synaesthesia

The blending of senses — seeing-feeling-hearing-smelling as a single act, before the mind sorts the experience into separate channels. Clinically, a rare condition in which stimulating one sense triggers another (hearing colors, tasting shapes). But Abram, following Merleau-Ponty, argues synaesthesia is our primary, preconceptual mode of perception — the way a body actually meets the world before we learn to divide it. The wind in an aspen: you cannot separate the sight of trembling leaves from their whisper, nor either from the tension you feel in your muscles as the branches bend.
