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.

We're pretty useless really

We all fail. Not just Southgate, Biden and Sunak.

George Pitcher

George is a visiting fellow at the London School of Economics and an Anglican priest.

A dejected looking football manager ponders his feet while standing beside a pitch.

Southgate contemplates.

The Book of Heroic Failures, published by Stephen Pile in 1979, records a story of the Welsh Dean of St Asaph, Daniel Price, in the late 17th century. Contemporary biographer John Aubrey noted that Price was a “mighty Pontificall proud man.”

So proud that he declined to parade on foot outside his cathedral, but rather rode a mare in full vestments, reading from the Book of Common Prayer. Aubrey with precise economy describes what happened next: “A stallion happened to break loose, and smelled the mare, and ran and leapt her, and held the reverend dean all the time so hard in his embraces, that he could not get off till the horse had done his business.”

Unsurprisingly, Aubrey records that the good Dean “would never ride in procession afterwards.” He had clearly learned a lesson in humility. And one that would not have been taught had his ride passed with pompous dignity.

A question arises, pertinent for events today, as to whether we learn more from the indignity of failure than from the fruits of success. I’d like to suggest that we do, especially about the nature of our human condition.

Humans are pretty useless really and our default position is error and falling short.

No one doubts that had England won the European Football Championship it would have been the crowning adornment to manager Gareth Southgate’s career. England failed to do that, though we failed less than any other team (Spain doesn’t count because they didn’t fail at all). Now that Southgate has resigned and has time to reflect at leisure, perhaps he will learn at least as much and possibly very much more about himself than if he had raised the trophy.

US president Joe Biden would have had an altogether greater reckoning to face if he lost the election to Donald Trump than if he won it. Now he’s quit the race, arguably he has much more to learn from reflecting on his life and achievements. The Conservative Party has many lessons to learn about its 14 years in power from its abject defeat at the polls. Indeed, many parliamentary Tories believe that defeat was a requisite event for its reformation to proceed.

None of this is to suggest that failure of itself is a virtue. Nor is it just a morality tale that enjoins us to meet triumph and disaster and “treat those two impostors just the same”. A failed marriage, or failing health, or moral failures of a wider variety, cause destructive pain and trauma.

But it is to acknowledge that failure is part of the natural human condition. We’re in the territory of a flawed, fallen humanity here, one that theologians call postlapsarian, that is fallen from an ideal of perfection as dramatically portrayed in the Garden of Eden. Humans are pretty useless really and our default position is error and falling short.

Loss of innocence, injustice and failure meet in unholy alliance at Golgotha.

This isn’t, or should not be, depressing. At least not for people of faith, because it reflects the nature of humanity. Failure, if you will, is a gift of God in a fallen creation. We learn more from our failures than our successes, which is either a biological determinism in evolution or a means through which we strive for a new perfection. There’s a version of that they may be reciting to the England football team right now.

Christian faith sometimes concentrates too often on triumph over death and the idea of a heavenly kingdom where all is well, at the expense of recognising the reality of our world in which most things are very far indeed from well.

We might recognise it in a congregational tendency to skip over Good Friday to Easter morning. If we do so, we neglect to notice what an abject failure the insurgent Jesus movement was on its short journey of break-up from Jerusalem to Calvary. It, literally, dies.

Yes, we know what happens next. Or do we? The first witnesses to it certainly struggle to explain it in a manner that we might comprehend. But, in any event, loss of innocence, injustice and failure meet in unholy alliance at Golgotha.

The theologian John Macquarrie asks what happens if we feel compelled to draw the bottom line under the cross: “Would that destroy the whole fabric of faith in Christ? I do not think so, for the two great distinctive Christian affirmations would remain untouched – God is love, and God is revealed in Jesus Christ. These two affirmations would stand even if there were no mysteries beyond Calvary.”

No, our story doesn’t end there. But we can acknowledge that this is where we live in this world, at the foot of that cross. As the 17th-century French philosopher Blaise Pascal put it, the Christ “will be in agony until the end of the world.”

Let’s not be too miserable, because we do have the “mysteries beyond Calvary”. And let’s celebrate our earthly successes. But let’s also learn to embrace our failures and receive them as a gift, from football to politics.
