“The problem of evil is unanswerable if one believes that there is only one god and that he is omnipotent as well as infinitely good, merciful, and just. But as soon as one denies one or more of these premises, the problem disappears. The belief in two great gods, one good and one evil, is merely one way of doing that. Polytheism is another. Belief in only one god who is omnipotent but not infinitely good, just, and merciful is a third way. Belief in a god who has these moral qualities but who is not omnipotent is a fourth. Belief in no god at all, a fifth.”
