This came up in the midst of a recent discussion of The Problem of Evil. A subject which is actually seen quite regularly on my blog.
"You know if there's no suffering and evil in the world, there'd be no pleasure or good either."
That's bull. I don't need to stub my toe in order to enjoy a good piece of pie. If evil did not exist, we wouldn't necessarily have concepts of "good" or "evil" since it would always be good but I can enjoy good without ever experiencing evil. Just like I can enjoy nice cool weather without ever going through a heat wave.
