Esthesic and poietic

Esthesic and poietic are terms used in semiotics, the study of signs, to describe perceptive and productive levels, processes, and analyses of symbolic forms. The corresponding terms for the processes are esthesis and poiesis.
Like 'emic' and 'etic', both words appear to be derived from a suffix, -poietic meaning productive or formative and -esthesic being receptive or perceptive, in relation to the neutral level. The neutral level is the "trace" left behind, the physical or material creation of esthesic and poietic processes.
Thus, for Jean-Jacques Nattiez,
Nattiez's diagram, following Jean Molino:
"Esthesic" also refers to the mental perception of any body part. "-poesis"/"-poetics" also refers to production.
