The answer, therefore, to the critics who hold that, in securing civil liberty Rousseau has sacrificed the individual may be put after this fashion. Liberty is not a merely negative conception; it does not consist solely in the absence of restraint. The purest individualist, Herbert Spencer for example, would grant that a certain amount of State interference is necessary to secure liberty; but as soon as this idea of securing liberty is admitted in the smallest degree, the whole idea has undergone profound modification. It can no longer be claimed that every interference on the part of the State lessens the liberty of the individual; the “liberty-fund” theory is as untenable as that of the “wages-fund”: the members of a State may be more free when all are restrained from doing one another mutual damage than when anyone is left “free” to enslave another or be himself enslaved. This principle once admitted, the precise amount of State interference that is necessary to secure freedom will be always a matter for particular discussion; every case must be decided on its own merits, and, in right, the Sovereign will be omnipotent, or subject only to the law of reason.
