What was voted on July 2 was, however, really decided on July 1. But on June 28, Congress considered Jefferson's draft of the Declaration, so was the die then cast? Or was it cast on June 10, when Congress voted that "a committee be appointed to prepare a declaration"? The Declaration was first actually declared -- read aloud to a crowd (at the State House, now Independence Hall) -- on July 8.

De Bolla says that unlike certain events, such as an earthquake or the beheading of a monarch, the birth of a nation has "a different kind of temporality," one constructed as a tradition. This is true even of the United States, which did not, like Germany and France, emerge over millennia from history's mists.

Fifty years later, less than two months before his (and John Adams') death on July 4, 1826, Jefferson was determinedly protective of his reputation as (he directed his tombstone to declare this) "author" of the Declaration. Still, he candidly acknowledged that it "was intended to be an expression of the American mind," not "aiming at originality of principle or sentiment." Hence, "all its authority rests then on the harmonizing sentiments of the day."

Certain politically charged rhetorical tropes were then society's common property. Writing shortly before his death, Jefferson affirmed his belief that "the mass of mankind has not been born with saddles on their backs, nor a favored few booted and spurred, ready to ride them legitimately, by the grace of God." Those words were as stirring then as they had been when one of Oliver Cromwell's soldiers declared from the scaffold, "I never could believe that Providence had sent a few men into the world, ready booted and spurred to ride, and millions ready saddled and bridled to be ridden."

What de Bolla calls "the intricate history of the nation's founding document" does not and should not inhibit Americans from asserting the truth that their nation originated on July 4, 1776. They hold that to be a self-evident truth, which means they have decided to believe it, thereby making it a self-validating tradition. So there.
