Excerpted from King's Nobel Lecture, Dec. 11, 1964, upon his receiving the Nobel Peace Prize.

I would like to use this lofty and historic platform to discuss what appears to me to be the most pressing problem confronting mankind today. Modern man has brought this whole world to an awe-inspiring threshold of the future. He has reached new and astonishing peaks of scientific success. He has produced machines that think and instruments that peer into the unfathomable ranges of interstellar space. He has built gigantic bridges to span the seas and gargantuan buildings to kiss the skies. His airplanes and spaceships have dwarfed distance, placed time in chains, and carved highways through the stratosphere. This is a dazzling picture of modern man’s scientific and technological progress.

Yet, in spite of these spectacular strides in science and technology, and still unlimited ones to come, something basic is missing. There is a sort of poverty of the spirit which stands in glaring contrast to our scientific and technological abundance. The richer we have become materially, the poorer we have become morally and spiritually. We have learned to fly the air like birds and swim the sea like fish, but we have not learned the simple art of living together as brothers.

This problem of spiritual and moral lag, which constitutes modern man’s chief dilemma, expresses itself in three larger problems which grow out of man’s ethical infantilism. Each of these problems, while appearing to be separate and isolated, is inextricably bound to the other. I refer to racial injustice, poverty, and war.

Prejudice

The first problem that I would like to mention is racial injustice. The struggle to eliminate the evil of racial injustice constitutes one of the major struggles of our time.

Fortunately, some significant strides have been made in the struggle to end the long night of racial injustice. In the United States we have witnessed the gradual demise of the system of racial segregation. The Supreme Court’s decision of 1954 outlawing segregation in the public schools gave a legal and constitutional deathblow to the whole doctrine of separate but equal.

Another indication that progress is being made was found in the recent presidential election in the United States. The American people revealed great maturity by overwhelmingly rejecting a presidential candidate (Republican Barry Goldwater) who had become identified with extremism, racism, and retrogression. The voters of our nation rendered a telling blow to the radical right. They defeated those elements in our society which seek to pit white against Negro and lead the nation down a dangerous Fascist path.

Let me not leave you with a false impression. The problem is far from solved. We still have a long, long way to go before the dream of freedom is a reality for the Negro in the United States. To put it figuratively in biblical language, we have left the dusty soils of Egypt and crossed a Red Sea whose waters had for years been hardened by a long and piercing winter of massive resistance. But before we reach the majestic shores of the Promised Land, there is a frustrating and bewildering wilderness ahead. We must still face prodigious hilltops of opposition and gigantic mountains of resistance. But with patient and firm determination we will press on until every valley of despair is exalted to new peaks of hope, until every mountain of pride and irrationality is made low by the leveling process of humility and compassion; until the rough places of injustice are transformed into a smooth plane of equality, of opportunity.

Poverty

A second evil which plagues the modern world is that of poverty. Like a monstrous octopus, it projects its nagging, prehensile tentacles in lands and villages all over the world. Almost two-thirds of the peoples of the world go to bed hungry at night. So it is obvious that if man is to redeem his spiritual and moral “lag” he must go all out to bridge the social and economic gulf between the “haves” and the “have nots” of the world. Poverty is one of the most urgent items on the agenda of modern life.

The time has come for an all-out world 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.” Deeply etched in the fiber of our religious tradition is the conviction that men are made in the image of God and that they are souls of infinite metaphysical value, the heirs of a legacy of dignity and worth. If we feel this as a profound moral fact, we cannot be content to see men hungry, to see men victimized with starvation and ill health when we have the means to help them. The wealthy nations must go all out to bridge the gulf between the rich minority and the poor majority.

War

A third great evil confronting our world is that of war. We must fix our vision not merely on the negative expulsion of war, but upon the positive affirmation of peace. We must see that peace represents a sweeter music, a cosmic melody that is far superior to the discords of war. Somehow, we must transform the dynamics of the world power struggle from the negative nuclear arms race which no one can win to a positive contest to harness man’s creative genius for the purpose of making peace and prosperity a reality for all of the nations of the world. In short, we must shift the arms race into a peace race.

Let me close by saying that I have the personal faith that mankind will somehow rise up to the occasion and give new directions to an age drifting rapidly to its doom. Every crisis has both its dangers and its opportunities. It can spell either salvation or doom. In a dark confused world, the kingdom of God may yet reign in the hearts of men.
