“Science investigates, religion interprets. Science gives man knowledge which is power, religion gives man wisdom which is control. Science deals mainly with facts, religion deals with values. The two are not rivals. They are complementary. Science keeps religion from sinking into the valley of crippling irrationalism and paralysing obscurantism. Religion prevents science from falling into the marsh of obsolete materialism and moral nihilism.”

“Like anybody, I would like to have a long life. Longevity has its place. But I'm not concerned about that now. I just want to do God's will.”

“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.”

“Courage faces fear and thereby masters it”

“The potential beauty of human life is constantly made ugly by man's ever-recurring song of retaliation.”

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

“The quality, not the longevity, of one's life is what is important.”

“In a world facing the revolt of ragged and hungry masses of God's children; in a world torn between the tensions of East and West, white and colored, individuals and collectivists; in a world whose cultural and spiritual power lags so far behind her technological capabilities that we live each day on the verge of nuclear co-annihilation; in this world, nonviolence is no longer an option for intellectual analysis, it is an imperative for action”

“And I must say tonight that a riot is the language of the unheard. And what is it America has failed to hear? ... It has failed to hear that the promises of freedom and justice have not been met. And it has failed to hear that large segments of white society are more concerned about tranquility and the status quo than about justice and humanity.”

“You know my friends, there comes a time when people get tired of being trampled by the iron feet of oppression. There comes a time my friends, when people get tired of being plunged across the abyss of humiliation, where they experience the bleakness of nagging despair. There comes a time when people get tired of being pushed out of the glittering sunlight of life's July and left standing amid the piercing chill of an alpine November. There comes a time.”

“I accept this award today with an abiding faith in America and an audacious faith in the future of mankind. I refuse to accept despair as the final response to the ambiguities of history. I refuse to accept the idea that the "isness" of man's present nature makes him morally incapable of reaching up for the eternal "oughtness" that forever confronts him. I refuse to accept the idea that man is mere flotsom and jetsom in the river of life, unable to influence the unfolding events which surround him. I refuse to accept the view that mankind is so tragically bound to the starless midnight of racism and war that the bright daybreak of peace and brotherhood can never become a reality.”

“But life at its best is a creative synthesis of opposites in fruitful harmony.”

“And when you come to the point that you look in the face of every man and see deep down within him what religion calls "the image of God," you begin to love him in spite of. No matter what he does, you see God’s image there. There is an element of goodness that he can never sluff off. Discover the element of good in your enemy. And as you seek to hate him, find the center of goodness and place your attention there and you will take a new attitude. Another way that you love your enemy is this: When the opportunity presents itself for you to defeat your enemy, that is the time which you must not do it. There will come a time, in many instances, when the person who hates you most, the person who has misused you most, the person who has gossiped about you most, the person who has spread false rumors about you most, there will come a time when you will have an opportunity to defeat that person. It might be in terms of a recommendation for a job; it might be in terms of helping that person to make some move in life. That’s the time you must do it. That is the meaning of love. In the final analysis, love is not this sentimental something that we talk about. It’s not merely an emotional something. Love is creative, understanding goodwill for all men. It is the refusal to defeat any individual. When you rise to the level of love, of its great beauty and power, you seek only to defeat evil systems. Individuals who happen to be caught up in that system, you love, but you seek to defeat the system.”

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

“The true measure of a man is not how he behaves in moments of comfort and convenience but how he stands at times of controversy and challenges.”
