But as society, more especially when very numerous, is incapable of assembling itself, unless with great difficulty, as it cannot with tumult make known its intentions, it is obliged to choose citizens in whom it places a confidence, whom it makes the interpreter of its will, whom it constitutes the depositaries of the power requisite to carry it into execution. Such is the origin of all _government_, which to be legitimate can only be founded on the free consent of society. Those who are charged with the care of governing, call themselves sovereigns, chiefs, legislators: according to the form which society has been willing to give to its government: these sovereigns are styled monarchs, magistrates, representatives, &c. Government only borrows its power from society: being established for no other purpose than its welfare, it is evident society can revoke this power whenever its interest shall exact it; change the form of its government; extend or limit the power which it has confided to its chiefs, over whom, by the immutable laws of Nature, it always conserves a supreme authority: because these laws enjoin, that the part shall always remain subordinate to the whole. Thus sovereigns are the ministers of society, its interpreters, the depositaries of a greater or of a less portion of its power; but they are not its absolute masters, neither are they the proprietors of nations. By a _covenant_, either expressed or implied, they engage themselves to watch over the maintenance, to occupy themselves with the welfare of society; it is only upon these conditions society consents to obey them. The price of obedience is protection. There is or ought to be a reciprocity of interest between the governed and the governor: whenever this reciprocity is wanting, society is in that state of confusion of which we spoke in the fifth chapter: it is verging on destruction. No society upon earth was ever willing or competent to confer irrevocably upon its chiefs the power, the right, of doing it injury. Such a concession, such a compact, would be annulled, would be rendered void by Nature; because she wills that each society, the same as each individual of the human species shall tend to its own conservation; it has not therefore the capacity to consent to its permanent unhappiness. _Laws_, in order that they may be just, ought invariably to have for their end, the general interest of society; that is to say, to assure to the greater number of citizens those advantages for which man originally associated. These advantages are _liberty, property, security_. _Liberty_, to man, is the faculty of doing, for his own peculiar happiness, every thing which does not injure or diminish the happiness of his associates: in associating, each individual renounced the exercise of that portion of his natural liberty which would be able to prejudice or injure the liberty of his fellows. The exercise of that liberty which is injurious to society is called _licentiousness_.
