Although Douglass claims a refusal to debate the personhood of slaves, he nevertheless does so by presenting a concrete example of how slaves are treated as individuals: unlike animals, slaves are subject to laws. Douglass uses this fact as a springboard to illustrate the injustice baked into the legal system, where Black people face more severe consequences for the same crimes. Thus, Douglass not only proves the legal personhood of slaves but also demonstrates how their status as legal entities is used to further oppress them.
