conversations.value: Arrival and Departure: Written during the middle of World War II, Arrival and Departure reflects Koestler\'s own plight as a Hungarian refugee.\nLike Koestler, the main character is a former member of the Communist party.\nHe escapes to \'Neutralia\', a neutral country based on Portugal, where Koestler himself had gone, and flees from there.\n(Stephen Spender had supposedly said of Neutralia, "Names like that should not be allowed in novels.\n") Reflecting Koestler\'s later life relationship with science, and particularly his disagreement with various movements within psychiatry, the main character emerges from treatment psychically neutered, and the critical question of the novel is how much of his later trauma and political activity is due to a small incident in his childhood.
