The book of the famous Czechoslovak author Yaroslav Matejček, offered to the attention of the Soviet reader, is devoted to one of the most important and pressing problems of the modern ideological struggle. The sharp struggle between socialist and bourgeois ideology, as the author rightly notes, is waged in all the main sections of Marxism-Leninism. The center of this struggle is socio-political teaching, and the attention of our ideological opponents is concentrated primarily on the problems of the state, democracy and the political system as a whole.
