“Rarely do we find men who willingly engage in hard, solid thinking. There is an almost universal quest for easy answers and half-baked solutions. Nothing pains some people more than having to think.”

“The time comes when silence is betrayal. That time has come for us today...  ...some of us who have already begun to break the silence of the night have found that the calling to speak is often a vocation of agony, but we must speak.”

“If a man is called to be a street sweeper, he should sweep streets even as Michealangelo painted, or Beethoven composed music, or Shakespeare composed poetry. He should sweep streets so well that all the hosts of heaven and earth will pause to say, “Here lived a great street sweeper who did his job well.”

“You are not only responsible for what you say, but also for what you do not say”

“As he continued, one could see obvious disappointment on the faces of the white committee members. By trying to convince the Negroes that I was the main obstacle to a solution they had hoped to divide us among ourselves. But Ralph’s statement left no doubt. From this moment on the white group saw the futility of attempting to negotiate us into a compromise.”

“...we are always on the verge of being mesmerized by uncertainty; but we must move on.”

“Every man must decide whether he will walk in the light of creative altruism or in the darkness of destructive selfishness.”

“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.”

“The soft-minded man always fears change. He feels security in the status quo, and he has an almost morbid fear of the new. For him, the greatest pain is the pain of a new idea.”

“On some positions, Cowardice asks the question, “Is it safe?” Expediency asks the question, “Is it politic?” And Vanity comes along and asks the question, “Is it popular?” But Conscience asks the question, “Is it right?”... The ultimate measure of a man is not where he stands in moments of convenience, but where he stands in moments of challenge, moments of great crisis and controversy.”

“Ik raakte ervan overtuigd dat niet meewerken aan een slechte zaak net zo goed een morele verplichting inhoudt als meewerken aan iets goeds.”

“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.”

“But today our very survival depends on our ability to stay awake, to adjust to new ideas, to remain vigilant and to face the challenge of change. The large house in which we live demands that we transform this world-wide neighborhood into a world – wide brotherhood. Together we must learn to live as brothers or together we will be forced to perish as fools. We must work passionately and indefatigably to bridge the gulf between our scientific progress and our moral progress. One of the great problems of mankind is that we suffer from a poverty of the spirit which stands in glaring contrast to our scientific and technological abundance. The richer we have become materially, the poorer we have become morally and spiritually.”

“All too many others have been more cautious than courageous and have remained silent behind the anesthetizing security of stained-glass windows”

“The time is always right, to do what's right.”
