Pascal's Wager states that it's better to live as a religious person as:
A) If God exists, you give up earthly pleasure for eternal salvation (+infinity)
B) If God doesn't exist, you still merely gave up earthly pleasure (-1)
If you are not religious:
A) If God exists, you enjoy earthly pleasure but are sentenced to eternal damnation (-infinity)
B) If God doesn't exist, you got to enjoy earthly pleasure (+1)
The biggest payout and lesser loss both rest in being religious.
This isn't an attempt to convert anyone or start fights, just an interesting concept since everyone else already said what I wanted to say (that religion shouldn't make you a better or worse person, that some choose to believe out of fear of death and that is not necessarily harmful, and that it can also have a negative effect on people such as fundamentalists or used to run away from responsability).
There's a big problem with Pascal's wager in that it can be used for literally anything. For example, I will make the statement "If you don't give me all your money, you will suffer for eternity".
A. If I was right, and you give me all your money, you give up earthly pleasure for eternal salvation (+infinity)
B. If I was wrong, and you give me all your money, you merely gave up earthly pleasure (-1)
OR
A. If I was right, and you don't give me all your money, you kept earthly pleasure but got eternal suffering (-infinity)
B. If I was wrong, and you didn't give me all your money, you get to enjoy earthly pleasure(+1)
So are you gonna send me all your money? Only if you're a fucking moron.
Also, pascal's wager can be mathematically disproven if you consider that for any given "good god" who goes by the rules you listed, there's a "bad god" who might want the exact opposite!. Bad god will punish you eternally if you don't enjoy your earthly existence to its fullest.
See, the problem here is it's arbitrary. Pascal's wager is a great example of how human intelligence can be subverted by invoking infinity, a concept alien and terrifying to us. I can tell you to do literally anything, if I say you get infinite reward for it, or you get infinite punishment for not doing it, if you believe me. If I told you to kill yourself in the most horribly painful way possible, you'd do it, because the punishment for not doing it is infinitely worse.
This is one of those areas where I'll say RationalWiki has some decent, logical arguments. Or maybe it's just my bias because they agree with me on this...
The argument that "Well nobody can know there
isn't a god so being an atheist is just as crazy as being sure god is real" is deeply flawed, because you can use that argument again for literally anything.
How do you know there isn't a planet exactly 54 light centuries away from the sun filled completely with clones of myself living out a real life version of fortnight every day? Are you agnostic to that possibility? How could you know that planet doesn't exist?
The more important question is "What evidence do we have that such a planet exists". The answer being "Absolutely none". So because there's no reason to believe it's true, we assume it's not. Otherwise the answer to every question is either "Yes" or "Maybe".
People ask "What evidence do you have for non-existence of god?". I'd say the same evidence that you have for the non-existence of clone fortnight planet. Namely, the complete lack of evidence of its existence.
It gets philosophical from there, basically to have a somewhat representational model of the universe we inhabit, we have to make lots of assumptions. We don't give the same credibility to any random idea, otherwise we'd spend all our time wondering about some speck of dust in another theoretical universe instead of how we're gonna feed ourselves. The only reason to give more credence to "God exists" over "Fortnight clone planet exists" is because one idea has been repeated more. However, that doesn't excuse believing in Judaeo-Christian god over Thor or Vishnu. I never, ever have heard a person say "How can you say you don't believe in Thor, how can you be so sure?"
To be clear, I don't believe in Thor, Vishnu, Fornight clone planet, or Judaeo-Christian god. Also this post got way too long and nobody is going to read it...
