“There comes a time when the cup of endurance runs over, and men are no longer willing to be plunged into the abyss of despair.”

“I do not pretend to understand the moral universe; the arc is a long one, my eye reaches but little ways; I cannot calculate the curve and complete the figure by the experience of sight, I can divine it by conscience. And from what I see I am sure it bends towards justice.”

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

“You don't have to see the whole staircase, just take the first step.”

“Let justice roll down like waters and righteousness like a mighty stream.”

“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. ”

“Whatever affects one directly, affects all indirectly. I can never be what I ought to be until you are what you ought to be. This is the interrelated structure of reality.”

“Nonviolence is a powerful and just weapon. It is a weapon unique in history, which cuts without wounding and ennobles the man who wields it.”

“All this is simply to say that all life is interrelated. We are caught in an inescapable network of mutuality; tied in a single garment of destiny. Whatever affects one directly, affects all indirectly. As long as there is poverty in this world, no man can be totally rich even if he has a billion dollars. As long as diseases are rampant and millions of people cannot expect to live more than twenty or thirty years, no man can be totally healthy, even if he just got a clean bill of health from the finest clinic in America. Strangely enough, I can never be what I ought to be until you are what you ought to be. You can never be what you ought to be until I am what I ought to be.”

“And I must say tonight that a riot is the language of the unheard. And what is it America has failed to hear? ... It has failed to hear that the promises of freedom and justice have not been met. And it has failed to hear that large segments of white society are more concerned about tranquility and the status quo than about justice and humanity.”

“A true revolution of values will soon look uneasily on the glaring contrast of poverty and wealth. With righteous indignation, it will look at thousands of working people displaced from their jobs with reduced incomes as a result of automation while the profits of the employers remain intact, and say: “This is not just.” It will look across the oceans and see individual capitalists of the West investing huge sums of money in Asia, Africa and South America, only to take the profits out with no concern for the social betterment of the countries, and say: “This is not just.” It will look at our alliance with the landed gentry of Latin America and say: “This is not just.” The Western arrogance of feeling that it has everything to teach others and nothing to learn from them is not just. A true revolution of values will lay hands on the world order and say of war: “This way of settling differences is not just.” This business of burning human beings with napalm, of filling our nation’s homes with orphans and widows, of injecting poisonous drugs of hate into the veins of peoples normally humane, of sending men home from dark and bloody battlefields physically handicapped and psychologically deranged cannot be reconciled with wisdom, justice and love. A nation that continues year after year to spend more money on military defense than on programs of social uplift is approaching spiritual death. America, the richest and most powerful nation in the world, can well lead the way in this revolution of values. There is nothing to prevent us from paying adequate wages to schoolteachers, social workers and other servants of the public to insure that we have the best available personnel in these positions which are charged with the responsibility of guiding our future generations. There is nothing but a lack of social vision to prevent us from paying an adequate wage to every American citizen whether he be a hospital worker, laundry worker, maid or day laborer. There is nothing except shortsightedness to prevent us from guaranteeing an annual minimum—and livable—income for every American family. There is nothing, except a tragic death wish, to prevent us from reordering our priorities, so that the pursuit of peace will take precedence over the pursuit of war. There is nothing to keep us from remolding a recalcitrant status quo with bruised hands until we have fashioned it into a brotherhood.”

“We are prone to judge success by the index of our salaries or the size of our automobiles rather than by the quality of our service and relationship to mankind.” 

“In the end, we will remember not the words of our enemies, but the silence of our friends.”

“We have fought hard and long for integration, as I believe we should have, and I know that we will win. But I've come to believe we're integrating into a burning house. I'm afraid that America may be losing what moral vision she may have had …. And I'm afraid that even as we integrate, we are walking into a place that does not understand that this nation needs to be deeply concerned with the plight of the poor and disenfranchised. Until we commit ourselves to ensuring that the underclass is given justice and opportunity, we will continue to perpetuate the anger and violence that tears at the soul of this nation.”

“An individual who breaks a law that conscience tells him is unjust, and who willingly accepts the penalty of imprisonment in order to arouse the conscience of the community over its injustice, is in reality expressing the highest respect for the law”
