“Just assume that you don’t know anything – that’s a good place to start from in any situation.”

“Start out the day assuming you know nothing. That’s a good start to the day.”

“Now I pass up about twenty-five or thirty thousand of honest gain because I like being a detective, like the work. And liking work makes you want to do it as well as you can. Otherwise there’d be no sense to it. That’s the fix I am in. I don’t know anything else, don’t enjoy anything else, don’t want to know or enjoy anything else. You can’t weight that against any sum of money. Money’s good stuff. I haven’t anything against it.”

“If you like everything, that’s basically just saying that you don’t really like anything.”

“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.”

“Human behavior is only unpredictable and dangerous if you don’t start from humanity in the first place.”
