In the article, the following types of utopia are described: real and utopian utopias. The former are a projection into the future of such thoughts which have a chance to materialise, become certain reality. The latter are fantasy which has no chance to materialise. In the context of such distinction, the author analyses utopia of Karl Marx and Friedrich Engels. Their utopia, building communism, is realistic. Many of its elements have already been realised. Furtherdevelopment of social existence may however cause thet the utopia of communism will become the utopian utopia, i.e. will transform into fictional fantasy. Why this may happen? The article is an attempt to answer the above question. In my view, the reason for such situation is the fact that both Marx and Engels got stuck in the culture.
