Psychoanalysts, too, tend to withhold their empathy in reaction to the destruction fantasies which were realized under the Nazi regime and to the "psychotic cosmos" established in the concentration camps. This explains why the effects of extreme traumatization, which the inmates of German death camps suffered and which have become known as "survivor syndrome," have been only gradually recognized and studied. Those who escaped, having been the victims of traumas which crush any psychic structure, pass their disturbances on to their children by way of overtaxing legacies. Thus a cumulative trauma is inflicted on the second generation.
