 Sister Juana Inés de la Cruz (1651–1695) was not allowed to enroll in the Royal and Pontifical University of Mexico because she was a woman. However, she became world-renowned for her wisdom and literary talent. Although Juana Inés de la Cruz was not a philosopher by trade, her writings contain elements of philosophy, from stoicism and hermeticism to post-Cartesian philosophy. Her long poem Primero sueño (1692) is an erudite reflection on epistemology and theology based on several classical and contemporary works. Juana Inés de la Cruz is also well-known as an early feminist who described the unfavorable conditions under which women were forced to produce their own philosophy. Her “Respuesta a Sor Filotea de la Cruz” (1691) is a feminist reflection avant la lettre in which she argues that men and women should be allowed to develop fully under the same conditions. In that brilliant and erudite text, she famously claims that “if Aristotle would have been a cook, he would have written even more”.
