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.

What social and industrial research has not sufficiently realised as yet is that... minor irrationalities of the “average normal” person are cumulative in their effect. They may not cause “breakdown” in the individual but they do cause “breakdown” in the industry.
