DISCURSIVE ASPECTS OF LINGUAL REALIZATION OF THE UNCERTAINTY PRINCIPLE
The paper focuses on the analysis of lingual realization of the uncertainty principle through the perspective of discursive categories and is based on the material of the British postmodern fiction discourse. The research determines the key role of the uncertainty principle for postmodern discourse with its tendency to reflect indeterminacy, ambiguity and plurality characteristic of postmodernism. This principle is acknowledged as the basic principle of postmodernism. The principle of uncertainty applied to linguistic range of issues is termed as the pattern of interaction between parameters of interconnected opposed lingual phenomena. It expresses the inversely proportional dependence between linguistic variables. The deeper exposure of one feature of the language phenomenon, the more indefinite other parameters come forward. It is stated in the paper that the uncertainty principle applied to discourse problematics reflects the discursive ambiguity as discourse is an open lingual system that combines the elements of statics and dynamics. The research outlines the most effective categories through which the uncertainty principle is manifested in the British postmodern discourse, namely the discursive categories of referentiality (which reflects the interaction between the discourse and reality) and intertextuality (conveys the links between texts inside a discourse and between various discourses), the factual material also reveals the relevance of the categories of anthropocentricity (with the sub-categories of the sender and addressee that determine the discourse anthropocentres) and informativeness (with the sub-categories of factuality and emotivity which express the relations between informative and emotive layers of a discourse). To a smaller extent the uncertainty principle is actualized through the categories of integrity, discontinuity, coherence, discursive time and space. The analysis of postmodern categories’ discursive actualization certifies that the basic function of the uncertainty principle in a discourse is transference of the focal center that causes the discursive divergence of vectors of authorial intention, material presentation of and reader perception. The investigation states the methods of the uncertainty principle actualization in the British postmodern discourse such as clustering lingual means of different levels, discursive non-linearity and self-organization, rhizomatic discourse arrangement, ramified architectonics, interpretational plurality, thus the postmodern fiction discourse is viewed as open, it envisages the wide spectrum of interpretations. Extrapolation of the uncertainty principle on the discursive range of problems exposes its relevance for reflection and interpretation of reality by the fiction discourse.
