“Todo hombre debe decidir si caminará a la luz del altruismo creativo o en la oscuridad del egoísmo destructivo. Éste es el juicio. La pregunta más urgente, e ineludible, de la vida es: ¿Qué estás haciendo por los demás?”

“I always contended that we as a race must not seek to rise from a position of disadvantage to one of advantage, but to create a moral balance in society where democracy and brotherhood would be reality for all men.”

“Let no man pull you so low as to hate him.”

“One day the absurdity of the almost universal human belief in the slavery of other animals will be palpable. We shall then have discovered our souls and become worthier of sharing this planet with them.”

“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.”

“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.”

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

“I became convinced that noncooperation with evil is as much a moral obligation as is cooperation with good.”

“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.”

“Economic insecurity strangles the physical and cultural growth of its victims. Not only are millions deprived of formal education and proper health facilities but our most fundamental social unit—the family—is tortured, corrupted, and weakened by economic insufficiency. When a Negro man is inadequately paid, his wife must work to provide the simple necessities for the children. When a mother has to work she does violence to motherhood by depriving her children of her loving guidance and protection; often they are poorly cared for by others or by none—left to roam the streets unsupervised. It is not the Negro alone who is wronged by a disrupted society; many white families are in similar straits. The Negro mother leaves home to care for—and be a substitute mother for—white children, while the white mother works. In this strange irony lies the promise of future correction.”

“Right, temporarily defeated, is stronger than evil triumphant.”

“I've looked over, and I've seen the promised land. I may not get there with you, but I want you to know tonight that we as a people will get to the promised land. So I'm happy tonight. I'm not worried about anything. I'm not fearing any man. ”

“Some of us who have already begun to break the silence of the night have found that the calling to speak is often a vocation of agony, but we must speak. We must speak with all the humility that is appropriate to our limited vision, but we must speak.”

“If we do an eye for an eye and a tooth for a tooth, we will be a blind and toothless nation.”

“The means by which we live have outdistanced the ends for which we live. Our scientific power has outrun our spiritual power. We have guided missiles and misguided men.”
