Thou knowest not what virtue is, neither hast thou taken council of the wise. And therefore it is that from ignorance, and childishness thou destroyest the lower animals. Say, who art thou, and what for hast thou come to the forest devoid of humanity and human beings? And, O foremost of men, tell thou also, whither thou wilt go to-day. Further it is impossible to proceed.
