Choosing between levels of agency description is practical, not theoretical.

Evidence

The choice between these alternate descriptions — focalizations on distinct levels of abstraction — is a practical rather than a theoretical one. … If the objection arises that the descriptions of agency described above are merely alternative versions of the base-superstructure model — an economic base for Postmodernism on the one account, a social or class base on this other — then so be it, provided we understand that “base and superstructure” is not really a model of anything, but rather a starting point and a problem, an imperative to make connections, something as undogmatic as a heuristic recommendation simultaneously to grasp culture (and theory) in and for itself, but also in relationship to its outside, its content, its context, and its space of intervention and effectivity. — Fredric Jameson, Postmodernism, or, The Cultural Logic…, 873

Categorization

• DEFINE: Reframes ‘base and superstructure’ as a heuristic imperative to connect, not a fixed model - directly useful for testing whether the cultural-dominant thesis is falsifiable.
• QUESTION: If base-superstructure is only a heuristic starting point rather than a testable model, the entire cultural-dominant thesis looks unfalsifiable by design - worth pressing.
