The Argument from Pascal's Wager
Excerpt: Most philosophers think Pascal's Wager is the weakest of all arguments for believing in the existence of God. Pascal thought it was the strongest. After finishing the argument in his Pensées, he wrote, "This is conclusive, and if men are capable of any truth, this is it." That is the only time Pascal ever wrote a sentence like that, for he was one of the most skeptical philosophers who ever wrote.
Suppose someone terribly precious to you lay dying, and the doctor offered to try a new "miracle drug" that he could not guarantee but that seemed to have a 50-50 chance of saving your beloved friend's life. Would it be reasonable to try it, even if it cost a little money? And suppose it were free—wouldn't it be utterly reasonable to try it and unreasonable not to?
Blaise Pascal was a devout Christian and very influential French mathematician and philosopher who contributed to many areas of mathematics. He worked on conic sections and projective geometry and in correspondence with Fermat he laid the foundations for the theory of probability as well as laid the foundation for the science of hydraulics.
