THE PAPERS, ORIGINALLY PRESENTED AT TWO CONFERENCES ON VIOLENCE, PROVIDE GUIDELINES TO IDENTIFICATION, PREDICTION, TREATMENT, AND PREVENTION OF VIOLENT BEHAVIOR. AMONG THEM IS A WORK OUTLINING THE PSYCHOLOGICAL AND SOCIAL ROOTS OF VIOLENT BEHAVIOR AND DELINEATING FORMS AND CAUSES (BIOLOGIC, PSYCHOGENIC, AND SOCIOECONOMIC) OF VIOLENCE, AND HISTORICAL REVIEW OF METHODS FOR TESTING FOR CRIMINAL RESPONSIBILITY AND INSANITY AND OF TRADITIONAL CONCEPTS RELATING TO VIOLENCE AND RESPONSIBILITY, AND AN ARGUMENT PROPOSING THE MANDATORY TREATMENT OF VIOLENT PERSONS. PSYCHODYNAMIC ASPECTS OF VIOLENT BEHAVIOR INCLUDING POLITICAL, SOCIOLOGICAL, AND CULTURAL FACTORS ARE DEALT WITH IN A LATER PAPER, AND A LINK BETWEEN NEUROLOGICAL DISEASE AND VIOLENT BEHAVIOR (THE DYSCONTROL SYNDROME) IS DESCRIBED. A CRIMINOLOGIST APPROACHES THE PROBLEM FROM THE STANDPOINT OF FAMILY VIOLENCE AND CRIMINAL BEHAVIOR AND TIES THE SOCIOLOGICAL CONCEPTS TO INTRAPSYCHIC, MEDICAL, AND LEGAL FACTORS. A JUDGE REVIEWS COURT EXPERIENCES TO DESCRIBE THE SPECIAL VULNERABILITY OF MENTALLY DISABLED PERSONS, THE ELDERLY, AND THE INSTITUTIONALIZED TO VIOLENCE, AND A LAW PROFESSOR PRESENTS THE MEDICAL-LEGAL ASPECTS OF VIOLENCE TOWARD CHILDREN, FOCUSING ON ABUSE, NEGLECT, AND PARENTAL RESPONSIBILITY. THE CLOSING CHAPTER DEALS SPECIFICALLY WITH JUVENILE VIOLENCE AND DISCUSSES INDIVIDUAL RESPONSIBILITY AND SOCIAL-LEGAL CONTROLS. AN INDEX AND REFERENCES ARE PROVIDED.
