In this article, we will try to trace, illuminate and articulate the “scientific break” from the objective to subjective value that occurred when economic science progressed from its classical period, proceeding by its critique (of political economy) and finishing up with the marginalist revolution.
Our thesis and elaboration in the third part will be that this endless displacement is a consequence of inadequate concept-building, one that can be theoretically outlined with the misapprehension and loss of the concept of real abstraction in economic science—a problem already highlighted by Marx and emphasized by Theodor W. Adorno and “The New Reading of Marx”.
What distinguishes Marx from marginalists and mainstream economists is precisely this shift in the object of knowledge [Erkenntnisobjekt], whose effects we chose to call the subtraction of the qualitative.
