The emotional plague is a scientific term that has two components, a somatic one, emotional destructiveness, and a psychic one, evil. It can appear on all levels of social organization from individuals to groups including political parties. People resist recognizing the existence and destructiveness of the plague partly because the disease is present in latent form and can appear in anyone under the right circumstances. Moreover, both components must first be recognized in oneself before one can have a true understanding of the plague’s destructive operation in others. A further obstacle is that, until recently, a functional understanding of human emotional life in determining social behavior, both healthy and sick, has not existed. This knowledge is made available to the public in the new science of social orgonomy.
