A great deal of human history has been a record of antagonism and conflict between groups. Indeed, the most terrible atrocities committed by humans have often not been the acts of criminals or madmen but of ordinary, loyal citizens acting in the presumed interests of their group against another group.
The immense advances in science and technology during the past few centuries have not diminished the intensity and frequency of intergroup hatreds and violence. In fact, the growth of military and political power has introduced a scale of massacre and destruction that makes the efforts of previous centuries to achieve peace seem modest by comparison.
Yet these are still exceptional events. It is only under particular circumstances that intergroup animosities erupt into open violence and killing. Underlying these periodic eruptions are patterns of intergroup dislike, resentment, and discrimination that are all too common. Prejudiced attitudes and beliefs whether national, tribal, racial, religious - pervade human social life. They are remarkable not in their existence, but in their sheer cruelty, the ease with which they can be aroused, and the tenacity with which they are held.
