Rule–Referent Principle
Canonical definition
The Rule–Referent Principle is the result that a rule is legitimate where the Content-Belief it rests on, that the conduct the rule reaches causes a Harm or raises the rate at which one occurs, has a live Referent in the conduct the rule reaches; where that Referent, or the rate in which it consists, is made known with the rule to the Individuals it binds; and where the rule is reviewed as that rate moves. A domain whose Referent has no joints, as human variation has none under the Diversity Referent, admits rules against carving and none that carve, and a domain in which no Referent is constitutively available, the aesthetic regime, admits no rule except where conduct in it reaches a live Referent elsewhere. The Principle follows from the Provenance Rule and its positive limb, under which a rule that names its Referent is a command whose provenance can be traced; from the Cost-Provenance Test, under which a rule whose Belief no live Referent governs draws the Cost of its maintenance from the Individuals it governs, as sanction; from the Punitive Inversion Principle, under which such a sanction raises every coupling it reaches; and from Referent Foreclosure, under which a rule whose Referent is a rate answers to the rate and not to the instance, and cannot show its own necessity from its own record. Three consequences attach. Being caught presupposes a rule, so a justice system that does not punish needs its rules more than a punishing one does. The duty to make the Referent known falls on the rule-maker as a condition of the rule's legitimacy and is not an exemption for the one who breaks the rule. A rule whose Referent has gone is repealed, a rule that is holding its Referent's rate down is kept, and the two are told apart by the rate across many occasions rather than by the rule's own record.
Explanation
A rule is only as sound as the reason behind it, and the reason is something in the world the rule protects: a child stepping out near a school, scarce parking that has to be shared, a neighbour's sleep. When the rule says what that is, people can check it, and many keep the rule because they understand it rather than because they fear the fine. When a rule cannot say what it protects, nothing holds it in place except punishment, and punishment makes things worse. Some reasons are about rates rather than single events. Most drink-driven trips end safely, but the crash rate is real, so the rule is sound even on a night when nothing happens. Rules should change when what they protect changes, and go when it has gone, but carefully, because a rule that works hides the danger it is holding back. Where the world has no natural dividing lines, as with human variation, the only sound rules are those that stop people being sorted and ranked, and where there is nothing to protect at all, as with taste in music or dress, there should be no rule. A person is still bound by a rule they did not understand. The duty to explain it belongs to whoever made it.
