Rare books Descartes, René. Principia Philosophiae. Amsterdam: L. Elzevir, 1644.
First edition of this monumental system of the world, the most comprehensive of all of Descartes’ works. In Part I, Descartes sets out the basic principles of his method. Part II is devoted to the nature of the physical world. Descartes identified space matter with space, and believed that vacuum is impossible. According to Descartes, matter is infinitely extensible and infinitely divisible. Parts III and IV contain the first serious attempt at a mechanical explanation of the solar system and the origin of Earth.
