Among the faults of Pascal’s Wager is an oft-overlooked stumper. Pascal proposed a hypothetical reality and then calculated “odds” based on that reality. This is certainly fine for philosophical musing, but the very act of making the proposition gives others the same permission:
Christian: If God is real, then it’s better to have faith, (IF reality is the way Pascal proposed it)
The bold parenthetical is the part Christians don’t include, but which properly belongs in the proposition. An interlocutor may follow their proposition with this:
Atheist: If God is real, then it’s better NOT to have faith, (IF reality consists of a God who rewards skepticism and punishes blind faith.)
Perhaps there is a god, and the Bible, the Koran, and all other holy books were given to us as tests of our reason. Maybe only the humans with strong wills and good reasoning skills are worthy of eternal reward, since it takes real guts to stand up to a threat as terrible as hell, and real intellectual integrity to look at 75% of your peers and say, “The evidence suggests strongly that you are wrong.”
Maybe God’s heroes are Galileo, Copernicus, Dawkins, and Harris. Maybe he takes great joy in sending Pat Robertson, Jerry Fallwell, and George W. Bush to hell as punishment for their blind faith.
Pascal can be used against Christians as easily as it can be used for. It’s still just a thought exercise, and doesn’t carry any empirical weight, but it’s worth understanding the hidden premise.
