These letters give the account of Rilke's own state of mind and of his final approach to the threshold of his great works. They show the rapid change he underwent after his reaction to the first excitement of the war; how his dismay at the cruelty and confusion of war helped to render the poet in him speechless for many years; how he nevertheless characteristically held to his own fundamental views throughout war and revolution and in spite of everything retained his belief in the capacity of humanity to create for itself a better future.
