Lionel Giles's notes
Mei Yao-ch‘ên has rather an interesting note: 鬼神之情可以筮卜知形氣之物可以象類求天地之理可以度數驗唯敵之情必由間者而後知也 “Knowledge of the spirit-world is to be obtained by divination; information in natural science may be sought by inductive reasoning; the laws of the universe can be verified by mathematical calculation: but the dispositions of an enemy are ascertainable through spies and spies alone.”
