 [Huang] once said, “The profession of [studying] the classics is for the ordering of the world (ordering the world).” Therefore, he did not pursue the learning of the petty Confucians but commanded [himself] to study the classics and history. He also said, “Without [such] study, the changes and transformations of principle (i) cannot be verified”. (quoted in Gu Qingmei 1978: 118)
