Limitation is essential to authority. A government is legitimate only if it is effectively limited.
Lord ActonWhenever a single definite object is made the supreme end of the State, be it the advantage of a class, the safety of the power of the country, the greatest happiness of the greatest number, or the support of any speculative idea, the State becomes for the time inevitably absolute. Liberty alone demands for its realization the limitation of the public authority, for liberty is the only object which benefits all alike, and provokes no sincere opposition.
Lord Acton
