Scott Oliphant has written a good piece on God and the problem of evil. Here’s a taste:
“This problem goes back at least as far as Epicurus (342-270 BC), and was set forth by David Hume in his Dialogues Concerning Natural Religion. It is articulated in two, many would say, contradictory propositions:
1. God is omniscient, omnipotent and wholly good.
2. There is evil.
There are two basic ways to argue the inconsistency of these two propositions. The first, and historically most predominant way, is to argue that these two propositions are logically contradictory. This argument is still used by some, but it has given way to the so-called “evidential” argument from evil, and it is an attempt to show that, given the sheer amount of evidence of evil in the world, God, most likely, cannot exist.”
