Allen Mendenhall writes for the Martin Center about the academic debate surrounding the disputed term “cultural Marxism.”

Samuel Moyn, a Yale law professor, recently asked, “What is ‘cultural Marxism?’” His answer: “Nothing of the kind actually exists.” Moyn attributes the term cultural Marxism to the “runaway alt-right imagination,” claiming that it implicates zany conspiracy theories and has been “percolating for years through global sewers of hatred.”

Alexander Zubatov, an attorney writing in Tablet, countered that the “somewhat unclear and contested” term cultural Marxism “has been in circulation for over forty years.” It has, moreover, “perfectly respectable uses outside the dark, dank silos of the far right.” He concluded that cultural Marxism is neither a “conspiracy” nor a “mere right-wing ‘phantasmagoria,’” but a “coherent intellectual program, a constellation of dangerous ideas.”

In this debate, I side with Zubatov. Here’s why.

Despite the bewildering range of controversies and meanings attributed to it, cultural Marxism (the term and the movement) has a deep, complex history in Theory. The word “Theory” (with a capital T) is the general heading for research within the interpretative branches of the humanities known as cultural and critical studies, literary criticism, and literary theory—each of which includes a variety of approaches from the phenomenological to the psychoanalytic. In the United States, Theory is commonly taught and applied in English departments, although its influence is discernable throughout the humanities.

A brief genealogy of different schools of Theory—which originated outside English departments, among philosophers and sociologists for example, but became part of English departments’ core curricula—shows not only that cultural Marxism is a nameable, describable phenomenon, but also that it proliferates beyond the academy.
