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.

What we lose when we AI tempts us to refuse our limits

Geoffrey Hinton, the so-called “godfather of AI,” was recently asked by a Financial Times journalist to consider a future in which human beings live among robots and gradually morph into cyborgs, their lives prolonged by artificial parts and chemical enhancements. His reply was strikingly casual: “What’s wrong with that?” Thankfully, his answer reflects a minority view today, but one that will grow significantly in both plausibility and appeal as the culture of Silicon Valley – animated by transhumanist ambitions and backed by enormous capital and influence – seeps into the ‘social imaginary’ of the West.  

In an individualist culture of ‘quantified selves,’ where self-optimization and wellbeing dominate the horizon of desire, it will take little to sell such enhancements, which will be promoted as not merely the means of surviving ‘rogue AIs’ but the way to flourishing. 

But this represents a profound distortion of what flourishing has meant across centuries of philosophical and theological reflection: the actualization of our true nature through the practice of virtue (Aristotle) and living in alignment with our proper end (telos), which is communion with God (Aquinas). Once tethered to a moral and spiritual vision of the human person, flourishing is fast becoming a runaway concept, thinned out on the anvil of individualism and moral autonomy, and conflated with the promise of expanding ad infinitum one’s capacities, choices, and life itself. It is precisely this  hyperindividualist vision that OpenAI CEO Sam Altman has in mind when he speaks of his mission of enabling ‘maximal human flourishing’.  

But the ethical and anthropological crisis we are entering cannot be resolved by neuroscience, secular anthropologies, let alone economics alone, but only through engaging with Christian anthropology. At the heart of the Christian faith stands the claim that Jesus Christ is the archetypal human, the “second Adam,” in St Paul’s phrase. Not simply in the sense that he is a morally and spiritually exemplary figure whose ethical teaching we might want to consider. But, more boldly, in the sense that all human beings - past, present, and future - are mysteriously caught up, redeemed and fulfilled in the person of Christ. In his life, work, death, resurrection and ascension, humans are given the ultimate revelation not only of God, but also of what it means to be truly human and flourish. This means, among other things, that our limitations as creatures are not problems to be overcome but gifts to be honoured, the thresholds where God embraces us in grace. Our dependence and vulnerabilities are not defects to be corrected but the very conditions for fulfilling our humanity, in community, through the practices of faith (trust), hope, and love. 

Of course, there are distortions and privations that disfigure human life – disease, cruelty, injustice – which rightly summon humanity to acts of repair and resistance. As a product of God-given creativity, modern medicine and its many cures to previously fatal diseases is a huge blessing. But as biotechnology and AI continue to advance, the line between therapy and enhancement, healing and augmentation will likely become increasingly blurred. 

Against visions of human nature as infinitely plastic and of human beings as projects of self-invention, the Christian faith offers the liberating message that humanity is created, incorporated and will be fulfilled in Christ. To be human, then, is not to upgrade oneself without end to avoid vulnerability and death, but to be drawn into Christ, who died but was raised to life and glory. It is to find in him, and to practically outwork through His spiritual body, the Church, the measure of true, mutual flourishing, for the sake of the world. Only from this centre can we wisely discern how to receive and harness the gifts of technology without buying into its counterfeit promise of salvation.
