《宋史·列传·卷一百八十六》
有的抑制，有的放纵；有的给予，有的削夺；有的推进，有的退后；有的细微，有的显著；而完全根据义理安排，文辞质量的适中，宽泛猛烈的合宜，是与非的公道，成为判断、权衡事物的标准，推测揣度道理的准则。
或抑或纵，或予或夺，或进或退，或微或显，而得乎义理之安，文质之中，宽猛之宜，是非之公，乃制事之权衡，揆道之模范也。
Some are inhibitions, while others are indulgences. Some are givings, while others are deprivations. Some are advances, while others are retreats. Some are slight, while others are evident. To completely arrange according to righteousness, quality of literature, appropriateness of generosity and violence, and fairness of right and wrong has become the standard for making judgments and weighing matters and the principle for inferring and conjecturing principles.
