 Intersectionality theory is an especially important recent development in feminist methodology of relevance to philosophy of law. Feminists using an analysis of intersections between race, sex, and other identity categories discern essentialist tendencies that gloss the complexities of identity in the work of both radical and liberal feminists (Crenshaw 2012, Harris 1990). Intersectionality theorizes how locations in multiple socially constructed categories such as gender, race, class, or disability affect how people live (Jones 2013, Haslanger 2012). Theorizing without intersectionality made women of color and other multiply oppressed people invisible; keeping categories such as race and sex separate made it more difficult to achieve justice for persons who were multiply oppressed. Intersectionality creates interlocking and superimposed axes of privilege or disadvantage (Haslanger 2012). An illustration can be found in ways that prison violence arguably tracks intersections between vulnerability and identity categories, with images of female vulnerability both reinforcing sexist thinking and contributing to the oppression inflicted by the racist carceral state (Gilson 2016).
