Atheist's wager

The Atheist's wager, coined by the philosopher Michael Martin and published in his 1990 book Atheism: A Philosophical Justification, is an atheistic response to Pascal's wager regarding the existence of God.

One version of the Atheist's wager suggests that since a kind and loving god would reward good deeds – and that if no gods exist, good deeds would still leave a positive legacy – one should live a good life without religion. This argument assumes that if a god exists, they are benevolent and just, rather than arbitrary or punitive in their judgment of human actions. This contrasts with Pascal's wager, which presumes a god who rewards belief and punishes disbelief regardless of moral conduct. Philosophers such as John Schellenberg have argued that a perfectly just deity would be more likely to reward sincere moral behavior and intellectual honesty rather than belief for its own sake. Another formulation suggests that a god may reward honest disbelief and punish a dishonest belief in the divine.
