Mathematical Principles of Natural Philosophy

Newton’s three-book treatise states the laws of motion and the law of universal gravitation, then shows that the same mathematics governs a falling apple, the moon, the planets, the tides and the comets — deriving Kepler’s empirical rules as consequences rather than accepting them as descriptions. Its method mattered as much as its results: a small set of axioms, geometric proof, and quantities inferred from observation, which is the template the physical sciences have used ever since.

Why it’s on the list: Section V runs the Western canon in rough chronological order and does not separate science from political philosophy — Newton sits between Descartes and Darwin, which is Li Lu’s way of saying the scientific method is part of the same inheritance as Locke and Mill.

Where I saw it: Li Lu’s Recommended Book List, entry 17 of section V, given with no edition or year. Full transcription: Li Lu’s Recommended Book List.
