Must I argue the wrongfulness of slavery? Is that a question for Republicans? Is it to be settled by the rules of logic and argumentation, as a matter beset with great difficulty, involving a doubtful application of the principle of justice, hard to be understood? What do the rhetorical questions in the excerpt suggest? Douglass does not want to discuss slavery further. Slavery is a highly divisive and complicated issue. Douglass is uncertain about slavery’s wrongfulness. The wrongfulness of slavery should be obvious.
