Presence and memorisation

A recent discovery in cognitive science reveals that ten seconds of silence after learning triples memory retention. This is not a mnemonic tip. It is an empirical confirmation of what I have been developing for several years in my philosophy of presence: to memorise is not to record, it is to be present to what one has just received.

A scientific fact that says more than it knows

Researchers have established this: when we learn something, whether a name, an idea, a path or a direction, the trace it leaves in our brain begins as a fragile electrical signal, an impulse that has not yet found its place in the neural architecture and which, in the first few seconds, hesitates between inscription and erasure, between consolidation and disappearance, as if the brain were asking, in its own way, the most radical question there is: is this worth existing? And every stimulus that arrives immediately afterwards — a sound, a screen, a gesture, any solicitation whatsoever — silently answers in its place: no, not important, erase.

By contrast, ten seconds of silence, eyes closed, with no new input, change everything. The group that practises this silence after each learning episode remembers, one hour later, three times more information than the group that moves on immediately.

Neuroscience may not be fully aware of it, but what it describes here, beyond synaptic mechanics and cerebral consolidation, is a philosophical phenomenon: the condition of possibility for any genuine integration of an experience — and that condition is presence.

Silence is an act

Contemporary physics, from quantum mechanics to particle physics, teaches us that matter is fundamentally vibratory: atoms, which compose everything that exists, are constituted almost entirely of void in oscillation, and the different chemical elements are distinguished from one another by the vibratory frequencies of their elementary particles. Alfred North Whitehead, in Process and Reality (1929), had already founded his process philosophy on this intuition: reality is not made of static substances but of vibratory events, of processes in perpetual resonance with one another. In this perspective, which I develop in my reflection on sound waves, our presence in the world is of an undulatory nature: we are, fundamentally, a vibrating mass present in a vibrating universe, and silence is never emptiness but one of the most intense modalities of being-there, for vibratory resonances are just as active in silence as in sound.

To make silence is an act, and it is even, often, a more demanding act than speaking or doing, because it requires accepting to be traversed by what one has just received, without protecting oneself from it through movement.

I experience this in my work as a group facilitator, and I observe it in a variety of contexts that far exceeds the scholastic or academic framework of memorisation: children in creative workshops, adults in professional seminars, elderly people in care institutions, families in mediation, groups in mental health settings, participants in cultural or recreational activities. In each of these situations, there is always that moment when someone has just articulated something important, when something has just been experienced, and when the collective reflex would be to move on, to respond, to fill the space. If I allow ten seconds of silence, something else happens. The group absorbs. The words take on a density they would not otherwise have had. This is not a facilitation technique. It is an act of collective presence, and it works in exactly the same way with a six-year-old child who has just drawn something powerful as with a senior executive who has just named a problem no one dared to voice.

What cognitive research describes as “memory consolidation” converges with what I call the time of resonance: the moment when what has just touched us settles into our vibratory interiority, imprints itself there, enters into dialogue with what we already are. Memory, understood in this way, is not a recording: it is a resonance.

Hartmut Rosa, in Resonance: A Sociology of Our Relationship to the World (2019), formulates this paradox: the attempt to guarantee the availability of things strips them of their quality of resonance. I often draw on this idea of Rosa’s in my reflections on anxiety and adaptation, because it says something very concrete: by wanting to access the next thing immediately, by saturating the moment that follows learning, we strip what we have just experienced of its capacity to transform us, we make it available on the surface and unavailable in depth, and we believe we are learning because we have been exposed to information, when we have quite simply not been present to that learning.

To memorise is an act of presence

Bergson distinguishes in Matter and Memory (1896) two forms of memory: habit-memory, which automates repeated actions, and pure memory, which preserves the singular, irreducible recollection of what has been truly lived. This second memory presupposes that experience has been received, not merely perceived. Yet to perceive without receiving is precisely what our era does at high speed: it multiplies exposures but makes receptions ever rarer.

This is what I observe in my work supporting individuals and organisations. People are exposed to a phenomenal quantity of content, training sessions, seminars, experiences of all kinds. And what genuinely remains from these exposures is often very little: not because the content was poor, nor because the people were inattentive, but because the exposure took place without reception being able to occur, because the fragile electrical signal was drowned out by the next stimulus before it had time to take hold.

But there is another mechanism, equally decisive, which the ten seconds of silence illuminate by contrast: the role of narrative. Paul Ricœur, in Time and Narrative (1983–1985), showed that our personal identity is constituted through the narration of what we live, and that it is through this narrative operation that the raw experience of time becomes human experience — that is, experience bearing meaning. What Ricœur calls narrative identity is precisely this capacity we have to tell ourselves what we have just been through, to step back from pure lived experience in order to fashion an inner narrative that will give it its place within our geography of presence.

Indeed, we do not live only in the immediate present: we also live in the narrative of our own lives, and this narrative is an act of presence in its own right. When we tell ourselves what we have just experienced, even silently, even in a still-formless way, we perform a work of symbolisation: raw experience settles into words, into inner images, it enters into resonance with what we already are, and it is in this resonance that what the experience means for us is revealed. The ten seconds of silence are perhaps, in this sense, the minimum time needed for this work of inner narration to begin — the operation through which we no longer merely perceive but start to receive, that is, to integrate experience into the narrative of what we are in the process of becoming.

This process of symbolisation is fundamental, and neuroscience research may be revealing its underlying mechanism without knowing it: when the brain consolidates a memory, it does not store raw data; it associates it with already existing networks of meaning, weaves it into a narrative fabric, gives it a place in what I call the geography of presence — that cartography of our inner states which varies according to contexts, the strata of our lived experience, what we have just been through.

Walter Benjamin had anticipated this distinction by differentiating Erfahrung — experience that sediments, that inscribes itself within a narrative continuity, that becomes wisdom — from Erlebnis — the lived event that leaves no lasting trace because it remains on the surface of consciousness as a shock without sequel and without narrative. In On Some Motifs in Baudelaire (1940), he diagnosed modernity as an era of generalised Erlebnis: events succeed one another, but nothing is integrated, nothing is narrated, nothing truly becomes experience. What the research on ten seconds of silence measures is exactly the possible passage from Erlebnis to Erfahrung, and this passage is effected by presence — a presence that is also, inseparably, the beginning of narration.

Closing one’s eyes, making silence after what one has just received, is not taking a pause in the sense of momentarily stopping before resuming the course of things: it is the act by which one decides that what one has just lived deserves to exist in itself, the gesture by which presence to what has just taken place allows it to be transformed into genuine experience — that is, into an event that finds its place in the narrative of who we are, in the geography of our presence, and that changes us, even imperceptibly, by the very fact of inscribing itself in us rather than sliding over the surface of our consciousness.

The time of presence is not clock time

I have posited, in my reflection on presence and time, an intrinsic link between presence and time, in reference to the link Einstein proposes between movement and time. Time is not an external flow that imposes itself uniformly on everything. Time dilates according to the movement of the subject. I have drawn a consequence from this for presence: presence is an intentional being, and this intentional being modifies the texture of lived time.

Merleau-Ponty puts it differently in the Phenomenology of Perception (1945): we are a body always already engaged in the world, in a pre-reflective relationship with what surrounds us. Memory is not an operation separate from the act of living. It is its inner extension, the way the world continues to work within us after we have encountered it.

This extension needs time — not chronological time, but qualitative time, the time of presence, what I have elsewhere called the capacity to create one’s own time: not submitting to it as an external continuum, but bending it to one’s intention of being, inhabiting it in depth rather than on the surface. The ten seconds of silence are not ten seconds on a clock. They are, provided one inhabits them, an inner duration that bears no common measure with the time of the diary.

It is here that the concept of geography of presence takes on its full meaning. Our presence to ourselves is not uniform: it varies according to contexts, the strata of our lived experience, what we have just been through. The same ten seconds of silence will not produce the same effect after an exhausting day in an open-plan office or after a walk in the forest. The geography of our inner journey conditions the quality of the welcome we are able to offer to what has just touched us.

Heidegger designated by Dasein that being-there characterised by its openness to the world, Erschlossenheit. This openness is not passive receptivity: it is the condition of all authentic understanding. To memorise, in the deep sense, is to understand in the Heideggerian sense: to let something take its place in our being-in-the-world, to imperceptibly alter the way we inhabit existence.

What we destroy by moving on

Research puts it bluntly: we destroy our memories when we move too quickly to the next thing. This verb deserves our attention. We do not simply lose information through inattention; we choose to destroy it. Every new stimulus that arrives immediately after a learning moment is an unconscious decision: this was not worth keeping.

I often think about this when I observe how the organisations I support operate. Meetings follow one another without transition. We shift from a strategic issue to a logistical problem in thirty seconds. We leave a creativity workshop and plunge into our emails. And then we wonder why nothing changes, why good ideas remain just good ideas, why decisions never take root. This is not a problem of willpower. It is a problem of presence. The insights did not have time to consolidate. The fragile electrical signal was drowned out.

Bernard Stiegler, in his reflection on tertiary retentions — those memories externalised in technical devices — showed how information technologies can both support and short-circuit our memorial capacity. The contemporary attention economy, with its notifications, its infinite feeds, its logic of “next”, is structurally organised to prevent those ten seconds of silence. It is a machine for destroying memories — for mass-producing Erlebnis without ever allowing Erfahrung.

This destruction affects not only our capacity to retain information, but our ability to be transformed by what we live. It is here that I return to the distinction I draw between being present and being merely exposed. An experience that is not integrated, that does not find its place in the narrative of our life, remains an event without sequel. It does not change us. It does not nourish our presence in the world.

Teleology of presence: Adler against determinism

There is, in this understanding of memorisation as an act of presence, a dimension that strikingly converges with the distinction between Freudian aetiology and Adlerian teleology. Freud, in his approach to the psyche, is concerned with causality: what happens to us is determined by our past, our traumas, our repressions, and therapeutic work consists in tracing effects back to causes. This is a powerful tool, and I do not discredit it in any way. But Alfred Adler proposes a complementary perspective and, in my view, a more operative one for thinking presence: teleology — that is, the study of a phenomenon’s purpose rather than its cause.

Where Freudian aetiology asks “why am I this way?” and seeks the answer in the past, Adlerian teleology asks “what am I moving towards?” and seeks the answer in present intention, in the capacity for action that we have now, here, in this precise moment. Ichiro Kishimi and Fumitake Koga, in The Courage to Be Disliked (2013), which presents Adler’s thought in the form of a living philosophical dialogue, express this very clearly: we are not determined by our past experiences, but by the meaning we give them now and by the goals we set for ourselves in the present.

This connects very deeply with my conception of presence. If our memory depends on our capacity to be present to what we receive, then it is not a mere imprint of the past upon us: it is an act of our presence in the present, oriented by our intention, by what we want to become, by the direction we give to our existence. In Adlerian terms, to memorise is a teleological act: it is not the past that determines what we retain; it is our intentional presence in the moment that decides what deserves to inscribe itself in us. And silence, the ten seconds of silence, are precisely the space where this decision, most often unconscious, can occur: not the repetition of a past that would determine us, but the opening of a future that transforms us.

Seen from this angle, the opposition between Freudian determinism and Adlerian teleology is not a war of doctrines but a question of stance towards our own life. Aetiology helps us understand, and that is precious. But teleology gives us a power to act: the power to decide, in the present moment, what will matter for us, what we will allow to inscribe itself, what we will be present to. When Adler refuses to reduce the human being to a dictatorship of the past, he opens a space that is exactly that of presence as I conceive it: not a self-absence predetermined by our history, but a capacity to be there, fully, in the very act of receiving what comes.

An ethics of learning

There is, in this small gesture — closing one’s eyes, breathing, letting the brain keep what it has just worked on — an ethics whose scope far exceeds mnemonics. It is the affirmation that learning is not consumption, that an idea received is not an idea integrated, that knowledge is not accumulation but transformation.

Dewey called this the difference between education and mis-education: a genuine education is one that increases our capacity to be affected by experience, to draw real growth from it. A pseudo-education exposes people to content without allowing its integration, producing the illusion of knowledge without its substance.

I find here, from an unexpected angle, what I explored in my reflection on absence at the point of blockage. When we cannot manage to change, to integrate what we nonetheless know, it is not always a problem of knowledge or willpower: it is sometimes a problem of presence — we were not present at the moment when learning could have inscribed itself in us; we were already elsewhere, already in the next thing, already fleeing the silence that would have allowed us to receive.

Presence and memorisation are not two parallel phenomena. Authentic memorisation is an act of presence. It presupposes that one has accepted, for at least a few seconds, to do nothing other than be with what one has just received. This is not efficiency in the productivist sense. It is efficiency in the existential sense: letting something take place within oneself.

In an era where everything is designed so that nothing has time to take place, this ten-second silence is an act of resistance. Perhaps even, at the scale of each learning moment, a political act.

This concept is part of the philosophy of presence developed in these pages, and echoes the reflections on time, resonance, attention, the geography of presence and sound waves proposed here.
