“But I am also concerned about our moral uprightness and the health of our souls. Therefore I must oppose any attempt to gain our freedom by the methods of malice, hate, and violence that have characterized our oppressors. Hate is just as injurious to the hater as it is to the hated. Like an unchecked cancer, hate corrodes the personality and eats away its vital unity. Many of our inner conflicts are rooted in hate. This is why psychiatrists say, “Love or perish.” Hate is too great a burden to bear.”

“All progress is precarious, and the solution of one problem brings us face to face with another problem.”

“Injustice anywhere is injustice everywhere. Anyone who lives inside the US can never be considered an outsider anywhere in the country”

“Through our scientific and technological genius we've made of this world a neighborhood. And now through our moral and ethical commitment we must make of it a brotherhood. We must all learn to live together as brothers—or we will all perish together as fools.”

“Let us realize the arc of the moral universe is long but it bends toward justice.”

“Si supiera que el mundo se acaba mañana, yo, hoy todavía, plantaría un árbol.”

“We must use time creatively.”

“We know through painful experience that freedom is never voluntarily given by the oppressor; it must be demanded by the oppressed.”

“A man dies when he refuses to stand up for that which is right.”

“Put yourself in a state of mind where you say to yourself, 'Here is an opportunity for me to celebrate like never before, my own power, my own ability to get myself to do whatever is necessary.”

“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 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.”

“unearned suffering is redemptive.”

“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.”

“The time had come- indeed it was past due- when I had to disavow and dissociate myself from those who in the name of peace burn, maim, and kill.”
