Abstract: The article is devoted to the aesthetic development of Friedrich Wilhelm Joseph Schelling and his successive change of the methods of acquiring new principles in comparison to his famous predecessors in Germany. Schelling's philosophy of nature, full of romanticism and spirit, has been called 'the poetry of nature' with good reason. Inellectual intuition and aesthetic intuition played the main role in the development of the new approaches of his easthetic philosophy. His philosophy is most of all represented in his work 'The Philosophy of Art' where Schelling offered the original classification of art based on their historical analysis from ancient to new European times (from 'naive' art to 'sentimental' or 'romantic' art). Schelling's became very popular with Russian philosophers who heard his lectures and knew him in person. In the methodological meaning, the present article is aimed at describing Schelling's views from the point of view of their dialectic development, from unconscious creative activity to a rational concept created as a result of intuitive insights. The scientific novelty of the present article is that the researcher provides a full description of creative searches and findings of the philosopher and unoconscious activity of a creative personaity which still remains an important topic for theoretical researches. Russian aesthetics, historiosophy and philosophy of the all-encompassing unity ('vseedinstvo') with the central idea of theantropism developed under the impression and influence of Schelling's teaching.
