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.

I’m not sure Christopher Nolan has actually read The Odyssey

The director has drunk the Kool-aid of modernity, and done so deeply
the head of a classical statue looks up amid embers around it.

Greek myths are full of hubris. Full of it. I feel like ‘hubris’ isn’t a word you hear very often anymore. It means excessive pride or self-confidence that leads to a downfall, in case you were wondering. “Boris Johnson’s hubristic underestimation of the effects of ‘Partygate’ was the final nail in his political coffin,” we might say.  

In one myth, Icarus is imprisoned, but given wings held together by wax in aid of his escape. He is warned not to fly too close to the sun, because the heat will melt the wax. Guess what he does? Yep! Flies too close to the sun. The wings melt and he falls to his death. Hubris

Another myth tells the story of Prometheus. No, not the slightly underrated Alien prequel. (That’s right, I said underrated, but that’s another article for another day). Prometheus defies the Greek gods by stealing fire and giving it to humans. As punishment, Zeus ties Prometheus to a rock and has an eagle eat his liver, only for it to grow back overnight so the eagle can come back the next day and start again. Hubris. 

Greek myths are full of hubris. Full of it. 

And so, this is why I find the new poster for Christopher Nolan’s upcoming adaptation of Greek epic The Odyssey so … bizarre. But then I’ve been nervous about Nolan’s adaptation since it was announced. Nolan is a wonderful filmmaker, but he’s also deeply naturalistic in the messages he conveys. By this, I mean that all his films suggest that nature – the physical, material world of atoms and things – is all there is. Even when he has opportunity to explore themes of the mystical, or magical, or the supernatural, he only does so when a purely ‘natural’ explanation for such things is possible.  

For example, in The Prestige (and HUGE spoilers for the film here: it’s incredible, please watch it if you haven’t), Nolan tells the story of two rival magicians, played by Hugh Jackman and Christian Bale. Robert Angier (Jackman) is trying to work out Alfred Borden’s (Bale) teleportation trick. The secret? (Seriously: big, big spoilers here). Science. Nikola Tesla has invented a device that can clone someone but send the clone to a different location. The trick – the mysterious MacGuffin at the film’s heart – has a natural, scientific explanation. Magic isn’t real and you’re a fool if you think otherwise. 

Perhaps this is also why Nolan directed the wonderful Dark Knight trilogy. After all, Batman’s superpower is just wealth: it’s entirely naturalistic, with nothing that can’t fit into a scientific way of understanding the world. Or we could point towards the science fiction that underwrites Inception, Interstellar, and Tenet. For a filmmaker so gifted at tension and intrigue, he has surprisingly little truck with mystique, mystery, and the divine. But this is a problem when it comes to The Odyssey. A huge problem.  

Let’s return to that poster I mentioned earlier. It shows the head of a classical Greek statue, flames ember underneath it. The caption? Defy the Gods. And it’s at this point I start to wonder if Nolan has actually read The Odyssey. Because The Odyssey takes questions of divinity and their authority very, very seriously. Like many Greek myths and poems, the message of The Odyssey isn’t ‘defy the Gods’. No: it’s ‘trying to defy the gods is an unbelievably stupid, futile, and dangerous thing to do’. Nolan would seemingly have us raze Mount Olympus to the ground.  

Look, all we have is a poster so far. Nolan might prove me wrong. But we shouldn’t be surprised if Nolan reworks The Odyssey in such a way that ‘defy the Gods’ becomes its central message. Because Nolan is a quintessentially modern filmmaker.  

In a 1965 book called Freud and Philosophy, French philosopher Paul Ricœur described the modern period as dominated by a climate of suspicion or scepticism. Within this ‘climate of thought’, the straightforward understandings of things are actually deceptive, instead hiding hidden, deeper, and ‘truer’ meanings. He described Sigmund Freud, Friedrich Nietzsche, and Karl Mark as the ‘masters of suspicion.’ And so the world around us is to be approached suspiciously, to uncover the ‘truer’ meanings about our subconscious (so Freud), our false, religiously imposed morals (so Nietzsche), or our exploitative economic systems (so Marx). 

Each of Ricœur’s ‘masters of suspicion’ might be mapped on to one of the villains in Nolan’s Dark Knight trilogy. Liam Neeson is Ra’s al Ghul, a Freud-like figure who helps Bruce Wayne navigate the psychological effects of his parents’ murders in childhood. Heath Ledger’s mesmeric Joker is Nietzsche’s stand-in, exposing our misguided systems and structures of ethics, tethered to a religious framework we no longer hold to. Tom Hardy’s Bane is Marx, freeing Gotham’s proletariat from the economic structures that oppress them so. 

It's not a perfect fit, but I think there’s more than enough evidence to say that Nolan has drunk the Kool-aid of modernity, and he has drunk so very deeply. And this would be fine – absolutely fine – if he wasn’t planning to adapt The Odyssey. Because, as a quintessentially modern filmmaker, Nolan’s work emerges out of and celebrates a culture wherein ‘defy the gods’ is a slogan that can only be heard as heroic, courageous, and noble, rather than dumb and futile, as The Odyssey would stress to us. 

Defying divinity is not heroic. The Odyssey knows this and knows it well. Defying the gods never ends well for humans stupid enough to try in Homer’s work. Our modern sensibilities encourage us to be suspicious of institutionalised power, especially when that power takes a religious shape. We are predisposed to imagine that invocations of the divine are nothing more than thinly-veiled power-grabs. And sometimes they are. But The Odyssey is right to say that divinity itself is not to be trifled with. Renounce your creator at your peril. 

Like all his other films, Nolan’s The Odyssey is likely to be tense, wrought, and cinematographically immaculate. But also like his other films, I worry it will be deeply naturalistic in the way it handles the inescapably divine and supernatural elements present in Homer’s epic. The Odyssey has an important message for our increasingly hubristic society. I just worry that Nolan’s not the man to convey it as it deserves.
