" After having striven long in vain to solve the insoluble problem — the problem of constructing a government “which will constrain the individual to obedience without itself ceasing to be the servant of society,” men at last attempt to free themselves from every form of government and to satisfy their need for organization by a free contract between individuals and groups pursuing the same aim. The independence of each small territorial unit becomes a pressing need; mutual agreement replaces law, and everywhere regulates individual interests in view of a common object. "
