Abstract
In contemporary human sciences, the concept of activity continues to play a key, methodologically central role, since it is used in attempts to give a universal characterization of either the whole human world or the inner world of a concrete individual . In either case, the category of activity is elevated to the level of a universal, ultimate abstraction, which, in E.G. Iudin's words, "combines empirical certainty with theoretical depth and methodological constructiveness" [11, p. 249]
