Maurice Merleau-Ponty and the Concept of Chiasm

Chiasm, reversibility-this is the idea that every perception is accompanied by a counter-perception; it is a two-sided act, and we can no longer tell who is speaking and who is listening. The circularity of speaking-listening, seeing-being seen, perceiving-being perceived (it is this that makes it seem to us that perception takes place within the things themselves)-Activity = passivity.
