"Such levels of complexity exist for all the spheres, meaning that while each 'power' has a 'sphere' in which it is predominant, it is very difficult to make each sphere a closed system. [...] No sphere supplies all that it needs within itself, although some hearth societies, political regimes, and religious communities have attempted to be self-sufficient. Over time, encounter and exchange result. Each sphere must draw from what is around it; the permeability of each of each sphere means that each is always influenced by powers beyond itself. Economic life, to pursue the example above, is shaped not only by government and technology, but by the fact that people fall in love at the factory or office, which alters work habits, and sometimes leads to marriage and families, which further alters both earning and spending partners. Similarly, an erotic attraction is not only shaped by psychodynamics and familial history but by the economic (and cultural and political and religious) factors in the social context in which it takes place. If any one of these spheres begin to be dominated by an external power, distortion is inevitable.
