Éléments de la philosophie de Newton
Voltaire's 1738 popular exposition of Newtonian natural philosophy — the work that introduced Newton to French Enlightenment culture and helped displace Cartesian physics across the Continent
Tradition: French Enlightenment / Newtonian natural philosophy
Newton's natural philosophy — gravitation, optics, the calculus, the empirical method — explained for the educated French-reading public, against the entrenched Cartesianism of the Sorbonne
The Éléments de la philosophie de Newton is Voltaire's 1738 popular exposition of Newtonian natural philosophy — the work that introduced Newton systematically to French Enlightenment culture and helped displace Cartesian physics across the Continent. Written in collaboration with Émilie du Châtelet (whose work on the French translation of the Principia was the more technical companion to Voltaire's popularisation), it covers Newtonian optics, gravitation, the inverse-square law, the calculus, and the empirical-experimental method. The work's polemical edge is directed at the entrenched Cartesianism of the Sorbonne and the Académie des Sciences — Cartesian vortex theory was still the dominant French account of planetary motion when Voltaire wrote — and it positioned Newton as the model of the rational, empirically-grounded natural philosophy that the Enlightenment aimed to extend into every domain of inquiry. The book's influence on the eighteenth-century French scientific establishment was decisive: by the 1750s, Cartesian physics had largely yielded to Newtonian.

School Embodiments
The work defends the Newtonian empirical-experimental method against the Cartesian deductive-systematic alternative; it is foundational French Enlightenment empiricism.
"Newton experiments and reasons from experiments; Descartes hypothesises and reasons from hypotheses. The first method is the proper one for natural philosophy." (Éléments, ch. 1)
Although Voltaire defends empirical method, the mathematical structure of Newtonian physics — and the confidence that nature is mathematically intelligible — is rationalist in the high-Enlightenment sense.
"Nature is written in the language of mathematics; the inverse-square law of gravitation discloses the mathematical structure of the cosmos itself." (Éléments, ch. 7)
The Newtonian universe Voltaire expounds is naturalist — gravitation, optics, motion are governed by natural laws accessible to reasoned inquiry without theological appeal.
"What we have learned about nature, we have learned by observing nature; the appeal to final causes from a creator God belongs to theology, not to physics." (Éléments, ch. 12)
Voltaire's framework is deist: Newton's universe presupposes a creator God whose existence reason discloses, but the natural workings of the universe are autonomous, not requiring constant divine intervention.
"The order of nature is the strongest argument for a divine intelligence behind it; but that order, once established, operates by its own laws." (Éléments, ch. 1)
Voltaire is realist about the Newtonian framework: forces, particles, and laws are real features of the universe, not merely useful mathematical constructions.
"Gravitation is not a mathematical fiction; it is a real force that operates between bodies according to the inverse-square law." (Éléments, ch. 7)
The work's practical-meliorist purpose — make Newtonian natural philosophy available to the educated French-reading public — is pragmatic-realist Enlightenment popularisation.
"What we have here attempted is to bring Newton out of the cloister of the schools and into the conversation of every educated reader." (Éléments, Preface)
The carefully argued metaphysical implications of Newtonian physics — absolute space, absolute time, the nature of forces — anticipate analytical-metaphysical engagement with physics.
"Newton holds space and time to be absolute; Leibniz held them to be relational. The question deserves the most careful consideration." (Éléments, ch. 6)
Internal Tensions
Voltaire's exposition was substantially correct but inevitably simplified — the technical mathematics required for serious Newtonian work was beyond most of his readers and beyond what the Éléments could provide. Émilie du Châtelet's translation of the Principia (published posthumously in 1759) supplied the technical companion. The work's polemical edge against Cartesianism was effective: by the 1750s, the French scientific establishment had substantially adopted Newtonianism.
