The Palgrave Handbook of Sexual Ethics is a comprehensive collection of recent research on the ethics of sexual behavior, representing a wide range of perspectives. It addresses a number of traditional subjects in the area, including questions about pre-marital, extra-marital, non-heterosexual, and non-procreative sex, and about the nature and significance of sexual consent, sexual desire, and sexual activity, as well as a variety of more recent topics, including sexual racism, sexual ableism, sex robots, and the #metoo response to sexual harassment. Each chapter defends a substantive thesis about the topic it addresses and the handbook as a whole thereby provides a strong foundation for future research in this important and growing field of inquiry.
