Mathematician and Philosopher

This chapter traces the early life of mathematician and philosopher Elisabeth Ferrand. It documents her interest in the sciences from an early age as well as her accomplishment as a mathematician, in which she won the respect of various members of the Bernoulli dynasty in Basel. A professed Newtonian before Mme Du Châtelet, she had also been taught by her longtime friend Lévesque de Pouilly, who was readily acknowledged by Voltaire as the man who introduced Newton's thoughts into France. The chapter also discusses Ferrand's support for Newton and how she became an early believer in the law of attraction. In a portrait by Quentin de La Tour she chose to be depicted “meditating on Newton.” For Ferrand, as the chapter reveals, being a Newtonian meant appreciating elegant reasoning, understanding math and maybe even calculus (although this is not certain), accepting the law of attraction, and embracing an orderly, lawful view of nature. Ultimately, the chapter presents Ferrand's study, as an epistemologist, about human cognition by analyzing separately what each of the five senses contributed to it.
