I posted a link to an amusing attack on Pascal’s Wager a little while back, but I want to spend some time on the more straightforward attacks on it, so that no-one ever mentions the thing again.
The argument:
------------------God exists-----------God does not exist
Theist---------infinite reward----------some constant R
Atheist---------infinite punishment----some constant R
So, as long as there is the slightest chance that God exists, we ought to believe if we are rational agents.
Problems:
There are really more than just two columns on the table. Which God exists? If we’re supposing that one god is logically possible, there’s no reason not to assume that they all are logically possible. And if they all grant infinite rewards to believers and infinite punishment to heathens, which one do we believe in?
What’s this infintiy doing there? Infinity is not a number. And how can a human ever experience an “infinite” reward? Is it a wonderful reward that lasts forever? Well, the human will never actually get an infinite reward - they’ll just get a longer and longer finite one.
Is this really a good reason to believe in God - for want of reward and fear of punishment? It seems like an awfully bad reason to me - and it seems like the sort of reason a just God would disapprove of.
And is this even a good way to make decisions? If we look at the following puzzle, it seems that the calculation underlying Pascal’s Wager is not a good one.

Furthermore, is it right to say that if there is no God, atheism and theism have the same reward? Perhaps the atheist, having spent their life undeluded and following true principles, will have lead a more meaningful and better life.
Lastly, should we assign a nonzero possibility to the existence of God? If said God is logically impossible in some way, then no.
In other words, Pascal’s Wager is a load of bunk. Don’t use it.
