“We must forever conduct our struggle on the high plane of dignity and discipline. We must not allow our creative protest to degenerate into physical violence.”

“The richer we have become materially, the poorer we become morally and spiritually. We have learned to fly in the air like birds and swim in the sea like fish, but we have not learned the simple art of living together as brothers.”

“Our only hope lies in our ability to recapture the revolutionary spirit and go into a sometimes hostile world declaring eternal hostility to poverty, racism, and militarism”

“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 consistently preached that nonviolence demands that the means we use must be as pure as the ends we seek. I have tried to make clear that it is wrong to use immoral means to attain moral ends. But now I must affirm that it is just as wrong, or perhaps even more so, to use moral means to preserve immoral ends.”

“If there is to be peace on earth and good will toward men, we must finally believe in the ultimate morality of the universe, and believe that all reality hinges on moral foundations.”

“I have almost reached the regrettable conclusion that the Negro's great stumbling block in his stride toward freedom is not the White Citizen's Counciler or the Ku Klux Klanner, but the white moderate, who is more devoted to "order" than to justice; who prefers a negative peace which is the absence of tension to a positive peace which is the presence of justice; who constantly says: "I agree with you in the goal you seek, but I cannot agree with your methods of direct action"; who paternalistically believes he can set the timetable for another man's freedom; who lives by a mythical concept of time and who constantly advises the Negro to wait for a "more convenient season.”

“And one day we must ask the question, "Why are there forty million poor people in America?" And when you begin to ask that question, you are raising questions about the economic system, about a broader distribution of wealth. When you ask that question, you begin to question the capitalistic economy.”

“And in every one of us, there's a war going on. It's a civil war. I don't care who you are, I don't care where you live, there is a civil war going on in your life. And every time you set out to be good, there's something pulling on you, telling you to be evil. It's going on in your life. Every time you set out to love, something keeps pulling on you, trying to get you to hate. Every time you set out to be kind and say nice things about people, something is pulling on you to be jealous and envious and to spread evil gossip about them. There's a civil war going on. There is a schizophrenia, as the psychologists or the psychiatrists would call it, going on within all of us. And there are times that all of us know somehow that there is a Mr. Hyde and a Dr. Jekyll in us...There's a tension at the heart of human nature. And whenever we set out to dream our dreams and to build our temples, we must be honest enough to recognize it.”

“we must constantly build dykes of courage to hold back the flood of fear”

“Science investigates, religion interprets. Science gives man knowledge which is power, religion gives man wisdom which is control. Science deals mainly with facts, religion deals with values. The two are not rivals. They are complementary. Science keeps religion from sinking into the valley of crippling irrationalism and paralysing obscurantism. Religion prevents science from falling into the marsh of obsolete materialism and moral nihilism.”

“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.”

“Individuals may see the moral light and voluntarily give up their unjust posture; but... groups tend to be more immoral than individuals.”

“And you know, it's possible that the priest and the Levite looked over that man on the ground and wondered if the robbers were still around. Or it's possible that they felt that the man on the ground was merely faking. And he was acting like he had been robbed and hurt, in order to seize them over there, lure them there for quick and easy seizure. And so the first question that the Levite asked was, "If I stop to help this man, what will happen to me?" But then the Good Samaritan came by. And he reversed the question: "If I do not stop to help this man, what will happen to him?”

“Returning hate for hate multiplies hate, adding deeper darkness to a night already devoid of stars. Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate, only love can do that.”
