Postmodern films invent new categories where older conformity-and-rebellion terms fail.

Evidence

Indeed, the nonpaying of bills seems to function as the principal index for Charley’s “hipness” or “squareness” — it being understood that neither of these categories (nor those of conformity/nonconformity used above) corresponds to the logic of this film, which can be seen as an attempt very precisely to construct new categories with which to replace those older, historically dated and period-bound (uncontemporary, unpostmodern) ones. — Fredric Jameson, Postmodernism, or, The Cultural Logic…, 636

Categorization

• DEFINE: Illustrates how postmodernism constructs new semic oppositions to replace period-bound ones like conformity/nonconformity.
• XREF: Speaks directly to the reader’s stated goal of distinguishing periodizable style — connects to the earlier claim that style is the economy’s way of appearing.
