As a living soul of civilization, Marx lives in the secular intellectual process and in the relationship between philosophical criticism and its own environment. The approach to Marxist philosophy studies lies, therefore, in how to understand the way philosophy grasps the world, in the way to make the world-changing philosophy keep up with the times and in the height of scientific world outlook the theoretical thinking can possibly reach in face of problems of the times. The height and realistic characteristics of Marxist philosophical outlook are not reappearance of abstract principles in the historical movement, but, first of all, reflections and criticisms premised on practice. Lack of consciousness of practical problems is an expression of theoretical infantilism. It is in the sense of being capable of solving practical problems or providing the methodology for solving practical problems that Marxist philosophy displays its scientific nature.
