SUMMARY Part I of this book argues that we live in a dangerous world system, one that has sickened humanity. Part II argues that there is a way out, in re-imagining how things could be. Everyone has a role to play in the renewal of the social system, since our leaders have largely failed and many institutions are collapsing. Existential Threats are those problems that endanger the life and well-being of everyone like war and nuclear weapons, accelerating climate change, over-population, cultural violence, injustice, and the inequality of capitalism. As serious as these problems are, they are not permanent. Moral Prospects are the possibilities that represent the most significant social change like, ending war and militarism, predatory capitalism, humanly caused climate change, over-population, cultural violence, and moral corruption. The system can be changed for the better through an enlightened population. Although some Existential Threats may be pedestrian and local, others are global and apocalyptic, endangering all species. At the same time, the crisis created by world events, presents great opportunities for transformative change with revolutionary consequences.
