About This Work
The Mohist Canon (4th–3rd centuries BCE) contains the earliest treatment of physical science in China. Its chapters on optics, mechanics, and geometry document shadow formation, pinhole imaging, mirror reflection, lever mechanics, pulley systems, and center of gravity. The Mohists' deductive approach — defining terms and drawing conclusions — anticipated key elements of scientific methodology.

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.
