No deep and strong feeling, such as we may come across here and there in the world, is unmixed with compassion. The more we love, the more the object of our love seems to us to be a victim.
We conceal it from ourselves in vain - we must always love something. In those matters seemingly removed from love, the feeling is secretly to be found, and man cannot possibly live for a moment without it.
It's this simple law, which every writer knows, of taking two opposites and putting them in a room together. I love anything with Cartman and Butters at the same time, it's great.
