Reality studies: Reflections on the possible and actual

What can science and science fiction tell us about the intertwining of the actual and the possible, the relations of imagination and reality? What are some of the ways those relationships can work? Should we be foregrounding possibilities that come primarily from our imaginations or the realities that push our imaginations? Contrary to common assumptions, this essay argues that imagination itself tends to be quite limited, but in some situations can become dangerously ungrounded. In contrast, the challenges of reality are more likely to push us to imagine previously inconceivable and transformative possibilities.
