Gender Without Identity offers an innovative and at times unsettling theory of gender formation. Rooted in the metapsychology of Jean Laplanche and in conversation with bold work in queer and trans studies, Avgi Saketopoulou and Ann Pellegrini jettison "core gender identity" to propose, instead, that gender is something all subjects acquire -- and that trauma sometimes has a share in that acquisition. Conceptualizing trauma alongside diverse genders and sexualities is thus not about invalidating transness and queerness, but about illuminating their textures to enable their flourishing.
