Zhu Xi’s criticisms of Cheng-Shi-Yi-Zhuan seem to be diverse and inconsistent. Further analyses, however, show the contrary. To put it very briefly, Zhu Xi’s complaints were mainly due to Cheng Yi’s failure to bring about a coherent theory that can integrate xiang-shu, yi-li, and shi-fa, as well as his lack of awareness of the significance of such an integration. The reason why Cheng Yi failed in both regards was in turn due to his ignorance of the theoretical roles Shao Yong’s xian-tien-yi-xue can play. By demonstrating what those theoretical roles are and why they are so important to Zhu Xi, this paper explicates Zhu Xi’s own understanding of the Book of Changes.
