中 庸 Zhongyong – The Doctrine of the Mean

故君子尊德性而道問學，致廣大而盡精微，極高明而道中庸。溫故而知新，敦厚以崇禮。

原文 105

Therefore, the superior man honors his virtuous nature, and maintains constant inquiry and study, seeking to carry it out to its breadth and greatness, so as to omit none of the more exquisite and minute points which it embraces, and to raise it to its greatest height and brilliancy, so as to pursue the course of the Mean. He cherishes his old knowledge, and is continually acquiring new. He exerts an honest, generous earnestness, in the esteem and practice of all propriety.

Legge XXVII.6.

他温习已有的知识，进而能发现新的所不知的，为人忠厚笃实而崇尚礼仪。因此，居于高位不致骄傲，处于下位不会违背上级。国家清平，他的话语足以使国家兴盛；国家腐败黑暗，他保持沉默足以安身。《诗经·大雅·丞民》上说：“既明白整理，又聪明智慧，自身安全，足以保证。”就是说的这个道理吧！
