Fig. 1. Payoff matrix for Pascalís wager. There are two possible states of reality (God exists or not), and two possible actions (wager for or against God). Each element of the matrix reflects the payoff, or utility, corresponding to a possible situation. A wager for God yields an infinitely positive utility, if God exists. In all other cases, the utility is either finite, or possibly negative infinity for a wager against an existent God.
