“Have I said anything I started out to say about being good? God, I don’t know. A stranger is shot in the street, you hardly move to help. But if half an hour before, you spent just ten minutes with the fellow and knew a little about him and his family, you might just jump in front of his killer and try to stop it. Really knowing is good. Not knowing, or refusing to know, is bad, or amoral, at least. You can’t act if you don’t know. Acting without knowing takes you right off the cliff.”
