In Book V, Rousseau turns to the education of Sophie, Emile's wife-to-be. Rousseau begins his description of Sophie, the ideal woman, by describing the inherent differences between men and women in a famous passage: In what they have in common, they are equal. Where they differ, they are not comparable. A perfect woman and a perfect man ought not to resemble each other in mind any more than in looks, and perfection is not susceptible of more or less. In the union of the sexes each contributes equally to the common aim, but not in the same way. From this diversity arises the first assignable difference in the moral relations of the two sexes. For Rousseau, "everything man and woman have in common belongs to the species, and ... everything which distinguishes them belongs to the sex". Rousseau states that women should be "passive and weak", "put up little resistance" and are "made specially to please man"; he adds, however, that "man ought to please her in turn", and he explains the dominance of man as a function of "the sole fact of his strength", that is, as a strictly "natural" law, prior to the introduction of "the law of love". Rousseau's stance on female education, much like the other ideas explored in Emile, "crystallize existing feelings" of the time. During the eighteenth century, women's education was traditionally focused on domestic skills—including sewing, housekeeping, and cooking—as they were encouraged to stay within their suitable spheres, which Rousseau advocates. Rousseau's brief description of female education sparked an immense contemporary response, perhaps even more so than Emile itself. Mary Wollstonecraft, for example, dedicated a substantial portion of her chapter "Animadversions on Some of the Writers who have Rendered Women Objects of Pity, Bordering on Contempt" in A Vindication of the Rights of Woman (1792) to attacking Rousseau and his arguments. When responding to Rousseau's argument in A Vindication of the Rights of Woman, Wollstonecraft directly quotes Emile in Chapter IV of her piece: "Educate women like men," says Rousseau [in Emile], "and the more they resemble our sex the less power will they have over us." This is the very point I aim at. I do not wish them to have power over men; but over themselves. French writer Louise d'Épinay's Conversations d'Emilie made her disagreement with Rousseau's take on female education clear as well. She believes that females' education affects their
