Hesse wrote "Demian" with fiery prose at the height of his maturity. It's a small book, but small books often have the richest dynamism. It is clear that Hesse realized that his work had a universal character. This is attested to by the ambiguous subtitle of the novel: "A Youth Story." Ambiguous because it may include the story of youth in an individual sense, as well as the story of a generation of young people. Hesse did not want the novel to be published under his name. Rather, he chose to sign it with a pseudonym, "Sinclair," taken from the world of "Hölderlin," and he did not put his signature on it until its tenth edition. "Demian" was a novel that touched the nerve of the era with exciting accuracy, and depicted, with a sense of knowledge, the image of a youth. She believed that from among her ranks had risen the hero in whom her deepest hopes had been embodied.
