 Second, since blacks were humans, Douglass argued they were entitled to the natural rights that natural law mandated and that the United States recognized in its Declaration of Independence and Constitution. Slavery subverted the natural rights of blacks by subjugating and brutalizing them: taking men and turning them, against God’s will and nature, into beasts. Third, as an affront to natural law, slavery contradicted God’s law. Douglass cited biblical passages and interpretations popular with abolitionists. As a witness and participant of the second Great Awakening, he took seriously the politicized rhetoric of Christian liberation from sin, and, as with other abolitionists, saw it intrinsically wrapped up with liberation from slavery, and indeed national liberation. Fourth, he argued that slavery was inconsistent with the idea of America, with its national narrative and highest ideals, and not just with its founding documents. Fifth, drawing on the ideas of manifest destiny, as well as the idea of natural law realized in historical progress, he argued that slavery was inconsistent with development: moral, political, economic, social, and ultimately historical. America was on the wrong side of history on the question of slavery.
