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

“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.”

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

“I was in the kitchen drinking coffee when I heard Coretta cry, "Martin, Martin, come quickly!" I put down my cup and ran toward the living room. As I approached the front window Coretta pointed joyfully to a slowly moving bus: "Darling, it's empty!”

“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.”

“As I went through this period one night I picked up an article entitled "The Children of Vietnam," and I read it. And after reading that article, I said to myself, "Never again will I be silent on an issue that is destroying the soul of our nation and destroying thousands and thousands of little children in Vietnam." I came to the conclusion that there is an existential moment in your life when you must decide to speak for yourself; nobody else can speak for you.”

“The quality, not the longevity, of one's life is what is important.”

“God is able to give you the power to endure that which cannot be changed... Why be anxious? Come what may, God is able.”

“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.”

“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.”

“May I say just a word to those of you who are struggling against this evil. Always be sure that you struggle with Christian methods and Christian weapons. Never succumb to the temptation of becoming bitter. As you press on for justice, be sure to move with dignity and discipline, using only the weapon of love. Let no man pull you so low as to hate him”

“We know through painful experience that freedom is never voluntarily given by the oppressor; it must be demanded by the oppressed.”

“All of the people of the world cannot do the so-called big things. Some of us will have to be content doing the so-called little things, but we must do the little things in a big way. We must do the ordinary things in an extraordinary manner. And we must overcome our sense of inferiority by doing just this - by somehow accepting that we have to do and doing that well”

“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.”

“The function of education, therefore, is to teach one to think intensively and to think critically. But education which stops with efficiency may prove the greatest menace to society. The most dangerous criminal may be the man gifted with reason, but with no morals.”
