As Clavius states in the movie Risen what his greatest fear is: "Being wrong, and wagering eternity on it."
The main objections most people have to Pascal's wager never seemed to cut it for me.
The first objection, which Pascal himself simply laughed at as a word game, is that there are multiple religions with different gods and to follow one religion faithfully would mean violating the tenants of other religions, all of which have infinite consequences. This objection is false, and obviously so, because there really are only two religions with infinite consequences – Christianity and Islam – and the two are mirror opposites of one another. And if you need help figuring out which is which then you're hopeless and shouldn't be pursuing philosophy.
The second objection argues that God would never accept someone who is persuaded by the wager because such a person is being moral for selfish reasons. This objection, too, has been transformed into a joke by the anti-Christians, because the only people opposing Pascal very rarely talk about other religions, which always seemed suspicious to me, as if their primary objective was just anti-Christian. They are not atheists because none of them seem to oppose the infusion of paganism into modern society, like all the days of the week and the months being named after pagan deities (and yes, there are many thousands of people who profess belief in Odin and nature spirits and all of that, so the argument that these are dead religions falls flat). And very few of them ever dare criticise Islam, and most actively praise it. Let's face it, if the money said "In Thor We Trust" or "In Allah We Trust" none of these so-called atheists would complain. Their only problem is with Christianity because it gives them the out to be edgelords.
Atheists seem to be saying that God, or at least the Christian God, would endow humans with the faculties of reason and intelligence and then demand that we never use them. The God of the objectors wants humans to be stupid, based on the false notion that faith means "belief without evidence", when, in actuality, faith in the Biblical context means something closer to trust, and is arrived at through reason and evidence.
Stupid people, overwhelmingly it seems, are not moral. Certainly not more moral than smart people. Stupid people kill albinos because they believe albinos practice sorcery. Stupid people kill others for sorcery, full stop. Stupid people have sex with their cousins and produce inbred children who are even stupider. Stupid people cut open the heads of bald men believing treasure to be inside. Stupid people are less moral because stupid people have lesser ability to defer gratification, which makes them more violent, and stupid people are also less empathetic, meaning less able to take on the perspectives of others. This means that the God of the Anti-Pascalites wants humans to be immoral. If God wants people to be immoral then God is not God but is instead the Devil. The Anti-Pascalites are confusing the Devil for God and are crafting an erroneous argument out of their own confusion.
But God is not the Devil, and God wants people to be moral, because God is moral. If God wants people to be moral then God wants people to be smart. Smart people come to trust God through reason and evidence, and can apply that reason to see that it is better to be moral and believe in God than to be immoral and disbelieve in God. An intelligent person can appreciate Pascal's wager, because morality within a Western context is inextricably linked to Christianity.
This isn't to say that God exists. Pascal was not arguing for the existence of God with his wager, although he did present arguments for the existence of God in the same unpublished book. Pascal was merely saying that it is better to act as if God exists, meaning that it is better to act morally than to not act morally, because the consequences otherwise are too horrific to contemplate.
And we've seen those consequences. We've seen the hundreds of millions dead as a result of societies that have tried to kill God. The consequences go above and beyond survival after death, they impact the world of the here and now. The only thing that can replace God is the absolutist state, and the problem with the absolutist state is that it does not recognise any authority outside of itself. The absolutist state has no room for forgiveness, where as God's mercy is very great indeed. We've seen this with the gulags and the killing fields, and more recently with cultural Marxism and how the left has begun to eat its own. In the great oppression olympics, the left has sought to crucify its own members who are not extreme enough. There is only one place behaviour like this ends, and that's a mass grave.
Whether we want to think of the metaphysical implications or not, the pragmatic implications of cultural Christianity more than justify the continuation and strengthening of Christian culture within Western society.
Atheist Richard Dawkins identifies as culturally Christian.
