Blaise Pascal was a 17th century French philosopher, mathematician, and physicist. He invented a mechanical calculator, and a modern computer programming language is named after him. His contributions had long-lasting impact in the fields of gambling theory, economics, and actuarial science. He was also a deeply religious man. His Pensées, an ambitious work meant to provide a thorough defense of Christianity, were unfinished at the time of his death. The most famous idea to emerge from his draft has been called Pascal’s Wager.

If He does exist, you have everything to gain by believing that He does, and living your life accordingly, and everything to lose by rejecting or ignoring Him. If He does not exist, you have nothing to lose either way. Regardless of what probability you assign to his existence, the rational “wager” is to live as if He does exist.
