As you read, do you scribble around the edges? Over the years, writers have sworn by the practice. Edgar Allan Poe once wrote: ‘In getting my books, I have been always solicitous of an ample margin … for the facility it affords me of pencilling suggested thoughts, agreements and differences of opinion …’

I tend to make notes digitally nowadays. And if I include magazines and newspapers, most of my reading is online, where I probably could annotate with the right software, but can hardly doodle. That’s a shame. Apart from the fact that annotating boosts recall, we’d lose something if freeform margin-writing faded away. One of the meanings of ‘marginalia’ is ‘non-essential’, yet it’s anything but.

For one thing, scribbled-upon books have helped reveal the web of influences between writers and thinkers. Herman Melville’s annotated copy of John Milton’s Paradise Lost shows how it fed into Moby-Dick. And Charles Darwin’s comments in his books – from Charles Lyell’s Principles of Geology to his grandfather Erasmus Darwin’s The Temple of Nature – inform how they shaped his theory.

Marginalia can reveal everyday insights too. Historians occasionally find scrawls in manuscripts that speak of long-dead readers’ lives. A recent exhibition in Dublin features scriptures doodled on by medieval Irish monks. One described feeling ‘ale-killed’ (hungover); another complained about his materials (‘New parchment, bad ink. O I say nothing more’). Turns out nuns did similar. In 2022, researchers found surprisingly modern cartoons of people around the edges of an 8th-century Act of Apostles. A nun etched them, perhaps mischievously.

Reading about these examples made me think I should annotate more – not everything, but the writing I care about. Or perhaps I’ll take a leaf from a wholesome TikTok trend I discovered while writing this: gifting an annotated book. This 21st-century practice suggests digitalisation may not be annotation’s death knell after all. Poe might have approved.

For most of my 20s, I couldn’t brush my teeth, ride public transit, or take a walk without listening to a podcast or audiobook. Silence, I thought, was a waste of time.

But since reading All the Beauty in the World (2023), I’ve been reconsidering my relationship to dull, seemingly empty moments. In the book, Patrick Bringley recounts his decade among the watchful guards of New York’s Metropolitan Museum of Art. Standing in the Met’s echoic halls for hours on end, day after predictable day, he found that, over time, his relationship to the work slowly changed. Initial enchantment with the art gave way to boredom – and then, enlightenment. He surrendered to the ‘turtleish movement of a watchman’s time’, stopped thinking about how much of his shift was left, and let the hours drift.

I think about Bringley’s experience when I have to engage in any long, monotonous task. It might be waiting in line or on hold, vacuuming, folding laundry, or chopping vegetables for dinner. I resist the urge to fill the time with music or podcasts and strive instead for what Bringley calls a ‘princely detachment’ from time, finding the luxury and nuance in the moment.

Bringley noticed patterns in the different kinds of Met visitors. Hanging up my laundry, I notice patterns in how different articles of clothing tend to wrinkle in the wash. Bringley developed an appreciation for artworks that he initially ignored. I pay finer attention to the unique composition of facial features on the faces of people I stand in line with. I am learning, I think, to appreciate the little things.

Of course, it requires constant practice to find the peace and richness in these stretches of time. But your reward comes, Bringley says, when an hour no longer feels an hour long, and you ‘hardly remember how to be bored’.

The past is vividly alive in the Old Town of Würzburg in Germany. Walking the spindly streets, I felt transported to the medieval days: I could practically see the ruddy burghers going about their business in the shadows of aged church facades.

Often when we engage with things of the past, with the material lives of our forebears, we’re in search of a sense of authenticity. Seeing the actual items that people, long dead, dealt with in their day-to-day lives seems in some way to bring them back: what they’ve left behind invigorates our historical imagination of what their lives were like. The things that populated the lives of expired generations gives us a visceral connection to them, and Würzburg amply provides the material for that sense of intimacy with the vanished past.

Or so I thought. The same day I so romantically strolled through the Old Town, I learned that it’s not old at all – younger, in fact, than me. The Allies bombed the place to annihilation, destroying 90 per cent of the city (more than Dresden). After the war, the Würzburgers rebuilt the Old Town exactly as it had been, a project not completed until the 1990s. So while it seems that you’re engaging with the world of yesteryear, in fact it’s a reproduction.

And that shattered the connection to the past. But why? Walter Benjamin called the uniqueness of a work of art its aura. An identical poster of The Scream (1893), even if arranged the same way as the original, will resonate far less if the viewer knows that Edvard Munch’s brush never touched it. Its aura is gone. So, upon learning of its recency, the aura of Würzburg’s Old Town dissolved – and I was left instead with a sense of falsity, nothing but an unsettling replica of authenticity.

Often, forgetfulness is a mere inconvenience: that name, date or task that simply slipped through the cracks. But, sometimes, it’s downright unsettling to forget something. A friend asked me the other day: ‘Remember that hilarious dinner we had there a few years ago?’ And when for the life of me I couldn’t, I felt as if a slice of my existence had been cast into oblivion.

The ancient Greeks harbored a similar, if more pronounced, terror of forgetting. Plato associates forgetting with ‘non-being’, nothingness. Homer’s heroes do heroic things in order to achieve kleos (fame), and thereby defeat the destruction that comes with being forgotten. (As one of the Seven Wise Men said: ‘You will obtain memory through deed.’) Perhaps as a kind of buttress against the fear of forgetting, they anointed Mnemosyne, memory, the mother of the nine muses.

But I enjoyed learning the other day that this negative view of forgetting wasn’t shared by all ancient peoples. Daoism positively celebrates forgetting, indeed raises it to the status of an art. Zhuangzi, a founder of the tradition, urges people to master this art in order to gain a glimpse of Dao (the way), the eternal substratum of our passing world. As the philosopher Xia Chen writes, Zhuangzi’s idea is that the more of the world we’re able to forget – be it morality, history, the arts – the more we’re able to discover our true self, shaving off all that’s inessential to get down to the pith that we ultimately are.

Now, I don’t know if that will be of help when I inevitably confront the next lost memory, but it’s good to remember, if possible, that there’s a certain, subtle benefit in forgetting. ‘Only by forgetting,’ wrote the German philosopher Hans-Georg Gadamer, ‘does the mind have the possibility of total renewal.’
