Pascal's Wager

From The Encyclopaedia Expurgatia

An illconceived reasoning designed to promote catholicism, Pascal's Wager essentially suggests that: to believe in a given deity, and to be wrong, is to be out nothing; to decline to believe in said deity, and to be wrong, is to be out everything.

Pascal's Wager fails against multiple variables, though: to believe in a given deity, which doesn't exist, thus angering a given deity, which does, is to be in far more trouble than any atheist.

Pascal's Wager hasn't been successfully used since about the time that the Earth was found not to be flat.
