Book 5
4
The reason for this is that law is always a general statement, yet there are cases which it is not possible to cover in a general statement. In matters therefore where, while it is necessary to speak in general terms, it is not possible to do so correctly, the law takes into consideration the majority of cases, although it is not unaware of the error this involves. And this does not make it a wrong law; for the error is not in the law nor in the lawgiver, but in the nature of the case: the material of conduct is essentially irregular.
5
When therefore the law lays down a general rule, and thereafter a case arises which is an exception to the rule, it is then right, where the Iawgiver’s pronouncement because of its absoluteness is defective and erroneous, to rectify the defect by deciding as the lawgiver would himself decide if he were present on the occasion, and would have enacted if he had been cognizant of the case in question.
6
Hence, while the equitable is just, and is superior to one sort of justice, it is not superior to absolute justice, but only to the error due to its absolute statement. This is the essential nature of the equitable: it is a rectification of law where law is defective because of its generality. In fact this is the reason why things are not all determined by law: it is because there are some cases for which it is impossible to lay down a law, so that a special ordinance becomes necessary.
