'Principles of Philosophy' (Latin: Principia Philosophie) is a book by René Descartes, effectively combining his works 'Discourse on the Method' and 'Meditations on First Philosophy'. It was authored in Latin and released in 1644, dedicated to his friend Elizabeth of Bohemia. The French version, titled 'Les Principes de la Philosophie', was published in 1647. The book outlines the principles of nature ... - the laws of physics - as perceived by Descartes, with a notable principle that in the absence of external forces, a body's motion remains constant and in a straight line. Newton borrowed this principle and included it in his works; even today, it's commonly referred to as Newton's First Law of Motion. Descartes intended the book to replace Aristotelian methods in French and British universities. It presents a systematic account of metaphysics and natural philosophy, marking the first truly comprehensive mechanical explanation of the universe.
