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.

My conversation with... Molly Worthen

Belle TIndall is fascinated by the intellectual fascination that drove Molly Worthen’s inquiry into faith.

Can you think your way into Christianity?

Can your mind lead the way into something that transcends understanding?

Is it possible to ‘fake it until you make it’ when it comes to belief in God?

These are the questions that hold our conversation with Molly Worthen together. Molly, for those of you who aren’t yet acquainted with her work, is a journalist and associate professor of American history at the University of North Carolina at Chapel Hill. For the past decade, her intellectual sweet spot has been the religious and intellectual history of North America. Flowing from her fascinating research are books such as Apostles of Reason: The Crisis of Authority in American Evangelicalism, as well as pieces for the New York Times, The Atlantic and The New Yorker.

Intellectual fascination was her gateway into faith. She used homework, deadlines, schedules and challenges as tools with which she worked out and fine-tuned her beliefs.

In this episode of Re-Enchanting, Molly very generously walks us through her own story; from a child who would cover her ears when being read Bible stories, to a young adult who could relish the oddity of religious experience from a distance, to a journalist investigating various Christian communities, to a baptised Christian attending a mega-church. It’s quite the journey, but I shall leave it to Molly to unpack the full story, seen as she tells it with the vigour and detail of a historian.

I find Molly’s story captivating for many reasons, the primary one being that her intellectual fascination was her gateway into faith. She used homework, deadlines, schedules and challenges as tools with which she worked out and fine-tuned her beliefs. She says herself, ‘I needed to process to be rigorous’. How interesting is that?

Reflecting on the conversation that Justin and I had with Molly, I realise that there are three, rather distinct and yet wholly common, misconceptions about faith that she shatters. I don’t think that she was intending to, I’m not even sure that she was aware that she was doing it. But her fascinating crossing from agnostic to Christian has some interesting philosophical by-products.

She asserted that she didn’t want to ‘convert out of cowardice’ nor was she interested in succumbing to ‘a bribe’.

Firstly, the focused methodology with which Molly approached theism in general, and Christianity in particular, simply dispels the notion that a belief in God must render logic and reason redundant. On the contrary, Molly took step after considered step into her new-found set of Christian beliefs. Her story is one of measured assurance, of ‘not being 99.9 per cent’, but being ‘far north of 51 per cent’.

Secondly, Molly challenges the assumption that faith is sought out as a method of opting-out of the harshest parts of reality. That it’s held as some kind of cosmic ‘Get Out of Jail Free’ card – the ‘jail’ being whatever un-graspable, un-controllable, un-bearable aspect of reality sits most heavily upon us. There’s a common notion that religious people have found a coping mechanism, that they’ve institutionalised their denial and spiritualised their escapism. I’ve often found that notion an interesting one, mostly because I wish that it were true. But it doesn’t quite work that way. Believing in an all-seeing, all-knowing, all-loving God does not mean that one can avoid looking directly at suffering, pretend that it isn’t there, or that it somehow doesn’t ultimately matter. On the contrary, it often requires one to look at it, and wrestle with it, for longer. Nick Cave and Sean O’Hagan’s masterful Faith, Hope and Carnage is an ode to a belief system that resides in the midst of Nick Cave’s pain, as opposed to pulling him out of it. Molly, perhaps from all of her years of research, seemed to know this. She asserted that she didn’t want to ‘convert out of cowardice’ nor was she interested in succumbing to ‘a bribe’. Surely you are convinced by now that Molly Worthen is about as fascinating as it gets?

And finally, it was interesting to hear Molly speak of the choices, both micro and macro, that have led her to where she now finds herself. After all, faith is a choice. It reminds me of the philosopher, William James, who proposed that there are certain beliefs that can’t be evidenced until they are believed. For example, you cannot determine whether a chair will hold your weight until you sit on it believing (at least to a reasonable extent) that it can. This is partly (but profoundly) true of God; while one can ponder the empirical evidence for the existence of God for a lifetime, it is often the case that experiential evidence for God is available once you believe it. This doesn’t mean that belief must be a wholly blind choice, that would only negate my first point, but it is a choice. Again, Molly wonderfully encapsulated the tension of this notion in recalling that,

“what was really preventing me from engaging with this evidence is my own commitment to materialism and my own deep epistemological groove. But if I’m willing to suspend that, what happens?... You can walk right up to it and get to the point where you’re still faced with a leap of faith, but it’s no longer a ten-mile leap into the dark, it’s a leap based on a pretty reasonable body of evidence. And it turns out that to reject that leap is itself and act of faith.”

This episode of Re-Enchanting is a personal, and therefore profoundly interesting, one. We speak to Molly, not of how her field of work has been re-enchanted by the mystery and wonder of the Christian story, but how she has. And that makes this episode incredibly worth your time.
