We may think and talk about civilization as one pattern or level of culture, one stage through which human life flows and ebbs. In that sense we may regard it abstractly and historically, as we regard the most recent ice age or the long and painful record of large-scale chattel slavery.From quite another viewpoint we may think of civilization as a technologically advanced way of life developed by various peoples through ages of unrecorded experiment and experience, and followed by millions during the period of written history. It is also the way of life that the West has been trying to impose upon the entire human family since European empires launched their crusade to westernize, modernize and civilize the planet Earth.A third approach would regard civilization as an evolving life style, conceived before the earliest days of recorded human history and matured through the series of experiments marking the development of civilization as we have known it during the five centuries from 1450 to 1975.Thinking in terms of this age-old experience, with six or more thousand years of social history as a background, it is possible to give a fairly exact meaning to the word "civilization" as it has been lived and is being lived by the present-day West. It is also possible to understand the history of previous civilizations in cycle after cycle of their rise, their development, decline and extinction. At the same time it will enable the reader to recognize the relationship (and difference) between the words "culture" and "civilization".Human culture is the sum total of ideas, relationships, artifacts, institutions, purposes and ideals currently functioning in any community. Three elements are present in each human society: man, nature and the social structure. Human culture at any point in its history is the social structure: the aggregate of existing culture traits, the products of man's ingenuity, inventiveness and experimentation, set in their natural environment.Civilization is a level of culture built upon foundations laid down through long periods of pre-civilized living. These foundations consist of artifacts, implements, customs, habit patterns and institutions produced and developed in numerous scattered localities by groups of food-gatherers, migrating herdsmen, cultivators, hand craftsmen and traders and eventually in urban communities built around centers of wealth and power: the cities which are the nuclei of every civilization...
