Do Humans Change, or Do They Adapt?

Preamble: the innate, the acquired, and the conditions of existence#

A large part of the modern view of the individual rests on an implicit idea: that each of us is, fundamentally, the primary author of ourselves. We only need to want, choose, and work on ourselves in order to become someone else. This way of thinking gives enormous weight to individual will, merit, personal responsibility, and the supposed ability of each person to transform themselves through decision alone.

But that picture breaks down as soon as we return to a simple fact: a human being is not born into a void.

At birth, every individual is given something innate: a set of dispositions, sensitivities, potentials, and limits that exist prior to experience. The innate is not yet a fully formed person. It is better understood as a field of possibilities.

From there, what we call the acquired gradually takes shape. And the acquired does not fall from the sky. It is built through concrete conditions of existence: the family environment, material security, emotional stability, access to language, the habits of the household, the quality of relationships, social position, cultural resources, local norms, hardships encountered, and support received.

In the first years of life, the individual has almost no control over any of this. They do not choose their family, their social environment, or the degree of physical and emotional security in which they grow up. They depend deeply on a system that is already there: an entourage, a culture, a material organization of the world, a structure of social relations.

In other words, the acquired is formed largely under conditions that are not initiated by the subject. The development of an individual depends both on what their innate dispositions make possible, and on the way their conditions of life allow — or prevent — the realization of that potential.

From that point on, it becomes possible to challenge overly simple views of merit. What a person becomes over time depends on an accumulation of very different forms of capital: emotional capital, material capital, cultural capital, social capital, symbolic capital, and sometimes physical capital as well. All of them give a person more or less leverage over the world. A human trajectory is never simply the product of an isolated will.

The real question: do humans really change?#

From this observation, another question emerges.

If the human being is so deeply conditioned by the conditions of existence, can we still say that they change? Or should we say something more precise: that they adapt?

The thesis defended here is the following:

Human beings do not directly change themselves. They adapt. What they can sometimes change, however, are some of the conditions of their lives. And it is then adaptation to those new conditions, over time, that transforms them.

This distinction matters.

To say that an individual changes can suggest that all they need to do is decide to become different in order to become so. As if inner transformation could be immediate, commanded, voluntary, almost mechanical. As if a person could say, “starting today, I am different,” and that statement alone would be enough to produce the metamorphosis.

But that is not how living beings work.

Changing one’s conditions is not yet changing oneself#

A human being can make certain punctual decisions. They can begin a physical practice. They can move. They can change their schedule. They can change their social circle. They can leave a destructive job. They can expose themselves to more light. They can reorganize their living space. They can decide to read more, go out more, slow down, train, rest, or meet new people.

All of this does involve change — but it is a change in conditions, practices, setting, rhythm, or environment.

What it does not do is instantly transform the individual themselves.

Exercising today does not mean becoming a different body today. Starting to read does not mean immediately becoming a different mind. Leaving a stressful environment does not mean instantly recovering a calm nervous system. Changing one’s social milieu does not mean adopting new dispositions on the spot.

Between a modification of conditions and a transformation of the subject, there is a time of adaptation.

And that is precisely where the core of the issue lies.

Adaptation: a slow, situated, embodied process#

Adaptation is not an event. It is a process.

It unfolds over time. It depends on repetition, exposure, maturation, thresholds of tolerance, prior history, each person’s particular vulnerability, the nature of the demands placed on them, their intensity, their frequency, and their coherence.

The body does not transform itself by decree. Neither does the psyche. Habits, emotions, reflexes, modes of perception, ways of relating, and capacities for attention or recovery do not reconfigure themselves instantly.

They reorganize themselves gradually, as the living being encounters new conditions and learns — or is forced — to inhabit new ways of existing.

That is why it is more accurate to say that an individual adapts than that they change themselves.

The expression may sound more modest, but it describes reality far better.

The body makes this especially clear#

The body is probably where this truth appears most clearly.

If someone begins physical training, the body does not immediately become stronger, more enduring, or more stable. It enters into a process of adaptation. Muscles, the cardiovascular system, sleep, recovery, coordination, energy, and tolerance for effort all evolve progressively.

The same is true in the opposite direction. An environment of chronic stress, sedentariness, noise, hyperstimulation, lack of rest, or emotional insecurity also produces adaptations. The nervous system recalibrates. The body develops responses. It learns certain tensions. It internalizes certain rhythms. It prepares for certain dangers, sometimes even when those dangers are no longer present.

In other words, the body does not freely choose what it becomes. It responds, adjusts, compensates, absorbs, and reconfigures itself. It adapts to what is demanded of it, to what it is exposed to, and to what it must endure.

And the mind, far from being separate from the body, follows much the same logic.

The mind adapts too#

We often like to believe that psychic life is freer, more directly governable. Yet here too, the most real transformations pass through duration.

A new intellectual practice gradually modifies the way the world is ordered. A new social environment gradually modifies the way one speaks, judges, compares, and projects oneself into the future. A secure relationship gradually changes the way one loves, trusts, inhabits silence, and tolerates uncertainty. A stable routine gradually changes attention, inner availability, and quality of presence.

Conversely, some conditions of life can produce defensive adaptations: hypervigilance, inhibition, fatigue, withdrawal, avoidance, a need for control, difficulty concentrating, a narrowing of one’s field of existence. Here again, this is not always the result of a conscious choice. It is often a way for the organism to hold together within a given frame.

What we sometimes call “personality” therefore contains a significant share of embodied history.

Some experiences transform us through adaptation#

This logic becomes especially visible in certain long and intense life experiences.

We can think first of long journeys, and more particularly of pilgrimages such as the Camino de Santiago. Many people say, when they return, that the journey transformed them. And there is no reason to deny the truth of that experience. But what that formula usually points to is not a sudden metamorphosis of the self. It is the fact of having lived, for weeks or months, within another regime of existence: walking every day, carrying little, meeting strangers, experiencing fatigue, solitude, slowness, simplicity, repetition, and sometimes silence. By abruptly changing one’s frame and then remaining in it long enough, the individual adapts to another way of life. And that prolonged adaptation transforms them.

The same thing can happen in illness, and then in recovery. When a person goes through a long illness, or a period of deep fragility, they are often forced to modify their rhythm, their priorities, their relationship to the body, rest, others, performance, fear, and even time itself. If that situation lasts, it produces adaptations. Then, when recovery begins, further adaptations may emerge. The person sometimes feels that they are discovering themselves differently, revealing themselves to themselves. But what is happening is often more concrete than that: another mode of existence imposed itself, and was inhabited long enough for other dispositions, other needs, and other ways of feeling and living to emerge.

The same holds true in durable relationships. A deep friendship, a love, a shared life, a constant presence, repeated support — or, on the contrary, a relationship marked by insecurity — can profoundly transform an individual. Not in a day, but through prolonged exposure. By being repeatedly welcomed, listened to, supported, contradicted, hurt, reassured, or expected in a certain way, one adapts. Little by little, one learns other reflexes, other forms of trust, other forms of caution, other impulses. Here again, what is sometimes called personal transformation is often a slow adaptation to a relationship that has become structuring.

These examples all have one thing in common: they show that some life experiences do not transform us only because they leave a psychological mark, but because they modify our conditions of existence for long enough that body, mind, habits, and expectations have time to reorganize themselves.

We can decide on the frame, not on the exact outcome#

This is where the strongest point of the thesis appears.

Even when an individual voluntarily changes their conditions of life, they do not fully control the outcome of the adaptation that follows.

They may decide to bring more light into their home. They may choose a calmer job. They may return to a life that is more physical, more social, slower, or on the contrary more stimulating. They may distance themselves from harmful situations. They may create a new frame.

But they do not know with certainty, at the moment they make that change, exactly how their body, their nervous system, their attention, their emotions, their desires, their fatigue, or their relation to the world will reorganize themselves.

They know that a displacement of the frame will have consequences. They do not know the precise form the adaptation will take.

That is why the idea of “changing oneself” is misleading.

We can sometimes choose causes. We do not directly choose all of their effects.

Will still plays a role, but a limited one#

This thesis does not say that the human being is entirely passive.

A person still retains some initiative. They can act on certain parameters of their existence. They can leave, begin, interrupt, organize, build, protect, search, and try. They can create more favorable conditions or, on the contrary, remain trapped within certain constraints.

But that initiative should not be overstated.

First, because it is always situated: we never act from a neutral point. Our real possibilities depend on our resources, our health, our age, our milieu, our obligations, our history, and our degree of autonomy.

Second, because even when a margin of action exists, it applies first to the frame, far more than to the immediate transformation of the self.

Will can displace certain elements of lived reality. Adaptation will then do its work over time.

Another way of thinking about change#

To say that human beings do not change, but adapt, does not mean that they never evolve.

It means something more precise:

• human development is real;
• but it is not instantaneous;
• it is not directly commanded by will;
• it passes through repeated exposure to certain conditions;
• it depends on time, the body, history, and context;
• and its exact outcome remains partly unpredictable.

Seen from this angle, what is usually called “personal change” looks more like a simplified name for a deeper phenomenon: a slow, embodied, situated transformation, triggered or oriented by modifications in one’s conditions of life.

In that sense, if one wants, one can still say that human beings change — but they change through adaptation. And if one wants to be more rigorous still, one should say this:

human beings do not directly change themselves; they sometimes modify some of their conditions of existence, and are then progressively transformed by adaptation to that new frame.

Consequence: a critique of the all-powerful individual#

This way of seeing things has an important consequence. It invites us to distrust discourses that attribute excessive power to the individual over themselves.

Calls to “become the best version of yourself,” to “reinvent yourself,” to “decide who you want to be,” or to “succeed through willpower alone” often rest on a deep misunderstanding of how human beings are actually formed.

They forget that the living being has inertia. That it has memory. That it has history. That it needs time. That it depends on a milieu. And that this milieu often weighs far more than the slogans of self-mastery.

Thinking in terms of adaptation allows us, by contrast, to recover a more accurate, more concrete, and more embodied view of human existence.

Conclusion#

Human beings are born with an innate endowment, and then formed through acquisitions shaped by their conditions of existence. Since they do not choose those conditions in the first years of life, a decisive part of what they become is built before they can exercise any real initiative.

Later on, they may sometimes modify certain dimensions of their frame of life. But they do not directly decide what they become. Between the change in conditions and the transformation of the individual, there is always that intermediate, decisive, irreducible time: the time of adaptation.

That is why it is more accurate to say that human beings do not change themselves in the strong sense. They change indirectly, and often only partially, by adapting to conditions they first undergo, and that they may later, in part, rearrange.

The central lesson of this thesis may be this:

we do not create ourselves ex nihilo. We become what our conditions of life gradually make possible, and what our organism slowly learns to inhabit.
