“God is, or He is not”
A Game is being played… where heads or tails will turn up.
According to reason, you can defend either of the propositions.
You must wager. (It’s not optional.)
Let us weigh the gain and the loss in wagering that God is. Let us estimate these two chances. If you gain, you gain all; if you lose, you lose nothing.
Wager, then, without hesitation that He is. (…) There is here an infinity of an infinitely happy life to gain, a chance of gain against a finite number of chances of loss, and what you stake is finite. And so our proposition is of infinite force, when there is the finite to stake in a game where there are equal risks of gain and of loss, and the infinite to gain.
Ok, so why is this wrong? First, it is based on a false dichotomy fallacy. Which god? People often forget, due to the self-absorbed nature of humanity, that there is more to the world than just what they believe in. Let’s not forget that there are any number of gods that are believed in equally strongly by their respective theists.
Second, if we factor in the existence of multiple gods, we must also factor in the potential punishment of following the wrong god. The first commandment makes it pretty clear that at least some gods don’t like it when you choose the wrong one. Additionally, the game is no longer a wager between two options. You have multiple options, with each option – except atheism – promising reward and punishment.
By now, we’ve pretty much destroyed step one of Pascal’s Wager. If you’re keeping up, you’ll release we’ve destroyed step two as well (it is no longer a 50/50 chance – heads or tails is no longer valid). But wait, there’s more!
