I have read Jameson's The Political Unconscious, and he seems to say that art offers an alternative, like Nietzsche's genealogy, to good and evil, moral criticism etc..
Instead of the antinomian good versus evil, it resolves the contradictions of the social whole.
Is that meaning of art inside history, or outside it? So e.g. when we say that some modern literature synthesises an experience of anomie with modernity, and language, is that meaning historical - is it, itself, meaningful dependent on modernity and anything after it, so that its re-imagining of good and evil is necessarily Marxist (if we are Marxists)?
Or does it offer a synthesis which has value independent of time, e.g. the annihilation of the work?
