From Huckleberry Finn to Harry Potter, from Internet filters to the v-chip, censorship exercised on behalf of children and adolescents is often based on the assumption that they must be protected from “indecent” information that might harm their development—whether in art, in literature, or on a Web site. But where does this assumption come from, and is it true? In Not in Front of the Children, Marjorie Heins explores the fascinating history of “indecency” laws and other restrictions aimed at protecting youth. From Plato’s argument for rigid censorship, through Victorian laws aimed at repressing libidinous thoughts, to contemporary battles over sex education in public schools and violence in the media, Heins guides us through what became, and remains, an ideological minefield. With fascinating examples drawn from around the globe, she suggests that the “harm to minors” argument rests on shaky foundations.
