“We shall overcome.” 

“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!”

“Even where the polls are open to all, Negroes have shown themselves too slow to exercise their voting privileges. There must be a concerted effort on the part of Negro leaders to arouse their people from their apathetic indifference to this obligation of citizenship. In the past, apathy was a moral failure. Today, it is a form of moral and political suicide.”

“Let Freedom Ring.”

“I am convinced that love is the most durable power in the world. It is not an expression of impractical idealism, but of practical realism. Far from being the pious injunction of a Utopian dreamer, love is an absolute necessity for the survival of our civilization. To return hate for hate does nothing but intensify the existence of evil in the universe. Someone must have sense enough and morality enough to cut off the chain of hate and evil, and this can only be done through love.” — Martin Luther King Jr.”

“I'm concerned about a better world. I'm concerned about justice; I'm concerned about brotherhood; I'm concerned about truth. And when one is concerned about that, he can never advocate violence. For through violence you may murder a murderer, but you can't murder murder. Through violence you may murder a liar, but you can't establish truth. Through violence you may murder a hater, but you can't murder hate through violence. Darkness cannot put out darkness; only light can do that.”

“My friends, we cannot win the respect of the white people of the South or elsewhere if we are willing to trade the future of our children for our personal safety or comfort. Moreover, we must learn that passively to accept an unjust system is to cooperate with that system, and thereby to become a participant in its evil. ... 'Put up thy sword.”

“Returning violence for violence multiplies violence, adding deeper darkness to a night already devoid of stars... Hate cannot drive out hate: only love can do that.”

“Even today there still exists in the South--and in certain areas of the North--the license that our society allows to unjust officials who implement their authority in the name of justice to practice injustice against minorities. Where, in the days of slavery, social license and custom placed the unbridled power of the whip in the hands of overseers and masters, today--especially in the southern half of the nation--armies of officials are clothed in uniform, invested with authority, armed with the instruments of violence and death and conditioned to believe that they can intimidate, main or kill Negroes with the same recklessness that once motivated the slaveowner. If one doubts this conclusion, let him search the records and find how rarely in any southern state a police officer has been punished for abusing a Negro.”

“We are faced with the fact, my friends, that tomorrow is today. Procrastination is still the thief of time. Over the bleached bones and jumbled residues of numerous civilizations are written the pathetic words ‘Too Late’.”

“I have a dream that one day the state of Alabama, whose governor’s lips are presently dripping with the words of interposition and nullification, will be transformed into a situation where little black boys and black girls will be able to join hands with little white boys and white girls and walk together as sisters and brothers. I have a dream today. I have a dream that one day every valley shall be exalted, every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight, and the glory of the Lord shall be revealed, and all flesh shall see it together. This is our hope. This is the faith with which I return to the South. With this faith we will be able to hew out of the mountain of despair a stone of hope. With this faith we will be able to transform the jangling discords of our nation into a beautiful symphony of brotherhood. With this faith we will be able to work together, to pray together, to struggle together, to go to jail together, to stand up for freedom together, knowing that we will be free one day.”

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

“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.”

“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.”

“it is just as wrong, or even perhaps more so, to use moral means to preserve immoral ends.”
