The protocol presents itself as an immaculate square. A place where voices, reduced to cryptographic signatures, intersect without the weight of flesh, without the geography of the body, without the history written on a face. It promises an ancient purity: mathematical certainty instead of wavering trust, a horizontal network instead of a hierarchical tower, autonomous identity instead of a bound subject. Nostr is not just a technical tool; it is the latest, extreme incarnation of a centuries-old philosophical dream. The dream of separation. Of the mind freeing itself from the ballast of the body, of the subject rising as a neutral observer and master of an object-world. It is the dream that Descartes sealed in the “cogito ergo sum,” founding existence not on being-in-the-world, but on thought itself, on a thinking ego that objectified its own body and reduced creation to “res extensa,” to mere measurable and dominable extension. That dualism was not an academic error. It was the founding act of a civilization. Ours. The one built on domination, extraction, and a rationality that believed itself disembodied. What we call technological “progress” today often does nothing but dig that original furrow deeper. Nostr, in its formal elegance, digs toward the abyss. It mistakes freedom for isolation, neutrality for indifference, certainty for alienation. It sows wind in a field already too arid.

“Most of those who have written about the emotions and human conduct seem to deal not with natural phenomena that follow the common laws of nature, but with phenomena outside nature. They seem to conceive man in nature as a kingdom within a kingdom…”

These words by Spinoza, the great adversary of Cartesian dualism, resonate as a warning. Man as a “kingdom within a kingdom” is the lethal illusion. It is the subject who believes himself sovereign over a territory called body and a colony called world. But the body is not a territory. It is ourselves. And the world is not a colony. It is the substance of which we are a part. The protocol that promises to free us from bodies and places (“onlife,” as they say with a sinister neologism) does not elevate us: it amputates us. It delivers us to an eternal digital present, to a floating consciousness that has lost its sensory, emotional, communal anchor. Morality, uprooted from teleology (from the “end” proper to an embodied and relational being), becomes a consensus algorithm or a private preference. Solidarity, separated from the physical community of destiny, turns into a like, an ephemeral retweet. Human beings, uprooted from the living Earth, become nodes in a network, ghosts in a machine.

The Body that Knows: The Spinozist Revolt against the Empire of the Mind

To understand the scale of this amputation, one must listen to the forgotten voice of Baruch Spinoza. While Descartes started from hyperbolic doubt about the world to arrive at the certainty of the thinking self, Spinoza started from the world, from Nature (Deus sive Natura), of which man is a small part. A part, not an emperor. In this radically monist vision, mind and body are not two heterogeneous substances that mysteriously interact (the unresolved puzzle of Cartesian dualism). They are the same thing, conceived under two different attributes: thought and extension. The order and connection of ideas is identical to the order and connection of things. The body is not the prison of the mind, nor its machine. It is its way of being in the world, its constitutive interface. Without the body, the mind would not even know it exists.

Spinoza placed the body at the center of his philosophical investigation, a revolutionary act in a tradition that had despised it. He wrote: “No one has yet determined what the body can do”. It is an admission of ignorance that sounds like a prophecy. Our hyper-rational civilization, obsessed with mapping the mind and surveilling data, has systematically ignored the wisdom of the body. Its environmental intelligence, its cellular memory, its conatus: the intrinsic striving to persevere in its own being, which is desire, appetite, vital energy. The algorithm cannot encode the conatus. It can only stimulate or inhibit it, as it does with every “affect,” increasing or decreasing our power to act. Nostr, in wanting to transcend the body, transcends the human. It creates a soulless abstraction, or rather, one without true affects. Because affects – joy, sadness, wonder – are first and foremost affections of the body. They are our anchor to the real. A post can describe a sunset, but it is not the breath taken away before it; it can declare love, but it is not the warmth of a hand. The network, without the body, is a desert of signs. And we, within it, are like the waves of the sea Spinoza spoke of: “agitated in many ways by external causes… tossed about here and there, ignorant of our outcome and our destiny”. Nostr does not calm this sea. It merely makes it virtual, deluding us into thinking we govern its currents.

The Trace and the Ghost: Social Ontology in the Age of Abstract Documentality

The problem deepens when moving from the philosophy of mind to social ontology: how is our shared reality constituted? What is a historical fact, a document, a promise? Here too, the protocol plays with the fire of separation. Thinker John Searle explained social reality through “collective intentionality”: “X counts as Y in context C”. A rectangular piece of paper (X) counts as a twenty-dollar bill (Y) in the context of the United States (C). It is an act of collective faith, sustained by institutions. Searle’s theory, however, is based on background beliefs and speech acts, elements that are by nature variable and interpretable. What happens when this process becomes purely algorithmic and decontextualized? When the “context C” is no longer an embodied culture, but the immutable rules of a protocol?

Contemporary thought on Documentality offers a different key, more resistant to nihilistic drift. Social reality is constituted not only in intention, but in the trace, the material or digital inscription of an act. The document (in a broad sense) precedes and binds interpretation. It has its own opacity, its own inemendability. The yellowed parchment, the notarial register, even the post on a federated server: they are traces that bind us to a fact. Nostr, in theory, is a gigantic system of documentality: every note is a signed, immutable trace. Yet, in radically separating the trace from the body that produced it, from the place where it was conceived, from the physical community that gives it meaning, it risks emptying it. It reduces it to a ghost of itself. Searle’s “status function” could, in such an ecosystem, iterate infinitely in uprooted contexts, until losing all contact with the original reality of the acts. An agreement, a declaration of love, a piece of news become semantic strings floating in a sea of other strings. Truth is no longer an adequation to shared reality, but a coherence with the ledger of the chain. It is a triumph of nominalism that kills the thing.

This touches the heart of the historical and political question. A realist historian, a certain line of thought reminds us, believes that the process of historicization must bring out the objective connotations of a fact, freeing them (as much as possible) from the emotional involvements of the present. But this process requires confrontation with traces in their concreteness and their relationality. It requires a body that looks, a brain historicized by intersubjectivity. An abstract, de-historicized brain is a dangerous illusion. Nostr, by proposing a square where everyone is present only as uprooted intelligences, constructs the perfect condition for a non-history. An eternal and flat chronicle, where everything is recorded and nothing ever truly happened, because it happened outside the world. The “neutrality” of the protocol risks being the indifference of the digital cemetery.

Towards a Digital Pananthropology? The Embodied Brain and the Rooted Network

Is there a way out, then? Or are we doomed to dig the Cartesian furrow until ecological and social collapse? The answer, perhaps, lies in refusing the question itself, which is still dualist. It is not about “integrating” the body into the digital, as one adds an accessory to a machine. It is about recognizing that every technology is already an extension of our social and cognitive body, and as such, it absorbs and amplifies its pathologies or virtues. The neuroscientist and the philosopher of mind who ignore the intersubjectivity and historicity of the brain commit the same error as the Nostr designer who ignores the user’s corporeality. The brain becomes mind only in the encounter with the other, in the interiorization of language and culture. A disembodied mind is an oxymoron.

The challenge is not technical; it is ontological and ethical. It requires what has been called a “pananthropological” approach, which rejects disciplinary separations just as it rejects the mind-body separation. We must imagine protocols that, instead of uprooting, root. That, instead of abstracting, embody. That, instead of the blind certainty of the cryptographic signature, promote trust nurtured by shared vulnerability and proximity. We must relearn Spinoza’s lesson: freedom is not the absence of determinations (the libertarian dream of every crypto-anarchist), but the active understanding of the determinations that constitute us. To be free is not to be isolated nodes in a network, but to understand that we are part of Nature, and to act in accordance with this understanding, increasing our power to act and that of others.

The Nostr protocol, as it is conceptualized, represents the apex of a reason that has forgotten it is in the world. It is the latest expression of that will to power which, after declaring God dead, made Technology its new idol, also transcendent and separate. But an idol does not save. It burns. It burns bonds, burns meaning, burns the very earth we tread. Building a civilization on these metaphysical grounds is not progress. It is a slow suicide. A suicide committed with the cold, impeccable logic of one who has mistaken life for its map, the body for its ghost, and the living Earth for a database from which to extract value until the last bit.
