“Darkness cannot drive out darkness: only light can do that. Hate cannot drive out hate: only love can do that.”

“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.”

“So the question is not whether we will be extremists, but what kind of extremists we will be. Will we be extremists for hate or for love? Will we be extremists for the preservation of injustice or for the extension of justice? In that dramatic scene on Calvary's hill three men were crucified. We must never forget that all three were crucified for the same crime--the crime of extremism. Two were extremists for immorality, and thus fell below their environment. The other, Jesus Christ, was an extremist for love, truth and goodness, and thereby rose above his environment.”

“As long as the struggle was down in Alabama and Mississippi, they could look afar and think about it and say how terrible people are. When they discovered brotherhood had to be a reality in Chicago and that brotherhood extended to next door, then those latent hostilities came out.”

“Never, never be afraid to do what's right, especially if the well-being of a person or animal is at stake. Society's punishments are small compared to the wounds we inflict on our soul when we look the other way.”

“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 arch of History is long, but it bends towards justice.”

“We have, it seems, shut the poor out of our minds and driven them from the mainstream of our society. We have allowed the poor to become invisible, and we have become angry when they make their presence felt. But just as nonviolence has exposed the ugliness of racial injustice, we must now find ways to expose and heal the sickness of poverty—not just its symptoms, but its basic causes.”

“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.”

“I've looked over, and I've seen the promised land. I may not get there with you, but I want you to know tonight that we as a people will get to the promised land. So I'm happy tonight. I'm not worried about anything. I'm not fearing any man. ”

“«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»”

“I believe that unarmed truth and unconditional love will have the final word in reality. This is why right, temporarily defeated, is stronger than evil triumphant.”

“The means by which we live have outdistanced the ends for which we live. Our scientific power has outrun our spiritual power. We have guided missiles and misguided men.”

“I have a dream that one day this nation will rise up and live out the true meaning of its creed: "We hold these truths to be self-evident, that all men are created equal." 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. I have a dream that one day even the state of Mississippi, a state sweltering with the heat of injustice, sweltering with the heat of oppression, will be transformed into an oasis of freedom and justice. I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character. I have a dream today! I have a dream that one day, down in Alabama, with its vicious racists, with its governor having his lips dripping with the words of "interposition" and "nullification" -- one day right there in Alabama little black boys and black girls will be able to join hands with little white boys and white girls as sisters and brothers. I have a dream today! I have a dream that one day every valley shall be exalted, and 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.”

“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.”
