Epicurus

After another successful atheist movie night at my house (tonight we watched The God Who Wasn't There) and a vigorous discussion about the personal impact of conversion and the individual (usually intellectual) capacity to undergo the conversion to atheism, this quote from Epicurus came up:

Is God willing to prevent evil, but not able?
Then he is not omnipotent.
Is he able, but not willing?
Then he is malevolent.
Is he both able, and willing?
Then whence cometh evil?
Is he neither able nor willing?
Then why call him God?
