Since men cannot create new forces, but merely combine and control those which already exist, the only way in which they can preserve themselves is by uniting their separate powers in a combination strong enough to overcome any resistance, uniting them so that their powers are directed by a single motive and act in concert.
Jean-Jacques RousseauThe problem is to find a form of association which will defend and protect with the whole common force the person and goods of each associate, and in which each, while uniting himself with all, may still obey himself alone, and remain as free as before.
Jean-Jacques Rousseau
