Χρόνος and Καιρός

“The part of life we really live is small. For all the rest of existence is not life, but merely time.” — Seneca

Chronos measures time; Kairos gives it meaning.

The ancient Greeks had more than one word for time.

There was Χρόνος (Chrónos), the time that flows relentlessly, measured by clocks, calendars, and the ageing of our bodies. It is the time that runs, pushes us forward, and often makes us feel we are always late for something.

But the Greeks also spoke of Καιρός (Kairós): the right moment, the opportune moment, the instant when circumstances come together and something becomes possible. Unlike Chronos, Kairos cannot be measured in hours or minutes. It must be recognized.

Perhaps we spend too much of our lives chasing Chronos, when we should sometimes pause and listen for Kairos.

There is a time to sow, a time to harvest, and a time to let the earth rest. There is also a time to act, and a time to wait.

Interestingly, other ancient cultures developed similar ways of thinking about time. In Sanskrit, Kāla (काल) refers to time in its chronological and universal sense, while Ritu (ऋतु) describes time as a season or a qualitative moment—a period defined by its particular nature and significance.

The curious thing is that time does not pass at the same speed for everyone. A minute of anxiety can feel like an hour, while an entire afternoon of happiness may disappear in an instant. A child experiences summer as an eternity; an adult may wonder where the years have gone.

Chronos is the time we share. Kairos is the time we experience.

The deepest mystery of time, for me, is not how quickly it passes, but why it feels so different depending on who we are, what we are doing, and what we are waiting for. Two people can share the same hour, the same year, even the same lifetime, yet experience it in profoundly different ways. The distance between them is not measured in space, but in the way they inhabit time—as if they were living in different dimensions.

Which kind of time are you living in today?

The image shows a relief of Kairos, the personification of the opportune moment. Why the long hair at the front and the bald back of his head?

The symbolism is brutally simple: when Kairos approaches, seize him by the hair. Once he has passed, there is nothing to hold on to. No amount of regret can bring the opportunity back.

The original reliefs associated with Kairos are preserved today at the Archaeological Museum of Trogir, Croatia, and the Kunsthistorisches Museum in Vienna.

The Exposure of Time

Not so long ago, before the digital age, photographs were fixed on silver gelatin photographic paper. But there are other, far more powerful mediums capable of freezing a moment — sometimes even an entire civilization — in space and time: ash and forest.

Take Pompeii. In AD 79, the eruption of Mount Vesuvius abruptly brought life in the city to a halt, burying its streets, houses, and inhabitants beneath volcanic debris. Pompeii became, in a sense, a three-dimensional photograph of a precise moment in time. Walking through its streets today, we can still see traces of everyday life interrupted: decorated houses, shops, familiar objects, inscriptions on the walls. Everything seems to tell us what was happening just moments before time stopped: the bustle of the streets, voices mingling, merchants calling out to passersby, children crying, lovers meeting away from prying eyes. As if all those lives had been imprinted in stone.

Then there are the Maya cities, such as Palenque. Here, the shutter seems to have worked much more slowly. It did not capture a single moment, but the gradual disappearance of an entire civilization. After the city was abandoned, the tropical forest slowly covered its temples, palaces, and plazas, until it almost completely absorbed them.

At Pompeii, ash stopped time. In the Maya cities, it was the forest that covered it.

Two very different ways of preserving the past: one through a sudden interruption, the other through the slow return of nature. In both cases, what we discover today bears a strange resemblance to a photographic image — except that here, the image is three-dimensional, and its frame is time itself.

And there is something quite extraordinary about that: time, which normally erases everything, has left an image behind. An image without film, without a camera, without a photographer.

And perhaps that is the most haunting photograph of all: one that no one ever took, but that time itself developed.

YAACOV AGAM — YOU NEVER SEE IT ALL

“When I finish a work, it is just starting.” — Yaacov Agam

One of my favorite Op Art artists and a true visionary, Yaacov Agam (Hebrewיעקב אגם) was a pioneer of kinetic and Op Art. His work explored movement, color, time, and perception, making the viewer an active part of the artwork rather than a passive observer.

Born in Rishon LeZion in 1928, Agam studied at the Bezalel Academy in Jerusalem and later with Johannes Itten in Zurich. He moved to Paris in 1951, where he became one of the leading figures of the European avant-garde. His first solo exhibition was held there in 1953.

Agam died in June 2026, at 98, after receiving the Israel Prize for Visual Arts. His work is represented in major museums around the world.

Among his most remarkable achievements is the Salon Agam, commissioned by President Georges Pompidou for the private apartments of the Élysée Palace and created between 1972 and 1974. Now in the collection of the Centre Pompidou, it is essentially a kinetic environment: walls, doors, ceiling, carpet, color and geometric forms change as the viewer moves through the space.

Agam understood something fundamental about visual art: the work is not always what you see. It is also what happens when you move, look again, and see something different.

Is Nature Already a Work of Art?

Art may not be exclusively a human affair. Nature has its own creative force and aesthetic power. Crystals, shells, clouds, and landscapes produce forms and patterns that we often find as fascinating as works made by artists.

Without disturbing Kant too much—and his somewhat dated distinction between natural and artistic beauty—where does art actually begin?

Nature: the original artist?

Nature creates without any apparent intention. It does not try to please us or express an idea, yet it can produce forms of extraordinary complexity and beauty.

  • Spontaneous beauty: Crystals, landscapes, spirals, symmetries, and biological patterns can display structures we perceive as beautiful.
  • Creation without a plan: Nature produces forms without an artist, a blueprint, or even an audience.
  • Our first inspiration: From the beginning, humans have observed, imitated, and transformed natural forms into their own creations.

For Kant, this is precisely where the difference lies: a work of art involves intention and a concept of what it is supposed to be, whereas natural beauty can be appreciated without knowing any purpose behind what we see.

But is intention really necessary?

Does art require intention?

The idea that we must know what an artist intended in order to understand or judge a work has been questioned for a long time. In 1946, William Wimsatt and Monroe Beardsley famously called the attempt to use an author’s intention as the basis for interpretation the intentional fallacy.”

And art can go even further.

It can be improvised, accidental, discovered rather than made. It can emerge from a chance encounter between an object and a particular way of looking at it.

Leonardo da Vinci already understood this. He suggested looking at stains and irregular patterns on old walls because they could trigger visions of landscapes, battles, figures, and strange compositions. Chance could become a generator of images.

In other words, the work is not always entirely in the object.

Sometimes, it appears in the eye of the beholder.

Take a stone polished by the sea. It might suddenly remind you of a sculpture by Henry Moore. Nobody sculpted it. Nobody intended it to represent anything. Yet your brain detects a form, gives it meaning, and perhaps even sees a sculpture.

So—is it art?

From found object to readymade

With Marcel Duchamp, things get even more complicated.

The readymade takes an existing object, removes it from its ordinary context, and presents it as art. Duchamp began exploring this idea as early as 1913 with Bicycle Wheel.

The object itself may have little or nothing to do with traditional ideas of beauty. What changes is the context, the choice, and the way we look at it.

Art therefore moves, at least in part, from something made by the artist to something that can be selected, discovered, and reframed by the artist.

And this makes the boundary between creating and discovering surprisingly thin.

A natural form can resemble a sculpture. A stain can become a landscape. An ordinary object can become a work of art. And sometimes a work becomes art only because someone recognizes it as such.

Perhaps the artist does not always create something from nothing.

Sometimes, the artist does something more subtle:

he reveals what everyone else was looking at but never saw.

So where, exactly, do we draw the line between art and non-art?

And ultimately, what makes something art: the object, the artist’s intention, or the eye of the beholder?

Theodelinda: the queen who shaped Italy

Theodelinda (c. 570–627) was one of the first women to exercise political power over a large part of Italy, and one of its longest-serving female rulers. Queen of the Lombards from 589 to 616, she then governed as regent for her son Adaloald until 624—about 35 years in all.

She was influential less through military force than through diplomacy and religion. A Catholic queen in a largely Arian Lombard kingdom, she promoted closer ties between the Lombards and the Catholic Church and helped foster a more peaceful coexistence between the Lombard and Roman populations.
She made Monza her preferred royal residence and founded the basilica of St. John the Baptist, laying the foundations of the city’s extraordinary religious and cultural heritage.

Her reputation endured for centuries: Theodelinda became one of the most celebrated women of early medieval Italy—not because she conquered a kingdom, but because she helped hold one together.

When AI Writes What We Want to Read

Sometimes I wonder how we got here. As someone who has spent a lifetime reading and writing, I can usually spot AI-generated prose. The clichés, recycled formulas, suspiciously polished sentences, and repetitive rhythms often give it away. But apparently, most readers can’t. That’s a little unsettling.

A peer-reviewed study from Villanova University asked 1,682 people to read six short stories. Sometimes they were correctly told whether the author was human or AI; sometimes they were deliberately misled.

The result is uncomfortable.

The AI-written stories were rated 6% higher in quality and 8% more engaging than the human-written ones. Even more telling: when readers believed an AI story had been written by a person, they rated it even higher.

The real story isn’t AI. It’s us.

We don’t necessarily value authenticity—we value the belief that something is authentic. We romanticize the author’s life, struggle, and voice. Remove the label, and our judgment shifts.

AI may not have become a writer. It may simply have become remarkably good at producing the kind of prose that feels familiar, readable, and broadly appealing.

The disturbing question isn’t whether AI can write. It’s whether we can still recognize a genuine voice—or whether we’ve grown so comfortable with the average that we mistake it for excellence.

And yet, there is another layer to this uneasiness. It brings to mind Roland Barthes, who famously wrote: “The birth of the reader must be at the cost of the death of the Author.”

Barthes argued that meaning ultimately belongs to the reader, rather than to the author’s intentions or biography. AI adds a rather disturbing twist to that idea: what happens when the Author is no longer even a person—and when the reader cannot reliably tell the difference?

Beyond the conformity and mediocrity that AI may encourage, this makes me wonder how little we actually know about why we like what we read. Perhaps the real illusion is not that AI has learned to imitate us, but that we are far more predictable than we ever imagined.

Lions, Elephants, and the Medieval Imagination

Lions had already appeared in Roman arenas, where they were set loose to devour Christians. Hannibal famously dragged elephants across the Alps. Yet, strangely enough, very few artists left us reliable images of these exotic beasts from the time.

So, centuries later, European artists faced a minor problem: how do you draw an animal you have never seen?

Simple. You copy someone who also never saw it.

This was the medieval version of the telephone game. A lion might be described in a manuscript, copied from an older drawing, or reported by a traveler as “a huge cat with a mane.” Each artist then copied, misunderstood, embellished, and passed the result on. After enough generations, the lion could acquire a human face, bizarre feet, and the general appearance of a creature that had escaped from someone’s nightmare.

The same problem survived well into the Renaissance. Take Albrecht Dürer’s famous 1515 rhinoceros. Dürer had never seen a rhinoceros. He worked from a written description and a sketch made after a real Indian rhino arrived in Portugal. He added armor-like plates that the animal did not actually have.Yet his rhinoceros became so influential that Europeans kept copying Dürer’s imaginary details for centuries.

There is something wonderfully philosophical about this: we rarely inherit reality itself. We inherit other people’s descriptions of it—and then confidently mistake the copies for the truth.

Before War Had a Name

Since humans learned to stand upright without wobbling too much, they also learned how to organize confrontation—and how to justify it, which sometimes requires more invention than the act itself.

The archers painted on the rock shelters of the Spanish Levant—particularly in the Castellón region, around sites such as Morella and the Cueva del Roure area—belong to a broad artistic tradition dated to the late Mesolithic and early Neolithic (roughly the 7th to 6th millennia BCE). They are among the earliest narrative images known in Europe. The scenes show hunting in motion, and in some cases have been read as episodes of intergroup conflict.

Archers facing each other at Cueva del Roure, in Morella (Castellón). The scenes depicted in the Levantine Spanish rock paintings, dating to the 6th millennium BCE, are among the earliest known representations of warfare.

What is clear is not the confirmed presence of war, but the early shaping of its story. From very early on, humans did more than strike—they composed. They organized action into sequence, gave it form, and turned events into something legible. And perhaps that is where the deeper history of power begins: in the ability to convert chaos into composition.

So is war in our DNA?

No. DNA does not encode behavior. It defines capacities that are shaped by culture, history, and environment. Still, it leaves a clear paradox: we are built to cooperate, and we are built to exclude. Early humans lived in tight-knit groups, bound by cooperation, while competing with other groups for resources. That tension likely shaped both empathy and aggression.

The brain still carries traces of it. The amygdala rapidly classifies “us” and “them,” triggering threat responses, while the prefrontal cortex helps regulate and reinterpret them. Culture largely determines which patterns dominate. We see the same mechanism today in digital echo chambers, where similarity is continuously reinforced and difference flattened.

Organized warfare, as we recognize it today, appears relatively late in the archaeological record. Clear and recurring evidence becomes more visible around 14,000–10,000 years ago, and expands with the rise of sedentary and agricultural societies. Homo sapiens, however, has existed for roughly 300,000 years. Across most of that span, the evidence points more toward small-scale, episodic violence rather than sustained, systematized warfare.

War, in this sense, may be less an ancient biological destiny than a comparatively recent cultural development—built upon older cognitive and social instincts.

P.S. Early language systems such as Proto-Indo-European—the reconstructed ancestor behind many European and some South Asian languages—did not rely on a single abstract word for “war.” Conflict was instead described through specific acts like raiding, fighting bands, or disputes. The idea of “war” as a unified concept came much later, which is why Indo-European languages still reflect different, unrelated roots for it today.

Born into Iki

I am iki from birth.

But what is iki (粋)?

Edo, under the Tokugawa shogunate. Merchants wealthy enough to unsettle the hierarchy, yet still ranked below the samurai. Power without status—watched closely, dressed carefully.

Sumptuary laws did the rest: no gold, no loud silk, no bright declarations. Only browns, greys, indigo. A forced muting of visibility.

Constraint rarely suppresses imagination. It concentrates it.

From this narrow register emerged a refined spectrum known as Shijuhattcha Hyakunezumi (四十八茶百鼠)—“48 browns, 100 greys.” Not literal numbers, but a cultural way of naming excess within restraint: an almost infinite sensitivity to difference inside what first appears uniform.

Fashion became a coded language. Subtle shifts in tone, legible only to trained eyes. Outside, discipline. Inside, excess held in reserve. A lining of rare fabric. A color hidden against the skin. A private flash revealed only when a sleeve turns in the wind.

This is iki: elegance that refuses emphasis. Presence without display. A form of refinement that collapses the moment it is named.

Its opposite is yabo (野暮): excess, insistence, the compulsion to be seen. Not morality—measure. Or the lack of it.

Today, the direction has inverted. Visibility has become currency. Those who do not perform disappear; those who do not declare are not counted. What was once failure has become strategy.

And yet the counter-move remains simple.

Lower the volume. Leave gaps. Let meaning breathe in what is not shown.

And become something worth looking at twice.

How a Human Bone Inspired the Eiffel Tower

Few people know that the human femur—the body’s largest and strongest bone—played an indirect role in the thinking behind the design of the Eiffel Tower.

Part of the tower’s structural logic can be traced to Swiss engineer Maurice Koechlin, chief engineer in the firm of Gustave Eiffel. While determining how forces would travel through the iron frame, Koechlin applied a principle that places material along the natural paths of tension and compression.

A comparable pattern had been described earlier by Zurich anatomist Hermann von Meyer. His research revealed that the femur’s internal structure forms a network of delicate struts known as “trabeculae.” These tiny elements follow the directions of mechanical stress inside the bone, creating a highly efficient system of support—even though the femoral head sits off-center from the shaft.

The mathematician Karl Culmann later showed that these trabecular patterns correspond closely to the principal stress lines calculated in engineering. His method, called graphic statics, provided a visual way to map how forces move through structures.

This link between anatomy and engineering influenced nineteenth-century structural thinking. The same principle—placing material only where forces demand it—guided the development of lighter, more efficient frameworks in bridges, cranes, and reinforced-concrete designs.
