“Science investigates, religion interprets. Science gives man knowledge which is power, religion gives man wisdom which is control. Science deals mainly with facts, religion deals with values. The two are not rivals. They are complementary. Science keeps religion from sinking into the valley of crippling irrationalism and paralysing obscurantism. Religion prevents science from falling into the marsh of obsolete materialism and moral nihilism.”

“Love is the only force capable of transforming an enemy into a friend.”

“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 words 'bad timing' came to be ghosts haunting our every move in Birmingham. Yet people who used this argument were ignorant of the background of our planning...they did not realize that it was ridiculous to speak of timing when the clock of history showed that the Negro had already suffered one hundred years of delay.”

“Even where the polls are open to all, Negroes have shown themselves too slow to exercise their voting privileges. There must be a concerted effort on the part of Negro leaders to arouse their people from their apathetic indifference to this obligation of citizenship. In the past, apathy was a moral failure. Today, it is a form of moral and political suicide.”

“The potential beauty of human life is constantly made ugly by man's ever-recurring song of retaliation.”

“This is the unusual thing about nonviolence -- nobody is defeated, everybody shares in the victory.”

“If a man hasn’t found something he will die for, he isn’t fit to live.”

“Nonviolence is a powerful and just weapon. It is a weapon unique in history, which cuts without wounding and ennobles the man who wields it.”

“If we are to have peace on earth, our loyalties must become ecumenical rather than sectional. Our loyalties must transcend our race, our tribe, our class, and our nation; and this means we must develop a world perspective.”

“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.”

“Something is happening in Memphis; something is happening in our world. And you know, if I were standing at the beginning of time, with the possibility of taking a kind of general and panoramic view of the whole of human history up to now, and the Almighty said to me, "Martin Luther King, which age would you like to live in?" I would take my mental flight by Egypt and I would watch God's children in their magnificent trek from the dark dungeons of Egypt through, or rather across the Red Sea, through the wilderness on toward the promised land. And in spite of its magnificence, I wouldn't stop there. I would move on by Greece and take my mind to Mount Olympus. And I would see Plato, Aristotle, Socrates, Euripides and Aristophanes assembled around the Parthenon. And I would watch them around the Parthenon as they discussed the great and eternal issues of reality. But I wouldn't stop there. I would go on, even to the great heyday of the Roman Empire. And I would see developments around there, through various emperors and leaders. But I wouldn't stop there. I would even come up to the day of the Renaissance, and get a quick picture of all that the Renaissance did for the cultural and aesthetic life of man. But I wouldn't stop there. I would even go by the way that the man for whom I am named had his habitat. And I would watch Martin Luther as he tacked his ninety-five theses on the door at the church of Wittenberg. But I wouldn't stop there. I would come on up even to 1863, and watch a vacillating President by the name of Abraham Lincoln finally come to the conclusion that he had to sign the Emancipation Proclamation. But I wouldn't stop there. I would even come up to the early thirties, and see a man grappling with the problems of the bankruptcy of his nation. And come with an eloquent cry that we have nothing to fear but "fear itself." But I wouldn't stop there.”

“Human progress never rolls in on the wheels of inevitability; it comes through the tireless efforts of [people] willing to be co-workers with God.”

“The road to freedom is a difficult, hard road. It always makes for temporary setbacks.”
