《晋书·志·第二十章》
有时是计算过失来定罪，有时是变化法度以遵循常理，有时是依照事实以推究真实情况，有时是有所选择以顺从时宜，有时是加重处罚以防止犯罪，有时是从轻处理以顺从下情。
或计过以配罪，或化略以循常，或随事以尽情，或趣舍以从时，或推重以立防，或引轻而就下。
Sometimes it is calculating negligence to convict, sometimes it is changing laws to follow common sense, sometimes it is according to the facts to infer the real situation, sometimes it is selective to follow the opportune time, sometimes it is severe punishment to prevent crime, sometimes it is lenient to follow the inferior.
