“The true measure of a man is not how he behaves in moments of comfort and convenience but how he stands at times of controversy and challenges.”

“Agape does not begin by discriminating between worthy and unworthy people, or any qualities people possess. It begins by loving others for their sakes. It is an entirely “neighbor-regarding concern for others,” which discovers the neighbor in every man it meets. Therefore, agape makes no distinction between friend and enemy; it is directed toward both. If one loves an individual merely on account of his friendliness, he loves him for the sake of the benefits to be gained from the friendship, rather than for the friend’s own sake. Consequently, the best way to assure oneself that love is disinterested is to have love for the enemy-neighbor from whom you can expect no good in return, but only hostility and persecution.”

“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.”

“Unless you have found something in life to live for that is more important to you than your own life, you will always be a slave. For all another man needs to do is threaten to take your life to get you to do his bidding.”

“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.”

“We are now faced with the fact that tomorrow is today. We are confronted with the fierce urgency of now. In this unfolding conundrum of life and history, there "is" such a thing as being too late. This is no time for apathy or complacency. This is a time for vigorous and positive action.”

“If a man hasn’t discovered something he will die for, he isn’t fit to live.”

“Lightning makes no sound until it strikes.” 

“We are not makers of history. We are made by history.”

“These are the times for real choices and not false ones. We are at the moment when our lives must be placed on the line if our nation is to survive its own folly. Every man of humane convictions must decide on the protest that best suits his convictions, but we must all protest.”

“All labor has dignity.”

“Instinctively we struck out for dignity first because personal degradation as an inferior human being was even more keenly felt than material privation.”

“Like an unchecked cancer, hate corrodes the personality and eats away its vital unity. Hate destroys a man's sense of values and his objectivity. It causes him to describe the beautiful as ugly and the ugly as beautiful, and to confuse the true with the false and the false with the true.”

“Let us be dissatisfied until America will no longer have high blood pressure of creeds and an anemia of deeds. Let us be dissatisfied until the tragic walls that separate the outer city of wealth and comfort from the inner city of poverty and despair shall be crushed by the battering rams of the fires of justice. Let us be dissatisfied until they who live on the outskirts of Hope are brought into the metropolis of daily security. Let us be dissatisfied until slums are cast into the junk heap of history and every family will live in a decent, sanitary home. Let us be dissatisfied until the dark yesterdays of segregated schools will be transformed into the bright tomorrows of quality integrated education.”

“If it falls your lot to be a street sweeper, sweep streets like Michelangelo painted pictures, sweep streets like Beethoven composed music, sweep streets like Leontyne Price sings before the Metropolitan Opera. Sweep streets like Shakespeare wrote poetry. Sweep streets so well that all the hosts of heaven and earth will have to pause and say: Here lived a great street sweeper who swept his job well. If you can't be a pine at the top of the hill, be a shrub in the valley. Be be the best little shrub on the side of the hill.”
