Elements of the Philosophy of Newton

Elements of the Philosophy of Newton is a book written by the philosopher Voltaire and co-authored by mathematician and physicist Émilie du Châtelet in 1738 that helped to popularize the theories and thought of Isaac Newton. This book, coupled with Letters on the English, written in 1733, demonstrated that Voltaire had moved beyond the simple poetry and plays he had written previously.
A new edition was published in 1745 that contained an initial section on Newton's metaphysics, originally published separately in 1740.
By 1745, when the edition of Voltaire's Éléments was published, the tides of thought were turning his way, and by 1750 the perception had become widespread that France had been converted from erroneous Cartesianism to modern Newtonianism thanks to Voltaire.
Charles Coulston Gillispie says that "Voltaire explained Newtonian science to the educated public more successfully than any other writer, perhaps because he took more pains to understand it."
