Abigail Adams recorded that when her husband and Thomas Jefferson visited Shakespeare’s birthplace, Jefferson fell upon the ground and kissed it and John Adams cut a chip from Shakespeare’s chair. Jefferson and Adams both revered Shakespeare, as did Abigail, and they all understood how necessary it was for a free people to revere what deserves reverence. As this story shows, they also understood that true reverence needs to be complemented by good humored irreverence.

P.G. Wodehouse was one of the best writers in the English language in the 20th century and the funniest. He wrote nearly 100 delightful books, each one of which in perfectly orchestrated sentences, can make you fall laughing out of your beach chair. He became an American citizen in 1955, wrote an autobiography titled “America, I like you.” Read anything Wodehouse. You won’t regret it.

Until the election of 1860, the truths proclaimed in the Declaration of Independence had been the ground of American civic friendship, above all the central truth that all men are created equal. Fidelity to this most American idea held the country together through many divisions since 1776. The Confederate States rejected that idea. America had lost the foundation for civic peace. Ballots gave way to bullets.

Americans are being reminded how fragile and precious an achievement it is to establish the legitimate authority of government through peaceful and free elections. But there would be no ballots without the bullets of 1776. We hold elections in America because, as the Declaration of Independence says, we think “the just powers of government are derived from the consent of the governed.” But what divided the American people from the British Crown and Parliament in 1776 could not be decided by a vote alone.

Marlene Dietrich was born in Berlin in 1901. In 1930, her performance in the film The Blue Angel made her a star. She moved to Hollywood, starred in six films, one of which earned her an Oscar nomination. Many more films would follow. She refused lucrative contracts from Nazi Party officials to be the leading film star of the Third Reich, became an American citizen in 1939, and devoted herself to doing all she could for American troops during World War II.

The son of an Italian immigrant, Vincent Thomas Lombardi was born in Brooklyn on June 11, 1913. He played guard in the famed Seven Blocks of Granite offensive line of Fordham University in the 1930s before going on to become one of the greatest coaches of all time in any sport. His name is synonymous with winning. His steadfast spirit inspired the nation.

We are not born understanding what it means to be an American, understanding the idea of political freedom, or knowing about the American Revolution. We have to learn these things. If we don’t, the American Revolution, political freedom, and Americans will vanish from the earth.

One of the most popular films in Hollywood history, “Casablanca” seems to be composed of one famous line after another. For over 75 years, it has inspired us to stand up and sing in defiance of tyranny and on behalf of the cause of freedom.

More than 4 million visitors come to the Arlington National Cemetery every year from across America and around the world and, unless they have their own personal visit to make, the thing they most want to do is to climb the hill to the high ground of the Memorial Amphitheater and visit the Tomb of the Unknown Soldier.
