Reason is not an oracle of truth but a spectrum-bound tool, and when it is worshipped as absolute, it curdles into pathology. True rationality knows when to temper itself, when to equivocate, and when a kind lie is wiser than a cold fact.

Reason and rationality are the household gods of modernity. We light incense to them daily: follow the science, be reasonable, act rationally. But before we genuflect, it’s worth asking what exactly we mean. By reason, I mean the faculty of inference – spotting contradictions, tracing causes. By rationality, I mean the practice of applying that faculty toward some end. That’s all. Nothing mystical.

The trouble starts when these concepts are treated as absolutes. They aren’t. They vary in intensity and application. A person’s reasoning operates on a spectrum with something like frequency and amplitude. Some minds hum at low frequency – broad strokes, contradictions smoothed over by intuition. Others burn hot at high frequency and amplitude – rapid logical leaps, obsessive consistency, the inability to let a premise go. And while some reason flows like a continuous wave – steady, consistent, predictable – other forms fire more like particles: synaptic sparks that don’t always connect, logic arriving in bursts or stutters rather than as a smooth line.

“But a normal ego of this sort is, like normality in general, an ideal fiction. The abnormal ego, which is unserviceable for our purposes, is unfortunately no fiction. Every normal person, in fact, is only normal on the average. His ego approximates to that of the psychotic in some part or other and to a greater or lesser extent; and the degree of its remoteness from one end of the series and of its proximity to the other will furnish us with a provisional measure of what we have so indefinitely termed an ‘alteration of the ego’.”

― Sigmund Freud

Push too far and what we sanctify as ‘reason’ bleeds into what psychiatry pathologises as autism or schizophrenia. Meanwhile, ‘normal’ cognition always includes an emotional ballast. Strip it out and the result looks alien, even monstrous. Freud’s quip about psychopathy – that the psychopath differs from the rest of us in degree, not kind – applies just as well to reason. Rationality is simply the socially acceptable blend of logic and affect. Deviate, and you’re declared broken.

Camus gave us a parable in The Stranger. Meursault observes his world with ruthless clarity, but no emotional resonance. He doesn’t weep at his mother’s funeral, and society condemns him less for murder than for failing to perform grief. His ‘pure’ reason reads as inhuman.

Here’s the paradox: if rationality means adapting effectively to one’s environment, then pure rationality demands knowing when to suspend itself. A person who insists on logic at every turn is not rational but maladapted. The rational actor lies, flatters, nods at the boss’s bad joke, comforts the friend who doesn’t want statistics but solace. Rationality that cannot bend collapses into pathology.

This is why the infamous ‘Do these jeans make me look fat?’ question is such a perfect test. The ‘true’ answer, if you are reasoning narrowly, may be ‘yes’. But true rationality recognises the context, the stakes, the human need beneath the words. The rational response is not the cold fact but the kind equivocation. Rationality that cannot lie is no rationality at all.

Consider the social rituals we all know. A partner says, ‘I like that house’, and the rationally over-tuned response is to evaluate the house. The actual cue is in the like, not the house. The answer isn’t that you dislike the house, but rather what you can appreciate about it. Miss that, and you miss the point. Or take the dinner table: when my son was seven, a well-meaning host – very Martha Stewart – asked him how he enjoyed his meal. He replied, with perfect candour, ‘I’ve had better’. From a logical standpoint, faultless. From a rational standpoint – if rationality includes social adaptation – disastrous. The question was never about the food. It was a cue for appreciation, for harmony. He gave fact when what was asked for was affiliation.

So yes, I attack reason and rationality – not because they don’t exist, but because they are misapplied, reified, and worshipped as neutral arbiters of truth. They are not. They are tools with a range, and outside that range, they fail catastrophically. To speak of ‘reason’ as if it were an unqualified good is like praising fire without mentioning its talent for arson.

After I wrote this, I realised I forgot to mention Kant.

Even Kant, patron saint of rational duty, insisted you must never lie, not even a white lie, not even to a murderer asking where your friend is hiding. For him, truth-telling was categorical, binding, immune to circumstance. But this is reason gone rigid, unable to flex with human reality. It shows how worship of Reason leads not to morality but to monstrosity. A rationality that cannot bend is no rationality at all.
