August 28 marked the 50th anniversary of the 1963 March on Washington. Martin Luther King Jr.'s speech at that great rally is rightly honored as one of the greatest speeches in American history. All Americans recognize the soaring rhetoric of the final portion of the speech, where King speaks of a dream of an America without legal discrimination or racial prejudice. But the first part of that speech, wherein King speaks of the Declaration of Independence and Constitution, is not as well-known but deserves to be. That portion demonstrates King's commitment to the conception of justice held at the American founding.
