What more do we need than fair competition to constitute the coöperative international life which we dreamed yesterday and now must consider, not merely as a dream, but as the only alternative to a future of horror? Free trade has been not unnaturally urged as at least one condition. Tariffs certainly isolate. To say to a country: "You shall manufacture nothing unless you own the raw material; you shall sell nothing unless at prices which I fix," is likely to provoke the reply: "Then I must acquire lands in which raw materials are found; I must acquire colonies which will buy my products." Trade agreements mean coöperation for those within, unless they are one-sided and made under duress; in any case they are exclusive of those without. Free trade, the open door, seems to offer a better way. But free trade in name is not free trade unless the parties are really free--free from ignorance, from pressure of want. If one party is weak and the other unscrupulous; if one competitor has a lower standard of living than the other, freedom of trade will not mean genuine coöperation. Such coöperation as means good for all requires either an equality of conditions between traders and laborers of competing nations and of nations which exchange goods, or else an international control to prevent unfair competition, exploitation of weaker peoples, and lowering of standards of living. Medical science is giving an object lesson which may well have a wide application. It is seeking to combat disease in its centers of diffusion. Instead of attempting to quarantine against the Orient, it is aiding the Orient to overcome those conditions which do harm alike to Orient and Occident. Plague, anthrax, yellow fever, cannot exist in one country without harm to all. Nor in the long run can men reach true coöperation so long as China and Africa are a prize for the exploiter rather than equals in the market. Not merely in the political sense, but in its larger meanings democracy here is not safe without democracy there. Education, and the lifting of all to a higher level, is the ultimate goal. And until education, invention, and intercommunication have done their work of elevation, international control must protect and regulate.
