 At a first approximation, Goodman’s claim that “denotation is the core of representation” (1976, 5) means that pictures are pictorial labels for their subjects, individuals or sets of individuals, analogously to how names, or predicates, or verbal descriptions are linguistic labels for their denotata. Yet, of course, not all pictures that have a subject—i.e., all pictures that are representational, versus images that are non-representational or abstract—have an actual individual as their subject. Some pictures have just a generic subject (say, a picture of a man, in the sense of a picture of no man in particular), others have a fictional subject (a picture of a unicorn, for example). Goodman’s account of such cases is in terms of multiple denotation for the former and null denotation for the latter. Some pictures—exemplary is an illustration of an eagle placed, in a dictionary, next to the definition of the word “eagle”—refer, severally, to all the members of a given set, such as the set of eagles. Other pictures, such as pictures of unicorns, refer to nothing, since there are no unicorns in reality: they have null denotation. Goodman insists that the existence of pictures with null denotation does not represent a problem for the view that claims that “denotation is the core of representation.” Such pictures are, of course, to be distinguished from other pictures with null denotation, such as pictures of Pegasus or of Pickwick. Yet, they are so distinguished in being pictures of a certain kind—unicorn-pictures—classified differently from pictures of other kinds, such as Pegasus-pictures or Pickwick-pictures.
