Abstract

In this essay, I explore the historical challenge that Abraham Lincoln posed to Stephen
Douglas  at the fifth debate in Galesburg. During an argument regarding the morality of
slavery and the meaning and significance of the American regime, Douglas contended that
the nation was legally founded on white supremacy. Lincoln, however, affirmed that based
on all available historical evidence, the Founders intended to include all humans when they
said in the Declaration of Independence, based on their understanding of natural law, that
all men are created equal. To demonstrate his confidence in this belief, Lincoln challenged
Douglas  to provide primary source evidence that anyone, prior to the 1850s, ever said
that the black race was not included in the Declaration. Studying Lincoln's natural law
challenge and the responses it received offers a new perspective on the importance of the
original meaning of the Declaration's equality principle, grounded in the law of nature, as
well as how Lincoln thought about that principle-particularly in contrast to rivals like
Douglas  and Roger Taney.

1. Introduction
     Much has been written about Abraham  Lincoln's famous Freeport Question at the
1858 joint debates with Stephen A. Douglas. Less recognized is what might be called
Lincoln's Galesburg Challenge, which Lincoln presented to Douglas at the fifth debate
in Galesburg and then repeated at the seventh and final debate in Alton. In the midst
of an argument regarding the morality of slavery and the meaning and significance of
the American  regime, Douglas contended that the nation was founded on the principle
of white supremacy, and  that when the Founders  said all men are created equal in
the Declaration of Independence, they meant only white men.  Lincoln, on the other
hand, affirmed that based on all available historical evidence, Americans should rest
assured that the Founders intended to include all human beings-and  all races-in the
Declaration's equality principle, based in large part on their commitment to natural law
legal reasoning. To demonstrate his confidence in this belief, Lincoln challenged Douglas
to provide primary source evidence that anyone, prior to the 1850s, ever said that the black
race was not included in the Declaration. Here is the crux of the challenge, as stated by
Lincoln at the Galesburg debate in October 1858:
     I believe the entire records of the world, from the date of the Declaration of
     Independence  up to within three years ago, may be searched in vain for one
     single affirmation, from one single man, that the negro was not included in the
