《文心雕龙·诸子》
但是，鬻熊仅仅是文王的朋友，老子却是孔子的老师；两位圣人和两位贤人同时，而所写的书或成为经，或成为子，俨然是两类不同的著作了。
然则鬻惟文友，李实孔师，圣贤并世，而经子异流矣。
However, Yi Xiong was only a friend of King Wen, while Lao Zi was Confucius's teacher; two saints and two worthy men lived at the same time, and their books became either classics or philosophies, which were obviously two different types of works.
