《论衡·卷十二·谢短篇》
儒生不能对古今的事都了解，只想各自分别讲述他们擅长的经书，可是经书上的事情和道理是类似的，如果说可以不了解古今的事，这才是以无知为贵！
儒不能都晓古今，欲各别说其经；经事义类，乃以不知为贵也？事不晓，不以为短！
Confucians cannot understand the things of ancient and modern times, but only want to tell their own strengths on the classics, but the affairs and principles in the classics are similar. If they can be said to not understand the things of ancient and modern times, this would be valuing ignorance!
