea is to prove by compelling logic that you would do well to believe in god, a positive hypothetical, then you should believe in every positive hypothetical similarly formulated. Such as the Evil Easter Bunny, who will chew you to bits for eternity if you don't believe in him. Might as well believe in him too, right? Along with wizards, lawn gnomes, Apollo, etc. You've got the same to lose if you don't.

2) Which god or gods do I wager on?

3) Most of the gods I know of allegedly want you to believe in him because he loves you and you love him, not because you solved an elementary problem of logic.
