 Languages of Art prompted a lively debate especially concerning Goodman’s claims about the nature of pictorial representation, or depiction. According to Goodman, the symbolic function that is distinctive of pictures is denotation (1976, Chap. 1)—hence pictures are labels and in that respect are analogous to linguistic predicates. The characteristics that distinguish pictorial systems from other denotational systems (e.g., from natural languages) make them the very opposite of a notation: pictorial systems are dense throughout and in that respect are similar to other analog systems, such as those of diagrams and maps (1976, 194–198; Goodman, Elgin 1988, Chap. 7).
