Pascal's Wager
Pascal's wager is Blaise Pascal's famous argument that belief in God is justified as a "good bet", regardless of any metaphysical uncertainty, because disbelief has great cost if wrong, while belief if wrong costs nothing. Pascal's wager suffers from the logical fallacy of false dilemma, relying on the assumption that the only possibilities are that the Christian God exists or that no God exists. The wager cannot rule out the possibility that there is a God who instead rewards skepticism and punishes blind faith, for example. Variations of this argument can be found in other religious philosophies, such as Hinduism. In his own time, Pascal was severely criticized by Voltaire.
/Talk: If I were someone like Pascal, and needed a critic to fortify my position, Voltaire would be an excellent choice. He died a horrible death, screaming that he was wrong about God, and that the flames of hell were reaching for him before he could even finish dying. The cause of his death was a result of his lifestyle, which was, of course, Godless and pleasure seeking. How interesting that you would choose him (Voltaire) to prove Your point.
