Thus, we will try to briefly elaborate on several tendencies about contemporary art in the Republic of Macedonia, by ＂screening＂ the theoretical discourses on the issue and by critical perception of recent practices concerning the field. Today＇s views on the creative practices, incorporated in ＂conceptual＂ packages that should develop a new culture of living, are manifested in the creative industries, have been just recently recognized in the Macedonian society. The ＂propaganda＂ character of the treatment of artistic practice changes only formally the media of their manifestations. The idea about the possible and necessary engaged attitude of art towards society had its place also in the modern as well in the postmodern concept of art. In the Republic of Macedonia this ＂ideological＂ attitude towards art regretfully has also become the main mechanism for political domination, manifested mainly in architecture and landscaping of public space. The commercialisation of art supported by the media imposes the discourses of popular art over the content of high art. It seems that art is represented in the field of ＂education and science＂ in the Republic of Macedonia only when certain pragmatic, frequently politicised, interests need to be satisfied.展开更多
