Plato,
Laws — Book XII
(1875)
“ And ought not the interpreters, the teachers, the lawgivers, the guardians of the other citizens, to excel the rest of mankind, and perfectly to show him who desires to learn and know or whose evil actions require to be punished and reproved, what is the nature of virtue and vice? Or shall some poet who has found his way into the city, or some chance person who pretends to be an instructor of youth, show himself to be better than him who has won the prize for every virtue? ”
