In the article it is considered the problem interpretation for V.I. Vernadsky’s idea of noosphere. It is noted that interpretation problem arises as a result of equivocality - noosphere is used both as science concept and philosophical idea. The aim is to clarify the source of the noosphere equivocality. V.I. Vernadsky’s text "Scientific Thought as a Planetary Phenomenon" is presented as a source of this equivocality. A special feature of this text is the character of communicative situation as a situation of interaction between the author and the reader. As for the author text is a scientific one and noosphere is presented as a scientific concept, according to Vernadsky, it allows its meaning to be uncertain and incompleted. As the meaning uncertainty gives interpretation freedom, text takes the philosophical form for the reader and noosphere is philosophical idea. It is raised the question on combining philosophical and scientific texts in Vernadsky's work. In order to work out this question the concept of “text format” is used. It is formulated the thesis that in the Vernadsky’s work scientific and philosophical texts formats are interfered. The scientific text format is characterized as author’s monologue, which informs the reader about the text subject. The philosophical text format is characterized as the dialogue which initiates the reader’s reflection activity. It is concluded that noosphere interpretation problem arises due to the fact that Vernadsky’s text, where noosphere idea finds its explication, does not fit into the framework of cultural and historical boundaries between the philosophical position of self-knowledge and the scientific position of nature knowledge.
