Beginning with the achievements of Mahatma Gandhi, and following the legacy of nonviolence through the struggles against Nazism in Europe, racism in America, oppression in China and Latin America, and ethnic conflicts in Africa and Bosnia, Michael Nagler unveils a hidden history. Nonviolence, he proposes, has proven its power against arms and social injustice wherever it has been correctly understood and applied.

Nagler's approach is not only historical but also spiritual, drawing on the experience of Gandhi and other activists and teachers. Individual chapters include A Way Out of Hell, The Sweet Sound of Order, and A Clear Picture of Peace. The last chapter includes a five-point blueprint for change and "study circle" guide. The foreword by Arun Gandhi, the grandson of Mahatma Gandhi, is new to this edition.
