And so, of that which is just, that part which is conventional and prescribed with a view to a particular end 125 varies as measures vary; for the measures of wine and of corn are not everywhere the same, but larger where the dealers buy, and smaller where they sell. 126 So I say that which is just not by nature but merely by human ordinance is not the same everywhere, any more than constitutions are everywhere the same, though there is but one constitution that is naturally the best everywhere.

The terms “just” and “lawful” in each of their several senses stand for universal notions which embrace a number of particulars; i.e. the acts are many, but the notion is one, for it is applied to all alike.
