The research methodology is based on the interdisciplinary nature of the problem under discussion and involves inductive-empirical, objective-analytical and psychological studies. The principles of philological, psychobiographical and comparative-historical research methods, as well as the achievements of the latest methodology: phenomenology, literary hermeneutics and receptive aesthetics are applied. As a result of scientific research, the peculiarities of combining in Vasyl Stefanyk’s creative experience the general regularities of the procedural structure of creativity with individual and unique manifestations have been clarified.
