Paris, 1918: In the last year of his life, Guillaume Apollinaire published "L' esprit nouveau et les poètes" (The New Spirit and the Poets), a modern art manifesto. "I don’t believe", said Apollinaire, "that social developments will ever go so far that one will not be able to speak of national literature….From ethnic and national differences are born the variety of literary expressions, and it is that very variety which must be preserved." My favourite sentence from this manifesto is: "It must not be forgotten that it is perhaps more dangerous for a nation to allow itself to be conquered intellectually than by arms."
