Thinking with words: the role of externalization

Abstract According to Chomsky and followers, natural language is a computational system that generates syntactic structures that are counterfunctional with respect to communication. Consequently, language is more appropriately considered as being “designed” for thought rather than communication. In this paper, we argue that, while natural language, understood as an internal computational system along standard generative lines, is recruited for distinctive human thinking, such recruitment also requires, and is strongly influenced by, a process we dub lexical externalisation . We first show that there is good reason to believe that the atomic items that go to form words essentially include phonological information of externalised words. After that, we explore what externalisation implies with respect to the relation between lexical items and concepts. We suggest that externalisation has profound effects on what concepts we think with, as well as how concepts relate to lexical items (i.e., how thinking processes ultimately relate to linguistic computations).
