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.

Small Things Like These: putting the spotlight on backstage goodness

What it means for a film to be good.

A ‘stellar’ Cillian Murphy plays Bill Furlong.

Lionsgate.

Small Things Like These is a novella by the Irish writer Claire Keegan. Published in 2021, it compresses a remarkable story into 128 pages. Acclaimed widely by critics and readers, it follows Bill Furlong, a fuel merchant living in the small County Wexford town of New Ross in 1986, as Christmas approaches. While delivering coal to the local convent, Bill makes an alarming discovery. Memories of his childhood begin to press in on him and he finds himself in an existential crisis.

Like her previous (very short) work, Foster, Small Things Like These is an understated book with a searing moral clarity. And just as Foster was adapted for the screen – in the astonishing Irish-language film The Quiet Girl – a movie version of Small Things Like These is now likely showing at a cinema near you.

The movie is built around a stellar performance from Cillian Murphy. It would be criminal if his name is not featured among the shortlists when awards season comes round. Many of the film’s most arresting scenes feature close-ups of his face as Bill wrestles with the implications of his discovery and the phantoms of his past. The effect is that the film serves as an almost literal portrait of what it means to be a decent person.

The story begins with Bill making a delivery to the convent. He sees a mother drop off her screaming daughter to the back door, where she is met and manhandled inside by a nun. The teenager protests passionately, but to no avail. The viewer understands that this girl has “fallen pregnant”, to use the Hiberno-English idiom that was so common in the twentieth century. She has been dispatched by her family to this institution to serve out the months of pregnancy and to remove any shame or taint from their reputation. Bill watches as the girl shouts out for her father, who is entirely absent.

And, after a tense interaction with an aggressive nun, he goes home to his five girls and his wife, clearly shaken.

A few days later, unable to sleep, haunted by memories of his own childhood being raised by a single mother, with an absent father, relying on the kindness of a wealthy local landowner, he begins his deliveries before dawn. As he deposits peat briquettes in the coal shed of the convent, he discovers a teenaged girl abandoned in the corner of the tiny, filthy room. She is in deep distress and Bill responds instinctively, wrapping his coat around her shoulders and bringing her inside to the convent.

While the existence of Magdalene Laundries and Mother and Baby Homes were not a secret in twentieth century Ireland, the exact details of their operations were not widely understood. With these two encounters, so close together, and his own personal biography as the son of a woman who was subject to exactly the same marginalising dynamics, Bill can no longer be satisfied to turn a blind eye to the oppression and alienation endured by those sent for reformation.

It evokes the ways in which all such systems of oppression are socially constructed and maintained. Otherwise, good people learn to look the other way.

The film gathers momentum as Bill is forced to confront the way his mother had been treated for “falling pregnant” and the reality experienced by girls the same age as his daughters who were in a similar situation. In the midst of his existential angst, he finds little solace in the no-nonsense pragmatism of his wife who reminds him “there are things you have to ignore” to get on in life. He is taken aside by his local publican, a woman who has similarly scrabbled up from humble origins to establish a thriving business and cautioned to not make trouble for the nuns since “their fingers are in every pie in the town”.

I will refrain from fully revealing every detail of the film’s plot. But this element of the screenplay – where Claire Keegan along with Enda Walsh – draw out the sense in which the oppressive ecclesial institutions were enabled and even sanctioned by the wider population is exceptionally well done. The film does not pull any punches on the evils that were committed in the name of churches in Ireland. Indeed, if anything, the presentation of the nuns veers too far towards caricatures of pure malevolence. But with surgical precision, it evokes the ways in which all such systems of oppression are socially constructed and maintained. Otherwise, good people learn to look the other way.

And that is the lasting significance of this film. Toni Morrison has spoken about how it can seem harder to write about goodness than evil. “Evil has a blockbuster audience; goodness lurks backstage.” In Small Things Like This, Claire Keegan introduces us to a hardworking small business owner who treats his staff well, a loving father who seeks to care for his wife, a man who lives down a back street of a provincial town in an overlooked part of a small island on the periphery of Europe. And in this very definitively backstage context, he is presented as heroic in his pursuit of the Good.

We all fancy ourselves to be the one person who would stand up and oppose systems of oppression if we ever found ourselves enmeshed in them. Cillian Murphy’s depiction of Bill Furlong whispers to us that we likely are enmeshed in just that way and are choosing not to notice. Small Things Like These is a heavy film that somehow liberates. It reminds us that there is, within each of us, this appetite for seeing the Good and bring brave enough to do it. It is worth your time far more than any competing blockbuster.
