How we define and (so) divide space and accord that space salience amid changing contexts is critical to theory, practice and management and the models we subsequently derive:
... The dichotomy does not cut, it defines, it surrounds the closure of a limit, it delineates a boundary. Within the space thus enclosed like meets like. Or rather, conversely, the specific convergance [convenance] or identity, the assembly of the analogous, delimits zones in the disorder which are distinguished from each other. The earth is separated from the waters, air divides from fire. ... p.28.
