...beyond peoples of black West Africa to the south there is no civilization in the proper sense. There are only humans who are closer to dumb animals than to rational beings. They live in thickets and caves, and eat herbs and unprepared grain. They frequently eat each other. They cannot be considered human beings. Therefore, the Negro nations are, as a rule, submissive to slavery, because (Negroes) have little that is (essentially) human and possess attributes that are quite similar to those of dumb animals, as we have stated.
