Jameson on Modernity

Fredric Jameson's four maxims of Modernity (2002) -

1. We cannot not periodize.
2. Modernity is not a concept, philosophical or otherwise, but a narrative category.
3. The narrative of modernity cannot be organized around categories of subjectivity; consciousness and subjectivity are unrepresentable; only situations of modernity can be narrated.
4. No 'theory' of modernity makes sense today unless it is able to come to terms with the hypothesis of a postmodern break with the modern.

For me, it is significant that Jameson's Preface is subtitled "Regressions of the current age."  He discusses a revival (or return, resuscitation, renewal, or whatever) of the concept of modernity, where postmodernity was a brief interlude, or, as I like to imagine it, a detour down a cul-de-sac which then necessitated an about-turn and a return to the main road.
