And as we are no longer to talk of the “rights” of nations, so no longer must “independent” nations be the basis of union. In our present international law a sovereign nation is one that is independent of other nations—surely a complete legal fiction. And when stress is laid on independence in external relations as the nature of sovereignty, it is but a step to the German idea that independence of others can develop into authority over others. This tendency is avoided when we think of sovereignty: (1) as _looking in_, as authority over its own members, as the independence which is the result of the complete interdependence of those members; and when we at the same time (2) think of this independence as _looking out_ to other independences to form through a larger interdependence the larger sovereignty of a larger whole. Interdependence is the keynote of the relations of nations as it is the keynote of the relations of individuals within a nation. As no man can be entirely free except through his perfected relation to his group, so no nation can be truly independent until a genuine union has brought about interdependence. As we no longer think that every individual has a final purpose of his own independent of any community, so we no longer think that each nation has a “destiny” independent of the “destiny” of other nations. The error of our old political philosophy was that the state always looks in: it has obligations to its members, it has none to other states; it merely enters into agreements with them for mutual benefit thereby obtained. International law of the future must be based not on nations as “sovereigns” dealing with one another, but on nations as members of a society dealing with one another. The difference in these conceptions is enormous. We are told that cessions of sovereignty must be the basis of an international government. We cannot have a lasting international union until we entirely reform such notions of sovereignty: that the power of the larger unit is produced mechanically by taking away bits of power from all the separate units. Sovereignty is got by giving to every unit its fullest value and thereby giving birth to a new power—the power of a larger whole. We must give up “sovereign” nations in the old sense, but with our present definition of sovereignty we may keep all the real sovereignty we have and then unite to evolve together a larger sovereignty.
