“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.”

“We have, it seems, shut the poor out of our minds and driven them from the mainstream of our society. We have allowed the poor to become invisible, and we have become angry when they make their presence felt. But just as nonviolence has exposed the ugliness of racial injustice, we must now find ways to expose and heal the sickness of poverty—not just its symptoms, but its basic causes.”

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

“What you’re saying may get you a foundation grant but it won’t get you into the kingdom of truth.”

“We are going to win our freedom because both the sacred heritage of our nation and the eternal will of the Almighty God are embodied in our echoing demands. So however difficult it is during this period, however difficult it is to continue to live with the agony and the continued existence of racism, however difficult it is to live amidst the constant hurt, the constant insult and the constant disrespect, I can still sing we shall overcome. We shall overcome because the arc of the moral universe is long but it bends towards justice. We shall overcome because Carlisle is right. "No lie can live forever." We shall overcome because William Cullen Bryant is right. "Truth crushed to earth will rise again." We shall overcome because James Russell Lowell is right. "Truth forever on the scaffold, wrong forever on the throne."   Yet that scaffold sways the future. We shall overcome because the Bible is right.  "You shall reap what you sow." With this faith we will be able to hew out of the mountain of despair, a stone of hope. With this faith we will be able to transform the jangling discords of our nation into a beautiful symphony of brotherhood. With this faith we will be able to speed up the day when all of God's children all over this nation - 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.”

“But I am also concerned about our moral uprightness and the health of our souls. Therefore I must oppose any attempt to gain our freedom by the methods of malice, hate, and violence that have characterized our oppressors. Hate is just as injurious to the hater as it is to the hated. Like an unchecked cancer, hate corrodes the personality and eats away its vital unity. Many of our inner conflicts are rooted in hate. This is why psychiatrists say, “Love or perish.” Hate is too great a burden to bear.”

“If we do not act, we shall surely be dragged down the long, dark, and shameful corridors of time reserved for those who possess power without compassion, might without morality, and strength without sight.”

“Whatever measure of influence I had as a result of the importance which the world attaches to the Nobel Peace Prize would have to be used to bring the philosophy of nonviolence to all the world’s people who grapple with the age-old problem of racial injustice.”

“One has a moral responsibility to disobey unjust laws.”

“Let no man pull you low enough to hate him.”

“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.”

“Take the first step in faith, you don't have to see the whole staircase, just take the first step.”

“I mourn the loss of thousands of precious lives, but I will not rejoice in the death of one, not even the enemy”

“We must forever conduct our struggle on the high plane of dignity and discipline. We must not allow our creative protest to degenerate into physical violence. Again and again we must rise to the majestic heights of meeting physical force with soul force.”

“When we look at modern man, we have to face the fact...that modern man suffers from a kind of poverty of the spirit, which stands in glaring contrast to his scientific and technological abundance; We've learned to fly the air like birds, we've learned to swim the seas like fish, and yet we haven't learned to walk the Earth as brothers and sisters...”
