Marx’s theory must be continuously developed because capitalism constantly changes.

Evidence

There is a view that everything that Marxism needs is already there in Capital : and that, if you stare hard enough at it, it will—like the hidden books of the Bible—yield up all its secrets, a theory of everything. I don’t subscribe to this thesis in its literal form. Apart from anything else, it denies one of the central premises of Capital— that the capitalist mode of production is constantly developing, and this in turn requires a continuous labor of theoretical development and clarification. — Hall, Stuart, Essential Essays, Volume 1, 475

Categorization

• DEFINE: Clarifies Hall’s stance that Capital is a terrain of concepts, not a finished theory of everything.
• XREF: Connects to the general problem in the Frankfurt School reading of treating Marx as closed system vs. open problematic.
