This paper develops and defends the view that gender is an identity that we confer upon ourselves. The claim that gender is a self-conferred identity is not novel; but its metaphysics is obscure at best. What exactly is an identity, and how do we manage to confer identities upon ourselves? Furthermore, how does the claim that gender is a self-conferred identity comport with the widely accepted notion that gender is also a social identity, and that social identities are (at least (...) partly) either conferred upon us by others or constituted by the social positions we occupy? This paper articulates a metaphysics for the self-conferred-identity account that addresses these questions. The most important advantage of the view is that, in contrast to other realist theories about the metaphysics of gender, this one transparently offers a basis for assigning first-person authority to people’s judgments about their own gender.
