Blaise Pascal (1623-1662) was a French philosopher theologian mathematician and physicist who said humans bet their lives that GOD either exists or does not exist.
His view was that a rational person should live as if GOD exists and seek to believe in HIM.
If GOD does not exist such person will have a finite loss(some pleasures or luxuries) whereas if GOD does exist the person stands to receive infinite gains (Heaven) and avoid infinite loss (eternity in HE**).
"That wager broke ground for probability theory, decision theory, existentialism pragmatism and voluntarism" allegedly. So it's a gamble. Why not gamble on the side of what will benefit you most? WHAT COULD IT HURT? WHO WOULD BE HARMED".
The result of that question caused so much aggravation to a lot of people. I didn't understand why it did so I thought I'd run it up the flagpole again and see what happens.
