'Tragedy admires man. Comedy feels a bit sorry for him.' We think we are kings or queens, masters of the universe or at least our own destiny. We forget that a foot may crush us, or that the wind may knock us down. We are not in control. We are subject to gas and sloughing skin and dirty pores. Most of our joints will eventually fail us. We have big brains which we can imagine great things, but we can't really get off the ground. It's like we have wings but we can't fly.
