A Nation Founded on an Idea

Abraham Lincoln did not invent the idea that the Declaration is the foundation of American political life. But he made it central to how Americans understand their nation.

Lincoln believed that the Declaration was a statement of principles through which the Constitution should be interpreted. In his Gettysburg Address, he famously began with the phrase “Four score and seven years ago” — a reference not to the Constitution (ratified in 1789) but to the Declaration (adopted in 1776). Lincoln was saying that the nation was founded not on a document of government but on a proposition: that all men are created equal.[reference:48]

“The Declaration of Independence... contains the principles of free government, and is the foundation of our political faith.” Abraham Lincoln, 1858

The Declaration as a Weapon Against Slavery

Frederick Douglass, the formerly enslaved abolitionist, used the Declaration as his primary rhetorical weapon. In his famous 1852 speech, “What to the Slave Is the Fourth of July?” Douglass acknowledged the hypocrisy of celebrating freedom in a nation that held millions in bondage. But he did not reject the Declaration. He used it.

The principles of the Declaration, Douglass argued, were “the principles of political freedom and of natural justice.” The nation had failed to live up to them, but the fault was not in the principles — it was in the nation. The Declaration was the standard by which America would be judged, and by which it would eventually be reformed.[reference:49]

The Declaration for Women

In 1848, a group of women and men gathered in Seneca Falls, New York, for the first women’s rights convention in American history. Their Declaration of Sentiments was modeled directly on the Declaration of Independence. It began with the same words — “We hold these truths to be self-evident” — and then listed grievances against the unequal treatment of women.

The Declaration of Sentiments is the clearest evidence that the Declaration of Independence was never meant to be a static document. It was a template — a set of principles that could be applied to new struggles, and a promise that new generations would demand be kept.

The Promissory Note

In his “I Have a Dream” speech, Martin Luther King Jr. described the Declaration as a “promissory note to which every American was to fall heir.” The note, he said, was a promise that all men would be guaranteed the inalienable rights of life, liberty, and the pursuit of happiness. America had defaulted on that promise — but the promise itself remained valid.[reference:50]

King, like Lincoln, understood the Declaration as a founding statement of principle. In a 1961 commencement address, he said that the Declaration “does not say some men [are created equal], but it says all men... It does not say all white men, but it says all men, which includes black men.” The universality of the Declaration was its power.[reference:51]

King was not a revolutionary seeking to overthrow the American founding. He was calling America to live up to it. And the Declaration gave him the language to do it.[reference:52]

“When the architects of our republic wrote the magnificent words of the Constitution and the Declaration of Independence, they were signing a promissory note to which every American was to fall heir.” Martin Luther King Jr., 1963

A Template for the World

The Declaration of Independence was not just an American document. It became a model for liberation movements around the world.

A Living Document

The Declaration of Independence was written in 1776 by men who owned slaves, excluded women from political life, and dispossessed Native Americans. It was a document of its time, and it was flawed.

But it was also a document that contained within itself the tools for its own correction. The phrase “all men are created equal” was a promise that the nation would spend the next two centuries trying to keep. The phrase “governments are instituted among Men, deriving their just powers from the consent of the governed” was a standard that would be used to expand the franchise to women, to Black Americans, and to all citizens.

The Declaration is not a finished achievement. It is a living document — a promise that each generation must decide whether to keep.
