Our body is a complex ecosystem comprised of specialized organs that behave according to their own advantage, with no greater concern for the whole. White blood cells have no opinion about disease, except that it is good to eat.
Human organization, like ecosystems, is an amalgamation of seperate entities with differing agendae. Governments, corporations, and other organizations, like brains, attempt to organize the free agents towards a conscious goal.
It would be interesting, for modern fiction, to see a world in which at the levels of body, human world, and natural ecosystem, are played out at each level, as something for the protagonist to deal with. Douglas Adams’ work comes to mind, or perhaps William Gibson’s _Neuromancer_, where the protagonist must work against other consciousnesses, some of which have set up his own body against him.
