" I do think there is evil. But it is very rare. It is as rare as true goodness. And just as true goodness produces rare saints, true evil produces rare monsters. The rest of us are semi-good, semi-bad, and we live our lives in a kind of half-happy, half-sad daze. We might hope that one sunny morning we find ourselves in the presence of a saint. And we must pray that we do not encounter the monster. "
