The literature on the metaphysics of gender is partially marked by a tension between conceptions that understand gender categories as importantly at least partly self-determined identities and those that understand them as social or cultural categories imposed upon others as a tool of oppression. I argue that this tension can be mediated by understanding gender categories as essentially contested. I then draw on “radical functionalism” to argue that, while, divorced of context, competing conceptions can simultaneously explicate an essentially contested concept, (...) within context, some conceptions better meet background purposes underlying the use of the concept than others.
