"...Cities may be rebuilt, and a People reduced to Poverty, may acquire fresh Property: But a Constitution of Government once changed from Freedom, can never be restored. Liberty once lost is lost forever. When the People once surrendered their share in the Legislature, and their Right of defending the Limitations upon the Government, and of resisting every Encroachment upon them, they can never regain it."
— John Adams
