And the famous Pascal's Wager from here.

In the seventeenth century the mathematician Blaise Pascal formulated his infamous pragmatic argument for belief in God in Pensées. The argument runs as follows:

If you erroneously believe in God, you lose nothing (assuming that death is the absolute end), whereas if you correctly believe in God, you gain everything (eternal bliss). But if you correctly disbelieve in God, you gain nothing (death ends all), whereas if you erroneously disbelieve in God, you lose everything (eternal damnation).
