Problem of existence
The basic "problems of existence" that face all human societies if they are to survive and develop are:
a. The economic problem of how to produce the things needed for human survival.
b. The political problem of how to ensure that society is orderly and stable. The problem here, therefore, is one of government and control over people's behaviour. In short, the need is the need to enforce rules of acceptable behaviour.
c. The family problem of how to ensure that children are born and looked after in a way that allows them to grow into functioning adult members of society.
d. The cultural problem of how to make people feel they have things in common with others. How, in short, to make people feel they belong to a common culture / society.
