“It really boils down to this: that all life is interrelated. We are all caught in an inescapable network of mutuality, tied into a single garment of destiny. Whatever affects one directly, affects all indirectly.”

“The more I thought about human nature, the more I saw how our tragic inclination for sin/mistakes causes us to use our minds to rationalize our action.”

“If it falls your lot to be a street sweeper, sweep streets like Michelangelo painted pictures, sweep streets like Beethoven composed music, sweep streets like Leontyne Price sings before the Metropolitan Opera. Sweep streets like Shakespeare wrote poetry. Sweep streets so well that all the hosts of heaven and earth will have to pause and say: Here lived a great street sweeper who swept his job well. If you can't be a pine at the top of the hill, be a shrub in the valley. Be be the best little shrub on the side of the hill.”

“This is no time to engage in the luxury of cooling off or to take the tranquilizing drug of gradualism.”

“Injustice anywhere is a threat to justice everywhere.”

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

“Take the first step in faith, you don't have to see the whole staircase, just take the first step.”

“Freedom is never voluntarily given by the oppressor; it must be taken by the oppressed.”

“Our lives begin to end the day we become silent about things that matter.

“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 can be no deep disappointment where there is not deep love.”

“Not ordinarily do men achieve this balance of opposites. The idealists are not usually realistic, and the realists are not usually idealistic. The militant are not generally known to be passive, nor the passive to be militant. Seldom are the humble self-assertive, or the self assertive humble. ...truth is found neither in the thesis nor the antithesis, but in an emergent synthesis that reconciles the two.”

“Not only will we have to repent for the sins of bad people; but we also will have to repent for the appalling silence of good people.”
