Indeed, my conclusion from a lifetime of psychohistorical study of childhood and society is that the history of humanity is founded upon the abuse of children. Just as family therapists today find that child abuse often functions to hold families together as a way of solving their emotional problems, so, too, the routine assault of children has been society's most effective way of maintaining its collective emotional homeostasis. Most historical families once practiced infanticide, erotic beating and incest. Most states sacrificed and mutilated their children to relieve the guilt of adults. Even today, we continue to arrange the daily killing, maiming, molestation and starvation of children through our social, military and economic activities. I would like to summarize here some of the evidence I have found as to why child abuse has been humanity's most powerful and most successful ritual, why it has been the cause of war and social violence, and why the eradication of child abuse and neglect is the most important social task we face today.
It's quite a disturbing article so I hope Dr. deMause doesn't mind if I summarize the historical development here, with help from this guy.
From Prehistory to the spread of Christianity deMause theorizes we have the Infanticidal phase.
From, say AD 300 to 1300 there is the Abandoning phase;
C. 1300 to c. 1700, the Ambivalent phase;
C. 1700 to c. 1850, the Intrusive phase;
1850-1950, the Socializing phase;
1950-the present, the Helping phase.
The dates apply in European history only.
I'm the one calling them phases because I'm a weeny. DeMause's term is "psychoclasses." The good thing about that term is that it doesn't imply that the the timeline is absolute. All later phases are infected with remnants of all earlier phases, however large or small.
Indeed, I'd have to say that most parents, especially if they fetishize ancient religious texts, are mish-mashes of most of them, but having not studied more than this few that I've already quoted (and linked), I won't presume to speculate further.
