In this chapter, the author looks at definitions of conflict and the often negative associations people carry about it. She points out the need for mediators to reflect on their own personal reaction to conflict, and how this may impact both negatively and positively on their work as a mediator. She introduces the reader to several definitions and theories of conflict. These range from the very negative to the positive, where the conflict is seen as a necessary requirement for creativity and development. The author suggests that conflict is always psychological and emotional, and as such is not about facts but about personal perceptions.
