Plantinga's Free Will Defense

Philosophy of Religion

The free will defense is Alvin Plantinga's response to the logical problem of evil, the claim advanced by philosophers such as J.L. Mackie that the existence of evil is logically incompatible with a God who is omnipotent, omniscient and wholly good. Plantinga argues that Mackie never established an explicit contradiction between these claims, since omnipotence means only the power to do what is logically possible, and it is not logically possible even for God to guarantee that genuinely free creatures always choose rightly. He introduces the idea of transworld depravity, the possibility that every possible free creature would go wrong at least once in any world in which it exists, to argue that a world containing free creatures who sometimes do evil may be the best God could actualize while still leaving them free. The defense does not claim to identify God's actual reason for permitting evil, only to show that God's existence is logically compatible with the evil the world contains, shifting the burden onto anyone who claims otherwise to supply the missing premise needed to complete the contradiction.

Does Plantinga's free will defense claim to identify God's actual reason for permitting evil?

No. Plantinga argues only that God's existence is logically compatible with the evil the world contains, using the idea of transworld depravity to show a contradiction was never established; he does not claim to know why God actually allows evil.
