Proprioception (Sheets-Johnstone Reading)
The body's continuous awareness of its own position — the ground of the sense of self, operating beneath reflection, and systematically dulled by screen-based work.
Proprioception is the body's awareness of its own position and movement in space, generated by receptors in muscles, tendons, and joints that continuously report the body's configuration to the central nervous system. Sheets-Johnstone identifies proprioception as the ground of the sense of self — not the narrative self with its name and history, but the primordial self that exists before narrative: the felt sense of being a body that occupies space, has boundaries, moves and is moved, encounters a world from a specific location. This primordial self is proprioceptive. It is bodily self-knowledge that operates continuously beneath reflection, providing the kinesthetic grounding on which every other form of self-awareness is built. When proprioception is compromised — by neurological damage, or, more slowly, by the chronic immobility of screen-based work — the sense of self thins correspondingly.

The neurological evidence for proprioception's foundational role is striking. Patients with rare proprioceptive neuropathies — Ian Waterman, documented extensively, is the canonical case —
