 The amusement of the free man is very different from that of the slave, that of the educated man from that of an uneducated man. This can be seen also in the ancient and recent comedies: in the former, what makes one laugh is obscene language, in the latter, it is rather the innuendos (huponoia), and this difference is not small in view of elegance (euschêmosunê). (IV 8, 1128a20–25)
