Pascal's Wager is the French philosopher Blaise Pascal's application of decision theory to the belief in God. It is also occasionally known as Pascal's Gambit. It appears in the Pensées, a posthumous collection of Pascal's notes for an unfinished treatise on Christian apologetics. Pascal argued that it is a better "bet" to believe that God exists, because the expected value of believing that God exists is always greater than the expected value resulting from non-belief. Indeed, he claimed that the expected value is infinite. Pascal believed that it was inexcusable not to investigate this question: "Before entering into the proofs of the Christian religion, I find it necessary to point out the sinfulness of those men who live in indifference to the search for truth in a matter which is so important to them, and which touches them so nearly."
