In this article, I propose that Simone de Beauvoir'sThe Second Sexinstantiates a version of the endoxic method, a philosophical strategy practiced originally by Aristotle. After summarizing the methodological principles and the philosophical benefits of Aristotle's method, I argue that Beauvoir improves upon Aristotle's endoxic practice through her heightened focus on theendoxaof minority groups, in this case women. Despite this improvement, Beauvoir replicates some of Aristotle's mistakes with her exclusive focus on the experiences of white French women. I address problems of (...) epistemological bias that arise with the endoxic method, and I hypothesize strategies to manage these biases. I conclude that the endoxic method offers a promising resource for feminist philosophers if we retrofit the method to include an intersectional lens and a practice of epistemic humility. My reading of the endoxic method complements feminist scholarship that readsThe Second Sexas a phenomenological investigation. Thus, I suggest that future research exploring the relationship between the endoxic method and phenomenology could generate important insights regarding feminist methodologies and social activism.
