Chiasm: Intercorporeality and sociality
“For Merleau-Ponty, the mother-infant relationship is the primordial example of intercorporeality and sociality. His later descriptions of the chiasm of flesh with its reversibility and divergence or spread (ecart) will facilitate our understanding of how mother is as bodily open to her infant as he is to her.” (Wynn, 1997: 254)
