" our extraordinary ability to use language and symbols enables us to communicate with others personally, abstractly, over time and place. Language provides the foundation for history, planning, and social control. However, with language come rumors, lies, propaganda, stereotypes, and coercive rules. Our remarkable creative genius leads to great literature, drama, music, science, and inventions like the computer and the Internet. Yet that same creativity can be perverted into inventing torture chambers and torture tactics, into paranoid ideologies and the Nazis’ efficient system of mass murder. Any one of our special attributes contains the possibility of its opposite negative, as in the dichotomies of love–hate; pride–arrogance; self-esteem–self-loathing.2 "
