Air "vs" Earth & Open "vs" Closed space

"The space of nomad thought is qualitatively different from State space. Air against earth. State space is "striated," or gridded. Movement in it is confined as by gravity to a horizontal plane, and limited by the order of that plane to preset paths between fixed and identifiable points. Nommad space is "smooth,' or open-ended. One can rise up at any point and move to any other. Its mode of distribution is the nomos: araying oneself in an open space (hold the street), as opposed to the logos of entrenching oneself in a closed space (hold the fort).
