“We are called to speak for the weak, for the voiceless, for the victims of our nation, and for those it calls enemy, for no document from human hands can make these humans any less our brothers.”

“For you will never be what you ought to be until they [your fellow humans] are what they ought to be.”

“The function of education, therefore, is to teach one to think intensively and to think critically. But education which stops with efficiency may prove the greatest menace to society. The most dangerous criminal may be the man gifted with reason, but with no morals.”

“Only a "dry as dust" religion prompts a minister to extol the glories of Heaven while ignoring the social conditions that cause men an Earthly hell.” 

“Injustice anywhere is a threat to justice everywhere.”

“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?”

“Violence is not only impractical but immoral.”

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

“If we do not act, we shall surely be dragged down the long, dark, and shameful corridors of time reserved for those who possess power without compassion, might without morality, and strength without sight.”

“The hope of a secure and livable world lies with disciplined nonconformists, who are dedicated to justice, peace, and brotherhood. The trailblazers in human, academic, scientific, and religious freedom have always been nonconformists. In any cause that concerns the progress of mankind, put your faith in the nonconformist!”

“Everyone has the power for greatness, not for fame but greatness, because greatness is determined by service.”

“Nonviolence means avoiding not only external physical violence but also internal violence of spirit. You not only refuse to shoot a man, but you refuse to hate him.”

“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.”

“One of the greatest paradoxes of the Black Power movement was that it talked unceasingly about not imitating the values of white society, but in advocating violence it was imitating the worst, the most brutal, and the most uncivilized value of American life. American Negroes had not been mass murderers. They had not murdered children in Sunday school, nor had they hung white men on trees bearing strange fruit. They had not been hooded perpetrators of violence, lynching human beings at will and drowning them at whim.”

“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.”
