Pascal's Wager [View all]
https://en.wikipedia.org/wiki/Pascal%27s_Wager
The Wager uses the following logic (excerpts from Pensées, part III, §233):
God is, or God is not. Reason cannot decide between the two alternatives.
A Game is being played... where heads or tails will turn up.
You must wager (it is 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.
But some cannot believe. They should then 'at least learn your inability to believe...' and 'Endeavour then to convince' themselves.
Let's see how Pascal's Wager changes when we add the information that there is not one religion but multiple religions.
God is, or God is not. Reason cannot decide between the two alternatives. (From a mathematical/philosophical point of view, this is correct. As we cannot define God, we cannot reason whether he exists or not.)
A Game is being played... where heads or tails will turn up.
You must wager (it is not optional).
Let us weigh the gain and the loss in wagering that you choose to worship the correct God. Let us estimate these two chances. If you choose correctly, you receive whatever reward religion bestows upon a faithful believer. If you choose incorrectly, you receive whatever punishment religion bestows upon the heathen and heretic.
Wager, then, without hesitation to not worship Him at all. There is an infinity of possible Gods to worship but the number of Gods you worship is finite. And so our proposition is of infinite force, when there is infinitely many ways to err and be punished and finite ways to choose correctly and be rewarded.
But some prefer to believe. They should then 'at least learn your ability to reason...' and 'Endeavour then to convince' themselves.
