I Ching's influence

As an important component of Chinese traditional culture, the I Ching's influence throughout history has been profound. The I Ching (Yì Jīng), or Classic of Changes, which dates from over 3,000 years ago, is believed to be one of the world's oldest books. The two major branches of Chinese philosophy, Confucianism and Taoism have common roots in the I Ching.

From its mythological origins in prehistory (see Fu Xi) and the earliest dates of recorded history in China, the I Ching has been added to by a succession of philosophers, scholars and rulers. Thus, it reflects a thread of thinking and a common cosmology that have been passed through successive generations. In addition to the I Ching's broadly recognized influence on Confucianism and Taoism, it has been shown to have influenced Chinese Buddhism. Fazang, patriarch of the Huayan school, is believed to have drawn on a mode of thought derived from the I Ching.

One of the earliest versions of the I Ching (called, Zhou I, or Changes of Zhou) was the oracle of the Zhou. It played a role in their overthrow of the Shang dynasty by Zhou King Wu in 1070 BCE. An account of Wu's conquest tells of a solar eclipse believed by the King to be an omen from Heaven to march against the Shang. This account has been matched with a solar eclipse that occurred on June 20, 1070 BCE. Thus, the earliest layer of the I Ching has been shown to preserve a hidden history that went undetected for three millennia. The Zhou Yi has been called one of the most important sources of Chinese culture. It has influenced fields as varied as mathematics, science, medicine, martial arts, philosophy, history, literature, art, ethics, military affairs and religion.

Joseph Campbell describes the I Ching as "an encyclopedia of oracles, based on a mythic view of the universe that is fundamental to all Chinese thought."
