In the philosophy of religion, the problem of evil is the question of how to reconcile the existence of evil with that of a God who is, in either absolute or relative terms, omnipotent, omniscient, and omnibenevolent (see theism). An argument from evil attempts to show that the co-existence of evil and such a God is unlikely or impossible if placed in absolute terms. Attempts to show the contrary have traditionally been discussed under the heading of theodicy.
