During the nation-building process, the central authority had not only to contend with external defense, legislative and executive functions, economic management and relations between the communities or states that were being joined into the nation, but also with in many cases a much looser system of civil control and justice administration, wherein individuals, communities, states and nations had a vast patchwork of different laws or customs, and in many cases, regions were essentially lawless and under the control of whoever could gather the arms and organise the forces to gain and keep control of an area. Today most nations have brought this unruly situation under substantial control, and while there may be gaps or areas where this is not the case, it is clear that for a world-state, this need not be the first order of business; rather, the world-state could assume that for the most part nations will continue to maintain their ability to manage and police their internal affairs. This simplifies the process to a great degree.
Sri Aurobindo observes: “At the present day, not only are societies tolerably well-organised in this respect and equipped with the absolutely necessary agreements between country and country, but by an elaborate system of national, regional and municipal governments linked up by an increasingly rapid power of communication the State can regulate parts of the order of life with which the cruder governments of old were quite unable to deal with any full effect. In the World-State, it may be thought, each country may be left to its own free action in matters of its internal order and, indeed, of all its separate political, social and cultural life. But even here it is probable that the World-State would demand a greater centralisation and uniformity than we can now easily imagine.”
Improvements in the management of the internal relations of the citizens of a society will surely be possible as humanity develops more balanced, efficient and fair relations for all its members.
