The hand that touches the other hand is also being touched. The eye that sees is also visible. Neither role stabilizes; the experience is one of continuous, irreducible reversibility. This analysis grounds Merleau-Ponty's account of intersubjectivity — the recognition of other minds — and reveals, with precision, what is structurally absent in human-AI interaction: the reciprocal fold that would constitute genuine encounter between two body-subjects.
