Pascal’s Wager is an argument in apologetic philosophy devised by the seventeenth-century French philosopher, mathematician and physicist Blaise Pascal. It posits that humans all bet with their lives either that God exists or that he does not. Pascal argues that a rational person should live as though God exists and seek to believe in God. If God does actually exist, such a person will have only a finite loss (some pleasures, luxury, etc.), whereas they stand to receive infinite gains (as represented by eternity in Heaven) and avoid infinite losses (eternity in Hell).
Hedging one’s bets in such a cowardly way is one way to waste one’s life.
