Events in honor of the 40th anniversary of the March on Washington got underway Friday, including a ceremony at the steps of the Lincoln Memorial.
It was on those granite steps, on a hot summer day before a crowd of about 250,000, that King delivered his eloquent demand of justice for all.
On Aug. 28, 1963, King said "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 my four little 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.''
Those words are not forgotten, said his son, Martin Luther King, III, in an Associated Press interview. He said, "I do think people remember because they resonate so clearly.''
But King said the appeal his father made so many years ago has not yet been fully embraced. He said, "Components of the dream have been realized, but the entire vision of freedom, justice and equality for all humankind has not been realized yet.''
King planned to join others at a series of teach-ins Saturday before a rally on the spot where his father spoke to the hundreds of thousands lined up along both sides of the Reflecting Pool.
