Postmodernism didn’t cause Trump. It explains him.

We get the term “postmodern,” at least in its current, philosophical sense, from the title of Jean-François Lyotard’s 1979 book, “The Postmodern Condition: A Report on Knowledge.” It described the state of our era by building out Lyotard’s observations that society was becoming a “consumer society,” a “media society” and a “postindustrial society,” as postmodern theorist Fredric Jameson points out in his foreword to Lyotard’s book. Lyotard saw these large-scale shifts as game-changers for art, science and the broader question of how we know what we know. This was a diagnosis, not a political outcome that he and other postmodernist theorists agitated to bring about.

.. Jacques Derrida’s concept of “deconstruction” sought to understand language as a system capable of constantly hiding and deferring meaning, rather than a simple conduit for conveying it.
Another thinker, Jean Baudrillard, developed the concept of the “simulacrum,” a copy without an original, that leads to the “hyperreal,” a collection of signs or images purporting to represent something that actually exists (such as photos of wartime combat) but ultimately portraying a wild distortion not drawn from reality.
.. By the 1980s, conservative scholars like Allan Bloom — author of the influential “The Closing of the American Mind” — challenged postmodern theorists, not necessarily for their diagnosis of the postmodern condition but for accepting that condition as inevitable.
.. Unlike so many of today’s critics, Bloom understood that postmodernism didn’t emerge simply from the pet theories of wayward English professors. Instead, he saw it as a cultural moment brought on by forces greater than the university.
.. Bloom was particularly worried about students — as reflections of society at large — pursuing commercial interests above truth or wisdom. Describing what he saw as the insidious influence of pop music, Bloom lamented “parents’ loss of control over their children’s moral education at a time when no one else is seriously concerned with it.” He called the rock music industry “perfect capitalism, supplying to demand and helping create it,” with “all the moral dignity of drug trafficking.”
.. Kimball called “Tenured Radicals,” in his 1990 polemic against the academic left. At the heart of this accusation is the tendency to treat postmodernism as a form of left-wing politics — with its own set of tenets — rather than as a broader cultural moment that left-wing academics diagnosed.
.. it treats Lyotard and his fellows as proponents of a world where objective truth loses all value, rather than analysts who wanted to explain why this had already happened.
.. If you’re going to claim that Trumpism and alt-right relativism are consequences of the academic left’s supposition about what was happening, you must demonstrate a causal link. But commentators looking to trace these roots play so fast and loose with causality that they could easily be called postmodernist themselves.
.. It is certainly correct that today’s populist right employs relativistic arguments: For example, “identity politics” is bad when embraced by people of color, but “identitarianism” — white-nationalist identity politics — is good and necessary for white “survival.” But simply because this happens after postmodernism doesn’t mean it happens because of postmodernism
.. figures such as “intelligent design” theorist Phillip Johnson and conspiracy theorist Mike Cernovich cite the influence of postmodernist theory on their projects. Yet, as McIntyre acknowledges — and documents extensively in his book — right-wing think tanks and corporate-backed fronts — like tobacco industry “research” — had already established an “alternative facts” program for the right, long before creative misinformation entrepreneurs came around.
.. because reading postmodern theory is so notoriously difficult — partly because of how philosophical jargon gets translated, and partly because so much of the writing is abstruse and occasionally unclarifiable — an undergraduate (as in Cernovich’s case) or a layperson will almost inevitably come away with misreadings.
.. Hannah Arendt’s 1951 “The Origins of Totalitarianism”: “The ideal subject of totalitarian rule is not the convinced Nazi or the convinced communist, but people for whom the distinction between fact and fiction . . . and the distinction between true and false . . . no longer exist.” 
.. “The deliberate falsehood and the outright lie used as legitimate means to achieve political ends,” writes Arendt in her 1971 essay “Lying in Politics ,” “have been with us since the beginning of recorded history.”
.. Fredric Jameson’s reflections on conspiracy theory (“the poor person’s cognitive mapping in the postmodern age”) aren’t what’s convincing people to believe that climate change is a hoax or that the Democratic Party has been running a pedophilia ring out of a Washington pizza parlor.

.. Likewise, the claim that the Trump-Russia investigation is — as Trump said on national television — a “made-up story,” an “excuse by the Democrats for having lost an election,” is not a postmodernist critique of the evidence the Mueller investigation has gathered. So it’s a massive category error to call Trump’s post-truth politics “postmodernist.” It’s just the say-anything chicanery of the old-fashioned sales pitch.

.. it’s clear that the real enemy of truth is not postmodernism but propaganda, the active distortion of truth for political purposes.
Trumpism practices this form of distortion on a daily basis. The postmodernist theorists we vilify did not cause this; they’ve actually given us a framework to understand precisely how falsehood can masquerade as truth.
