In this paper I discuss a generalization of communication theory. I sketch a model of the communication situation sufficiently general to subsume all models of particular aspects of communication. Several definitions and lines of inquiry are proposed. It will be evident that much of what I say has been influenced by Bar-Hillel, and also that this paper goes beyond Bar-Hillel's both in generality of scope and in details of analysis. The more general aim of the paper is to suggest a (...) reconstruction of our intuitions regarding communication. In particular, I argue that we should drop the idea that anything is “conveyed” in communication. (shrink)
