A classical objection to pictorial communication is that pictures are intrinsically ambiguous and a picture, per se, can communicate an indeterminate number of different contents. The standard interpretation of this objection is that pictures are subordinate to language and that pictorial communication is parasitic on verbal communication. We argue that in many cases verbal communication presents a similar indeterminacy, which is resolved by resorting to pragmatic mechanisms. In this spirit, we propose a pragmatic approach which explains pictorial communication in terms (...) of implicatures in a wide sense. (shrink)
