The course focuses on the relationship between art and ideology in modern art of the first half of the 20th century and on the developments of these relations in postmodernism and contemporary art. In this seminar, the term "ideology" is interpreted not only in the direct socio-political sense, but also in the aesthetic aspect ("aesthetic ideology"), as well as in the sense of "totality of values" of any type. We will discuss ideological issues related to the concepts of "art for art's sake" ("pure creativity", "aestheticism"), "art mobilized", and the art of a socio-political "agenda" from the point of view of aesthetic and sociological theories.
