For me, the legacy of Marshall’s lifelong work doesn’t lie in how he revolutionized the role of the mediator, valuable as that was. It lies in the new value system he lived by, which in truth is quite ancient. Ahimsa has to be revived in every generation, because human nature is torn between peace and violence. Marshall Rosenberg gave proof that entering this state of expanded awareness was real and, when it came to settling disputes, very practical.
