RELATIONSHIP OF MEN AND OF POLITICAL COMMUNITIES WITH THE WORLD COMMUNITY
130. Recent progress of science and technology has profoundly affected human beings and influenced men to work together and live as one family. There has been a great increase in the circulation of goods, of ideas and of persons from one country to another, so that relations have become closer between individuals, families and intermediate associations belonging to different political communities, and between the public authorities of those communities. At the same time the interdependence of national economies has grown deeper, one becoming progressively more closely related to the other, so that they become, as it were, integral parts of the one world economy. Likewise the social progress, order, security and peace of each country are necessarily connected with the social progress, order, security and peace of all other countries.
131. At the present day no political community is able to pursue its own interests and develop itself in isolation, because the degree of its prosperity and development is a reflection and a component part of the degree of prosperity and development of all the other political communities.
