“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.”

“Let us be dissatisfied until America will no longer have high blood pressure of creeds and an anemia of deeds. Let us be dissatisfied until the tragic walls that separate the outer city of wealth and comfort from the inner city of poverty and despair shall be crushed by the battering rams of the fires of justice. Let us be dissatisfied until they who live on the outskirts of Hope are brought into the metropolis of daily security. Let us be dissatisfied until slums are cast into the junk heap of history and every family will live in a decent, sanitary home. Let us be dissatisfied until the dark yesterdays of segregated schools will be transformed into the bright tomorrows of quality integrated education.”

“...The straitjackets of race prejudice and discrimination do not wear only southern labels. The subtle, psychological technique of the North has approached in its ugliness and victimization of the Negro the outright terror and open brutality of the South.”

“Morality cannot be legislated, but behavior can be regulated. Judicial decrees may not change the heart, but they can restrain the heartless.”

“Returning violence for violence multiplies violence, adding deeper darkness to a night already devoid of stars... Hate cannot drive out hate: only love can do that.”

“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.”

“There is no noise as powerful as the sound of the marching feet of a determined people.”

“As my sufferings mounted I soon realized that there were two ways in which I could respond to my situation -- either to react with bitterness or seek to transform the suffering into a creative force. I decided to follow the latter course.”

“First, we must develop and maintain the capacity to forgive. He who is devoid of the power to forgive is devoid of the power to love. It is impossible even to begin the act of loving one’s enemies without the prior acceptance of the necessity, over and over again, of forgiving those who inflict evil and injury upon us. It is also necessary to realize that the forgiving act must always be initiated by the person who has been wronged, the victim of some great hurt, the recipient of some tortuous injustice, the absorber of some terrible act of oppression. The wrongdoer may request forgiveness. He may come to himself, and, like the prodigal son, move up some dusty road, his heart palpitating with the desire for forgiveness. But only the injured neighbor, the loving father back home, can really pour out the warm waters of forgiveness.”

“The end of life is not to be happy, nor to achieve pleasure and avoid pain, but to do the will of God, come what may.”

“I could never again raise my voice against the violence of the oppressed, without having first spoken clearly to the greatest purveyor of violence in the world today – my own government.”

“Darkness cannot drive out darkness: only light can do that.”

“Babies, we are told, are the latest news from heaven.”

“The surest way to be happy is to seek happiness for others.”

“Please be peaceful. We believe in law and order. We are not advocating violence, I want you to love your enemies... for what we are doing is right, what we are doing is just -- and God is with us.”
