By CIVILL LAWES, I understand the Lawes, that men are therefore bound to observe, because they are Members, not of this, or that Common-wealth in particular, but of a Common-wealth. For the knowledge of particular Lawes belongeth to them, that professe the study of the Lawes of their severall Countries; but the knowledge of Civill Law in generall, to any man. The antient Law of Rome was called their Civil Law, from the word Civitas, which signifies a Common-wealth; And those Countries, which having been under the Roman Empire, and governed by that Law, retaine still such part thereof as they think fit, call that part the Civill Law, to distinguish it from the rest of their own Civill Lawes. But that is not it I intend to speak of here; my designe being not to shew what is Law here, and there; but what is Law; as Plato, Aristotle, Cicero, and divers others have done, without taking upon them the profession of the study of the Law.
And first it manifest, that Law in generall, is not Counsell, but Command; nor a Command of any man to any man; but only of him, whose Command is addressed to one formerly obliged to obey him. And as for Civill Law, it addeth only the name of the person Commanding, which is Persona Civitatis, the Person of the Common-wealth.
Which considered, I define Civill Law in this Manner. “CIVILL LAW, Is to every Subject, those Rules, which the Common-wealth hath Commanded him, by Word, Writing, or other sufficient Sign of the Will, to make use of, for the Distinction of Right, and Wrong; that is to say, of what is contrary, and what is not contrary to the Rule.”
In which definition, there is nothing that is not at first sight evident. For every man seeth, that some Lawes are addressed to all the Subjects in generall; some to particular Provinces; some to particular Vocations; and some to particular Men; and are therefore Lawes, to every of those to whom the Command is directed; and to none else. As also, that Lawes are the Rules of Just, and Unjust; nothing being reputed Unjust, that is not contrary to some Law. Likewise, that none can make Lawes but the Common-wealth; because our Subjection is to the Common-wealth only: and that Commands, are to be signified by sufficient Signs; because a man knows not otherwise how to obey them. And therefore, whatsoever can from this definition by necessary consequence be deduced, ought to be acknowledged for truth. Now I deduce from it this that followeth.
