The internal, the external and the hybrid: The state of the art and a new characterization of language as a natural object

The state of the art of the debate between externalist and internalist concepts of language is reviewed in this paper, and a new conceptualization of language as a “developmental hybrid” is suggested that entails that it equally comprises environmental and organism-internal component pieces, in an ultimately non dissociable way. The key for understanding this hybrid status is to be found in development, for when individually evolving, a general dynamic is observed in which organism-internal facilities selectively apply to certain designated aspects of the environmental stimulus, which in their turn have a facilitatory impact on these very same facilities. These kinds of loops inspire the conclusion that the internal and the external compose a single, integrated developmental unit.
