At once, in place of the individual personality of each contracting party, this act of association creates a moral and collective body, composed of as many members as the assembly contains votes, and receiving from this act its unity, its common identity, its life and its will. This public person, so formed by the union of all other persons, formerly took the name of _city_,[1] and now takes that of _Republic_ or _body politic_; it is called by its members _State_ when passive, _Sovereign_ when active, and _Power_ when compared with others like itself. Those who are associated in it take collectively the name of _people_, and severally are called _citizens_, as sharing in the sovereign power, and _subjects_, as being under the laws of the State. But these terms are often confused and taken one for another: it is enough to know how to distinguish them when they are being used with precision. [1] The real meaning of this word has been almost wholly lost in modern times; most people mistake a town for a city, and a townsman for a citizen. They do not know that houses make a town, but citizens a city. The same mistake long ago cost the Carthaginians dear. I have never read of the title of citizens being given to the subjects of any prince, not even the ancient Macedonians or the English of to-day, though they are nearer liberty than any one else. The French alone everywhere familiarly adopt the name of citizens, because, as can be seen from their dictionaries, they have no idea of its meaning; otherwise they would be guilty in usurping it, of the crime of _lèse-majesté_: among them, the name expresses a virtue, and not a right. When Bodin spoke of our citizens and townsmen, he fell into a bad blunder in taking the one class for the other. M. d'Alembert has avoided the error, and, in his article on Geneva, has clearly distinguished the four orders of men (or even five, counting mere foreigners) who dwell in our town, of which two only compose the Republic. No other French writer, to my knowledge, has understood the real meaning of the word citizen. CHAPTER VII THE SOVEREIGN This formula shows us that the act of association comprises a mutual undertaking between the public and the individuals, and that each individual, in making a contract, as we may say, with himself, is bound in a double capacity; as a member of the Sovereign he is bound to the individuals, and as a member of the State to the Sovereign. But the maxim of civil right, that no one is bound by undertakings made to himself, does not apply in this case; for there is a great difference between incurring an obligation to yourself and incurring one to a whole of which you form a part.
