The I Ching in Western Thought

The I Ching (易經, Book of Changes) is more than a divination manual — it is a 3,000-year-old philosophical text that quietly shaped some of the most important Western thinkers of the 20th century. These essays trace its influence on psychology, mathematics, and physics.
