I get it as if that is what settlements are made of... An always give and take between the dweller and the world (this last taken as both the nature and the neighbors even if settled far apart). At Rainer's oikology indeed those lines fluctuating between imagination and reality could be taken as root condition for the making of civilization regardless if nomadic or sedentary... What do we domesticate with the use of language? A common field of agreement between dwellers and the world, I guess...
