Neopositivist grounds of denial and opportunities of prediction in the K. Popper knowledge system

The relevance of the work is caused by the need to analyze the grounds of denial and prediction of knowledge in the K. Popper neopositivist concept. The objective of the study is to analyze the problem of neopositivist grounds of denial and prediction in the K. Popper knowledge system in the aspect of knowledge development current trends; to justify the assumption that the statement of the falsificationism concept author on existential form of deduction and impossibility of elimination of axiomatic form structuring knowledge system, is an implicit recognition of the presence of a priori factors. The methods of the research: comparative method allows us to carry out the correct analysis of various concepts and mythologems in diachronic level; this approach provides a reasoned comparison of the discourse constitution principles at different historical stages, which are caused by the shift of meaning of concepts and mythologems; phenomenological method allows us to show the way and the bases of «redistribution» of the meaning of rational and irrational factors that determines the configuration of this or that discourse in a particular cultural and historical level. The results of the study: The author has made an assumption that appeal to meta-scientific character of knowledge is pure and simple recognition/statement of interconnectedness of knowledge system to the irrational status; and formulated arguments of the statement that the explanatory theories specified by K. Popper neither have a direct relation to our cognitive abilities nor the mathematical structures, being logical-epistemological description of the continuum, in any way correspond to the represented given continuum object.
