“To have serpentlike qualities devoid of dovelike qualities is to be passionless, mean, and selfish. To have dovelike without serpentlike qualities is to be sentimental, anemic, and aimless. We must combine strongly marked antitheses.”

“I have tried to offer them my deepest compassion while maintaining my conviction that social change comes most meaningfully through nonviolent action.”

“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.”

“It’s all right to tell a man to lift himself by his own bootstraps, but it is cruel jest to say to a bootless man that he ought to lift himself by his own bootstraps.”

“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.”

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

“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.”

“And when this happens, when we allow freedom ring, when we let it ring from every village and every hamlet, from every state and every city, we will be able to speed up that day when all of God's children, 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!”

“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.”

“Our scientific power has outrun our spiritual power. We have guided missiles and misguided men.”

“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.”

“The belief that God will do everything for man is as untenable as the belief that man can do everything for himself. It, too, is based on a lack of faith. We must learn that to expect God to do everything while we do nothing is not faith but superstition.”

“Si el hombre no ha descubierto nada por lo que morir, no es digno de vivir.”

“...privileged groups seldom give up their privileges voluntarily.”

“One day we will learn that the heart can never be totally right when the head is totally wrong”
