For the first time in history, across much of the world, to be foreign is a perfectly normal condition. It is no more distinctive than being tall, fat or left-handed. Nobody raises an eyebrow at a Frenchman in Berlin, a Zimbabwean in London, a Russian in Paris, a Chinese in New York.rnThe desire of so many people, given the chance, to live in countries other than their own makes nonsense of a long-established consensus in politics and philosophy that the human animal is best off at home. Philosophers, it is true, have rarely flourished in foreign parts: Kant spent his whole life in the city of Konigsberg; Descartes went to Sweden and died of cold. But that is no justification for generalising philosophers' conservatism to the whole of humanity.
