Philosophical discussions of depiction sometimes suffer from a lack of differentiation between several questions concerning the nature of pictorial representation. To provide a suitable framework I distinguish six such questions and several levels on which one might want to proceed in order to answer some of them. With this background, I reconstruct Goodman's and Elgin's answer to the specific question: What distinguishes the pictorial from the verbal or linguistic? I try to reveal some major motivations behind their system-oriented approach and (...) to indicate some reasons why a strategy of this kind is to a certain extent mandatory to grasp the nature of the pictorial. The system-relative and functional character of depiction has to be captured by every adequate theory. (shrink)
