Virtue needs to be taught. And authority is useful in teaching virtue. There is, perhaps, no more important duty for the family than moral education. While church leaders have no particular expertise to lecture about the best organization of the economy, they are well-equipped to offer a moral road map. Community institutions of various sorts also should play an important role.
Government simply lacks the tools to create a virtuous person.
Today, figures like Judge Robert Bork forthrightly call for censorship. Such restrictions might promote a habit of doing right, thereby aiding the process of moral education. Maybe, but not certainly. After all, while such laws historically have driven vice underground, it is not clear that they have measurably reduced the incidence of vice. Moreover, virtue cannot be exercised without free choice.
