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.

How C.S. Lewis used myth to supercharge storytelling

Great stories allow ideas to be experienced rather than merely thought about.

‘I’m tall, fat, rather bald, red-faced, double-chinned, black-haired, have a deep voice, and wear glasses for reading’. That is how C.S. Lewis described himself to a class of Fifth Grade pupils in Maryland who wrote to him in May 1954. An exhibition this summer at Magdalen College, Oxford, entitled C.S. Lewis: Words and Worlds, includes this letter along with a variety of personal objects, letters, books, manuscripts and audio materials relating to one of its most famous fellows.

As well as answering questions about plot details and forthcoming books in the series, Lewis corrects their view that everything in the Narnia books represents something in our own world. As he notes, that is indeed how Bunyan’s Pilgrim’s Progress works – a reference which may have been lost on his ten-year-old correspondents – but that’s not what Lewis intended in the Narnia stories. Instead, Lewis explains that he set out to write a ‘supposal’ rather than an allegory. He began by asking himself the question: ‘Suppose there were a land like Narnia and that the Son of God, as He became a Man in our world, became a Lion there, what would happen?’

For Lewis, the great value of stories is the way they allow their readers to experience ideas rather than simply think about them. In an essay called ‘Myth Became Fact’ he notes the impossibility of feeling an emotion such as pleasure and simultaneously studying it. But if you aren’t roaring with laughter, how can you genuinely understand humour? If you are suffering from toothache, you will be unable to write. But once the toothache has subsided, how could you write a book about pain? Lewis explains this paradox using the myth of Orpheus and Eurydice. Orpheus was permitted to lead his beloved wife out of the underworld, but the moment he looks back at her, she disappears. We can draw an abstract truth from this story about the impossibility of simultaneously seeing and experiencing, but it is not the only truth that this myth can communicate. If it were, it would be an allegory.

Instead of presenting the reader with a single message needing to be unlocked, myths instil a sense of longing for something much less tangible

As such, an allegory is like a puzzle that must be solved by the reader to reveal its hidden meaning. Its one-dimensional characters straightforwardly signal the qualities they represent, as in Bunyan’s Mr Despondency, held captive in Doubting Castle by a giant called Despair. Unlike allegory, myths are stories from which numerous truths may be abstracted. Instead of presenting the reader with a single message needing to be unlocked, myths instil a sense of longing for something much less tangible – ‘like a flower whose smell reminds you of something you can’t quite place’. Lewis considered allegory to be a limited medium, since authors can only insert ideas that they already know, whereas a myth is of a higher order, since authors can fill it with ideas of which they are not yet conscious.

Lewis was fascinated by myths from his first encounter with the stories of Asgard and the Norse deities as a young man. As an atheist, one of his key objections to the Christian faith was that it was just another version of the myth of a dying god who is resurrected, similar to those he found in the stories of the Norse god Baldr, whose death was brought about by Loki, the trickster god. Following entreaties by Baldr’s mother, the goddess Frigg, Hel agrees to release him from the underworld, on the condition that everything on earth weeps for him. But Baldr’s return is ultimately blocked by one creature, a giantess, presumed to be Loki in disguise, who refuses to mourn him.

Why was Christianity different to this myth, or others, like the Egyptian account of Osiris or the Classical story of Adonis? It was a lengthy night-time conversation with his friends Hugo Dyson and J.R.R. Tolkien in the grounds of Magdalen College in September 1931 that helped him overcome this objection and embrace Christianity. What Lewis came to recognise is that, when he encountered a god dying and being revived in pagan myths, he found it profoundly moving, suggestive of meanings beyond his grasp. But, when he met a similar concept in the Christian gospels, he was unmoved. What he took from his talk with Tolkien and Dyson was an openness to accepting the Christian story as a myth, with all its mystery and suggestive implications, but with one key difference from the Norse, Egyptian and Classical myths: it really happened. But, by becoming fact, he argued, Christianity did not cease to be a myth: ‘that is the miracle’.

Lewis wrote the Narnia stories to help children like Eustace become open to the possibility of a reality beyond the strictly material world.

In writing the Narnia stories Lewis was engaged in what he and Tolkien called ‘mythopoeia’ – the act of myth-making – communicating Christian truths in ways that would inspire children to grasp something of its mystical and mythical qualities. As he noted in his essay ‘On Stories’, reading about enchanted woods does not make children despise real woods, but instead makes all real woods a little bit enchanted. In The Voyage of the Dawn Treader, the children meet Ramandu, a retired star who is being restored to his former youth so that he can rejoin the great dance in the sky. ‘In our world’, says Eustace Scrubb, ‘a star is a huge ball of flaming gas’. ‘Even in your world, my son, that is not what a star is but only what it is made of’, Ramandu retorts. Eustace, we are told at the beginning of the story, had wasted his time at school reading only books of information about exports and imports, so it is no surprise that he can only comprehend a purely materialist definition. If he’d only read more fairy stories, he might have been able to grasp this reality, as well as being better prepared for his adventure on Dragon Island.

Lewis wrote the Narnia stories to help children like Eustace become open to the possibility of a reality beyond the strictly material world. Since God himself is mythopoeic – after all, isn’t the sky itself a myth? – shouldn’t we therefore be mythopathic, that is, receptive to myths? For Lewis, Christianity offered the marriage of Perfect Myth and Perfect Fact, which should be met not solely by love and obedience, but also by wonder and delight.
