The Huainanzi has in recent years been recognized by scholars as one of the seminal works of Chinese thought at the beginning of the imperial era, a summary of the full flowering of early Taoist philosophy. This book presents a study of three key chapters of the Huainanzi, "The Treatise on the Patterns of Heaven," "The Treatise on Topography," and "The Treatise on the Seasonal Rules," which collectively comprise the most comprehensive extant statement of cosmological thinking in the early Han period.

Major presents, for the first time, full English translations of these treatises. He supplements the translations with detailed commentaries that clarify the sometimes arcane language of the text and presents a fascinating picture of the ancient Chinese view of how the world was formed and sustained, and of the role of humans in the cosmos.
