“I have consistently preached that nonviolence demands that the means we use must be as pure as the ends we seek. I have tried to make clear that it is wrong to use immoral means to attain moral ends. But now I must affirm that it is just as wrong, or perhaps even more so, to use moral means to preserve immoral ends.”

“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.”

“We must come to see that peace is not merely a distant goal we seek, but it is a means by which we arrive at that goal. We must pursue peaceful ends through peaceful means.”

“Even today there still exists in the South--and in certain areas of the North--the license that our society allows to unjust officials who implement their authority in the name of justice to practice injustice against minorities. Where, in the days of slavery, social license and custom placed the unbridled power of the whip in the hands of overseers and masters, today--especially in the southern half of the nation--armies of officials are clothed in uniform, invested with authority, armed with the instruments of violence and death and conditioned to believe that they can intimidate, main or kill Negroes with the same recklessness that once motivated the slaveowner. If one doubts this conclusion, let him search the records and find how rarely in any southern state a police officer has been punished for abusing a Negro.”

“We must condemn those who are perpetuating the violence, and not the individuals who engage in the pursuit of their constitutional rights.”

“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.”

“The Christians who engaged in infamous persecutions and shameful inquisitions were not evil men but misguided men. The churchmen who felt they had an edict from God to withstand the progress of science, whether in the form of a Copernican revolution or a Darwinian theory of natural selection, were not mischievous men but misinformed men.”

“«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»”

“Let us realize the arc of the moral universe is long but it bends toward justice.”

“We live in a world of guided missiles and misguided men".”

“This would be an unbearable world were God to have only a single light, but we may be consoled that God has two lights: a light to guide us in the brightness of the day when hopes are fulfilled and circumstances are favorable, and a light to guide us in the darkness of the midnight when we are thwarted and the slumbering giants of gloom and hopelessness rise in our souls.”

“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.”

“There comes a time when silence is betrayal.”

“Injustice anywhere is a threat to justice everywhere.”

“Yes, if you want to say that I was a drum major, say that I was a drum major for justice. Say that I was a drum major for peace. I was a drum major for righteousness. And all of the other shallow things will not matter. I won't have any money to leave behind. I won't have the fine and luxurious things of life to leave behind. But I just want to leave a committed life behind. And that's all I want to say.”
