We live in a networked world. War is networked: the power of terrorists and the militaries that would defeat them depend on small, mobile groups of warriors connected to one another and to intelligence, communications, and support networks. Diplomacy is networked: managing international crises -- from SARS to climate change -- requires mobilizing international networks of public and private actors. Business is networked: every CEO advice manual published in the past decade has focused on the shift from the vertical world of hierarchy to the horizontal world of networks. Media are networked: online blogs and other forms of participatory media depend on contributions from readers to create a vast, networked conversation. Society is networked: the world of MySpace is creating a global world of "OurSpace," linking hundreds of millions of individuals across continents. Even religion is networked: as the pastor Rick Warren has argued, "The only thing big enough to solve the problems of spiritual emptiness, selfish leadership, poverty, disease, and ignorance is the network of millions of churches all around the world."
In this world, the measure of power is connectedness. Almost 30 years ago, the psychologist Carol Gilligan wrote about differences between the genders in their modes of thinking. She observed that men tend to see the world as made up of hierarchies of power and seek to get to the top, whereas women tend to see the world as containing webs of relationships and seek to move to the center. Gilligan's observations may be a function of nurture rather than nature; regardless, the two lenses she identified capture the differences between the twentieth-century and the twenty-first-century worlds.
The twentieth-century world was, at least in terms of geopolitics, a billiard-ball world, described by the political scientist Arnold Wolfers as a system of self-contained states colliding with one another. The results of these collisions were determined by military and economic power. This world still exists today: Russia invades Georgia, Iran seeks nuclear weapons, the United States strengthens its ties with India
