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.

Humility is just plain weird

Can leaders be humble?

Graham is the Director of the Centre for Cultural Witness and a former Bishop of Kensington.

Last week I met the Pope. You don’t often get to write a sentence like that but despite the shameless name-dropping, I mention it because it got me thinking about something that shed light on our political and social life.  

It wasn’t just me and him. I was with a group of Anglican bishops and Archbishops and we had an hour with Pope Francis in one of the grand reception rooms in the Vatican. When you enter the Vatican, you can’t but be impressed by the sheer grandeur and size of the place. Long corridors with statues and huge windows, large reception rooms with elaborate frescoes of biblical scenes, Swiss guards with their brightly coloured uniforms saluting as you walk past.  

The grandeur is perhaps not surprising, and perhaps even modest for an institution that that has 1.4 billion followers – that’s about the population of China – and one of the greatest patrons of the arts in western history.  

We filed into a long elaborately painted room with marble floor, and decorated ceiling, took our seats and waited. Finally, a frail, white-robed figure hobbled in, aided by attendants in suits and white bowties. Pope Francis was a bit unsteady on his legs, but sharp, mentally alert, and with a smile that broke out over his face from time to time. 

If the Vatican felt like the palace of an ancient city state, the headquarters of a global network, like the Kremlin or the headquarters of Google, something else felt very different. The difference was brought to mind by a picture I saw a few weeks ago. 

... but Keir Starmer or Donald Trump kissing blistered, calloused, guilty feet? Hardly. This was a display of humility that stood out as plainly weird. 

Just before Easter, the Pope went to prison. In case you are wondering how you missed this extraordinary story, it wasn't of course that he had been convicted of some terrible crime, but on this occasion, he went to visit the Rebibbia prison in Rome. While there, the 87-year-old, increasingly frail pontiff, stepped out of his wheelchair, and bent down to wash the bare feet of twelve women prisoners, many of whom were in tears as he did so. There is an extraordinary picture of him with his eyes closed, kissing the right foot of one of the women, clothed in her grey prison tracksuit trousers, as if it was him who had the privilege in the encounter and not her.  

When I saw this picture, it struck me how truly extraordinary this action was.  Here is the leader of the world’s 1.4 billion Catholics, performing an act of such staggering…. well, meekness, is the only word I can find for it - kissing the sweaty feet of criminal women, feet that had presumably led them into decidedly questionable places in the past, while doing so not reluctantly but gladly, thinking this was the most wonderful thing he could ever do.  

I tried to imagine other world leaders - the American President, the UK's Prime Minister, the leader of the European Union, the President of China, or the CEO of Google doing something similar. And couldn't. I could imagine politicians visiting a homeless centre to dole out food for the social media coverage, but Keir Starmer or Donald Trump kissing blistered, calloused, guilty feet? Hardly. This was a display of humility that stood out as plainly weird.  

If I had been the Creator of all that exists, I would have made sure that the credit went where it deserved. Yet the world around us has precious few explicit reminders of God.

Yet was not entirely surprising, because humility is a distinctly Christian virtue. The Greeks were decidedly lukewarm about it. Aristotle wrote: “With regard to honour and dishonour the mean is proper pride, the excess is known as a sort of ‘empty vanity’, and the deficiency is undue humility…” Humility was appropriate for slaves but not for noble-born people, certainly not for political leaders, leaders of multinational giants – or popes for that matter.  

Yet Christians have always valued humility. One of the New Testament writers says: “Clothe yourselves with humility toward one another, because, God opposes the proud but shows favour to the humble.” So why does God show favour to the humble? 

The answer is, I think, surprising. It is not that God is majestic and demands humility from us measly creatures. It is that, in the Christian understanding, God is humble. Even though he appears to have not that much to be humble about. If the phrase that captures the understanding of Allah in Islam is ‘God is Great’, the main claim of Christianity is that ’God is Love’. And love cannot be proud or arrogant. It has to be humble. 

The God Christians believe in doesn’t draw attention to himself, and doesn’t shout about his own qualities. Instead, he leaves it to others to do that for him. That fits with the way the world is made. If I had been the Creator of all that exists, I would have made sure that the credit went where it deserved. Yet the world around us has precious few explicit reminders of God. There is no signature written in the sky, billboards or flashing neon lights saying ‘Made by God, just for YOU!’. In fact it is quite possible to go through life and completely miss God altogether.  

If there is a God, he seems oddly reticent, unwilling to advertise his existence, or as the prophet Isaiah put it, perhaps in a moment of frustration many centuries ago, “Truly, you are a God who hides himself.” This theme, of the ‘hidden God’ has fascinated theologians and philosophers from St Paul to Martin Luther, from Blaise Pascal to Søren Kierkegaard.  

Even when God does reveal himself, in the arrival on the human scene of Jesus Christ, even then he is oddly hidden. Jesus was perplexingly reluctant to identify himself as God. He didn’t by and large go around saying “Look at me, I am divine!” It was possible to meet Jesus of Nazareth face to face and go away thinking he was just another Jewish rabbi or teacher. In fact, he was more likely to be found acting out the role of a servant, washing the feet of his friends, providing them with food, living a wandering homeless existence, dying on a criminal’s cross, than doing important things like wearing robes, exerting political power or living in palaces.  Nowhere does God appear to us unmistakably. He is not an in-your-face kind of God. He seems, odd though it is to say it, quite shy. Or perhaps the best word is simply: humble.   

So what the Pope did in that Italian prison may have been unlike any other ruler. Yet on another level it was just like the ultimate ruler of all things.
