…if I believe in God and there is no God then I have lost nothing, however if I don’t believe in God and there is a God then I have lost everything, therefore it is rational to believe in God.
The wager poses as a “stand-alone proof” that belief is rational and disbelief is irrational. That may not be its intent or what it can teach, but that is how I read it.
But God would not accept a “fake belief” (“I believe [but I know you aren’t there]”). So some may say the wager really intends to prove that a rational disbeliever should CONSIDER the possibility that God exists.
I think that ALL BY ITSELF the wager does not prove even that one should consider God.
The wager makes some assumptions that might be acceptable even to some atheists. I.e. it assumes that you accept the NOTION of a “God who causes you to lose everything if you don’t believe in Him” (e.g. you don’t think it is a self-contradiction). It assumes you think that belief is by choice, i.e. not something that can’t be helped. But there is one assumption that is different.
THE FATAL ASSUMPTION OF THE WAGER (as I see it)
The wager (AS IT STANDS) has an hidden assumption that you think the existence of God is (at least) POSSIBLE and not absurd (on the basis of SOME other evidence - NOT just mathematical probability such as 50%(exists/doesn’t exist)).
Similar wager that shows what I mean:
Background: I am told by many people that there is an “oddsc”, who is a 2-headed-6-winged-santa-claus. They say that this oddsc will put everyone who doesn’t believe in him by 2 o’clock tomorrow into a coal-bin for the rest of their lives.
Wager: “If I believe in oddsc and there is no oddsc then I have lost nothing, however if I don’t believe in oddsc and there is a oddsc then I have ruined the rest of my life, therefore it is rational to believe in oddsc”
Who would go out to look for an absurd oddsc (in case he is not absurd after all)?
Here’s an argument that a rational man must at least CONSIDER God’s existence:
Belief Lottery
There are two tickets, which do you choose:
continue disbelief - buys either:
…NO GOD: nothing much… OR
…GOD: hell
reconsider belief - buys either:
…NO GOD: nothing much… OR
…GOD: heaven (if you come to believe & obey)
Any rational man would choose to reconsider belief. (So the argument goes)
The problem is (once again) that some atheists think that hell, heaven and <a God who requires you to believe, or else hell> are impossible or absurd. Cross out all the “GOD” consequences, and see what you get.
HOWEVER there is still hope for some form of the wager. The evidence for God seems to speak for itself (to us, and at least to some atheists - I think). Evidence comes from all directions: conscience, scripture (especially the life of a man named Jesus), creation, our hearts, etc. I hope that deep down some atheists think there is a possibility of God that is seen from God’s grace and all things, not from Pascal’s wager itself.
But a very small possibility isn’t going to move all atheists either. There’s a minute possibility that a claimed cancer cure in Timbuktu may actually work. But many rational people may stick with what they know (medicine that sometimes helps), unless more evidence is given.
However some (by God’s grace) may have felt the strong “pull” of God’s evidence. Possibility may have become real hope in, or fear of, a God that one is beginning to see; or eagerness to reflect on an idea that just might be Truth. Possibility may have become a “reverse” kind of doubt – a doubt of one’s own disbelief, pulling a man towards God not away.
But our perception of God’s evidence, and our search for Him, can be hampered by various things: our own unwillingness, self-deception, carelessness, lack of time, the remoteness of “the next life”, etc.
The wager may remind us that if we even suspect that God is real, searching for Him is something we cannot afford to neglect.
POSSIBLE REWORKING OF THE WAGER (expansion)
Have you ever suspected that God may exist, because of the evidence of your heart and other gifts that may be from Him? If you have, don’t stop looking for Him! If God does NOT exist, but you really looked for Him, what great harm will it do? But if God DOES exist, where will you be, at the end of your life? If you did not care to look for Him (and ignored His call), you will never have God, for you did not seek Him – this is called Hell. If you sought God, with all your heart, and followed Him if He was found, you will forever have the God whom you sought – this is called heaven. If you think there may be a God in whom our happiness lies, search Him out! And pray to Him: “God (if you exist) help me”. What harm will it do, if He does not exist; what good may it do if He does?
