Sexual Deceit: The Ethics of Passing shows an excellent understanding and command of the scholarship on the issues. This is particularly notable because the approaches of what I will call traditional philosophy and of queer theory are very different, and it can seem to readers as if they are speaking different languages. The author not only handles the different approaches/traditions well, but also combines their insights, key concepts, and important arguments in developing an ethical theory the author calls “Gayness as Practical Identity,” or just “Gayness.” And this serves as an ethical theory that can be applied to many issues in addition to passing. I think that this theory, which I will call a theory of gay ethics is an important contribution to ethics and LGBT studies.
