What makes us human is our special motivation to share with others how we feel, what we believe, and what we want to happen in the future. We want to share with others what is real about the world. Shared reality is crucial to what we believe--sharing is believing. It is central to our sense of self, what we strive for and how we strive. It is basic to how we get along with others. It brings us together in fellowship (...) and companionship, but it also tears us apart by creating in-group "bubbles" that conflict with one another. Our shared realities are the best of us, and the worst of us. (shrink)
