《宋史·列传·卷一百五十三》
近来忽然创立道学之目，郑丙首唱，陈贾附和，官居要职者暗中相互传授，见到士大夫稍稍致力于洁身自好，粗略能坚持操守，就以道学之名强加于他，几乎如吃菜事魔，影迹犯败之类。
近忽创为 道学 之目，郑丙唱之，陈贾和之。居要路者密相付授，见士大夫有稍务洁修，粗能操守，辄以道学之名归之，殆如吃菜事魔、影迹犯败之类。
Recently, Daoism has been established suddenly. Zheng Bing made the first proposal and Chen Jia seconded it. Those who hold important positions secretly teach each other. When they saw that the literati and officials devoted themselves to self-improvement and could roughly uphold their principles, they imposed the name of Daoism on them, which was almost like the case of eating a vegetarian meal to worship the devil or being haunted by a ghost.
