《宋书·志·卷十三》
现在评论者所肯定的并未亲眼所见，所否定的也不过是虚妄之说，通过争论这些问题以对其他问题产生影响是说不通的，运用现在的认识就背离了古代的看法，不实的成分虽然很多，但片面地坚持一种观点不如兼顾现在的情况为好。
今议者所是不实见，所非徒为虚妄，辨彼骇此，既非通谈，运今背古，所诬诚多，偏据一说，未若兼今之为长也。
What the current commentators affirm has not been seen with their own eyes, and what they deny is just nonsense. It is unreasonable to influence other issues by debating these issues. Using current knowledge deviates from ancient views, although there are many unrealistic elements, it is better to take into account the current situation than to stick to one view.
