In 1947, a man named Dr. Carle Zimmerman wrote a book called Family and Civilization. He reviewed the decline of multiple civilizations and empires, and found eight patterns of domestic behavior that signaled the decline of a civilization:
1) Marriage loses its sacredness; is frequently broken by divorce.
2) Traditional meaning of the marriage ceremony is lost.
3) Feminist movements abound.
4) Increased public disrespect for parents and authority in general.
5) Acceleration of juvenile delinquency, promiscuity, and rebellion.
6) Refusal of people with traditional marriages to accept family responsibilities.
7) Growing desire for and acceptance of adultery.
Increasing interest in and spread of sexual perversions and sex-related crimes.
Sound like any civilization you know?
