In 1829, the abolitionist David Walker published a stunning, poignant appeal to “to the colored citizens of the world.” He urged them to fight against a system of racial slavery and oppression, and to expose that system’s moral bankruptcy. Walker’s plea has since taken shape in the work of some of America’s greatest thinkers, like W.E.B. Du Bois, James Baldwin and Billie Holiday. On this episode redux, a political philosopher reflects on their ideas, their art and their struggles against resignation.
