"One, None and a Hundred-thousand" is a philosophical novel by the Italian writer Luigi Pirandello. It examines the oft-asked question of how other people perceive us. The main character Vitangelo Moscarda discovers, by way of a completely irrelevant question, that his wife poses to him that everyone he knows, everyone he has ever met, has constructed a Vitangelo persona in their own imagination and that none of these personas corresponds to the image of Vitangelo that he himself has constructed and believes himself to be. The novel was Pirandello's last novel and it took him more than 15 years to write.
