3. The Problem of Evil, the Problem of Air, and the Problem of Silence

Abstract

It used to be widely held that evil-which for present purposes we may identify with undeserved pain and suffering-was incompatible with the existence of God: that no possible world contained both God and evil. So far as I am able to tell, this thesis is no longer defended. But arguments for the following weaker thesis continue to be very popular: Evil (or at least evil of the amounts and kinds we actually observe) constitutes evidence against the existence of God, evidence that seems decisively to outweigh the totality of available evidence for the existence of God. In this paper, I wish to discuss what seems to me to be the most powerful version of the "evidential argument from evil." The argument takes the following form. There is a serious hypothesis h that is inconsistent with theism and on which the amounts and kinds of suffering that the world contains are far more easily explained than they are on the hypothesis of theism. This fact constitutes a prima facie case for preferring h to theism. Examination shows that there is no known way of answering this case, and there is good reason to think that no way of answering it will be forthcoming. Therefore, the hypothesis h is (relative to the epistemic situation of someone who has followed the argument this far) preferable to theism. But if p and q are inconsistent and p is (relative to one's epistemic situation) epistemically preferable to q, then it is not rational for one to accept q. (Of course, it does not follow either that it is rational for one to accept p or that it is rational for one to reject q.) It is, therefore, not rational for one who has followed the argument up
