The diplomatic office should be conceived as having the function to represent not only the special national interest of the respective country, but also, on an equal plane, its participation in all the activities and interests which are common to the nations of the world. The legations and embassies should be provided with a personnel of attachés not only for political and military affairs, but for commerce, education, science and social legislation. All these matters are already dealt with to some extent by common action among the nations. The sending of ministers as delegates to international technical conferences has often been criticized as importing into such conferences the narrow, separatist point of view of diplomatic politics. It should be exactly the other way; participation in such conferences ought to impart to diplomats a broad spirit of coöperation instead of a desire to maintain intact a theoretical isolation. That is the essence of the matter. As long as it is supposed that by jealously scrutinizing every international relationship from the point of view of abstract political independence, and assuming that it is best to make the very least possible contribution of energy and coöperation, the national interest can be most promoted; so long will diplomatic action continue on a strained basis, always being painfully conscious of the potential enmity among nations. But when it is realized that in nearly every case the national interest, or the interest of the people of the nation which ought to be synonymous therewith, is best advanced by whole-souled coöperation in constructive work in commerce, industry, science and the arts, then the political factor of diplomatic rivalry will assume more just proportions as compared with the other interests of humanity. This borders upon a very broad subject dealing rather with general international policy than with the specific problems we were considering; and yet we ought to be aware of this background. We need not give up our conviction that the autonomy of the national state must be preserved and that each political society shall dispose of its own affairs within its borders as its wisdom and judgment may dictate, free from intervention from without. But complete freedom of local self-determination can rest only upon a universal recognition of that right in all others, in a spirit of confidence and security engendered by the absence of intrigue and secret ambitions. In a still greater measure does the happiness of the national state depend on free and full coöperation with all others in all pursuits, activities and interests common to humanity and in making the earth a place for dignified and happy human life. Unless diplomacy looks forward to this and helps to bring it about, it will remain ensnared in the old practices which ever lead only to barren results.
