Bühler’s model of communication is that of: ‘representation’ as ‘the capacity of a sign to refer to an external reality or referent’; ‘expression’ as ‘the capacity of a sign to express something about the sender of the message’; and ‘call’ as ‘the capacity of the sign to affect the receiver’. ^{28 28.} Bühler cited in Mukařovský, J. (1984) ‘Poetic Reference’, Semiotics of Art. Cambridge: MIT Press. It is easy to map these thoughts onto my own model of capture, storage, and release. To Bühler’s model Mukařovský (1984: 158) adds a fourth ‘aesthetic function’ where in a ‘reversal in the hierarchy of relations’ (ibid.: 157) we respond to the material object, the sign itself, before we read what it might signify. Poetic reference is made through appearance and context before we are able to consider representation.>>> While I arrived at my ‘energy transfer’ construct in advance of my thesis and prior to all of these readings, these formulations serve to frame a ‘state of the question’, through which I can situate my construct in a ‘larger ensemble’.>>>
