“Indeed, it is not uncommon for slaves even to fall out and quarrel among themselves about the relative goodness of their masters, each contending for the superior goodness of his own over that of the others.”
This line has been taken from “Narrative of
the Life of Frederick Douglass; An American
Slave” by Frederick Douglass himself. He was an
African-American social reformer and a writer. He has effectively used litotes to stress that his point that even slaves used to seek dominance over other slaves by stressing the point that their respective masters were much better than those of the other slaves.
