Just finished Nonviolent Communication: a language of life by Marshall Rosenberg. Follow the link for a preview.
It’s a good book. Like everything, there are times when it’s not useful and times when it is, but this method (learn more at the Center for NonViolent Communication website) has a lot of potential for personal as well as community transformation. I especially appreciate the fact that it can be practiced solo–others don’t need to know the system for it to be effective.
