At the outset we must realize that in any complex society there are wide ranges of ideology, from the body of ideas held by small uninfluential sects to the purposes, ideas, policy declarations and actions of governing oligarchies. We do not wish to defend or attack the ideas, but to summarize them and understand them in a way that will give a group picture of the purposes, ideas, policies and day-to-day activities of the civilizations in question. For convenience in our discussion we will take up, first, civilized societies as collectives, and then the operation of civilized ideology as expressed in the lives of individuals.

Presumably the most immediate purpose of all civilized peoples has been survival, getting on as a collective or group from day to day, through summer and winter, under normal conditions, and/or in periods of stress and emergency. If the group cannot survive it loses its identity, breaking up into the self-determining parts of which it is composed.

Survival means continued existence as a group—in the face of disruption from within or attack and invasion from without. The group which survives continues to exist and to act as a group that maintains the common defense and promotes the general welfare.

Each social group competing for survival has a sense of its own identity and a belief in its capacity to survive. This ideology is strengthened by the belief that the group has special qualities and is protected by powerful entities that will guarantee its success in the survival struggle. The group considers itself better qualified to survive than neighbor groups. Such ideas, carried to their logical conclusion, make the group in question superior to its neighbors in survival qualities and a people chosen by its gods.

A superior people, chosen by its gods, is in a class by itself. Other people, by comparison, are inferior. It is the destiny of the superior people to take the lands of their inferior neighbors, and, whenever opportunity offers, to defeat the neighbors in battle, capture them and force them to do the bidding of the captors.

Cults of ideological superiority are widespread. Put into successful practice by a victorious tribe, nation or empire, they develop into cults of superiority which assert: "We, the victors, are stronger, better people than our weaker neighbors." As one victory follows another the belief in superiority grows. People in an expanding empire or burgeoning civilization are obviously better survivors than their less successful competitors.

Competitive survival struggle modifies the cultures of both victors and vanquished. The dispersal and adoption of culture traits, supplemented by negotiation and accommodation, broaden the geographical area of the victors, increasing the population and adding to the material resources, the wealth and income of the enlarged group. It may also involve the corresponding decrease of the geographical area, population, wealth and income of the vanquished.

In order to protect itself, preserve itself, to enlarge itself and, where possible, to improve itself, each competing groups aims to set up standards of ideas and conduct to which all living members of the group are presumed to agree and to which they must adhere. When new members enter the group, by birth or adoption, they are duly indoctrinated with the group ideology. Early in their history the individuals and sub-groups composing every civilization adopted such standards and promulgated them by the decree of a leader or by the common consent of associated groups, as the outcome of negotiation, discussion, give and take. During the history of every civilization such agreements were reached and recorded in compacts, treaties, laws, constitutions, specifying the nature and limits of the collective cultural uniformity at which the community aimed.

The struggle for collective uniformity was long and often bitter. Individuals and factions resented and resisted the imposition of group authority. Internal conflict led to civil wars in the course of which the group was divided or the solidarity of the group was reaffirmed despite hardships imposed on disagreeing, divergent minorities.

Closely paralleling the group need for survival and uniformity (solidarity) was the need for group expansion, or extension. In the competitive struggle for survival which played such an important role in the life of pre-civilized communities, strategic geographic location was often decisive. Soil fertility, mineral deposits, timber reserves, access to waterways, location on trade routes all played a part in community survival, stability and growth.
