“The time has come for an all-out war against poverty. The rich nations must use their vast resources of wealth to develop the underdeveloped, school the unschooled, and feed the unfed. Ultimately a great nation is a compassionate nation. No individual or nation can be great if it does not have a concern for "the least of these".”

“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?”

“Our lives begin to end the day we become silent about things that matter.”

“Science investigates, religion interprets. Science gives man knowledge which is power, religion gives man wisdom which is control. Science deals mainly with facts, religion deals with values. The two are not rivals. They are complementary. Science keeps religion from sinking into the valley of crippling irrationalism and paralysing obscurantism. Religion prevents science from falling into the marsh of obsolete materialism and moral nihilism.”

“There comes a time when one must take a position that is neither safe, nor politic, nor popular, but he must take it because conscience tells him it is right.”

“I am convinced that love is the most durable power in the world. It is not an expression of impractical idealism, but of practical realism. Far from being the pious injunction of a Utopian dreamer, love is an absolute necessity for the survival of our civilization. To return hate for hate does nothing but intensify the existence of evil in the universe. Someone must have sense enough and morality enough to cut off the chain of hate and evil, and this can only be done through love.” — Martin Luther King Jr.”

“Modern psychology has a word that is probably used more than any other word in modern psychology. It is the word “maladjusted.” This word is the ringing cry to modern child psychology. Certainly, we all want to avoid the maladjusted life. In order to have real adjustment within our personalities, we all want the well‐adjusted life in order to avoid neurosis, schizophrenic personalities. But I say to you, my friends, as I move to my conclusion, there are certain things in our nation and in the world which I am proud to be maladjusted and which I hope all men of good‐will will be maladjusted until the good societies realize. I say very honestly that I never intend to become adjusted to segregation and discrimination. I never intend to become adjusted to religious bigotry. I never intend to adjust myself to economic conditions that will take necessities from the many to give luxuries to the few. I never intend to adjust myself to the madness of militarism, to self‐defeating effects of physical violence… In other words, I’m about convinced now that there is need for a new organization in our world. The International Association for the Advancement of Creative Maladjustment‐‐men and women who will be as maladjusted as the prophet Amos. Who in the midst of the injustices of his day could cry out in words that echo across the centuries, “Let justice roll down like waters and righteousness like a mighty stream.”

“We are going to win our freedom because both the sacred heritage of our nation and the eternal will of the Almighty God are embodied in our echoing demands. So however difficult it is during this period, however difficult it is to continue to live with the agony and the continued existence of racism, however difficult it is to live amidst the constant hurt, the constant insult and the constant disrespect, I can still sing we shall overcome. We shall overcome because the arc of the moral universe is long but it bends towards justice. We shall overcome because Carlisle is right. "No lie can live forever." We shall overcome because William Cullen Bryant is right. "Truth crushed to earth will rise again." We shall overcome because James Russell Lowell is 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 nation into a beautiful symphony of brotherhood. With this faith we will be able to speed up the day when all of God's children all over this nation - black men and white men, Jews and Gentiles, Protestants and Catholics 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 are Free At Last.”

“Everything that we see is a shadow cast by that which we do not see.”

“The time is always right to do what is right.”

“La oscuridad no puede conducirte fuera de la oscuridad; sólo la luz puede hacer eso. El odio no puede conducirte fuera del odio; sólo el amor puede hacer eso.”

“Our goal is to create a beloved community and  this will require a qualitative change in our souls  as well as a quantitative change in our lives.”

“Power at its best is love implementing the demands of justice. Justice at its best is love correcting everything that stands against love.”

“If it falls your lot to be a street sweeper, sweep streets like Michelangelo painted pictures, sweep streets like Beethoven composed music, sweep streets like Leontyne Price sings before the Metropolitan Opera. Sweep streets like Shakespeare wrote poetry. Sweep streets so well that all the hosts of heaven and earth will have to pause and say: Here lived a great street sweeper who swept his job well. If you can't be a pine at the top of the hill, be a shrub in the valley. Be be the best little shrub on the side of the hill.”

“Rarely do we find men who willingly engage in hard, solid thinking. There is an almost universal quest for easy answers and half-baked solutions. Nothing pains some people more than having to think.”
