Causality
In the course of Lieh Tzu’s instruction by Hu-ch‘iu Tzŭ-lin, the latter said to him: “You must familiarise yourself with the theory of consequents before you can talk of regulating conduct.” Lieh Tzŭ said: “Will you explain what you mean by the theory of consequents?” “Look at your shadow,” said his Master, “and then you will know.” Lieh turned and looked at his shadow. When his body was bent, the shadow was crooked; when his body was up right, the shadow was straight. Thus it appeared that the attributes of straightness and crooked ness were not inherent in the shadow, but corre sponded to certain positions of the body. Like wise, contraction and extension are not inherent in the subject, but take place in obedience to external causes. Holding this theory of consequents is to be at home in the antecedent. Kuan Yin spoke to the Master Lieh Tzŭ, say ing: “If speech is sweet, the echo will be sweet; if speech is harsh, the echo will be harsh. If the body is long, the shadow will be long; if the body is short, the shadow will be short. Reputa tion is only an echo, external conduct only a shadow. “Hence the saying: Heed your words, and they will meet with harmonious response; heed your actions, and they will find agreeable accord.’ Therefore, the Sage observes the issue in order to know the origin, scrutinises the past in order to know the future. Such is the principle whereby he attains foreknowledge. “The standard of conduct lies with one’s own self; the testing of it lies with other men. We are impelled to love those who love us, and to hate those who hate us. T‘ang and Wu loved the Empire, and therefore each became King. Chieh and Chou hated the Empire, and therefore they perished. Here we have the test applied. He who does not follow Tao when standard and test are both clear may be likened to one who, when leaving a house, does not go by the door, or, when travelling abroad, does not keep to the straight road. To seek profit in this way, is it not a thing that is impossible? “You may consider the virtues of Shên Nung and Yu Yen, you may examine the books of Yii, Hsia, Shang and Chou, you may weigh the utterances of great teachers and sages, but you will find no instance of preservation or destruction, fullness or decay, which has not obeyed this supreme Law.”
