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.
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, "a symbolic form... is not some 'intermediary' in a process of 'communication' that transmits the meaning intended by the author to the audience; it is instead the result of a complex process of creation that has to do with the form as well as the content of the work; it is also the point of departure for a complex process of reception that reconstructs a 'message.'"
