Gay Science: The Ethics of Sexual Orientation Research is a 1997 book by the philosopher Timothy F. Murphy about scientific research on sexual orientation. The book received both positive reviews and more mixed assessments. Reviewers credited Murphy with providing a useful discussion of the ethical implications of sexual orientation research, including the work of scientists such as the neuroscientist Simon LeVay and the geneticist Dean Hamer, and with convincingly criticizing the philosopher John Finnis. However, his style of writing was criticized.
