As the above tribute to the life and work of Lonnie Valentine by Steve Angell and Colleen Wessel-McCoy offers an excellent overview of the many contributions that Lonnie Valentine has made over his lifetime, his gathering of these essays marks his culminative life-long contribution to the future of peacemaking from a Quaker perspective. ¿After the introductory section, essays in Part I by Doug Gwyn, Jennifer Buck, and Paul Anderson explore the origin and development of the Quaker Peace Testimony. Essays in Part II by Richard Miller, Mike Heller, Sherrema A. Oom-Dove, Cherice Bock, and Christine Ashley develop particular stories in the development of peacemaking issues among Friends over the years. Work accomplished and yet to be done is addressed meaningfully in this section. Part III includes essays on the theory and practice of peacemaking, and the contributions of Diana and John Lampen, Eric Ginsburg, Laura Rediehs, David Gross, Sue Williams, and Ron Mock further those concerns. Essays by Chuck Fager, Barbara Birch, Diane Randall, Gray Cox, Laura Rediehs, and Daniel Snyder in Part IV address the problems and promise of peacemaking in a number of meaningful ways; and in Part V, Daniel Hunter sketches reflections and prospects as we consider the future of peacemaking among friends, in addition to its present and past developments.
