THE BIRTH OF AN IDEA
The Brain of Presence: The mind does not unfold in a vacuum.
From birth to the end of life, presence silently shapes our development, our balance, and our way of inhabiting the world.
We have all had this experience.
Entering a room alone.
An office.
A silent corridor.
A house.
Then to feel that someone is there.
Sometimes even before seeing it.
A noise, a shadow, a vague impression — nothing certain, and yet already something.
Immediately, something changes.
Attention is being reorganized.
The body becomes slightly more alert.
The perception of space is no longer quite the same.
As if the brain were already adjusting its functioning, without waiting for certainty.
Are we alone… or not?
The question is rarely posed in such stark terms. Most of the time, it has no clear answer — only a degree of certainty, which sharpens or fades as new clues appear.
This experience seems ordinary.
And yet, it may reveal something far deeper.
For over a century, numerous studies have shown that the mere presence of other people can already modify our behavior, our attention, our level of effort, or our performance.
This phenomenon, known as social facilitation, is one of the oldest and most robust observations in experimental psychology.
The presence of others sometimes seems to help us mobilize more of our resources.
At other times, it increases hesitation or difficulty.
But in both cases, one thing already appears clearly: we don't function in quite the same way when someone else is present.
This observation began to resonate across very different fields: psychotherapy, human development, trauma, attachment…
Everywhere, the same intuition seemed to resurface: Some presences foster inner security. Others keep the nervous system durably in a state of vigilance or anticipation of danger.
Gradually, another question began to emerge.
What if the presence of others didn't only shape our relationships, but already the very conditions in which the brain functions?
It was from this intuition that the Brain of Presence project was born.
An attempt to explore a simple question:
What if the human brain was never designed to function truly alone?
What presence may already be changing in your life
Take a moment.
And observe.
Do you work the same way when someone is present? Do certain people immediately soothe your nervous system? Have you ever felt that a place "changed" simply because another person entered it? Do you think more clearly in some presences… and less clearly in others?
Do certain absences continue to act long after others have left?
Perhaps we tend to look at these phenomena as secondary, subjective, or simply emotional.
And yet, they may already reveal something deeper: the way in which the presence of others silently participates in the organization of our mental life.
If several of these questions resonate with you, then you may have already encountered, in your own experience, what the Brain of Presence seeks to explore.
