Pascal's Wager (or Pascal's Gambit) is a suggestion pose 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.
