“It may well be that we will have to repent in this generation. Not merely for the vitriolic words and the violent actions of the bad people, but for the appalling silence and indifference of the good people who sit around and say, "Wait on time.”

“We must speak with all the humility that is appropriate to our limited vision, but we must speak.”

“Through our scientific and technological genius we've made of this world a neighborhood. And now through our moral and ethical commitment we must make of it a brotherhood. We must all learn to live together as brothers—or we will all perish together as fools.”

“If a man is called to be a street sweeper. He should sweep streets even as a Michelangelo painted , or Beethoven composed music or Shakespeare wrote poetry. He should sweep streets so well that all hosts of heaven and earth pause to say; Here lives a great sweeper who did his job well "

“The early Christians rejoiced when they were deemed worthy to suffer for what they believed. In those days the Church was not merely a thermometer that recorded the ideas and principles o popular opinion; it was a thermostat that transformed the mores of society.”

“But I am also concerned about our moral uprightness and the health of our souls. Therefore I must oppose any attempt to gain our freedom by the methods of malice, hate, and violence that have characterized our oppressors. Hate is just as injurious to the hater as it is to the hated. Like an unchecked cancer, hate corrodes the personality and eats away its vital unity. Many of our inner conflicts are rooted in hate. This is why psychiatrists say, “Love or perish.” Hate is too great a burden to bear.”

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

“Only in the darkness can you see the stars.”

“I have consistently preached that nonviolence demands that the means we use must be as pure as the ends we seek.”

“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.”

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

“The richer we have become materially, the poorer we become morally and spiritually. We have learned to fly in the air like birds and swim in the sea like fish, but we have not learned the simple art of living together as brothers.”

“Three hundred years of humiliation, abuse and deprivation cannot be expected to find voice in a whisper.”
