Peter Coleman and Morton Deutsch are working on a book that will discuss 1) Psychological contributions to the prevention of war and violent, destructive conflicts; 2) The nature of a sustainable, harmonious peace; and 3) The psychological components of a sustainable, harmonious peace. This book is concerned with what psychological theory and research can contribute to the promotion of a harmonious, sustainable peace. Underlying this orientation is our belief that promoting the ideas and actions which can lead to a sustainable, harmonious peace not only contribute to the prevention of war but will also lead to more positive, constructive relations among people and nations, but also to a more sustainable planet. Book contributors will include: M. Deutsch, P.T. Coleman, D. Johnson, J. Jost, D. Druckman, A. Gratch, E. Lindner, B. Reardon, R. Vallacher, E. Staub, D. Christie, D. Wagner, J.P. Lederach, and L. Taylor.
