"Viewed from the standpoint of social science, society is composed of individuals organized in occupational groups, each group fulfilling some function of the society. Taking this fact into account, psychology – the science of human nature and human consciousness – is able to make at least one general assertion as to the form a given society must take if it is to persist as a society. It must be possible for the individual as he works to see that his work is socially necessary; he must be able to see beyond his group to the society."
