21st Century Marxism

A living, evolving theoretical tradition that applies Marx's method to the specific material conditions of the contemporary moment: digital monopoly capitalism, the climate crisis, the platform economy, and the resurgence of neofascism. It rejects the notion that Marxism is a relic of the 19th century, frozen in the pages of Capital, and instead treats it as a toolkit for diagnosing the present. 21st Century Marxism analyzes how Big Tech extracts data as a new form of primitive accumulation; how social media algorithms proletarianize attention; how the military-entertainment complex colonizes consciousness; and how the post-2008 world has normalized precarity as a permanent condition. It also delivers a devastating verdict on the contemporary right: that neoliberalism has exhausted its reformist facade and is decaying openly into neofascism, with the thin veneer of liberal democracy cracking across the Global North.

21st Century Marxism *Example: A 21st Century Marxist examines TikTok. They don't moralize about screen time. They analyze the platform as a digital factory: users perform unpaid labor generating content and data, which is algorithmically sorted and sold to advertisers. The "For You Page" is not entertainment; it is a continuous workflow. The dopamine hits are not pleasure; they are piece-rate wages. The theory further notes that this digital factory coexists with the resurgence of open white supremacy, seeing both as symptoms of a capitalism that can no longer stabilize itself through reform.*

21st Century Epistemicide

The ongoing, accelerated destruction of diverse knowledge systems in the digital age, driven by algorithms, platform monopolies, and the attention economy. If historical epistemicide was missionaries burning libraries, 21st Century Epistemicide is the recommendation algorithm burying everything outside its optimized categories. It's Wikipedia in English becoming the default "truth" while oral traditions vanish. It's Twitter amplifying hot takes while erasing context. It's the subtle, continuous message that if your knowledge isn't searchable, quantifiable, and algorithm-friendly, it doesn't count. The killing is cleaner now—no smoke, just silence.

"My grandmother's herbal remedies don't have a Wikipedia page, so my nephew Googles his symptoms and trusts the first result. That's 21st Century Epistemicide: a thousand years of knowledge erased because it couldn't be SEO-optimized."

21st Century Postmodernism

The contemporary evolution of postmodern thought, adapted to the conditions of the digital age—social media, information saturation, algorithmic reality, and the collapse of traditional authority structures. 21st Century Postmodernism retains the core postmodern insights (the constructed nature of truth, the role of power in knowledge, the critique of grand narratives) while applying them to new phenomena: viral misinformation, identity politics, platform capitalism, and the fragmentation of shared reality. It's postmodernism for the age of Twitter, where everyone has a platform and no one has authority; for the age of deepfakes, where seeing is no longer believing; for the age of echo chambers, where truth is what your tribe says it is. 21st Century Postmodernism is less a philosophical movement than a description of how we actually live—in a world where grand narratives have collapsed and been replaced by infinite micro-narratives, all competing for attention, none able to command consensus.

Example: "He used to think postmodernism was an academic fad. Then he watched his Facebook feed: competing realities, each side accusing the other of being brainwashed, no shared facts, no common ground. 21st Century Postmodernism wasn't a theory anymore; it was his daily life. The grand narratives were dead; only the tribes remained."

21st Century Relativism

The contemporary form of relativism, adapted to the conditions of the digital age—where competing truths proliferate, authority is fragmented, and shared reality seems to dissolve. 21st Century Relativism is less a philosophical doctrine than a description of how we live: in a world where everyone has a platform, no one has authority, and truth is what your tribe says it is. It's the relativism of echo chambers, of filter bubbles, of alternative facts. 21st Century Relativism is both a description (this is how things are) and a problem (how do we live together when we can't agree on reality?). It's the philosophy of our time, whether we like it or not.

Example: "He watched his Facebook feed: two sides, two realities, no common ground. 21st Century Relativism wasn't a choice; it was his environment. Everyone had their truth; no one had the truth. He'd learned to navigate multiple realities—not because he wanted to, but because there was no alternative."
