Jefferson knew that slavery degraded the humanity of those who perpetuated its existence because it necessitated the subjugation of another human being; at the same time, he believed that Black people were an inferior class. This is where Jefferson’s logic falls apart, historian Winthrop D. Jordan wrote in 1968. If Jefferson truly believed that Black people were inferior, then he must have “suspected that the Creator might have in fact created men unequal; and he could not say this without giving his assertion exactly the same logical force as his famous statement to the contrary.”
