Spring of 1931
The International Institute for Intellectual Cooperation, which is part of the League of Nations, started a program in 1931 that asked leading intellectual figures of the time to discuss in open letters exchanged between them, issues of global interest.

Summer of 1932
Albert Einstein is invited to choose a personality and correspond with them on a pressing, timeless social issue. Einstein chooses Sigmund Freud. The topic of their correspondence is the establishment of global peace and ways to avoid war for future generations.

Spring of 1933
The letters between Einstein and Freud are published in Paris in three languages (German, English, French). Unfortunately, the clouds of war had already begun to gather over Europe, and the publication was limited to just 2000 numbered copies, the circulation of which was banned in Germany.

The atrocities of war in Ukraine bring the issue of war to the forefront. What is war? Is it, perhaps, something that obeys the internal primordial impulses of humans, or is it a social phenomenon that follows broader and complex processes leading to the current phase of imperialist development, energy wars, and the redistribution of the world into spheres of influence and global dominance? Unfortunately, the letters of Einstein and Freud remain relevant.
