Pascal’s Wager
Pascal’s Wager (or Pascal’s Gambit) is a suggestion posed by the French philosopher Blaise Pascal that even though the existence of God cannot be determined through reason, a person should “wager” as though God exists, because so living has potentially everything to gain, and certainly nothing to lose. It was set out in note 233 of his Pensées, a posthumously published collection of notes made by Pascal in his last years as he worked on a treatise on Christian apologetics.
Historically, Pascal’s Wager, groundbreaking as it had charted new territory in probability theory, was one of the first attempts to make use of the concept of infinity, marked the first formal use of decision theory, and anticipated the future philosophies of pragmatism and voluntarism.
