The idea of internationalism implies certain changes in the external relations of nations which, whatever the form internationalism will take on its political side, are not difficult to perceive. These in turn imply internal changes. We might readily outline or psychologically analyze what could be called the mood of internationalism, in order to see its relations to education. It contains a number of factors, more or less related to one another. _First_, there is a recognition of a world of growing, living historical entities which we call nations; and this recognition implies new understanding and an enrichment of knowledge. _Second_, there is a change in the consciousness of nations, slow but visible, by which they become more willing to investigate freely and fairly their own place in history, understand their own desires, functions, virtues, faults, the value of their culture and civilization. Without such an attitude all talk of internationalism in any real sense is idle. _Third_, there is a new and different practical interest. We begin to conceive our world as a world of complex practical relations, and this idea of a practical world is likely to become one of the leading thoughts of the future. _Fourth_, by extending, so to speak, this idea of a world of practical relations, we idealize a world in which there is a common interest in great international achievements,--a world devoted more than it is now to cooerdinated efforts to accelerate progress, more conscious of the needs of a distant future, perhaps, or even of an ideal of universal efficiency as a means of realizing some one world purpose or many good purposes. This is not now, as it once might have been called, merely an Utopian dream. In some slight degree it is already being accomplished. _Fifth_, social and moral feelings are widened in scope, and must be still further extended; it is in the form of the _democratic spirit_, that these feelings must find expression. And this democratic spirit is on one side practical, but it is also something more than the emergence of the common mind; it is the _aristocratic idea carried out universally_ that we look forward to, an enthusiasm for all true values, a mood and activity in which all people participate. _Sixth_, there is a necessary attitude toward world organization or world government, according to which we think of world government or world organization as a means of accomplishing results which fulfill fundamental desires and purposes of the peoples of the earth; as a growing structure, something to be added to and improved. _Seventh_, if so general a tendency and demand may be made clear, there is a philosophical mood, which must be made a part of the ideal and the attitude of the future, _if that future is to realize even the practical hopes of the world_. This philosophical attitude is first of all a way of living comprehensively and more universally, in the world both of facts and of ideas.
