The economics of the modern world make it inevitable that thinkers on public questions, particularly on economic questions, should frame their thoughts in world terms, and that the practical plans for the organization and direction of human affairs should be built around an idea which includes these three elements: 1. _Any workable plan for the organization of the world must have an economic foundation._ 2. _Such a plan must include all of the economically essential portions of the world._ It will be ineffective if it is confined to any one nation, to any one group of nations, or to any one continent. 3. _Such a plan must rely, for its fulfillment, on world thinking and world organization._ These propositions do not imply that economic forces and world organization must become the centers of exclusive attention. There are potent forces, other than economic ones, and there are forms of local organization that must be developed or perpetuated as a matter of course. But for the moment the economic forces and the world phases of organization have assumed a position of primary importance. [Footnote 2: The Manchester Guardian Commercial, Supplement for April 20, 1922, page IV, carries an advertisement signed by Sir Charles W. Macara, Chairman and Managing Director of Henry Bannerman and Sons, Ltd., Chairman of the Manchester Cotton Employers Association, etc., which contains a very forceful presentation of this point. "It is impossible for any country to expect to win economic success at the expense or in total indifference to the success of others.... The good of one country is bound up with the good of another, and it is only by studying what will be mutually advantageous that we shall find the key to our good fortune.... The whole world is interdependent, and you cannot injure one member of the international body without injuring all the rest."] 5. _The League of Nations Failure_
