Anarchy is what happens wherever order is not imposed by force. It is freedom: the process of continually reinventing ourselves and our relationships. Any freely occurring process or phenomenon—a rainforest, a circle of friends, your own body—is an anarchic harmony that persists through constant change. Top-down control, on the other hand, can only be maintained by constraint or coercion: the precarious discipline of the high-school detention room, the factory farm in which pesticides and herbicides defend sterile rows of genetically modified corn, the fragile hegemony of a superpower.
