《文心雕龙·知音》
由此看来，见识高超崇古非今的人就是秦始皇和汉武帝这样的人；才华卓越而喜欢抬高自己、压低别人的人就是班固和曹植这样的人；毫无文才而误信传说、不明真相的人就是楼护这类人。刘歆看了扬雄的《太玄》后说： 我怕后人用它来盖酱瓮。 这难道是多余的感叹吗？
故鉴照洞明，而贵古贱今者，二主是也；才实鸿懿，而崇己抑人者，班、曹是也；学不逮文，而信伪迷真者，楼护是也；酱瓿之议，岂多叹哉！
From this it would seem that such persons as Shih Huang Ti and Han Wu Ti were acute in their judgments, but looked down upon the present and admired the past; that such persons as Ban Ku and Ts‘ao Chih were brilliant in talent, but liked to exalt themselves and depreciate others; and that such persons as Lou Hu were without literary talent, but accepted hearsay and were unable to detect the truth. Liu Hsin, after reading the T'ai Hsüan of Yang Hsiung, said, "I am afraid that after ages will use it to cover jars of sauce"; and were these not superfluous regrets?
