“If it falls to your lot to be a street sweeper, sweep streets like Michelangelo painted pictures, sweep streets like Beethoven composed music ... Sweep streets like Shakespeare wrote poetry. Sweep streets so well that all the host of heaven and earth will have to pause and say: Here lived a great street sweeper who swept his job well.”

“Never forget that everything Hitler did in Germany was legal.”

“Courage is an inner resolution to go forward despite obstacles; Cowardice is submissive surrender to circumstances. Courage breeds creativity; Cowardice represses fear and is mastered by it. Cowardice asks the question, is it safe? Expediency ask the question, is it politic? Vanity asks the question, is it popular? But conscience ask the question, is it right? And there comes a time when we must take a position that is neither safe, nor politic, nor popular, but one must take it because it is right.”

“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.”

“As if the weight of such a commitment to life and health of America were not enough, another burden of responsibility was placed upon me in 1964; and I cannot forget that the Nobel Peace Prize was also a commission, a commission to work harder than I had ever worked before for the brotherhood of man. This is a calling that takes me beyond national allegiances.”

“If we look at our history with honesty and clarity we will be forced to admit that our federal form of government has been, from the day of its birth, weakened in integrity, confused and confounded in its direction, by the unresolved race question. It is as if a political thalidomide drug taken during pregnancy caused the birth of a crippled nation.”

“«La oscuridad no puede conducirte fuera de la oscuridad: sólo la luz puede hacer eso. El odio no puede conducirte fuera del odio; sólo el amor puede hacer eso»”

“The hope of a secure and livable world lies with disciplined nonconformists, who are dedicated to justice, peace, and brotherhood. The trailblazers in human, academic, scientific, and religious freedom have always been nonconformists. In any cause that concerns the progress of mankind, put your faith in the nonconformist!”

“There comes a time when silence is betrayal.”

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

“no labor is really menial unless you’re not getting adequate wages.”

“A man who does not have something for which he is willing to die is not fit to live.”

“We must accept finite disappointment, but never lose infinite hope.”

“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.”

“time itself is neutral; it can be used either destructively or constructively. More and more I feel that the people of ill will have used time much more effectively than have the people of good will. We will have to repent in this generation not merely for the hateful words and actions of the bad people but for the appalling silence of the good people. Human progress never rolls in on wheels of inevitability; it comes through the tireless efforts of men willing to be co-workers with God, and without this hard work, time itself becomes an ally of the forces of social stagnation. We must use time creatively, in the knowledge that the time is always ripe to do right. Now is the time to make real the promise of democracy and transform our pending national elegy into a creative psalm of brotherhood. Now is the time to lift our national policy from the quicksand of racial injustice to the solid rock of human dignity.”
