The average of the world's great civilizations before they decline

"The average of the world's great civilizations before they decline has been 200 years. These nations have progressed in this sequence: From bondage to spiritual faith; from spiritual faith to great courage; from courage to liberty; from liberty to abundance; from abundance to selfishness; from selfishness to complacency; from complacency to apathy; from apathy to dependency; from dependency back again to bondage."

- Alexander Tytler, Cycle of Democracy, 1770
