In the paper the author deals with the question of the significance of problems of human individuality in the Marxist socialphilosophical theory. He argues that Marxist theory of social-historical development is simultaneously a theory of human individuals and their development. In Marxism social history is conceived in its humanistic content as the history of the development of individuals and their liberation. The problem of individuals does not appear as an independent appendix (though in relative sense) of the theory of social-historical development, on the contrary, it is its inseparable organic component. The forming of individuals is not interpreted here either as a process going along the social-historical process or as a specific process which is subjected to specific logic. It is an identical process of the social development which is simultaneously a process of the individual development of men. The author shows that here a specific plane of approach to the problem of the individuality is the case, which has nothing in common with „sociologism“.
