I love watching the brides pose for photos by the Lincoln Memorial and the teenagers wriggle through TikTok choreography near the Washington Monument. Their modern hopes breathe life into the centuries-old wisdom of our capital city.

I have lived in Washington DC for years and still can’t get enough of it. On sunny Saturday morning walks, my pace is casual, but the insights are profound. DC is a living lesson about what George Washington described as “the last great experiment for promoting human happiness.” The Inauguration brings new people to Washington DC and I hope they will love and learn from the city as much as I do.

One of my favorite monuments is near the Capitol. Two iron cranes stand together. Their wings thrust upward, and barbed wire falls from their beaks. Around them is a complicated mix of names: Japanese Americans who died fighting for us in World War II, and the internment camps to which their families and friends had been forced. Yet I am fiercely proud to be an American when, amidst these names, I read President Reagan’s words: “Here we admit a wrong. Here we affirm our commitment as a nation to equal justice under the law.” Few countries I’ve lived in have the strength to admit such a grave national error.

That urge for improvement is in our national genes. As the Constitution states, we’re constantly trying to “form a more perfect union.”

Sure enough, a few miles away under a white marble dome stands a statue of Thomas Jefferson. He, too, speaks to us of striving for perfection: “…Laws and institutions must go hand in hand with the progress of the human mind. As that becomes more developed, more enlightened … institutions must advance also to keep pace with the times.”

While I respect the somber challenge of those words, I love his next, more whimsical, sentence: “We might as well require a man to wear still the coat which fitted him when a boy as civilized society to remain ever under the regimen of their barbarous ancestors.”

From a breezy hill in northeast Washington DC, President Lincoln also challenges us. It’s the cottage where he and his family escaped the city’s summer heat, though Lincoln daily commuted to the White House. His dusty horseback ride revealed the stakes of the Civil War: wounded soldiers bumping along in ambulances and former slaves surviving in hastily built camps after escaping behind Union lines.

Lincoln welcomed allies and adversaries alike to the cottage for advice, sometimes looking out from the veranda over the not-yet-completed Capitol and Washington Monument. As a modern visitor 150 years later, I can stand in the same place. The buildings are completed. But which of Lincoln’s hopes and fears are still in progress?

At a newer memorial, Martin Luther King, Jr offers optimism about the timescale of our national effort: “We shall overcome because the arc of the moral universe is long, but it bends towards justice.”

At an even newer memorial closer to the Capitol, President Eisenhower puts a worldwide spin on our work of becoming a more perfect union: “We look upon this shaken earth, and we declare our firm and fixed purpose – the building of a peace with justice in a world where moral law prevails.”

Strolling through the city, I love listening to leaders from different periods of our great experiment. I hope our elected representatives will as well.
