THE GREATEST SENTENCE EVER WRITTEN

Words that made a nation.

Isaacson is known for expansive biographies of great thinkers (and Elon Musk), but here he pens a succinct, stimulating commentary on the Founding Fathers’ ode to “life, liberty, and the pursuit of happiness.” His close reading of the Declaration of Independence’s second sentence, published to mark the 250th anniversary of the document’s adoption, doesn’t downplay its “moral contradiction.” Thomas Jefferson enslaved hundreds of people yet called slavery “a cruel war against human nature” in his first draft of the Declaration. All but 15 of the document’s 56 signers owned enslaved people. While the sentence in question asserted “all men are created equal” and possess “unalienable rights,” the Founders “consciously and intentionally” excluded women, Native Americans, and enslaved people. And yet the sentence is powerful, Isaacson writes, because it names a young nation’s “aspirations.” He mounts a solid defense of what ought to be shared goals, among them economic fairness, “moral compassion,” and a willingness to compromise. “Democracy depends on this,” he writes. Isaacson is excellent when explaining how Enlightenment intellectuals abroad influenced the founders. Benjamin Franklin, one of the Declaration’s “five-person drafting committee,” stayed in David Hume’s home for a month in the early 1770s, “discussing ideas of natural rights” with the Scottish philosopher. Also strong is Isaacson’s discussion of the “edits and tweaks” made to Jefferson’s draft. As recommended by Franklin and others, the changes were substantial, leaving Jefferson “distraught.” Franklin, who emerges as the book’s hero, helped establish municipal services, founded a library, and encouraged religious diversity—the kind of civic-mindedness that we could use more of today, Isaacson reminds us.

A short, smart analysis of perhaps the most famous passage in American history reveals its potency and unfulfilled promise.
