One of the most vexing problems in the philosophy of religion is the existence of moral evil in light of an omnipotent and wholly good deity. A popular mode of diffusing the argument from evil lies in the appeal to free will. Traditionally it is argued that there is a strong connection, even a necessary one, between the ability to exercise free will and the occurrence of wrong-doing. Transworld depravity, as characterized by Alvin Plantinga, is a concept which has gone far to explain this relationship. Essentially, the notion of transworld depravity involves the claim that in any world where a person is significantly free that person would, on some occasion, act morally wrongly, or as Plantinga phrases it: ‘If S' were actual, P would go wrong with respect to A’ (where S' is a possible world, P is a person and A is an action). Not only, Plantinga claims, is it possible that there are persons who suffer from transworld depravity, but ‘it is possible that everybody suffers from it’. If transworld depravity obtains, Plantinga notes, God ‘might have been able to create worlds in which moral evil is very considerably outweighed by moral good; but it was not within His power to create worlds containing moral good but no moral evil – and this despite the fact that He is omnipotent’. On this view, God could not instantiate perfect-person essences who would not ever sin. Although Plantinga argues that these instantiated beings are significantly free in that they could have done otherwise (i.e. not sinned), it does seem that his claim about transworld depravity amounts to a claim about transworld depravity amounts to a claim about the existence of a necessary connection obtaining between freedom and evil. For even though it makes sense to claim that an individual may have unactualized dispositions, to claim that everyone, past, present and future, has unactualized dispositions seems to be a significantly different claim. It is therefore difficult to see how this latter claim differs in substance from the claim of a necessary connection obtaining between the capacity for free will and the commission of evil acts.
