Sociality has always been significant. Family relationships have always been of extreme importance to all human cultures. The family is the primary agent of the enculturation process. Its minor paradigms determine who may marry whom, how many one can marry, whose clan they should live with, how many children they should have, male or female lineages, inheritance, how to raise a child, and the proper roles of each member in relation to the other members. Since the family is the smallest group within the group, these practices are essential for the culture to function properly.
Social relationships are extremely important on the individual level.
These are the customs of non-familial relationships with friends and acquaintances. Organizations also pertain to the individual as it encompasses vocation, gathering with peers, and gathering together to advocate a particular meme. Morality is based on the human need to belong. Membership in any group requires one to first master the complex matrix of traditions which have evolved within that particular group. What is considered virtuous, normal, and abhorrent behavior has been impressed on the individual through the process of immersion into the group.
