《易传·文言传·乾文言》
君子通过学习来积累知识，通过诘疑来辨明是非，以远大作为内心的目标，以仁义作为履行的责任。《易经》说： 飞龙出现在大地上，有利于会见贵族王公。 
君子学以聚之，问以辩之，宽以居之，仁以行之。《易》曰： 见龙在田，利见大人。 
Gentlemen accumulate knowledge through learning, distinguish between right and wrong by questioning, take great cause as the goal of the mind, and take benevolence and righteousness as the responsibility to be practiced. <The Book of Changes> says: Flying dragon appears on the earth, which is favorable to meet with noble princes.
