"The day we see the truth and cease to speak is the day we begin to die."

"One day we will have to stand before the God of history and we will be asked what did we do with these moments of great moral challenge."

"We shall overcome because the arc of the moral universe is long, but it bends toward justice."

"It is not enough to say we must not wage war. It is necessary to love peace and sacrifice for it."

"Nothing pains some people more than having to think."
