Written shortly after the establishment in 1919 of the League of Nations and first published in French.

As late as the seventeenth century the savants and artists of all Europe were so closely united by the bond of a common ideal that cooperation between them was scarcely affected by political events. This unity was further strengthened by the general use of the Latin language.
Today we look back at this state of affairs as at a lost paradise. The passions of nationalism have destroyed this community of the intellect, and the Latin language which once united the whole world is dead. The men of learning have become representatives of the most extreme national traditions and lost their sense of an intellectual commonwealth.
Nowadays we are faced with the dismaying fact that the politicians, the practical men of affairs, have become the exponents of international ideas. It is they who have created the League of Nations.
