The paper offers a systemological interpretation of the anthropocentric approach in linguistics from the point of view of its heuristicity in the analysis of feedbacks of a natural language with the environment. We emphasize ontologically conditioned connection of the language system with the conceptual one, which is the most important component of the environment for the language formation and functioning. Using the descriptive method, as well as the methods of conceptual, contextual, definitional and word-formation types of analysis, the work specifies the constitutive role of positive feedbacks that ensure the functioning of language as a means of cognition. The author considers some language phenomena illustrating the results of this type of connections in the representative side of the language, and also identifies the role of normative phenomena in the implementation of negative feedbacks that contribute to the communicative stability of the language system. It is concluded that the inclusion the relations of language with the environment in the linguistic research makes it possible to more fully characterize the flexibility of its system and explain qualitative changes focused on current cognitive tasks.
