The human imagination gives rise to the most beautiful man-made structures and creations on Earth: architecture, literature, theatre, music, art, humanitarian initiatives, moon landings and space exploration, mythology, science, they all require a large dose of imagination. We all live surrounded by the results of the imagination of our peers, and the creations of our ancestors. Without imagination there is no compassion, no moral compass and no progress. But without imagination there is also no fear of death. There are no premeditated murders or terrorist attacks; these rely on the human ability to imagine, to call up images and test-drive possible scenarios in the human mind. Once we get out the magnifying glass, we discover that the imagination is a double-edged sword. All of us together, humanity as a collective, are creating very confused and mixed outcomes: world peace remains elusive, wars rage and children starve. Addictions and pollution proliferate. Medicine of the Imagination: Dwelling in Possibility examines these issues and suggests that if we are to transcend religious wars, homophobia and medical “cures” worse than the diseases we face then it that it is our moral duty to engage our imagination in service to other people.
