A thesis in moral philosophy

"It sounds like something you'd read on a movie poster: sometimes the sins you haven't committed are all you have to hold on to. If you're really desperate, you might need to grope, saying, for example, 'I've never killed anyone with a hammer' or 'I've never stolen from anyone who didn't deserve it.... [But] I can glimpse at what my life would be like without my [sexual fidelity], of how lost I'd feel without this scrap of integrity, and the fear is enough to wake me up."

--David Sedaris
