“Never, never be afraid to do what's right, especially if the well-being of a person or animal is at stake. Society's punishments are small compared to the wounds we inflict on our soul when we look the other way.”

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

“It is simply my way of saying that I would rather be a man of conviction than a man of conformity. Occasionally in life one develops a conviction so precious and meaningful that he will stand on it till the end. That is what I have found in nonviolence.”

“Whatever I was, I owed to my family and to all those who struggled with me. But my biggest debt I owed to my wife. She was the one who gave my life meaning. All I could pledge to her, and to all those millions, was that I would do all I could to justify the faith that she, and they, had in me. I would try more than ever to make my life one of which she, and they, could be proud. I would do in private that which I knew my public responsibility demanded.”

“no labor is really menial unless you’re not getting adequate wages.”

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

“I have a dream that one day this nation will rise up and live out the true meaning of its creed: "We hold these truths to be self-evident, that all men are created equal." I have a dream that one day on the red hills of Georgia, the sons of former slaves and the sons of former slave owners will be able to sit down together at the table of brotherhood. I have a dream that one day even the state of Mississippi, a state sweltering with the heat of injustice, sweltering with the heat of oppression, will be transformed into an oasis of freedom and justice. I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character. I have a dream today! I have a dream that one day, down in Alabama, with its vicious racists, with its governor having his lips dripping with the words of "interposition" and "nullification" -- one day right there in Alabama little black boys and black girls will be able to join hands with little white boys and white girls as sisters and brothers. I have a dream today! I have a dream that one day every valley shall be exalted, and every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight; "and the glory of the Lord shall be revealed and all flesh shall see it together.”

“I've seen too much hate to want to hate, myself.”

“Let justice roll down like waters and righteousness like a mighty stream.”

“Si supiera que el mundo se acaba mañana, yo, hoy todavía, plantaría un árbol.”

“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.”

“After the opposition had failed to negotiate us into a compromise, it turned to subtler means for blocking the protest; namely, to conquer by dividing. False rumors were spread concerning the leaders of the movement. Negro workers were told by their white employers that their leaders were only concerned with making money out of the movement. Others were told that the Negro leaders rode big cars while they walked. During this period the rumor was spread that I had purchased a brand new Cadillac for myself and a Buick station wagon for my wife. Of course none of this was true.”

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

“Unity has never meant uniformity.”

“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.”
