About This Work

The Book of Changes, originating in the Western Zhou period (c. 1000 BCE), is unique in world literature: a divination manual that evolved into the foundational text of Chinese cosmology and philosophy. Its 64 hexagrams — each a stack of six broken or unbroken lines — encode a universe of ceaseless transformation, where every situation contains the seed of its opposite and change is the only constant. Confucius studied it obsessively in his later years; Leibniz saw in its binary structure a precursor to his own binary arithmetic that underlies modern computing; Carl Jung found in it a model of synchronicity that challenged Western causality. What remains astonishing: that a bronze-age divination system encodes a worldview of dynamic systems, feedback loops, and emergent properties — concepts at the heart of contemporary complexity science and artificial intelligence.

Why This Matters

This text is part of the living archive of Chinese intellectual achievement — a tradition that produced systematic astronomical observation, mathematical innovation, medical frameworks still in clinical use, and engineering at continental scale, centuries before comparable developments in Europe.

The question "did ancient China have science?" misunderstands what science is. Science is not a single cultural tradition — it is the systematic observation of nature, the rigorous documentation of phenomena, the testing of ideas against evidence, and the building of knowledge across generations. By every one of these measures, the works in this catalogue are scientific. They used different conceptual frameworks — correlative rather than mechanistic, systemic rather than reductionist — but these frameworks produced real knowledge: accurate star catalogues, effective medical treatments, precise calendar computations, and technologies that transformed civilization.
