Descartes's textbook, written to replace the Aristotle taught in the schools. Part one restates the metaphysics of the Meditations in short numbered articles. Part two argues that matter is nothing but extension, that there is no void, and states the laws of motion and the conservation of quantity of motion. Part three builds a universe of vortices, with the planets carried around the sun by a swirling fluid and stars as the centres of other systems. Part four explains the earth, magnetism, fire, glass and the senses on the same mechanical principles.
