“Nomadism is born of wide expanses, ground too barren for the farmer to cultivate economically – savannah, steppe, desert and tundra, all of which will support an animal population providing that it moves. For the nomad, movement is morality. Without movement, his animals would die. Nomads never roam aimlessly from place to place, as one dictionary would have it. A nomadic migration is a guided tour of animals around a predictable sequence of pastures… For life in the black tents has not significantly changed since Abraham, the Bedouin sheikh, moved his flock on his ‘journeys from the south even unto Bethel, where his tent had been at the beginning.'” (Genesis 13:3)

– Bruce Chatwin, What Am I Doing Here? p.219 – 220 (1988)

‘Wide expanses’ are unstructured data.
More next week.
Maybe.
