In the contemporary scientific and socio-political space the works of K. Marx are in total oblivion. Even more, during the whole 20th century in the Western countries, and lately in the Eastern ones, he is anathematized politically and scientifically as an evil spirit. And still - is the scientific heritage of Marx actual and useful in the contemporary realities? Stating such a question in public today sounds almost like a provocation. Science, though, has its own rules, which define its moral. The paper is an attempt, firstly, to show, that despite the fact that it looks paradoxically at first, the theory of Marx is not only actual, but in the new realities will become even more actual. Secondly, the paper gives arguments for the fact that the intransient significance of Marx' ideology more adequately identifies and meets the global challenges, which the whole humankind has faced and still faces.
