We must learn to hold the tension between the reality of the moment and the possibility that something better might emerge. The insight at the heart of nonviolence is that  we live in a tragic gap – a gap between the way things are and the way we know they might be. It is a gap that never has been and never will be closed. If we want to live nonviolent lives, we must learn to stand in the tragic gap, faithfully holding the tension between reality and possibility in hopes of being opened to a third way.
