Kathleen Lubey’s book What Pornography Knows: Sex and Social Protest Since the Eighteenth Century (Stanford UP, 2022) offers a new history of pornography based on forgotten bawdy fiction of the eighteenth century, its nineteenth-century republication, and its appearance in 1960s paperbacks. Through close textual study, Lubey shows how these texts were edited across time to become what we think pornography is—a genre focused primarily on sex. Originally, they were far more variable, joining speculative philosophy and feminist theory to sexual description.
