Book 4, Chapter 7 — The Censorship

Rousseau begins by defining the censor's role in relation to the law. If law is the declaration of the general will, censorship is the declaration of public judgment — the form of law that the censor administers, applying it to particular cases as the prince applies civil law. The censor does not create opinion; he reveals and formalizes what the community already holds. His authority is entirely dependent on the accuracy of that revelation: the moment his declaration diverges from actual public opinion, it becomes void.

The chapter distinguishes what censorship can from what it cannot achieve. It can preserve morality by articulating and defending standards that already exist in the community's moral sense. It can occasionally fix opinion when it is still uncertain — by making a judgment before consensus has fully formed, the censor can tip the balance in a direction the community was already inclined to go. The example is apt: calling men who accept seconds in a duel cowards worked because the community was moving in that direction and needed only a clear statement to crystallize around.

But censorship cannot restore morality that has already been lost. Once the laws have failed — once the habits and customs that good laws create have deteriorated — no censor's declaration can substitute for the legislative force that created them. This is the limit that makes censorship a supplement to good government, not a substitute for it. In a well-governed republic, the censor's role is real but modest; in a corrupt one, it is useless. The chapter thus reinforces the book's consistent argument: institutions work when the society they serve is healthy, and fail when it is not.
