Among the Kesh, being 'rich' means giving much away; status comes from what a person or household distributes, not what it keeps. Accumulation and hoarding count as a kind of poverty or illness, so the social incentive runs toward circulation rather than possession.
Stone Telling, born of a Kesh mother and a Condor father, goes to live among her father's people. She finds a militarized, strictly hierarchical society that worships a single god, One, and confines and silences women, and she eventually escapes home with her daughter. Her account shows the 'Sickness of Man' (domination, expansion, a single center of authority) re-emerging even after industrial civilization has collapsed, as a recurring social pattern rather than a vanished era.
The City of Mind is a self-sustaining network of computers that has outlived its makers and pursues its own ends. The Kesh draw on its stored knowledge through local Exchanges, but it does not organize or direct their lives. Advanced technology persists, but people deliberately choose how much of it to take up, keeping information available without letting it become the center of the society.
The book presents an imagined future people through the apparatus of ethnography: field notes, texts, glossary, grammar, recipes and maps. This lets the reader 'dig up' a culture that does not yet exist. Treating the future as a site to be excavated makes the reader's own present look strange and contingent, one possible way of living among others rather than the inevitable endpoint of progress.
