animals, we shall find that none of them are things in which any one
nation can have exclusive property, but all are things in which the
whole world can share. Those who have any care for these things,
those who wish to see mankind fruitful in the work which men alone can
do, will take little account of national boundaries, and have little
care to what state a man happens to owe allegiance.

The importance of international cošperation outside the sphere of
politics has been brought home to me by my own experience. Until
lately I was engaged in teaching a new science which few men in the
world were able to teach. My own work in this science was based
chiefly upon the work of a German and an Italian. My pupils came from
all over the civilized world: France, Germany, Austria, Russia,
Greece, Japan, China, India, and America. None of us was conscious of
any sense of national divisions. We felt ourselves an outpost of
civilization, building a new road into the virgin forest of the
unknown. All cošperated in the common task, and in the interest of
such a work the political enmities of nations seemed trivial,
temporary, and futile.

But it is not only in the somewhat rarefied atmosphere of abstruse
science that international cošperation is vital to the progress of
civilization. All our economic problems, all the questions of
securing the rights of labor, all the hopes of freedom at home and
humanity abroad, rest upon the creation of international good-will.

So long as hatred, suspicion, and fear dominate the feelings of men
toward each other, so long we cannot hope to escape from the tyranny
of violence and brute force. Men must learn to be conscious of the
common interests of mankind in which all are at one, rather than of
