Based on the theory of genius presented in Kant’s Critique of Judgement, the author considers the idea of normal genius as opposed to the genius of Romanticism and Postmodernism. The influence of Postmodernism is manifested in popular interpretations of the works of great artists — especially, Russian ones — as a product of mental disorders and perversions. The author analyses an interpretation of the oeuvre of the great Russian poet and thinker A. A. Fet. Factors that affected the fundamentals of A. A. Fet’s world view are considered. The author proves that the influence of the Moravian Church in Võru, where the poet studied there for several years, was insignificant.
