In this chapter Bettcher examines feminist philosophical engagements with transgender studies. In the first section, she discusses the emergence of trans studies as well as the recent development of trans philosophy within the discipline. The latter makes the question of feminist philosophical engagement more complex. To what extent does the feminist philosophy engage with trans philosophy? To what extent does it merely philosophize about trans phenomena? In the second section, Bettcher considers an approach that adds trans to a longer list of excluded identities, focusing specifically on analytic work designed to answer the question “What is a woman?” Drawing on Crenshaw’s notion of intersectionality, Bettcher raises worries about this sort of approach in both its traditional and ameliorative variations. In the final section, Bettcher considers intersectional approaches to trans oppression/resistance as well as impediments to their pursuit including oppositional starting points, unhelpful models of trans oppression/resistance, and, finally, complexities that arise when considering the intersections of trans and sexist oppressions.
