  In this chapter, she argues against some of Newton's followers who aimed to universalize Newton's attraction. While Du Châtelet argues that Newton's theory of attraction is better than Descartes' vortices at explaining the effects of gravity, and that Newton's theory of attraction can satisfactorily explain a wide range of other phenomena such as tidal movements, the rotation of the earth, and irregularities in the movement of the moon, she criticizes Newton's disciplines for extending Newton's theory of attraction too far. In one especially interesting section, she focuses on the Newtonian theories (IP §389–92) of John Freind (1675/76–1728) and John Keill (1671–1721).
