LIX. Of rhetoric he speaks of six species. For when orators exhort the people to make war upon or to form alliances against any one, this species of oratory is called exhortation. When they persuade the people not to make war, or to form alliances, but to keep quiet, this kind of rhetoric is called dissuasion. The third species of rhetoric, is when any one says that he has been injured by some one else, and impeaches that person as guilty of many crimes; for this species is called accusation. The fourth kind of rhetoric is called defence, when a man shows that he has done no wrong, and that he is not guilty of anything out of the way. Such a kind of speech they call a defence. The fifth species of rhetoric, is when any one speaks well of another, and shows him to be virtuous and honourable; and this kind is called encomium. The sixth species, is when any one shows that another person is worthless; and this kind is called blame. So that rhetoric is divided into encomium and blame, exhortation and dissuasion, accusation and defence.
