# Quote — Jean Jacques Rousseau, Emile; or On Education

> With the help of dice Descartes made heaven and earth; but he could not set his dice in motion, nor start the action of his centrifugal force without the help of rotation. Newton discovered the law of gravitation; but gravitation alone would soon reduce the universe to a motionless mass; he was compelled to add a projectile force to account for the elliptical course of the celestial bodies; let Newton show us the hand that launched the planets in the tangent of their orbits.
