“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.”

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

“If today's church does not recapture the sacrificial spirit of the early church, it will lose its authenticity, forfeit the loyalty of millions, and be dismissed as an irrelevant social club with no meaning for the twentieth century.”

“Geweldloos verzet kon volgens hem alleen vruchten afwerpen als de groepen waartegen het verzet werd gepleegd over enig moreel besef beschikten”

“He who passively accepts evil is as much involved in it as he who helps to perpetrate it. He who accepts evil without protesting against it is really cooperating with it.”

“The human heart is like a ship on a stormy sea driven about by winds blowing from all four corners of heaven.”

“[Nonviolence] is directed against forces of evil rather than against persons who happen to be doing the evil. It is evil that the nonviolent resister seeks to defeat, not the persons victimized by evil.”

“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.”

“The absence of brutality and unregenerate evil is not the presence of justice. To stay murder is not the same thing as to ordain brotherhood.”

“What I'm saying to you this morning is that Communism forgets that life is individual. Capitalism forgets that life is social, and the Kingdom of Brotherhood is found neither in the thesis of Communism nor the antithesis of capitalism but in a higher synthesis.”

“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 humanity.”

“We must live together as brothers or perish together as fools.”

“Through our scientific and technological genius we've made of this world a neighborhood. And now through our moral and ethical commitment we must make of it a brotherhood. We must all learn to live together as brothers—or we will all perish together as fools.”

“Racial injustice around the world. Poverty. War. When man solves these three great problems he will have squared his moral progress with his scientific progress. And, more importantly, he will have learned the practical art of living in harmony.”

"Nothing in the world is more dangerous than sincere ignorance and conscientious stupidity.”
