For Chinese people, The Book of Changes is the source of all philosophy. When you study Zeng Guofan, Xue Yangming, Confucius and Laozi, if you go deeper, you will find that their source is in the Book of Changes. The concepts in the Book of Changes are equivalent to the basics of music, writing, or mathematics. It is the 1]1 = 2 of them.

It is the earliest of all Chinese classics, and it is the "prince" of all texts. Any other Chinese book is directly or indirectly affected by it, and so they are not one hundred percent original. It is the one original Chinese text, it has no other books to refer to, its only reference is nature.

In the case of Laozi's Tao Te Ching, his thought is almost entirely derived from the Book of Changes. The idea of "the movement of the Dao proceeds by contraries, weakness marks the course of Dao's mightiest deeds" is obviously derived from the Book of Changes.

As for Confucius; Historical Records recorded that he read Book of Changes. When he talks of "turning the slips three times", he is talking about the ropes of the bamboo slips that were used for the pages of early books. In The Analects, it is recorded he said, 'If some years were added to my life, I would devote fifty to the study of the I Ching, and then I might come to consider myself virtuous'. This means that if he could have studied The Book of Changes for a few more years, his accomplishments would have been even deeper.
