Introduction. In the modern world, the problem of the purpose of art remains relevant due to the emergence of various forms of non-classical art. Modernism and postmodernism differ from classical art, therefore it is inappropriate to transfer the purpose of classical art to these movements without a deep analysis. It seems reasonable for the analysis of non-classical art to consider it through the spectacles of Russian religious philosophy. Theoretical analysis. Representatives of the philosophy of unity and the representative of religious existentialism N. A. Berdyaev wrote about the purpose of classical art. The question arises: what is the purpose of non-classical art – modernism and postmodernism? The philosophers themselves – V. S. Solovyov, S. N. Bulgakov, N. A. Berdyaev analyzed works of classical art and modernist works. The author analyzes the artifacts of postmodern art through the spectacles of Russian religious philosophy. Conclusion. For a deep analysis of works of non-classical art, the criteria developed in the philosophy of unity should be used, since any work of art can be evaluated for the author’s desire to realize unity and from the point of view of actualization of eternal ideas. It is also possible to use the concept of Berdyaev’s creativity for the analysis of modernism, but this concept is not applicable for evaluating the art of postmodernism.
