Five decades after World War II and in the aftermath of the Cold War, a new world is taking shape. Which path the world takes will depend on the extent to which people and their leaders develop the vision of a better world - and the strategies, the institutions, and the will to achieve it. This work suggests approaches to the governance of our increasingly interdependent human society. It makes recommendations to promote the security of people, manage economic interdependence, strenghten international law, and reform the United Nations and other institutions.
