Fifty years ago, in 1958, Galtung for the first time was in a mediation situation. The conflict was between black and white over desegregation of the schools in Charlottesville, Virginia, USA. Since then there have been many and one hundred of them are reported in this book; most of them macro conflicts, some personal and social. The reader can read the densely written book in many ways. Scan the Table of Contents for a conflict of special interest. Read the Diagnosis sections for analysis of current affairs. Read the Prognosis sections for forecasts, future studies. Read the Therapy sections for remedies, beyond critical commentary, constructive, concrete and creative, 3 Cs. Read the whole book as a text in peace studies, much beyond conventional security and international studies, and ask yourself, what can I do for peace, including improving the many proposals? Johan Galtung, 77, lives in Spain, France, Japan and the USA and is mainly engaged in mediation and research. He founded TRANSCEND: A Network for Peace and Development in 1993, and was the first rector of the Transcend Peace University 2003-2007. This book is the first publication from Transcend University Press.
