By the community of race we may then mean a belief in a common origin, fictitious or legendary. Every nationality, as a matter of fact, has legendary tales of its non-historic origin which make the people to forget the diversity of their origins.
Whenever bodies of people believe that they belong to one race, they become a group of common consciousness and interests. One of the subtle ways of satisfying this group consciousness is to judge one’s own group by its best specimens and others by their worst. This group pride is a propelling force to the development of nationalism.
