Abstract
The central topic of this paper is the analysis of the dialectical interdependency of internal and external in the theory of language as a symbolic system. Referring to and analyzing the philosophic legacy of W. von Humboldt, B. Russell, L. Wittgenstein, F. de Saussure and G. Spet, the author concludes that the dialectics of internal and external is not an accidental and episodic phenomenon of language. It rather is an intrinsic, ontological trait apart from which an adequate cognition of the essence of language is impossible. Taking the internal form as a logical structure, it is possible to view it as something "higher and fundamental" in language, something that is attainable more by intuition than by research. The internal intellectual base of this grammatical stability lies in the sphere of purely logical forms. If internal word formulations are related to and governed by the spirit, then the external forms in fact conceal an inner grammatical and syntactic edifice. The laws of external speech functioning are manifested, for example, in bilingualism, which may be viewed either as a social phenomenon related to individual thinking and classificatory abilities or as an evidence of the existence of common verbal structures in human consciousness. The author proposes to transfer such linguistic terms as "bilingualism" and "contamination" into a different context as a way of seeking new topical domains within the linguistic philosophy and the philosophy of language. The empiricism of specific language functioning in the form of bilingual language contamination brings us back to the assumption of the existence of uniform internal metalanguage structures of verbal thinking.
