If, when the people, being furnished with adequate information, held its deliberations, the citizens had no communication one with another, the grand total of the small differences would always give the general will, and the decision would always be good. But when factions arise, and partial associations are formed at the expense of the great association, the will of each of these associations becomes general in relation to its members, while it remains particular in relation to the State: it may then be said that there are no longer as many votes as there are men, but only as many as there are associations. The differences become less numerous and give a less general result. Lastly, when one of these associations is so great as to prevail over all the rest, the result is no longer a sum of small differences, but a single difference; in this case there is no longer a general will, and the opinion which prevails is purely particular. It is therefore essential, if the general will is to be able to express itself, that there should be no partial society within the State, and that each citizen should think only his own thoughts:[2] which was indeed the sublime and unique system established by the great Lycurgus. But if there are partial societies, it is best to have as many as possible and to prevent them from being unequal, as was done by Solon, Numa and Servius. These precautions are the only ones that can guarantee that the general will shall be always enlightened, and that the people shall in no way deceive itself. [1] "Every interest," says the Marquis d'Argenson, "has different principles. The agreement of two particular interests is formed by opposition to a third." He might have added that the agreement of all interests is formed by opposition to that of each. If there were no different interests, the common interest would be barely felt, as it would encounter no obstacle; all would go on of its own accord, and politics would cease to be an art. [2] "In fact," says Macchiavelli, "there are some divisions that are harmful to a Republic and some that are advantageous. Those which stir up sects and parties are harmful; those attended by neither are advantageous. Since, then, the founder of a Republic cannot help enmities arising, he ought at least to prevent them from growing into sects" (_History of Florence,_ Book vii). Rousseau quotes the Italian. CHAPTER IV THE LIMITS OF THE SOVEREIGN POWER If the State is a moral person whose life is in the union of its members, and if the most important of its cares is the care for its own preservation, it must have a universal and compelling force, in order to move and dispose each part as may be most advantageous to the whole. As nature gives each man absolute power over all his members, the social compact gives the body politic absolute power over all its members also; and it is this power which, under the direction of the general will, bears, as I have said, the name of Sovereignty.
