Deep in the forest a call was sounding, and as often as he heard this call, mysteriously thrilling and luring, he felt compelled to turn his back upon the fire and the beaten earth around it, and to plunge into the forest, and on and on, he knew not where or why.
森林深处响着一个呼唤;每当听到那神秘、震颤而诱人的声音,他便不由自主地背离篝火和周围踩实的土地,投入森林,不停向前,却不知道去往何处,也不知道为什么。
— Jack London · The Call of the Wild (1903) · Chapter VI · For the Love of a Man —
