convention between a superior and an inferior, but a convention between the body and each of its members. It is legitimate, because based on the social contract, and equitable, because common to all; useful, because it can have no other object than the general good, and stable, because guaranteed by the public force and the supreme power. So long as the subjects have to submit only to conventions of this sort, they obey no one but their own will; and to ask how far the respective rights of the Sovereign and the citizens extend, is to ask up to what point the latter can enter into undertakings with themselves, each with all, and all with each.
We can see from this that the sovereign power, absolute, sacred and inviolable as it is, does not and cannot exceed the limits of general conventions, and that every man may dispose at will of such goods and liberty as these conventions leave him; so that the Sovereign never has a right to lay more charges on one subject than on another, because, in that case, the question becomes particular, and ceases to be within its competency.
