The Ballot or the Bullet (1964), Speech in Cleveland, Ohio (April 3, 1964)
Context: And now you’re facing a situation where the young Negro’s coming up. They don’t want to hear that "turn the-other-cheek" stuff, no. In Jacksonville, those were teenagers, they were throwing Molotov cocktails. Negroes have never done that before. But it shows you there’s a new deal coming in. There’s new thinking coming in. There’s new strategy coming in. It’ll be Molotov cocktails this month, hand grenades next month, and something else next month. It’ll be ballots, or it’ll be bullets. It’ll be liberty, or it will be death. The only difference about this kind of death—it’ll be reciprocal.

Interview on National Public Radio (13 December 1974)
Context: I think politicians and movie actors and movie executives are similar in more ways than they’re different. There is an egocentric quality about both; there is a very sensitive awareness of the public attitude, because you live or die on public favor or disfavor. There is the desire for publicity and for acclaim, because, again, that’s part of your life... And in a strange and bizarre way, when movie actors come to Washington, they’re absolutely fascinated by the politicians. And when the politicians go to Hollywood, they’re absolutely fascinated by the movie stars. It’s a kind of reciprocity of affection by people who both recognize in a sense they’re in the same racket.

The New York Times interview (2017)
Context: I was never that involved in the machine of press and publicity as an actor because I’ve always kind of worked on the margins of my profession … And then when my son was younger and it did get a little bit more intrusive, I tried to come to terms with how I was personally going to handle someone coming up to me on the street and wanting some part of my time. … Now what I do — because this is how I live — when someone approaches me and says, "Can I have your autograph," I say: "No, I’ve retired from that part of the business. I just act now." … I say: "What’s your name?" … I touch them. I look at them. I have a real exchange … I’m not an actor because I want my picture taken. I’m an actor because I want to be part of the human exchange.

“Savor kindness because cruelty is always possible later.”

“When you have a good mother and no father, God kind of sits in. It's not enough, but it helps.”
