“our slogan must not be “Burn, baby, burn.” It must be, “Build, baby, build.” “Organize, baby, organize.” Yes, our slogan must be “Learn, baby, learn,” so that we can earn, baby, earn.”

“What is more tragic than to see a person who has risen to the disciplined heights of tough-mindedness but has at the same time sunk to the passionless depths of hard-heartedness?”

“Any religion that professes to be concerned about the souls of men and is not concerned about the slums that damn them, the economic conditions that strangle them and the social conditions that cripple them is a spiritually moribund religion awaiting burial.”

“time itself is neutral; it can be used either destructively or constructively. More and more I feel that the people of ill will have used time much more effectively than have the people of good will. We will have to repent in this generation not merely for the hateful words and actions of the bad people but for the appalling silence of the good people. Human progress never rolls in on wheels of inevitability; it comes through the tireless efforts of men willing to be co-workers with God, and without this hard work, time itself becomes an ally of the forces of social stagnation. We must use time creatively, in the knowledge that the time is always ripe to do right. Now is the time to make real the promise of democracy and transform our pending national elegy into a creative psalm of brotherhood. Now is the time to lift our national policy from the quicksand of racial injustice to the solid rock of human dignity.”

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

“I have a dream 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!”

“We should never forget that everything Adolph Hitler did in Germany was "legal" and everything the Hungarian freedom fighers did in Hungary was "illegal." It was "illegal" to aid and comfort a Jew in Hitler's Germany.”

“I have decided to stick to love...Hate is too great a burden to bear.”

“We shall overcome.” 

“Todo hombre debe decidir si caminará a la luz del altruismo creativo o en la oscuridad del egoísmo destructivo. Éste es el juicio. La pregunta más urgente, e ineludible, de la vida es: ¿Qué estás haciendo por los demás?”

“There is nothing more dangerous than to build a society with a large segment of people in that society who feel that they have no stake in it; who feel that that have nothing to lose. People who have stake in their society, protect that society, but when they don't have it, they unconsciously want to destroy it.”

“I am convinced that it is one of the most unjust wars that has ever been fought in the history of the world. Our involvement in the war in Vietnam has torn up the Geneva Accord. It has strengthened the military-industrial complex; it has strengthened the forces of reaction in our nation. It has put us against the self-determination of a vast majority of the Vietnamese people, and put us in the position of protecting a corrupt regime that is stacked against the poor.”

“Love your enemies”

“And when you come to the point that you look in the face of every man and see deep down within him what religion calls "the image of God," you begin to love him in spite of. No matter what he does, you see God’s image there. There is an element of goodness that he can never sluff off. Discover the element of good in your enemy. And as you seek to hate him, find the center of goodness and place your attention there and you will take a new attitude. Another way that you love your enemy is this: When the opportunity presents itself for you to defeat your enemy, that is the time which you must not do it. There will come a time, in many instances, when the person who hates you most, the person who has misused you most, the person who has gossiped about you most, the person who has spread false rumors about you most, there will come a time when you will have an opportunity to defeat that person. It might be in terms of a recommendation for a job; it might be in terms of helping that person to make some move in life. That’s the time you must do it. That is the meaning of love. In the final analysis, love is not this sentimental something that we talk about. It’s not merely an emotional something. Love is creative, understanding goodwill for all men. It is the refusal to defeat any individual. When you rise to the level of love, of its great beauty and power, you seek only to defeat evil systems. Individuals who happen to be caught up in that system, you love, but you seek to defeat the system.”

“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.”
