Trans Women Are (or Are Becoming) Female: Disputing the Endogeneity Constraint

Abstract

AbstractThe dispute between the transgender-rights movement and “gender-critical” activists represents a stark division in British public discourse. Although the issues of contention are numerous and require their own philosophical treatment, a core metaphysical concern underlies them. Gender-critical activists, such as Kathleen Stock, tend to argue that recognizing trans women as women requires erasing the category of biological sex. This implies that all trans women are male, and thus recognizing them as women rips female biology from the root of the category “woman.” In this article, I argue that this view is mistaken. As exogenously produced sex characteristics should count toward a person's sex classification, all trans women are (or are becoming) female.
