“Darkness cannot drive out darkness: only light can do that.”

“Intelligence plus character-that is the goal of true education” 

“The time has come for an all-out war against poverty. The rich nations must use their vast resources of wealth to develop the underdeveloped, school the unschooled, and feed the unfed. Ultimately a great nation is a compassionate nation. No individual or nation can be great if it does not have a concern for "the least of these".”

“A man who does not have something for which he is willing to die is not fit to live.”

“Communism forgets that life is individual. Capitalism forgets that life is social, and the kingdom of brotherhood is found neither in the thesis of communism nor the antithesis of capitalism but in a higher synthesis. It is found in a higher synthesis that combines the truths of both.” 

“Every man must decide whether he will walk in the light of creative altruism or in the darkness of destructive selfishness.”

“On some positions, Cowardice asks the question, “Is it safe?” Expediency asks the question, “Is it politic?” And Vanity comes along and asks the question, “Is it popular?” But Conscience asks the question, “Is it right?”... The ultimate measure of a man is not where he stands in moments of convenience, but where he stands in moments of challenge, moments of great crisis and controversy.”

“If I cannot do great things, I can do small things in a great way.”

“No one can understand my conflict who has not looked into the eyes of those he loves, knowing that he has no alternative but to take a dangerous stand that leaves them tormented.” 

“Only when it is dark enough can we see the stars.”

“We cannot walk alone. And as we walk, we must make the pledge that we shall always march ahead. We cannot turn back.”

“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.”

“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.”

“In a real sense all life is inter-related. All men are caught in an inescapable network of mutuality, tied in a single garment of destiny. Whatever affects one directly, affects all indirectly. I can never be what I ought to be until you are what you ought to be, and you can never be what you ought to be until I am what I ought to be... This is the inter-related structure of reality.”

“A man who won't die for something is not fit to live.”
