> The Nobel Prize in Literature […] is awarded annually, since 1901, to an author from any country who has, in the words of the will of Swedish industrialist Alfred Nobel, "in the field of literature, produced the most outstanding work in an idealistic direction"
> Alfred Nobel's guidelines for the prize, stating that the candidate should have bestowed "the greatest benefit on mankind" and written "in an idealistic direction," have sparked much discussion. In the early history of the prize, Nobel's "idealism" was read as "a lofty and sound idealism." The set of criteria, characterised by its conservative idealism, holding church, state, and family sacred, resulted in prizes for Bjørnstjerne Bjørnson, Rudyard Kipling, and Paul Heyse. During World War I, there was a policy of neutrality, which partly explains the number of awards to Scandinavian writers. In the 1920s, "idealistic direction" was interpreted more generously as "wide-hearted humanity," leading to awards for writers like Anatole France, George Bernard Shaw, and Thomas Mann. In the 1930s, "the greatest benefit on mankind" was interpreted as writers within everybody's reach, with authors like Sinclair Lewis and Pearl Buck receiving recognition. From 1946, a renewed Academy changed focus and began to award literary pioneers like Hermann Hesse, André Gide, T. S. Eliot, and William Faulkner. During this era, "the greatest benefit on mankind" was interpreted in a more exclusive and generous way than before. Since the 1970s, the Academy has often given attention to important but internationally unnoticed writers, awarding writers like Isaac Bashevis Singer, Odysseus Elytis, Elias Canetti, and Jaroslav Seifert.
