On the frontlines—in humanitarian crises, in wars overseas, and around some kitchen tables here at home—I’d seen that peace is more than the absence of war, and that a good life entails more than the absence of suffering. A good peace, a solid peace, a peace in which communities can flourish, can only be built when we ask ourselves and each other to be more than just good, and better than just strong. And a good life, a meaningful life, a life in which we can enjoy the world and live with purpose, can only be built if we do more than live for ourselves.
