Sexual orientation and how we might understand it is a topic that arouses significant controversy. Is sexual orientation a natural or social phenomenon? Are categories such as 'queer' and 'straight' essential to the human condition or dependent on contingent cultural practices? While such questions have been considered from the perspectives of sociology and gender studies, they remain relatively underexplored from a philosophical standpoint.

In this book, Matthew Andler breaks new ground examining the metaphysics of sexuality. Distinguishing sexual orientation and sexual identity, he asks why only certain aspects of sexuality count as sexual orientations, arguing that sexual dispositions can only become sexual orientations in virtue of being related to heteropatriarchal kinship structures.

He then turns to sexual identity, arguing that the categories 'queer' and 'straight' are grounded in the political function of sexuality cultures as resisting and/or entrenching heteropatriarchal kinship structures. Additionally, he critiques capitalist expropriations of queerness in pinkwashing. He also argues that trans-inclusive interpretations of sexuality categories serve everyone who seeks to build a life outside of the narrow provisions of heteropatriarchal kinship structures.

Sexual Orientation and Identity: A Philosophical Analysis will be of interest to those studying the philosophy of gender, social metaphysics, and gender studies, as well as for anyone interested in the conceptual issues underlying debates concerning gender and social justice.
