“There is no use for us to shut our eyes to realities. The fact remains that the policy of collective security based on sanctions has been tried out, as indeed we were bound to try it out unless we were prepared to repudiate our obligations and say, without having tried it, that the whole system of the League and the Covenant was a sham and a fraud. That policy has been tried out and it has failed to prevent war, failed to stop war, failed to save the victim of the aggression.”

Nobel Prize Speech (1954)
Context: Things may not be immediately discernible in what a man writes, and in this sometimes he is fortunate; but eventually they are quite clear and by these and the degree of alchemy that he possesses he will endure or be forgotten. Writing, at its best, is a lonely life. Organizations for writers palliate the writer's loneliness but I doubt if they improve his writing. He grows in public stature as he sheds his loneliness and often his work deteriorates. For he does his work alone and if he is a good enough writer he must face eternity, or the lack of it, each day. For a true writer each book should be a new beginning where he tries again for something that is beyond attainment. He should always try for something that has never been done or that others have tried and failed. Then sometimes, with great luck, he will succeed.
