Paul Nash, artist, on telling the truth to warmongers about war, writing to his wife from the WW1 Western Front front on 16 November 1917: "I am no longer an artist. I am a messenger who will bring back word from the men who are fighting to those who want the war to go on for ever. Feeble, inarticulate will be my message, but it will have a bitter truth and may it burn their lousy souls." [1, 2]
