“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.”

“And I must say tonight that a riot is the language of the unheard. And what is it America has failed to hear? ... It has failed to hear that the promises of freedom and justice have not been met. And it has failed to hear that large segments of white society are more concerned about tranquility and the status quo than about justice and humanity.”

“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?”

“Time itself is neutral; it can be used either destructively or constructively. More and more I feel that the people of ill will have used time much more effectively than have the people of good will. We will have to repent in this generation not merely for the hateful words and actions of the bad people but for the appalling silence of the good people. Human progress never rolls in on wheels of inevitability; it comes through the tireless efforts of men willing to work to be co-workers with God, and without this hard work, time itself becomes an ally of the forces of social stagnation. We must use time creatively, in the knowledge that the time is always ripe to do right.”

“In our society, it is psychological murder to deprive a man of a job...you are in substance saying to that man "You have no right to exist.”

“We have flown the air like birds and swum the sea like fishes, but have yet to learn the simple act of walking the earth like brothers.”

“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.”

“We are prone to judge success by the index of our salaries or the size of our automobiles rather than by the quality of our service and relationship to mankind.” 

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

“Human progress is neither automatic nor inevitable... Every step toward the goal of justice requires sacrifice, suffering, and struggle; the tireless exertions and passionate concern of dedicated individuals.”

“No one really knows why they are alive until they know what they'd die for.”

“In a real sense all life is inter-related. All men are caught in an inescapable network of mutuality, tied in a single garment of destiny. Whatever affects one directly, affects all indirectly. I can never be what I ought to be until you are what you ought to be, and you can never be what you ought to be until I am what I ought to be... This is the inter-related structure of reality.”

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

“When you cut facilities, slash jobs, abuse power, discriminate, drive people into deeper poverty and shoot people dead whilst refusing to provide answers or justice, the people will rise up and express their anger and frustration if you refuse to hear their cries. A riot is the language of the unheard.”

“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.”
