While in common parlance the word gender often serves as a kid-friendly synonym for sex, in feminist and academic discussions, the two are often seen as conceptually distinct. A rough and hasty description of the sex-gender distinction might say that sex is a biological given, gender is a social construction, and never the twain shall meet. However, even if we grant the sex-gender distinction (and a number of feminists do reject it for a variety of reasons), it remains far from obvious what, precisely, gender is, what it means for gender to be socially constructed, or what we should make of gender anyway.
Fortunately, feminists and philosophers have recently taken interest in the metaphysics of gender. This LibGuide serves as a selective bibliography on some of the scholarly work being done in this fascinating and important field of inquiry. A companion subject post on this topic is forthcoming.
For introductory material on the philosophy of gender and feminist philosophy, check out these articles from the Stanford Encyclopedia of Philosophy, which also provides extensive bibliographies of their own that are worth exploring:
Additionally, the following bibliography identifies sources (within and without philosophy) on matters pertaining to trans genders, the lived experiences of transfolk, and intersectionality, and should prove a valuable resource for those interested in the metaphysics of gender:
