Phenomenology taught us that the body is “bodily subjectivity” (le corps propre), a constant openness to the world, our only way of “being-at-things.” But in a situation of catastrophe or extreme pain, the body ceases to be a transparent medium. It becomes hermetic.
Pain does not expand the horizon nor does it grant new experience – it cancels the very possibility of co-presence. The world does not simply shrink; it is annihilated as a system of meanings, reduced to the burning radius of the nervous system. In these moments, intentionality – the very directedness of consciousness outward – is severed. The body no longer “sees” the world; it sees only its own boundary.
Here arises the temptation of biological reductionism: to identify our Vertical exclusively with muscle tension or the work of the vestibular apparatus. However, the body does not generate structure – it is merely the place of its ultimate, often unbearable manifestation.
Corporeality is a condition for accessing structure, not the source of its necessity. When the brain is destroyed, the structure as such is not annihilated – only the ability to enact it is destroyed. The difference between ontology and neurobiology lies exactly here: death is a physical event, not a logical argument. Death does not refute the Axis; it merely ends its transmission into this specific material. A radio receiver can be smashed, but that does not mean the wave has ceased to exist; it means it no longer has a voice.
If structure is enacted corporeally, it inevitably becomes tragic. It ceases to be a sterile idea hovering above suffering; it becomes a tension running through living muscle and nerve. It becomes something that can be interrupted by a bullet, illness, or time.
The Vertical is not posture. Posture is merely a temporary, fragile actualization of the Vertical in a biological subject. True thinking today is the recognition of this dependence without capitulation to it. It is the ability to hold the Axis, knowing that your bearer is finite, mortal, and vulnerable. Structure does not save the body from disintegration. It does something else: it prevents its fall from being mute. It gives the body a language to describe its own catastrophe.
However, there is a limit where even the Axis can no longer be enacted. This is the moment when the destruction of the bearer becomes so total that the structure loses its resonance. The recognition of this silence is the subject’s final act of honesty.
When the body finally falls silent, the structure does not vanish into nothingness, but it transitions into a mode of pure potentiality, devoid of a witness. Our task is to maintain this resonance until the very last millimeter of presence. To be human means to be that crossroads where the eternal structure of the Axis meets the fragility of flesh, creating a flash of meaning precisely at the moment of their inevitable rupture.
