Is a naturalistic theory of communication possible?

This article presents a theoretical discussion of the relationship between language and communication. I discuss Chomsky’s position on this topic. Chomsky claims that if it is possible to construct a scientific theory of the language faculty, there is no possibility to construct a scientific theory of communication because in communication human intentionality is involved. This position is contrasted by philosophers of language considering that communication is to be studied as a form of rational action. I maintain that both these positions are not supported by the evidence coming from developmental research. Taking a cognitive point of view I contend that a communicative faculty can be defined that develops since infancy to adulthood, which has features independent of language and action. Different steps in the development of the communicative ability are linked to a parallel development of the theory of mind. I then argue in favor of a distinction between collective action and communication considering that while collective action is common to human and nonhuman primates, communication is typically human.
