In 1851, Frederick Douglass publicly challenged the position of William Lloyd Garrison and the American Anti-Slavery Society that the U.S. Constitution was a proslavery document. As an enslaved child, the self-taught Douglass had identified literacy as “the pathway from slavery to freedom.” The same insight prompted the mature author and editor to part ways with Garrisonian moral suasionists in order to join “legal suasionists” like antislavery constitutionalist lawyers Lysander Spooner and William Goodell. From the 1840s through the 1890s, Douglass promoted the legal literacy of everyday African Americans (free and enslaved) while developing his own legal-critical analysis of American racism. Committed to wielding the “forms of law and . . . rules of hermeneutics” on behalf of freedom and equality, Douglass tirelessly challenged the increasingly biopolitical orientation of post-Reconstruction legislation and jurisprudence. From slavery to mass incarceration, Douglass insisted, racism is incompatible with the rule of law.
