“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?”

“We are now faced with the fact that tomorrow is today. We are confronted with the fierce urgency of now. In this unfolding conundrum of life and history, there "is" such a thing as being too late. This is no time for apathy or complacency. This is a time for vigorous and positive action.”

“I became convinced that noncooperation with evil is as much a moral obligation as is cooperation with good.”

“Lightning makes no sound until it strikes.” 

“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.”

“Human beings with all their faults and strengths constitute the mechanism of a social movement. They must make mistakes and learn from them, make more mistakes and learn anew. They must taste defeat as well as success, and discover how to live with each. Time and action are the teachers.”

“An individual has not started living until he can rise above the narrow confines of his individualistic concerns to the broader concerns of all humanity.”

“Whites, it must frankly be said, are not putting in a similar mass effort to reeducate themselves out of their racial ignorance. It is an aspect of their sense of superiority that the white people of America believe they have so little to learn.”

“A true revolution of values will soon cause us to question the fairness and justice of many of our past and present policies. On the one hand we are called to play the good Samaritan on life’s roadside; but that will be only an initial act. One day we must come to see that the whole Jericho road must be transformed so that men and women will not be constantly beaten and robbed as they make their journey on life’s highway. True compassion is more than flinging a coin to a beggar; it is not haphazard and superficial. It comes to see that an edifice which produces beggars needs restructuring. A true revolution of values will soon look uneasily on the glaring contrast of poverty and wealth. With righteous indignation, it will look across the seas 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 veins of people 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.”

“It may well be that we will have to repent in this generation. Not merely for the vitriolic words and the violent actions of the bad people, but for the appalling silence and indifference of the good people who sit around and say, "Wait on time.”

“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.”

“Change does not roll in on the wheels of inevitability, but comes through continuous struggle. And so we must straighten our backs and work for our freedom. A man can’t ride you unless your back is bent.”

“In a world facing the revolt of ragged and hungry masses of God's children; in a world torn between the tensions of East and West, white and colored, individuals and collectivists; in a world whose cultural and spiritual power lags so far behind her technological capabilities that we live each day on the verge of nuclear co-annihilation; in this world, nonviolence is no longer an option for intellectual analysis, it is an imperative for action”

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

“All labor has dignity.”
