Strange Loops

Piranesi's Carceri Plate VII – The Drawbridge, (1745, reworked 1761)

I can identify the first moment I became aware of consciousness itself.

I was crouched in the dirt outside our house in Shearwater. The ground was cool from the coastal air. Pebbles pressed into my knees and hands. I could smell salt, though the water was out of sight. The afternoon was quiet. Sunlight fell evenly across the road, the neighboring houses, and the patches of grass between them.

I remember looking.

The road.

The sky.

My hands.

Then a single thought appeared.

Again.

The word arrived before I understood it. It carried an odd sense of familiarity, as though I were recognizing something I had always known without ever putting it into language. I was too young to think much about time. Life consisted of mornings, birthdays, summers, Christmases. Yet everything around me seemed strangely familiar in a way that reached beyond ordinary memory.

It felt as though I had arrived in the middle of an ongoing story.

The street already belonged where it was. The sky did too. Even my own existence carried that feeling. I wasn't discovering the world. I was re-entering it.

What surprised me wasn't the scene itself. It was the familiarity.

Children sometimes describe experiences that resemble déjà vu. This felt related, though broader. The feeling wasn't tied to one event. It seemed woven into experience itself. Reality carried a quiet sense of recurrence.

Years later I came across Friedrich Nietzsche's idea of eternal recurrence.

Imagine living your entire life over and over again. Every conversation. Every mistake. Every joy. Every ordinary afternoon. Nothing changes. Everything returns exactly as before.

Nietzsche's question wasn't about cosmology. It was about affirmation. Could you embrace your life completely if you knew you would live it forever?

I found the idea both fascinating and unsettling.

Then something clicked.

That childhood memory came back to me.

Recurrence already fills much of human life.

Our hearts beat in repeating rhythms. We breathe the same way from infancy until death. Habits become character. Families pass patterns of behavior from one generation to the next. Seasons return. Stories survive because each generation retells them. Even change usually builds on what came before.

Nature is full of cycles.

Science encounters them everywhere. Living organisms maintain themselves through continuous feedback. Ecosystems depend on recurring exchanges of energy and matter. The brain constantly updates its picture of the world while monitoring its own activity.

The more complex a system becomes, the more often it seems to refer back to itself.

Mathematics offers a striking example.

In the twentieth century, Kurt Gödel showed that sufficiently powerful formal systems can produce statements about their own structure. Arithmetic begins as a way of counting. Eventually it becomes capable of examining its own foundations.

Something similar happens in philosophy.

We begin by asking questions about the world. Before long we ask how knowledge works. Then we ask what it means to ask questions at all. Eventually the investigator becomes part of the investigation.

Many thinkers noticed this pattern. Hegel explored it in history and reason. Jung found it in psychological development. Whitehead described it as part of the process of reality itself. Douglas Hofstadter examined it through mathematics, art, and cognitive science.

Consciousness has an unusual property. It can become aware of itself.

That simple fact gives rise to the experience we call "I."

The word seems ordinary. The history behind it is anything but.

Over billions of years, matter organized into living organisms. Living organisms developed nervous systems. Nervous systems supported memory. Memory made narrative possible. Narrative gave rise to personal identity. Eventually a creature appeared that could ask why the universe exists and why it is able to ask the question.

Art has explored this movement for thousands of years.

A melody returns to its opening phrase after everything that has happened in between. A novel ends where it began, yet the reader understands that place differently. Ancient stories often conclude with a return home.

Odysseus reaches Ithaca.

The Buddha returns to ordinary life after enlightenment.

Dante looks once more upon the earth.

The destination matters. So does the return.

Over time, my memory from Shearwater took on a different meaning.

For years I treated it as an unusual childhood experience. Now I see it as part of a broader feature of consciousness.

We often imagine understanding as climbing upward. Knowledge accumulates. Perspective expands. Wisdom sits somewhere higher than where we started.

That image works well enough.

But many forms of understanding are circular.

Imagine walking uphill through a coastal town. With every street, the view grows wider. The rooftops give way to the harbor. Beyond the harbor lies the open sea.

Eventually you reach the top.

You look back.

The same street is still there.

Children are still playing.

Light still falls across the same windows.

Nothing has changed.

Everything has changed.

The place is familiar, but you now see it within a much larger landscape.

Life often works this way.

Books reveal ideas that escaped earlier readings. Places from childhood look different when we revisit them as adults. Music we have heard for decades suddenly reveals patterns we had never noticed.

The world stays remarkably consistent.

We are the ones who change.

Meaning accumulates through repeated encounters.

Henri Bergson argued that time has depth. The past does not disappear. It remains active in the present, shaping each new moment through memory and experience.

Perhaps that explains why the word again carried such weight for me as a child.

By the time we become conscious of ourselves, our brains have already spent years learning patterns. Every new experience arrives against the background of countless earlier ones. Recognition is built from repetition.

Standing outside our house in Shearwater, I knew none of this.

I knew gravel.

I knew sky.

I knew my hands.

And somehow I knew that everything before me possessed the feeling of return.

Whether that intuition pointed toward some deeper truth matters less to me now than it once did.

What remains is the observation that consciousness grows through revisiting the world. Identity develops through repetition. Meaning gathers slowly around the people, places, and ideas we encounter again and again.

The path forward often bends back toward where we began.

The beginning is rarely left behind.
