QUOTE : Great advances in religious epistemology have been made in the last generation. Positivistic challenges to the cognitive significance of religious belief are now passé, having been shown to be based on a criterion of meaning that was overly restrictive and self-refuting. Similarly, claims that atheists and theists have differential burdens of proof, so that in the absence of preponderant evidence for theism, the presumption is that atheism is true, are obsolete. The absence of evidence counts against an existence claim only if it were to be expected that the entity, were it to exist, would leave evidence of its existence in excess of that which we have. This debate has moved on to the question of the hiddenness of God. The difficulty of the atheist is to show why the Christian God should not, as the Bible declares, hide himself from certain unbelievers.
