As many have been before me, I find metaphysical claims to be incredulous. I read these people tear down edifices, yet they seem to have a habit of replacing one for another – as if renaming it makes it disappear. Perhaps Lacan would be curious how this persists at this stage of our supposed development.
Audio: NotebookLM podcast discussing the underlying essay, The Great Substitution: From Metaphysics to Metaphysics
Because of this, I performed a survey – and then a genealogy – to trace the history of substitution. It began as a side note in The Discipline of Dis-Integration, but the pattern grew too large to ignore. Every time someone proclaims the end of metaphysics, a new one quietly takes its place. Theology becomes Reason. Reason becomes History. History becomes Structure. Structure becomes Data. The names change; the grammar doesn’t.
This essay, The Great Substitution: From Metaphysics to Metaphysics, tracks that recursion. It argues that modern thought has never killed its gods – it has merely rebranded them. Kant, Nietzsche, Heidegger, Derrida, Harari – each announced emancipation, and each built a new altar. We like to imagine that progress freed us from metaphysics, but what it really did was automate it. The temples are gone, but the servers hum.
The argument unfolds across ten short sections: from the limits of knowing, through the linguistic machinery of belief, to the modern cults of scientism, economics, psychology, and dataism. The closing sections introduce Dis-Integration – not a cure but a posture. Maintenance, not mastery. Thinking without kneeling.
If the Enlightenment promised illumination, we’ve spent the past three centuries staring directly into the light and calling it truth. This essay is my attempt to look away long enough to see what the glare has been hiding.
The Great Substitution: From Metaphysics to Metaphysics
If reason had a landscape, it would look like this card: a maze of ascending and descending staircases, forever rational yet going nowhere. Kant might have called it a Critique of Pure Geometry.
Pure Reason, the first card in the Postmodern set, isn’t so much an homage to Kant as it is a cautionary reconstruction. It honours his ambition to build a universe from deduction while quietly mourning the price of that construction: alienation from experience.

The Meta
Suspend Disbelief (3). For the next three turns, arguments cannot be resolved by evidence, only by deduction.
Audio: NotebookLM podcast of this topic.
The rule text re-enacts Kant’s method. In the Critique of Pure Reason, he cordoned off the realm of empirical evidence and tried to chart what the mind could know a priori – before experience. The card’s mechanic enforces that isolation. For three turns, players must reason in a vacuum: no appeals to observation, no touchstones of reality, only deduction.
It’s a temporary world built entirely of logic, an echo of the transcendental playground Kant envisioned. The effect is powerful but sterile – thought constructing universes that can’t sustain life.
The flavour text says it plainly:
“Reason alone constructs universes. Whether they can be lived in is another matter.”
— Immanuel Kant
That line, of course, is apocryphal, but it captures the essence of his project: reason as world-maker and prison architect in one.
The Architecture of Thought
The artwork mirrors Escher’s impossible staircases – a labyrinth of pure geometry, ordered yet uninhabitable. Each path is internally consistent, logically sound, but spatially absurd. This is Kant’s transcendental edifice made visual: coherent on paper, dizzying in practice.
The lone figure standing in the maze is the transcendental subject – the philosopher trapped within the architecture of his own cognition. He surveys the world he has built from categories and forms, unable to escape the walls of his own reason.
It’s a neat metaphor for Enlightenment hubris: the belief that reason can serve as both foundation and roof, requiring no support from the messy ground of existence.
Kant’s Double Legacy
Kant’s Critique was both the high point and the breaking point of Enlightenment rationality. It erected the scaffolding for science, ethics, and aesthetics but revealed the fault lines beneath them. His insistence that the mind structures experience rather than merely reflecting it gave birth to both modern idealism and modern doubt.
Every philosopher after him – Hegel, Nietzsche, Husserl, Derrida – has been trying either to escape or to inhabit that labyrinth differently. Pure Reason captures this tension: the glory of construction and the tragedy of confinement.
My Take
Reason is a magnificent liar. It promises order, clarity, and autonomy, but its perfection is its undoing. It abstracts itself from life until it can no longer recognise its own maker. Kant’s world is flawless and airless – a rational utopia unfit for breathing creatures.
I view Pure Reason as the archetype of the Enlightenment illusion: the attempt to found a living world on the logic of dead forms. What he achieved was monumental, but the monument was a mausoleum.
The card, then, is not just a tribute to Kant but a warning to his descendants (ourselves included): every system of thought eventually turns into an Escher print. Beautiful, consistent, and utterly unlivable.
If philosophy were a game, Wittgenstein rewrote the rulebook. Then he tore it up halfway through and told us the game was the thing itself.
“Don’t ask for the meaning; ask for the use.”
— Ludwig Wittgenstein
Language Game, the third card in my Critical Theory parody set, isn’t just homage; it’s confession. Wittgenstein is among my top five philosophers, and this card embodies why. His idea that ‘meaning is use’ unhooked language from metaphysics and tethered it to life – to the messy, unpredictable business of how humans actually speak.
The card’s text reads: Choose one: Counter target statement; or reframe it as metaphor.
At first glance, it sounds like a standard spell from Magic: The Gathering – a blue card, naturally, since blue is the colour of intellect, deceit, and control. But beneath the parody is an epistemic mirror.
To “counter” a statement is to engage in the analytic impulse – to negate, clarify, define. To “reframe it as metaphor” is the continental alternative – reinterpret, play, deconstruct. These are not two distinct acts of philosophy but the alternating heartbeat of all discourse. Every argument, every essay, every tweet oscillates between contradiction and reframing.
The sorcery lies in recognising that both are linguistic manoeuvres within the same game. Meaning is not fixed in the words themselves but in how they’re used – by whom, in what context, and to what end. Wittgenstein’s point was brutally simple: there’s no hidden substance behind language, only a living practice of moves and counter-moves.
The Shattered Face
The artwork visualises this idea: speech breaking into shards, thought fragmenting as it leaves the mouth. Meaning disintegrates even as it’s formed. Every utterance is an act of creation and destruction, coherence and collapse.
I wanted the card to look like a concept tearing itself apart whilst trying to communicate, a perfect visual for the paradox of language. The cubist angles hint at structure, but the open mouth betrays chaos. It’s communication as combustion.
Wittgenstein’s Echo
Wittgenstein once wrote, ‘Philosophy leaves everything as it is’. It sounds passive, almost nihilistic, until one realises what he meant: philosophy doesn’t change the world by building new systems; it changes how we see what’s already there.
He was the great anti-system builder, a man suspicious of his own intellect, who saw in language both the limits of thought and the infinite playground of meaning. He dismantled metaphysics not through scepticism but through observation: watch how words behave, and they’ll tell you what they mean.
In that spirit, Language Game is less an argument than an invitation – to watch the mechanics of speech, to see how our statements perform rather than merely represent.
Personal Reflection
Wittgenstein earns a place in my top five because he dissolves the boundaries that most philosophers erect. He offers no comforting totalities, no grand narratives, no moral architectures. Just language, and us inside it, flailing beautifully.
His work aligns with my larger project on the insufficiency of language – its inability to capture the real, yet its irresistible compulsion to try. Wittgenstein knew that words are our most sophisticated form of failure, and he loved them anyway.
To play Language Game is to remember that communication isn’t about arriving at truth but about keeping meaning in motion. Every conversation is a temporary alliance against silence.
The card’s instruction remains both playful and tragic: Counter target statement; or reframe it as metaphor.
This Magic: The Gathering parody trading card was the first in my Critical Theory series.
It’s an important card for me. As with sex and gender, creating a taxonomic or ontological dichotomy poses categorical challenges. Despite the insufficiency of language, it’s still all I have to attempt to classify the world. In the case of articulating the perception of reality, we can choose between idealism and realism. The problem is that it’s not either; it’s both. Reality cannot be realised without both.
Reality, we’re told, exists. That confident noun has carried a great deal of human arrogance. It has underwritten empires, sciences, and sermons. Yet somewhere between Plato’s cave and the latest TED Talk, we forgot to ask a simpler question: for whom does reality exist, and from where is it seen?
Audio: NotebookLM podcast of this topic.
The parody trading card Perspectival Realism was born from that unease. Its mechanic is simple but cruel: at the beginning of each player’s draw step, they must describe the card they drew. The enchantment persists until two players describe a card in the same way—at which point the spell collapses. In other words, consensus kills magic.
Reality is always viewed from somewhere.
—Johannes Jaeger
That rule is the metaphysics of the thing.
When a player ‘describes’ a card, they are not transmitting information; they are constructing the object in linguistic space. The moment the description leaves their mouth, the card ceases to be a piece of paper and becomes a conceptual artefact.
This mirrors the insight of Kant, Nietzsche, and every post-structuralist who ever smoked too much Gauloises: perception isn’t passive. We don’t see reality; we compose it. Language isn’t a mirror but a paintbrush. The thing we call truth is not correspondence but coherence – a temporary truce among competing metaphors.
So the card’s enchantment dramatises this process. So long as multiple descriptions circulate, reality remains vibrant, contested, alive. Once everyone agrees, it dies the death of certainty.
Philosophers have spent centuries arguing whether the world is fundamentally real (existing independent of mind) or ideal (a projection of mind). Both sides are equally tiresome.
Realism, the old bulldog of metaphysics, insists that perception is transparent: language merely reports what’s already there. Idealism, its mirror adversary, claims the opposite – that what’s “there” is mind-stuff all along. Both mistakes are symmetrical. Realism forgets the perceiver; Idealism forgets the world.
Perspectival realism refuses the divorce. It begins from the premise that world and mind are inseparable aspects of a single event: knowing. Reality is not a photograph waiting to be developed, nor a hallucination spun from neurons – it’s a relation, a constant negotiation between perceiver and perceived.
For years, I called myself a Realist™ with an asterisk. That asterisk meant I understood the observer problem: that every ‘fact’ is perspective-laden. Then I became an Idealist™ with an asterisk, meaning I recognised that mind requires matter to dream upon.
The asterisk is everything. It’s the epistemic scar left by perspectival humility – the tacit admission that every claim about the world carries a hidden coordinate: said from here. It is not relativism, but situatedness. It is the philosophical equivalent of depth perception: without the offset, there’s no vision at all.
The card’s rule – sacrifice Perspectival Realism when two players describe a card identically – captures the tragedy of modernity. The Enlightenment taught us to chase consensus, to flatten multiplicity into “objective truth.” We became addicted to sameness, mistaking agreement for understanding.
But agreement is anaesthetic. When all perspectives converge, the world ceases to shimmer; it becomes measurable, predictable, dead. The card’s enchantment disappears the moment reality is stabilised, precisely as our cultural enchantment did under the fluorescent light of ‘reason’.
To live under perspectival realism is to acknowledge that reality is not what is drawn but what is described. And the description is never neutral. It is always written from somewhere – by someone, with a vocabulary inherited from history and stained by desire.
As long as multiple descriptions coexist, the game remains alive. The moment they fuse into one, the spell is broken, and the world returns to grey.
Bernardo Kastrup’s analytic idealism reminded me that consciousness might be primary, but perspectival realism refuses to pledge allegiance. It keeps both flags tattered but flying. The world exists, yes, but only ever for someone.
The enchantment, then, is not belief but perspective itself. So long as difference endures, the game continues.
When drawn, this card alters perception itself. It reminds the player that truth is not something one finds under a rock but something one polishes into shape. Each metaphor becomes a spell; each keyword a crutch thrown aside.
Those who wield the Constructivist Lens see not “facts,” but fictions so useful they forgot to call them that. Reality wobbles politely to accommodate belief.
“Knowledge is not a copy of reality but a tool for coping with it.” — Richard Rorty
In game terms: Tap to reframe existence as interpretation. Duration: until the next disagreement.
I finished Mattias Desmet’s The Psychology of Totalitarianism, which I mentioned the other day. Unfortunately, my initial optimism was premature. Everything I enjoyed was front-loaded: the first four chapters set up a promising critique of mechanistic rationality and the collapse of shared meaning. Then the book turned into a long, therapeutic sermon. I should have stopped at Chapter 4 and saved myself the sunk-cost regret.
It isn’t that nothing follows; it’s just that what follows is so thin that the cost-benefit ratio goes negative. Once Desmet moves from diagnosis to prescription, the argument collapses into a psychologist’s worldview: an entire civilisation explained through mass neurosis and healed through better intuition. He builds his case on straw versions of reason, science, and modernity, so his ‘cure’ can look revelatory.
The trouble is familiar. Having dismantled rationalism, Desmet then installs intuition as its replacement – an epistemic monarchy by another name. His appeal to empathy and connection reads less like philosophy and more like professional self-promotion. The therapist can’t stop therapising; he privileges the psychological lens over every other possibility.
The result is a reductionist parascience dressed as social theory. The totalitarian mind, in Desmet’s telling, isn’t political or structural but psychological – a patient waiting for insight. I don’t doubt his sincerity, only his scope. It’s what happens when a discipline mistakes its vocabulary for the world.
Desmet’s project ultimately re-enchants what it claims to critique. He wants rationalism redeemed through feeling, order reborn through connection. Dis-Integrationism stops short of that impulse. It accepts fracture as the permanent condition – no higher synthesis, no therapeutic finale. Where Desmet sees totalitarianism as a collective pathology awaiting treatment, I see it as reason’s own reflection in the mirror: a system trying to cure itself of the only disease it knows, the need to be whole.
Besmet, a Belgian psychologist with a background in statistics, begins not with tyranny but with epistemology – with how the Enlightenment’s dream of objectivity curdled into the managerial nightmare we now inhabit. The first half of the book reads like a slow unmasking of Scientism: how numbers became our gods, and graphs, our catechisms.
Written before COVID-19 but finished during it, his argument turns pandemic data into theatre – a performance of certainty masking deep confusion. The daily tally became ritual sacrifice to the idol of ‘evidence-based’ policy. His point, and mine, is that totalitarianism no longer needs gulags; it thrives in dashboards and KPIs.
Desmet’s frame intersects beautifully with my own thesis: that obedience today is internalised as reasonableness. Freedom has been recast as compliance with ‘the data’. We surrender willingly, provided the orders come in statistical form.
This is why even Agile™ management and its fetish of ‘velocity’ reek of the same mechanistic faith. Every sprint promises deliverance through quantification; every retrospective is a bureaucratic confession of inefficiency. The cult of metrics is not merely a managerial fad – it is the metaphysics of our time. The problem is at once ontological and epistemological: we mistake the measure for the thing itself, and in doing so, become measurable.
It’s a rare pleasure to encounter a fellow dissident of the numerical faith – a man who sees that the spreadsheet has replaced the sceptre.
I’ve just added a new entry to my Anti-Enlightenment corpus, bringing the total to seven – not counting my latest book, The Illusion of Light, that summarises the first six essays and places them in context. This got me thinking about what aspects of critique I might be missing. Given this, what else might I be missing?

1. Objectivity Is Illusion: An Operating Model of Social and Moral Reasoning
Published September 2025
Objectivity, in the social and moral sense, is a performance – a consensus mechanism mistaken for truth. This essay maps how “objectivity” operates as a scaffold for Enlightenment rationality, masking moral preference as neutral judgment. It introduces a five-premise model showing that what we call objectivity is merely sustained agreement under shared illusions of coherence. The argument reframes moral reasoning as provisional and participatory rather than universal or fixed.
2. Rational Ghosts: Why Enlightenment Democracy Was Built to Fail
Published October 2025 The Enlightenment built democracy for rational ghosts – imagined citizens who never existed. This essay dissects six contradictions at the foundation of “rational” governance and shows why democracy’s collapse was prewritten in its metaphysics. From mathematical impossibility to sociological blindness, it charts the crisis of coherence that modern politics still calls freedom. → Read on Zenodo
3. Temporal Ghosts: Tyranny of the Present
Published October 2025 Modern democracies worship the now. This essay examines presentism – the systemic bias toward immediacy – as a structural flaw of Enlightenment thinking. By enthroning rational individuals in perpetual “decision time,” modernity erased the unborn from politics. What remains is a political theology of the short term, collapsing both memory and imagination. → Read on Zenodo
4. Against Agency: The Fiction of the Autonomous Self
Published October 2025 “Agency” is not a metaphysical faculty – it’s an alibi. This essay dismantles the myth of the autonomous self and reframes freedom as differential responsiveness: a gradient of conditions rather than a binary of will. Drawing on philosophy, neuroscience, and decolonial thought, it argues for ethics as maintenance, not judgment, and politics as condition-stewardship. → Read on Zenodo
5. The Discipline of Dis-Integration: Philosophy Without Redemption
Published October 2025
This essay formalises Dis-Integrationism – a philosophical method that refuses synthesis, closure, and the compulsive need to “make whole.” It traces how Enlightenment reason, deconstruction, and therapy culture all share a faith in reintegration: the promise that what’s fractured can be restored. Against this, Dis-Integrationism proposes care without cure, attention without resolution – a discipline of maintaining the broken as broken. It closes the Anti-Enlightenment loop by turning critique into a sustained practice rather than a path to redemption.
6. The Myth of Homo Normalis: Archaeology of the Legible Human
Published October 2025
Modernity’s most persistent myth is the “normal” human. This essay excavates how legibility – the drive to measure, categorise, and care – became a form of control. From Quetelet’s statistical man to Foucault’s biopower and today’s quantified emotion, Homo Normalis reveals the moral machinery behind normalisation. It ends with an ethics of variance: lucidity without repair, refusal without despair.
7. The Will to Be Ruled: Totalitarianism and the Fantasy of Freedom
Published October 2025
This essay examines how the Enlightenment’s ideal of autonomy contains the seed of its undoing. The rational, self-governing subject – celebrated as the triumph of modernity – proves unable to bear the solitude it creates. As freedom collapses into exhaustion, the desire for direction re-emerges as devotion. Drawing on Fromm, Arendt, Adorno, Reich, Han, and Desmet, The Will to Be Ruled traces the psychological gradient from fear to obedience, showing how submission is moralised as virtue and even experienced as pleasure. It concludes that totalitarianism is not a deviation from reason but its consummation, and that only through Dis-Integrationism – an ethic of maintenance rather than mastery – can thought remain responsive as the light fades.
Axis: Theological / Metaphysical Core Question: What remains sacred once transcendence is dismantled?
Concept: This essay would trace how Enlightenment humanism replaced God with reason, only to inherit theology’s structure without its grace. It might read Spinoza, Kant’s moral law, and modern technocracy as secularised metaphysics – systems that still crave universal order. Goal: To show that disenchantment never erased faith; it simply redirected worship toward cognition and control. Possible subtitle:The Enlightenment’s Unconfessed Religion.
9. The Aesthetic Contract: Beauty as Compliance
Axis: Aesthetic / Affective Core Question: How did beauty become moral instruction?
Concept: From Kant’s Critique of Judgment to algorithmic taste cultures, aesthetic judgment serves social order by rewarding harmony and punishing dissonance. This essay would expose the politics of form – how beauty trains attention and regulates emotion. Goal: To reclaim aesthetics as resistance, not refinement. Possible subtitle:Why Modernity Needed the Beautiful to Behave.
10. The Uncounted World: Ecology and the Non-Human
Axis: Ecological / Post-Human Core Question: What happens when the world refuses to remain background?
Concept: Here you dismantle the Enlightenment split between subject and nature. From Cartesian mechanism to industrial rationalism, the natural world was cast as resource. This essay would align Dis-Integrationism with ecological thinking – care without mastery extended beyond the human. Goal: To reframe ethics as co-maintenance within an unstable biosphere. Possible subtitle:Beyond Stewardship: Ethics Without Anthropos.
11. The Fractured Tongue: Language Against Itself
Axis: Linguistic / Semiotic Core Question: How does language betray the clarity it promises?
Concept: Every Anti-Enlightenment text already hints at this: language as both the instrument and failure of reason. Drawing on Nietzsche, Derrida, Wittgenstein, and modern semiotics, this essay could chart the entropy of meaning – the collapse of reference that makes ideology possible. Goal: To formalise the linguistic fragility underlying every rational system. Possible subtitle:The Grammar of Collapse.
12. The Vanished Commons: Between Isolation and Herd
Axis: Communal / Social Ontology Core Question: Can there be community without conformity?
Concept: This would return to the psychological and political threads of The Will to Be Ruled, seeking a space between atomised autonomy and synchronized obedience. It might turn to Arendt’s notion of the world between us or to indigenous and feminist relational models. Goal: To imagine a non-totalitarian togetherness – a responsive collective rather than a collective response. Possible subtitle:The Ethics of the Incomplete We.
* These essays may never be published, but I share this here as a template to further advance the Anti-Enlightenment project and fill out the corpus.
Not the darkness after the light, but the shadow the light forgot it cast
The Enlightenment promised light. What it delivered was fluorescence – bright, sterile, and buzzing with the sound of its own reason.
The Anti-Enlightenment Project gathers a set of essays, fragments, and quotations tracing how that light dimmed – or perhaps was never as luminous as advertised. It’s less a manifesto than a map of disintegration: how agency became alibi, how reason became ritual, and how modernity mistook motion for progress.

This isn’t a war on knowledge, science, or reason – only on their misappropriation as universal truths. The Anti-Enlightenment simply asks what happens when we stop pretending that the Enlightenment’s “light” was neutral, natural, or necessary.
It’s not reactionary. It’s diagnostic.
The Enlightenment built the modern world; the Anti-Enlightenment merely asks whether we mistook the glare for daylight.
Are you rational, or merely rehearsing your tribe’s catechism? Bayes’ theorem insists we should all update our beliefs the same way when presented with the same evidence. Yet in today’s political divide, identical events harden opposing convictions. The problem isn’t the math—it’s the priors. When your starting assumptions are inherited, acculturated, or indoctrinated, no amount of “evidence” will move you into enemy territory.
A Bayesian Sketch of the Divide
Let be a contested claim (pick your poison: “the election was fair,” “immigration helps,” whatever).
People in Camp R and Camp B begin with different priors and . That’s acculturation if you’re being polite, indoctrination if you’ve run out of patience.
They observe evidence (news, a court ruling, a video clip, a statistic).
They update:
posterior odds = prior odds ×
Except they don’t, not cleanly, because trust in sources warps the likelihoods.
Video: Jonny Thompson on Bayes’ Theorem. I love Jonny’s content, which is why I reference it so often. He and I have such different philosophical worldviews. Vive la différence (or différance).
Why this locks in polarisation
1. Wildly different priors. If Camp R starts at and Camp B at , then even moderately pro- evidence (say likelihood ratio ) yields:
R: prior odds
B: prior odds
Same evidence, one camp “settled,” the other still unconvinced. Repeat ad infinitum, preferably on primetime.
2. Identity-weighted likelihoods. People don’t evaluate ; they evaluate . Disconfirming evidence is down-weighted by a factor . This is called “being rational” on your own planet and “motivated reasoning” on everyone else’s.
3. Different hypothesis sets. Camps don’t just disagree on ; they entertain different s. If one side’s model includes “coordinated elite malfeasance” and the other’s does not, then identical data streams update into different universes.
4. Selective exposure = selection bias. Evidence isn’t i.i.d.; it’s curated by feeds, friends, and fury. You are sampling from your own posterior predictive distribution and calling it “reality.”
5. Asymmetric loss functions. Even if beliefs converged, choices won’t. If the social cost of dissent is high, the decision threshold moves. People report a “belief” that minimises ostracism rather than error.
6. No common knowledge, no convergence. Aumann told us honest Bayesians with common priors and shared posteriors must agree. Remove either—common priors or the “we both know we both saw the same thing” bit—and you get the modern news cycle.
“Acculturation” vs “Indoctrination”
Same mechanism, different moral valence. Priors are installed by families, schools, churches, unions, algorithms. Call it culture if you approve of the installers; call it indoctrination if you don’t. The probability calculus doesn’t care. Your tribal totems do.
Two quick toy moves you can use in prose
Likelihood hacking: “When evidence arrives, the tribe doesn’t deny the datum; it edits the likelihoods. ‘If my side did it, it’s an outlier; if your side did it, it’s a pattern.’ This is not hypocrisy; it’s a parameter update where the parameter is loyalty.”
Posterior divergence despite ‘facts’: “Give two citizens the same court ruling. One updates towards legitimacy because courts are reliable; the other away from legitimacy because courts are captured. The ruling is constant; the trust vector is not.”
If one wanted to reduce the split (perish the thought)
Forecast, don’t opine. Run cross-camp prediction markets or calibration tournaments. Bayes behaves when you pay people for accuracy rather than performance art.
Adversarial collaboration. Force both sides to pre-register what evidence would move them and how much. If someone’s for disconfirming evidence is effectively zero, you’ve identified faith, not inference.
Reference classes, not anecdotes. Pull arguments out of the single-case trap and into base-rate land. Yes, it’s boring. So is surgery, but people still do it.
The punchline
Polarisation isn’t the failure of reason; it’s what happens when reason is strapped to identity. Priors are social. Likelihoods are political. Posteriors are performative. You can call it acculturation if you want to feel civilised, indoctrination if you want to throw a brick, but either way you’re watching Bayes’ theorem run inside a culture war. The maths is sober; the humans are not.
