These are the reflections which give rise to the difficulty about what is equitable. Now, in a way, they are all correct and not incompatible with one another; for that which is equitable, though it is better than that which is just (in one sense of the word), is yet itself just, and is not better than what is just in the sense of being something generically distinct from it. What is just, then, and what is equitable are generically the same, and both are good, though what is equitable is better.
But what obscures the matter is that though what is equitable is just, it is not identical with, but a correction of, that which is just according to law.
The reason of this is that every law is laid down in general terms, while there are matters about which it is impossible to speak correctly in general terms. Where, then, it is necessary to speak in general terms, but impossible to do so correctly, the legislator lays down that which holds good for the majority of cases, being quite aware that it does not hold good for all.
