“If a man is called to be a street sweeper, he should sweep streets even as a Michaelangelo painted, or Beethoven composed music or Shakespeare wrote poetry. He should sweep streets so well that all the hosts of heaven and earth will pause to say, 'Here lived a great street sweeper who did his job well.”

“All men are caught in an inescapable network of mutuality.”

“The richer we have become materially, the poorer we become morally and spiritually. We have learned to fly in the air like birds and swim in the sea like fish, but we have not learned the simple art of living together as brothers.”

“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.”

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

“The time comes when silence is betrayal. That time has come for us today...  ...some of us who have already begun to break the silence of the night have found that the calling to speak is often a vocation of agony, but we must speak.”

“Not ordinarily do men achieve this balance of opposites. The idealists are not usually realistic, and the realists are not usually idealistic. The militant are not generally known to be passive, nor the passive to be militant. Seldom are the humble self-assertive, or the self assertive humble. ...truth is found neither in the thesis nor the antithesis, but in an emergent synthesis that reconciles the two.”

“Find a voice in a whisper.”

“In the treatment of poverty nationally, one fact stands out: there are twice as many white poor as Negro poor in the United States. Therefore I will not dwell on the experiences of poverty that derive from racial discrimination, but will discuss the poverty that affects white and Negro alike.”

“Time itself is neutral; it can be used either destructively or constructively”

“If we do not act, we shall surely be dragged down the long, dark, and shameful corridors of time reserved for those who possess power without compassion, might without morality, and strength without sight.”

“One day the absurdity of the almost universal human belief in the slavery of other animals will be palpable. We shall then have discovered our souls and become worthier of sharing this planet with them.”

“I'm concerned about a better world. I'm concerned about justice; I'm concerned about brotherhood; I'm concerned about truth. And when one is concerned about that, he can never advocate violence. For through violence you may murder a murderer, but you can't murder murder. Through violence you may murder a liar, but you can't establish truth. Through violence you may murder a hater, but you can't murder hate through violence. Darkness cannot put out darkness; only light can do that.”

“The old guard in any society resents new methods, for old guards wear the decorations and medals won by waging battle in the accepted manner.”

“Prima o poi arriva l'ora in cui bisogna prendere una posizione che non è né sicura, né conveniente, né popolare; ma bisogna prenderla, perché è giusta.”
