The mask was a thing on it's own, behind which Jack hid, liberated from shame and self-conciousness.
Language fits over experience like a straight-jacket.
Maybe there is a beastโฆ maybe it's only us.
The beast was harmless and horrible; and the news must reach the others as soon as possible.
Nothing is so impenetrable as laughter in a language you don't understand.
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.
