Lewis on Free Will and Suffering

'Try to exclude the possibility of suffering which the order of nature and the existence of free-wills involve, and you will find that you have excluded life itself.'"

C.S. Lewis in The Problem of Pain

Epicurus poem on God and evil

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?
-- Epicurus"
