Abstract

In this article I argue that there are metaphoric pictures and that pictures have propositional content; but, I also argue, it does not follow that metaphoric pictures are to be explained in terms of metaphoric content. I develop a "comparison" or "predication" approach that stresses that metaphoric pictures depend on their use in contexts that invoke relevant background knowledge. Our competence with metaphoric pictures is a nonsystematic, nonspecifiable competence because it consists in our ability to harness any variety of relevant background knowledge on the basis of contextual factors. It follows that insofar as our competence is not systematic, it is not possible to have a theory of metaphoric pictures, in the sense of a systematic specification of the types of factors or principles that allow one to grasp that a picture is metaphoric and what the metaphor is.
