I think that this distinction is not so well founded as it may seem. No domain of mental activity has been more disastrously involved in the war than the domain of science. Whereas art and letters have only too often been accessory stimulants of the crime, science furnished the war with its weapons, did its utmost to render them more atrocious, to widen the bounds of suffering and cruelty. I may add that even in time of peace I have always been struck by the bitterness of national sentiment displayed by men of science. Those of every nation are fond of accusing their foreign colleagues of stealing their best discoveries and forgetting to acknowledge the source. In a word, science shares in the evil passions which corrode art and letters.
On the other hand, if science needs the collaboration of all the nations, to art and letters to-day it is no less advantageous that they should abandon a position of “splendid isolation.” Without speaking of the technical advances which, in painting and music, have during the course of the nineteenth century and of the one which has begun so badly brought such sudden and enormous enrichment to the aesthetics of sight and hearing—apart from such considerations—the influence of one philosopher, one thinker, one writer, can modify the whole literature of an epoch, switching the mind on to a new road in psychological, moral, aesthetic, or social research. If any one wish to be isolated, isolated let him be! But the republic of the mind tends to enlarge its frontiers day by day. The greatest men are those who know how to embrace and fuse in a single vigorous personality the wealth that is dispersed or latent in the soul of all mankind.
Let us refrain, therefore, from limiting the idea of internationalism to the field of science. Let us give the fullest possible amplitude to the scheme. Let us form a world-wide Institute of Art, Letters and Science.

Moreover, I do not think that this foundation could
