is a basic characteristic that enables us to distinguish man, culture, or society as systems with some sort of continuity in time. Without sufficient coherence, no entity could be distinguished and analyzed. But, when going into a lower, more specific level of analysis of processes with prevailing homogeneous inner dynamics, we can also find other realms where coherence occurs. Beginning with the basic forces maintaining any culture, coherence secures the maintenance of existing rules, norms, standards, customs, symbols, social scripts, ceremonies, and rituals in the cultural systems. The traditions in cultural systems exist because of homogeneous agency of coherence. Without any coherence, no traditions or other forms of repeated behaviors could be distinguished in cultures. Also, the use of a shared language that is understandable to most of members of an ethnic group is related to the agency of coherence in terms of the shared use of a coherent symbolic system of signs. Homeostasis is very similar category to coherence, but it is much more related to the state of relative equilibrium in the inner environment of system. Homeostasis observed in human circulatory system is a typical example. In a similar vein, we may analyze the internal processes in towns and cities, which is an important issue within urban anthropology. Such processes may include the food supply for inhabitants, transport of people, or waste management. These processes of urban metabolism may or may not be in a relative equilibrium based on the operation of homogeneous inner dynamics with the character of homeostasis. Recurrence frames the group of processes that share the feature of “something that is repeating”. We may imagine various forms of recurrences, such as recurrences of very similar historical events in different historical periods. Historians sometimes say “history always repeats itself”, and comparisons of historical events from different historical periods also support this thesis (e.g., Turchin, 2003). Also, religious practices such as rituals are repeated because of the homogeneous agency of recurrence. In contrast, simplification means that some bigger system is decomposed into several lesser parts. Here, we can mention the dissolution of the Soviet Union. The unified republics of the former Union of Soviet Socialist Republics broke away between years 1989–1992, and became independent post-Soviet states. ( 98 )
