“When our days become dreary with low-hovering clouds of despair, and when our nights become darker than a thousand midnights, let us remember that there is a creative force in this universe, working to pull down the gigantic mountains of evil, a power that is able to make a way out of no way and transform dark yesterdays into bright tomorrows. Let us realize the arc of the moral universe is long but it bends toward justice.”

1960s, How Long, Not Long (1965)

1960s, Cobo Center speech (1963)
Context: I go back to the South not with a feeling that we are caught in a dark dungeon that will never lead to a way out. I go back believing that the new day is coming. And so this afternoon, I have a dream. It is a dream deeply rooted in the American dream.
I have a dream that one day, right down in Georgia and Mississippi and Alabama, the sons of former slaves and the sons of former slave owners will be able to live together as brothers.
I have a dream this afternoon, I have a dream that one day, one day little white children and little Negro children will be able to join hands as brothers and sisters.
I have a dream this afternoon that one day, that one day men will no longer burn down houses and the church of God simply because people want to be free.
I have a dream this afternoon, I have a dream, that there will be a day that we will no longer face the atrocities that Emmett Till had to face or Medgar Evers had to face, that all men can live with dignity.
I have a dream this afternoon that my four little children, that my four little children will not come up in the same young days that I came up within, but they will be judged on the basis of the content of their character, not the color of their skin.
I have a dream this afternoon that one day right here in Detroit, Negroes will be able to buy a house or rent a house anywhere that their money will carry them and they will be able to get a job.
Yes, I have a dream this afternoon that one day in this land the words of Amos will become real and "justice will roll down like waters, and righteousness like a mighty stream."
I have a dream this evening that one day we will recognize the words of Jefferson that "all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness." I have a dream this afternoon.
I have a dream that one day every valley shall be exalted, and "every valley shall be exalted, and every hill shall be made low; the crooked places shall be made straight, and the rough places plain; and the glory of the Lord shall be revealed, and all flesh shall see it together."
I have a dream this afternoon that the brotherhood of man will become a reality in this day.
And with this faith I will go out and carve a tunnel of hope through the mountain of despair. With this faith, I will go out with you and transform dark yesterdays into bright tomorrows. With this faith, we will be able to achieve this new day when all of God's children, black men and white men, Jews and Gentiles, Protestants and Catholics, will be able to join hands and sing with the Negroes in the spiritual of old: "Free at last! Free at last! Thank God almighty, we are free at last!"

1960s, Why I Am Opposed to the War in Vietnam (1967)
Context: I have not lost faith. I'm not in despair, because I know that there is a moral order. I haven't lost faith, because the arc of the moral universe is long, but it bends toward justice. I can still sing "We Shall Overcome" because Carlyle was right: "No lie can live forever." We shall overcome because William Cullen Bryant was right: "Truth pressed to earth will rise again." We shall overcome because James Russell Lowell was right: "Truth forever on the scaffold, wrong forever on the throne." Yet, that scaffold sways the future. We shall overcome because the bible is right: "You shall reap what you sow." 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 world into a beautiful symphony of brotherhood. With this faith we will be able to speed up the day when justice will roll down like waters, and righteousness like a mighty stream. With this faith we will be able to speed up the day when the lion and the lamb will lie down together, and every man will sit under his own vine and fig tree, and none shall be afraid because the words of the Lord have spoken it. With this faith we will be able to speed up the day when all over the world we will be able to join hands and sing in the words of the old Negro spiritual, "Free at last! Free at last! Thank God Almighty, we're free at last!" With this faith, we'll sing it as we're getting ready to sing it now. Men will beat their swords into plowshares and their spears into pruning hooks. And nations will not rise up against nations, neither shall they study war anymore. And I don't know about you, I ain't gonna study war no more.

1960s, Discerning the Signs of History (1964)
Context: I'm tellin' yuh this morning, money can't save yuh. A beautiful home can't save yuh. Beautiful automobiles can't save yuh. It's God that will save us in the final analysis. And I say to this morning that history is teaching us a lesson. And I hope that we will see it. That there must be underneath all of our wills, underneath all of our material attainment, a moral and religious undergirding that will help us to know that God is our father. That he made us and that we are dependent on Him, and Him only, and when we see that, we have something. For we can arise from the fatigue of despair to the bouyancy of hope.
Dark yesterday can be transformed into bright tomorrow. When you know God, you can stand up amid the agonies and burdens of life and not despair. When you know God, you can stand up amid tension and tribulation and yet smile in the process. When you know God, you go on livin' anyhow. Nothin's gonna stop you 'cause you know that God is watching in your heart. When you know God, you have on some shoes that can help you walk through any muddy place. When you know God, you know that He is over everything. That [he]'s a rock in a weary land, that he is a shelter in the time of a storm. … When you know God, you can live and never die. We're gonna open the doors of the church, now, somebody here needs to accept the Christ. Somebody needs to come this morning. Discerning the signs of history. And as we sing who this morning will make that step. Remain true to the faith of our fathers. Somebody needs to decide Now. Who will come. When we sing will you make that step.

Ki Sayings (2003)

Games for Actors and non-Actors (1992)
Context: In truth the Theatre of the Oppressed has no end, because everything which happens in it must extend into life…. The Theatre of the Oppressed is located precisely on the frontier between fiction and reality – and this border must be crossed. If the show starts in fiction, its objective is to become integrated into reality, into life. Now in 1992, when so many certainties have become so many doubts, when so many dreams have withered on exposure to sunlight, and so many hopes have become as many deceptions – now that we are living through times and situations of great perplexity, full of doubts and uncertainties, now more than ever I believe it is time for a theatre which, at its best, will ask the right questions at the right times. Let us be democratic and ask our audiences to tell us their desires, and let us show them alternatives. Let us hope that one day – please, not too far in the future – we’ll be able to convince or force our governments, our leaders, to do the same; to ask their audiences – us – what they should do, so as to make this world a place to live and be happy in – yes, it is possible – rather than just a vast market in which we sell our goods and our souls. Let’s hope. Let’s work for it!
