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.

'The smell of dust and damp stone will always cry “safety!”'

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.

Why a book? The words that change the world and me

Living by a literature that’s imbibed in countless cultures.

I have a belief system, a story that I live by, a lens through which I perceive the world. That doesn’t make me unusual or in any way different to you – we all have those, whether we’re aware of them or not. What may make me different to you is that mine are primarily explained to me through a book – or, more accurately, a library of sixty-six books – which we call the Bible.

The story that I live by, that I breathe in and out, is bound. It sits within a cover, it moves through pages, it unfolds according to a contents page – it has genre, it has authors, it has punctuation.

And I’ve never really found this odd.

I think it’s because I’m what Charles Taylor would call a ‘storied creature’, my default is to make sense of the world on a largely imaginative level. I’m also quite romantic; poetically inclined, one could say. It sometimes feels as though words flow through my veins – if you were to cut me open, I may just bleed a puddle of my favourite Jane Austen monologues straight onto the floor. And so, my personality happens to lend itself spectacularly well to living my life according to a spiritual, sixty-six book wide, library. I’ve never really had to wrestle with the strangeness of such a thing, I’ve never sat down and stared the oddness of it in the eye, I’ve never even really asked myself (or God): why a book?

I feel I should pause here, and offer a quick Rory Stewart-esque explainer, just so that we’re all on the same page.

What I, and Christians through time and place, call the Bible is an anthology of sixty-six books, written by around forty authors, in three languages, over the span of 1,400-ish years. Within it, one can find poetry, narrative, apocalyptic literature, erotic literature, lists and figures, instructions and explanations. It is – year in and year out – the bestselling book in the world, with over 100 million copies sold or gifted each year. The New York Times Bestseller List actually omits it from its rundown, because otherwise it would always be so boringly there – sitting comfortably right at the top. No other book ever comes close. Words from this anthology of literature are graven into the floors and walls of the Houses of Parliament, they’re woven into almost every work of Shakespeare, they’re spray-painted clumsily onto billboards in the city I call home.

And so, I guess, in one way, the answer to my question – why a book? – is all of that. The peculiar far-reaching resonance of the methodology speaks for itself. I think of Robin Williams’ impassioned monologue in Dead Poets Society…

‘No matter what anybody tells you, words and ideas can change the world. We don't read and write poetry because it's cute. We read and write poetry because we are members of the human race. And the human race is filled with passion.’

… And I get it. I understand why it was literature that was compiled, why language and words were the tool of choice. For better and for worse, biblical words and ideas have changed the world – they have been ‘the making of the western mind’, just ask Tom Holland. And so, pragmatically, one could argue that the Bible being a book (or a book of books) means that it has successfully imbedded itself in countless cultures, while also transcending them. It’s gone further, lasted longer, sunk deeper than any other form of communication could. Such is the power of words.

But to stop my pondering there feels like I’d be stopping short. I’m not sure that a distant, pragmatic, academic answer is one that I feel satisfied with.

So, this morning, I sat down with a cup of tea, a pen, my notebook, and a newfound curiosity - and I asked myself, and God, why a book?

Why poetry?

Why story?

Why wordplay?

Why have I – an educated, arguably disenchanted, most definitely left-brained, twenty-first century adult - been so willing to let these things mould my interior life? Why am I so moved by them? Moved to action, moved to tears, moved to rage. How can I read something that was written a millennia ago, in a part of the world I have never trod on, and somehow feel as if it is a love letter written exclusively to my own soul?

I think that those are the real questions - the questions to which I have both a thousand and zero answers.

And, like any work of literature, it does not give its meaning up easily – it requires me to sit with it, to excavate it, to gnaw on it like a dog with a bone.

Zero answers, because I fundamentally think that it’s a spiritual thing, a God-designed thing, a thing that sits beyond any explanation I could piece together. The God that I believe exists wants me to know about him, wants me to learn and study, wants me to get glimpses of how thinks, how he works, he feels about me – and you. That’s a wild and wonderous thing. That reality leads me be stunned not only at the methodology, but the desire behind it, as St. Augustine wrote,

‘the whole Bible does nothing but tell of God’s love’.

And so, this literature, to me, is a source of truth, leaning into Iain McGilchrist’s inkling that,

‘the fact that religions and mystical and spiritual traditions have always had to use language in a poetic way doesn’t mean that what they’re talking about is not real, it means it is ultimately real.’

The biblical literature uses words to take us to the edge of them.

And, like any work of literature, it does not give its meaning up easily – it requires me to sit with it, to excavate it, to gnaw on it like a dog with a bone.

Sometimes reading it feels like a balm on my heart, other times it feels like a wrestle in the dirt. But I guess that’s the beauty of it being a book, right? My worldview sits within a piece of literature that is adorned with my scribbles, tear stains, tea spills. A book that meets me every single day, ready to read me as I read it, giving my as many questions as it does answers.

So, why a book? Because now that I think about it, it is odd. The powerful resonance of words for all cultures at all times, perhaps? Or the way that poetry was designed to make a bee line for the deepest parts of us? Or the fact that it is only through language that we can talk about the things that go beyond it?

There are a thousand human-sized answers, if you really need them. I happen to enjoy the mystically-charged zero answers, myself.
