Pascal's Wager (or Pascal's Gambit) is the name for an idea that Blaise Pascal had. He said that it is not possible to prove or disprove that God exists. Therefore, it is better to bet that God exists. If God existed, and the person believed in God, he would be rewarded (with happiness forever); if the person did not believe, he would be punished (with what is called "eternal damnation"). If God did not exist it would make no difference. For this reason, it would be better to believe in God, Pascal said. Indeed, Pascal strongly believed in this ideal.
