“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.”

“You can't stop a bird from landing on your head. But you can keep it from building a nest.”

“The surest way to be happy is to seek happiness for others.”

“And when this happens, when we allow freedom ring, when we let it ring from every village and every hamlet, from every state and every city, we will be able to speed up that day when all of God's children, black men and white men, Jews and Gentiles, Protestants and Catholics, will be able to join hands and sing in the words of the old Negro spiritual: Free at last! Free at last! Thank God Almighty, we are free at last!”

“Philanthropy is commendable, but it must not cause the philanthropist to overlook the circumstances of economic injustice which make philanthropy necessary.”

“Not everybody can be famous but everybody can be great because greatness is determined by service... You only need a heart full of grace and a soul generated by love.”

“I said to my children, 'I'm going to work and do everything that I can do to see that you get a good education. I don't ever want you to forget that there are millions of God's children who will not and cannot get a good education, and I don't want you feeling that you are better than they are. For you will never be what you ought to be until they are what they ought to be.”

“The time is always right to do what is right.”

“If you lose hope, somehow you lose the vitality that keeps moving, you lose that courage to be, that quality that helps you go on in spite of it all. And so today I still have a dream.”

“I suggested then that the prize was not given merely as recognition of past achievement, but also as recognition, a more profound recognition, that the nonviolent way, the American Negro's way, was the answer to the crucial political and moral question of our time: the need for man to overcome oppression and violence without resorting to violence and oppression.”

“A true revolution of values will soon cause us to question the fairness and justice of many of our past and present policies. On the one hand we are called to play the good Samaritan on life’s roadside; but that will be only an initial act. One day we must come to see that the whole Jericho road must be transformed so that men and women will not be constantly beaten and robbed as they make their journey on life’s highway. True compassion is more than flinging a coin to a beggar; it is not haphazard and superficial. It comes to see that an edifice which produces beggars needs restructuring. A true revolution of values will soon look uneasily on the glaring contrast of poverty and wealth. With righteous indignation, it will look across the seas and see individual capitalists of the West investing huge sums of money in Asia, Africa and South America, only to take the profits out with no concern for the social betterment of the countries, and say: “This is not just.” It will look at our alliance with the landed gentry of Latin America and say: “This is not just.” The Western arrogance of feeling that it has everything to teach others and nothing to learn from them is not just. A true revolution of values will lay hands on the world order and say of war: “This way of settling differences is not just.” This business of burning human beings with napalm, of filling our nation’s homes with orphans and widows, of injecting poisonous drugs of hate into veins of people normally humane, of sending men home from dark and bloody battlefields physically handicapped and psychologically deranged, cannot be reconciled with wisdom, justice and love. A nation that continues year after year to spend more money on military defense than on programs of social uplift is approaching spiritual death.”

“Only God is able. It is faith in Him that we must rediscover. With this faith we can transform bleak and desolate valleys into sunlit paths of joy and bring new light into the dark caverns of pessimism.”

“People fail to get along because they fear each other; they fear each other because they don't know each other; they don't know each other because they have not communicated with each other.”

“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.”

“If a man hasn’t found something he will die for, he isn’t fit to live.”
