“The ultimate weakness of violence is that it is a descending spiral, begetting the very thing it seeks to destroy. Instead of diminishing evil, it multiplies it. Through violence you may murder the liar, but you cannot murder the lie, nor establish the truth. Through violence you murder the hater, but you do not murder hate. In fact, violence merely increases hate. Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that.”

“One who breaks an unjust law must do so openly, lovingly, and with a willingness to accept the penalty.”

“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.”

“If it falls to your lot to be a street sweeper, sweep streets like Michelangelo painted pictures, sweep streets like Beethoven composed music ... Sweep streets like Shakespeare wrote poetry. Sweep streets so well that all the host of heaven and earth will have to pause and say: Here lived a great street sweeper who swept his job well.”

“The arc of the moral universe is long, but it bends towards justice.”

“One of the greatest paradoxes of the Black Power movement was that it talked unceasingly about not imitating the values of white society, but in advocating violence it was imitating the worst, the most brutal, and the most uncivilized value of American life. American Negroes had not been mass murderers. They had not murdered children in Sunday school, nor had they hung white men on trees bearing strange fruit. They had not been hooded perpetrators of violence, lynching human beings at will and drowning them at whim.”

“A man can't ride your back unless it's bent”

“But I know, somehow, that only when it is dark enough, can you see the stars.”

“First, we must develop and maintain the capacity to forgive. He who is devoid of the power to forgive is devoid of the power to love. It is impossible even to begin the act of loving one’s enemies without the prior acceptance of the necessity, over and over again, of forgiving those who inflict evil and injury upon us. It is also necessary to realize that the forgiving act must always be initiated by the person who has been wronged, the victim of some great hurt, the recipient of some tortuous injustice, the absorber of some terrible act of oppression. The wrongdoer may request forgiveness. He may come to himself, and, like the prodigal son, move up some dusty road, his heart palpitating with the desire for forgiveness. But only the injured neighbor, the loving father back home, can really pour out the warm waters of forgiveness.”

“You can't stop a bird from landing on your head. But you can keep it from building a nest.”

“I refuse to accept the view that mankind is so tragically bound to the starless midnight of racism and war that the bright daybreak of peace and brotherhood can never become a reality... I believe that unarmed truth and unconditional love will have the final word.”

“A social movement that only moves people is merely a revolt. A movement that changes both people and institutions is a revolution.”

“There is some good in the worst of us and some evil in the best of us. When we discover this, we are less prone to hate our enemies.”

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

“We must develop and maintain the capacity to forgive. He who is devoid of the power to forgive is devoid of the power to love. There is some good in the worst of us and some evil in the best of us. When we discover this, we are less prone to hate our enemies.”
