The Crisis of Sensibility

In The You On AI Field Guide

The mechanism of erosion is attentional. Sensibility requires time — time to register a phenomenon fully, to let its qualitative dimensions unfold, to respond to its complexity rather than its headline. The accelerated semiosphere demands rapid processing. The nervous system adapts by processing semiotically rather than sensibly — assessing signs for functional adequacy rather than experiential richness, optimizing for efficiency rather than meaning, treating qualitative dimensions as noise to be filtered rather than signals to be attended to.

The erosion is gradual and largely unconscious. The builder does not notice that she is losing sensibility because the loss occurs at the level of micro-perception — at the split-second judgments that determine whether a particular stimulus receives deep or shallow processing. Over time, the accumulation of shallow processing reshapes the nervous system's default mode. Speed becomes habitual. Depth becomes effortful. What was once the natural mode of perception becomes a discipline that must be deliberately cultivated against the grain of trained reactivity.

The consequences extend beyond individual experience. Sensibility is the foundation of what Berardi calls conjunctive communication — communication that connects bodies and minds through shared experience. It is also the foundation of aesthetic experience and ethical judgment, the perceptual ground from which beauty and injustice become recognizable as such. A culture whose sensibility has been eroded cannot produce the art, the ethics, the political solidarity that depend on the capacity for embodied, resonant perception of the qualitative.

In the AI moment, the crisis of sensibility is sharpened by the specific character of human-machine exchange. The builder who must evaluate AI output at conversational speed is training her nervous system to process for functional adequacy rather than aesthetic or ethical weight. The aesthetics of the smooth that Byung-Chul Han diagnoses is both cause and symptom — content optimized for easy processing trains the capacity for easy processing, which demands more smooth content, which further erodes the capacity for difficult processing.

Origin

Berardi developed the concept across multiple works, with particularly sustained attention in The Soul at Work (2009), Heroes: Mass Murder and Suicide (2015), and Breathing: Chaos and Poetry (2018). The concept draws on phenomenological traditions — particularly Merleau-Ponty's analysis of perception — and on the psychoanalytic tradition's attention to affect and the body.

The framework has acquired urgent new application in discussions of AI's effects on human perceptual and ethical capacities, particularly in the work of scholars like Shannon Vallor and Arne Vetlesen.

Key Ideas

Sensibility as embodied. Not sentiment but integrated body-mind perception of qualitative dimensions.

Speed as antagonist. Sensibility requires time that the accelerated semiosphere does not provide.

Gradual and unconscious erosion. The loss occurs at levels of micro-perception invisible to conscious awareness.

Foundation of ethical capacity. Injustice must first be perceived; the erosion of sensibility undermines the ground of ethical response.

Training by exposure. The nervous system adapts to its environment; prolonged exposure to accelerated semiosis reshapes perceptual defaults.
