A half a century from this August, the Rev. Martin Luther King Jr. delivered his most famous speech from the steps of the Lincoln Memorial during the civil rights march in Washington.
If you want to understand why America today honors King with a national holiday, if you want to teach your children and grandchildren why his legacy is so revered, if you want to remember how much he mattered, there are few better ways than to listen to the words he spoke.
Today, we happily turn over our space to an excerpt from that powerful address.
" ... As we walk, we must make the pledge that we shall march ahead. We cannot turn back.
"There are those who are asking the devotees of civil rights, "When will you be satisfied?" We can never be satisfied as long as our bodies, heavy with the fatigue of travel, cannot gain lodging in the motels of the highways and the hotels of the cities. We cannot be satisfied as long as the Negro's basic mobility is from a smaller ghetto to a larger one. We can never be satisfied as long as a Negro in Mississippi cannot vote and a Negro in New York believes he has nothing for which to vote. No, no, we are not satisfied, and we will not be satisfied until justice rolls down like waters and righteousness like a mighty stream ...
" ... I say to you today, my friends, that in spite of the difficulties and frustrations of the moment, I still have a dream. It is a dream deeply rooted in the American dream.
"I have a dream that one day this nation will rise up and live out the true meaning of its creed: "We hold these truths to be self-evident: that all men are created equal."
"I have a dream that one day on the red hills of Georgia the sons of former slaves and the sons of former slave owners will be able to sit down together at a table of brotherhood.
"I have a dream that one day even the state of Mississippi, a desert state, sweltering with the heat of injustice and oppression, will be transformed into an oasis of freedom and justice.
"I have a dream that my four children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character.
"I have a dream today.
"I have a dream that one day the state of Alabama, whose governor's lips are presently dripping with the words of interposition and nullification, will be transformed into a situation where little black boys and black girls will be able to join hands with little white boys and white girls and walk together as sisters and brothers.
"I have a dream today.
"I have a dream that one day every valley shall be exalted, every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight, and the glory of the Lord shall be revealed, and all flesh shall see it together.
"This is our hope. This is the faith with which I return to the South. 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 work together, to pray together, to struggle together, to go to jail together, to stand up for freedom together, knowing that we will be free one day.
"This will be the day when all of God's children will be able to sing with a new meaning, 'My country, 'tis of thee, sweet land of liberty, of thee I sing. Land where my fathers died, land of the pilgrim's pride, from every mountainside, let freedom ring.'"
The expansion of liberty did not stop with King's day. Nor did the quest for it. The American story is a story of the relentless advance toward great aspirations. King's story is a story of those aspirations. And it is the story of a hero for all Americans.
