The Satyricon of Petronius Arbiter/Chapter 3
CHAPTER THE THIRD. He would not permit me to declaim longer in the portico than he himself had sweat in the school, but exclaimed, “Your sentiments do not reflect the public taste, young man, and you are a lover of common sense, which is still more unusual. For that reason, I will not deceive you as to the secrets of my profession. The teachers, who must gibber with lunatics, are by no means to blame for these exercises. Unless they spoke in accordance with the dictates of their young pupils, they would, as Cicero remarks, be left alone in the schools! And, as designing parasites, when they seek invitations to the tables of the rich, have in mind nothing except what will, in their opinion, be most acceptable to their audience—for in no other way can they secure their ends, save by setting snares for the ears—so it is with the teachers of rhetoric, they might be compared with the fisherman, who, unless he baits his hook with what he knows is most appetizing to the little fish, may wait all day upon some rock, without the hope of a catch.
