It was the Declaration of Independence, not the Constitution, that animated Lincoln’s project to return mid-19th-century America to our “ancient faith.” For Lincoln, the path of salvation for a country torn by contention over slavery ran through the past: “Our republican robe is soiled, and trailed in the dust. Let us re-purify it. Let us turn and wash it white, in the spirit, if not the blood, of the Revolution.”
The Declaration, according to Lincoln, easily could have enunciated the practical reasons for our split from Britain, and left it at that. No ringing philosophical statements, no invocation of “unalienable rights.”
But Thomas Jefferson’s handiwork was meant for the ages. Lincoln praised him for possessing the foresight “to introduce into a merely revolutionary document, an abstract truth, applicable to all men and all times, and so to embalm it there, that to-day, and in all coming days, it shall be a rebuke and a stumbling-block to the very harbingers of re-appearing tyranny and oppression.”
Lincoln made precisely this use of the Declaration. Prior to the passage of the Kansas-Nebraska Act in 1854, overturning the Missouri Compromise and allowing slavery into all the territories if the people wanted it, he referred to the Declaration in public only twice. In the ensuing crisis, it became a staple of his rhetoric.
Lincoln’s historic debates with Illinois Sen. Stephen Douglas, the author of the Kansas-Nebraska Act, were at bottom an argument about the Declaration.
Douglas believed that ultimately the Declaration is a lie…Under his doctrine of “popular sovereignty,” Douglas wanted to allow the extension of slavery in blatant disregard of the belief that “all men are created equal.”
Worse, Douglas and his ilk (Chief Justice Roger Taney and all the apologists for the slave power) fell back on the argument that blacks weren’t men. If so, Lincoln wondered, why did the country permit half a million blacks their freedom? “How comes this vast amount of property to be running about without owners? We do not see free horses or free cattle running at large.
Lincoln lost the 1858 Senate election, of course, but he succeeded ultimately in vindicating the Declaration. It should remain today what Lincoln fought to establish it as: the timeless object for our national aspiration. “They meant to set up a standard maxim for free society,” Lincoln said of the Founders, “which should be familiar to all, and revered by all; constantly looked to, constantly labored for, and even though never perfectly attained, constantly approximated, and thereby constantly spreading and deepening its influence, and augmenting the happiness and value of life to all people of all colors everywhere.”
