“Don't do anything panicky. Don't get your weapons. He who lives by the sword shall perish by the sword. . . We must love our white brothers, no matter what they do to us. We must make them know that we love them. Jesus still cries out in words that echo across the centuries: 'Love your enemies; bless them that curse you; pray for them that despitefully use you.' . . . We must meet hate with love. If I am stopped, our work will not stop. For what we are doing is right. What we are doing is just. And God is with us.”

“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.”

“Bitterness has not the capacity to make the distinction between some and all. When some members of the dominant group, particularly those in power, are racist in attitude and practice, bitterness accuses the whole group.”

“The ultimate tragedy is not the oppression and cruelty by the bad people but the silence over that by the good people.”

“Again and again we must rise to the majestic heights of meeting physical force with soul force.”

“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.”

“The arc of the moral universe is long, but it bends towards justice.”

“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.”

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

“Ik raakte ervan overtuigd dat niet meewerken aan een slechte zaak net zo goed een morele verplichting inhoudt als meewerken aan iets goeds.”

“There is no gain without struggle.”

“Even if they try to kill you, you develop the inner conviction that there are some things so precious, some things so eternally true that they are worth dying for. And if a person has not found something to die for, that person isn't fit to live!”

“We should never forget that everything Adolph Hitler did in Germany was "legal" and everything the Hungarian freedom fighers did in Hungary was "illegal." It was "illegal" to aid and comfort a Jew in Hitler's Germany.”

“Any religion that professes to be concerned with the souls of men and is not concerned with the slums that damn them, the economic conditions that strangle them and the social conditions that cripple them is a dry-as-dust religion.”

“We know through painful experience that freedom is never voluntarily given by the oppressor; it must be demanded by the oppressed.”
