'The smell of dust and damp stone will always cry “safety!”'

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.

Giving voice to those on the edge

A nervy, precarious read echoes the lives of outsiders across Europe. Simon Burton-Jones reviews Ben Judah’s This is Europe.

Nino, from Georgia, embraces her grandchildren after their mother's death.

Ben Judah.

In The Dream of Europe, Dutch historian Geert Mak takes on the continent’s twenty-first century story.

There’s something contradictory, he says, about writing the history of an era when you’re right in the middle of it, of a world in which you’re fully involved.

His attempt to do this is built round three great socio-economic tremors: the global financial crash of 2008, the ensuing Greek debt crisis of 2009 and following years and the migrant emergency of 2015. It is a long, involved work.

Ben Judah has tried something very different in This is Europe (Picador, 2023). Adopting the style of his award-winning This is London, he tells the continent’s story via twenty-three disparate individuals. From Turks to Spaniards, Georgians to Swedes and Poles to Serbs, if there is one thing shared most in common, it’s the sense of outsiders trying to make their way from the edge of life to a place of security, even belonging.

History is having its makeover in the attention given to ordinary, prosaic, unseen lives that are lived in the shadow of bigger themes. Judah is not alone and not the first to deliver this, but it is a welcome departure from the grand sweeping narratives and ideologies by which the story of Europe has customarily been told.

He begins with a Dutch harbour pilot, Jelle, who boards and guides container ships into port. It is Europe’s consumer gateway. Jelle observes: ‘What rubbish is actually in these containers?’ It’s toys. TVs. Chairs. Tables. Bicycles. Shampoo. Only rubbish.

But the commentary on Europe’s excesses ends there and there is no logical progression in the book from seaport to city centre. Judah instead jumps from one location to another and tells each individual story in a staccato delivery that lends a sense of immediacy and urgency to their lives. It makes for a nervy, precarious read.

There is the resentful Romanian lorry driver whose account lifts the lid on the sordid risks long-distance jobs supply. The Latvian teenage girl who slips into online sex work, satisfying the fantasies of older men across the world but paying for her education along the way. The thoughtful Belarussian family that defies President Lukashenko and pays a heavy price. A young Turkish woman whose romance with an Austrian boy seems doomed to failure until the final moments. The Russian gas worker whose stint in the Arctic circle has a hint of the Gulag about it. A sex-obsessed Syrian refugee who makes it in the world of porn.

This latter case of the Arab porn star is indicative of Ben Judah’s journalistic style. The seemingly soulless promiscuity and infidelity carries no authorial judgment. Ibrahim escapes the war-ravaged Middle East, is subject to racist humiliation, has sex with anyone who is up for it and is about to be made homeless when he finds a way into an online Arab market in porn. It is part American dream and part pulp fiction set against the backdrop of conservative family Budapest. We are left wondering what to make of it, which is probably Judah’s intention.

Geert Mak speaks of Europe as a great project by free citizens who tried to take the course of history into their own hands instead of merely submitting to it; projects with their origins in the Enlightenment ideals of human rights, liberty, equality and fraternity.

Mak’s dreamy aspiration has just enough about it to attract outsiders but its values when probed are as malleable as playdoh. When pressure is applied, is it possible to say that Europe has cohesive and durable moral values, ones derived from its history? The liberal individualism drawn from the left, where identity has become more distinctive than class, is suspicious of religion that creates hard boundaries, and of objective moral values that constrain behaviour. The right, whose neo-liberal market forces have corroded the very family structures it claims to support, is wary of religion that champions diverse communities. The impact of the left and of the right in these ways is felt in the personal stories of Judah’s book. As unseen forces draw people to poles like filings to magnets, is there a way of transforming these emphases?

There is a relational view of life, perhaps buried deeply in the European Christian Democratic tradition, that values the person in community and the quality of our relationships at every level over ever-expanding GDP, that sacred cow of post-war politics. Where unity and diversity can be held in a creative partnership as we respond to the call to love others as we love ourselves. But it needs clear policy edges that rescue it from pious bromide.

In This is Europe we meet people who are deeply human and equally scarred, often by other people and the forces over which no-one seems to have control, who find their hope and meaning in the relationships they form and through which they make community. Further to the east, Belarussian author Svetlana Alexievich has spent a lifetime teasing out ordinary stories of the Soviet Union, from the veterans of Afghanistan to the victims of Chernobyl via the trauma of the nineties. Hers is a more discursive tale than Judah’s but carries the same sense of disorientation, loss and stoic hope.

Europe cannot be summed up, but Judah, in turning to its edges and listening patiently and empathetically to those who only want to make their way against the odds, inhabits the ethic of scripture in giving a voice to the voiceless. If its stripped back, breathless style carries echoes of Mark’s Gospel, the attention he gives to those in existential pain is St John’s. He calls them each by name. The moral question facing Europe is whether we really want to know their stories.
