Throughout recorded human history, there exists a circular nature to the rise and fall of the great or powerful civilisations. This can be thought of as a series of stages, listed below, that describes the path each major power takes in their rise to supremacy and eventual ruin.
From bondage to spiritual faith
From spiritual faith to great courage
From great courage to strength
From strength to liberty
From liberty to abundance
From abundance to leisure
For leisure to selfishness
From selfishness to complacency
From complacency to apathy
From apathy to dependency
From dependency to weakness
From weakness to bondage
