Abstract
This article outlines various philosophical conceptions of gender. I first explain two basic approaches: first, that gender is a social role or status that is imposed on individuals by third‐person institutional structures; and secondly, that gender is a matter of first‐person identifications, behaviors or choices. Next, I examine the notion of gender essentialism. Is gender is feature of persons that is essential to an individual being the person she is? Is there a “kind essence” or “group essence” that individuals have to instantiate in order to be members of gender groups? Finally, I explain the related debate over the unification of gender categories. Realists argue that explaining group membership requires that we posit a universal, for instance, a single property “womanness” that all members of the group “women” share. Nominalists argue that weaker devices such as linguistic categorization or resemblance are adequate to unify individuals with different characteristics into the group. For nominalists, diversity within groups does not entail that groups are a myth.
