“Each of us too sees the world through our own “filter”—a filter made up of our assumptions, our motivations, and the categories we use to sort out and organize our experience. This filter determines how we see the world. When we come across something that doesn’t match our assumptions, motivations, and categories, our filter blocks it out. It’s not that we choose to reject it. Consciously, we don’t even perceive it. Or else we perceive it in a partial, distorted form. It seems that nonviolence has a particularly hard time passing through many people’s filters.”
