Let us begin with the heresy: Truth is a rhetorical artefact. Not a revelation. Not a metaphysical essence glimmering behind the veil. Just language — persuasive, repeatable, institutionally ratified language. In other words: branding.

This is not merely a postmodern tantrum thrown at the altar of Enlightenment rationalism. It is a sober, if impolite, reminder that nearly everything we call “knowledge” is stitched together with narrative glue and semantic spit. Psychology. Neuroscience. Ethics. Economics. Each presents itself as a science — or worse, a moral imperative — but their foundations are built atop a linguistic faultline. They are, at best, elegant approximations; at worst, dogma in drag.

Let’s take psychology. Here is a field that diagnoses your soul via consensus. A committee of credentialed clerics sits down and declares a cluster of behaviours to be a disorder, assigns it a code, and hands you a script. It is then canonised in the DSM, the Diagnostic Scripture Manual. Doubt its legitimacy and you are either naïve or ill — which is to say, you’ve just confirmed the diagnosis. It’s a theological trap dressed in the language of care.

Or neuroscience — the church of the glowing blob. An fMRI shows a region “lighting up” and we are meant to believe we’ve located the seat of love, the anchor of morality, or the birthplace of free will. Never mind that we’re interpreting blood-oxygen fluctuations in composite images smoothed by statistical witchcraft. It looks scientific, therefore it must be real. The map is not the territory, but in neuroscience, it’s often a mood board.

And then there is language itself, the medium through which all these illusions are transmitted. It is the stage, the scenery, and the unreliable narrator. My Language Insufficiency Hypothesis proposes that language is not simply a flawed tool — it is fundamentally unfit for the task it pretends to perform. It was forged in the furnace of survival, not truth. We are asking a fork to play the violin.

This insufficiency is not an error to be corrected by better definitions or clever metaphors. It is the architecture of the system. To speak is to abstract. To abstract is to exclude. To exclude is to falsify. Every time we speak of a thing, we lose the thing itself. Language functions best not as a window to the real but as a veil — translucent, patterned, and perpetually in the way.

So what, then, are our Truths™? They are narratives that have won. Stories that survived the epistemic hunger games. They are rendered authoritative not by accuracy, but by resonance — psychological, cultural, institutional. A “truth” is what is widely accepted, not because it is right, but because it is rhetorically unassailable — for now.

This is the dirty secret of epistemology: coherence masquerades as correspondence. If enough concepts link arms convincingly, we grant them status. Not because they touch reality, but because they echo each other convincingly in our linguistic theatre.

Libet’s experiment, Foucault’s genealogies, McGilchrist’s hemispheric metaphors — each peels back the curtain in its own way. Libet shows that agency might be a post-hoc illusion. Foucault reveals that disciplines don’t describe the subject; they produce it. McGilchrist laments that the Emissary now rules the Master, and the world is flatter for it.

But all of them — and all of us — are trapped in the same game: the tyranny of the signifier. We speak not to uncover truth, but to make truth-sounding noises. And the tragedy is, we often convince ourselves.

So no, we cannot escape the prison of language. But we can acknowledge its bars. And maybe, just maybe, we can rattle them loudly enough that others hear the clank.

Until then, we continue — philosophers, scientists, diagnosticians, rhetoricians — playing epistemology like a parlour game with rigged dice, congratulating each other on how well the rules make sense.

And why wouldn’t they? We wrote them.
