 The locution of representation-as functions in the following way: an object \(X\) (e.g., a picture, statue, or model) represents a subject \(Y\) (e.g., a person or target system) as being thus or so \((Z)\). The question then is what establishes this sort of representational relationship. The answer requires introducing some of the concepts Goodman and Elgin use to develop their account of representation-as.
