Of all the things the human brain does, one of the strangest is this: it cries at fiction. It produces real, physical tears in response to events that never happened, involving people who do not exist.

And it does this reliably, repeatedly, across every culture and every era of recorded human history. We have always wept at stories. Around fires, in amphitheatres, in darkened rooms. Long before neuroscience had a name for any of it, we were letting imagined grief pass through us as though it were our own.

And yet we rarely stop to ask why.

We treat it as a given — of course films make people cry, of course stories move us — without ever sitting with how genuinely strange that is. That a sequence of images, a piece of music, a fictional character’s fictional grief, can produce a real physiological response in a real human body. That those tears are chemically identical to the ones you would cry at an actual funeral.

I started thinking about this through a confession that I offer without pride: the films that destroy me most reliably are animated. The Lion King. Spirit. I have come to terms with the slight embarrassment. What I could not come to terms with was the not knowing: Why does the brain — this extraordinary, overcomplicated organ that managed to invent language and calculus and sourdough — refuse to distinguish between a real loss and a drawn one?

The answer, it turns out, has three layers. And each one is stranger and more beautiful than the last.

Meet the Amygdala: Your Emotional Brain

The first thing to understand is that your brain does not fully believe a movie is a movie. Or rather — part of it does, and part of it absolutely doesn’t. Think of it as two women living in your brain and processing the information it receives. One is the prefrontal cortex — she is the rational, composed one. It’s the part of your brain that passed its exams and knows the difference between reality and a screenplay. She can register: this is fiction. These are drawings. But the amygdala, she’s the emotional one. She’s a small almond-shaped structure deep in the temporal lobe that processes emotion and social threat. It sees a face contorted in grief. It registers loss. It reacts. Full stop. The amygdala, in other words, doesn’t care that it’s a film. It doesn’t even care that it’s a cartoon. The amygdala, as they say in neuroscience circles, has not read the screenplay.

Mirror Neurons: Your Brain as a Simulation Engine

Now that you know about those two gals bossing around in your brain, let’s talk about monkey discoveries. In the early 1990s, a group of Italian neuroscientists at the University of Parma were studying motor neurons in macaque monkeys — the neurons that fired when a monkey reached for a piece of food. Fairly routine stuff.

What they stumbled upon by accident was that some of those same neurons fired when the monkey simply watched a researcher reach for food. The monkey wasn’t moving. Wasn’t touching anything. It was just looking. And yet, its brain was behaving as though it were the one doing the reaching. These became known as mirror neurons. In humans, the mirror system extends far beyond motor actions into the territory of emotional and social processing.

When you watch a character cry on screen — even an animated one, even a horse galloping alone across a prairie — a subset of the neural circuitry associated with your own emotional experience activates. Your brain builds an internal simulation of what that character is experiencing. You don’t just observe their feelings. You partially inhabit them.

This is why animators obsess over eyes and mouths above everything else. The close-up on Simba’s face after Mufasa falls. The way Spirit’s ears drop. These are not just artistic choices — they are, whether the animators understood it in these terms or not, direct inputs into the viewer’s mirror system. The more legible the emotion in a face, the more completely the brain simulates it.

This got me thinking about empathy. When people say “your pain is my pain,” we tend to treat it as a beautiful figure of speech, something poetic and kind but not quite literal. But it is literal. That is exactly what is happening in the brain. We do not just witness each other’s emotions from a safe distance. We simulate them. We run them, briefly, in our own nervous systems. “Your pain is my pain” is not a metaphor. It is a neurological description.

Which brings us, naturally, to the next layer.

Emotional Contagion: Catching Feelings Like a Cold

Mirror neurons seed something even broader that social psychologists call emotional contagion — the tendency for emotions to spread between people through observation and unconscious mimicry.

The mechanism is almost embarrassingly simple. When we observe an expression, we unconsciously replicate it in miniature: tiny, barely perceptible contractions of the same facial muscles. And here is the part I love: the face doesn’t just express emotion. It also produces it. Feedback from those micro-expressions travels back to the brain and generates real feeling. The body tells the mind how it feels, not only the other way around. So your face starts mirroring the grief on screen — and then your brain, receiving those signals, generates the actual chemistry of that emotion. You have been, quietly and without your consent, infected by a feeling that originated in a drawing.

I think this is also why watching these films in a cinema hits differently than watching them alone at home. Emotional contagion doesn’t just travel from screen to viewer — it travels between viewers too. The collective held breath during a brutal scene. The person two rows ahead whose shoulders are shaking. Without knowing it, they are nudging your nervous system in the same direction. A theatre full of people watching the same story is not a collection of separate emotional experiences. It is one resonant system. Which is why we should all go to the movies more often. Seriously.

Now let’s move to some chemistry.

Oxytocin: The Chemistry of Borrowed Grief

Once emotional contagion takes hold, the brain begins releasing oxytocin — a neuropeptide associated with bonding, attachment, trust, and social connection. It lowers emotional inhibition and makes us more receptive to other people’s feelings. Think of it as the brain quietly deciding: this matters, stay emotionally open.

What fascinates me is that oxytocin does not require a real relationship to activate. The brain is surprisingly willing to form emotional bonds with fictional people. Or lions. Or horses. Neuroeconomist Paul Zak spent years studying what triggers oxytocin release and found something extraordinary: a well-constructed narrative alone can produce measurable increases of oxytocin in the bloodstream. No physical contact. No lived experience. Just a story, emotional stakes, and a character we care about.

In other words, the brain does not bond exclusively through direct experience. It bonds through narrative. And once that bond forms, the emotional consequences become real. The grief feels real because, neurologically speaking, the attachment became real first. The brain does not treat stories merely as information. It treats them as social experiences.

Which suddenly makes a lot of sense when you think about how humans evolved. Stories have always been how we transmit fear, morality, love, danger, and memory. The nervous system learned long ago that paying attention to other people’s experiences — even imagined ones — might matter for survival. So when Mufasa dies, your brain does not calmly file the moment away under “fiction.” It reacts to the loss of someone it has emotionally invested in.

And Then Come the Tears

Now, all of the above — the amygdala, the mirror neurons, the contagion, the oxytocin — explains why you feel the emotion. But what actually brings us to tears?

Here is the chain of events.

The amygdala, now fully convinced that something worth grieving is happening on screen, sends a distress signal. That signal reaches the autonomic nervous system — the part of your nervous system responsible for all the things your body does without asking permission: heart rate, breathing, digestion. The autonomic system has two branches. The sympathetic branch controls the fight-or-flight response. The parasympathetic branch calms the body back down. And this is where things become strangely beautiful.

The parasympathetic system is directly connected to the lacrimal glands — the glands responsible for producing tears. When emotional intensity activates this system, tear production follows automatically. So tears are not, strictly speaking, emotional. They are physiological. Your body is performing a physical response to an emotional signal. You are not choosing to cry. A very old part of your nervous system is crying for you.

And here is the detail that stopped me completely when I found it: emotional tears are unique to humans. We are the only species on earth that sheds them. Every other animal — including our closest primate relatives — has lacrimal glands, but uses them only to keep the eyes clean and lubricated. The idea that a strong feeling could overflow through the eyes, that grief or joy could become something visible and wet on a face — that appears to be, as far as we know, ours alone. And I think that is worth sitting with for a moment.

The Neuroscience of Feeling Seen

Maybe this is the real reason stories matter so much to human beings. The brain was never designed to function as a perfectly objective machine, carefully separating reality from fiction at every moment. It evolved for something far messier and far more beautiful: connection.

To attach. To simulate the feelings of others. To let another being’s grief — even an imagined one — pass briefly through our own nervous system. And perhaps that is why art has always mattered. Not because it tricks us, but because it reaches the very systems that make us social creatures in the first place.

There is something I keep coming back to. The filmmakers who made The Lion King — the animators who agonised over the angle of Simba’s ears, the composers who chose that particular swell of strings — none of them needed to know any of this. They did not consult a neuroscience paper. They just understood, intuitively, how to reach inside a human being and press the right buttons. And the brain, faithful and ancient and slightly gullible, responded exactly as it was built to.

Maybe that is what art has always been. Not decoration. Not entertainment. A very precise, very human way of making each other feel less alone — one common grief at a time.

For centuries, humankind has tried to make sense of life on Earth through art. That is the beauty of art itself: its ability to adapt, to continue to make sense for years- centuries even- after it was created. Art becomes more than a momentary emotion; it becomes a kind of collective diary, a record of what those before us felt, what we knew about ourselves, and how we understood the world.

So much of our history has been reconstructed through the art that has been left behind by our ancestors. That is the strength of art. The eternal meaning that it carries, the way it holds memory. But like all beautiful things, art is fragile: it exists through materials, elements, pigments, wood, canvas, and stone. That is art’s weakness. It can be damaged, destroyed, erased, and with it, all it holds. History has shown us how easily art can decay or disappear, and without it, part of our story fades too.

This is why it becomes essential for us to use every tool we have- technology, chemistry, physics- to preserve what time attempts to undo. Science allows art to keep doing its magic. To protect it, understand it, and preserve the meaning it holds. Science becomes essential in ensuring the legacy and endurance of art itself.

Most of my life, I thought science only looked at the future- Will we survive on Earth? Is time travel possible? Should we colonize space? That sort of Stephen Hawking-type question. Why would science concern itself with the past? And especially with the artistic past?

Truth is, science is often described as the most rigid of endeavors. I beg to differ.

Sure, science is strict in its methods, but it is broad and welcoming in its purpose. It is in the interest of science to explore, yes, but also to protect. For the sake of remembering who we are. For the sake of leaving something behind. For the sake of humanity’s endurance.

But how? Really, how can science help? Well, while going through one of my little obsessive tantrum phases about this, I found out about the Louvre’s laboratory, and I just had to write about it.

The Louvre’s underground lab- C2RMF

I live in Paris, home to some of the greatest museums and art collections in the world. So, let me reintroduce you to The Louvre- I’m sure you’re acquainted- but he’s got a lot of secrets.

Its collection includes over 500,000 works from prehistory to the 21st century, of which only 35,000 are on display at any one moment, while the rest lie in storage, research, or off display.

Now, when I read this, I thought: that is a lot of art. Very cool numbers. Research though? What is there to research about? I went down the rabbit hole and found the C2RMF.

Beneath his marble floors, far from the crowded halls of the Mona Lisa, the Louvre has another kind of gallery, made of microscopes, infrared cameras, and spectrometers. Filled not with wandering tourists, but with busy scientists. It is called C2RMF- which sounds like the name you’d give to a Star Wars robot character- but it actually stands for Centre de Recherche et de Restauration des Musées de France (the research and restoration center for the Louvre and all national museums in France). In these underground, hidden rooms, science becomes the guardian of art’s memory, uncovering the stories hidden beneath each layer of pigment, mapping the materials that time has worn, and working to protect fragile masterpieces so that they can endure for centuries more.

There, you’ve met the C2RMF, this underground dude that likes to keep to himself, now, let’s try and understand the science that goes on in there. I’ll give you a tiny crash course on the basic science first, then I’ll take you on from there.

The Chemistry of Color

All paintings are chemical objects. Why? Well, everything that surrounds us is a chemical object, and funnily enough, your primary school drawings are made of the same chemical compounds and follow the same chemical process as a Van Gogh canvas. Congratulations, Vincent, you’re a genius.

But on a serious note, you and good old Vincent are subjected to the same rules of chemistry. More specifically, the chemistry of pigment.

Paintings are made of colors on canvas, and color is given by a very cool type of chemical compound called pigment.

Just like any chemical compound, each pigment has its own chemical identity, a sort of chemical blueprint that, if studied, can tell you pretty much everything you need to know about its past and its story.

Let’s take ultramarine color, for example. A gorgeous, brilliant blue, made from crushed lapis lazuli, a once very precious stone. Or lead white, a warm, bright pigment, whose chemistry slowly changes over time and can cause the surface to darken. Or vermillion, a deep red made from mercury sulfide. Again, every single pigment of a canvas has an identity and a story.

It is the scientist’s job to dig out these stories, to identify a color’s origin. Where a pigment came from. Which workshop used it. Whether it was common or rare. Whether it matches what we know about the artist. It’s like playing detective with art and chemistry. Sounds like tremendous fun.

To be the Sherlock Holmes of art, scientists use tools like Raman spectroscopy, X-ray fluorescence, X-radiography, and Infrared Reflectography. A lot of consonants there, ugly words, I know, but I’ll break it down, it’s really not that bad, I promise.

Raman Spectroscopy- the “Molecular Fingerprint” of Pigments

Now let’s start with the name, Raman Spectroscopy- I like the Raman part; it reminds me of ramen, but spectroscopy, really, seriously, scientific community, stop it. Nonetheless, I’ll tell you what it is. Spectroscopy is a technique used to analyze the properties and compositions of a given substance, which essentially involves the interaction of light with matter. Add Raman to it, and you get one of the most important tools used in the Louvre’s labs. Scientists love it because it allows them to identify a pigment without taking anything from the painting.

The concept of Raman Spectroscopy is essentially what happens when scientists decide to play detective. It works almost like a molecular fingerprint scanner. A tiny laser is pointed at the paint- and most of the light bounces back unchanged. But a tiny portion interacts with the pigment’s molecules and comes back with a slightly different energy. That shift is unique to each pigment, like a molecular fingerprint. Every pigment — lapis lazuli, malachite, lead white, vermillion — has its own Raman “signature.”

I said scientists like to play detective, well, Raman Spectroscopy is sort of like when the detective finds out who the killer is by analyzing his fingerprints. Each pigment has its own molecular “print,” and Raman can read it with incredible precision, going way beyond what the naked eye can see.

From these fingerprints, scientists can start deducing information. For example, some pigments simply did not exist during certain historical periods, so finding one on a canvas can help date the artwork or reveal that parts of it were later added. Or spotting modern pigments, making it easy to detect restoration, retouching, or even forgeries. Truth is, the chemistry just cannot lie. If I analyzed my version of The Starry Night with Raman, then compared it to Van Gogh’s original, the truth would be exposed instantly: the pigments I can buy today simply aren’t the same as the ones he used back in 1889; their molecular fingerprints are different. Now I don’t need Raman Spectroscopy to tell me that my canvas is not an original Van Gogh, it would be pointless to even try and claim it is, but say a better painter, a good forger, tried to pass a copy as an original- even if the brushstrokes were perfect and the resemblance uncanny, the science would reveal that the materials come from a time and place Van Gogh never had access to.

X-ray fluorescence- a time machine for art

Now stay with me, because this is actually a really cool scientific tool- it’s like rewinding the clocks on an artwork and watching its creation process.

XRF provides an elemental map, essentially a picture of the chemical elements that are inside a painting.

Here is the general idea of how it works: A beam of X-rays (energy) is aimed at the surface of the artwork. When the atoms in the pigments that make up the artwork absorb that energy, they become excited. It sounds funny, but that’s pure physics. Atoms have electrons arranged in different energy levels, like floors in a tiny apartment building. Under normal circumstances, each electron chills on its assigned floor, minding its business. If you shine light on the atom, its electrons get all excited and go up in energy level. When they relax back down, they emit their own tiny bursts of energy- a kind of “glow” invisible to our eyes. That glow tells scientists exactly which elements are present.

By now, you should understand that every chemical element, compound, has its own identity, its own signature, so you shouldn’t be surprised if I told you that different elements produce different signals. That is, each element releases energy at certain exact frequencies. Once the elements are identified, the pigment they come from can be found. Lead (Pb) appears in lead white, Copper (Cu) in azurite, malachite, and verdigris, Iron (Fe) is in ochres and earth pigments, and Mercury(Hg), that’s vermillion.

What makes XRF so powerful is that it can scan large areas and create full-color elemental maps of an entire painting. These maps reveal all sorts of secrets: hidden paintings under the visible one, erased figures, changed compositions, earlier restoration attempts… even pigment degradation that’s happening slowly over time. Like Raman it’s non-invasive and safe for the artwork, and it’s practically X-ray vision but for art.

But my favorite part is how XRF can rewind time. It reveals not just what the painting looks like now, but how it once was, and how it came to be, making it possible to retrace the different stages of an artist’s creative process. If XRF picks up heavy metals beneath the visible surface, it might reveal an abandoned composition underneath. Suddenly, a painting isn’t just an image. It’s a history of choices.

Infrared Reflectography- Peeking at the Artist’s First Draft

Like snooping through the artist’s sketchbook, the messy first draft behind every masterpiece. And honestly, who doesn’t want to know just how much the artist trusted the process? Infrared light can slip through many pigments, but it gets stopped by carbon, which is great, because a lot of underdrawings were made with charcoal or graphite. When conservators shine infrared light on a painting, the top layers become almost transparent, revealing the ghostly black lines underneath. Suddenly, you’re looking at the artist’s earliest thoughts: figures they erased, outlines they changed, ideas they abandoned (relatable). It’s like discovering that even geniuses hesitate, redesign, and sometimes go “nope, not that” before landing on the final image.

X-Radiography- The “Full-Body Scan” of a Painting

X-radiography is what happens when you treat a painting like a patient getting a medical checkup. A sort of Dr. House for artists- instead of looking at a medical history, it is the artwork under scrutiny, and the secrets are bound to come out. The same kind of X-rays used in hospitals pass right through the artwork- and the denser the material, the more it shows up. Lead-based pigments? They shine bright white. Thin organic pigments? Practically invisible. The result of X-Radiography is a black-and-white image that reveals everything hiding inside the painting’s structure: older compositions painted over, hidden figures, earlier repairs, nails, wood grain, you name it. While infrared shows you the artist’s first sketch, X-radiography shows you their entire painting history, layer by layer, mistake by mistake, all the way down to what they tried to hide.

Each of these imaging tools works to uncover the truth, the story behind the layers of pigment, stories that have been hidden for centuries. Science becomes a way of reading art. More than that, it allows its truth to be uncovered, and it ensures its protection.

The silent guardian of art

Now, I’ve talked your ear off with all of this, I know, but I hope that with this knowledge, you’ll be able to appreciate that this goes beyond mere chemistry and physics. It is about giving art the chance to keep speaking to our hearts and minds long after its materials should have expired. This collaboration between art and science ensures that the stories woven into these materials- the ones we use to understand ourselves, our history, our humanity- don’t simply vanish. Art may be fragile, but I really believe that with science’s help, it might be able to pass the test of time and continue to be the most touching and sincere of human endeavors.

I hope you now have a slightly better understanding of what happens in the C2RMF. I hope the next time you happen to be in front of a painting, you can appreciate how fleeting its nature could be and maybe ask yourself what might be the story of those brushstrokes or the secrets that the pigment hides. I hope you’ll believe that so long as we continue to question what lies beneath the surface, the memory held by these works will endure.

And as always, I hope you can recognize that art and science can depend on each other. A reminder that understanding is an act of love, and art is full of love.

I started thinking about this while reading Irving Stone’s Lust for Life, a biographical novel about Vincent Van Gogh. In the book Stone describes an evening in a Parisian attic where Van Gogh is introduced to Georges Seurat and his groundbreaking, controversial theories about paint.

I soon realized that the encounter between the two painters was so much more than a 19th century’s idea of networking. It was the collision of two ideals. Whilst Van Gogh argued that the essence of painting lies in the expression of the individual, experience and movement, Seurat wanted to make painting an abstract and mathematical science.

Of course, Seurat’s theories and ideas were funny, oftentimes considered ridiculous by the art critics of the time, but today, I wondered, can we consider art and science opposites?

Can we still say that they occupy fundamentally different perspectives?

Can’t they be mutually used as tools in the pursuit of truth?

I went through a little obsessive tantrum phase about this, and started researching, trying to understand, trying to give myself some answers. Being a physics and chemistry student, I dived into Seurat’s reasoning, at the roots of his scientific painting and thought I could share what I had found.

So let me take you back a couple hundred years, hop on a dusty old train, destination Paris, France.

We’re in the 1880s, under the tumultuous wave of Impressionism, and at night as most of the city sleeps, somewhere in Paris, shimmering lights are reflecting on the glass of an attic’s window. It looks like magic. It will be later called- Pointillism.

Georges Seurat’s Trouble

We are at a time where Impressionism is taking over the studios and art galleries of Paris. It is revolutionary, shocking to most.

But why did Georges Seraut- one of the many Impressionists of the time- decide to move further, dive deeper into the study of color?

Georges Seraut was a hardcore Impressionist: he wanted to be able to transmit exactly the colour he was seeing with his own two eyes, sitting on a stool on the banks of the Seine. He wanted to dominate colour, he wanted to shape light. After several years of experience with colour and paint, he became aware of his biggest problem: Pigments and light. So he studied the physics of pigment and light and transformed painting into a methodical science.

The science of color and vision:

In order to capture modern life sunlight and shimmering rivers artists strived to be able to fully transmit onto canvas not only shade and tone, but also brightness and vibrancy. Their trouble was that pigments behave very differently from light.

In pursuit of an answer, Georges Seraut soon became interested in the work of Scottish physicist James Clerk Maxwell. In particular he followed his studies on how the eye can fuse light into new colors. Maxwell had created a simple device: a spinning disk painted in different colors — half red, half green for example, and made it spin rapidly. The disk no longer appeared in two halves but in a uniform yellow. Maxwell’s experiment demonstrated that the eye itself blends signals.

During that time the American physicist Ogden Rood went on to build on Maxwell’s work by distinguishing between pigments and light.

Let’s take a little step back, what is light and what is pigment?

Light is electromagnetic radiation, essentially energy that travels in the form of electromagnetic waves. All the colors we see — the rainbow from violet to red — are just light waves of different lengths. Our retina (the light sensitive layer in our eyes) has three types of cone photoreceptor cells, each tuned to a different range of light wavelengths: short (blue), medium (green), and long (red). The brain compares the signals from these cones to reconstruct every color we see.

Shine red and green light together, and the brain perceives yellow. Combine all three primaries of light — red, green, and blue — and you get white. This property is called additive mixing in which more is literally brighter: the more light you add, the closer you move to dazzling white.

A pigment on the other hand, is a chemical compound that gives a substance color by absorbing or reflecting different wavelengths.

Imagine being in art class and mixing paints on a palette. The colors rarely stay bright. Each pigment absorbs certain wavelengths of light and reflects the rest. When multiple pigments are combined, they “subtract” more and more light from what reaches the eye, leaving a result that is darker, duller, and often brownish.

The subtractive mixing nature of pigment is what caused Georges Seraut to stop mixing pigments directly on his palette.

How could Georges Seraut avoid killing brightness in his canvases? How could he capture the intensity of sunlit rivers and glowing Parisian boulevards?

He couldn’t possibly shine light on a white canvas, nor could he refrain from using paint.

Luckily enough, during that time, art wasn’t the only expanding field. It was a tumultuous time for science as well.

Enter Chevreul and Ogden Rood

As chemist Ogden Rood explained, mix pigments on a palette and the result is subtractive and often dull. But place small dots or lines of pure pigment side by side, and the eye performs something closer to additive mixing, creating luminous new shades.

The renowned French chemist Michel Eugène Chevreul after being appointed director of the dye works in a tapestry factory in Paris in 1824, noticed that a gray thread looked bluish when next to yellow, but took on a reddish tinge when next to green. He developed what became known as the law of simultaneous contrast — the principle that colors seem to change depending on their neighbors.

Seraut didn’t need to know more. He understood the science behind art, now it was time to craft and perfect a scientific method to apply to his art.

Seraut’s scientific method for painting: Optical mixing

Seraut translated Chevreul’s law of simultaneous contrast and Rood’s additive mixing, and started to paint with physics as much as with pigment. By cleverly juxtaposing pigments he could make hues appear brighter and rather than blending colors with his brush, he applied surgically precise dots of pure pigment so that from a distance, it would be the viewer’s eye doing the mixing. His canvases became interactive optical experiments. The result? The colors of his canvases appeared vibrant, glistening, alive. He could finally paint what he was seeing. He could finally paint light.

A final answer or an open question?

Seurat’s method was revolutionary for two reasons:

Firstly, he had transformed scientific theories of light and vision into a new style of art, letting the canvas become a full on laboratory.

But secondly and maybe most importantly, he had implied that art can and should be made an abstract science. He argued that a mathematically precise use of color did not inhibit the beauty of his work, more so, it enhanced it.

So here we are again, reaching the big old question: Does science’s rigidness hinder artistic freedom?

While science’s mantra is accuracy and repeatability, art embraces creativity and feeling. Yet when they come together, as they did in Neo-Impressionism, they challenge us to see differently, to ask whether beauty really can be mathematical, and whether originality can also be an act of imagination.

I have struggled a lot to put into words the conclusion I came to in my heart.

Perhaps, art and science are simply two ways of exploring the same mystery of perception. Rather than being rivals, they are companions, both trying to understand and communicate with the world.

Perhaps their meeting point is not to give answers but to raise questions, to invite the observer to look closer, question, wonder, imagine, write a whole article about it.

Their meeting point is not a final answer but an open question.

💬 What do you think — can art and science fuse, or should they stay as far apart as possible? Share your thoughts below, I’d love to hear your perspective.
