not apply to hunter-gatherer societies. It does not apply either to the Greek and Roman world, where there was a wide variation in childrearing practices. It is notable that the arrival of the Ambivalent mode of child-rearing preceded the start of the Renaissance (mid 14th century) by only one or two generations, and the arrival of the Socializing mode coincided with the Age of Enlightenment, which began in the late 18th century. Earlier forms of childrearing coexist with later modes, even in the most advanced countries. An example of this are reports of selective abortion (and sometimes exposure of baby girls) especially in China, Korea, Taiwan, Singapore, Malaysia, India, Pakistan, New Guinea, and many other developing countries in Asia and North Africa, regions in which millions of women are "missing". The conflict of new and old psychoclasses is also highlighted in psychohistorians' thought. This is reflected in political contrasts – for instance, in the clash between Blue State and Red State voters in the contemporary United States – and in civil wars. Another key psychohistorical concept is that of group fantasy, which deMause regards as a mediating force between a psychoclass's collective childhood experiences (and the psychic conflicts emerging therefrom), and the psychoclass's behavior in politics, religion and other aspects of social life. A psychoclass for postmodern times According to the psychogenic theory, since Neanderthal man most tribes and families practiced infanticide, child mutilation, incest and beating of their children throughout prehistory and history. Presently the Western socializing mode of childrearing is considered much less abusive in the field, though this mode is not yet entirely free of abuse. In the opening paragraph of his seminal essay "The Evolution of Childhood" (first article in The History of Childhood), DeMause states: The history of childhood is a nightmare from which we have only recently begun to awaken. The further back in history one goes, the lower the level of childcare, and the more likely children are to be killed, abandoned, beaten, terrorized and sexually abused. There is notwithstanding an optimistic trait in the field. In a world of "helping mode" parents, deMause believes, violence of any other sort will disappear as well, along with magical thinking, mental disorders, wars and other inhumanities of man against man. Although, the criticism has been made that this itself is a form of magical thinking. Criticisms There are no departments dedicated to "psychohistory" in any
