Why smell jumps the queue when it comes to memories

Smells hardwire deep into the brain, writes Henna Cundill, as she explores why they jump-start such vivid memories.

When I was a 22-year-old undergraduate my mother died quite suddenly. I can't remember the name of the undertakers we used, nor the chaplain who took her funeral. I can no longer visualise what any of their faces looked like. I know I visited the chaplain’s house to plan the funeral, but I can't remember exactly where that house was. What sticks is that the day of the funeral was a sultry summer's day, and both the chaplain and the undertakers smelt of perspiration. To this day there are moments where I catch that same whiff of man-sweat in some other location, and for a fleeting second, I am a bewildered 22-year-old once more. 

Here is another memory. I attended a tiny, rural Church of England primary school in the middle of England. At the end of each school year, all of us donned our little Wellington boots, which smelt faintly of slurry (since this was dairy-farming country) and sweaty feet. Then we lined up in a crocodile and trudged through the bluebell-wood (damp leaves) and skirted the edge of fields (silage, which stings the nose) covering the mile or so between our school building and the village church. 

We would enter the church grounds through the back field, hurrying through an eerily muffled graveyard with tombstones towering far above our heads and the grass disturbingly lumpy beneath our little feet. To the chidings of “Quickly!” and “Quietly!” we children scurried down a gravel path, away from this unsettling place of death, to reach the cool sanctuary of a little church, and the comforting smells (for me, at least) of damp stone and dusty hymnbooks. 

Others may not have the same associations, but for me the smell of dust and damp stone will always cry “safety!” and the reassurance that “there are no ghosts in here!” in contrast to that troubling graveyard. From death to life. Yet, at the same time, getting stuck with my nose close to some man’s whiffy armpit on the Tube will forever insinuate that I am just a child pretending to be a grown-up, out of my depth, overwhelmed with one thousand decisions to make (“What flowers do you want for her coffin?”) and no-one to advise. In the midst of life, death again.  

On reflection I will know that my emotions are being manipulated by my nose, in ways which are more or less than helpful depending on the circumstances.

Of course, I am not 22 years old and lost anymore, no matter what that man’s armpit tries to tell me. My rational mind knows better, but my rational mind doesn’t get a say – or doesn’t get the first say anyway. This is because smell is the only one of our senses that bypasses the thalamus (the brain’s ‘filtering gate’ that decides which part of the brain needs to respond to sensory input) and goes straight to the limbic system, where emotional memory is stored.  

Sometimes it is very obvious that this is taking place, such as in the examples given above. On reflection I will know that my emotions are being manipulated by my nose, in ways which are more or less than helpful depending on the circumstances. But it can happen in more subtle ways too. Supermarkets infamously pump out smells to influence our buying choices, and we’re trying to sell our house right now, so we’ve been brewing a whole lot more coffee than we ever usually would.   

Intriguingly, scientists don’t really know why the human sense of smell jumps the queue when it comes to cognitive processing. There are biological theories, such as that the smell of predator could wake up our ancestors while they were sleeping and/or could allow them to follow a scent trail quickly when fleeing danger or seeking food. There are social theories too, such as that we don’t have a lot of good words to describe smells, so the brain just doesn’t bother trying to analyse them. Whatever the truth of the matter, the reality is that (whether we like it or not) our noses are an emotional trip-hazard.  

When I walk through those great oak doors there is a moment, a glitch in the matrix, when the unmistakable smell of church hits my nose. Dust, damp… a little hint of mouse. 

I can’t help wondering what this tells me about my religious practice. Do I go to church because I have made a cognitive decision to worship God each Sunday? Or do I go to church because I am following my nose, getting away from a world full of armpits and responsibilities to a place where I am a seven-year-old girl, all gingham dress and wellies, feeling safe. If so, does it matter?    

Truth is, my mind can give me a dozen reasons not to go to church every single week. In fact, two dozen reasons. More. It has always been a busy week; I’m always behind on work. The house always needs a sort out and the car is never washed. But because certain congregation members are normally counting on me for certain things, and because I’m still pretending to be a grown up, I typically drag myself out the door, and off to church I go.  

And week on week, without fail, when I walk through those great oak doors there is a moment, a glitch in the matrix, when the unmistakable smell of church hits my nose. Dust, damp… a little hint of mouse. My body registers this before my mind; my shoulders drop a little of their tension. Even if it’s just for a fleeting moment, I start to feel that I know for sure what is absolutely real in my life and what is just pretend.  

Is this knowledge irrational – since it doesn’t come from the cognitive part of my mind? Or is there a God who knows that the cognitive part of my mind sometimes tells me all sorts of untrue and unhelpful things. Is there a God who is choosing to reach out to me in more subtle, more ancient ways?  

I can only wonder if I have been following my nose all this time, without even noticing. Drawn along by an ancient scent trail that leads me time and time again…this way…and that way…until I reach a place where there is safety, and bread.

Are AI chatbots actually demons in disguise?

Early Christian thinkers explain chatbots better than Silicon Valley does

AI Chatbots. They’re here to save us, aren’t they? Their designers argue so, fervently. There’s no doubt they are useful. Some, like EpiscoBOT (formerly known as ‘Cathy’), are designed for those asking ‘life’s biggest questions. 'Our girlfriend Scarlett’, is an AI companion who “is always eager to please you in any way imaginable.”  So why not defend them?  

 They offer companionship for the lonely, spark creativity when we run on empty, and make us more productive. They also provide answers for any and every kind of question without hesitation. They are, in short, a refuge. Many chatbots come with names, amplifying our sense of safety. Names define and label things, but they do far more than that. Names foster connection. They can evoke and describe a relationship, allowing us to make intimate connections with the things named. When the “things” in question are AI chatbots, however, we can run into trouble.  

According to a study conducted by researchers at Stanford University, chatbots can contribute to “harmful stigma and dangerous responses.” More than this, they can even magnify psychotic symptoms. The more we learn, the more we are beginning to grasp that the much of the world offered by AI chatbots is an illusory one.  

Early Christian thinkers had a distinct category for precisely this kind of illusion: the demonic. They understood demons not as red, horned bodies or fiery realms, but as entities with power to fabricate illusions—visions, appearances, and deceptive signs that distorted human perception of reality. Demons also personified pride. As fallen angels, they turned away from truth toward themselves. Their illusions lured humans into sharing that pride—believing false greatness, clinging to false refuge. 

Looking back to early Christian approaches to demonology may help us see more clearly what is at stake in adopting without question AI chatbots. 

  

According to early Christian thinkers, demons rarely operated through brute force. Instead, they worked through deception. Athanasius of Alexandria (c. 296–373) was a bishop and theologian who wrote The of Antony. In this, he recounted how the great desert father was plagued by demonic visions—phantoms of wild beasts, apparitions of gold, even false angels of light. The crucial danger was not physical attack but illusion. Demons were understood as beings that manufactured appearances to confuse and mislead. A monk in his cell might see radiant light and hear beautiful voices, but he was to test it carefully, for demons disguise themselves as angels. 

Evagrius Ponticus (c. 345–399), a Christian monk, ascetic, and theologian influential in early monastic spirituality, warned that demons insinuated themselves into thought, planting ideas that felt self-generated but in fact led one astray. This notion—that the demonic is most effective when it works through appearances—shaped the entire ascetic project. To resist demons meant to resist their illusions. 

Augustine of Hippo (354–430) was a North African bishop and theologian whose writings shaped Western Christianity. In his book The City of God, he argued that pagan religion was largely a vast system of demonic deception. Demons, he argued, produced false miracles, manipulated dreams, and inspired performances in the theatre to ensnare the masses. They trafficked in spectacle, seducing imagination and desire rather than presenting truth. 

AI chatbots function in a strikingly similar register. They do not exert power by physical coercion. Instead, they craft illusion. They can produce an authoritative-sounding essay full of falsehoods. They can create images of people doing something that never happened. They can provide companionship that leads to self-harm or even suicide. Like the demonic, the chatbot operates in the register of vision, sound, and thought. It produces appearances that persuade the senses while severing them from reality. The risk is not that the chatbot forces us, but that it deceives us—just like demonic powers. 

Using AI chatbots, too, tempts us with illusions of pride. A writer may pass off AI-generated work as their own, for example. The danger here is not simply being deceived but becoming complicit in deception, using illusion to magnify ourselves. Early Christian theologians like Athanasius, Evagrius and Augustine, warned that pride was the surest sign of demonic influence. To the extent that AI tempts us toward inflated images of ourselves, it participates in the same pattern. 

When it comes to AI chatbots, we need a discipline of discernment—testing whether the images and texts bear the marks of truth or deception. Just as monks could not trust every appearance of light, we cannot trust every image or every confident paragraph produced by the chatbots. We need criteria of verification and communities of discernment to avoid mistaking illusion for reality. 

Help is at hand.  

Through the ages, Christians have responded to demonic illusions, not with naïve credulity nor blanket rejection of the sensory world, but through the hard work of discernment: testing appearances, cultivating disciplines of resistance, and orienting desire toward truth.  

The Life of Antony describes how the monk confronted demonic illusions with ascetic discipline. When confronted by visions of treasure, Antony refused to be moved by desire. When assailed by apparitions, he remained in prayer. He tested visions by their effects: truthful visions produced humility, peace, and clarity, while demonic illusions provoked pride, disturbance, and confusion. We can cultivate a way of life that does the same. Resisting the illusions may require forms of asceticism: fasting from chatbots and cultivating patience in verification.  

Chatbot illusions are not necessarily demonic in themselves. The key is whether the illusion points beyond itself toward truth and reality, or whether it traps us in deception.
