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

“Life's most persistent and urgent question is, 'What are you doing for others?”

“For you will never be what you ought to be until they [your fellow humans] are what they ought to be.”

“Human progress is neither automatic nor inevitable... Every step toward the goal of justice requires sacrifice, suffering, and struggle; the tireless exertions and passionate concern of dedicated individuals.”

“We must rapidly begin the shift from a "thing-oriented" society to a "person-oriented" society. When machines and computers, profit motives and property rights are considered more important than people, the giant triplets of racism, materialism, and militarism are incapable of being conquered.”

“Through our scientific genius, we have made of this world a neighborhood; now through our moral and spiritual development, we must make of it a brotherhood. In a real sense, we must all learn to live together as brothers or we will all perish together as fools. We must come to see that no individual can live alone. We must all live together; we must all be concerned about each other.”

“I have a dream that one day on the red hills of Georgia, the sons of former slaves and the sons of former slave owners will be able to sit down together at the table of brotherhood.”

“Too unconcerned to love and too passionless to hate, too detached to be selfish and too lifeless to be unselfish, too indifferent to experience joy and too cold to express sorrow, they are neither dead nor alive; they merely exist.”

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

“We all too often have socialism for the rich and rugged free market capitalism for the poor.”

"Nothing in the world is more dangerous than sincere ignorance and conscientious stupidity.”

“This would be an unbearable world were God to have only a single light, but we may be consoled that God has two lights: a light to guide us in the brightness of the day when hopes are fulfilled and circumstances are favorable, and a light to guide us in the darkness of the midnight when we are thwarted and the slumbering giants of gloom and hopelessness rise in our souls.”

“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.”

“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. It is found in a higher synthesis that combines the truths of both.” 

“There is at the outset a very obvious and almost facile connection between the war in Vietnam and the struggle I, and others, have been waging in America. A few years ago there was a shining moment in that struggle. It seemed as if there was a real promise of hope for the poor -- both black and white -- through the poverty program. There were experiments, hopes, new beginnings. Then came the buildup in Vietnam and I watched the program broken and eviscerated as if it were some idle political plaything of a society gone mad on war, and I knew that America would never invest the necessary funds or energies in rehabilitation of its poor so long as adventures like Vietnam continued to draw men and skills and money like some demonic destructive suction tube.”
