"The human soul has need of consented obedience and of liberty. Consented obedience is what one concedes to an authority because one judges it to be legitimate. It is not possible in relation to a political power established by conquest or coup d'etat nor to an economic power based upon money. Liberty is the power of choice within the latitude left between the direct constraint of natural forces and the authority accepted as legitimate. The latitude should be sufficiently wide for liberty to be more than a fiction, but it should include only what is innocent and should never be wide enough to permit certain kinds of crime."
