Abstract: The subject of the research is the external and internal boundaries of science which define metamorphosis of non-scientific forms of knowledge at the boundaries of science. The object of the research is the relationship between science and non-scientific forms of knowledge from the point of view of their diachronic and synchronic dimensions. Special attention is paid to the boundaries outside which science cannot and should not be spread. It is due to the scientist's responsibility rather than the limits of the mind competence. Taking this into account, the problem of the boundaries of scientific or any other knowledge is related to the culture of rationality and thus acquires additional importance under new circumstances. The author of the article proves that destructive features of the industrial civilization where science plays the role of the innovative social code constitute grounds for the epistemological program of defining the boundaries of mind competence as it was introduced by Immanuel Kant. The main research method used by the author is the classical method of dialectics. This method allows to view the matter from the points of view of ontology, gnoseology, culture and history. When it was necessary, the author has also applied the phenomenological, hermeneutical and systems concept, thesaurus and contextual approaches to understanding and interpreting cultural phenomena. According to the author, philosophical interpretation of the boundaries of science or any 'other' knowledge is also important to understand the fact that there is no 'pure' science or 'pure' rationalism: the world of science involves a variety of other forms of knowledge (myth, theological concepts, intuition, mystical or esoteric experience); and all forms of knowledge are rational to a certain extent. In all cases metamoprhosis, interconversion and compatibility of all forms of knowledge at the boundaries of science and non-science can be observed. The article is devoted to philosophical problematic of the frontiers of scientific and other knowledge in the phenomenology of contemporary culture. Its leading sense acts to set the frontiers of science and other knowledge on the basis of ethical rationality and Biosphere ethics with a view to promoting the humanistic orientation of modern mankind in order to preserve the status quo and the intrinsic value of life itself.

Abstract: The object of the research is the phenomenon of parascience. The subject of the research is parascience as a cultural and historical phenomenon and subculture. The author of the article examines such aspects of the topic as the relationship between science and parascience from the point of view of their cultural and historical development as well as modern environment. The author also develops her own philosophical and cultural definition of parascience as a subculture that has evolved from marginality to antisystematicity. Special attention is paid to the aspect of the author's substantiation of essential features of parascientific destructive forms that try to look like science as well as the main characteristics of the parascientific subcultural complex. The author of the research bases her research of the cultural and historical phenomenology of parascience on the multi-disciplinary approach and philosophical-methodological concepts of culture taking into account chronotopos characteristics of an active concrete-historical individual involved in specific subcultural communities and groups. The main research method used by the author is a classical dialectical method. The novelty of the research is caused by the fact that the author focuses on the philosophical and theoretical problem of cultural and historical phenomenology of parascience because, first of all, solution of this problem can be found at the intersection of classical and non-classical methodological paradigms of knowledge based on ontological and epistemological grounds. According to the author, in order to solve the problem it is necessary to establish a philosophical and cultural concept of parascience as a subcultural formation in different cultural and historical knowledge systems. As the main conclusion of the research, the author offers her own philosophical and culturological definition of parascience as a subculture in terms of specifics of the parascientific discourse.
