“The words 'bad timing' came to be ghosts haunting our every move in Birmingham. Yet people who used this argument were ignorant of the background of our planning...they did not realize that it was ridiculous to speak of timing when the clock of history showed that the Negro had already suffered one hundred years of delay.”

“The potential beauty of human life is constantly made ugly by man's ever-recurring song of retaliation.”

“Bitterness has not the capacity to make the distinction between some and all. When some members of the dominant group, particularly those in power, are racist in attitude and practice, bitterness accuses the whole group.”

“Injustice anywhere is a threat to justice everywhere.”

“Until a man is nothing, God can make nothing out of him.” 

“Todo hombre debe decidir si caminará a la luz del altruismo creativo o en la oscuridad del egoísmo destructivo. Éste es el juicio. La pregunta más urgente, e ineludible, de la vida es: ¿Qué estás haciendo por los demás?”

“I have a dream! To be free at last! Free at last! Free at last. And if a man has nothing to die for, Then his life is worth nothing.”

“Something is happening in Memphis; something is happening in our world. And you know, if I were standing at the beginning of time, with the possibility of taking a kind of general and panoramic view of the whole of human history up to now, and the Almighty said to me, "Martin Luther King, which age would you like to live in?" I would take my mental flight by Egypt and I would watch God's children in their magnificent trek from the dark dungeons of Egypt through, or rather across the Red Sea, through the wilderness on toward the promised land. And in spite of its magnificence, I wouldn't stop there. I would move on by Greece and take my mind to Mount Olympus. And I would see Plato, Aristotle, Socrates, Euripides and Aristophanes assembled around the Parthenon. And I would watch them around the Parthenon as they discussed the great and eternal issues of reality. But I wouldn't stop there. I would go on, even to the great heyday of the Roman Empire. And I would see developments around there, through various emperors and leaders. But I wouldn't stop there. I would even come up to the day of the Renaissance, and get a quick picture of all that the Renaissance did for the cultural and aesthetic life of man. But I wouldn't stop there. I would even go by the way that the man for whom I am named had his habitat. And I would watch Martin Luther as he tacked his ninety-five theses on the door at the church of Wittenberg. But I wouldn't stop there. I would come on up even to 1863, and watch a vacillating President by the name of Abraham Lincoln finally come to the conclusion that he had to sign the Emancipation Proclamation. But I wouldn't stop there. I would even come up to the early thirties, and see a man grappling with the problems of the bankruptcy of his nation. And come with an eloquent cry that we have nothing to fear but "fear itself." But I wouldn't stop there.”

“The means by which we live have outdistanced the ends for which we live. Our scientific power has outrun our spiritual power. We have guided missiles and misguided men.”

“Violence never really deals with the basic evil of the situation. Violence may murder the murderer, but it doesn’t murder murder. Violence may murder the liar, but it doesn’t murder lie; it doesn’t establish truth. Violence may even murder the dishonest man, but it doesn’t murder dishonesty. Violence may go to the point of murdering the hater, but it doesn’t murder hate. It may increase hate. It is always a descending spiral leading nowhere. This is the ultimate weakness of violence: It multiplies evil and violence in the universe. It doesn’t solve any problems.”

“Darkness cannot drive out darkness: only light can do that. Hate cannot drive out hate: only love can do that.”

“We must condemn those who are perpetuating the violence, and not the individuals who engage in the pursuit of their constitutional rights.”

“What I'm saying to you this morning is that Communism forgets that life is individual. Capitalism forgets that life is social, and the Kingdom of Brotherhood is found neither in the thesis of Communism nor the antithesis of capitalism but in a higher synthesis.”

“The major problem of life is learning how to handle the costly interruptions. The door that slams shut, the plan that got sidetracked, the marriage that failed. Or that lovely poem that didn't get written because someone knocked on the door.”

“On the parable of the Good Samaritan: "I imagine that the first question the priest and Levite asked was: 'If I stop to help this man, what will happen to me?' But by the very nature of his concern, the good Samaritan reversed the question: 'If I do not stop to help this man, what will happen to him?”
