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.

Cutting America to the bone

Civil War warns against worshipping civic and political violence.

Civil War's finale in Washington DC.

A24.

The president of the United States is dead. The film Civil War culminates with soldiers of the Western Forces (a fictional secessionist group composed of California and Texas) posing for pictures with a presidential corpse just minutes after executing him. It’s a chilling climax, with optics reminiscent of American soldiers capturing deposed president of Iraq Saddam Hussein in 2003. The film ends with a warning. No democratic country, no matter the perceived strength of its institutions, is immune from tyranny, civil violence, and the bloody process of state failure. Collapse follows when states lose the capacity to provide solutions to the linchpin challenges negatively affecting their citizens.

A strength of Civil War is the way it articulates a universal political message without defiling itself with the toxic hyper-partisanship asphyxiating real-world American society.

It features a number of loyalist and secessionist geopolitical groups each motivated by a distinctive combination of social, economic, and political interests and goals. These groups include the Western Forces, Florida Alliance, New People’s Army, and Loyalist States.

The film’s storyline prioritises a violently unfolding near future civil war in a United States whose president bucked constitutional tradition by remaining in office for a third term. The president, whose character is modelled after Donald Trump, is the villain of the film, despite being supported by over half of the 50 American states. The Western Forces function as the film's hero group. Unlike the mercilessly murderous and viciously xenophobic soldiers affiliated with the Loyalist States, the soldiers of the Western Forces treat an eclectic team of journalists and war photographers (the film’s main protagonists) with kindness and respect, allowing them to accompany them during the final stages of their assault on the White House and entrance into the belly of the beast, the Oval Office.

The film includes shocking scenes that would make the most patriotic Americans shudder. Shortly after it begins, a suicide bomber associated with the Loyalist States, proudly carrying a large American flag, sprints into the centre of a group of vulnerable people, pleading with agents charged with guarding a water tanker, and detonates a bomb. Dozens of people including children are killed, many of whom were non-White Americans. This scene's power is that it bring home the threats Americans associate with foreign lands. Suddenly the menaces Americans instinctively link with states like Afghanistan, Burkina Faso, and Venezuela exist in cities like Charlottesville, New York, and Washington DC. America is no longer safe, and the threats have come from within instead of from abroad.

The message of Christ applies to theocracies and secular states alike. Every state, regardless of its attitudes toward religion, has an interest in its people living together peacefully.

As an American watching this film from a cozy cinema in Oxford, I thought about how the violence, polarisation, and civic rage depicted in the film already exists in many forms in the country I love from a distance. Shootings, many of them mass in nature, happen every day in an America whose citizens are comfortable with violence but afraid of each other. The United States suffers from an embarrassingly high association with mass shootings, far more than whichever county manages to claim an ignominious second place. Whilst it is unlikely tanks and attack helicopters will surround the White House anytime soon, the casual spirit of violence that has overtaken American society already fosters a level of violence far above the threshold any twenty first century democratic state should tolerate.

I watched this film as a proud American and as a committed Christian, a faith I share with many of my fellow American citizens. My Bible, and theirs, does say we are “citizens of heaven” destined to enjoy an eternal posterity in a New Creation marked by perfect peace and prosperity. However, until Christ returns, and God remakes the cosmos, Christians do have a vital role to play in their everyday civic communities. Whilst Civil War offers a grim view of America’s immediate political future, that message of Christ contains the content needed to cure the gravest challenges bedevilling the United States. I remain optimistic.

Not all Americans identify as Christians or even with organised religion; nevertheless, twentieth century history confirms that states that altogether ignore God will soon wither into an ecosystemic abyss of state-sponsored moral relativism that endorses the use of violence for an increasing, arbitrary range of unsuitable, injudicious, and illegitimate purposes. The message of Christ applies to theocracies and secular states alike. Every state, regardless of its attitudes toward religion, has an interest in its people living together peacefully. Humans need a moral system to provide them (as well as their societies at large) with at least a perceived sense of moral structure. Christ’s message articulates a concept of civic love that challenges the existing worship of civic and political violence. Christ argues that violence in moments of disagreement or dismay is never the appropriate option; the mark of genuine Christian devotion is revealed in the avoidance of violent action even when the use of violence would not categorically be condemned by observers.

Civil War explains how multiple, competing Americas exist. These Americas have different cultures, economic capacities, and sociopolitical ideologies. It teaches that America’s main problem is Americans only love other Americans like them. A number of enclaves exist across American society. Cut off from each other, the development of these enclaves has led to the emergence of micro-Americas so distinctive from each other that some of them no longer view formal geopolitical ties with other micro-Americas as in their best interest.

The same enclavisation portrayed in Civil War exists in the nonfictional, real-life America. However, unlike in the America depicted in the film, the real-life America still has time to solve its sociopolitical troubles and stop the American state from collapsing. I recommend Civil War to anyone interested in being entertained and warned by what a dystopian, worst-case-scenario of near-future American political activity might actually look like.
