“Tell ’em about the dream, Martin.” Such was the entreaty that, according to popular lore, the gospel singer Mahalia Jackson shouted to Martin Luther King Jr. on August 28, 1963.¹ The civil rights leader was two-thirds through the speech he was delivering on the steps of the Lincoln Memorial. King had spoken about his dream in other contexts but had not included the idea in his prepared texts for this speech. We can be grateful then that King, responding to Jackson or some other grace-touched inspiration, went off script and spoke words that, though often scorned at the time, have ever since resounded deep in the American soul:

I say to you today, my friends, so even though we face the difficulties of today and tomorrow, 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.”
