The probability of God’s existence

It seems to me that in the atheism/theism debate, neither side openly professes certainty, for fear that they will look like fundamentalists. If neither side is certain, then nobody can back up their view with real conviction. Let’s look at it this way. If someone were to tell you that object x exists, but that nobody in the world has seen it, your first inclination would be to doubt it, especially if the object has such extraordinary qualities that it would be very surprising if it was even possible to exist. However, you couldn’t say, x definitely doesn’t exist. The most you can say is that it probably doesn’t exist. But how do you accurately assess probabilities in such cases? Given that there are an infinite number of things that x could be, one would have to conclude that the probability, in this grand scheme, that x exists, is very low. As far as we know, God is as likely to exist as a unicorn.

But there are other things that we haven’t seen, yet we have reason to believe exist. The reason we believe that black holes are likely to exist is that they are postulated as a result of calculations which, as far as we know, are correct. There is no equivalent for God. There is no calculation which says the universe must have been consciously created. Scientific endeavour hasn’t led us to a definite conclusion about the beginning of the universe, but the evidence leads us further and further away from conscious creation.

In a world in which the idea that some unseen x might possibly exist is taken seriously, how are we to treat this x? Certainly, we should not treat it seriously according to how it is defined. If I say that x is a being such that if you don’t believe in its existence, you will suffer an eternity of pain (and that is its only property), again you will be disinclined to believe. There could be another being called y which has the property that if you believe in x, you will suffer an eternity of pain. How can you know which to believe in? They are equally likely to exist, and neither x nor y has any presence in our lives in any meaningful way, other than that we are told that they exist by people who have never seen them.

That is the reason why, despite a lack of evidence (if such a thing could ever be produced) that God doesn’t exist, there is no reason to believe. One’s life might be different if the idea of God was removed, but not if God himself were gone.

The trouble with prophets

This house believes that if someone were to claim to be a prophet nowadays, they would be roundly mocked by most of the very people who follow prophets of their own, and followed only by desperate or crazy people. Perhaps this says something about the first followers of the great world religions?
