"When the United States entered the war in 1917, Bertrand Russell wrote an article to the effect that the purpose of bringing American troops to Britain was to break strikes. For this he was sent very properly to prison for six months. He was given preferential treatment in prison, pens and paper, reading and writing materials, and while there he wrote one of his better books. It enabled him to concentrate better. When he read Lytton Strachey's Eminent Victorians, it made him laugh so much that a warder had to remind him that prison was supposed to be a place of punishment."
