In many discussions across the blogoshere about the existence of God or supernatural entities, the claim is often made that there’s no reason to think that such things exist because there simply is “no evidence”. Those who do think such entities exist are either “delusional” a la Richard Dawkins, or holding such beliefs “without evidence”. In either case, the theist has somehow failed in his or her epistemic duties to retain such beliefs, especially in our modern, scientific world.
But what precisely is the problem? Is it really a case of “no evidence”, meaning that no observation or phenomenon has ever or could ever provide evidence for the existence of God?
If that is what is meant, it would seem to be reasonable to ask for evidence that such a claim is true. But what that evidence would even look like isn’t at all clear. Or maybe what is meant is that there may be some observations that could be seen by some as evidence for the existence of God, but that there are no known principles that can connect that evidence to the conclusion. In its stronger forms, it is added that no one has ever or will ever know of such principles. What evidence there is for such a claim isn’t clear either.
