My goal in this paper is to defend the plausibility of a particular version of collectivism - understood as the evolutionary claim that individual-level cognition is systematically biased in favor of aggregate-level regularities - in the domain of language. Chomsky's (1986) methodological promotion of I-language (speaker-internal knowledge) and the corresponding demotion of E-language (aggregate output of a population of speakers) has led mainstream cognitive science to view language essentially as a property of individual minds/brains whose evolution is best explained as a result of the natural selection of an innate language faculty (Pinker 1994). Such a framework is largely oblivious to the linguistic dynamics arising from iterated learning, i.e. the fact that linguistic information must be periodically mapped from its I-linguistic into its E-linguistic medium and back in order to persist over time. Recent expression/induction models of language evolution, which are heavily inspired by the simulation-based methodology of Artificial Life, suggest that linguistic universals, such as compositional and recursive structure, can emerge from cultural selection alone (Brighton et al. 2005). I will conclude that there is both a biological and a cultural route towards collectivism.
