Psychohistory, like psychoanalysis, is a science in which the researcher's feelings are as much or even more a part of his research equipment than his eyes or his hands. Weighing of complex motives can only be accomplished by identification with human actors, the usual suppression of all feeling preached and followed by most "science" simply cripples a psychohistorian as badly as it would cripple a biologist to be forbidden the use of a microscope. The emotional development of a psychohistorian is therefore as much a topic for discussion as his or her intellectual development.

The source of most human violence and suffering has been a hidden children's holocaust throughout history, whereby billions of innocent human beings have been routinely murdered, bound, starved, raped, mutilated, battered, and tortured by their parents and other caregivers, so that they grow up as emotionally crippled adults and become vengeful time bombs who periodically restage their early traumas in sacrificial rites called wars.

Sociologists and historians have avoided looking for the family sources of wars and social violence. Whenever a group produces murderers, the early parental relationship must have been abusive and neglectful. Yet this elementary truth has not even begun to be considered in historical research; just stating that poor mothering lies behind wars seems blasphemous.

Historians are presumed to be unable to "do psychology," which is "mystical" anyway, so they are forced to accept the most "rational" explanations... "and it is on these that history is built.

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.

There is, for instance, only one page at the beginning of Runciman's three-volume History of the Crusades describing how the participants decided to begin four hundred years of wars, and then several thousand pages devoted to the routes, battles and other events which make up the "history" of the Crusades.
