On Martin Luther King Jr. Day, we remember a man whose political, intellectual, and moral leadership changed the world. We also tend to do a lot of quoting. With good reason: King's speeches, sermons, and letters are generally acknowledged to have been among the greatest examples of spiritual oratory, political theory, and just plain writing in all of history.
But they're not just history: His prescient observations on everything from poverty to technology feel as relevant today as they did 50 years ago.
Reading or hearing them again is a reminder of King's genius, his compassion, his erudition, his achievements. They're also a reminder that his struggle—the work, as he might have said, of bending the arc of history toward justice—must continue.
