The crisis is a period in which a diseased social, economic, and political body or system cannot live on as before and is obliged, on pain of death, to undergo transformations that will give it a new lease on life. Therefore, this period of crisis is a historical moment of danger and suspense during which the crucial decisions and transformations are made, which will determine the future development of the system if any and its new social, economic, and political basis.

- André Gunder Frank
