“Time itself is neutral; it can be used either destructively or constructively”

“Violence never really deals with the basic evil of the situation. Violence may murder the murderer, but it doesn’t murder murder. Violence may murder the liar, but it doesn’t murder lie; it doesn’t establish truth. Violence may even murder the dishonest man, but it doesn’t murder dishonesty. Violence may go to the point of murdering the hater, but it doesn’t murder hate. It may increase hate. It is always a descending spiral leading nowhere. This is the ultimate weakness of violence: It multiplies evil and violence in the universe. It doesn’t solve any problems.”

“Capitalism is always in danger of inspiring men to be more concerned about making a living than making a life. 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 humanity.”

“Japan knows the horror of war and has suffered as no other nation under the cloud of nuclear disaster. Certainly Japan can stand strong for a world of peace.”

“In the end we will remember not the words of our enemies...but the silence of our friends.

“Those who love peace must learn to organize as effectively as those who love war.”

“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.”

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

“Again and again we must rise to the majestic heights of meeting physical force with soul force.”

“Prima o poi arriva l'ora in cui bisogna prendere una posizione che non è né sicura, né conveniente, né popolare; ma bisogna prenderla, perché è giusta.”

“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.”

“I had a dream”

“The time is always right to do the right thing” 

“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 old guard in any society resents new methods, for old guards wear the decorations and medals won by waging battle in the accepted manner.”
