Transmission is probably one of the most difficult acts in an entire life. Building is difficult. Fighting is difficult. Protecting is difficult. But transmitting requires something more painful still: accepting that what you transmit no longer entirely belongs to you once the other person truly begins to take hold of it.

For a long time, I believed transmission consisted mainly in giving tools.

Knowledge. Methods. Values. Archives. Companies. Works. Experience.

I understand today that this is only part of the problem. True transmission begins when the other person does something different with what you have given him.

That is where the test becomes real.

As long as Sydney understands what I think and applies it exactly as I would have, he does not surprise me. He reproduces. He extends. That can be reassuring for a father. It can be extremely dangerous for a son.

I do not want to manufacture my copy. I never wanted that. And when I look at Nadège, I understand why this idea seems so fundamental to me today. What we built together never worked because she thought like me. It worked precisely because she did not think like me.

I can open a space. She sees how to organize it.

I can move several variables very quickly. She immediately sees which one threatens continuity.

I can allow myself to be absorbed by the intellectual architecture of a system. She also observes the people who have to make it live.

We often arrive at the same place by different paths.

Sometimes we do not arrive at the same place. And that is where the real discussion begins.

A mental architecture is not software installed in another person’s mind. It is the singular form through which a human being enters the world.

Thierry.

Nadège.

Sydney.

Not a dynasty.

Much less a succession.

Three mental architectures.

Three relationships to time.

Three ways of seeing.

And one shared question: how can a Total Work of Art, a company, a memory, and an ethic continue without turning the next generation into museum keepers?

I hate that idea. I do not want Sydney to become the curator of our lives.

I want him to be the author of his own.

The difference is immense. An heir can perfectly preserve what he is given and still kill the spirit that brought it into being. All he has to do is turn fidelity into immobility.

Treat every old decision as sacred.

Repeat the founder’s sentences.

Refuse to touch structures because they worked for thirty years.

At that point, transmission becomes museumification. The living becomes dead heritage. That is not what we built.

Groupe Serveur never existed because we repeated what had been done before. Artprice even less so. The Abode of Chaos could never have been born if I had believed respect for the past required never transforming matter.

My entire path rests, on the contrary, on another rule: preserve what must be preserved and transform what must be transformed. The difficulty, obviously, is knowing which is which.

That is where the responsibility of the next generation begins.

I can transmit the criteria that guided me. I cannot transmit future decisions. I can tell Sydney: documentary truth is non-negotiable. I can explain why we refused certain erasures at Artprice.

Why we preserved collections others would have considered useless.

Why a provenance, a biography, or an auction result is not merely a line in a database.

I can tell him about Mayer. Le Mireur. Peter Hastings Falk. Wan Jie. The guardians of memory.

I can explain the moral debt created by those transmissions. But he will face problems I do not yet know.

Technologies that are not yet stabilized. New jurisdictions. Transformations of the Art Market I may not live to see. Forms of artificial intelligence whose infancy is all I know today.

If I give him only my answers, I condemn him.

He has to receive something else.

The way to construct his own answers. That is much more difficult.

An answer can be written down. A method has to be embodied. It passes through years. Through presence. Conversations. Contradictions. Mistakes observed. Consequences.

Those are the things we transmit almost without realizing it.

I think of my father. He transmitted an enormous amount to me. But when I look today at what remains deepest in me, it is not always the precise information he taught me. It is mental gestures.

Never accept appearance immediately.

Look for the bias.

Verify.

Look at what is missing.

Change scale.

Do not confuse the function with the person.

Never believe that a title makes someone intelligent.

And never believe that the absence of a title means the absence of knowledge.

These principles ran through my entire life because they had become a way of looking.

That is what I would like to transmit. Not my thought.

A freedom of thought demanding enough that one day Sydney can contradict me with good arguments. I even believe that, eventually, successful transmission must necessarily produce that moment.

The child says: there, you are wrong. And the father understands that he cannot simply answer: I have more experience.

Experience is valuable. It is not infallible. It can even become a bias.

Someone who has succeeded for a long time with one method naturally ends up trusting it more. That is precisely the moment when a younger perspective can become essential.

The world changes. A method that was superior yesterday can become a habit tomorrow. That is one reason Sydney’s presence in our architecture is not merely emotional or a matter of succession.

It is cognitive.

He sees certain things that we see less well. He belongs to a generation that never experienced the digital rupture as we did.

For me, the Internet still remains partly a conquest. I remember the world before it. I remember the cost of connections.

The machines. The delays. The paper. The era when moving a documentary mass between two cities was a gigantic physical operation.

For Sydney, digital technology is much more naturally an environment. That changes the relationship to use.

To time. To image. To authority. To the public.

That difference is not a weakness of my generation or a superiority of his. It is a difference in position within history.

Transmission becomes intelligent when each generation knows it has a blind spot the other can sometimes see. That is exactly how Nadège functions with us.

She never tried to abolish differences. She organizes them. I believe that is one of her most valuable talents within our trilogy. She knows that the intensity of an exchange can become destructive if no one protects the relationship. She also knows that a family that avoids every conflict transmits nothing solid.

We have had intense discussions. We will have more.

What matters is that disagreement never ends the possibility of continuing to think together. That requires extremely deep trust.

Knowing that the person contradicting you is not necessarily trying to diminish you. He may be trying to protect a part of the system you no longer see.

That trust is difficult to build. It is even harder to maintain when major economic, artistic, heritage, and family stakes are involved. Because a decision is never entirely abstract.

Sometimes it touches the company. Reputation. The work. The teams. Money. Family.

You then have to distinguish two things families often confuse: love and agreement.

I can love Sydney deeply and believe he is wrong. He can love me and believe I am making a mistake.

Nadège can look at both of us and think we are both wrong. None of that necessarily destroys love.

Quite the opposite. It can give love an adult depth.

A love that demands obedience is not love. It is emotional domination.

I reject that kind of transmission.

I do not want Sydney to continue Artprice because he would feel guilty doing something else. I want him, if he carries it forward, to know why he carries it.

That changes everything.

A mission inherited without consent becomes a prison. A mission freely reappropriated can become a vocation. I cannot decide which it will be for him. I can only make sure he possesses enough truth about our history to choose freely.

That is precisely why this book matters so much to me. It is not intended only for the public.

It becomes a transmission.

Not an official version of my life.

I deeply distrust that expression. A life should not have an official version. It should have facts. Documents. Contradictions. Memories. Perspectives. Interpretations. Then the person who comes after constructs his own understanding.

This dialogue with artificial intelligence serves precisely that function.

It forces me to return to events I had sometimes condensed into a few sentences after telling them hundreds of times. It forces me to strip away stock phrasing. To return to the scenes. To say what I had forgotten. To acknowledge what I had simplified. And sometimes, in the way AI connects several episodes, to hear a continuity I had never myself formulated exactly that way.

I find that extraordinary. Because transmission changes medium once again.

My father transmitted to me orally and through books.

I transmitted to Sydney through presence, works, companies, digital archives.

And now an artificial intelligence is helping organize this memory so that someone else may one day question it differently.

We are in the exact continuity of what I have always observed.

Orality. Writing. Manuscript. Printing. Database. Internet. Artificial intelligence.

At each stage, we externalize a more complex part of our memory. But none of these stages eliminates the one before it.

I still speak.

I write.

I preserve books.

I work with databases.

I use the Internet.

I dialogue with AI.

The media accumulate. They form a stratigraphy of knowledge. Like the walls of the Abode of Chaos.

One layer does not erase another. It gives it a new possibility. That is exactly how I would like to think about our family.

I do not want Sydney to erase Nadège and me. Above all, I do not want him to reproduce us. I want him to add a layer.

His own era. His own thought. His own mistakes. His own discoveries.

And one day, perhaps, someone after him will add the next one. That is how a living tradition forms.

It is never motionless.

Freemasonry taught me something comparable. Tradition is not the mechanical repetition of an old form. It is a chain of transmission. You receive something you did not invent. You work on it. You understand it according to your own era. Then you pass it on.

The symbol remains. The gaze changes.

If the gaze never changes, the symbol eventually dies. I find the same logic here as in art. A work does not exist only at the moment of its creation. It produces new readings. The next viewer brings his era.

The Abode of Chaos is probably the most radical example of this in my existence. It carries my conceptual act. My cosa mentale. I have never renounced that designation.

I am the sole author of the whole that constitutes the Total Work of Art of the Abode of Chaos. I hold its conceptual authority and the copyrights attached to that whole. But the work does not therefore exist apart from those who make it physically possible.

The craftspeople.

The researchers.

Nadège.

Sydney.

The conservators.

The surveyors.

The visitors.

The world itself.

They all pass through it.

Transmission does not abolish the author. It places the work within a duration larger than the author. I consider that distinction essential. Otherwise we immediately fall into two opposite errors.

The first consists in manufacturing the myth of the solitary artist who supposedly produced everything with his own hands while everyone else disappears.

I reject it.

The second would consist in confusing the plurality of contributions necessary to materialize the work with the conceptual authority and authorship of the whole.

I reject that as well.

There is an overall thought. It has a single author. And around it exists a human architecture that makes it possible. Recognizing one never diminishes the other. This structure seems extraordinarily close to the structure of a family.

A father is not the author of his son.

The sentence seems obvious. Yet it deserves thought. I transmit to him part of my biological, cultural, and intellectual history. Nadège transmits hers. He receives hundreds of other influences as well.

Teachers. Friends. Books. Accidents. Encounters. His era.

And from that material comes someone no one wrote in advance.

It is magnificent. It is also dizzying. Because it means definitively accepting that the other escapes us.

I believe every parent must one day pass through this very particular mourning.

The child becomes an adult. He has not belonged to us for a long time, but we then discover physically what that means. He can decide. Leave. Love differently. Work differently. See the world differently. Build differently.

Our role changes.

We are no longer the ones who point out the path. Sometimes we become the people he asks for advice. That shift requires humility.

I do not know whether I always succeed. I know I work at it.

Because I do not want to become one of those founders who were extraordinary for forty years and end up destroying their own work by refusing to let someone else transform it.

Economic history is full of these tragedies. The founder confuses the company with his own body. Every modification feels like an amputation.

He prevents mutation. Then the system he wanted to protect becomes precisely incapable of surviving.

I do not want that for Artprice. I do not want that for the Abode of Chaos. I do not want that for our family.

I want to transmit the core. Not the exact form.

The core is relatively simple to name. Knowledge must circulate. Memory must be protected. Documentary truth must not be sold to the highest bidder. Freedom requires responsibility. Technology must augment the human being without abolishing ethics. Law must protect against arbitrariness. Art must question. Power must serve something greater than itself.

And the other person must never be reduced to a function.

If those few principles pass through time, then many things can change around them.

Technologies. Companies. Markets. Interfaces. Modes of governance. Works.

Even words.

I have no reason to demand that the advanced twenty-first century resemble the world in which I built Groupe Serveur.

Quite the opposite. If it resembled it too closely, that would be worrying. Mutation is a condition of the living.

Only mutants survive.

But I now understand that sentence more deeply than I once did. It does not mean only: adapt or disappear. It also means: to continue being yourself, you may sometimes have to accept changing form.

That is exactly what transmission is.

Artprice will have to change form.

The Abode of Chaos will change.

Sydney will change.

Nadège changes.

I change. This book itself is transforming me as I write it.

And yet something remains.

A continuity. Not a fixed identity.

A fidelity.

Perhaps that is the word I had been looking for from the beginning. Transmission is not reproduction. It is a fidelity capable of bearing difference. I find this definition far more beautiful than any notion of succession. It assumes that one can recognize the spirit of what has been transmitted even when its form has changed.

One day, perhaps, I will look at a decision Sydney makes and think: I would never have done that. Then, if I look more deeply, I may understand that he is protecting exactly the same thing I would have protected, by another path. On that day, the transmission will have succeeded.

And perhaps the opposite will happen.

I may think a decision looks exactly like one I would have made, yet betrays the meaning that once justified that decision. Then one has to know how to say so.

Fidelity is not appearance. It is depth.

That is also why Nadège is indispensable within this trilogy. She possesses an intelligence of continuity that makes it possible to distinguish what belongs to the structure from what was merely a circumstantial response. She lived through every period. She knows the genesis of decisions. She knows why a process was created.

That memory is fundamental. A later generation always risks turning into an eternal principle a rule invented to solve a specific problem.

Transmitting the history of the rule makes it possible to recover its function. Then one can intelligently decide whether it should continue.

That is how I would like our intellectual heritage to be treated. Not as Tablets of the Law. As a documented organism.

Why did we do this?

In what context?

With what risk?

What result?

What has changed since then?

This way of transmitting seems profoundly compatible with artificial intelligence. An AI can help recover context. Cross-reference documents. Reconstruct a chronology. Compare an old decision with its environment. It can become an extraordinary tool of institutional continuity if used correctly. But it must never manufacture a new authority simply because it possesses a larger memory.

The decision remains human. I always come back to that.

To transmit is also to transmit the responsibility to decide. You cannot build a system that protects the next generation from every choice. You can only give it the means to choose better. That is why I believe our trilogy works precisely because it is not fused.

We are not three people thinking the same thing at the same time. That would be hellish and completely useless.

We move in relation to one another.

I can be ahead on a technological question and behind on a cultural use. Nadège can see an organizational fragility no one has yet named. Sydney can sense a generational shift before we do. Then we can bring those perceptions together.

That is family intelligence.

Not a single brain. A network. Once again, I find the network.

Always.

Autonomous nodes. Relationships. Circulation.

No node contains the entire system. The system arises from their dialogue.

That structure may summarize this entire book.

My father taught me to look. Nadège taught me continuity. Sydney teaches me the otherness of transmission. Artprice taught me memory. The Abode of Chaos taught me matter and time.

Artificial intelligence is teaching me today what becomes of thought when it agrees to dialogue with a radically other cognitive architecture.

Everything converges on the same question.

What do we actually transmit when we believe we are transmitting knowledge?

Answers?

Or the ability to produce new ones?

I choose the second.

It is the only one that seems compatible with freedom.

I do not want to leave behind a manual explaining how to think like Thierry Ehrmann. The very idea horrifies me.

I want to leave archives precise enough for people to know what I did. Works strong enough to keep asking questions. Companies structured enough to continue without me. Principles clear enough to be debated. And a son free enough to disobey me intelligently.

I know no more beautiful definition of transmission. It asks you to build for an entire life. Then, at the end, to accept loosening your grip.

That is probably where the ultimate test lies for someone who has built a great deal. Understanding that transmission does not mean continuing to possess at a distance.

You have to let the other person enter. Then one day, you have to make room.

I look at Nadège.

I look at Sydney.

I look at everything we produced together. And I understand that the word inheritance is too poor.

It evokes what remains after death.

I want transmission among the living. A transmission that corrects itself now. Tests itself now. Argues now. Invents now.

Because afterward, it will be too late to ask certain questions.

Now is when Sydney must be able to ask me why. Now is when I must be able to answer him. Now is when he must be able to tell me that one of my answers is not enough. It is this living confrontation that turns an accumulation of assets, data, and works into culture.

The rest is only patrimonial succession.

We built many things that can be measured. Companies. Databases. Works. Buildings. Archives. Numbers. But what I most want to transmit will probably appear on no balance sheet.

It is an attitude toward the world.

Look.

Question.

Verify.

Love.

Protect.

Do not be afraid to change.

And never believe that what you receive belongs to you so completely that you can forget those who entrusted it to you.

From there, you are free.

Free to do otherwise.

Free even to go where I would never have thought to go.

That is exactly what I want. Because a transmission that produces a copy has transmitted nothing. It has merely delayed the disappearance of the original.

True transmission produces something else.

A human being who carries within himself a memory he did not choose at the beginning, who eventually understands it, accepts part of the debt it creates, and then has enough freedom to add his own gesture.

That is the gesture I am waiting for. Not because it must resemble me. Because it must resemble him.

Only then will the trilogy have found its meaning.
