Why do we need a common theme? A common theme is a good way to represent the interdisciplinary aspects of UWGB. The theme may be one phrase; in this case it’s Global Citizenship in an Evolving World. But that one phrase means different things to different people. Each one of us will interpret it differently. By sharing those interpretations, not only are we learning to think in different ways, but we are also learning to listen to each other openly.
