IF man were to live in a state of nature, unconnected with other individuals, there would be no occasion for any other laws, than the law of nature, and the law of God. Neither could any other law possibly exist; for a law always supposes some superior who is to make it; and in a state of nature we are all equal, without any other superior but him who is the author of our being. But man was formed for society; and, as is demonstrated by the writers on this subject[b], is neither capable of living alone, nor indeed has the courage to do it. However, as it is impossible for the whole race of mankind to be united in one great society, they must necessarily divide into many; and form separate states, commonwealths, and nations; entirely independent of each other, and yet liable to a mutual intercourse. Hence arises a third kind of law to regulate this mutual intercourse, called "the law of nations;" which, as none of these states will acknowlege a superiority in the other, cannot be dictated by either; but depends entirely upon the rules of natural law, or upon mutual compacts, treaties, leagues, and agreements between these several communities: in the construction also of which compacts we have no other rule to resort to, but the law of nature; being the only one to which both communities are equally subject: and therefore the civil law[c] very justly observes, that _quod naturalis ratio inter omnes homines constituit, vocatur jus gentium_. [Footnote b: Puffendorf, _l._ 7. _c._ 1. compared with Barbeyrac's commentary.] [Footnote c: _Ff._ 1. 1. 9.] THUS much I thought it necessary to premise concerning the law of nature, the revealed law, and the law of nations, before I proceeded to treat more fully of the principal subject of this section, municipal or civil law; that is, the rule by which particular districts, communities, or nations are governed; being thus defined by Justinian[d], "_jus civile est quod quisque sibi populus constituit_." I call it _municipal_ law, in compliance with common speech; for, tho' strictly that expression denotes the particular customs of one single _municipium_ or free town, yet it may with sufficient propriety be applied to any one state or nation, which is governed by the same laws and customs. [Footnote d: _Inst._ 1. 2. 1.] MUNICIPAL law, thus understood, is properly defined to be "a rule of civil conduct prescribed by the supreme power in a state, commanding what is right and prohibiting what is wrong." Let us endeavour to explain it's several properties, as they arise out of this definition.
