Until today I'd never heard of Epicurus but I was intrigued by this quote which is attributed to him:
“The gods can either take away evil from the world and will not,
or, being willing to do so, cannot;
or they neither can nor will,
or lastly, they are both able and willing.
If they have the will to remove evil and cannot, then they are not omnipotent.
If they can, but will not, than they are not benevolent.
If they are neither able nor willing, then they are neither omnipotent nor benevolent.
Lastly, if they are both able and willing to annihilate evil, why does it exist?”
I love questions which can't be answered. I'm amused by those who feel that such questions have been answered and disgusted by people who are frightened by the questions. I'm content to say "I don't know" but that doesn't mean I'll stop trying to reason out an answer.
