No human endeavour can ever be wholly good... it must always have a cost.
Art is partly communication, but only partly. The rest is discovery.
I do think that art that doesn't communicate is useless.
Put simply the novel stands between us and the hardening concept of statistical man. There is no other medium in which we can live for so long and so intimately with a character. That is the service a novel renders.
What a man does defiles him, not what is done by others.
However you disguise novels, they are always biographies.
