  While Du Châtelet's primary interest was in natural philosophy, she also had interests in ethics (translating of portions of Mandeville's Fable of the Bees), theology and the Bible (writing a book titled Examens de la Bible), and the source of human happiness (writing a semi-autobiographical book, Discours sur le bonheur). Her non-scientific work occasionally touched on the subject of women's social roles and their education.
