Philosophers have looked for ways to explain God's existence for centuries.
One such argment that the believer must justify in order to maintain the possibility of God's existence is the problem of evil. In his essay, "The
Problem of Evil," by Richard Swinburne, the author attempts to explain how evil can exist in a world created by an omniscient, omnipotent, omnibenevolent Being, namely God. Swinburne uses to free-will defense and says that God gave us a choice between doing good and doing evil. If someone chooses to do good over evil, then that Good is greater than if one had no choice at all but to do good. This is a weak argument and in order to clarify those weaknesses one can look at Steven M. Cahn's essay entitled "Cacodaemony." This essay parallels
Swineburne's, but states that an omniscient, omnipotent, omnimalevolent Demon created the world. By looking at how weak the argument for cacodaemony is, one can see how unlikely it is that the Demon exists and then can see that the existence of God is just as unlikely. In "The Problem of Evil", Swinburne says that an omniscient, omnipotent, omnibenevolent Being created the world. If this were true, how can evil exist in this world? If God consciously knew He was creating a world in which there is evil, then He would not be omnibenevolent. If God did not know He was creating a world in which evil exists, then He would not be omniscient. If God is omnipotent then He would be able to stop any evil from occurring. Either way,
God would not be what Christianity makes him out to be. Swinburne argues that the theodicist, one who believes that it is not wrong for God to create a world in which there is evil, can logically explain the existence of evil in the world.
The main argument that the theodicist uses is the free-will defense, which claims that God gave humans the freedom to choose between doing acts of good and acts of evil.
