The term dates from the mid-19th century in the American context. Advocates for abolition of slavery argued that the institution was contradictory to the United States Declaration of Independence's statements that "all men are created equal" and possessed natural rights to "life, liberty, and the pursuit of happiness." Proslavery opponents countered that the Declaration was a collection of inspirational statements intended for revolution, rather than a concrete set of principles for civil society. Rufus Choate, a Whig senator from Massachusetts, likely brought the term into general discourse in his August 1856 public letter to the Maine Whig Committee. In the letter, Choate expressed fear that antislavery Whigs, inspired by the Declaration's "glittering and sound generalities," would destroy the Union. The letter – and especially Choate's phrase – became the topic of much public debate in the northern press. However, it is unclear whether the phrase was originated by Choate or Franklin J. Dickman, a judge and legal scholar of that era. Abraham Lincoln, in an April 6, 1859 letter to Henry L. Pierce, criticized political opponents of the day who slighted the foundational principles of Thomas Jefferson as "glittering generalities". Lincoln asserted that Jefferson's abstract ideals were not mere rhetoric, but the "definitions and axioms of free society."
