It sounds as though success is a necessary aspect of innovation - because what is it if you have all those 5 components and they lead to nothing? That leaves me wondering when self-conscious experiment (or departure from a conservative norm) becomes an innovation. Does it need to be judged to be significant, applauded and assimilated into what is then considered a better, broader church?
Guess it depends on how you define success. Perec was immensely innovative and imaginative —and I should have added "imagination" as a sixth factor.
La disparition is an amazing feat, is considered a significant addition to the canon of 20th century literature and is applauded, but I'm not sure it works as a novel, partly because it feels like the lipogrammatic exercice takes precedence over story — and Perec is a very good storyteller, as shown in his other novel,
La vie mode d'emploi.
Another example of self-conscious experiment that is also departure from a conservative norm, but very different in reach, impact and influence than
La disparition, is James Joyce's
Ulysses. It's interesting to note that the decade following the 14-18 war was one of immense innovation in literature, with, next to Joyce's, such works as Kafka's
The Trial, Proust's
A la recherche du temps perdu, Hasek's
The Good Soldier Svejk, Thomas Mann's
The Magic Mountain, Virginia Woolf's
Mrs Dalloway, Herman Hesse's
Siddharta, Hemingway's
A Farewell to Arms, Svevo's
La coscienza di Zeno, Remarque's
All Quiet on the Western Front, Moravia's Gli indifferenti, the short stories of Langston Hughes, etc. And we're just talking European and American literature here, with a bunch of other interesting and innovative stuff happening elsewhere.
All the works are immensely innovative, but each in its own way. There's no universal criteria of innovation at work that unites them all, that can be applied to all. Each is part self-conscious experiment — but sitting at a desk every single day at the same time to write two lines, a paragraph or a page for months if not years (i.e., the very act of writing) is in itself a self-conscious experiment. And each, in its own way, depart from a conservative norm, but departing from a conservative norm isn't necessarely the point of each, but simply a consequence of having to tell the story a certain way.
