ABSTRACT
One fundamental contribution of what we have been calling “Cartesian Linguistics” is the observation that human language, in its normal use, is free from the control of independently identifiable external stimuli or internal states and is not restricted to any practical communicative function, in contrast, for example, to the pseudo language of animals. It is thus free to serve as an instrument of free thought and self-expression. The limitless possibilities of thought and imagination are reflected in the creative aspect of language use. The language provides finite means but infinite possibilities of expression constrained only by rules of concept formation and sentence formation, these being in part particular and idiosyncratic but in part universal, a common human endowment. The finitely specifiable form of each language - in modern terms, its generative grammar -provides an “organic unity” interrelating its basic elements and underlying each of its individual manifestations, which are potentially infinite in number.
